Answer:
37. {-1, -1}.
Step-by-step explanation:
I'll solve the first one . The other can be solved in a similar way. We can use the method of elimination.
x1 - x2 = 0
3x1 - 2x2 = -1
We can multiply the first equation by -2. We then have an equation containing + 2x2 so when we add this to the second equation the 2x2 will be eliminated
So the first equation becomes:
-2x1 + 2x2 = 0 Bring down the second equation:
3x1 - 2x2 = -1 Now adding, we get:
x1 + 0 = -1
so x1 = -1.
Now we substitute this value of x1 in the original first equation:
-1 - x2 = 0
-1 = x2
x2 = -1.
So the solution set is {-1, -1}.
If there are more than 2 equations you can use a combination of substitutions and eliminations.
7,500 plus the commision is 525 now you add it to the 7,500 that will leave you with 8,025 now you subtract it from 185,000 so the answer will be 176,975
I'm glad if it helps :)
Slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.
First, find slope using the given coordinates. Formula for slope: y₁ - y₂ / x₁ - x₂.
Our coordinates are (-2, 5) and (2, -7). Plug them in and simplify.
5 - (-7) / -2 - 2
5 + 7 / -4
12/-4
-3
The slope is -3. The equation becomes y = -3x + b.
To find b, plug an (x, y) coordinate on the line in for x and y in the equation and solve. I'll use (-2, 5)
y = -3x + b
5 = -3(-2) + b
5 = 6 + b
-1 = b
The y-intercept is (0, -1). The equation can now be completed!

Answer:
The pre-tax price of "smart fabric" warm-ups is $745 .
Step-by-step explanation:
Let us assume that the pre-tax price of the "smart fabric" warm-ups be x .
As given
arold paid 5% in sales tax on his new "smart fabric" warm-ups.
if harnold paid 37.25 in sales tax on the warm ups .
5% is written in the decimal form .
= 0.05
Equations becomes
0.05 × x = 37.25
0.05x = 37.25
x = $745
Therefore the pre-tax price of "smart fabric" warm-ups is $745 .
