What is a and b pls answer ASAP I need it !!! Plsss
Answer:
The value of a = 5.
the value of b = 6.
Step-by-step explanation:
Given the points on the line
(6, 10)(a, 8)(4, b)(2, 2)Given that all of the points are on the same line and the line represents a linear function.
Thus, the slope between any two points must be the same.
First, determine the slope between (6, 10) and (2, 2)
(x₁, y₁) = (6, 10)
(x₂, y₂) = (2, 2)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [2 - 10] / [2 - 6]
= -8 / -4
= 2
Thus, the slope of the line = m = 2
Determine the value 'a'
(x₁, y₁) = (6, 10)
(x₂, y₂) = (a, 8)
Using the slope formula to determine the value of 'a'
Slope = [y₂ - y₁] / [x₂ - x₁]
As the slope between two points is 2.
now substitute slope = 2, (x₁, y₁) = (6, 10) and (x₂, y₂) = (a, 8) in the slope formula
Slope = [y₂ - y₁] / [x₂ - x₁]
2 = [8 - 10] / [a - 6]
2(a - 6) = 8 - 10
2a - 12 = -2
2a = -2 + 12
2a = 10
divide both sides by 2
a = 5
Therefore, the value of a = 5.
Determine the value 'b'
(x₁, y₁) = (2, 2)
(x₂, y₂) = (4, b)
Using the slope formula to determine the value of 'b'
Slope = [y₂ - y₁] / [x₂ - x₁]
As the slope between two points is 2.
now substitute slope = 2, (x₁, y₁) = (2, 2) and (x₂, y₂) = (4, b) in the slope formula
Slope = [y₂ - y₁] / [x₂ - x₁]
2 = [b - 2] / [4 - 2]
2(4 - 2) = b - 2
8 - 4 =b - 2
4 = b - 2
b = 6
Therefore, the value of b = 6

Question 1
Find the measure of each angle indicated.
Answer:
90
Step-by-step explanation:
Answer:
90
Step-by-step explanation:
x + 70 =120 {Exterior angle theorem}
x = 120 - 70
x = 50
y = x {Vertically opposite angles}
y = 50
z + 50 + 40 = 180 {Angle sum property}
z + 90 = 180
z = 180 - 90
z = 90
-(1)=-1
{True or False}

There are 18 girls in Mr. Brimley's math class. If 40% of the students are girls, what is the best estimation for the number of boys in the class?
Answer:
30
Step-by-step explanation:
This is an easy one.
So, we know that 40% of the class is girls. We would need to use the other 60% as 60% of the class is boys and we would need to divide.
18/0.6=30
Therefore your answer is 30.
Hope this helps.
Answer:
20
Step-by-step explanation:
It is 40 percent ( given)
18/2=9
9×5=40 (100%)
Girls- 18( given)
Boys- 40-18=22

Solve the inequality for x.
- 4x + 16 > -64
A)
X> 12
B)
X > 20
x < 12
D
x < 20
Answer:
D: x < 20
Step-by-step explanation:
-4x + 16 > -64
subtract 16 from both sides because you must isolate x.
-4x + 16 - 16 > -64 - 16
-4x > -80
Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...
-4x/ -4 < -80/ -4
x < 20
(negative divided by a negative will result in a POSITIVE.)
Hope this helped... I truly apologize if this is wrong..

Find the value of x 8.5,9,7.5,6,7,x ;the mean is 8
Answer:
x= 10
Step-by-step explanation:
Mean is the sum of all values divided their number
(8.5+ 9 + 7.5 + 6 + 7 +x) / 6 = 8
(8.5+ 9 + 7.5 + 6 + 7 +x) = 8*6 = 48
(8.5+ 9 + 7.5 + 6 + 7 +x) =48
(38 +x) = 48
x= 48-38 = 10

How do you solve 13 + 3 - 8x + 6 = 1 - 5x I dont get it
Answer:
x = 7
Step-by-step explanation:
How to solve your question
Your question is 13 + 3 − 8x + 6 = 1 − 5x
13 +3 - 8x + 6 = 1 - 5x
13 + 3 − 8x + 6 = 1 − 5x
Solve
Add the numbers
13 + 3 − 8x + 6 = 1 − 5x
22 − 8x = 1 − 5x
Rearrange terms
22 − 8x = 1 − 5x
−8x + 22 = 1 − 5x
Subtract 22 from both sides of the equation
−8x + 22 −22 = −5x + 1 − 22
Simplify
Subtract the numbers
−8x = -5x + 1 -22
-8x = -5x -21
Add 5x to both sides of the equation
-8x + 5x = -5x -21 + 5x
Simplify
Combine like terms
-3x = -21
Divide both sides of the equation by the same term
(-3x)/3 = (-21)/3
Simplify
Cancel terms that are in both the numerator and denominator
x = (-21)/(-3)
Divide the numbers
x = 7
Answer: x=7
