Answer:

(-4, 7)

Step-by-step explanation:

x is found on the x axis its -4

to find y you go up to where the point bvb is it is located at positive 7

Answer:

(-4,7)

Step-by-step explanation:

This is the answer because the x-axis is -4, and the y-axis is 7. If it was put in any other way it would be wrong.

Answer:

5 years

Step-by-step explanation:

1. if able's age is x, then his sister's is x-4, and his brother's is 2x

2. if these sum to 32, then we can formulate the equation x+(x-4)+2x=32

3. now solve for x, 4x-4=32, 4x=36, x=9

4. if able's sister is x-4 years old, she is 9-4, or 5 years old

Answer:

it is a whole number but because rational numbers include all intergers and whole numbers it is also a rational number

Step-by-step explanation:

Answer:

x = 3.9

Step-by-step explanation:

5(2x-3)=24

Distribute

10x -15 = 24

Add 15 to each side

10x-15+15 = 24+15

10x = 39

Divide each side by 10

10x/10 = 39/10

x = 3.9

Answer:

w = 50

Step-by-step explanation:

600 = 12w

600/12 = 12/12w

w = 50

Answer:

Option 2

Step-by-step explanation:

If you multiply 2 by 2 you get 4. If you multiply 3 by 2 you get 6. If you multiply 4 by 2, you get 8. If you multiply 5 by 2 you get 10. A proportional relationship is where you can multiply all the numbers by a certain number to get the answer. In this case, all the numbers in the left column could get multiplied by 2 to get the number in the right column.

Answer:

∠3 and ∠2

Step-by-step explanation:

Adjacent angles are angles that have a common side and common vertex which each other.

The first option is incorrect because they don't share a common side. They do share a vertex but that isn't enough to call them adjacent.

The second option is correct because they share a common side and vertex.

The third option is incorrect because they don't share a common side.

The fourth option is incorrect because they don't share a common side. These two angles are congruent and opposite angles.

Best of Luck!

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

you can only +/- an equation like this with the same square root

Answer:

A

Step-by-step explanation:

the distance between M and point be is 5.5 for the x coordinate and 3 for the y coordinate. to find point b you added 5.5 to to the x and 3 to the y so if you subtract this from point M you get (-5,-5).

Answer:

Perimeter is all sides added together, while Area is one side height times length

Step-by-step explanation:

Since your shape is a square all sides are equal so the equation is the same for all sides

Perimeter = 4z+3+4z+3+4z+3+4z+3 or (4z+3)4

14z+12 <= answer for perimeter

Area = (4z+3) (4z+3)

16z^2+12z+12z+9

16z^2+24z+9 <= answer for area

Answer:

[tex]v=\frac{145}{8}[/tex]

Step-by-step explanation

[tex]\frac{5}{v}=\frac{2}{7.25}[/tex]

[tex]\frac{5}{v}=\frac{2}{\frac{725}{100}}[/tex]

[tex]v=\frac{2}{\frac{5^2*29}{2^2*5^2}}[/tex]

[tex]v=\frac{145}{8}[/tex]

Answer:

6 miles/hr

Step-by-step explanation:

Given:

Top speed of Brand A scooter goes 2 miles per hour faster than Brand B.

Distance traveled by brand A scooter on its top speed in 3 hours = 24 miles

To find:

The rate at which brand B traveled the same distance at its top speed ?

Solution:

Let the top speed/rate of brand B scooter = [tex]x[/tex] miles/hr

According to question:

Top speed/rate of brand A scooter = [tex]x+2[/tex] miles/hr

Formula:

[tex]Distance = Speed \times Time[/tex]

Distance is given to be equal to 24 miles:

24 = ([tex]x+2[/tex]) [tex]\times 3[/tex]  ...... (1)

Solving the above equation by first dividing the equation on both sides with 3:

[tex]\dfrac{24}{3} = \dfrac{(x+2)\times 3}{3}\\\Rightarrow 8 = (x+2)[/tex]

Now subtracting 2 from both the sides:

[tex]\Rightarrow 8-2=x+2-2\\\Rightarrow x=6\ miles/hr[/tex]

Therefore, the answer is:

Top speed of scooter B is 6 miles/hr.

The if-then moves used to solve the equation (1) are:

Dividing by a non zero number on both sides, then subtracting a number on both sides.

Answer:

1950 seconds

Step-by-step explanation:

if sixty seconds are in a minute, then you just multiply 32, the number of minutes by the number of seconds in a minute and add 30.

Answer:

Yes

Step-by-step explanation:

The line of best fit is used in linear regression models to make predictions, the line of best fit gives the relationship between the dependent and independent variables by obtaining the Coefficient of correlation. The Coefficient of correlation is a value which ranges from - 1 to 1. With values close to either - 1 or 1 depicting a strong negative and positive relationship respectively. Hence, with a correlation Coefficient of - 0.86, which signifies a strong negative relationship, then we can go ahead and make prediction using the model.

Answer:

95.44%

Step-by-step explanation:

Mean (m) = 48

Standard deviation (sd) = 9

n = 12

Zscore = (x - m) /sd

X = 30

Zscore = (30 - 48) / 9

Zscore = - 2

X = 66

Zscore = (66 - 48) / 9

Zscore = 2

percentage of daily phone calls numbering between 30 and 66 = P(z < 2) - p(z < - 2)

P(z < 2) = 0.9772

P(z < - 2) = 0.0228

Hence,

0.9772 - 0.0228 = 0.9544

0.9544 * 100% = 95.44

Answer:

-1/4

Step-by-step explanation:

Simply draw a slope triangle

Answer:

its -1/4 which is the third option

Step-by-step explanation:

negative because it's going down, 1/4 because every four blocks to the right it goes down by only one block

16 square feet (also can be written with an exponent 2 as in 16 ft^2)

Cube root of 64 is 4.

Why cube root? Because you need to multiply three numbers to get volume ( length, width, height.)

4x4 is 16.

Area, so you have to add the square feet

16 ft^2

Or

16 square feet
