Given f(x)=3x-1 and g(x)=2-3, for which value of g(x)=f(2)?

1 answer:

6 0

We have, by function notation, that

f(2)=3(2)=5

now we have
2x-3=5
2x=8
x=4

So the answer to this is 4
Hope this helped :)
Have a great day

Increase 2850 by 18%

faust18 [17]

3363 it is. That is the answer. The problem would be "2850 + 18%" right. Because that's what I did.

I need help ASAP!!!!!

ycow [4]

Input Data :

Point 1 ( x A , y A ) = (-6, -2)

Point 2 ( x B , y B ) = (1, -6)

Objective :

Find the distance between two given points on a line.

Formula :

Distance between two points = √ ( x B − x A )2 + ( y B − y A ) 2

Solution :

Distance between two points = √ ( 1 - -6 ) 2 + ( − 6 − − 2 ) 2

= √ 7 2 + ( − 4 ) 2

= √ 49 + 16

= √ 65 = 8.0623

Distance between points (-6, -2) and (1, -6) is 8.0623

Or 8.

Best of luck!!

A, B, and C are midpoints of ∆XYZ. What is the length of cy

iogann1982 [59]

Answer:

$XY=36\ units$

Step-by-step explanation:

The correct question is

A, B, and C are midpoints of ∆XYZ. What is the length of XY

we know that

The Midpoint Theorem states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side

step 1

Find the length of YZ

$AB=\frac{1}{2}YZ$

we have

$AB=24\ units$

substitute

$24=\frac{1}{2}YZ$

solve for YZ

$YZ=48\ units$

step 2

Find the length of XY

Applying Pythagoras Theorem in the right triangle XYZ

$XZ^2=XY^2+YZ^2$

substitute the given values

$60^2=XY^2+48^2$

solve for XY

$3,600=XY^2+2,304$

$XY^2=3,600-2,304$

$XY^2=1,296$

$XY=36\ units$

Applying the Midpoint Theorem

$BC=\frac{1}{2}XY$ -----> $BC=\frac{1}{2}(36)=18\ units$

$AC=\frac{1}{2}XZ$ -----> $AC=\frac{1}{2}(60)=30\ units$
