Answer:
-7
Step-by-step explanation:
The two lines intersect at the point (6,10), so this point belongs to both lines. This means that if we use the value of x = 6 in the lines, we will find y = 10
So we can use this point to find the values of b and m:
y = mx + 4
10 = 6m + 4
6m = 6
m = 1
y = 3x + b
10 = 3*6 + b
b = 10 - 18 = -8
So the value of b + m is -8 + 1 = -7
After substituting the intersection point (6, 10) into both line equations and solving for m and b respectively, we find that the value of b + m is -7.
To find the value of b + m when two lines intersect at the point (6, 10), we can substitute the coordinates of the intersection point into both line equations. Since the coordinates (6, 10) must satisfy both equations, we have:
For the first equation y = mx + 4:
10 = m*6 + 4,
which simplifies to:
m = 1.
For the second equation y = 3x + b:
10 = 3*6 + b,
which simplifies to:
b = -8.
Having both values, we can now calculate b + m:
b + m = (-8) + 1 = -7.
The value of b + m is -7, which represents the sum of the y-intercept of the second line and the slope of the first line.
What is the approximate volume of the cylinder?
Answer:
The result for the volume of the cylinder:
[tex]V \approx452.389[/tex]
Step-by-step explanation:
-To find the volume of a cylinder, you need the formula:
[tex]V = \pi r^2 h[/tex]
-Use the radius and the height for the formula:
[tex]V = \pi 4^2 9[/tex]
-Then, you solve:
[tex]V = \pi 4^2 9[/tex]
[tex]V = \pi[/tex] × [tex]4^2[/tex] × [tex]9[/tex]
[tex]V = \pi[/tex] × [tex]16[/tex] × [tex]9[/tex]
[tex]V = \pi[/tex] × [tex]V = 144\pi \approx 452.389[/tex]
So, therefore, the volume is [tex]452.389[/tex] .

THIS IS A QUESTION FOR WOLLFGIRL Write out 2-4 sentences about which advertisement would give you the "best deal"
Answer:
answers are highlighted below! I hope this helps! please do not copy my work! ^-^ :)
Step-by-step explanation:
okay, on the first one we are told we have 15% off of $729.99
which then takes off about $109.50
after we subtract the $109.50 from the $729.99 we are left with $620.49, that's not including tax
sales ax is 8.25% or $51.19 that comes out to equal $671.69
so we can conclude that the big tv sale at the big box store is equal to the amount of $671.69
on the second one, its normally $699.99
we have the coupon for $100 off of that price so that leaves us with $599.99
but we have the $50 charge for delivery. so now its at $649.99
now we need to determine the price after tax. the price of tax is $53.62
add the tax amount to $649.99 to get $703.61
$703.61
the initial price of the tv is $734.95
$150 in rebate (refund)
$734.95 - $150 = $584.95
now we need to find the price including the delivery cost
$584.95 + $35 = $619.95
now lets find the tax price
$51.15
After Tax Price: $671.10
The TV from the Electronic Warehouse is the best option. You pay only $671.10! The prices from the two other stores are $703.61 and $671.69.
We are paying .59 cents less than one of the TV's, and we are also paying $32.51 less than the other TV! So the best option would be the TV from the Big Box store!

37.5% of the 24 students walk to school.
So, the number of students that walk to school is:
Students = 37.5% * 24
Students = 9
One third of the walkers got a ride to school today from their parents.
So, the number of students that got a ride is:

A rock group plans to travel for a total of 27 weeks, making three concert stops. They will be in Japan for 2 more weeks than they will be in Australia. Their stay in Sweden will be 2 weeks shorter than that in Australia. How many weeks will they be in each country?
Answer:
They spent 9 weeks in Australia, 11 weeks in Japan and 7 weeks in Sweden.
Step-by-step explanation:
A rock group plans to travel for a total of 27 weeks, making three concert stops in Japan, Australia and Sweden.
Let the number of weeks spent in Sweden be s.
Let the number of weeks spent in Japan be j.
Let the number of weeks spent in Australia be a.
This means that:
s + j + a = 27___________(1)
They will be in Japan for 2 more weeks than they will be in Australia. This means that:
j = a + 2 ______________(2)
Their stay in Sweden will be 2 weeks shorter than that in Australia. This means that:
s = a - 2 ______________(3)
We can replace s and j in (1) with (2) and (3):
=> a - 2 + a + 2 + a = 27
Collecting like terms:
a + a + a - 2 + 2 = 27
3a = 27
a = 27 / 3 = 9
The number of weeks they will spend in Australia is 9 weeks.
Putting this value of a in (2) and (3):
j = 9 + 2 = 11
and
s = 9 - 2 = 7
Therefore, they will spend 11 weeks in Japan and 7 weeks in Sweden.
Determine if the following system of equations has no solutions, infinitely many

James, a real estate appraiser is looking at homes in the 78681 zip code. He takes a random sample of 42 homes form the Austin MLS (that's where Realtors go for information) and finds that 29 of them are listed as "eclectic" style. What is the 80% confidence interval for the proportion of homes that are "eclectic"?
Answer:
80% confidence interval for the proportion of homes that are "eclectic" is [0.59 , 0.78].
Step-by-step explanation:
We are given that James takes a random sample of 42 homes form the Austin MLS (that's where Realtors go for information) and finds that 29 of them are listed as "eclectic" style.
Firstly, the pivotal quantity for 80% confidence interval for the population proportion is given by;
P.Q. = [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] ~ N(0,1)
where, [tex]\hat p[/tex] = sample proportion of homes that are "eclectic" = [tex]\frac{29}{42}[/tex] = 0.69
n = sample of homes = 42
[tex]\mu[/tex] = population proportion of homes that are "eclectic"
Here for constructing 80% confidence interval we have used One-sample z proportion statistics.
So, 80% confidence interval for the population proportion, p is ;
P(-1.282 < N(0,1) < 1.282) = 0.80 {As the critical value of z at 10% level
of significance are -1.282 & 1.282}
P(-1.282 < [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] < 1.282) = 0.80
P( [tex]-1.282 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] < [tex]{\hat p-p}[/tex] < [tex]1.282 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] ) = 0.80
P( [tex]\hat p-1.282 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] < p < [tex]\hat p+1.282 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] ) = 0.80
80% confidence interval for p = [ [tex]\hat p-1.282 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex],[tex]\hat p+1.282 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex]]
= [ [tex]0.69-1.282 \times {\sqrt{\frac{0.69(1-0.69)}{42} } }[/tex] , [tex]0.69+1.282 \times {\sqrt{\frac{0.69(1-0.69)}{42} } }[/tex] ]
= [0.59 , 0.78]
Therefore, 80% confidence interval for the proportion of homes that are "eclectic" is [0.59 , 0.78].

If the surface area of the box of cereal below is 272 in?, find the length of the box.
CEREAL
12 in
2 in
1=?
Answer:
x = 8 inches length
Step-by-step explanation:
Dimension of box:
12 inches by 2 inches by length x
with total surface area = 272 square inches,
There are 6 faces.
Area = 2 *(12 * 2) + 2 *(2*x) + 2 *(12*x)
Area = 272 sq. in. = 48 + 4x + 24x
272 = 48 + 28x
272 - 48 = 28x
224 = 28x
x = 8 inches
To find the length of the box, use the surface area formula of a rectangular prism and solve for the length. The length of the box is 59 inches.
Explanation:To find the length of the box, we need to calculate the dimensions of the cereal box. The surface area of a rectangular prism is given by the formula: Surface Area = 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height of the box. From the given information, we have:
12(2) + 12(1) + 2(2)x = 272
Simplifying the equation gives us: 24 + 12 + 4x = 272
Combining like terms, we have 4x + 36 = 272. Subtracting 36 from both sides gives us 4x = 236. Finally, dividing by 4 gives us x = 59.
Therefore, the length of the box is 59 inches.

Can a triangle with the angles of 0, 90 , and 90 be considered a triangle?
A "triangle" with the angles 0, 90, and 90 degrees cannot be considered a triangle since the two 90 degree angles make a right angle, and 0 degrees would mean a flat line. Rather it would resemble something like a straight U that is stretched sideways.
Final answer:
A figure with angles of 0, 90, and 90 degrees cannot be considered a triangle because the angles must sum to 180 degrees and each angle must be greater than 0 degrees and less than 180 degrees to form a three-sided figure.
Explanation:
A triangle is defined as a three sided figure lying on a plane, with three angles that add up to 180 degrees. In the case of the angles provided (0, 90, and 90), they do not add up to 180 degrees; instead, they sum up to 180 degrees if you exclude the 0-degree angle, which cannot be a valid angle for a triangle since every angle in a triangle must be greater than 0 degrees and less than 180 degrees. Therefore, a figure with angles of 0, 90, and 90 degrees cannot be considered a triangle.
In addition, the shape with two 90-degree angles would be a straight line, which does not meet the criteria of a triangle having three sides. An example of a valid right-angled triangle is one having angles of 90, 45, and 45 degrees, which correctly sum up to 180 degrees and form a closed three-sided figure.

The vertex of the function is at (1,-24).
The graph is increasing only on the interval -4< x < 6.
The graph is positive only on one interval, where x <-4.
The graph is negative on the entire interval
My answer:
Given the factored form of the function:
f(x) = (x + 4)(x-6)
<=> f(x) = [tex]x^{2} - 2x -24[/tex]
We will convert to vertex form

We choose: a. The vertex of the function is at (1,-25)
Let analyse other possible answers:
c. The graph is increasing only on the interval -4< x < 6.
Because the parameter a =1 so the graph open up all over its domain and the vertex is the lowest point.
So the graph is increasing in the domain (1, +∞)

hope this helped you
Final answer:
The given expression 5a−5a²−10a⁴ is factored as a product by factoring out the common factors, resulting in 5a(1 - a - 2a³).
Explanation:
To write the expression 5a−5a²−10a⁴ as a product, we need to factor out the common factors in each term. The term with the lowest exponent in 'a' is '5a', which indicates we can factor out 'a' from the entire expression. However, we can also factor out a '5' since it is common to all terms. Here are the steps:
First, identify the common factors in the terms which are '5' and 'a'.Factor out '5a' from each term in the expression.Doing this, we get: 5a(1 - a - 2a³)
The expression can now be expressed as the product of '5a' and '(1 - a - 2a³)'.
