Answer:
False
Step-by-step explanation:
[tex](-x)^{6}[/tex] = [tex]x^{6}[/tex]
- [tex]x^{5}[/tex] = - [tex]x^{5}[/tex]
Thus
[tex](-x)^{6}[/tex] ≠ - [tex]x^{5}[/tex]
During the summer months the water level in Marthas pool decreases by about 1/2 inch each day due to evaporation which equation shows the approximate total change in inches to the water level in a pool after 30 summer days
Answer:
Option B (second one to the right)
Step-by-step explanation:
Solving this equation:
-1/2(30)= -15
-1/2 x 30 = -15
(2 days = 1 inch lost)
2(4x - 3)=3(x+8)
The equation above is the problem I’m stuck on, I’m in algebra two and it’s been awhile since we’ve gone over this type of equation.
Answer:
x = 6
Step-by-step explanation:
2(4x - 3) = 3(x + 8)
1. Distribute the 2 and 3 into the parentheses.
2(4x) + 2(-3) = 3(x) + 3(8)
= 8x - 6 = 3x + 24
2. Subtract 3x from both sides.
8x - 3x - 6 = 3x - 3x + 24
= 5x - 6 = 24
3. Add 6 on both sides.
5x - 6 + 6 = 24 + 6
5x = 30
4. Divide by 5.
5x ÷ 5 = 30 ÷ 5
x = 6
Hope that helps.
Lucy is going to the grocery store. She will buy 5 items. Every item she will buy is $2. Afterward, she will buy herself a milk shake for $3. How much will she spend at the store?
Find the product of (x + 5)(x − 5).
Answer:
x² - 30 + 5x
Step-by-step explanation:
(x + 5)(x − 5)
=x(x − 5)+5(x − 5)
=x² - 5 + 5x - 25
=x² - 30 + 5x

What are the steps to solving this limit?
Answer:
lim(x---->0) = -5
Step-by-step explanation:
first: sin(x-π/2)= -cosx
so the equation will be :
lim(x---->0) = [-6cos(ax)-1}/cosx
solve :
lim(x---->0) = [-(6cos(a(0))-1}/cos(0)
cos0=1
lim(x---->0)=(-(6(1)-1)/1
lim(x---->0)=-6+1/1
lim(x---->0)=-5
Polynomials: I’ll give brainliest. What is the perimeter of this?
2(5x - 4)
Step-by-step explanation:Perimeter formula
P = 2l + 2w
P = 2(3x - 5) + 2(2x + 1)
= 6x - 10 + 4x + 2
= 10x - 8
= 2(5x - 4)
What is the value of s in the equation 3r= 10+5s when r = 10
Answer:
s = 4
Step-by-step explanation:
Given: 3r = 10+5s
Fill in r: 3(10) = 10 + 5s
Multiply: 30=10+5s
Subtract: 30-10=5s
Divide: 20/5=s
Answer: 4=s
Prove that if 5(m - 1) = -25, then m = -4.
Answer:
The equation is true
Step-by-step explanation:
First, input -4 instead of m in the equation:
5(-4 - 1) = -25
Then, distribute:
-20 - 5 = -25
Finally, simplify:
-25 = -25
This equation is true, and that's how you prove it.
Hope this helps!
Answer:
M= -4
Step-by-step explanation:
1. Distribute the 5 into the parentheses
5m-5=-25
2. Now add 5 on both sides
5m=-20
3. Now divide 5 by -20
m=-4
if a+b= -1 then the value of a^3+b^3 - 3ab= ?
Answer:
-1
Step-by-step explanation:
[tex](a + b)^{3} = {a}^{3} + {b}^{3} + 3ab(a + b) \\ ( - 1)^{3} = {a}^{3} + {b}^{3} + 3ab( - 1) \\ - 1 = {a}^{3} + {b}^{3} - 3ab\\ \\ \huge \red{ \boxed{{a}^{3} + {b}^{3} - 3ab = - 1}}[/tex]

Answer:
400 + 50 + 6 + 0.8 + 0.01
Step-by-step explanation:
This is the answer because:
1) Expanded form means to write a number with its full value. It is shown as a sum of each digit multiplied by its matching place value
2) Therefore, the answer is 400 + 50 + 6 + 0.8 + 0.01

(1/4)^-3/2. The topic is indices.
Answer:
8
Step-by-step explanation:
The minus turns the base upside down
(1/4)^-3/2 = 4^(3/2)
The square root of 4 is 2
2^3 = 8
So the answer is 8.

math 1 work it out please w-2+2w=6 + 5w
Answer:
w = -4
Step-by-step explanation:
w - 2 + 2w = 6 + 5w
Add 2 to both sides.
w + 2w = 8 + 5w
Subtract w from each side.
2w = 8 + 4w
Subtract 4w from each side.
-2w = 8
Divide.
w = -4
When cut into 16 equal slices, each slice is 1/16 of the pizza. Express how much of the plzza 8 of these slices would be in decimal form.
Answer:
the answer is 0.5, or about 50%
Step-by-step explanation:
If 8 slices are being take out of 16, divide the taken pieces by the total pieces, and it would be half or 0.5.
Hope this helps
Answer: 0.5
Step-by-step explanation: because if the pizza is 8 slices that would be the half of the original number of slices it was, so therefore, it would be rounded to 0.5, or 50%- half the pizza
Solve for x in simplest form. 9=8/5(x+5)
Answer:
5/8 =x
Step-by-step explanation:
9=8/5(x+5)
Multiply each side by 5
5* 9=5*8/5(x+5)
45 = 8(x+5)
Distribute
45 = 8x+40
Subtract 40 from each side
45-40 = 8x+40-40
5 = 8x
Divide each side by 8
5/8 = 8x/8
5/8 =x

answer this equation-3x+2<8
Answer:
x > -2
Step-by-step explanation:
-3x+2<8
Subtract 2 from each side
-3x+2-2<8-2
-3x<6
Divide each side by -3, remembering to flip the inequality
-3x/-3 > 6/-3
x > -2
Hey there!☺
[tex]Answer:\boxed{x>-2}[/tex]
[tex]Explanation:[/tex]
[tex]-3x+2<8[/tex]
Let's subtract 2 from both sides of the inequality.
[tex]-3x+2-2<8-2\\-3x<6[/tex]
Now divide both sides by -3.
[tex]\frac{-3x}{-3}<\frac{6}{-3}[/tex]
Simplify 6/-3. Also remember that dividing a positive with a negative will give us a negative.
[tex]6/-3=-2[/tex]
[tex]x>-2[/tex]
