There are 0 unique triangles that can be drawn with the side lengths 4 cm, 5 cm, and 10 cm
How to determine the total number of unique triangles that can be drawn
From the question, we have the following parameters that can be used in our computation:
Side lengths = 4 cm, 5 cm, and 10 cm
According to the triangle inequality theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
So, we have
4 + 5 > 10 --- false
4 + 10 > 5 --- true
5 + 10 > 4 --- true
Since one of the conditions is false, no triangles can be formed using the side lengths

b. Angle A prime B prime C prime.
c. Angle B prime C prime D prime.
d. Angle C prime D prime A prime.ormed to figure A′B′C′D′:
Answer:
a. ∠D'A'B'
Step-by-step explanation:
From the graph it is clear that the transformation doesn't affect the size and shape of the figure ABCD.
Only the coordinates of the points are changed with the length of each side remaining the same.
Hence the corresponding angle values will also remain unaltered.
∴ ∠DAB = ∠D'A'B'
Is a quadratic sequence (2,3,6,11) arithmetic, geometric, or neither?
Answer:
Neither
Step-by-step explanation:
It's neither. The terms do not differ (which means you add the same number to each term) by any constant amount. (Arithmetic)
The terms do not have a common number that you multiply the present term to get the next term. (Geometric)
So this one is neither.
Billy graphed the system of linear equations to find an approximate solution. y =-7/4 x +5/2 y =3/4 x – 3
Answer:
[tex](2.2,-1.35)[/tex]
Step-by-step explanation:
we have
[tex]y=-\frac{7}{4}x+\frac{5}{2}[/tex] ------> equation A
[tex]y=\frac{3}{4}x-3[/tex] ------> equation B
Remember that
The solution of the system of equation is the intersection point both graphs
Using a graphing tool
see the attached figure
The intersection point is [tex](2.2,-1.35)[/tex]
Final answer:
To find the approximate solution to the system of linear equations, set the equations equal to each other, combine like terms, simplify, solve for x, substitute the value of x back into either equation to find y, and simplify further. The approximate solution is x = 3/2 and y = -1/8.
Explanation:
Given the system of linear equations:
y = -7/4 x + 5/2
y = 3/4 x - 3
Set the two equations equal to each other:
-7/4 x + 5/2 = 3/4 x - 3
Combine like terms:
2x + 5 - 14 = 6 - 12
Simplify:
2x - 9 = -6
Add 9 to both sides:
2x = 3
Divide both sides by 2:
x = 3/2
Substitute the value of x back into either equation to find the value of y:
y = -7/4 * (3/2) + 5/2
Simplify:
y = -21/8 + 20/8
Add the fractions:
y = -1/8
Therefore, the approximate solution to the system of linear equations is x = 3/2 and y = -1/8.

i hope its correct
Step-by-step explanation:
which of the following is a correct equation for the line passing through the point -3,2 and having a slope m=2/3 check all that apply
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0 or (0,y))
Since you know m = 2/3, plug it into the equation
y = 2/3x + b
To find "b", plug in the point into the equation (-3,2)
y = 2/3x + b
2 = 2/3(-3) + b
2 = -2 + b
4 = b
y = 2/3x + 4
Point-slope form:
y - y₁ = m(x - x₁)
You know:
m = 2/3
(x₁ , y₁) = (-3,2)
Plug this into the equation:
y - y₁ = m(x - x₁)
y - 2 = 2/3(x - (-3))
y - 2 = 2/3(x + 3)
Answer:
2x-3y = =12
y= 2/3x + 4
y-2 = 2/3 (x+3)

A soccer player ran 180.48 miles in 70.5 days to stay fit. How many miles will he run in 9 days
Final answer:
The soccer player will run 23.04 miles in 9 days.
Explanation:
To find out how many miles the soccer player will run in 9 days, we need to calculate the average number of miles he runs per day. We can do this by dividing the total distance he ran by the number of days.
So, 180.48 miles ÷ 70.5 days = 2.56 miles per day.
Now we can determine how many miles he will run in 9 days by multiplying the average number of miles per day by 9.
So, 2.56 miles per day × 9 days = 23.04 miles.

A bag has 12 red marbles and 6 green marbles. Half of the green marbles are made of plastic. A marble is selected at random from the bag. What is the probability that it is a green, plastic marble? Write your answer as a fraction in simplest form.
Answer:
1/6 is the probability of it being a green plastic marble.
Step-by-step explanation:
Note that there are 18 marbles in all (12 + 6 = 18).
Half of the green marbles (6) are made of plastic: 6/2 = 3
From the information above, we see that 3 green marbles are made of plastic. There are 18 marbles in all.
Divide, and simiplify.
(3/18)/(3/3) = 1/6
1/6 is the probability of it being a green plastic marble.

How do you find a sum of a square root?
You can add two square roots of the numbers if the numbers are the same:
[tex]\sqrt{a}+\sqrt{a}=2\sqrt{a}\\\\n\sqrt{a}+m\sqrt{a}=(n+m)\sqrt{a}\\\\\sqrt{a}+\sqrt{b}=\sqrt{a}+\sqrt{b}[/tex]
Final answer:
To find the sum of square roots, you can add the square roots together if the numbers underneath are the same. If the numbers are different, you cannot simplify them further.
Explanation:
To find the sum of a square root, you need to add the square roots together. However, the numbers under the square roots must be the same. For example, if you have √2 + √2, you can add them to get 2√2. But if you have √2 + √3, you cannot simplify it any further.
Another way to find the sum of square roots is to simplify them using the multiplication property. For example, if you have √2 + 2√2, you can combine them as (1+2)√2 = 3√2.
It is important to note that you can only add square roots with the same number underneath. If the numbers are different, you cannot simplify them further.

which is a solution for 3 > f? f = 7 f = 9 f= 3 f =2?
Answer:
F = 2
Step-by-step explanation: If you want to know which one is a solution, you have to substitute the numbers in for F.
F = 7:
3 > f
3 > 7
This is false because 3 is NOT greater than 7, it is less than 7.
F = 9:
3 > f
3 > 9
This is false because 3 is NOT greater than 9, it is less than 9.
F = 2:
3 > f
3 > 2
This is TRUE because 3 IS greater than 2.

Answer:
D. P = 15 and Q = 15Step-by-step explanation:
Put the values of P and Q to the equation Px - 45 = Qx + 75:
15x - 45 = 15x + 75 subtract 15x from both sides
-45 = 75 FALSE
In other cases, we get some value x.
Example:
A. P = -45 and Q = -75
-45x - 45 = -75x + 75 add 45 to both sides
-45x = -75x + 120 add 75x to both sides
25x = 120 divide both sides by 25
x = 4.8
As the figure shows Elton runs 500 m to point b first then he turns 110 degrees and runs another 350 m to point c how far is the distance from point a to c
Answer:
658.24 m
Step-by-step explanation:
The figure makes a triangle with vertices abc.
Where ab = 500 m
bc = 350 m
The angle abc = 100°
Using the cosine rule we can find the distance ac.
ac² = 500²+350² - 2×500×350×cos100°
= 372,500 - -60,776.86
= 433,276.86
ac = √433,276.86
= 658.24 m

-3x - y = -1
x = 4y + 22
Answer:
x=2
y=-5
Step-by-step explanation:
-3(4y+22)-y=-1
-12y-66-y=-1
-13y-66=-1
-13y=65
y=-5
x=4(-5)+22
x=-20+22
x=2
Answer:
y = 5
x = 2
Step-by-step explanation:
So we know what x is already.
x = 4y + 22
Now we plug that in to the first equation.
-3 ( 4y + 22) - y = -1
Distribute the -3.
-12y - 66 - y = -1
Combined like terms:
-13y - 66 = -1
-13y = 65
Divide -13 on both sides:
y = -5
Now plug your y into the second equation:
x = 4(-5) + 22
x = -20 + 22
Simplify:
x = 2
Check your answer:
-6 - (-5) = -1
2 = -20 + 22
Variables x and y are in direct proportion, and y = 35 when x = 2m. If x = 8m, then y = A) 4.375 B) 8.375 C) 70 D) 140
Answer:
D) 140
Step-by-step explanation:
The equation for direct variation is y= kx
If we know x and y we can solve for k
35 = k*2
Divide each side by 2
35/2 =k
Now the equation for direct variation is
y= 35/2 x
Given x=8 we can substitute in
y = 35/2 * 8
y = 140
Answer: D) 140

I think the sign flips because the negative sign is w/the X.... If it doesn't, sorry 4 being wrong...
The solution to the inequality -4x - 10 ≤ 2 obtained by isolating the variable x is x ≥ -3. This includes all real numbers x that are greater than or equal to -3.
Explanation:Let's solve the inequality -4x - 10 ≤ 2 step-by-step.
Add 10 to each side: -4x - 10 + 10 ≤ 2 + 10 which simplifies to -4x ≤ 12.Next, divide each side by -4: -4x / -4 ≥ 12 / -4. Remember, when you divide or multiply by a negative number, you need to reverse the direction of the inequality sign, so it becomes x ≥ -3.Therefore, the solution to -4x - 10 ≤ 2 is x ≥ -3. This means that for any real number x that is greater than or equal to -3, the inequality -4x - 10 ≤ 2 is true.

What is y = -1/4x +4 written in standard form?
[tex]y = -\frac{1}{4}x +4\ /\cdot4\\4y=-x+16\\x+4y=16\\C[/tex]
Answer:
C) x + 4y = 16
Step-by-step explanation:
The standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers.
As we need all the coefficients to be integers, we have to multiply by 4 on both sides of the equation (that will make the coefficient of x integer). We have to multiply it on both sides because is an equation.
4*y = 4*(-1/4x + 4)
4y = -x + 16
Now we need the x-term to be on the left side of the equation, so we add x on both sides:
x + 4y = -x + 16 + x
x + 4y = 16
Using the distributive property, remove the parentheses
