Which number line represents the solution set for this inequality?

−9x −12 ≤ 42

Answer:

30°

Step-by-step explanation:

Step 1:

2x + 10 + 4x + 80 = 180     Sum of a line

Step 2:

6x + 90 = 180      Combine Like Terms

Step 3:

6x = 90     Subtract 90 on both sides

Answer:

x = 30°       Divide

Answer:

Step-by-step explanation:

[tex]y=\frac12(x+4)(x-2)\quad\implies\quad x_1=-4\,,\ \ x_2=2[/tex]

vertex is (p, q) where:

[tex]p=\dfrac{x_1+x_2}2=\dfrac{-4+2}2=\dfrac{-2}2=-1\\\\q=f(p)=\frac12(-1+4)(-1-2)=\frac12(3)(-3)=-\frac92=-4.5[/tex]

So the vertex is: (-1, -4.5)

Answer:

720 gallons

Step-by-step explanation:

First, find how many gallons are cleaned per hour.

You can use a ratio:

36 gallons  =   x gallons

1/4 hour            1 hour

Cross multiply:

36 (1) = 1/4x

36 = 1/4x

(36 = 1/4x) (4/1)

144 = x

x = 144

Then, use this info to find how many gallons per 5 hours.

You can use a ratio:

144 gallons  =   y gallons

   1 hour              5 hour

Cross multiply:

144 (5) = 1y

720 = y

y = 720

There are 720 gallons cleaned per 5 hours.

Answer:

150 students

Step-by-step explanation:

30%+60%=90%

15=10%

multiply by 100 on both sides then simplify

Answer: n= 3/2

yes!

Step-by-step explanation:

calculate the sum 4n-6=6n-9

move the varaible to the left hand side and change its sign

4n-6n-6=-9

collect terms -2n=-9+6

dive both sides of the equation by -2

Answer:

5x+2

Step-by-step explanation:

6x-x=5x and 5-3=2

so 5x+2 is the answer.

Answer:

A. 10

Step-by-step explanation:

Answer:

x = 1/5

Step-by-step explanation:

Step 1: Write equation

-5x - (-7 - 4x) = -2(3x - 4)

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

-5(1/5) - (-7 - 4(1/5)) = -2(3(1/5) - 4)

-1 - (-7 - 4/5) = -2(3/5 - 4)

-1 - (-39/5) = -2(-17/5)

-1 + 39/5 = 34/5

34/5 = 34/5

Answer:

multiply 15 by 0.75 and you get $11.25

Answer:

Step-by-step explanation:

you could do;

10 x -2 = 20

-2 x (-2) x 10 divided by (-2) + 10 + 10 + 10 +10 =20

4 + 4 - 10 x -2 - 4 - 4 = 20

Answer:

13 and 6

Step-by-step explanation:

Answer:

Using Pyhagoras theoram,

(H)^2 = (B)^2 + (P)^2

B = 13 in

P = 5 in

[tex](h)^{2} = (13)^{2} + {(5)}^{2} \\ = > (h)^{2} = 169 + 25 \\ = > (h)^{2} = 194 \\ = > h = \sqrt{194} \\ = > h = 13.92[/tex]

Hence, the missing side is 13.92 inhes.

Answer:

13.93

Step-by-step explanation:

[tex]5^{2} + 13^{2} = c^{2}[/tex]

[tex]25 + 169 = 194 = c^{2}[/tex]

[tex]\sqrt{194} = c^{2}[/tex]

[tex]13.92838827718 = c[/tex]

then round up to 13.93

Answer:

(negative infinity, 4]

Step-by-step explanation:

Reminder: the range is all the possible y values the function can get by plugging in x values.

Since this is a downward opening parabola, it won't have a lower boundary, which means that the answer must be (negative infinity, 4]

We can further check that's correct by seeing that the parabola has its vertex at 4, which is written in the answer.

That means the correct answer must be (negative infinity, 4]

Answer:

2 = 67

3 = 113

4 = 67

5 = 113

6 = 67

7 = 113

8 = 67

Step-by-step explanation:

opposite angle have to equal 180 because if you combine them they just become the line.

since the lines are parallel, measurements will be the same for the bottom set of angles as they are the top set of angles.

Answer:

A rewards customer earns 2 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same.

did the test on edge

Answer:

73 degrees

Step-by-step explanation:

The interior angle equals to 180. 73+37+ m<2 = 180. That means angle 2 is 70 degrees.

m<1 and m<C and equal due to alternate interior angles. That means angle 1 is 37 degrees.

We know angles 1 and 2 equal to 37 and 73. That means the angles are equal to the interior triangle. 70+37= 107.      180-107= 73 Degrees
