fx) = -3x² + 2x - 7, then f(-1) =
Given:
The function is
[tex]f(x)=-3x^2+2x-7[/tex]
To find:
The value of f(-1).
Solution:
We have,
[tex]f(x)=-3x^2+2x-7[/tex]
Putting x=-1, we get
[tex]f(-1)=-3(-1)^2+2(-1)-7[/tex]
[tex]f(-1)=-3(1)-2-7[/tex]
[tex]f(-1)=-3-9[/tex]
[tex]f(-1)=-12[/tex]
Therefore, the value of f(-1) is -12.

8x+12x=180
Step-by-step explanation:
Hank is correct because the angles that are given are supplementary so they are going to add up to 180. Jill is incorrect because the angles are not congruent
This is the correct answer once again because the angles are supplementary so the two added with equal 180

Q1x = 113° as alternate exterior angles are equalQ2Parallel lines have same slope
The given line y - 2x = 8, in slope-intercept form it is:
y = 2x + 8The slope is 2 and the first line has same slope.
Option A. y = 2x + 5Q3Supplementary angles sum to 180°°
Supplement of ∠R is:
180° - 132.6° = 47.4°2x + 3y = 10
In the xy-plane, the graph of which of the following equations is perpendicular to the graph of
the equation above?
•y=-3/2x-10 •y=-2/3x+10 •y=2/3x+10 •y=3/2x-10
The graph formed by equation y= -2/3x+10 will be perpendicular to the graph by equation y=3/2x-10.
What is the slope of any line?A line in the form of ax + by + d = 0 will be a linear equation and if we convert it into the form of y = mx + c where m will be the slope of that equation.
If two lines are perpendicular to each other then the product of their slope of them will be (-1).
⇒ m₁ ₓ m₂ = -1
The slope of line 2x + 3y = 10 will be -2/3
To be any line perpendicular whose slope m with the 2x + 3y = 10
⇒ -2/3 × m = -1
⇒ m = 3/2 so the slope of that line should be 3/2
Hence, line y=3/2x-10 will be perpendicular to the 2x + 3y = 10.

If EFGH is an isosceles trapezoid , EH = 4x-27, FG = x + 9 , EG = 3y + 19 and FH=11y-21, solve for x and y.
Answer: X = 12, Y = 5
Step-by-step explanation:
4x-27 = x+9
+27 +27
4x = x + 36
-x -x
3x = 36
3x/3 = 36/3
X = 12
3y + 19 = 11y - 21
+21 +21
3y + 40 = 11y
-3y -3y
40 = 8y
40/8 = 8y/8
Y = 5
The values of x and y are 12 and 5, respectively
The given parameters are:
EH = 4x-27FG = x + 9EG = 3y + 19FH= 11y - 21The slant sides of an isosceles trapezoid are equal.
So, we have:
[tex]EH =FG[/tex]
This gives
[tex]4x - 27 = x + 9[/tex]
Collect like terms
[tex]4x - x = 27 + 9[/tex]
[tex]3x = 36[/tex]
Divide through by 3
[tex]x = 12[/tex]
Also, the diagonals of an isosceles trapezoid are equal.
So, we have:
[tex]EG = FH[/tex]
This gives
[tex]3y + 19 = 11y - 21[/tex]
Collect like terms
[tex]11y - 3y =19 + 21[/tex]
[tex]8y = 40[/tex]
Divide through by 8
[tex]y = 5[/tex]
Hence, the values of x and y are 12 and 5, respectively

Which statement is true about the data sets of two sets of quiz scores?
Sample A: 5, 5, 5, 5, 5 Sample B: 2, 2, 2, 2, 17
Select one:
Samples A and B have the same mean, but Sample A has a smaller median than Sample B.
Samples A and B have the same median, but Sample A has a larger mean than Sample B.
Samples A and B have the same median, but Sample A has a smaller mean than Sample B.
Samples A and B have the same mean, but Sample A has a larger median than Sample B.
Answer: Samples A and B have the same mean, but Sample A has a larger median then Sample B.
Step-by-step explanation:
The median is the middle number in the sequence.
To find the median, place the numbers in order. Then take away, or cross out, one number from each side. Keep going until you are down to one or two numbers. If there is only one number left, that’s your median. If two, add the numbers together and divide by 2.
The mean is the average. To get the mean you add up all the values and subtract that sum by how many numbers there are in the sequence.
Option D is correct for the given conditions, Samples A and B have the same mean, but Sample A has a larger median than Sample B.
What are measures of central tendency?The descriptive summary of a data set is known as the central tendency in statistics. It reflects the center of the data distribution through the use of a single number from the dataset. Additionally, it only provides a summary of the dataset rather than information on specific data within the dataset. In general, several statistical metrics can be used to determine a dataset's central tendency.
Given the data sets of two sets of quiz scores,
Sample A = 5, 5, 5, 5, 5
sample B = 2, 2, 2, 2, 17
mean is the average of total samples,
mean of sample A = (5 + 5+ 5 + 5 + 5 )/5
mean of sample A = 5
Mean of sample B = (2 + 2 + 2+ 2 + 17)/5
mean of sample B = 5
since the mean of both sample are same,
median is the central digit of sets
median of A is 5 and the median of B is 2,
so the median of sample A is larger than sample B.
Hence option D is correct.

Answer:
KA = 28
∠KBL = 90°
Step-by-step explanation:
KA = KB (both are radii)
KB = 28, so KA = 28
∠KBL = 90° because tangents are perpendicular to the radius

Answer:
let a, c represent costs for adults and children, respectively12c+3a=162; 8c+3a=122Step-by-step explanation:
You are asked only for the setup, not the solution.
I find it convenient to use variable names that remind me of what they stand for. Here, we're asked for the admission prices for adults and children, so 'a' and 'c' are convenient variables to represent those values.
Let a represent the admission price for an adult.
Let c represent the admission price for a child.
__
The first sentence gives a relation between the numbers and the total cost:
162 = 12c +3a
The second sentence gives a different relation:
122 = 8c +3a
These are the "system of equations."
_____
You aren't asked for the solution, but it is (a, c) = (14, 10). It can be found easily by subtracting the second equation from the first.
