Let h(x) = x*2 + kw - 8. If h(-1) = -5, what is the value of h(4)?
Help
Answer:
h(4) = 0
Step-by-step explanation:
Hoping its ' kx '
[tex]h(x) = x^2 + kx -8 \\\\h(-1) = (-1)^2 + k(-1) - 8\\\\-5 = 1 - k -8\\\\-5 = -k -7\\\\-5 + 7 = -k\\\\2 = -k\\-2 = k[/tex]
Now we have k = -2. We will find h(4).
[tex]h(4) = (4)^2 + (-2)(4) - 8 = 16 -8 - 8 = 0[/tex]
Answer:
h(4) = 0
Step-by-step explanation:
GIVEN :-
A quadratic function h(x) = x² + kx - 8h(-1) = -5TO FIND :-
Value of h(4)SOLUTION :-
To find the value of h(4) , you need to find 'k' first by using the given facts.
[tex]h(-1) = (-1)^2 + k(-1) - 8 = -5[/tex]
[tex]=> 1 - k - 8 = -5[/tex]
[tex]=> -k - 7 = -5[/tex]
Add both the sides by 7.[tex]=> -k - 7 + 7 = -5 + 7[/tex]
[tex]=> -k = 2[/tex]
Multiply both the sides by -1.[tex]=> -k(-1) = 2(-1)[/tex]
[tex]=> k = -2[/tex]
Putting the value of k,
[tex]h(4) = (4)^2 + (-2)(4) - 8[/tex]
[tex]= 16 - 8 - 8[/tex]
[tex]= 16 - 16[/tex]
[tex]= 0[/tex]

Answer:
x = 4 , y = -1
Step-by-step explanation:
x - 3y = 7 -- (1)
3x - 3y = 15 -- (2)
Rewriting (1), x = 3y + 7 -- (1)'
Substituting (1)' into (2),
3 ( 3y + 7 ) - 3y = 15
9y + 21 - 3y = 15
6y = -6
y = -1 -- (3)
Substituting (3) into (1),
x - 3 ( - 1 ) = 7
x + 3 = 7
x = 4 -- (4)
According to (3) and (4),
x = 4 , y = -1

Answer and Step-by-step explanation:
For the first one, x is equal to 61 (180 - 63 - 56 = 61)
and y = 4
51 = 12y + 3
48 = 12y
y = 4
For the second one,
x = 11
11x - 4 = 117
11x = 121
x = 11
y = 5
17y - 8 = 12 + 13y

pair if trousers for 75 cedis and sold at 80 cedis. calculate the percentage profit
Answer:
6.7%
Step-by-step explanation:
cost: 75 cedis
sale price: 80 cedis
amount of profit: 80 cedis - 75 cedis = 5 cedis
Now we find what percent 5 cedis is of 75 cedis.
percent = part/whole * 100%
percent = 5/75 * 100%
percent = 0.06666 * 100%
percent = 6.6666%
percent = 6.7%
Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures created by the intersecting lines? Explain.
Answer:
If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.

PLZZZZZ HELP ME! The volume of a suitcase is 4,331.25 inches. The length of the suitcase is 22.5 inches inches and the width is 19.25 inches. What is the height? Show your work.
Answer: 10 inches.
Step-by-step explanation:
v=l*w*h
Let’s plug in your numbers:
4,331.25=22.5*19.25*h
Let’s simplify it.
4,331.25=433.125*h
Then divide both sides by 433.125 (.125=1/8 by the way).
10=h

Solve 3x+8=2x+21
Full expansion
Answer:
x = 13
Step-by-step explanation:
3x + 8 = 2x + 21
shift the numbers to make them like terms . Here shift 2x to left hand side when u shift positive becomes negative 2x . and shift positive 8 to right hand side then it become negative 8
3x - 2x = 21 - 8
subtract like terms
x = 13

Jesse has reached 16% of his weekly reading time goal so far this week. If he has read for a total of
32 minutes this week, what is his weekly reading time goal in minutes?
x = time goal
16% = .16
.16 x = 32
x = 32/.16 = ___________ minutes
Jesse' weekly reading time is an illustration of ratio and proportion.
Jesse' weekly reading time is 200 minutes
Represent the reading time with x.
16% of his weekly reading time is given as 32 minutes
This is represented using the following equation
[tex]16 \% \times x = 32[/tex]
Express 16% as decimal
[tex]0.16\times x = 32[/tex]
Divide both sides by 0.16
[tex]x = 32/0.16[/tex]
[tex]x = 200[/tex]
Hence, Jesse' weekly reading time is 200 minutes
