Answer:

Step-by-step explanation:

So, the slope is -3x, the coefficient is a negative number so the line must be as x decreases, y increases and as x increases, y decreases. In this case, the first graph and the last graph represent the negative slope. However, the function has an y-intercept

Answer:

This is a linear equation, the graph of a line. This function is in slope intercept form, y=mx+b . In this example the slope is =riserun=3=31 and the y -intercept is −2

Ben can type 25 words in half a minute. At this rate, how many words can he type in 5 minutes?

Kruka [31]

I can’t see the “students work”. But the answer would be 250 words in 5 minutes.
Here’s how you would set up the equation:
25x(5*2)=
So your first step would be to multiply 5 and two because they’re in parenthesis, which would be 10.
So now you have:
25x10
25 times 10 is 250.
Hope that makes sense and helps! :)

if a square + b square + c square minus ab minus bc minus ca equals to zero, prove that A equals to B equal to C

lawyer [7]

A^2 + b^2 + c^2 - ab - bc - ca = 0
a.a + b.b + c.c = a.b + b.c + c.a

equating term by term:-
a = b
b = c
c = a

Therefore a = b = c

Answer:

$4\sqrt[3]{7x}$

Step-by-step explanation:

Look for the same stuff under the radical symbol. Here, that "stuff" is "7x". Only one answer choice has 7x under the radical.

_____

Here, there are no cubic factors under the radical that can be factored out—either in the problem expression or in the answer choices. If there were cubic factors, you'd want to remove them before making the comparison.

For example, ∛(56x) would be a like radical to ∛(7x) because a cubic factor of 2^3 = 8 can be removed to make it be 2∛(7x).
