solve for a. 1/3(21-3a)=6-a
Answer:
no solution
Step-by-step explanation:
Given
[tex]\frac{1}{3}[/tex] (21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )
21 - 3a = 18 - 3a ( subtract 21 from both sides )
- 3a = - 3 - 3a ( add 3a to both sides )
0 = - 3 ← not possible
This indicates the equation has no solution

Suppose y varies directly with x. If y = 6 when x = 18, find the value of y when
x= 8.
Answer:
y = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition
y = 6 when x = 18 , then
6 = 18k ( divide both sides by 18 )
k = [tex]\frac{6}{18}[/tex] = [tex]\frac{1}{3}[/tex]
y = [tex]\frac{1}{3}[/tex] x ← equation of variation
When x = 8, then
y = [tex]\frac{1}{3}[/tex] × 8 = [tex]\frac{8}{3}[/tex]

Triangle XYZ is a right triangle with the right angle at vertex Y.
Angle X must be
.
Angle Z must be
.
The sum of angles X and Z must be
90°.
The sum of angles X and Z is 90°.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Triangle XYZ.
∠Y = 90°
Now,
The sum of the three angles must be 180°.
So,
∠X + ∠Y + ∠Z = 180
∠X + ∠Z = 180 - 90
∠X + ∠Z = 90
Thus,
∠X + ∠Z = 90

What is the equation of the least-squares regression line for the data set?
A) y=−1.988x+43.293
B)y=−0.879x+43.293
C)y=1.988x−43.293
D)y=−0.879x−43.293
Answer:
The answer is option A y = −1.988x + 43.293
Step-by-step explanation:
I just took the test
The equation of the least squares regression line for the data set will be;
y = -1.988x + 43.293
Option A is true.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The table of data set is shown in figure.
Now, Let hours represent by x.
And, Tickets sold represent by y.
So, By the equation;
y = -1.988x + 43.293
Substitute x = 11;
y = -1.988 × 11 + 43.293
y = - 21.868 + 43.293
y = 21.62
y = 22
And, For x = 9;
y = -1.988 × 9 + 43.293
y = -17.892 + 43.293
y = 25.4
y = 24
Thus, Equation y = -1.988x + 43.293 shows the least-squares regression line for the data set.
So, The equation of the least squares regression line for the data set will be;
y = -1.988x + 43.293

Eduardo has to make a 10 minute video of his test corrections for his Algebra 2 teacher in order to be eligible to retest. His teacher said he must stay within three minutes of the 10 minute requirement. Write an absolute value inequality that represents video lengths that meet the requirement. No spaces. On your keyboard,
Answer:
7 ≤ v ≤ 13
Step-by-step explanation:
Length of video required must be within 10 minutes
Submitted length of video must be with 3 minutes of the 10 minutes video
To create an absolute value inequality :
Let v = the range of value for which the required video will be :
|v - 10| = ±3
Lower boundary :
|v - 10| = - 3
v = - 3 + 10
v = 7
Upper boundary :
|v - 10| = 3
v = 3 + 10
v = 13
Hence,
7 ≤ v ≤ 13
