Answer:

Step-by-step explanation:

2. (-2-1)/(1-0)= -3/1 = -3

3. (6-5)/(3-2)= 1/1= 1

4. (1-1)/(-6-6)= 0/-12= 0

6. (-2-2)/(5-5)= -4/0 = undefined

5. (8-6)/(4-4)= 2/0 = undefined

7. (-5-5)/(-3-2)= -10/-5= 2

8. (-8-8)/(7-9)= -16/-2= 8

9. (1+8)/(-8+5)= 9/-3= -3

10. (7-10)/(-3+3)= -3/0= undefined

11. (17-18)/(18-17)= -1/1= -1

12. (1+4)/(4+6)= 5/10 = 1/2

13.(4-0)/(-2-10)= 4/-12 = -1/3

14. (-2+1)/(-8-2)= -1/-10= 1/10

15. (-2+9)/(3-5)= 7/-2= -7/2

16. (-5-6)/(3-12)= -11/-9= 11/9

Answer:

x= 5

Step-by-step explanation:

Using the Side Splitter Theorem, we will make a proportion using the values given:

Afterwards, you can check to see that 20/10 is equal to 44/22.

Answer:

x < 3

Step-by-step explanation:

The line is moving to negative so the number is less than 3

the white circle (or opened circle) indicates that we do NOT include that number so it is x < 3

Answer:

Your solution is (9, 27) or x = 9, y = 27

Step-by-step explanation:

y = 2x + 9

y = 4x - 9

We can see that both of these equations equal y, so we can set them equal to each other.

2x + 9 = 4x - 9

Add 9 to both sides.

2x + 18 = 4x

Subtract 2x from both sides.

18 = 2x

Divide both sides by 2.

9 = x

Now we want to find y. To do this, plug x = 9 back into one of the original equations.

y = 2(9) + 9

Multiply.

y = 18 + 9

Add.

y = 27

Your solution is (9, 27)

Check your answer by plugging x = 9 and y = 27 back into the original equations.

y = 2x + 9

27 = 2(9) + 9

27 = 18 + 9

27 = 27

y = 4x - 9

27 = 4(9) - 9

27 = 36 - 9

27 = 27

Your answer is correct.

Hope this helps!

Answer:

x=9,y=27

Step-by-step explanation:

y=2x+9,........equation 1

y=4x-9..........equation 2

from equation 1 and 2

we get

2x+9=4x-9

9+9=4x-2x

x=18/2=9

substituting value of x in equation 1

y=2×9+9=18+9=27

Answer:

Step-by-step explanation:

3x +39 =90

3x =90-39

3x=51

make it in fraction

3x over 3 equals to 51 over 3

simplify

= 51

Answer:

x = 17

Step-by-step explanation:

a straight line equals 180º so each side is 90º.

90 - 39 = 51

3 x __ = 51

3 x 17 = 51

so..x = 17

Answer:

Hat costs 4.00

T-Shirt costs 9.00

Step-by-step explanation:

Let the t-shirt be t and the hat be h

7t+h=67

5t+h=49

Equating by eliminating the h and subtracting

the two equations,

2t=18

t=9.

If t =9 in 5t + h= 49 then

5×9+h=49

45+h=49

h=4

Answer:

8x³ - 2x² - 51x - 45

Step-by-step explanation:

Given

(x - 3)(2x + 3)(4x + 5) ← expand second/third factors using FOIL

= (x - 3)(8x² + 22x + 15) ← distribute

= x(8x² + 22x + 15) - 3(8x² + 22x + 15) ← distribute parenthesis

= 8x³ + 22x² + 15x - 24x² - 66x - 45 ← collect like terms

= 8x³ - 2x² - 51x - 45

Answer:

8x^3-2x^2-51x-45

Step-by-step explanation:

(x − 3)(2x + 3)(4x + 5)

(2x^2+3x-6x-9)*(4x+5)

(2x^2-3x-9)*(4x+5)

= 8x^3-2x^2-51x-45

Answer:

x^2 -4x -21

Step-by-step explanation:

Here, we want to write a quadratic polynomial

We have the sum as -4

Let us have x as the variable

so the sum of the variables is -4x

while the product is -21 x^2

Two factors of 21 that can work here is -7x and 3x

So we have

x^2 - 7x + 3x -21

= x^2 -4x -21

Answer:

a = ± 5

Step-by-step explanation:

Given

a² + 12² = 13² , that is

a² + 144 = 169 ( subtract 144 from both sides )

a² = 25 ( take the square root of both sides )

a = ± [tex]\sqrt{25}[/tex] = ± 5

Answer:

Yes

Step-by-step explanation:

Being proportional means that if you divide the Y value by the X number for each ordered pair, they all equal the same number

For this case, this is proportional because you need to multiply by 6 to get the Y value.
