Can anyone help me with this

Answer:

Step-by-step explanation:

Your answer

Assume Joey is x, Martina is y

According to 1st condition.

Eq 1. Y = x + 14

According to 2nd condition

Eq2. (Y+3)= 3(x+3)

Put value of y in eq 2,,,,,,,, x = 4

Put value of x in eq 1. ,,,,,,,,, y = 18

Answer:

x = - 6, x² = [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

[tex]2x^{2}[/tex] + 12x - 7x - 42 = 0

2x^{2} (x + 6) - 7 (x + 6) = 0

(x + 6) x (2x - 7) = 0

x + 6 = 0

2x - 7 = 0

x = - 6

x = [tex]\frac{7}{2}[/tex]

x = - 6, x² = [tex]\frac{7}{2}[/tex]

Answer:

x^2 - 16

Step-by-step explanation:

Answer:

x² - 16

Step-by-step explanation:

(x - 4)(x + 4)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x + 4) - 4(x + 4) ← distribute both parenthesis

= x² + 4x - 4x - 16 ← collect like terms

= x² - 16

Answer:

A is the correct answer

Step-by-step explanation:

If you plug y=x+10 in for the Y variable you just have to solve by multiplying.

1.) It should look like this:

2x + 3(x +10) = 40

2.) You will distribute the three which will make the equation look like this:

2x + 3x + 30 = 40

3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.

Hope that helps

Answer:

0

Step-by-step explanation:

The slope should be a 0 slope, since both of the Y values are the same.

Answer:

the answer is 27

Step-by-step explanation:

hope this helps

Answer:

x = 27

Step-by-step explanation:

3x + 9 = 180 - 90

3x + 9 = 90

3x = 81

x = 27

Answer:

42

Step-by-step explanation:

76-34=42

Answer:

42 degrees

Step-by-step explanation:

If you take 76 and subtract it from 34 you get 42 as your other angle.

Answer:

Minimum Values:

x = 0, y = 1, z = 3

Maximum Values:

x = 7 , y = 11 , z = 47

Step-by-step explanation:

FOR MINIMUM VALUES:

0<= x <= 7

It is clear from the above inequality that the minimum value of x must be 0.

y>= 1

This inequality shows that the minimum value of y must be 1. Using these minimum values of x and y to get the minimum value of z:

z = 2x + 3y

z = (2)(0) + (3)(1)

z = 3 (Minimum)

FOR MAXIMUM VALUES:

0<= x <= 7

It is clear from the above inequality that the maximum value of x must be 7.

x + y <= 11

To calculate maximum value of y we can use the minimum value of x in this inequality:

0 + y <= 11

y <= 11

Hence, the maximum value of y is 11.

Using these maximum values of x and y to get the maximum value of z:

z = 2x + 3y

z = (2)(7) + (3)(11)

z = 47 (Maximum)

Step-by-step explanation:

Let's solve your equation step-by-step.

4−(9g−5)=−18

Step 1: Simplify both sides of the equation.

4−(9g−5)=−18

4+−1(9g−5)=−18(Distribute the Negative Sign)

4+−1(9g)+(−1)(−5)=−18

4+−9g+5=−18

(−9g)+(4+5)=−18(Combine Like Terms)

−9g+9=−18

−9g+9=−18

Step 2: Subtract 9 from both sides.

−9g+9−9=−18−9

−9g=−27

Step 3: Divide both sides by -9.

−9g−9=−27−9

g=3

Answer:

B its the correct answer

Answer:

D. 10x-20

Step-by-step explanation:

The perimeter is just all four sides added together

(3x-2)+(3x-2)+(2x-8)+(2x-8)

add together like terms

3x+3x+2x+2x=10x

-2+-2+-8+-8=-20

write in order

10x-20

Answer:

n=15

Step-by-step explanation:

(subtract 6 from both sides of the equation.)

6+n/5=9

6+n/5-6=9-6

(Now you will have to simplify.)

n/5=3

(You will have to multiply all terms by the same value to eliminate fraction denominators.)

n/5=3

5xn/5=5x3

(You will now have to simplify.)

n=15

And that's how you get your answer.

Answer:

(2,-4)

Step-by-step explanation:

2y=-x-6                                        2+2y=-6

y=-1/2x-3                                      2y=-8

6x+2(-1/2x-3)=4

6x-x-6=4
