Answer:
Step-by-step explanation:
Given the expression: P= I + HB
Where:
- P = cost of the phone Liam is saving for.
- I = amount of money he started with.
- H = number of hours he babysits
- B = hourly rate for babysitting.
We want to find an expression for H, the number of hours Liam will need to babysit to save enough money for a cell phone.
Our goal is to isolate the variable H in the expression P= I + HB.
P= I + HB
Subtract I from both sides
P-I=I-I+HB
HB=P-I
Divide both sides by B
Answer:

- Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 64
Hypotenuse <em>c</em> = 80
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: x² + 64² = 80²
- Isolate <em>x</em> term: x² = 80² - 64²
- Exponents: x² = 6400 - 4096
- Subtract: x² = 2304
- Isolate <em>x</em>: x = √2304
- Evaluate: x = 48
The slope of a function is the ratio of the rise (y2 - y1) and the run (x2-x1) of a function, In this case the slope would be (1 - 0) / (1-0) = 1. The y-intercept would be the y value when x is zero. From the table we see this will have a value of zero. The equation for this function would be y = x. We use the said equation to fill the blanks in the table.
The answer is 16/10 = 40/25
You divided 16 by 40 to see what you need to multiply 16 to get 40. When I did that I got 2.5. So I did that to the 10 and got 25 minutes. Hope this makes sense
Answer:
no solution
Step-by-step explanation:
6x - 3y = 7 → (1)
- 2x + y = - 8 → (2)
multiplying (2) by 3 and adding to (1) eliminates the variables
- 6x + 3y = - 24 → (3)
add (1) and (3) term by term
0 + 0 = - 17
0 = - 17 ← false statement
This indicates the system has no solution
