Point-slope
y - y1 = m(x - x1)
y - 3 = -12(x - 5)
Answer:
x=13
Step-by-step explanation:
x+4 = 17
Subtract 4 from each side
x+4-4=17-4
x = 13

Answer:
x≈ -4.71
Step-by-step explanation:
7(x+6)=9
Distribute the 7 into the parenthesis.
7x+ 7(6)= 9
Multiply the numbers.
7x+ 42= 9
Subtract from both sides.
7x+42= 9
-42 -42
Now, divide to both sides.
<u> 7x</u>= <u>-33</u>

x= -4.71428571429
x≈ -4.71
Answer:
below
Step-by-step explanation:
You've been asked to use specific x-values. Simply replace the x in the equation for each of your x-values then graph.
first equation!!
(x,y)
y=-2x+5
x-value: -2
y=-2(-2)+5
y=4+5
y=9
(-2, 9)
x-value: -1
y=-2(-1)+5
y=2+5
y=7
(-1, 7)
x-value: 0
y=-2(0)+5
y=0+5
(0, 5)
x-value: 1
y=-2(1)+5
y=-2+5
y=3
(1, 3)
x-value: 2
y=-2(2)+5
y=-4+5
y=1
(2, 1)
second equation :)
(x,y)
y=x^2 +2
x-value: -2
y=-2^2 +2
y=4+2
y=6
(-2, 6)
x-value: -1
y=-1^2 +2
y=1+2
y=3
