0.857$ (Its really big in answer but This is the average result.

The REAL answer

0.857142857$

a = 4, R = 147, T = 33

Step-by-step explanation:

find a

a/(a + 7) = (16/3)/(44/3)

a/(a + 7) = 16/44

44a = 16a + 112

44a - 16a = 112

28a = 112

a = 112/28

a = 4

find R

2x + 5 = 3x - 9

5 + 9 = 3x - 2x

14 = x

m ∠R = 180° - (2x + 5)

= 180 - (2(14) + 5)

= 180 - (28 + 5)

= 180 - 33

= 147°

find T

m ∠T = 3x - 9

= 3(14) - 9

= 42 - 9

= 33°

Answer:

1.

Step-by-step explanation:

+ (-4) = - 4 so we have

-2 + 7 - 4

= 5 - 4

= 1.

385 miles

Step-by-step explanation:

440/16 = x/14

16x = 440 × 14

16x = 6,160

x = 6,160/16

x = 385 miles

Answer:

Step-by-step explanation:

1.5 divided by .75

Answer:

2/3 or 0.66666666666

Step-by-step explanation:

Answer:

18/24 or 75%

Step-by-step explanation:

Okay so you already know that he got 16/24 which means that there were 8 questions that were wrong because 24-16= 8

So he has 16 points that we know of and 8 questions that he got wrong.

If he lost 1/4 of a point when he got it incorrect 1/4= 0.25

0.25 x 8 = 2points

So he got to points

16+ 2= 18 so now it is 18/24

If you have to show Out for 100% it would be 75%

Answer:

1) [tex]y-6=-\frac{2}{3} (x-1)[/tex] and 2) [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]

Step-by-step explanation:

Ikr the bots are annoying.

Point-slope form is written as: [tex]y-y_1=m(x-x_1)[/tex]

Slope intercept form is written as: [tex]y=mx+b[/tex]

We also need to find the slope before putting it in this form, which can be done by [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

1) Points given are (1,6) and (-2,8)

Slope: [tex]m=\frac{8-6}{-2-1} =-\frac{2}{3}[/tex]

You can choose either of the two points to put into the formula. I just chose (1,6)

Answer: [tex]y-6=-\frac{2}{3} (x-1)[/tex]

2) Same points as before and we have the same slope as before. All we need is to find the y intercept which is our b in the equation. You can easily do this by plugging in a point and solving for b. I will choose point (1,6) again.

[tex]6=-\frac{2}{3} (1)+b[/tex]

[tex]6=-\frac{2}{3} +b[/tex]

[tex]6+\frac{2}{3}=-\frac{2}{3} +\frac{2}{3} +b[/tex]

[tex]b=6+\frac{2}{3}=\frac{20}{3}[/tex]

Answer: [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]

Answer:

Step-by-step explanation:

let the eq. of parabola be

y=ax²+bx+c

points (-1,0),(2,0),(3,4) and (0,-2) lie on it.

0=a-b+c

0=4a+2b+c

subtract

3a+3b=0

a=-b

4=9a+3b+c

-2=0+0+c

c=-2

a-b-2=0

-b-b-2=0

-2b-2=0

b+1=0

b=-1

a=-b=-(-1)=1

eq. of parabola is

y=x²-x-2

Answer:

x×2+13=5

Step-by-step explanation:

We use x as the unknown number, and we just put what's in the word problem! The answer is in the question.

Equation Set-Up

x×2+13=5

Remember order of operations! (PEMDAS)

Then you solve the equation.

Because of PEMDAS, we know that multiplication is the first thing we have to do.

x×2=2x

So now, our equation looks like this.

2x+13=5

We subtract 13 from the +13 to cancel it out, but that means that we also have to subtract 13 from the 5 on the other side. We are now left with this.

2x=-8

Then, we divide -8 by 2, which gives us...

x=-4

Pablo's number is -4.

I hope I helped! Have a great day.

Answer:

anser is 56

Step-by-step explanation:

Answer:

1.) x = -5

   y = -4

Point to graph: (-5, -4)

2.) x = 0

    y = -6

Point to graph: (0, -6)

3.) x = 5

    y = 8

Point to graph: (5, 8)

Step-by-step explanation:

Substitute x for the given value, then find y.

1.) -2(-5)-5y = 30

10-5y = 30

-5y = 20

y = -4

2.) -2(0)-5y = 30

-5y = 30

y = -6

3.) -2(5)-5y = 30

-10-5y = 30

-5y = 40

y = -8

Answer:

y values are

-4

-6

-8
