What would the value of a equal so the linear function ay - 2x = 9 is parallel to a line with a slope of 2/3?
Answer:
y = [tex]\frac{2}{3} x + 9[/tex]
Step-by-step explanation:
I. If y = mx + b
when y is output, x is input , m is slope and b is addition
so y - 2x = 9
y = 9 + 2x
y = 2x + 9
Replace 2 with [tex]\frac{2}{3}[/tex]
y = [tex]\frac{2}{3} x[/tex] + 9
Answer:
a is 3
Step-by-step explanation:
[tex]ay - 2x = 9 \\ ay = 2x + 9 \\ y = \frac{2}{a} x + \frac{9}{a} [/tex]
General equation:
[tex]{ \bf{y = mx + c}}[/tex]
m is slope; m = ⅔
by comparison:
[tex] \frac{2}{3} = \frac{2}{a} \\ \\ 2a = 6 \\ a = 3[/tex]

A company has a policy of retiring company cars; this policy looks at number of miles driven, purpose of trips,
style of car and other features. The distribution of the number of months in service for the fleet of cars is
bell-shaped and has a mean of 63 months and a standard deviation of 11 months. Using the 68-95-99.7 rule,
what is the approximate percentage of cars that remain in service between 30 and 52 months?
Do not enter the percent symbol.
ans =
%
This value is approximate.
====================================================
Explanation:
mu = 63 = population meansigma = 11 = population standard deviationLet's convert x = 30 to its corresponding z score
z = (x-mu)/sigma
z = (30-63)/11
z = -33/11
z = -3
This score is 3 standard deviations below the mean.
Repeat for x = 52
z = (x-mu)/sigma
z = (52-63)/11
z = -11/11
z = -1
This score is 1 standard deviation below the mean.
The task of finding P(30 < x < 52) is the same as P(-3 < z < -1)
We converted to z scores so we could use the Empirical Rule.
Refer to the chart below. We'll be focusing on the left green portion that is between z = -3 and z = -2 and the left blue portion which is between z = -2 and z = -1.
Those two approximate areas add to: (2.35%) + (13.5%) = 15.85%
What is the equation of the line that passes through the point ( − 4 , 8 )and has a slope of − 1/4
Answer:
y = -1/4x + 7
Step-by-step explanation:
Plug in the point and slope into y = mx + b, and solve for b:
y = mx + b
8 = -1/4(-4) + b
8 = 1 + b
7 = b
Plug in the slope and b into y = mx + b:
y = mx + b
y = -1/4x + 7
So, the equation of the line is y = -1/4x + 7
Find the midpoint of the line segment with end coordinates of: ( 2 , 0 ) and ( 8 , 8 )
Answer:
mid point is (1, 8)
Step-by-step explanation:
[tex]{ \bf{midpoint = ( \frac{x_{1} + x _{2} }{2} , \: \frac{y _{1} + y _{2} }{2} ) }}[/tex]

Simplify: a(3+5a)-4(a2+5)
Answer:
[tex]\displaystyle a( 3 + 5a) - 4(a^2 +5) = a^2 + 3a - 20[/tex]
Step-by-step explanation:
We want to simplify the expression:
[tex]a( 3 + 5a) - 4(a^2 +5)[/tex]
Distribute:
[tex]\displaystyle = (3a + 5a^2) + ( -4a^2 - 20)[/tex]
Rearrange:
[tex]\displaystyle = (5a^2 - 4a^2) + (3a) + (-20)[/tex]
Combine like terms:
[tex]\displaystyle = a^2 + 3a -20[/tex]
In conclusion:
[tex]\displaystyle a( 3 + 5a) - 4(a^2 +5) = a^2 + 3a - 20[/tex]

Simplify an expression for the perimeter of the rectangle.
W = 24.6x - 10.4
L = 7x + 3.1
The expression for the perimeter of the rectangle is 63.2x - 14.6.
Given that,
Width = W = 24.6x - 10.4Length = L = 7x + 3.1We Know that
Perimeter of the rectangle is
[tex]= 2(l+w)\\\\= 2 (7x + 3.1 + 24.6x - 10.4)\\\\= 2(31.6x - 7.3)[/tex]
= 63.2x - 14.6
Here the above formula should be applied for measuring the perimeter of the rectangle.
Therefore we can conclude that The expression for the perimeter of the rectangle is 63.2x - 14.6.

y+5=3/2(x-7) write in y=mx+b form
Answer:
[tex]y=\displaystyle \frac{3}{2}x-\frac{31}{2}[/tex]
Step-by-step explanation:
Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
Notice how y is isolated in slope-intercept form.
[tex]y+5=\displaystyle \frac{3}{2} (x-7)[/tex]
To change this into slope-intercept form, isolate y.
Use the distributive property on the parentheses:
[tex]y+5=\displaystyle \frac{3}{2}x-\frac{21}{2}[/tex]
Subtract 5 from both sides:
[tex]y=\displaystyle \frac{3}{2}x-\frac{21}{2}-5\\\\y=\displaystyle \frac{3}{2}x-\frac{31}{2}[/tex]

Does eating a mint affect a person's taste buds? To
answer this question, students were randomly placed
into two groups. One group had to eat a mint, and the
other did not. Then all the students were given a cup
that had one of two brands of ice tea. Students were
asked to guess which brand of ice tea they had. The
results are displayed below.
There is an association because the distribution of
correct guesses differs among the mint groups.
