Joan was assigned to graph an absolute value function, but she forgot the function. However, she remembers the following the y-int is (0,-7), the vertex is (3,-1). Help Joan to rewrite the original equation that she was given.
Answer:
f(x)= -2|x-3|-1
(Hi Simran! I just wanted to help you with this question though it might be wrong)
Step-by-step explanation:
f(x) = a|x-h|+k
f(x)= a|x-3|-1
-7 = a |0-3| -1
-7 = a |-3| -1 <-- add to -7
-6 = a |-3|
-6 = 3a
-6/3 = a
-2 = a
-------------------------------------------------------------------------------------
The equation of the absolute value is f(x)= -2|x-3|-1
Evaluate |-6| - |2|.
Answer: 4
Step-by-step explanation: |−6|−|2|
=6−|2|
=6−2
=4

Cindy spent $65.25 on ingredients for blueberry pies and $62.84 on ingredients for cherry pies. Each slice of ple sells for $3.50.
Part A
Write an expression to represent Cindy's profit if she sells b slices of blueberry pie and C slices of cherry ple.
Part B
Cindy sells 24 slices of blueberry ple and 15 slices of cherry ple. The ne
xt day, she sold 26 slices of blueberry ple and 17 slices of cherry pie. What was her total profit?
The expression that represents Cindy's profit is $3.5b - $128.09.
Cindy's total profit is $30.82.
What is profit?Profit is total revenue less total cost. Total revenue is the selling price per unit multiplied by the total units sold.
Profit = total revenue - total cost
($3.50b) - ($65.25 + $62.84)
$3.5b - $128.09
What is Cindy's total profit?Profit for the first day = $3.5(24 + 15) - $128.09
= ($3.5 x 39) - $128.09
= $136.50 - $128.09
=$8.41
Profit for the next day = $3.5(26 + 17) - $128.09
= ($3.5 x 43) - $128.09
= $150.50 - $128.09
= $22.41
Total profit = $22.41 + $8.41 = $30.82

Answer:
A. 200
B. Growth
C. 118%
Step-by-step explanation:
Answer:
Initial population size=200
The function represents a growth
Step-by-step explanation:
Equation to calculate population size after time, t
P(t) = 200(1.18)^t
To find initial population size we will take t = 0
P(0) = 200(1.18)^0
= 200(1)
= 200
To find that function represent growth or decay
P(1) = 200(1.18)^1
= 200(1.18)
= 236
Its means that after a year population increases. Hence, function represent growth.
By what percentage does the population change each year?
(236 - 200 / 200) * 100%
= 235%

LITTERLY HELP ME PLEASEE..... 2/x-4x/2x-3=-2
PLEASEE I INSERTED A PIC
Answer:
x = -3
Step-by-step explanation:
Given expression is,
[tex]\frac{2}{x}- \frac{4x}{2x-3}=-2[/tex]
[tex]\frac{2(2x-3)}{x(2x-3)}-\frac{4x(x)}{x(2x-3)}=-2[/tex]
[tex]\frac{2(2x-3)-4x^{2} }{x(2x-3)}=-2[/tex]
(4x - 6) - 4x² = -2x(2x - 3)
4x - 6 - 4x² = -4x² + 6x
4x - 6 = 6x
6x - 4x = -6
2x = -6
x = -3

the total surface area of a hemisphere is 45
[tex]\pi\p[/tex]
CM square find its volume
Answer:
The volume of the hemisphere
V = 121.33086 cubic centimeter
Step-by-step explanation:
Step(i):-
Given that the total surface area of a hemisphere = 45π cm²
The total surface area of a hemisphere = 3π r²
Equating
3π r² = 45π
[tex]r^{2} = \frac{45}{3} =15[/tex]
r = [tex]\sqrt{15} = 3.87[/tex]
The radius of the sphere 'r' = 3.87
Step(ii):-
The volume of the hemisphere
[tex]V = \frac{2}{3} \pi r^{3}[/tex]
[tex]V = \frac{2}{3} \pi (3.87)^{3}[/tex]
we know that π = 3.14
[tex]V = \frac{2}{3} (3.14) (3.87)^{3}[/tex]
V = 121.33086 cubic centimeter

Need help finding the value of x
Answer:
The value of x is 26.
Step-by-step explanation:
In a triangle, the total angles is 180°. In order to find the value of x, you have to add up all the angles in terms of x and make it equals to 180°
2x + 3x + 50 = 180
5x + 50 = 180
5x = 180 - 50
5x = 130
x = 130 ÷ 5
x = 26
As we know that,
Sum of all angles of triangle = 180°
Given,
Angles are 2x , 3x and 50°
Now,
[tex] \rightarrow \: 2x + 3x + 50 = 180[/tex]
When plus sign goes to another side then,it become minus.
[tex] \rightarrow \: 5x = 180 - 50[/tex]
[tex] \rightarrow \: 5x = 130[/tex]
[tex] \rightarrow \: x = \cancel \dfrac{130}{5} [/tex]
[tex] \rightarrow \: x = 26[/tex]
Hence,the value of x is 26°.
