V = 5x + 2y
x= 3
y=-4
a) Work out the value of V
b) Expand 3p(p + 5)
c) Solve 4(k - 6) = 20
Answer:
a.7
b.
[tex]3 {p }^{2} + 15p[/tex]
c.k=11
Step-by-step explanation:
a.V=5x + 2y ,x=3,y= -4
V=5(3)+2(-4)
=15+(-8)
=15-8
=7
b.3p(p + 5)
=
[tex]3 {p}^{2} + 15p [/tex]
c.4(k-6)=20
4k-24=20
4k-24+24=20+24
4k=44
4k/4=44/4
k=11
hope it's helpful ❤❤❤❤
THANK YOU.

Answer:
We conclude that:
h(f(-1)) = -2
∴ option D i.e. -2 is correct.
Step-by-step explanation:
Given
f(x) = 4x² - 1
g(x) = 1/2x + 5
h(x) = 2(x - 4)³
To determine
h(f(-1)) = ?
In order to determine h(f(-1)) first we need to determine f(-1).
substitute x = -1 in the function f(x) = 4x² - 1
f(-1) = 4(-1)² - 1
f(-1) = 4(1) - 1
f(-1) = 4-1
f(-1) = 3
so
h(f(-1)) = h(3)
now substitute h = 3 in the function h(x) = 2(x - 4)³
h(x) = 2(x - 4)³
h(3) = 2(3 - 4)³
h(3) = 2(-1)³
h(3) = 2(-1)
h(3) = -2
Thus,
h(f(-1)) = h(3) = -2
Hence, we conclude that:
h(f(-1)) = -2
∴ option D i.e. -2 is correct.

1. Sarah and Maya both need notebooks and pencils. The equation that represents Sarah's
purchases is y = 13- 3x. The equation that represents Maya's purchases is y = 7 -x. If y
represents the price of notebooks, and x represents the price of pencils, what are the prices of
the notebooks and pencils?
a) pencils: $4 notebook: $3 go to card 4
b) pencils: $6 notebook: $1 go to card 3
c) pencils: $3 notebook: $4 go to card 5
d) pencils: $1 notebook: $6 go to card 7
e) pencils: $4 notebook: $4 go to card 2
Step-by-step explanation:
We have y = 13 - 3x and y = 7 - x.
=> 13 - 3x = 7 - x
=> 2x = 6, x = 3.
Then y = 7 - (3), y = 4.
Hence the price of a pencil is $3 and the price of a notebook is $4. (C)
answer is c) pencils: $3 notebook: $4 go to card 5

Find the x- and y-intercepts of the graph of the linear equation 3x+6y=2.
Answer:
x intercepts(8,0)
y intercepts (0,-4)
Answer:
x=2/3 y=1/3
Step-by-step explanation:
3x+6y=2 get rid of 6y and put down 3x=2
Do 2 divided by 3x and get an answer of 2/3 x=2/3
----------------------------------------------------------------------------------
3x+6y=2 get rid of 3x and put down 6y=2
Do 2 divided by 6y and get an answer of 1/3 y=1/3

1. A plumber charges $50 for a house call in addition to $80
per hour worked. Which equation represents y, the total cost
for x, hours worked?
Answer:
Step-by-step explanation:
Since the plumber charges $50 regardless of how many hours he works, then the equation must be 50 + ....
Since the plumber charges $80 for each hour, then the equation will be y = 50 + 80x.

solve for x in the following question 2x - 3 = 1
Answer:
x = 2
Step-by-step explanation:
2x-3 = 1
use addition property of equality (add 3 to each side to keep balance)
2x = 4
use division property of equality (divide both sides by 2)
4/2 = 2
so,
x = 2
