Answer:

2 notebooks are $2.48, 7 notebooks are $8.68

Step-by-step explanation:

Unit rate is 1.24

1.24x2= $2.48

1.24x7= $8.68

Answer:

-1

Step-by-step explanation:

1-x>2

-x>2-1

-x>1

-x/-1>1/-1

x<-1

Answer:

[tex]x < - 1[/tex]

Step-by-step explanation:

first step

try to leave x's in your left and number in your right

-x > 2-1

-x>1

step 2

by moving the sign minus to right it will become plus

and the inequality sign will change also

so x<-1

the region will ( - infinity to -1 )

[tex]( - \infty - 1)[/tex]

Step-by-step explanation:

2x11=22

3(3+x)

22=9x+3x

Subtract nine

13=3x

Multiply 13 by 3=13/3

Convert to decimal

Answer is:4.3

Answer:

y-intercept (0,-5) and AOS x = -4

Step-by-step explanation:

To find the y-int make x = 0 so f(0) = -5

The axis of symmetry (AOS) can be found by the equation x = -b/2a

So AOS = -8a / 2a, so AOS = -4 since b=8a and a = a

Presumably, x is standing in for the question mark.

The pair of vertical angles (DFE and CFV) shown here both have measure 125°. This angle measure is equal to the average of the measures of the arcs intercepted by the chords CE and DV.

So we have

angle DFE = 1/2 (arc CV + arc DE)

125° = 1/2 (x + 200°)

250° = x + 200°

x = 50°

Answer:

m<STR=149 degree

Step-by-step explanation:

To find m<STR

m PQ=186 degree

mSR=112 degree

m<STR=1/2(m PQ+MSR)

m<STR=1/2(186 +112)

⇒1/2(298)

answer⇒149

Answer:

-7/4

Step-by-step explanation:

Hi,

To find the slope of the line, get two points, and divide the change in y over the change in x. So, let's find two points.

(1,-3) and (-3,4)

Change in y: 4 - (-3) = 7 (Remember when you subtract a negative, you add)

Change in x: -3 - 1 = -4

7/-4 = -7/4

-7/4 is your slope.

I hope this helps :)

Answer:

  15.4 square feet

Step-by-step explanation:

The area of the painting will be the area of the sketch multiplied by the square of the ratio of linear dimensions.

  painting area = (0.24 square feet)(8^2) = 15.36 square feet

The area of the painting is about 15.4 square feet.

Answer:

18 days.

Step-by-step explanation:

Takes 6 days to eat 1 apple so multiply 6 by three to get your answer.

Answer:

18 days

Step-by-step explanation:

since the ratio is 3 days to 1/2 that would mean 6 days is to 1 apple, so if you just multiply 6 days by 3 you would get 18 days because you would need to find how many days for 3 apples.

Answer:

6 students are wearing shirts that aren't blue or white

Step-by-step explanation:

1/6 + 2/3 = 5/6  

5/6 are wearing either blue or white so 1/6 isn't wearing blue or white

there are 36 student and 1/6 means 36 divided by 6

36 divided by 6 = 6

Answer:

  the correct answer is marked

Step-by-step explanation:

The denominator of a fractional exponent becomes the index of the radical when the power is written using a radical. The fractional power only applies to the y-factor, so that is all that is under the radical.

  [tex]\displaystyle xy^{\frac{2}{9}}=x\cdot (y^2)^{\frac{1}{9}}=\boxed{x\sqrt[9]{y^2}}[/tex]

Answer:

Review the graph to get answers:

1. The longer the sailboat is, the FASTER it can go. As it is a increasing function.

2. For a boat to reach the speed of 10 kilometers per hour, it needs to be at least 16 feet long.

3. The maximum speed that an 8-foot boat can reach is 7.1 kilometers per hour.

4. Top speed of a 16-foot boat is 10 kilometers per hour and of a 4-foot boat is 5 kilometers per hour.

The ratio is:

A 16-foot sailboat at top speed is 2 times as fast as a 4-foot sailboat at top speed.

Step-by-step explanation:

Step 1: Define

f(x) = -2x² + 3x - 6

f(3) is x = 3 for the function f(x)

Step 2: Evaluate

Substitute in x [Function]:                                                                                f(3) = -2(3)² + 3(3) - 6

Exponents:                                                                                                        f(3) = -2(9) + 3(3) - 6

Multiply:                                                                                                             f(3) = -18 + 9 - 6

Add:                                                                                                                   f(3) = -9 - 6

Subtract:                                                                                                            f(3) = -15

Answer:

Least is 7

Most is 12

Step-by-step explanation:

So 2 shirts for 12.

So 24

Take 24 off of both

Left with 21 to 36

21÷3 is 7

36÷3 is 12

Hope this helps

Answer:

least - $7

most - $12

Explanation:

if the price of a shirt is $12, she must have spent at least $24 on the shirts in total.

the least amount melissa could have spent on a skirt is:

($45 - $24) ÷ 3 = $7

and the most she could have spent is:

($60 - $24) ÷ 3 = $12
