Answer:

I will solve your system by substitution.

y=2;2x+y=8

Step: Solvey=2for y:

Step: Substitute2foryin2x+y=8:

2x+y=8

2x+2=8

2x+2+−2=8+−2(Add -2 to both sides)

2x=6

2x

2

=

6

2

(Divide both sides by 2)

x=3

Answer:

<u>x=3 and y=2</u>

Which of the following represents "the square of the sum of a number and 4 is 36"?
Temka [501]
Lets write the information as an equation, and name x the number unknown:
(x + 4)^2 = 36
that is:
the sum of a number and 4: (x + 4)
then, the square of <span>the sum of a number and 4: (x + 4)^2
so we have:
</span>(x + 4)^2<span> = 36
</span>to solve we calculate square root to both sides of the equation:
(x + 4)<span> = 6
</span>then we solve for x:
x = 6 - 4
x = 2
so the unknown number is 2

With that in mind, the m value is -5 and the b value is 4

Thus, the slope is -5, and the y-intercept is (0,4)

Hello:

the equation is : y = ax+b

the slope is a : a= 2/3

calculate : b

the line that passes through the point (3,-5)  means : - 5 = 2/3 (3)+b

so : b = -7
