Step-by-step explanation:

4/5x<=2

x is less than or equal to 2.5

Answer:

Yup, its greater than 0.8

Answer:

Yes

Step-by-step explanation:

0.8 is less than 1 and 6 is greater than one so 6 is greater than 0.8. :)

A

Step-by-step explanation: ITS RIGHTTTTTTTTTTTTTTTTT

Answer:

x=5

y=-5.8

Step-by-step explanation:

4x-3x=1x

1x=5

x=5

8(5)-5y=11

40-5y=11

40-11=29

-5y=29

29/-5=-5.8

y=-5.8

Answer:

(f o g)(4)=27

Step-by-step explanation:

(f o g)(4)=2x+5

f(g(4))=2x+5

f(4²-2(4)+3)=2x+5

f(16-8+3)=2x+5

f(8+3)=2x+5

f(11)=2x+5

f(11)=2(11)+5

f(11)=22+5

f(11)=27

Therefore, (f o g)(4)=27

Answer:

Answer:

-119

Step-by-step explanation:

Substitute a for 2.7 since a = 2.7

Then multiply -20 by 2.7 = -54

Next subtract -54 by 65

Finally, you have your answer!

A=23.04cm² , A=a2=4.82=23.04cm²

Answer: 23.04 cm.

Step-by-step explanation:

To find the area of something, we use the equation l x w, or length x width.

A square has 4 sides, and all 4 sides are equal. If the length of a square is 4.8, then the width is also 4.8 since all 4 sides of a square are equal.

Since we're using the equation l x w to find the area of the square, we have to multiply 4.8 x 4.8.

4.8 x 4.8 = 23.04.

Therefore, the area of the square is 23.04 centimeters!

Answer:

Plot these points

(1,935)

(2,870)

(3,805)

(4,740)

(5,675)

Slope= -65

y intercept = 1000

and what it's saying is that we travel at a speed of 65 units an hour and we start 1000 miles away

Step-by-step explanation:

Just graph these points which you can get by plugging in the numbers

1000-65= 935

(1,935)

1000-65*2=870

(2,870)

1000-65*3= 805

(3,805)

1000-65*4=740

(4,740)

1000-65*5= 675

(5,675)

B:

y= mx+b where m is the slope and B is the y intercept

we can re write the equation as follows

-65x+1000

It's pretty clear that -65 is the slope and 1000 is the y intercept

Answer:

20%

Step-by-step explanation:

Mr. And Mrs. Jenkins wanted to make a down payment of $25,000 on a house. If the house costs $125,000, what percent is this?

The Percentage of the down payment is given as:

Down payment/Cost of the house × 100

Down payment = $25,000

Cost of the house = $125,000

$25,000/$125,000 × 100

= 20%

The percentage is 20%

Answer:

The probability is 1/4

Step-by-step explanation:

So there's 4 possible outcomes. So if you roll the spinner and you can only get one outcome. So it'll be 1/4.

Answer:

P(<3, then 4) = 1/2 x 1/4 = 1/8

Step-by-step explanation:

probability of a number less than 3 would mean landing on a 1 or 2, which has a prob. of 1/2

probability of landing on the number 4 is 1/4

multiply the probabilities

Given:

Point V is located at (-5,3) on the coordinate plane.

It is reflected over the y-axis to create point V'.

Point V' is then reflected over the x-axis to create point V''.

To find:

The location of point V''.

Solution:

We have,

Point V= (-5,3)

If point V reflected over the y-axis, then

[tex](x,y)\to (-x,y)[/tex]

[tex]V(-5,3)\to V'(5,3)[/tex]

If point V' reflected over the x-axis, then

[tex](x,y)\to (x,-y)[/tex]

[tex]V'(5,3)\to V''(5,-3)[/tex]

Therefore, the ordered pair (5,-3) describes the location of V''.

Answer:

5,3

Step-by-step explanation:
