b)2x²+3x-8
Step-by-step explanation:
a) (7z³+4z-1)+(2z²-6z+2)
7z³+2z²-2z+1
b) (5x²-2x-1)-(3x²-5x+7)

For the first one Answer:7z^3 −2z+1+2z^2
Step-by-step explanation:
(7z ^3
+ 4z −1)+(2z^2
− 6z +2)
Combine 4z and −6z to get −2z.
7z3 − 2z −1 + 2z2 +2

Step-by-step explanation:
first of all, g(x) has only negative functional result values (y) except for 0.
and a square is always positive.
so, the only possible right answers are the ones that include a minus ("-") sign.
the graph shows us that g(x) goes through the points (1, -3) and (-1, -3).
so, which equation turns an x = 1 into an y = -3 ?
therefore, the right answer must be D.
g(x) = -3x²
it works for both points :
-3 = -3×1² = -3 correct
-3 = -3×(-1)² = -3×1 = -3 correct

A random survey showed that 35 out of 52 people plan to vote for Mr Powell for Mayor. About how many people voted in the election, if 525 voted for Mr Powell
Answers
Answer:
780
Step-by-step explanation:
35 out of 52 people voted. You’d have to divide the total votes, 525 by the people that voted, so 35 which would equal 15.
Then, multiply 15 by the total of people that didn’t vote, 52, which would equal 780.

The Candela brothers own two pizza restaurants, one on Park Street and one on Bridge Road.
The computer output below summarizes the distribution of weekly revenues at each
restaurantâ€"26 weeks for Park Street and 40 weeks for Bridge Avenue.
Answers
The mean, median and mode are measures of central tendency, that is they tend to indicate the location middle of the data
Required values;
(a) The performance for the week for Park Street
Revenue is Q₂ < $7,500 < Q₃The sales for the week is better than 72.91% of all salesThe performance for the week for Bridge Road
Revenue; Q₂ < $7,100 < Q₃The sale for the week is better than 59.87% of all sales(b) The mean is $3611
The median is $3,600
The standard deviation is $3250
The Interquartile range is $6075
Reason:
The table of values that maybe used to find a solution to the question is given as follows;
[tex]\begin{array}{|l|l|l|}\mathbf{Variable} &\mathbf{Park}&\mathbf{Bridge}\\N&36&40\\Mean&6611&5989\\SE \ Mean&597&299\\StDev&3580&1794\\Minimum&800&1800\\Q_1&3600&5225\\Median&6600&6000\\Q_3&9675&7625\\Maximum&14100&8600\end{array}\right][/tex]
(a) Park Street revenue = $7,500
Bridge Road's revenue = $7,100
The two stores sold close to but below the 75th percentile
Bridge Road revenue;
The z-score is given as follows;
[tex]Z = \dfrac{x - \mu }{\sigma }[/tex]
[tex]Z = \dfrac{7100 - 5,989 }{1794 } \approx 0.6193[/tex]From the Z-Table, we have;
The percentile= 0.7291
Therefore, the sale for the week for Park Street is better than 72.91% of all the salesPark Street revenue;
The z-score is given as follows;
[tex]Z = \dfrac{7500 - 6611}{3580} \approx 0.25[/tex]From the Z-Table, we have;
The percentile = 0.5987
Therefore, the sale for the week is better than 59.87 % of all the sales(b) Given that the operating cost is $3,000, frim which we have;
The subtracted value is subtracted from the mean and median to find the new value
Profit = The revenue - Cost
New mean = 6611 - 3000 = 3611
The new mean = $3,611The new median = 6600 - 3000 = 3600
The new median = $3,600The standard deviation and the interquartile range remain the same, therefore, we have;
The standard deviation = $3,580The interquartile range = 9675 - 3600 = 6075
The interquartile range = 6075Learn more here:

The monthly cost of a certain texting plan is given by the function C(n)= 0.06n +9.95, where C(n) is in dollars and n is the
number of texts sent in a month. Find and interpret C(90)
Monthly Cost of Texting Plan
Ac(n)
Answers
Answer:
C(90) = 15.35
Step-by-step explanation:
Given the function, C(n) = 0.06n + 9.95:
where C = total cost of texting plan
n = number of texts sent in a month
9.95 = flat fee
To find C(90):
Substitute 90 as the input, n, for the function:
C(90) = 0.06n + 9.95
C(90) = 0.06(90) + 9.95
C(90) = 5.40 + 9.95
C(90) = 15.35
C(90) represents the cost of sending 90 texts in a month is $15.35.

3x+1 = 5y+9=61
Step-by-step explanation:
All three of these angles are equal to each other as the figure is a pair of parallel lines with a line through the middle. This means that the angles opposite to each other are equal, thus 61 = 3x + 1. 5y+9 = 61 from the same definition as the lines are parallel. We can also find that it's equal to 61 as 180=119+5y+9.
Thus, x = 20 and y = 52/5

Given m∠LMN=145 what is ∠XMN?
Answers
Answer:
(4x+5)°+(6x-10)°=145°
4x+6x+5-10=145°
10x-5=145°
10x=145+5
10x=150°
x=15
(6x-10)°=(6×15-10)°
=80°
The value of ∠XMN = 80.
What is angle?An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint.
The value of total ∠LMN = 145.
∠LMN = ∠LMX +∠XMN
145 = (4x + 5) + (6x - 10)
145 = 4x + 5 + 6x - 10
145 = 10x -5
10x = 150
x = 15
Substitute the value of x in ∠XMN = (6x - 10)
∠XMN = 6×15 - 10
= 90 - 10
∠XMN = 80
Therefore, the value of the angle ∠XMN = 80.

x = 11
Step-by-step explanation:
1. Because this is a straight angle, (11x + 7)° and (5x - 3)° add up to 180°.
[tex]11x+7+5x-3=180[/tex]2. (Solving)
Step 1: Simplify both sides of the equation.
[tex](11x+5x) + (7-3) = 180[/tex] [tex]16x + 4 = 180[/tex]Step 2: Subtract 4 from both sides.
[tex]16x + 4 - 4 = 180 - 4[/tex] [tex]16x = 176[/tex]Step 3: Divide both sides by 16.
[tex]\frac{16x}{16} = \frac{176}{16}[/tex] [tex]x = 11[/tex]Therefore, x = 11! I hope this helped you.
