Answer:

[tex]x+2y=-11[/tex]

Step-by-step explanation:

Slope intercept form of a line is given by:

[tex]y=mx+b[/tex]

Where

m is the slope and b is the y-intercept

Given slope is  [tex]-\frac{1}{2}[/tex]

We can write:

[tex]y=-\frac{1}{2}x+b[/tex]

Now to find b, we replace x with -3 and y with -4, given, so we have:

[tex]y=-\frac{1}{2}x+b\\-4=-\frac{1}{2}(-3)+b\\-4=\frac{3}{2}+b\\b=-5.5[/tex]

So, the equation is:

[tex]y=-\frac{1}{2}x-\frac{11}{2}[/tex]

Now,

The standard form is given by:

[tex]Ax+By=C[/tex]

So, we take x and y to left side and the constant to right side. Rearranging, we get:

[tex]y=-\frac{1}{2}x-\frac{11}{2}\\2y=-x-11\\x+2y=-11[/tex]

The first answer choice is right.

Final answer:

The equation of line b that passes through the point (-3, -4) and has a slope of -1/2 in standard form is x + 2y = -11.

Explanation:

To find the equation of line b that passes through the point (-3, -4) and has a slope of -1/2, we will start with the slope-intercept form of a line equation y = mx + b, where m is the slope and b is the y-intercept. While we know the slope (-1/2), we do not yet have the y-intercept. We can use the given point to solve for b. Plugging the point into the equation gives -4 = (-1/2)(-3) + b, which simplifies to -4 = 3/2 + b. Solving for b yields b = -11/2.

Now we have the slope-intercept form of the line: y = (-1/2)x - 11/2. To convert this to standard form, which is Ax + By = C, we multiply through by 2 to clear the fractions, which gives us 2y = -x - 11. Rearranging this, we add x to both sides to get x + 2y = -11. Therefore the correct equation in standard form is x + 2y = -11.

Answer:

2x+8>12

Step-by-step explanation:

Answer:

$remaining=86-6m

Step-by-step explanation:

$remaining = 80 - (m + 2m) - (3m-6)

$remaining = 80 - 3m - 3m +6

$remaining = 86 - 6m

80 -> total amount she brings into the store

m -> money spent on milk

2m -> money spent on fruit (two x m)

3m-6 -> bread (six dollars less than three times the milk value)

Simplify and the result is 86-6m

Answer:

The original price of the skirt is $24

Step-by-step explanation:

The complete question is

Jade buys a blouse and a skirt for 3/4 of their original price. Jade pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt?

Let

x ----> the original price of the blouse

y ---> the original price of the skirt

we know that

Three fourth of the sum of the original price of the blouse and the original price of the skirt, must be equal to the total paid for the two items

so

The linear equation that represent this situation is

[tex]\frac{3}{4}(x+y)=31.50[/tex]

we have

[tex]x=18[/tex] ----> given problem

substitute the value of x in the expression above and solve for y

[tex]\frac{3}{4}(18+y)=31.50\\[/tex]

Multiply by 4 both sides

[tex]3(18+y)=4(31.50)\\54+3y=126\\3y=126-54\\3y=72\\y=24[/tex]

therefore

The original price of the skirt is $24

Step-by-step explanation:

Answer:

13,200 feet

Step-by-step explanation:

So, the rocket starts descending at a given rate and time, so we first need to find the length it passed during that descent.

Length equals to speed multiplied with time:

s = v • t

since speed is given in feet per second, we need to convert minutes to seconds; if one minute has 60 seconds, then two minutes have 120 seconds.

s = 15 feet/s • 120 s

s = 1800 feet

So, the rocket descended 1800 feet, but it still has 11,400 feet to the Moon's surface. That means that the rocket was on 11,400 + 1,800 = 13,200 feet elevation when it started to drop.

Answer: Answer is 38ft.

Step-by-step explanation: The figure that measures 10ft by 9ft is a rectangle which means two sides measure 10ft each (length) and two sides measure 9ft each (width). A perimeter simply measures all sides of the entire shape, that is;

10ft + 9ft + 10ft + 9ft = 38ft.

The kite is a quadrilateral with 4 sides and angles. The length of line segment CD from the given kite is 28 units

The kite is a quadrilateral with 4 sides and angles.

From the given diagram,

AB = 3x + 1

BC = 22

Since AB = BC, hence;

3x + 1 = 22

3x = 22 - 1

3x = 21

x = 7

Since AD = CD = 4x, hence;

CD = 4x

CD = 4(7)

CD = 28 units

Hence the length of line segment CD from the given kite is 28 units

Answer: 2 1/6

Step-by-step explanation:

Because the denominators are different, and there are whole numbers involved, then first make the fractions improper.

4 1/2 -> 9/2

6 2/3 -> 20/3

Next, make the denominators the same by multiplying each fraction by the denominator of the other.

9/2 * 3 = 27/6

20/3 * 2 = 40/6

Then you can subtract the numerators because the denominators are the same:

40/6-27/6= 13/6

Then you can convert to a mixed fraction if need be.

Answer:

68°, 82°, and 30°

Step-by-step explanation:

x+x+14+x-38=180

combine like terms

3x-24=180

put variables on one side

3x=204

divide

x=68

substitute

x=68

x+14=82

x-38=30

By using the triangle angle sum theorem, we find that the measures of the angles of the triangle in question are 68 degrees, 82 degrees, and 30 degrees.

This question involves using the fact that the sum of internal angles in any triangle totals 180 degrees. In this triangle, the three angles are given as x, x+14, and x-38. To find the measures of these angles, we set up the below equation:

x + (x+14) + (x−38) = 180

The step above incorporates the triangle angle sum theorem. Now we simplify and solve for 'x':

3x - 24 = 180
3x = 204
x = 68

So the measure of the angles in the triangle are 68 degrees, 82 degrees, and 30 degrees.

The equation of the line is [tex]5x+y-38=0[/tex]

Step-by-step explanation:

The slope is [tex]m=-5[/tex]

Also, the line passes through the points [tex](7,3)[/tex]

To find a line with slope [tex]m=-5[/tex] that passes through the points [tex](7,3)[/tex], let us use the equation of a line with slope that passes through the point is given by [tex](y-y_{1} )=m(x-x_{1} )[/tex] where m is the slope and [tex](x_{1} ,y_{1} )[/tex] are the points [tex](7,3)[/tex].

Thus, substituting the values in the equation of a line, we get,

[tex](y-3)=-5(x-7)[/tex]

Multiplying the term [tex](x-7)[/tex] by -5, we get,

[tex]y-3=-5 x+35[/tex]

Adding both sides by 5x,

[tex]5x+y-3=35[/tex]

Subtracting 35 from both sides of the equation,

[tex]5x+y-38=0[/tex]

Thus, the equation of the line is [tex]5x+y-38=0[/tex]

Answer: [tex]k=\frac{M^t(v-P)}{P}[/tex]

Step-by-step explanation:

Given the following equation provided in the exercise:

[tex]P=\frac{v}{1+kM^{-t}}[/tex]

You can follow these steps in order to solve for "k":

1. You must multiply both sides of the equation by [tex]1+kM^{-t}[/tex]:

[tex](P)(1+kM^{-t})=(\frac{v}{1+kM^{-t}})(1+kM^{-t})\\\\P+PkM^{-t}=v[/tex]

2. The next step is to subtract "P" from both sides of the equation:

[tex]P+PkM^{-t}-(P)=v-(P)\\\\PkM^{-t}=v-P[/tex]

3. Now apply the Negative Exponent Rule, which states that:

[tex]a^{-n}=\frac{1}{a^n}[/tex]

Then:

[tex]\frac{Pk}{M^{t}}=v-P[/tex]

4. Multiply both sides of the equation by [tex]M^t[/tex]:

[tex](M^t)(\frac{Pk}{M^{t}})=(M^t)(v-P)\\\\Pk=M^t(v-P)[/tex]

5. And finally, you must divide both sides of the equation by "P":

[tex]\frac{Pk}P=\frac{M^t(v-P)}{P}\\\\k=\frac{M^t(v-P)}{P}[/tex]

The population density of Hawaii is 109.09 with an area of [tex]1.1 \times 10^4[/tex]square miles and a population of [tex]1.2 \times 10^6[/tex] people.

Given that:

The area of Hawaii is 1.1 × 10^4 square miles

The population  of Hawaii is  1.2 × 10^6 square miles

The population density of Hawaii can be calculated as:

[tex]Population \ density = \dfrac{Number \ of \ people} {land\ area}[/tex]

Substitute the values in the given formula:

[tex]Population \ density = \dfrac{ 1.2 \times 10^6} {1.1 \times 10^4}[/tex]

This can be further solved as:

[tex]Population \ density = \dfrac{ 1.2 \times 10^{(6 -4)}} {1.1}[/tex]

The laws of exponent are used here,

Where,  [tex]\dfrac{x^m}{x^n} = x^{(m-n)[/tex]

This can be solved as:

Population  density = [tex]1.0909 \times10^2[/tex]
