Answer:

Below -2: -2.5, -4.5

Between -2 and 1: -0.5, 0.5

Above 1: 1.5, 4

Step-by-step explanation:

Below -2 answer: We know that -2 is below 0, so we should look for negative numbers that have a lesser value than -2. Thus, we are left with -2.5 and -4.5

Between -2 and 1 answer: In this case, we must find one or more of the values given to us that fit this requirement. In other words, find values that are greater than -2 but less than 1. So, we are left with -0.5 and 0.5.

Above 1 answer: For the final box, we are left with the values of 1.5 and 4. We know that the requirement is that the values must be greater than 1, so we can fact-check this with the values given:

1.5 > 1

4 > 1

So, the answers for the final box will be 1.5 and 4.

Hope this helps!

1.5 would be above 1, -4.5 would be below -2, 4 would obviously be above 1, 0.5 would be between -2 and above 1, and lastly -0.5 would be below -2. Hope this helped!

Answer:

Step 1, all the exponents are increased by 4

Step-by-step explanation:

The first incorrect step occurred in Step 1, where all the exponents were increased by 4.

This is mathematically incorrect due to exponential rules. When distributing exponents inside parentheses, we have to multiply the existing exponents inside the parentheses by the exponent outside the parentheses.

For example, (x²)³ is not x²⁺³, but rather, x⁽²⁾⁽³⁾.

We multiply the exponents instead of adding them together.

Therefore, the correct Step 1 should multiply all the variables' exponents by 4.

Steps 2 and 3 are correct since we do add the exponents when multiplying exponents with the same base, and we do subtract exponents with the same base when dividing.

Answer:

y=20

Step-by-step explanation:

0.6(y-10)=6

0.6y-6=6

0.6y=6+6

0.6y=12

y=12/0.6

y=20

the mistake is added 10 to both sides

A line passes through the points (–3, –4) and (6, 2). What number is the x-intercept?
LuckyWell [14K]

Answer:

<h2>D. 3</h2>

Step-by-step explanation:

\bold{METHOD\ 1}

\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{x-intercept:}\ (x,\ 0).\\\\\text{Susbtitute the coordinates of the points to the formula of a slope}\\\\(-3,\ -4),\ (6,\ 2),\ (x,\ 0):\\\\m=\dfrac{2-(-4)}{6-(-3)}=\dfrac{2+4}{6+3}=\dfrac{6}{9}=\dfrac{6:3}{9:3}=\dfrac{2}{3}\\\\m=\dfrac{0-2}{x-6}=\dfrac{-2}{x-6}\\\\\text{Therefore we have the equation:}\\\\\dfrac{-2}{x-6}=\dfrac{2}{3}\qquad\text{cross multiply}\\\\2(x-6)=(-2)(3)\\\\2(x-6)=-6\qquad\text{divide both sides by 2}\\\\x-6=-3\qquad\text{add 6 to both sides}\\\\x=3

\bold{METHOD\ 2}\\\\\text{Look at the picture.}

Mark points in the coordinate system.

Lead a line through these points.

Read x-intercept.
