Answer:
y = 7x - 5
Step-by-step explanation:
y = 7x+2 we see the gradient is 7 (x 0) + 2 = Since the line is parallel to y= 7x +2
The new line has a slope of 7 + 2 as the intercept at y.
y - 0 = 7 ( x - 0)
y - 1/7 = x - 0
y = 7x - 5
As 7 -5 = 2
Hence equation of line becomes y=7x.
What is Equation of line?You must ensure that both equations have the same slope in order to find an equation for a line that is parallel to another. The m reflects your slope value in the general equation of a line, y=mx+b.
How to solve?Now given line y=7x+2 ,this line is parallel to another line which passes through origin(0,0)
Hence putting 0,0 in general equation to find equation of parallel line
⇒y=mx+c
⇒0=m(0)+c
⇒0=c
where m=7 as parallel lines have same slope.
Hence equation of line becomes y=7x.

Jose starts with $250 and spends $25 a week. Martin starts with $30 and saves $30 a week. Whe
same amount of money? Use x for time and y for saving.
6 weeks
4 weeks
They will always have the same amount of money
They will never have the same amount of money
Answer:
B) They will have the same amount in week 4.
Step-by-step explanation:
Jose: y = -25x +250
Martin: y = 30x + 30
Plug in 6
Jose: y = -25(6) + 250 y = 100
Martin: y = 30(6) +30 y = 2100
Plug in 4
Jose: y = -25(4) + 250 y = 150
Martin: y = 30(4) + 30 y = 150

Answer:
(- 4, - 3 )
Step-by-step explanation:
Given the 2 equations
- 4x + 9y = - 11 → (1)
- 3x + 7y = - 9 → (2)
Multiplying (1) by 3 and (2) by - 4 and adding will eliminate the term in x
- 12x + 27y = - 33 → (3)
12x - 28y = 36 → (4)
Add (3) and (4) term by term to eliminate x
- y = 3 ( multiply both sides by - 1 )
y = - 3
Substitute y = - 3 into either of the 2 equations and evaluate for x
Substituting into (1)
- 4x + 9(- 3) = - 11
- 4x - 27 = - 11 ( add 27 to both sides )
- 4x = 16 ( divide both sides by - 4 )
x = - 4
Solution is (- 4, - 3 )
Which of the following math skills are useful in planning an effective budget?
Estimating

Answer:
Finding averages.Organizing data.Estimating.Data gathering.Step-by-step explanation:
When we plan an effective budget, we certainly need to gather some data about the theme, which includes, prices, description of the stuff we need. Once we have the data we need, then we must organize it to set priorities, to make the budget effective.
Additionally, estiamting and finding averages are important skills, because we need to estimate how effective is the budget. In fact, maybe we would desing different budgets to compare them and analyse, using averages, which one is the most effective.
What is the area of the triangle below
Answer:
D.) 68 units²
Step-by-step explanation:
The formula for the area of a triangle is:
A = bh/2
where b is the base and h is the height
Substitute the given values into this formula:
A = bh/2
A = (17)(8)/2
Solve:
A = (17)(8)/2
A = 136/2
A = 68
Therefore, the area is 68 square units.

Step-by-step explanation:
Which equation correctly shows how to determine the distance between the points (9, –2) and (6, 3) on a coordinate grid?
Answer:
D = √(6 - 9)^2 + (3 + 2)^2]
Step-by-step explanation:
This is an application of the Pythagoras theorem:
D = √ [(x2 - x1)^2 + (y2 - y1)^2] where the 2 points are (x1, y1) and
(x2, y2).
So in this case we have
D = √[(6 - 9)^2 + (3 - -2)^2]
D = √(6 - 9)^2 + (3 + 2)^2]
Which quantity is proportional to 35/80
Answer:
35/80
u want to find a number that is proportional to 35/80, then all u need is a number that is equivalent...another words, if it is proportional, it is an equivalent fraction to 35/80.
there can be several answers to this...such as 35/80 reduces to 7/16...so 7/16 is proportional....or if u multiply numerator and denominator by the same number, u will find a proportional number...
example :
35/80 * 2/2 = 70/160...this is proportional
35/80 * 3/3 = 105/240...this is proportional
35/80 * 4/4 = 140/320...this is also proportional
and so on....
so without giving us any answer choices, there can be many numbers to choose from

Find the length of the missing side of the triangle shown below. Round to the nearest tenth, if necessary.
Answer:
The length of the missing side is 21.9 m.
Step-by-step explanation:
The Pythagorean Theorem states that a² + b² = c². (a = small side, b = long side, c = hypotenuse). Substituting the values from this triangle into the Pytagorean Theorem equation, we get:
9² + 20² = c²
81 + 400 = c²
481 = c²
√481 = c
21.9 = c

X
1
O D. G(x) =
x + 4
Answer: G(x)= 1/x-4
Step-by-step explanation:
The required function is G(x)=1/(x-4)
What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
The given parent function is
f(x)=1/x
By taking f(x), and applying a left or right and/or up or down transformations to it,
The function could be written using the equation f(x-h)+k.
Doing so will make the graph of the function move h units to the left or right. (Positive or negative) (make sure the operation before the h is subtraction when determining the sign of h)
Also, when finding k (up and down) (positive or negative) apply this function.
Then the new function we get
G(x)=(x-h)+k
As a result, plug in your right 4 units as h, and since you are not needing to move up or down k would be 0.
So, G(x)=1/(x-(4))+0
or simplified,
G(x)=1/(x-4)

an empty 1200 gallon tank is filled with water at a rate of 6 gallons of water per minute. At the same time another 1200 gallon tank full of water is being drained at a rate of 9 gallons per minute how many minutes will it take for the amount of water in both tanks to become the same
Answer: 80 minutes
Step-by-step explanation:
Hi, to answer this question we have to write an equation for each tank:
An empty 1200 gallon tank is filled with water at a rate of 6 gallons of water per minute.
So, the amount of water of the tank is equal to the filling rate, 6 liters per minute (6m)
Tank 1 =0 (empty )+ 6m =6mThe second 1200 gallon tank full of water is being drained at a rate of 9 gallons per minute.
Tank 2 = 1200-9mSo, the amount of water in the tank is equal to the amount of water already in the tank (1200 g), minus the draining rate (9m)
Since both tanks will have the same amount of water:
6m = 1200-9m
Solving for m (minutes):
6m+9m= 1200
15m = 1200
m= 1200/15
m= 80 minutes

-3-Find The Tax
-4-Find The Total
Separate Them by Number Please
(Show work too) Thank you
Answer:
A pair of Nike Air Jordan sneakers cost $139.99.
There is a 35% off sale going on at Foot Locker.
=> Sale price = 139.99 - 139.99 x 35/100 = ~$90.99
Sales tax is 8.125% in Orange County.
=> The tax = 90.99 x 8.125/100 = ~$7.39
The total price is calculated by:
P = The sale price + The tax = 90.99 + 7.39 = ~$98.38
Hope this helps!
:)
Answer: Sale price before tax $90.99
Tax $7.39
Total after tax $98.38
Step-by-step explanation:
Sale price 139.99 x 0.65 = 90.99
Tax 90.99 x 8.125/100 = 7.39
Total 90.99 + 7.39 = 98.38

t=-2
Answer:
One solution: t = -2.
Step-by-step explanation:
To figure out how many solutions an equation has, it would be best to compute the solution first.
Given:
3t + 5 = 4t + 7 // Subtract 3t from both sides.
5 = t + 7 // Subtract 7 from both sides.

Find (gºf)(4) when f(x)
f)(4) when f(x) = 4x - 2 and g(x)
-6x² - 86 - 8.
Answer:
(g°f)(4) = -1296
Step-by-step explanation:
It is given that:
g(x) = -6x² - 86x - 8
f(x) = 4x - 2
First find the equation of (g°f)
(g°f) = g [ f (x) ]
(g°f) = g [ 4x-2 ]
Substitute 4x-2 for x in formula of g(x)
g(x) = -6x² - 86x - 8
g(4x-2) = -6(4x - 2)² -8(4x - 2) - 8
g(4x-2) = -6(16x² + 4 - 2(4x)(2)) - 32x + 16 - 8
g(4x-2) = -96x² - 24 +96x - 32x + 16 - 8
g(4x-2) = -96x² + 64x - 16
(g°f)(x) = -96x² + 64x - 16
Substitute x=4 into the equation:
(g°f)(4) = -96(4)² + 64(4) - 16
(g°f)(4) = -1296
