Answer:
Yes
Step-by-step explanation:
Yes, this is a numerical expression because x represents a number. This number is unknown, so x = 1 --- 5x (1) + 2 is equivalent to 5x + 2. 5x (1) +2 is a numerical expression, SO that means that 5x + 2 is a numerical expression.

The Jackson's dinner cost $125. They left $21.25 as a tip. What was the percentage of the tip? Please explain and help me! THANK YOU!!!
Answer:
17%
Step-by-step explanation:
to find the percentage of something, you have to fill out the following formula:
x/100 = 21.25/125. Basically that is saying that some percent out of 100 is equal to 21.25 out of 125. To solve that, you have to cross multiply:
125x = 2125
then you have to divide, to single out x:
the answer is 17
so it is 17%

Jeremiah's retirement party will cost $16 if he invites 4 guests. What is the maximum number of guests there can be if Jeremiah can afford to spend a total of $20 on his retirement party? Solve using unit rates.
Answer:
5 guests
Step-by-step explanation:
Jeremiah party will chat $16 if he invites 4 guest
The first step is to calculate how much it will cost to feed one guest
$4 = 16 guests
1 guest= 16/4
1 guest = $4
Therefore if Jeremiah can afford to spend $20 then the maximum number of people that will be present can be calculated as
$4 = 1 guest
$20= 20/4
= 5 guests
Hence the maximum number of guest is 5 guests

2. Consider the following graph of a quadratic function.
a Doline the domain
b. Define the range
c. Where is the graph increasing
d. Where is the graph decreasing
. Identify any relative maximums.
1 Identily any relative minimums
10 points!!!
Answer:
Domain is all real numbers.
Range is -3 to infinity that is y >= -3 (that is y -3)
Increasing from x > -4 ( that is from -4 to +infinity) that is to right of -4
Decreasing from x <-4 (that is -infinity to -4) that is to left of -4
This has a minima at x= -4 with y= -3. We can write as (-4, -3)
Maxima is not there as it is going to infinity

you just need to form quadratic equations
Answer:
The value of x is 6
Step-by-step explanation:
The formula of the area of the rectangle is A = l × w, where
l is its lengthw is its widthIn the rectangle ABCD
∵ AB = 2x cm
∴ l = 2x
∵ AD = x cm
∴ w = x
→ Use the formula of the area above to find its area
∵ A = 2x × x
∴ A = 2x²
∵ The area of the shaded region = 50 cm²
→ When the shaded region removed, then the remaining area is the
unshaded region
∵ The area of unshaded region = 22 cm²
∵ The area the ABCD = area the shaded region + area unshaded region
∴ A = 50 + 22
∴ A = 72 cm²
→ Equate the two right side of A
∵ 2x² = 72
→ Divide both sides by 2
∴ x² = 36
→ Take √ for both sides
∴ x = 6
∴ The value of x is 6

Write an equation for the nth term of the arithmetic seqeuence. Then find a10 100,110,120,130...
The 10th term of this arithmetic sequence 100,110,120,130... is 190.
What are arithmetic and geometric sequence?An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference
d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.
In a geometric sequence numbers are written in the same constant ratio(r).
It means every next number is a multiple of a common constant and the previous number.
r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.
Given, An arithmetic sequence 100,110,120,130...
First term a₁ = 100, Common difference(d) = 130 - 120 = 120 - 110 = 10.
We know nth term of an arithmetic sequence is aₙ = a₁ + (n - 1)×d.
aₙ = 100 + (n - 1).10.
aₙ= 100 + 10n - 10.
aₙ = 10n + 90
So, the 10th term a₁₀ = 100 + (10 - 1).10 = 100 + 90 = 190.

Please help!! Will appreciate. If you don’t know/ unsure don’t answer please
Answer:
The correct answer is graph B.
Hope This Helps! Sorry for late answer!
Answer:
its A because because the slope of the y-intercept is on the possative base towards the iquantities which is to be a posative number, in that case the y-intercept adds a 1 to the x which would lead towards the negative side therefor your answer will be y < -x -2

A rock is thrown straight up from the top of a bridge that is 75 ft high with an initial velocity of 32 ft/s. The height of the object can be modeled by the equation s(t) = -16t2 + 32t + 75. Determine the time(s) the ball is lower than the bridge in interval notation.
In two or more complete sentences, explain why (-∞,0) is not included in the solution.
The ball is lower than the bridge at the interval [2, 3.385] and (-∞,0) contains negative values
How to determine the time the balloon lower than the bridge?The equation of the function is given as
h(t)= -16t^2 + 32t + 75
The above equation is a quadratic equation
When the balloon is less than the bridge i.e. a height of 75 feet, we have
h(t) < 75
So, we have the following equation and inequality
h(t)= -16t^2 + 32t + 7
h(t) < 75
Next, we plot the equation and inequality on a graph (see attachment)
The equations intersect at
t = 0 and t = 2
Remove when t = 0
t = 2
The ball hits the ground at t = 3.385
So, the interval is [2, 3.385]
Also, (-∞,0) is not included in the solution because time cannot be negative
