Base pay + (rate * sales) = total pay
b + r(400) = 388
b + r(700) = 454
b = 388 - 400r
now sub into 2nd equation
388 - 400r + 700r = 454
-400r + 700r = 454 - 388
300r = 66
r = 66/300
r = 0.22...22% is the rate
substitute for r
b + 400r = 388
b + 400(0.22) = 388
b + 88 = 388
b = 388 - 88
b = 300
so ur equation is : y = 0.22x + 300
y = 0.22(2600) + 300
y = 572 + 300
y = 872......so her salary when selling $2600 worth of stuff is $872
Answer:
No. It is an obtuse triangle.
Step-by-step explanation:
If c^2>a^2+b^2, then the triangle is obtuse. Since 24^2 + 7^2 is 625, and the square root of 625 is 25, that means 26>25. This proves that the triangle is obtuse.

The answer is C, because those are the points that cross the x-axis.
Answer:
x = 7
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
7x - 6 = 8 + 5x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 5x on both sides: 2x - 6 = 8
- Add 6 to both sides: 2x = 14
- Divide 2 on both sides: x = 7
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 7(7) - 6 = 8 + 5(7)
- Multiply: 49 - 6 = 8 + 35
- Subtract/Add: 43 = 43
Here we see that 43 does indeed equal 43.
∴ x = 7 is a solution of the equation.
