2w + y = 6
a. Find y if w = -4
b. Find y if w = 10
Answer:
a. Find y if w = -4 --- y = 14
b. Find y if w = 10 --- y = -14
Step-by-step explanation:
This is all about substitution!! For question a, we need to substitute "w" with "-4" ...
2 (-4) + y = 6
We know that a positive time a negative equals a negative...so 2 · -4 is -8.
-8 + y = 6
Now let's add 8 on both sides to isolate the variable...which equals to
y = 14
Onto question b...We substitute w with 10.
2 (10) + y = 6
= 20 + y = 6
Subtract 20 from both sides to isolate "y"
y = -14
Hope this helpsss :D
Determine whether the equation is a linear equation in two variables. 5y = x - 5
Answer:
Yes
Step-by-step explanation:
start with 5y=x-5
divide both sides by 5 to get:
y= x/5 - 1
since a linear equation is represented by y=mx+b, and this can be represented in that form, this is a linear equation.

Does (5, 4) make the equation y = –7x true? Yes Or No
Answer:
No
Step-by-step explanation:
Given point ,
(5,4)Substitute ,
y = -7x 4 = -7*5 4 = -35 ( Not true )Answer:
No
Step-by-step explanation:
Substitute the x- coordinate into the equation and if the value equals the y- coordinate then it makes the equation true.
y = - 7(5) = - 35 ≠ 4
Thus (5, 4 ) does not make the equation true

Solve the following: 15+6h=45+8h
1: h= 28
2: h= -30
3: h= 15
4: h= -15
Step-by-step explanation:
→ 15 + 6h = 45 + 8h
→ -8h + 6h = 45 - 15
→ -2h = 30
→ h = 30/-2
→ h = -15

Find the surface area and the volume of the prism .
Answer:
[tex]14 + 4 + 5.5 + 3 + 5.5 {?}^{2} [/tex]
Answer:
Step-by-step explanation:
We have 2 congruent large prisms and one small one.
Volume of a large one= 2*2*14 = 56 cm^3.
Volume of smaller one = 4*3*2 = 24 cm^3.
So volume of the whole prism
= 2*56 + 24
= 136 cm^3.
Surface area of a large one = 3*2*14 + 2*2*5.5 + 2*2*2 = 114
Surface Area of smaller one = 4*3*2 + 2*2*4 = 40
So surface area of the whole prism
= 2 * 114 + 40
= 268 cm^2.

A married man filing separably with a taxable income of $130,000. Compute the tax owned (look at chart)
--PLEASE show work
First, find the tax rate for a person whose taxable income is $130,000. By looking at the table, you can see the tax rate is 33%. To find the total tax, multiply 33% by $130,000.
[tex]0.33 \times 130000 = 42900[/tex]
Thus, the tax this person has to pay is $42,900.
According to the laws of physics, the weights of objects on the Earth are proportional to their weights on the Moon. A boy who weighs 66 lb on Earth weighs 10.92 lb on the Moon. How much will a man who weighs 185 lb on Earth weigh on the Moon? Round your answer to the nearest tenth.
A man who weighs 185 lb on Earth weighs 30.8 lb on the Moon
Two variables are said to be directly proportional if as one variable increases/decreases, the other variables does the same by the same amount.
Let y represent the weight of object on earth and x represent the weight of object on the moon.
y ∝ x
y = kx
When y = 66, x = 10.92, hence:
66 = 10.92k
k = 6
When y = 185 lb:
185 = 6x
x = 30.8 lb
A man who weighs 185 lb on Earth weighs 30.8 lb on the Moon

X - intercepts: (1, 0) and (-8, 0)
Y - intercept: (0, -8)
