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:

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:

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:

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:

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:

D is false

Step-by-step explanation:

Answer:

it's 6

Step-by-step explanation:

2*3 is 6 and I*I is i^2 which equals to 1 so overall 6

Answer:

-6

Step-by-step explanation:

2i* 3i

Multiply the numbers 2*3 = 6

Multiply the imaginary number i*i = i^2

We know that i^2 = -1

6* i^2 = 6*-1 = -6

Answer:

6

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

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)

Answer:

5

Step-by-step explanation:

If 30 equals 4 and 60 equals 7, then 40 will equal 5 and 50 will equal 6.

and so on

Answer:

x = 2

Step-by-step explanation:

3 x 2 is 6. 6 + 5 is 11. This is the only correct one.

Hope it helps!

Answer:

0

Step-by-step explanation:

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

Answer:

GCF (4, 16) = 4

GCF (2x, 4) = 2

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:

(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

5x=10

x=2

y=-4

Step-by-step explanation:

The ASA  (Angle-Side-Angle) states that: If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.

SSS, SAS, ASA, AAS

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
