Answer:
The first one
Step-by-step explanation:
Answer:
This is curve sketching which is used in math
Step-by-step explanation:
we can see a graph plotting with the equation...of all sides
First square both sides to get:
c + 22 = (c + 2)^2
or
c + 22 = c^2 + 4c + 4
Move the terms on the left side to the right side:
c^2 + 3c - 18 = 0
Factor to get:
(c + 6) * (c - 3) = 0.
The solutions are c = -6 and c = 3.
Check to see if these answers work by plugging them into the original equation:
c = -6:
sqrt (-6 + 22) ?= -6 + 2
But, -6 + 2 is a negative number, and you can't get a negative from a square root. So, -6 is extraneous.
c = 3:
sqrt (3 + 22) ?= 3 + 2
5 = 5. So, 3 works.
The answer is: B
y = m
x + b
.
y = 6
x − 7
Hope this helped!
Answer:
x = 6.125
Step-by-step explanation:
y = -2 + 34
so
-2x + 34 = 6x - 15
<u>+2x +2x </u>
34 = 8x - 15
<u>+15 +15</u>
49 = 8x
<em><u>x = 6.125</u></em>
plz mark as brianliest if correct!!!
