1 answer:
frez [133]2 years ago

Answer:

C) None of the above

When you simplify -6+4q+(-6q), you'll end up with -2q-6, which isn't present between the two choices.

-6(q+1)-4q = -10q-6, so that can't be the answer

2(q-3) = 2q - 6. But the 2q isn't negative, so therefore, this isn't the answer either

Therefore, the answer is C: None of the above

Write the equation of the line that passes through points (-4, 5) and (0,13) in slope-intercept form.
LiRa [457]

Answer:

The answer is

y = 2x + 13

Step-by-step explanation:

Remember:

Slope-intercept form: \:  \\ y = mx + b \\  \\ m = slope \\ b = y - intercept

M =  \frac{y_2 - y_1}{x_2 - x_1}

First: Find the slope.

M =  \frac{13 - 5}{0 - ( - 4)} =  \frac{8}{4}   = 2

.

Second: Solve for the y-intercept

y = mx + b \\ 5 = 2( - 4) + b \\ 5 =  - 8 + b \\   \frac{+ 8 =  + 8 \:  \:  \:  \:  \:  \:  \:  \: }{13 = b}

.

Third: Plug in.

y = mx + b \\ y = 2x + 13

Which phrase should be inserted on the line to correctly compare the two fractions? Use the models to help. StartFraction 7 Over
ANEK [815]

Answer:

7/8 is greater than 2/4

Step-by-step explanation:

In this question basically, what we are trying to do is to compare fractions and state which is greater or less.

The first fractions in the question is;

7/8 _ 2/4

Now, one of the best ways to go around comparing fractions is looking at the denominators.

In this question, the denominators in the fractions are 8 and 4.

The next thing to do here is to multiply the numerator and the denominator of the first by 4 and the numerator and the denominator of the second by 8. This makes it possible for us to have the same denominator in both fractions and thus compare both fractions directly.

Thus, what we have would be;

7/8 = 7/8 * 1 = 7/8 * 4/4 = 28/32

Now for the fraction;

2/4 = 2/4 * 1 = 2/4 * 8/8 = 16/32

We can see they both have a common denominator and we can directly compare their numerators.

Obviously, 28 is greater than 16 and this makes a case for the fact that 7/8 is greater than 2/4

So what we have in the blank is ; is greater than

Kindly note that the other part of the question that talks about shading circles is same as saying 7/8 and 2/4

Question D- If the area of a square is 121 square centimeters, what is its side length?
Ipatiy [6.2K]
The formula for the area of a square is the side squared, or multiplied together.

Basically, if the side length is x, the area is x*x or x^2.

We can use that to set up an equation.

x^2=121
x=square root of 121=11

Hope this helps!
