Answer:
it took them 18 minutes to earn $500
Step-by-step explanation:
Step 1: Flip the equation.
−250x+5000=500
Step 2: Subtract 5000 from both sides.
−250x+5000−5000=500−5000
−250x=−4500
Step 3: Divide both sides by -250.
−250x
−250
=
−4500

a) z(z+11) =520
b) z(z - 11) = 520
c) z(11 - 2) = 520
d) - 112 - 520 = 0
e) 2 + 112 - 520 = 0

Answer:
z*(z - 3) = 520
Step-by-step explanation:
Use the following representations:
Width: W
Length: L = W + 3, or W = L - 3
Area = L*W = L*(L - 3) = 520
Equation b) is the correct one: z*(z - 3) = 520

How would you graph this correctly onto a graph?
Answer:
Here is how you graph your equations correctly :D
Step-by-step explanation:
Graph y > x − 2.
Use the slope-intercept form to find the slope and y-intercept.
Slope: 1
y-intercept: (0, -2)
Graph a dashed line, then shade the area above the boundary line since y is greater than x − 2 .
y > x - 2
Graphy < −4x + 2.
Use the slope-intercept form to find the slope and y-intercept.
Slope: -4
y-intercept: (0, 2)
Graph a dashed line, then shade the area below the boundary line since y is less than − 4 x + 2 .
y < -4x + 2
Plot each graph on the same coordinate system.
y > x - 2
Y < -4x + 2
I hope this helps.
Find the slope of the line that goes through (2, -1) and (6, 1).
Answer:
Slope= y=(1/2)x-2
Step-by-step explanation:
Answer:
you would use y^1-y^2/x^1-x^2
so you would subtract 6-(-1) , it would be 7
then subtract 1-2 , it would be -1
so your answer is 7/-1
You have decided to cash in all of the coins you have been saving for the summer. In total you have $7.20. You only have dimes and quarters, and you know that you have twice as many dimes as you do quarters. How many quarters do you have in total? How many dimes? (HINT: think about what you know of dimes and quarters!)
Answer:
The number of quarters in total = 16 quarters
The number dimes = 32 dimes
Step-by-step explanation:
The given information are;
The total amount of money in held = $7.20
The denomination of the money held = Dimes and quarters
The number dimes = 2 × The number of quarters
Given that a dime = 10 cents = $0.1
A dollar = 25 cents = $0.25
Let the number of quarters in the sum of money = X
Therefore, we have;
X × $0.25 + 2 × X × $0.1 = $7.20
X × $0.25 + X × $0.2 = $7.20
X × $0.45 = $7.20
X = $7.20/$0.45 = 16
Therefore, the number of quarters = 16
The number of quarters in total = 16 quarters
The number dimes = 2 × The number of quarters = 2 × 16 = 32 dimes
The number dimes = 32 dimes.

What is the inverse of the function f(x)=1/9x+2
[tex]f(x) = \frac{1}{9}x + 2 \\ [/tex]
[tex]y = \frac{1}{9}x + 2 \\ [/tex]
Subtract the sides of the equation minus 2
[tex]y - 2 = \frac{1}{9}x \\ [/tex]
Multiply the sides of the equation by 9
[tex]9(y - 2) = x[/tex]
[tex]9y - 18 = x[/tex]
So ;
[tex] {f}^{ - 1}(x) = 9x - 18 [/tex]

13x < 6(3x – 4) – 6
show work please
Answer:
x > 6
Step-by-step explanation:
Step 1: Write equation
13x < 6(3x - 4) - 6
Step 2: Solve for x
Distribute 6: 13x < 18x - 24 - 6Combine like terms: 13x < 18x - 30Subtract 13x on both sides: 0 < 5x - 30Add 30 to both sides: 30 < 5xDivide both sides by 5: 6 < xRewrite: x > 6if f(x) = 3x2 + 10, what is f( - 7)?
The value of function f(-7) is 157.
What is a function?Functions have the property that each input is related to exactly one output. The function defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
For the given situation,
The function is f(x) = 3 x^2 + 10
Then f( - 7) becomes,
⇒ [tex]f(-7)=3(-7 )^{2} +10[/tex]
⇒ [tex]f(-7)=147+10[/tex]
⇒ [tex]f(-7)=157[/tex]
Hence we can conclude that the value of function f(-7) is 157.
