what is the additive inverse of -15 and 15
Answer
-15
Step-by-step explanation:
Factor out the greatest common factor of Given the expression: 4x^10 − 64x^2
Part A
4x10 – 64x2
= 4x2 * x8 – 4x2 * 16
= 4x2 * (x8 – 16) by distributive property
Part B
x8 is (x4)2 and 16 = 42 so a difference of squares is seen in the parentheses. The pattern a2 – b2 = (a + b)(a – b) can be used.
4x2 * (x8 – 16)
= 4x2 * (x4 + 4) * (x4 – 4)
x4 = (x2)2 and 4 = 22 so there is another difference of squares in the last factor. Use the pattern again.
= 4x2 * (x4 + 4) * (x2 + 2) * (x2 – 2)
Answer:
Below.
Step-by-step explanation:
The GCF = 4x^2
So its 4x^2(x^8 - 16)
This can be further factored
= 4x^2(x^4 - 4)(x^4 + 4)
= 4x^2(x^2 - 2)(x^2 + 2)(x^4 + 4)

Which expressions are equivalent to Negative 9 (two-thirds x + 1)? Check all that apply. − 9 ⋅ ( 2 3 x ) + 9 ( 1 ) − 9 ⋅ ( 2 3 x ) − 9 ( 1 ) − 6 x + 9 − 9 ⋅ ( 2 3 x ) + 1 − 6 x − 9 − 6 x + 1
Answer:
•(-9 × 2x/3 + 1 × -9)
•-6x - 9
Step-by-step explanation:
Which expressions are equivalent to Negative 9 (two-thirds x + 1)?
Check all that apply.
Negative 9 (two-thirds x + 1) can be expressed as:
-9(2/3x + 1)
Expanding the brackets
(-9 × 2x/3 + 1 × -9)
-6x - 9
Therefore, the expressions that are equivalent to Negative 9 (two-thirds x + 1) is:
•(-9 × 2x/3 + 1 × -9)
•-6x - 9
Answer:

Answer:
4th option OR last option
Step-by-step explanation:
Ok so I think it means hexagon not heptagon since I have never heard of heptagon. Just confirm that with your teacher if it is hexagon or heptagon.
Hexagon = 6 sides
This means that it is not second option. Nor it is the third option since it said that it should be more than 6 sides. Now we are left with 1st and 4th option. It also mentioned that all opposite sides should be parallel. Looking at the first option, not all sides are parallel. Some are big and some are small. This remains with the last option which is the 4th option.
Hope this helps, thank you !!

Mr. Strand mowed 2/5 of his lawn. His son mowed 1/4 of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?
Answer: Mr. Strand mowed most of the lawn, and 7/20 of the lawn still needs to be mowed.
Step-by-step explanation:
Part 1:
We can use change the fractions so that they have equivalent denominators. The Least Common Denominator that the two fractions have is 20.
2/5 = 8/20.
1/4 = 5/20.
Because of this, Mr. Strand, who mowed 2/5 of the lawn, mowed most of the lawn.
Part 2:
8/20 + 5/20 = 13/20. Therefore, 7/20 of the lawn still needs to be mowed.
In conclusion, Mr. Strand, who mowed 2/5 of the lawn, mowed most of the lawn. 7/20 of the lawn still needs to be mowed.
Answer:
Step-by-step explanation:
0.65 of the lawn was mowed

What is the y-intercept of the line 3x – 4y = 24?
(-6, 0)
(0, -6)
(8, 0)
(0, 8)
Answer:
(0, -6)
Step-by-step explanation:
To find the y-intercept(s), substitute in 0 for x and solve for y.
3 × 0 - 4y = 24
y = -6

seeta devi has rs 9 in fifty-paiseand twenty fiv-paise coins. She has twice as many twenty-five paise coins as fifty-paise coins.How many coins of each kind does she have?
Answer:
50 paise coin = 9
25 paise coin = 18
Step-by-step explanation:
Let :
Number of fifty paise = x
Number of 25 paise = y
50x + 25y = 900 - - - (1)
y = 2x - - - (2)
50x + 25(2x) = 900
50x + 50x = 900
100x = 900
x = 900/100
x = 9
y = 2x
y = 2(9)
y = 18
Solve each system by substitution.
y=-4x-9 y=3x+19
Answer:
x=-4, y=7
Step-by-step explanation:
According to the first equation, y = -4x - 9, so we can substitute y in the second equation for -4x - 9.
y = 3x + 19
-4x - 9 = 3x + 19
Add 9 to both sides
-4x = 3x + 28
Subtract 3x
-7x = 28
Divide by -7
x = -4
Plugging this into the equation, we have:
y = -4x - 9
y = -4(-4) - 9
y = 16 - 9
y = 7
12. In y > x + 4, where can we find the solution set?
A. above the line
C. in the line
B. below the line
D. no solution set

luca sells muffins and juice boxes. muffins are $1.50 each and jucie boxes are $1.25 each. write an algebraic expression for the total income luca received from the sale of muffins and juice boxes
Answer:
1.5m+1.25j
Step-by-step explanation:
m equals the number of muffins sold, and because each muffin sells for $1.50, 1.5m represents the income made from the muffins.
Same thing with the juice boxes, j equals the number of juice boxes sold, and because each juice box sells for $1.25, 1.25j represents the income made from the juice boxes.
Add the income from both of them to get the total income, and you get 1.5m+1.25j.
