Answer:
[tex]7[/tex]
Step-by-step explanation:
So we have the expression:
[tex]|3x-1|[/tex]
And we want to evaluate it for x=-2.
So, substitute -2 for x:
[tex]|3(-2)-1|[/tex]
Multiply:
[tex]=|-6-1|[/tex]
Subtract:
[tex]=|-7|[/tex]
The absolute value of a negative is positive. So:
[tex]=7[/tex]
And we're done!
−16=−4(2x−8) please help
Answer:
x = 6
Step-by-step explanation:
−16=−4(2x−8)
Let's rearrange so solving would be easier.
-4(2x-8) = -16
Let's open the brackets. Please take note of the signs (+) (-).
(-4 * 2x) + (-4 * -8) = -16
-8x + 32 = -16
Subtract 32 from both sides. Please take note of the signs (+) (-).
-8x + 32 (-32) = -16 (-32)
-8x + 0 = = -48
-8x = -48
Divide both sides by -8.
-8x/-8 = -48/-8
x = 6

If EF=6 and EG=21, find the value of FG. The drawing is not to scale. A. 17 B. 15 C. 14 D. 6
Answer:
B
Step-by-step explanation:
EF=6 and EG=21
find the value of FG
6
E-------------F-----------------------------------G
|<-----------------------21---------------------->|
EF + FG = EG
6 + FG = 21
FG = 21 - 6
FG = 15
therefore
the answer to the option is B. 15

Find the area of the rectangle.
2x + 4
4x - 2
Answer:
8x² + 12x – 8
Step-by-step explanation:
From the question given above, the following were obtained:
Length (L) = 2x + 4
Breadth (B) = 4x – 2
Area (A) =..?
The area of a rectangle is given by:
Area (A) = Length (L) × Breadth (B)
A = L × B
Thus with the above formula, we can obtain the area of the rectangle as follow:
Length (L) = 2x + 4
Breadth (B) = 4x – 2
Area (A) =..?
A = L × B
A = (2x + 4) (4x – 2)
Expand
A = 2x(4x – 2) + 4(4x – 2)
A = 8x² – 4x + 16x – 8
A = 8x² + 12x – 8
Therefore, the area of the rectangle is 8x² + 12x – 8

The temperature was 80 C. Then the temperature fell 90 C. What was the temperature after it fell?
Answer:
-10 °C
Step-by-step explanation:
Subtract 90 from 80, since it dropped that much:
80 - 90
= -10
So, the temperature after it fell was -10 °C
Answer: -10 Celcius
Step-by-step explanation:
The tempature was 80 degrees and dropped by ninety, and since it dropped then you must subtract. 80 - 90 is -10 degrees Celcius. The temperature is -10 Celcius.

Andrew has one book that is 237 inches thick and a second book that is 3.56 inches thick. If he stacks the books, about how tall will the stack be? Round to the nearest hundredth.
Anyone know this one?
Answer:
3
Step-by-step explanation:
This is cube root (hence the [tex]\sqrt[3]{}[/tex]).
To find the cube root of a number, we are looking for a number that, when multiplied by itself 3 times, equals the number inside the sign.
So:
[tex]3^x = 27[/tex]
We know that [tex]2\cdot 2\cdot 2 = 8[/tex], so this doesn't work.
We also know that [tex]3 \cdot 3 \cdot 3 = 27[/tex], so this works.
Therefore the cube root of 27 is 3.
Hope this helped!
Answer:
the answer is three
Step-by-step explanation:
If you multiply three by itself three times you will get 27.

16 + 28 + (-42)=? Need help

Hi there!
~
Answer:
[tex]16 + 28 + -42[/tex]
[tex]= 44 - 42[/tex]
[tex]= 2[/tex]
❀Hope this helped you!❀
☽------------❀-------------☾
Answer:
2
Step-by-step explanation:
This is the answer because:
1) First, we have to add 16 and 28 which is 44
16 + 28 = 44
2) Next, we have to add 44 and -42, which will be 2 because whenever we have to add or subtract integers, we are supposed to multiply the signs, and then we have to put the sign of the greater number. In this case, it would be:
44 + (-42) = 44 - 42 = 2
Hope this helps! :D
Solve the following equation: 3x+2=2x-6
Answer:x=-8
Step-by-step explanation:
Jasmine is thinking about buying a car and is comparing two vehicles. One gets 13 miles to the gallon (mpg) and the other agents 26 miles to the gallon. Assuming that she drives 5,000 miles a year, how much money would she save by buying the more fuel efficient car if gas is $3 a gallon?
Answer:
$576.93
Step-by-step explanation:
Car A
13 miles to the gallon (mpg)
13 miles = 1 gallon
Car B
26 miles to the gallon
26 miles = 1 gallon
Car B is more fuel efficient than car A
1 gallon = $3
Assuming that she drives 5,000 miles a year
Cost of buying Car A
5000 miles / 13 miles × $3
= 384.62 × 3
= $1,153.86
Cost of buying car B
5000 miles / 26 miles × $3
= 192.31 × 3
= $576.93
Car A - car B
= $1,153.86 - $576.93
= $576.93
Jasmine will save $576.93 by buying the more fuel efficient car if gas is $3 per gallon

If John pays $144 for 9 pounds of pears, how much is each pound
Answer:
$16 per pound
Step-by-step explanation:
We want to find the price per pound.
Therefore, we must divide the cost by the pounds.
[tex]\frac{cost}{pounds}[/tex]
We know it costs $144 for 9 pounds of pears. Therefore, $144 is the cost and there are 9 pounds.
[tex]\frac{\$144}{9 pounds}[/tex]
Divide.
[tex]\$16 /pound[/tex]
It costs $16 for each pound of pears.

Point b, o, and y are collinear on by, and bo:oy = 1/3. B is located at (4,-2,) o is located at (5,-2) and Y is located at (x,y) determine the value of y
Answer:
The value of the y-coordinate is -2
Step-by-step explanation:
Here in this question, we want to use the section formula to determine the y- coordinates of the line that divides the segment in the ratio 1:3 or 1/3
The formula to use to get the coordinates is;
( (mx2 + nx1) /m + n , (my2 + ny1)/( m + n))
So in this case;
m = 1 n = 3
x1 = 4 , x2 = 5
y1 = -2 , y2 = -2
So substituting these values ( we will only make for the y part since we only need to get the y coordinate)
Hence;
[1(-2) + 3(-2)]/(1+3) = (-2-6)/4 = -8/4 = -2
