Answer:
(-4,9)
Step-by-step explanation:
substitute the given value for y into the first equation
x-5(-2x+1)=-49
distribute
x+10x-5=-49
add like terms
11x-5=-49
add 5 to both sides
11x=-44
divide both sides by 11
x=-4
now plug x into into the second equation
y=-2(-4)+1
y=8+1
add like terms
y=9
Select all the equations where x = 3 is a solution.

What type of solutions to quadratic equations can be solved by factoring and using the zero product property?
Answer:
The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0. When the product of factors equals zero, one or more of the factors must also equal zero. Once the polynomial is factored, set each factor equal to zero and solve them separately.

y = 2x + 4
y = –2x + 4
y = 2x – 4
y = –2x – 4
Answer:
y=-2x-4
Step-by-step explanation:
The slope has a Y-intercept at the -4, which narrows the choices down to 2. Since the slope is leaning left, it's a negative, which will make the answer to this y=-2x-4

Given the expression (−2x2)(3x)(x), Jose says that different products occur if the order of the quantities being multiplied changes. Is Jose correct? Explain.
Answer:
Jose is incorrect.
Step-by-step explanation:
Using the communitive property, you can rearrange (-2x2), (3x), and (x) in the problem and get the same product. You can rearrange it to (3x)(x)(-2x2). You can rearrange it to (3x)(-2x2)(x). Now matter where you rearrange them, the equation will always have the same product.
