Answer:

Option B:

Equation of the line of best fit in slope-intercept form is .

**Solution:**

Take two points on the line (0, 1) and (4, 3).

So, .

Slope of the line:

y-intercept means the point which crosses at y-axis.

Here the point on the y-axis is (0, 1).

**y-intercept (b) = 1**

Slope-intercept form:

y = mx + b

**Equation of the line of best fit in slope-intercept form is ****.**

**Option B is the correct answer.**

8 plus 7 equals 6 + blank

One hour after a hiker left a camp, a cyclist set out to catch up. If the hiker traveled 3 miles per hour and the cyclist travelled 6 miles per hour faster, how long will it take the cyclist to catch up with the hiker?

Sketch the quadratic function f(x) = x2 + 4x + 3. Which key feature of the graph is given incorrectly?A) minimum (-2, -1) B) y-intercept (0, 2) EliminateC) x-intercept (-3, 0) D) x-intercept (-1, 0)

Given x+2<-5 choose the solution set.

True

B.

False

**Answer:**

A

**Step-by-step explanation:**

True and for you middle schoolers if you cut of someone that had the right-or way during your drivers test the test will end and you will fail

I = P x r x t

P is the principal amount, $420.00.

r is the interest rate, 3.5% per year

t is the time involved, 5 years

420 × 0.035 × 5 = 73.50

73.50 + 420 = 493.5

P is the principal amount, $420.00.

r is the interest rate, 3.5% per year

t is the time involved, 5 years

420 × 0.035 × 5 = 73.50

73.50 + 420 = 493.5

**Answer:**

Divide the numerator by the denominator. Your answer would be the whole number, and the remainder would be your fraction.

4 weeks in a month.

1st month; 10 x 4 = $40

2nd month; 40 x 2 = $ 80

3rd month; 80 x 2 = $160

4th month; 160 x 2 = $320

40 + 80 + 160 + 320 = $ 600

1st month; 10 x 4 = $40

2nd month; 40 x 2 = $ 80

3rd month; 80 x 2 = $160

4th month; 160 x 2 = $320

40 + 80 + 160 + 320 = $ 600

ok ratio and proportion

realheight:shadow=15:20

slide shadow=16

therefor find realheightslide

15:20=realheightslide:16

simplify

3:4=realheight:16

fractionfy

3/4=realheight/16

multiply both sides by 16

48/4=realheight

12=realheight

aswer is 12 feet

realheight:shadow=15:20

slide shadow=16

therefor find realheightslide

15:20=realheightslide:16

simplify

3:4=realheight:16

fractionfy

3/4=realheight/16

multiply both sides by 16

48/4=realheight

12=realheight

aswer is 12 feet

Which constant would you add to the RIGHT side of the

quadratic equation in order to solve by completing the

square? Remember, this is a two-step process

ANSWER

The correct answer is D

EXPLANATION

The given quadratic expression is

Divide through by 3

We now add the square of half the coefficient of x because the coefficient of the quadratic term is now unity.

The constant we would add is

The correct answer is D

**Answer: Option D.**

**Step-by-step explanation: **

Given the quadratic equation , you can observe that the leading coefficient is not 1, then you have to divide both sides of the equation by 3:

Now, you can observe that the coefficient of the x-term is , so you must divide it by 2 and square it. Then you get:

Therefore, you must add to both sides of the equation.
