The value of expression at x = 3 is,
⇒ 30
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 6² + x - x²
Now, We can simplify as;
⇒ 6² + x - x²
⇒ 36 + x - x²
Put x = 3;
⇒ 36 + 3 - 3²
⇒ 36 + 3 - 9
⇒ 36 - 6
⇒ 30
Thus, The value of expression at x = 3 is,
⇒ 30

line k goes through the points ( 8,15) and (-4,9). if line p is parallel to line k, what is the slope of line p?
Answer:
Line p will have a slope of 1/2
Step-by-step explanation:
The slope of line k is
m = ( y2-y1)/(x2-x1)
= ( 9 -15)/(-4 -8)
= -6/-12
= 1/2
If the lines are parallel, they have the same slope
Line p will have a slope of 1/2
Step-by-step explanation:
We can find the slope of a line through the formula
[tex]\frac{y1 - y2}{x1-x2}[/tex]
Where x1 and y1 are the coordinates of the first point, and x2 and y2 are the coordinates of the second point.
So we substitute the values we are given into this formula:
[tex]\frac{15-9}{8-(-4)}[/tex]
and simplify:
[tex]\frac{6}{12}[/tex]
and simplify again:
[tex]\frac{1}{2}[/tex]
And so the slope of line k is 1/2x. Since line p is parallel to line k, the slope of line p is also 1/2x.
What is the maximum number of possible extreme values for the function, F(x)=x^4+x^3-7x^2-x+6?

B. 4
C. 5

Coming from a 6th grader but I hope this is right!
Polynomials of degree greater than 2 can have more than one max or min value. The largest possible number of minimum or maximum points is one less than the degree of the polynomial. The following examples illustrate several possibilities.
since the degree is 4
number of possible extreme values = 4 -1 = 3

Lourdes plans to jog at least 1.5 miles. Write an inequality and solve an inequality to find x, the number of hours Lourdes will have to jog. She is running at 3.75 mph
Answer:
1.5 ≤ 3.75x
Step-by-step explanation:
Given that:
Distance, D to jog is atleast 1.5 miles
D ≥ 1.5 miles
x = number of hours to jog
Jog rate = 3.75 mph
Actual distance covered if jog last for X hours
Actual Distance = speed * time
Actual Distance = 3.75 * x = 3.75x
Hence,
D ≤ Actual distance
1.5 ≤ 3.75x

Answer:
JP = 36
Step-by-step explanation:
Since JN is the entire line, then just divide 54 by 3 which equals to 18, then add 18 + 18 which equals to 36. You want to do this because an entire line segment is in 3 units (JN) , so which mean (JP) is 2/3 or 2 units of 3.

year's fundraising amount. Find last year's fundraising amount.
Please help I have know clue what to do!!
Answer: Hi, sorry if I’m late to answering but the answer is 19
Step-by-step explanation:
You divide each number in the equation by 5. So, 5x divided by 5 = 1. We cannot use 5 divided by 5 because it will equal 1 so we ignore that and go to 95 divided by 5 = 19. Therefore, 19 is your answer!!! (Hope this helped)

Anthony is preparing to paint a large shipping container and needs to calculate the area of the container so he can buy the correct
amount of paint. The equation he uses to find the area, A, in square feet is A = 2(w + hw +1h) where / is the length, w is the width,
and h is the height of the container. The container is 8 feet wide, 12 feet high, and 24 feet long. What is the area of the container
in square feet?
Answer:
1152 square feetStep-by-step explanation:
The dimensions of the container:
w = 8 feet, h = 12 feet, l = 24 feetThe area of the container is:
A = 2(lw + hw + lh)A = 2(24*8 + 12*8 + 24*12) = 1152 square feetWrite the phrase as an expression.

Your friend claims that she has a bag of 30 coins containing nickels, dimes,
and quarters. The total value of the 30 coins is $3. There are twice as many
nickels as there are dimes. Is your friend correct?
9514 1404 393
Answer:
No
Step-by-step explanation:
If all 30 coins were nickels and dimes, there would be 10 dimes and 20 nickels, for a total value of $2.00. Trading a dime and 2 nickels for an equal number of quarters raises the value to $2.00 -0.10 -2(0.05) +3(0.25) = $2.55.
That is, each such trade adds $0.55 in value to the total amount. Since the original difference of $3.00 -$2.00 = $1.00 is not evenly divisible by $0.55, there cannot be twice as many nickels as dimes.
__
For 30 coins, possible numbers of {nickels, dimes, quarters} are ...
{21,2,7}, {18,6,6}, {15,10,5}, {12,14,4}, {9,18,3}, {6,22,2}, {3,26,1}, {30 dimes}
Note that we can have 1.5, 3, or 10.5 times as many nickels as dimes, but not 2 times as many.

Mrs. Goerlich deposited $2,000 into a savings account to save for her son's college tuition. • The account earns simple interest. • She did not make any additional deposits or withdrawals. • At the end of 6 years, the account has a balance of $2,780. What is the annual interest rate on this account?
Answer: 6.5%
Step-by-step explanation:
In 6 years the interest earned is:
= 2,780 - 2,000
= $780
The account earns simple interest which means that it increased by the same rate yearly. Yearly increase is:
= 780/6
= $130
Simple interest rate = Interest payment/ Deposit
= 130/2,000
= 6.5%

Question: Determine The Value Of X.
9514 1404 393
Answer:
x = 78
Step-by-step explanation:
The base angles of an isosceles triangle are congruent, so the sum of angles is ...
x° +x° +24° = 180°
2x +24 = 180 . . . . . collect terms
x + 12 = 90 . . . . . . . divide by 2
x = 90 -12 . . . . . . . . subtract 12
x = 78

Additional comment
The base angle of an isosceles triangle is always the complement of half the third angle. That angle's bisector is an altitude, so divides the isosceles triangle into two congruent right triangles.
