The area of a rectangle is 15 square inches. What wil be the area, in square inches, of the rectangle after it is dilated by a
scale factor of 2?

Answer:15/20 3/4

Step-by-step explanation:

Because 3 times 5 =15 and 4 times 5= 20 so that will be 15/20

Then if you multiply 3 and 4 by 1 it will give you 3/4

Answer:

15/20 3/4

Step-by-step explanation:

149 because

3(-7)^2+2 =149

Answer:

y + 2 = -0.069(x-+5)

Step-by-step explanation:

SInce the two lines intersects, we will equate it

Multiply x + 3y = 0 by 4;

4x + 12y = 0

4x-4y-13 = 0,

Subtracts both

12y +4y + 13 = 0

16y = 13

y = 13/16

get x;

x + 3(13/16) = 0

x = -39/16

The point of intersection is (0.8, -2.4) and (-5,-2)

Get the equation;

m = y2-y1/x2-x1

m = -2+2.4/-5-0.8

m = 0.4/-5.8

m = -0.069

Get the equation;

y - y0 = m(x-x0)

y - (-2)= -0.069(x-(-5))

y + 2 = -0.069(x-+5)

Answer:

When x=6 in the domain, then y=26 is the corresponding element in the range of the function f(x)=7x-16.

Step-by-step explanation:

Given the expression

[tex]f(x)=7x-16[/tex]

Given that x=6 is an element in the domain of f(x).

Substituting x=6 in the expression to find the corresponding element in the range.

[tex]f(6)=7(6)-16[/tex]

       [tex]= 42-16[/tex]

       [tex]= 26[/tex]

Thus, the corresponding element in the range is: y=26

Therefore, we conclude that:

When x=6 in the domain, then y=26 is the corresponding element in the range of the function f(x)=7x-16.

Answer:

4 days

Step-by-step explanation:

to find this our you must add 78 and 25 before doing anything as they are both part of the daily pass rates

78 + 25 = 103

now you must divide 350 by 103

350/103 = 3.39805825

because you want to find when the season pass is less expensive than the daily pass you must round up

4 is your answer

The answer will be 2.

If you add 2+2+2 it will equal 6 + the 2 on the scale will be 8 that makes it equal to the other scale

12 boys should be enrolled to make the ratio into 1 : 1

'A ratio is a mathematical expression written in the form of a : b, where a and b are any integers. It expresses a fraction.'

According to the given problem,

Given ratio = 4:7

Total number of students = 44

Let the unknown integer multiplier be x,

⇒ 4x + 7x = 44

⇒ 11x = 44

⇒ x = 4

Number of boys = 4 × 4

                           = 16

Number of girls = 4 × 7

                          = 28

Therefore number of boys to be enrolled = 28 - 16

                                                                     = 12

Hence, we can conclude, 12 boys should be enrolled with the already enrolled 16 so as to make boys : girls as 1 : 1.

The square root of one hundred forty > the square root of one hundred three ninths

In this question, we need to compare the square root of one hundred forty and the square root of one hundred three ninths.

We write the square root of one hundred forty as,

√(140)

The value of  the square root of one hundred forty is,

√(140) = 11.8                        ..............(1)

We write the square root of one hundred three ninths as,

√(11.44)

The value of the square root of one hundred three ninths is,

√(11.44) = 3.4                      ...................(2)

From (1) and (2),

11.8 > 3.4

i.e., the square root of one hundred forty is greater than the square root of one hundred three ninths

Therefore, the square root of one hundred forty > the square root of one hundred three ninths

Based on the angle addition postulate, the measure of angle 1 is calculated as: 88°.

The angle addition postulate states hat the sum of two smaller angles is always the measure of a bigger angle from which the smaller angles are formed from.

Given:

Measure of angle 2 = 45°

Measure of angle XWY = 133°

Therefore:

Measure of angle 1 + 45 = 133 [angle addition postulate]

Subtract 45 from each side of the equation

Measure of angle 1 + 45 - 45 = 133 - 45

Measure of angle 1 = 88°

Therefore, based on the angle addition postulate, the measure of angle 1 is calculated as: 88°.

Answer:

x= -3

y= -6

Step-by-step explanation:

8x - 3y= -6 .........equation 1

-8y + 7y= -18..........equation 2

Using elumination method

Multiply equation 1 by -8 and multiply equation 2 by 8

-64x + 24y = 48

-

64x + 56y =-144

-32y = 192

y = 192/-32

y= -6

Substitute -6 for y in equation 1

8x - 3(-6) = -6

8x + 18= -6

8x= -6 -18

8x=-24

x= -24/8

x= -3

Hence x = -3 and y = -6
