Answer:
mid point (x,y) = M (18, 24)
let J (- 4, - 2) be ( x1, y1)
L(a,b) be (x2,y2)
using midpoint formula
(x,y) = [(x1+x2)/2, (y1 + y2)/2]
or, (18, 24) = [(-4+a)/2, (-2+b)/2]
comparing corresponding element we get
18 = (-4+a)/2 24 =(-2+b)/2
or 36 = -4+ a or 48 = -2 +b
or a = 40 or b= 50
L(40,50)

What happens to the copy when it is created with a scale factor greater than 1? Less than
1? Exactly 1?
Answer:
When a figure is scaled by a scale factor greater than 1, the copy is larger than the original. When the scale factor is less than 1, the copy is smaller. This means that triangles and are scaled copies of each other.

If -2 and 3 are zeroes of quadratic polynomial xsquare + (a+1)x+b then find the value of and b
Answer:
a = - 2, b = - 6
Step-by-step explanation:
Substitute the values of the zeros into the polynomial and equate to zero.
x² +(a + 1)x + b
x = - 2 → (- 2)² - 2(a + 1) + b = 0 , that is
4 - 2a - 2 + b = 0
2 - 2a + b = 0 ( subtract 2 from both sides )
- 2a + b = - 2 → (1)
x = 3 → 3² + 3(a + 1) + b = 0, that is
9 + 3a + 3 + b = 0
12 + 3a + b = 0 ( subtract 12 from both sides )
3a + b = - 12 → (2)
Subtract (1) from (2) term by term to eliminate b
5a = - 10 ( divide both sides by 5 )
a = - 2
Substitute a = - 2 into either of the 2 equations and evaluate for b
Substituting into (2)
3(- 2) + b = - 12
- 6 + b = - 12 ( add 6 to both sides )
b = - 6
Thus a = - 2 and b = - 6

find the distance between (-6,4) and (-2,1)
Answer:
[tex]d=2.65[/tex]
Step-by-step explanation:
Distance Formula: [tex]d=\sqrt{(x_2-x_1)^2-(y_2-y_1)^2}[/tex]
Simply plug in your 2 coordinates into the formula to find distance d:
[tex]d=\sqrt{(-2-(-6))^2-(1-4)^2}[/tex]
[tex]d=\sqrt{(-2+6))^2-(-3)^2}[/tex]
[tex]d=\sqrt{(4)^2-9}[/tex]
[tex]d=\sqrt{16-9}[/tex]
[tex]d=\sqrt{7}[/tex]
[tex]d=2.65[/tex]
13/11 = x/9 round your answer to the nearest tenth
Answer:
x ≈ 10.6
Step-by-step explanation:
Given
[tex]\frac{13}{11}[/tex] = [tex]\frac{x}{9}[/tex] ( cross- multiply )
11x = 117 ( divide both sides by 11 )
x ≈ 10.6 ( to the nearest tenth )

Answer:
a 10.21
Step-by-step explanation:
because 20 - 9.79 = 10.21
Answer:
the ans in the third one,
10.21, it shows the change
Step-by-step explanation:
20.00=c+9.79
so Pablo has 20.00 and he has to use 9.79
so if u add the change and the money he has to use, will be the money he has right now
so c = the change
so...
20.00=c+9.79
20.00-9.79=c
(so if u subtract the amount of money pablo has to pay from the money he has will be the change he will get)
10.21=c

Jaylin's test grades in History class are: 92, 89, 85, 89, and 90. The semester final will count as IWULUI.
Jaylin needs to earn a grade of 90 or higher for the semester. What is the minimum score Jaylin can earn
on the final exam and receive a final grade of 90 for the semester?
Answer:
95
Step-by-step explanation:
Find the mean by adding all of it and dividing it by the total of numbers,so I did that and put an extra 95 and the mean was 90,Please give me brainliest if it help
Jaylin's test grades in History class → 92, 89, 85, 89 and 90
Let the marks achieved in the final semester = x
Total marks achieved = 92 + 89 + 85 + 89 + 92 + x
= 447 + x
Minimum or the average marks required in 6 semester = 90
Total marks required in 6 semesters = 90×6
= 540
447 + x = 540
x = 540 - 447
x = 93
Therefore, Jaylin should achieve minimum 93 marks in the last semester.

The larger of two complementary angles is 6 degrees less than 7 times the smaller. Find the measure of the smaller angle.
Answer:
Step-by-step explanation:
The sum of two complementary angles is 90.
Let the two angles be x and y.
If x and y are complementary, then x+y = 90
If the larger of two complementary angles is 6 degrees less than 7 times the smaller then y = 7x-6 (y is the larger and x is the smaller)
Substituting y = 7x-6 into the formula above;
x+7x-6 = 90
8x - 6 = 90
8x = 90+6
8x = 96
x = 96/8
x = 12°
Hence the measure of the smaller angle is 12°
