Answer:
The answer to your question is: The second option
Step-by-step explanation:
Points A (3 , 7) B (5, 11)
slope = m = (y2 - y1) / (x2 - x1)
m = (11 - 7) / (5 - 3)
m = 4 / 2 = 2
equation if the line
(y - y1) = m(x - x1)
(y - 7) = 2(x - 3) Answer
Three values that would make this true:
5
4

Answer:
Step-by-step explanation:
the triangle with 9 as a side is a 45,45, 90 triangle. so there for x and 9 are congruent. Thus. x=9
Answer:
y = 112
Step-by-step explanation:
If y varies directly as the square of x
mathematically;
y ∝ x²
y = kx² where 'k' is the constant of proportionality
let u know the value of k for this equation by making k the subject of the formular from y = kx²
divide both sides by x²
k = y / x²
given that y = 567 x = 9
k = 567/(9)²
k = 567/81
k = 7
now to get the value of y when x = 4
from the equation conneting x, y,
y = kx²
y = 7 × (4)²
y = 7 × 16
y = 112
