Answer:
z+y/5=x or z/5 + y/5 = x
Step-by-step explanation:
z=5x-y
add y to both sides
z+y=5x
divide both sides by 5
z+y/5=x or z/5 + y/5 = x
Solve the absolute value equations algebraically
|m+4|+7=11
Answer:
m=0,-8
Step-by-step explanation:
Rearrange this Absolute Value Equation
|m+4|+7 = 11
Another term is moved / added to the right hand side.
|m+4| = 4 STEP 2:
Clear the Absolute Value Bars
The Absolute Value term is |m+4|
For the Negative case we'll use -(m+4)
For the Positive case we'll use (m+4)
STEP3:Solve the Negative Case
-(m+4) = 4
Multiply
-m-4 = 4
Rearrange and Add up
-m = 8 Multiply both sides by (-1)
m = -8
Which is the solution for the Negative Case
STEP4:Solve the Positive Case
(m+4) = 4
Rearrange and Add up
m = 0
Which is the solution for the Positive Case
STEP5:
Wrap up the solution
m=-8
m=0

Two solutions were found :
m=0,M=-8
What is 3/8 x 2/5 equals to what
Answer:
[tex]=\frac{3x}{20}[/tex]
Step-by-step explanation:
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \:a\cdot \frac{b}{c}\cdot \frac{d}{e}=\frac{a\:\cdot \:b\:\cdot \:d}{c\:\cdot \:e}[/tex]
[tex]=\frac{3x\cdot \:2}{8\cdot \:5}[/tex]
[tex]=\frac{3x}{4\cdot \:5}[/tex]
[tex]\mathrm{Multiply\:the\:numbers:}\:4\cdot \:5=20[/tex]
[tex]=\frac{3x}{20}[/tex]
Answer:
Do you mean 3/8 times 2/5? It equals 3/20
Step-by-step explanation:
So multiple the top numbers together for the top result and multiple bottom numbers for bottom result. 3 times 2 equal 6, 8 times 5 equal 40. the result is 6 over 40. After simplifying, we have 3 over 20 (dividing both 6 and 40 by 2)
A solid metal sphere with diameter 10cm needs to be covered with a protective material which costs £0.29 per cm2. How much will it cost to cover the sphere with the material? Give your answer rounded to 2 DP.
Answer:
1083.45
Step-by-step explanation:
Diameter = 2r
Radius = 5cm because the diameter is 10.
4 pie r^2 is the surface area. = 314.2.
314.2/0.29 = 1083.45 Pounds

When the domain is restricted, you can pick any value to substitute in for the
independent variable.
True
O False
Answer:Therefore, the domain is restricted to non-negative values of x so that the function values will be defined. The variable x is often referred to as the independent variable, while the variable y is referred to as the dependent variable

Help pleasee last question
Answer:
1/5
Step-by-step explanation:
it appears as those two distinct points on the graph are (-3,1) and (2,2)
so take the difference of the y-values and put it over the difference of the x-values to get a fraction to represent the slope
2-1 / 2-(-3) = 1/5
if you start from the point (-3,1) you must rise by one unit and then run five units to the right to get to (2,2)
Mrs. Womack wants to make 22 mini pizzas for her favorite math class party. She
has 18 cups of flour and each mini pizza takes 4 cup of flour. Does she have enough
flour? If not, how much more flour does she need? If so, how much flour will she
have left over?
Answer:
She can only make 4 whole mini pizzas and needs 70 more cups of flour and will not have any leftover after that.
Step-by-step explanation:
18/4= 4.5
22*4=88
88-18= 70
Answer:
No
Step-by-step explanation:
Mrs. Womack need 22 mini pizzas and each requires 4 cups and when you do the math 22 times 4 is 88, and she only has 18 cups so she would only have enough to make 4 full pizzas. So in total she needs 88 cups meaning she needs 70 more.
22x4=88
88-18=70
18÷4= 4.5
Answer:70 more cups are needed

Question 4 options:
x < -2
x > 8
x < 8
x > -2
Answer:
B. X > 8
Step-by-step explanation:
when dividing a negative denominator, you are flipping the sign. if the denominator doesn't have a negative sign, the sign isn't flipped.
steps:
subtract 30 by -18.
Soon you receive -48. Divide that by -6.
The signs soon flip giving you X> 8

X-4/2 = 4x-9/3
A x=-6
B x=-3/5
C x=6/5
D x =6/11
Answer:
x = 6/5
Step-by-step explanation:
x-4 4x-9
------ = ----------
2 3
Using cross products
3 * (x-4) = 2 ( 4x-9)
Distribute
3x-12 = 8x-18
Subtract 3x from each side
3x-12-3x = 8x-18-3x
-12 = 5x-18
Add 18 to each side
-12+18 =5x-18+18
6 = 5x
Divide by 5
6/5 = 5x/5
6/5 =x

How do i find the slope
Answer:
y=1/2x
Step-by-step explanation:
Its a positive slope so you go up 2 then right 4
Answer:
slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (6, 3) ← 2 points on the line
m = [tex]\frac{3-0}{6-0}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
Use the distributive property to remove the parentheses. -6(5y-2u-3)
by multiplying each term in the parentheses by the term outside
-6(5y-2u-3) = (-6 × 5y) + (-6 × - 2u) + (-6 × -3)
= -30y + 12u + 18
Question 1 What is the slope of the line that is represented by the equation y−15=−6(x+7)?
Step-by-step explanation:
Change the equation to the general form [tex]Ax + By + C = 0[/tex].
[tex]y - 15 = - 6(x + 7) \\ y - 15 = - 6x - 42 \\ 6x + y - 15 + 42 = 0 \\ 6x + y + 27 = 0[/tex]
The slope
[tex] = - \frac{A}{B} [/tex]
[tex] = - \frac{6}{1} [/tex]
[tex] = - 6[/tex]
Answer: Slope is -6
Step-by-step explanation:
We want to rearrange the equation to the form of y=mx+b, where m is the slope and b the y-intercept.
y−15=−6(x+7)
y−15=−6x-42
y=−6x-42+15
y = -6x - 27
The slope is -6

Answer:
h(-2) = 32
[tex]\displaystyle\mathsf{h(\frac{20}{7})=-2}[/tex]
Step-by-step explanation:
Given the linear function, h(x) = -7x + 18:
h(-2)In order to evaluate h(-2), simply substitute the value of the given input, x = -2, into the function.
h(x) = -7x + 18
h(-2) = -7(-2) + 18
h(-2) = 14 + 18
h(-2) = 32
Therefore, the output value when x = -2 is: h(-2) = 32.
Find x if h(x) = -2.
This particular problem asks us to find the corresponding domain (x-value) given the range value of y = -2.
Substitute the value of y = -2 into the function to solve for the value of x:
h(x) = -7x + 18
-2 = -7x + 18
Subtract 18 from both sides:
-2 - 18 = -7x + 18 - 18
-20 = -7x
Divide both sides by -7 to solve for x:
[tex]\displaystyle\mathsf{\frac{-20}{-7}\:=\:\frac{-7x}{-7} }[/tex]
[tex]\displaystyle\mathsf{x\:=\frac{20}{7}}[/tex]
Therefore, the value of x when h(x) = -2 is: [tex]\displaystyle\mathsf{h(\frac{20}{7})=-2}[/tex].
What percent of 25 is 10?
10 = x. 25; 40%
10 = x. 25; 250%
25 = x10; 4%
25 = x= 10; 250%
E
Answer:
40
Step-by-step explanation: Make a proportional relationship. Make 25% into a fraction, 25/100. Then make 10 into a fraction using a variable. For example 10/p. Then cross multiply. 100x10=1000. Divide 1000 by 25 and the answer would be 40.
