Step-by-step explanation:
Let's solve your equation step-by-step.
2x+1=−x+4
Step 1: Add x to both sides.
2x+1+x=−x+4+x
3x+1=4
Step 2: Subtract 1 from both sides.
3x+1−1=4−1
3x=3
Step 3: Divide both sides by 3.

The original price of a jacket was 72.50$ Maria used a coupon for 20% off to buy the jacket. How much did she pay before tax?
Answer: Maria payed $58.00 for her jacket BEFORE tax.
Step-by-step explanation:
To find the answer to this question, we must first multiply 72.50 by 0.20. After doing so, we get 14.5 (this is the sale money). Finally, we subtract $72.50-14.5 to get out answer, 58 dollars.
You play basketball At your schools indoor stadium. You have two payment options. Option A is to buy a membership card for $20 and pay $2 each time you go to the gym, t. Option B is to pay $4 each time you go. After how many trips to the gym will the cost be the same?
Answer:
10 trips
Step-by-step explanation:
Let the number of trips to the gym be represented by t
Option A is to buy a membership card for $20 and pay $2 each time you go to the gym.
$20 + $2× t
20 + 2t
Option B is to pay $4 each time you go.
$4 × t
= 4t
After how many trips to the gym will the cost be the same?
Option A = Option B
20 + 2t = 4t
Collect like terms
20 = 4t - 2t
20 = 2t
t = 20/2
t = 10 trips.
After 10 trips, the gym cost will be the same.

John has a piece of clay that weighs 12 1/2 pounds. He divides the clay into 5 equal pieces. How much does each piece weigh?
Answer:
2.44
Step-by-step explanation:
12 1/2 / 5 =2.44
sum n=3 ^ infty (2n+5)
find the series shown
=====================================================
Explanation:
We're adding terms in the form (2n+5)
The first term is when n = 3, so
2n+5 = 2*3+5 = 6+5 = 11
The next term is when n = 4, so
2n+5 = 2*4+5 = 8+5 = 13
The next term is when n = 5, so
2n+5 = 2*5+5 = 10+5 = 15
And so on
This means,
[tex]\displaystyle \sum_{n=3}^{\infty} (2n+5) = 11+13+15+17+\ldots[/tex]
which matches with choice C. The three dots indicates the pattern goes on forever.
-------------------
Choice B does not have these dots, so that's why choice B is not the answer. If we replaced the infinity symbol with 7, then choice B would be the answer.
I.e,
[tex]\displaystyle \sum_{n=3}^{7} (2n+5) = 11+13+15+17+19[/tex]
POLYNOMIALS QUESTION!!!
Answer:
The new area of the smaller rectangle is 16 - x² units²
Step-by-step explanation:
The dimensions of the small rectangles are 2 + x and 2 - x
∵ The length of the small rectangle is 2 + x units
∵ The length is adding by 2 units
∴ The new length = 2 + x + 2 = 4 + x units
∵ The width of the small rectangle is 2 - x units
∵ The width is adding by 2 units
∴ The new width = 2 - x + 2 = 4 - x units
∵ Area of the rectangle = length × width
∴ The new area of the smaller rectangle = (4 + x) × (4 - x)
→ Simplify it by multiplying the 2 brackets
∵ (4 + x)(4 - x) = (4)(4) + (4)(-x) + (x)(4) + x(-x)
∴ (4 + x)(4 - x) = 16 + (-4x) + 4x + (-x²)
→ Remember (+)(-) = (-)
∴ (4 + x)(4 - x) = 16 - 4x + 4x - x²
→ Add the like terms
∴ (4 + x)(4 - x) = 16 - x²
∴ The new area of the smaller rectangle is 16 - x² units²
Line v passes through point (6, 6) and is perpendicular to the graph of y = 34x – 11. Line w is parallel to line v and passes through point (–6, 10). Which is the equation of line w in slope-intercept form?
A. y = 34x + 2
B. y = –34x + 2
C. y = 43x + 2
D. y = –43x + 2
A B C OR D WHICH ONE
Answer:
y = (1/34)x + 346/34
Step-by-step explanation:
We are told that; Line v passes through point (6, 6) and is perpendicular to the graph of y = 34x – 11
Now, for a line to be perpendicular to another, it means the slope of one will be the negative reciprocal of the other.
Intercept of y = 34x – 11 will be; m = 34
Thus, slope of v is; -1/34
Now, Line w is parallel to line v and passes through point (–6, 10).
Since the slope of v = -1/34, it means the slope of w will be -1/34 because parallel lines have the same slope.
Thus, using slope intercept form, the equation of line w is;
y - 10 = (-1/34)(x - (-6))
y - 10 = x/34 + 6/34
Multiply through by 34 to get;
34y - 340 = x + 6
34y = x + 346
y = (1/34)x + 346/34
Find the slope of the line that passes through the following pair of coordinates: (15,18) (0,6)
Answer: y= (4/5)x+6
Step-by-step explanation:
(0,6) is the y intercept/b . Use y2-y1 for the slope/m. Y= Mx+b now is y=(4/5)x+6.

In this case, the opportunity cost for (refurbishing the gym, upgrading the computer lab, or getting new instruments.) was ( upgrading the new computer lab hardware, getting new equipment, or getting new instruments?
Answer:
getting new instrument
Explanation:
Note that the term opportunity cost refers to the value or the cost of not selecting/benefitting from the other alternative option.
Comparing both budgets, it is observable that the budget for computer lab hardware was increased by 5%; and that of musical instruments was reduced by 5% according to The Northville School Board order of preference (importance).
Thus, we can say that the board decided to forgo some of the amount spent on musical instruments, but decided to increase spending on computer hardware.
Answer:
In this case, the opportunity cost for upgrading the computer lab hardware was getting new instruments.

to determine the cost, in dollars, to buy xx gallons of paint. Find and interpret the given function values and determine an appropriate domain for the function.
Round your answers to the nearest cent.
f(0)=f(0)=
, meaning the cost of buying
gallons of paint would be $
. This interpretation
in the context of the problem.
f(70)=f(70)=
, meaning the cost of buying
gallons of paint would be $
. This interpretation
in the context of the problem.
f(58.5)=f(58.5)=
, meaning the cost of buying
gallons of paint would be $
. This interpretation
in the context of the problem.
Based on the observations above, it is clear that an appropriate domain for the function is
.
Answer:
[tex]f(0) = 0[/tex]
[tex]f(70) = 16.74[/tex]
[tex]f(58.5) = 15.30[/tex]
[tex]x \geq 0[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2\sqrt x[/tex]
Solving (a): f(0)
[tex]f(x) = 2\sqrt x[/tex]
[tex]f(0) = 2 * \sqrt 0[/tex]
[tex]f(0) = 2 * 0[/tex]
[tex]f(0) = 0[/tex]
Interpretation:
This implies that, the cost of 0 paints is $0
Solving (b): f(70)
[tex]f(x) = 2\sqrt x[/tex]
[tex]f(70) = 2 * \sqrt{70[/tex]
[tex]f(70) = 2 * 8.37[/tex]
[tex]f(70) = 16.74[/tex]
Interpretation:
This implies that, the cost of 70 paints is $16.74
Solving (c): f(58.5)
[tex]f(x) = 2\sqrt x[/tex]
[tex]f(58.5) = 2 * \sqrt{58.5[/tex]
[tex]f(58.5) = 2 * 7.65[/tex]
[tex]f(58.5) = 15.30[/tex]
Interpretation:
This implies that, the cost of 58.5 paints is $15.30
Solving (d): The domain
[tex]f(x) = 2\sqrt x[/tex]
Set the radicand x to [tex]\geq 0[/tex]
i.e.
[tex]x \geq 0[/tex]
Hence:
The domain is [tex]x \geq 0[/tex]

Answer:
Parallel
Step-by-step explanation:
Parallel lines have the same slope, in this equation it is a slope of 5.
The given lines are parallel in nature.
What is slope?Numerical measure of a line's inclination relative to the horizontal.
Equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation.
Given:
y = 5x + 2 and y = 5x – 1
The slope for line 1 is 5.
and, the slope for line 2 is 5.
For, perpendicular line the slope of both lines are negative inverse relation.
But here the slope of both line are same which have parallel nature.
Hence, both lines are parallel in nature.
