Good evening ,

______

Answer:

None of them is correct.

___________________

Step-by-step explanation

We have to solve the equation:

Which ordered pair represents the y-intercept of the graph of the equation y=-5x+6?
Lostsunrise [7]

Answer: B

Step-by-step explanation:

The y-intercept is the number that is a constant. It is the "b" in y=mx+b. The y-intercept is the point on the y-axis. That means the x-coordinate is 0. With this information, we can automatically eliminate C and D.

Since we know y-intercept is the "b" on y=mx+b, we know that 6 is the "b" in the given equation. Therefore, B is the right answer.

For a homework question, Linda is asked to rewrite the expression (x3⋅x)2 ( x 3 ⋅ x ) 2 in the form xk. x k . Linda claims that
andre [41]

Answer:

k=8

Step-by-step explanation:

Question says that given expression is \left(x^3\cdot x\right)^2

Now we need to rewrite that expression in form of x^k.

To do that we need to simplify given problem \left(x^3\cdot x\right)^2.

x is same as x^1

=\left(x^3\cdot x^1\right)^2

we can begin with inner parenthesis

=\left(x^{3+1}\right)^2

=\left(x^{4}\right)^2

=x^{4*2}

=x^8

Now compare that with =x^k, we get:

k=8

Which is different value that Linda got.

Hence answer of the Linda is wrong.
