Answer:
x=5
Explanation;
y=4 is a horizontal line, and we know this because all we have is the y intercept; 4 (the y-intercept is the point on the line that intercepts the y axis) There is also no x value. This is the equation for a horizontal line:
y=b
B is the y-intercept.
A line perpendicular to a horizontal line would be a vertical line. This is the equation for a vertical line:
x=d
D is the x-intercept (the point on the line that intercepts the x axis)
So to answer the question, we just need to plug the x value of the point (5,2) into x=d.
(5,2)-> 5 is the x coordinate
Therefore, x=5
I hope this helps! Please comment if you have any questions.
Answer:
The cost per square inch of the pie is $0.111 or 11 cents
Step-by-step explanation:
The shape of a pie is circular.
The area of a circle (pie) = πr²
From the question ,
Diameter = 12 inches
Radius = Diameter/2
Radius = 12 inches/2
Radius = 6 inches.
Hence, the area of the pie = π × 6²
= 113.09733553 square inches
A pie costs $12.55
The cost per square inches of the pie is calculated as:
113.09733553 square inches = $12.55
1 square inch = $x
Cross Multiply
113.09733553x = $12.55
x = $12.55/113.09733553
x = $0.1109663631
Approximately
x = $0.111
Therefore, the cost per square inch of the pie is $0.111 or 11 cents

Answer:
4
Step-by-step explanation:
∛64 = ∛(4³) = 4
_____
The real root when the root index is odd will have the same sign as the value whose root it is. 64 is positive, so the real cube root will be positive.
Answer:
Step-by-step explanation:
1. Interchange x and y. We get: x = y^2 - 5
2. Solve for y: y^2 = x + 5, so that y = ±√(x + 5)
#13 is 17
