If f(x) =3x-5 them find values of f(3) and f(-7). please explain step by step​
LenKa [72]

Answer:

f(3) = 4

f(-7) = -26

Step-by-step explanation:

Hi there!

f(x) =3x-5

To find f(3), replace every x with 3:

f(3) =3(3)-5\\f(3) =9-5\\f(3) =4

Therefore, f(3)=4.

f(x) =3x-5

To find f(-7), replace every x with -7:

f(-7) =3(-7)-5\\f(-7) =-21-5\\f(-7) =-26

Therefore, f(-7)=-26.

I hope this helps!

What is the product of the 2 solutions of the equation x^2+3x-21=0
Advocard [28]
X²+3x-21=0

1) we solve this square equation:
x=[-3⁺₋√(9+84)] / 2=(-3⁺₋√93)/2
We have two solutions:
x₁=(-3-√93)/2
x₂=(-3+√93)/2

2) we compute the product of the 2 solutions found.
[(-3-√93)/2][(-3+√93)/2] =(-3-√93)(-3+√93) / 4=
=(9-93)/4=-84/4=-21

Answer: the product of the 2 solutions of this equation is -21

Help I over slept and only have one period to finish this test!!
Blababa [14]

Answer:

68°

Step-by-step explanation:

Okay, so m<8 is on the same plane as m<7 because line <em>q </em>is intersecting line <em>t  </em>and that's supposed to add up to 180° so:

180° - 112° = 68°

So, m<7 = 68°

hope this helps:)

ASAP!!! A proportional relationship is shown in the table below. X: 0 0.3 0.6 0.9 1.2 Y: 0 1 2 3 4 What is the slope of the line
Lera25 [3.4K]
The slope is 3/10, and just graph 2 points ( so like .3,1 and .9,2) and just use Desmos to figure out the line using the y=3/10x+3.64 and just type it in
