Use f(x)=-4x+1, g(x)=x^2-8x+21, and h(x)=║9-3x║ for these equations.
Find g(-5)
Find g(x+4)
If f(x)=53, find x.

Answers

Answer 1

Step-by-step explanation:

For each problem, plug in the values, then simplify.

g(x) = x² − 8x + 21

g(-5) = (-5)² − 8(-5) + 21

g(-5) = 25 + 40 + 21

g(-5) = 86

g(x) = x² − 8x + 21

g(x+4) = (x+4)² − 8(x+4) + 21

g(x+4) = x² + 8x + 16 − 8x − 32 + 21

g(x+4) = x² + 5

f(x) = -4x + 1

53 = -4x + 1

52 = -4x

x = -13

CAYB is a quadrilateral

CA= 3a
CB= 6b
BY= 5a-b

X is the point on AB such that AX:XB= 1:2

Prove that CX = 2/5 CY

Answers

Answer:

see explanation

Step-by-step explanation:

CY = CB + BY

     = 6b + 5a - b

     = 5a + 5b

---------------------

CX = CA + AX

     = CA + [tex]\frac{1}{3}[/tex] AB , find AB

AB = AC + CB

     = - 3a + 6b

     = 6b - 3a

Thus

CX = CA  + [tex]\frac{1}{3}[/tex] AB

      = 3a + [tex]\frac{1}{3}[/tex](6b - 3a)

      = 3a + 2b - a

      = 2a + 2b

---------------------

and

[tex]\frac{2}{5}[/tex] CY

= [tex]\frac{2}{5}[/tex] (5a + 5b)

= 2a + 2b = CX

Hence CX = [tex]\frac{2}{5}[/tex] CY ⇒ Proven

, find the length of QS and TV.

Answers

The length of the segment QS is 8 units and the length of the segment TV is 8 units and this can be determined by using similar triangle properties.

Given :

Triangle QRS is congruent to triangle TUV.The length of the segment QS is (3v + 2).The length of the segment TV is (7v - 6).

The following steps can be used in order to determine the length of QS and TV:

Step 1 - According to the given data, the triangle QRS is congruent to triangle TUV.

Step 2 - So, the length of the segment QS is equal to the length of the segment TV.

QS = TV

Step 3 - Substitute the values of QS and TV in the above expression.

3v + 2 = 7v - 6

7v - 3v = 6 + 2

4v = 8

v = 2

Step 4 - The length of the segment QS and TV is:

QS = 3(2) + 2 = 6 + 2

QS = 8

TV = 7(2) - 6 = 14 - 6

TV = 8
