Answer:
x = 2 | y = 3. ( 2,3 )
Step-by-step explanation:
2(3x + 3y = 15)
6x + 6y = 30
3(4x + 2y = 14)
12x + 6y = 42
- 6x. -6y. -30
6x = 12
÷ 6. ÷6
x = 2
3x + 3y = 15
3(2) + 3y = 15
6 + 3y = 15
-6. -6
3y = 9
÷3. ÷3
y = 3

Answer: - 235
<u>Step-by-step explanation:</u>
f(x) = -3x² + 13x + 3
f(-7) = -3(-7)² + 13(-7) + 3
= -3(49) - 91 + 3
= -147 - 88
= -235
Answer:
The answer is y=1/3x-1
Step-by-step explanation:
m=1/3
y-y=m(x-x1)
y-(-1)=1/3(x-0)
y+1=1/3x-0
-1 -1
y=1/3x-1
(1, 1) the slope is 2 and slopes can be read the easiest when expressed as a fraction (2/1) when the numerator (2) expresses how many digits you move the point up and the denominator (1) expresses how many points you move right
