Answer:
y = -5x + 15
Step-by-step explanation:
We'll look for a linear function of the form y = mx + b, where m is the slope and b is the y-intercept.
We can determine a slope from the two given points by calculating a Rise/Run. Starting at (2,5) and going to (3,0):
Rise = (0 - 5) = -5
Run = (3-2) = 1
Rise/Run = Slope, m) = -(5/1) or -5
Now we have y = -5x + b
To find b, enter either of the two points and solve for b. I'll use (3,0), because I know my zero multiplication and addition tables by heart.
y = -5x + b
0 = -5(3) + b
b = 15
The equation becomes <u>y = -5x + 15</u>

Answer: x = 10
Explanation:
Line A is parallel to line B only when the corresponding angles 4x and 3x+10 are congruent
4x = 3x+10
4x-3x = 10
x = 10
Your answer is the last option, 7 or 12.
We can write this question as an equation, if we call the number ‘x’:
(x - 9)² = x - 3
Then we can expand the bracket and solve for x:
x² - 18x + 81 = x - 3
x² - 19x + 84 = 0
(x - 7)(x - 12) = 0
x = 7 or x = 12
The factorisation is a bit difficult so you could also use the quadratic formula to get to the same answer.
