Evaluate the expression when m=3. m 2 - 5m + 7​

Answers

Answer 1

Answer:

-2

Step-by-step explanation:

Substitute 3 for m: (3)2 - 5(3) + 7

Simplify: 6 - 15 + 7

Follow PEMDAS and subtract 6 from 15: -9 + 7

Add: -2

Hope this helps ^-^

Answer 2

You said m = 3.

Replace every m you see with 3.

m^2 - 5m + 7

(3)^2 -5(3) + 7

9 - 15 + 7

-6 + 7 = 1

Answer is 1.

Step-by-step explanation:

Step 1: Define

7a + 42 + 8 < -10 + 9a - 64a

Step 2: Solve for a

Combine like terms (a):                                                                                    7a + 42 + 8 < -10 - 55aCombine like terms:                                                                                         7a + 50 < -10 - 55a[Addition Property of Equality] Add 55a on both sides:                                62a + 50 < -10[Subtraction Property of Equality] Subtract 50 on both sides:                      62a < -60[Division Property of Equality] Divide 62 on both sides:                               a < -30/31

Here we see any number a less than -30/31 would work as a solution to the inequality.

the formula of finding a polygon's area is a=bh(1/2)

Example

on the chart it says base 4 and height 6 = an area of 12

which is saying 24 divided by 2 or 1/2 = 12

Plz only find the shaded area only I would appreciate if you did this on paper and showed all steps

Answers

The area of the shaded portion is 106 square m. I got this number by finding the area of the WHOLE figure (120 because that’s what 10 times 12 equals) then I subtracted that by the area of the white portion (14 because 7x2 equals that). Then I just subtract 14 from 120 and get 106. Hope this helps

9. C. 35 + 0.12x = 44.36

10. C. The system has no solution since the second equation is equal to 0

11. A. 32

Step-by-step explanation:

9. The Hill family drove for 78 miles

The rental agency chargers a weekend fee of $35.00 and 12 cents per mile

Convert cents to dollars

1 cent = 0.01 dollar  

∴, 12 cent = 12 x 0.01 = 0.12 dollar

Therefore,  total bill amount = 35 + 0.12 per mile

Let "x" be the number of miles driven

Final bill was $ 44.36

44.36 = 35 + 0.12x  

0.12x = 44.36 - 35  

0.12x = 9.36

Divide both sides of the equation by 0.12

x = 78

C.f(x) = x - (-1)
D.f(x) = -x - 1

Answers

Answer:

The answer is D

Step-by-step explanation:

Since the input is -6, you input it into the equation. That would make it f(-6)=-(-6)-1 which would be equivalent to f(-6)=6-1 , as the negatives at the beginning of the equation cancel each other out and make it positive. Then you solve and get 5, which is your output. Hope I could help :)

The formula for the volume of a rectangular prism is V=l×w×h. Multiply the length times the width times the height to write a simplified expression in standard form to represent the volume of the box.

Answers

Answer:

Volume of box= Box Area * Box height

Step-by-step explanation:

If the box has equal sides then the l=w=h length is equal to height and both are equal to width so this can also be written as l=l=l or

Volume= length * width * height

V= l*w*h

V= l*l*l

V= l³

or  if the three sides are not equal this can also be written as

Volume of box= Box length * Box width * Box height

If we observe closely we find that length * breadth gives the area so the volume of the box can also be written as

Volume of box= Box length * Box width * Box height

Volume of box= Box Area * Box height

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $6500 to rent trucks plus an additional fee of 175.25 for each ton of sugar. The second company charges $5696 to rent trucks plus an additional fee of 225.50 for each ton of sugar.
For what amount of sugar do the two companies charge the same?
What is the cost when the two companies charge the same?

Answers

Answer:

14 tons

$3,860.50

Step-by-step explanation:

Let x = the amount of sugar transported.

First company:

The cost is $3157 truck rental plus $50.25 per ton of sugar.

Total cost = 3157 + 50.25x dollars

Second company:

There is no charge for truck rental, but it costs $275.75 per ton of sugar.

The total cost is

275.75x

When the two costs are the same, then

275.75x = 3157 +50.25x

225.5x = 3157

x = 14 tons

The total cost is 275.75*14 = $3,860.50
