Savannah is 9 years older thanDevante. The sum of their ages is 53. How old are Savannah and Devante?
(A) First write an equation you can use to answer this question. Use x as your variable.
The equation is _______
Answer: Devante is _______
and Savannah is ______

Answers

Answer:

Devante is 23 and Savannah is 32.

Step-by-step explanation:

We can set up a system of equations.

s - savannah's age

d - devante's age

s = d + 9

s + d = 53

Now we can substitute (d + 9) for s in the second equation.

(d + 9) + d = 53

2d + 9 = 53

2d = 46

d = 23

To find Savannah's age, we just add 9 to Devante's age. (plugging in 23 for d)

23 + 9 = 32

s = 32

11) Elsa took out a $2,200 loan with a 2-year term to buy a car at a 6% simple interest rate. How much will she have to pay IN INTEREST? *

Answers

Answer:

$264

Step-by-step explanation:

A 6% interest means that you have to pay 6% of the loan every period (which in this case is a year because it isn't stated anywhere). 6% of $2.200 is equal to $132, so for a loan of 2 years Elsa has to pay [tex]\$132 \cdot 2 = \$264[/tex], which is exactly what the question was asking for.

Which equation best represents the graph shown above?

Answers

Answer:

Step-by-step explanation:

Choose an x point. Then plug it in and see if you get the correct y.

For example, I chose an x point of -1. When x = -1, you can see that y = 4.

Plug it in to the equations, and you find that B is correct.

y (4) = [tex]x^{2}[/tex] (-1 x -1) - 2x ( 2 times -1) + 1

4 = 1 - (-2) + 1

4 = 1 + 2 + 1

4 = 4

Answer what you can please and show work. I will mark you brainliest.

Answers

Answer:

part 1:

1) AB = BC = 10

2) DE = sqrt(10² - 9²) = sqrt(19)

3) CED = 90⁰

4) BCD = (90⁰ - 53⁰).2 = 74⁰

part 2:

because FGHJ is a rhombus

=> GK = KJ

<=> 3x + 1 = x + 9

<=> 2x = 8

<=> x = 4

and we have:

GHK + FGK = 90⁰

<=> (4y - 8)/2 + y + 4 = 90⁰

<=> 2y - 4 + y + 4 = 90⁰

<=> 3y = 90⁰

<=> y = 30

5) with x = 4 => GJ = 2KJ = 2.(4 + 9) = 26

6) JK = 4 + 9 = 13

7) with y = 30, HFJ = 90 - FGK = 90 - 34 = 56⁰

8) HJF = 2.FGK = 2.34 = 68⁰

part 3:

because MNLO is rectangle

=> MP = PO

<=> 5a - 7 = 2a + 8

<=> 3a = 15

<=> a = 5

9) with a = 5, MO = 2.PO = 2.(2.5 + 8) = 2.18 = 36

10) NP = PO = 2.5 + 8 = 18

11) LM² = LN² - MN² = MO² - 26² = 36² - 26² = 620

=> LM = 2sqrt(156) = 24,9

12) tan NMO = NO/MN = LM/MN = 24.9/26

=> NMO = 43,8⁰

part 4:

because RSTU is square

=> SR = RU

=> 2k + 7 = 3k - 2

<=> k = 9

with k = 9 =>RU = SR = 2.9 + 7 = 25

13) RV = 1/2.SU = 1/2.sqrt(25² + 25²) = 17,7

14) SU = 2RV = 2.17,7 = 35,4

15) perimeter RSTU = 25.4 = 100

16) area RSTU = 25² = 625

35 feets

Step-by-step explanation:

Initial Position = - 25 feets

Final height reached after jumping = 10 feets

The vertical distance traveled by dolphin :

Final height reached - Initial position

(10 feets) - (-25 feets)

10 feets + 25 feets

= 35 feets

This line segment will be dilated with the point of dilation at (4, 1) and a scale factor of 2. What is the x-coordinate of one of the endpoints of the dilated segment

Answers

The x-coordinate of one of the endpoints of the dilated segment should be 8.

Calculation of x-coordinate:In the case when a coordinate point (x, y) should be dilated by a factor k, so the coordinate should be (kx, ky).Since the coordinate (4,1), so if this coordinate is dilated by a factor of 2 so the new coordinate points should be at (2(4), 2(1))

Now
