Slope=change in y/change in x
so
from (-4-2) to (-2,-10)
change in y is from -2 to -10, that is -8 change
change in x is from -4 to -2 which is 2 change
-8/2=-4
slope is -4
B
realk way
for
(x1,y1) and (x2,y2)
slope is (y2-y1)/(x2-x1)
so
(-4,-2) and (-2,-10)
slope=(-10-(-2))/(-2-(-4))=(-10+2)/(-2+4)=-8/2=-4
B is answer
Answer: EBF
Explanation: The alternate interior angle is the other interior angle made by a transversal and two parallel lines
Line Segment EB is the transversal
Answer:
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one
<em>For the graph below, what should the domain be so that the function is at least 200? graph of y equals minus 2 times the square of x plus 30 times x plus 200
</em>
My answer:
Given the above information, we have:
To make the function is at least 200, it means that:
≥ 200
<=> ≥ 0
<=> x(-2x+30) ≥ 0
This is the product of two numbers hence would be positive only if either both are positive or both are negative
x ≥ 0 and (-2x+30) ≥ 0
<=> 0 ≤ x ≤ 15
Then we get
This is inconsistent as a value cannot be less than 0 and greater than 15
=> our correct answer is
Hope it will find you well.

Answer:
x = 49
Step-by-step explanation:
This is an inverse relationship and it implies that, an increase in the value of one variable results in a subsequent decrease in the value of another variable.
Given the mathematical expression and data;
y = 1/√x
y = 7 and x = 64
First of all, we would find the constant of proportionality, k;
y = k/√x
7 = k/√64
7 = k/8
k = 7 * 8
Constant, k = 56
Now, to find the value of x when y = 8
y = k/√x
Substituting the values, we have;
8 = 56/√x
Cross-multiplying, we have;
8 * √x = 56
√x = 56/8
√x = 7
Taking the square of both sides, we have;
(√x)² = 7²
x = 49
