Answer:

Step-by-step explanation: the slope would be 1 and the y intercept would be 4.

Answer:

g(- 4) = 12

Step-by-step explanation:

To evaluate g(- 4), substitute x = - 4 into g(x), that is

g(- 4) = (- 4)² - 4 = 16 - 4 = 12

Step-by-step explanation:

Answer:

The length is 42 inches and the width is 14 inches

Step-by-step explanation:

You know the width is 1/3 of the length, and the length is basically the longer side of a rectangle. The width is y-4, so multiply using distributive property to get 3y-12.

You now know that the 2y+6 is equal to 3y-12, so you add 12 to both sides using additive property of addition to get 2y+18=3y.

Then you subtract 2y from both sides to get the unit value of y.

Y is equal to 18.

Then you can plug 18 into the y's to get

2(18)+6 which is 36+6 = 42

18-4   = 14

There you go.

The length is the longer side which is 42 inches and the width is 14 inches

What the question about solve or what?

Answer:

6

Step-by-step explanation:

5 to each players means you have 6 players and then you have 10 left for yourself

Answer:

You can hand out 5 softballs to 6 players.

Step-by-step explanation:

In order to solve this problem, you need to divide 30 balls to each player (In order to have 10 left.) 30 divided by 5 is 6, so you can only hand out 5 balls to 6 players in order to have 10 left out of 40.

Answer: x = 3

Step-by-step explanation:

Answer:

Sebastian did.

Step-by-step explanation:

seb = 94% or 47/50

while frankie = 43/50 or 86%

Also look at 50 if you want and you can see it divides evenly with 100. Basically each mistake you make is 2 percent lost.

Answer: Sebastian

Step-by-step explanation: Divide 43 by 50.

43/50=0.86

tests are graded by the decimal point so he got 86%

since 94% is more than 86% sebastian scored higher

Open circle: < or >

Arrows point outward

Points located at 5 and 18

Answer:

a

Step-by-step explanation:

Answer:

First, we need to solve the equation in the problem for y to put it in slope-intercept form so we can determine its slope:

2y−6x=4

2y−6x+6x=6x+4

2y−0=6x+4

2y=6x+4

2y2=6x+42

2y2=(6x2)+(42)

y=3x+2

The slope-intercept form of a linear equation is: y=mx+b

Where m is the slope and b is the y-intercept value.

Therefore the slope of this equation is m=3

A perpendicular line will have a slope (let's call this slope mp) that is the negative inverse of this line. Or, mp=−1m

Substituting gives:

mp=−13

-2

Step-by-step explanation:

Answer:

{x = 3, x = 4/5 + i(3/5), x = 4/5 - i(3/5)}

So B

Answer with step-by-step explanation:

If x = -1, we can re-write the equation as -5 - 8y = 29.

Step 1: Simplify both sides of the equation.

-5 - 8y = 29

-5 + (-8y) = 29

-8y - 5 = 29

Step 2: Add 5 to both sides.

-8y - 5 + 5 = 29 + 5

-8y = 34

Step 3: Divide both sides by -8.

-8y/-8 = 34/-8

y = -17/4

Answer:

3,-3 on x axis

Step-by-step explanation:

Answer: x² - 5x - 14

Step-by-step explanation: Start with the formula for the area of a rectangle.

Area = length x width

To multiply these two binomials, let's use the F.O.I.L. method.

The product of the first terms is x².

The product of the outer terms is -7x.

The product of the inner terms is 2x.

The product of the last terms is -14.

So we have x² - 7x + 2x - 14 which simplifies to x² - 5x - 14.

m<12 = 66

Step-by-step explanation:

Answer:

x = 4

m∠12 = 66

m∠13 and m∠12 are linear pairs (supplementry angles)

Step-by-step explanation:

m∠9 ≈ m∠15 (Vertical angle)

m∠15 ≈ m∠13 (Corresponding angle)

m∠9 ≈ m∠13

29x - 2 = 27x + 6

2x - 2 = 6

2x = 8

x = 4

m∠13 = 29(4) - 2

m∠13 = 114

m∠13 + m∠12 = 180

180 - m∠13 = m∠12

180 - 114 = 66

m∠12 = 66

Answer:

See below

Step-by-step explanation:

Quadratic function is in general form of:

The function has a minimum if a > 0 and maximum if a < 0

The minimum or maximum point is a vertex of the graph

When b = 0, the min or max point equals to value of c.

f(-2) = 2*(-2)^2 + 8(-2) + 7 = 8 - 16 + 7 = - 1

g(3) = -3*3^2 + 18*3 - 5 = -27 + 54 - 5 = 22

f(-2) = 3/2*(-2)^2 + 6(-2) + 4 = - 6 - 12 + 4 = - 14

!:'=/,)_"86"&8_)&485)&($8

Given parameters:

Number of pages Haley can read = [tex]\frac{5}{8}[/tex] pages

Time to read the pages = [tex]\frac{2}{3}[/tex] min

Unknown:

Number of pages that can be read in 1 min = ?

Solution:

To solve this problem let us find Haley's rate;

       Rate  = [tex]\frac{Number of pages Haley can read}{Time }[/tex]

 Input the parameters and find the rate;

     Rate  = [tex]\frac{5}{8} / \frac{2}{3}[/tex]

     Rate  = [tex]\frac{5}{8} x \frac{3}{2}[/tex]

      Rate = [tex]\frac{15}{16}[/tex] pages/min

Now that we know the rate;  

   In 1 min; number of pages Haley can read;

               Number of pages  = Rate x time

                Number of pages  = [tex]\frac{15}{16}[/tex]  x   1  = [tex]\frac{15}{16}[/tex][tex]\frac{15}{16}[/tex] pages

Haley can read pages [tex]\frac{15}{16}[/tex]  in 1 minute.
