Which graph represents the compound inequality?

Answer:

10 9/14

Step-by-step explanation:

7+3=10

1/2=7/14

1/7=2/14

Answer:

1st answer is 6, 2nd is 5, 3rd is 5

Step-by-step explanation:

3x-2=x+10

3x-x=10+2

2x=12

x=12÷2

x=6

x+4=19-2x

x+2x=19-4

3x=15

x=15÷3

x=5

8z-20=z+15

8z-z=15+20

7z=35

z=35÷7

z=5

plzz mark me as brainliest

Answer:

3x-2=x+10

x=6

x+4=19-2x

x=5

8z-20=z+15

z=5

Step-by-step explanation:

3x-2=x+10

+2 on both sides

3x-2(+2)=x+10(+2)  =>  3x=x+12

subtract x on both sides

3x(-x)=x(-x)+12   =>  2x=12

divide 2 on both sides

2x/2=12/2

= x=6

x+4=19-2x

subtract 4 on both sides

x+4(-4)=19(-4)-2x    =>    x=15-2x

add 2x on both sides    

x(+2x)=15-2x(+2x)     =>    3x=15

divide 3 on both sides

3x/3=15/3

= x=5

8z-20=z+15

subtract z on both sides

8z(-z)-20=z(-z)+15    =>  7z-20=15

add 20 on both sides

7z-20(+20)=15(+20)

7z=35

divide 7 on both sides

7z/7=35/7

= z=5

Answer:

[tex]3x - 70 = 50 + x \\ 2x = 120 \\ x = 60[/tex]

so ..

X=60

and

3x-70=180-60=110

Step-by-step explanation:

Answer:

angle LKM = 110 degrees

Step-by-step explanation:

angle JKL = 180 - (3x-70) because they are supplementary angles

angle JKL + x + 50 = 180 degrees because the sum of all the interior angles of a triangle equals 180 degrees

substituting for angle JKL:

180 - (3x - 70) + x + 50 = 180

180 - 3x +70 + x + 50 = 180

simplify:

-2x = -120

x = 60 degrees

angle LKM = 3(60)-70 = 110 degrees

Answer:

[tex]y=\frac{5}{4}x+\frac{11}{2}[/tex]

Step-by-step explanation:

y = (5/4)x + (5/4)

Slope = 5/4

Parllel lines have same slope

Slope of the line parallel  to this line = 5/4

(-2 , 3)

y -y1 = m(x -x1)

y - 3 = (5/4)(x - [-2])

[tex]y -3 =\frac{5}{4}(x +2)\\\\y - 3 =\frac{5}{4}x + 2*\frac{5}{4}\\\\y -3 =\frac{5}{4}x + \frac{5}{2}\\\\y =\frac{5}{4}x + \frac{5}{2}+3\\y =\frac{5}{4}x+\frac{5}{2}+\frac{3*2}{1*2}\\\\y=\frac{5}{4}x+\frac{5}{2}+\frac{6}{2}\\\\y=\frac{5}{4}x+\frac{11}{2}[/tex]

Answer:

x = - 11/4

Step-by-step explanation:

20- 3x = 9 - 7x

Add 7x to both sides

20 - 3x + 7x  =  9 - 7x + 7x

20 + 4x = 9    

Now,Subtract 20 from both sides

20 -20 + 4x = 9 - 20

             4x = -11        {Divide both sides b 4}

               x = -11/4

Answer:

= -11/4

Step-by-step explanation:

Rearrange terms

−3+20=9−7

− 3 + 20 = − 7 + 9

Subtract  20  from both sides of the equation

− 3 + 20 = − 7 + 9

− 3 + 20 − 20 = − 7 + 9 − 20

Simplify / Subtract the numbers

− 3 = − 7 − 1 1

Add  7 7x 7x  to both sides of the equation

− 3 = − 7 − 1 1

− 3 + 7 = − 7 − 1 1 + 7

Simplify / Combine like terms

4 = − 1 1

Divide both sides of the equation by the same term

4 = −11

4/4 = -11/4

Simplify / Cancel terms that are in both the numerator and denominator

= -11/4

Answer:

-26 is your answer

Step-by-step explanation: 2³ first which = 8 then solve in the parenthesis and all inside parenthesis = -19 so now you have -19+9-4². Now, solve 4² which = 16 so now you have -19+9-16 then solve that and it should give you -26.

Answer:

D

Step-by-step explanation:

Answer: X=-1, Y=1

Step-by-step explanation:

The answer to this problem is:

X= -1  Y=1

Answer (assuming it can be in slope-intercept form):

y = x - 5

Step-by-step explanation:

1) First, find the slope of the equation. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], and substitute the x and y values of the given points into it. Then, solve:

[tex]m = \frac{(2)-(1)}{(7)-(6)} \\m = \frac{2-1}{7-6} \\m = \frac{1}{1} \\m = 1[/tex]

2) Now that we know the slope and at least one point the line crosses through, we can write an equation of the line in point-slope form, or [tex]y-y_1 = m (x-x_1)[/tex]. Substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.

Since [tex]m[/tex] represents the slope, substitute 1 for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, use any one of the given points (either one is fine, either way the equation will represent the same line) and substitute its x and y values into the equation. (I chose the point (6, 1), as seen below.) Finally, isolate y to put the equation in slope-intercept form.

[tex]y-1 = 1(x-6)\\y -1 = x-6\\y = x -5[/tex]

Answer:

at 12 hours, it's 9 inches.

at 14 hours, it's 14 inches.

at 13 hours it's 16 inches.

I'm not sure if you needed how many inches it snowed an hour, or if you just needed the hours and inches. My apologies.

Answer:

54 degrees

Step-by-step explanation:

Every side of a regular pentagon is same.

So we have an  isosceles triangle. The  correspond angle of y, must equal to y (degree) too.

Also, every inner angle of a regular pentagon is 360/5=72. So we can calculate angle y, by the equation y+y+72=180.

y=54

We have a parallelogram and a half of circle.

Answer:

The rule shows that each term is 8 more than the previous term, so the common difference is 8.The explicit formula of an arithmetic sequence is the initial term plus (n – 1)d.The explicit rule for this function can be found by substituting 42 for a1 and 8 for d.The explicit rule for the sequence is  42 + (n – 1)8.

Answer:

Step-by-step explanation:

x = -y + 10

Substitute into the second equation

-y + 10 = y + 4

-2y = -6

y = 3

Plug into first or second equation.

x = -3 + 10 = 7

x = 3 + 4 = 7

So the ordered pair is (7,3)

Answer:

30

Step-by-step explanation:

Looking at the question we will notice that every 6 that Troy puts together Drake makes 10 so its simple, Troy makes 18 so we divide that by 6 meaning we get 3. We then get 3 and multiply it by 10, Thus 30 shall be our answer.

Answer:

55 degrees

Step-by-step explanation:

Complementary angles are two angles that equal 90 degrees together so if one angle is 35 degrees then the other must be able to add towards that to make 90 degrees

90=35+∠2

-35     -35

55=∠2

Answer:

y/2 = 4.5

Step-by-step explanation:

1/4x + 2y = 11/4

distribute by 4 to eliminate fractions

  x + 8y = 11

+ -x - 6y = 7

        2y = 18

          y = 9

half of 9 = 4 1/2
