Answer:
(31, 2); Substitution.
Step-by-step explanation:
x - 3y = 25
Use SUBSTITUTION by setting everything in the above equation equal to x...
x = 3y + 25
2(3y +25) + y = 64
6y + 50 + y = 64
7y + 50 (-50) = 64 (-50)
7y = 14
y = 2
Then, substitute y = 2 into the original equation.
x - 3(2) = 25
x - 6 = 25
x = 31
(x, y) = (31, 2)

Ok, so you would want to simplify both sides of the equation
(-1/3)(-12) + (1/3)(-12c)=-20 (here you distribute)
4+4c=-20
Then, subtract 4 from both sides
4c+4-4=-20-4
4c=-24
Then divide both sides by 4
4c/4=-24/4
c=-6
Find the area of the shape shown below
Answer:
12 units squared
Step-by-step explanation:
You need to find the area of each individual shape, and then add them together. The area of the square is 4 units squared. The triangle on the left is two units squared (base times height, divided by two,) and the area of the triangle on the left is 6. Add them all together, and you get 12 units squared.
Answer:
24
area is round the outside times them together and you will get the inside

What are the steps for 625 to the power of 3/4
Answer:
125
Step-by-step explanation:
note that
625 = [tex]5^{4}[/tex]
Using the rule of exponents
[tex](a^{m}) ^{n}[/tex] ⇔ [tex]a^{mn}[/tex]
Then
[tex](5^{4}) ^{\frac{3}{4} }[/tex]
= 5³
= 125

calculate the coefficient b in the function f (x) = - x + b for which it holds that the graph passes through the point (-1,3)
Need if fast!
Answer:
b = 2
Step-by-step explanation:
For the graph to pass through the point, we have it that the coordinates of the point will work in the equation of the line
Hence, by substituting the x value, we can get the y value and by substituting the y value, we can get the x value
where f(x) is same as y in this case
Thus, we have it that;
3 = -(-1) + b
3 = 1 + b
b = 3-1
b = 2

x^(2)-8x=-7
Please show work.
Answer:
This equation has two solutions.
1 solution is: x - 1
Solution #2 is : x - 7
Step-by-step explanation:
1. Move the constant to the left. We end up with x^2 - 8x +7 = 0
2. Rewrite the expression: x^2 - x - 7x + 7 = 0
3. Factor the expressions: x * (x-1) -7(x-1) = 0
4. Separate into possible cases : (x-1) * (x-7) = 0
5. Solve the equation(s): x-1 = 0
x-7 = 0
6. Possible solutions are as follows: x-1 OR x-7
