Let f(x)=3x^2-8 and let g(x)=4x+1. Find the given value f[g(-1)]
lana [24]

Answer:

19

Step-by-step explanation:

given:

f(x)=3x²-8

g(x)=4x+1

g(-1) = 4(-1)+1

g(-1) = -4 + 1

g(-1) = -3

hence

f[g(-1)]

= f(-3)

= 3(-3)²-8

= 3(9) - 8

= 19

Zachary has nickels, dimes and quarters in his piggy bank. He has 58 coins with a total value of $6.50. There are twice as many
kari74 [83]

Answer:

nickel = 16

dimes = 32

quarters = 10

Step-by-step explanation:

Given that,

number of coins Zachery have in his piggy bank = 58

total money Zachery have in his piggy bank = $6.50

Suppose number of nickel = x

               number of dimes = 2x

               number of quarters = y

1 nickel = $0.05

1 dime = $0.10

1 quarter = $0.25

<h3>Equation 1</h3>

x + 2x + y = 58

3x + y = 58

<h3>Equation 2</h3>

x(0.05) + 2x(0.10) + y(0.25) = 6.50

0.05x + 0.2x + 0.25y = 6.50

0.25x + 0.25y = 6.50

y = 58 - 3x

<h3>put value of y in equation 2</h3>

0.25x + 0.25(58 - 3x) = 6.50

0.25x + 14.5 - 0.75x = 6.50

-0.5x = 6.50 - 14.5

-0.5x = -8

x = 16

y = 58 - 3x

y = 58 -3(16)

y =10

number of nickel = x = 16

number of dimes = 2x = 32

number of quarters = y = 10

Find the slope of the line <br> -2/1<br> 1/2<br> -1/2<br> 2/1
natka813 [3]

Answer:

1/2

Step-by-step explanation:

you the x and the y intercepts!

the X intercept is (4,0) and the Y intercept is (0,-2)

and in having those two intercepts, it made solving for the slope a whole lot easier!!!

heres what you do:

<u>-2 - 0  =   -2</u>

0 - 4  =   -4

and that can be simplified down to 1/2 :D

<em>i wasn't quite sure what the numbers you put in the question were, so i just looked at the picture :D hope this helps!!! </em>
