Answer:
y=-8/3x-58/3
Step-by-step explanation:
8x-3y=-4 is y=8/3x+4/3
Make x negative so it is perpendicular
The plug (-8,2) so
2=8/3(-8)+b
Then
2=-64/3+b
-58/3=b plug b in to the equation so

Answer:
3x + 8y = - 8
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
8x - 3y = - 4 ( subtract 8x from both sides )
- 3y = - 8x - 4 ( divide through by - 3 )
y = [tex]\frac{8}{3}[/tex] x + [tex]\frac{4}{3}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{8}{3}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{8}{3} }[/tex] = - [tex]\frac{3}{8}[/tex] , then
y = - [tex]\frac{3}{8}[/tex] x + c ← is the partial equation of the perpendicular line
to find c substitute (- 8, 2 ) into the partial equation
2 = 3 + c ⇒ c = 2 - 3 = - 1
y = - [tex]\frac{3}{8}[/tex] x - 1 ← equation of perpendicular line in slope- intercept form
multiply through by 8 to clear the fraction
8y = - 3x - 8 ( add 3x to both sides )
3x + 8y = - 8 ← equation of perpendicular line in standard form

Which is the better buy? 2-cup carton of milk for $0.56 2-quart carton of milk for $3.76
Given:
2-cup carton of milk = $0.56
2-quart carton of milk for $3.76
To find which of them is a better buy, let's calculate the price of each cup for both.
i) 2-cup carton of milk = $0.56
1 cup =
[tex]\frac{0.56}{2}\text{ = }0.28[/tex]Here, 1 cup carton of milk is $0.28
ii) 2-quart carton of milk = $3.76
Given that 1 quart = 4 cups
2 quart = 4 * 2 = 8 cups
Thus
1 cup =
[tex]\frac{3.76}{8}\text{ = }0.47[/tex]Here, a cup carton of milk is $0.47
$0.28 is less than $0.47, therefore the better buy would be 2-cup carton of milk for $0.56.
Therefore, the best buy would be 2-cup carton of milk for $0.56, because it is cheaper.
ANSWER:
2-cup carton of milk for $0.56

Step-by-step explanation:
Eloise practiced piano for 2/5 of an hour. Sarah practiced piano for 3/4 of an hour.
How much longer did Sarah practice than Eloise?
Enter your answer as a fraction in simplest form by filling in the boxes.
Sarah practiced 7/20 of an hour more than Eloise
Given
Eloise did practice 2/5 of an hour
Sarah practiced for 3/4 of an hour
total time spent by Eloise = 2/5 x 60
= 24 minutes
Total time spent by Sarah = 3/4 x 60
= 45 minutes
Hence Sarah spent 45-21 minutes more.
Sarah spent 21 minutes more than Eloise
Converting into fractions 21 minutes will be,
a/b x 60 =21

You and your friends plan to attend the county fair this weekend. The admission to the fair is $5 and the cost per ride is 50 cents. If your parents gave you $20, write and solve a linear equation to find how many rides you can go on.
The linear equation to find how many rides you can go on is 5 + 0.5x = 20 and there'll be 30 rides.
What is an equation?A mathematical equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.
The linear equation will be:
Let the number of rides be x.
This will be:
5 + (0.5 × x) = 20
5 + 0.5x = 20
Collect like terms
0.5x = 20 - 5
0.5x = 15

There will be 30 rides, and the linear equation to determine the total number of rides is 5 + 0.5n = 20.
What are the equations?Mathematical statements which have at least two terms with equal quantities or variables are called equations.
Let n be the total number of rides.
The fair's entrance fee is $5, and each ride costs 50 cents, and parents gave $20 which is given in the question.
According to the given situation, the required equation as
⇒ 5 + 0.5 × n = 20
⇒ 5 + 0.5n = 20
⇒ 0.5n = 20 - 5
⇒ 0.5x = 15
Divide by 0.5 into both sides of the equation,
⇒ n = 15 / 0.5
⇒ n = 30
Therefore, the total number of rides will be 30.

Not sure how to find the area of this shape. Please help asap
Answer:
6.75m^2
Step-by-step explanation:
The shape is made up of a trapezoid on top and a rectangle on the bottom.
The rectangle's area is easier, so first:
Area_rectangle
= length × width
= 2.5 × .5
= 1.25 m^2
For area of a trapezoid, you need three measures: both bases and the height.
One base is 3m. The other base is the top side of the rectangle, so it is 2.5m.
The height is
2.5 - .5
because the height of the trapezoid is not including the rectangle, so take away .5
Trapezoid's height is 2.5 - .5 is 2.
Area_trapezoid
= 1/2 (base+base)height
= 1/2 (3+2.5)2
=5.5
Area_total
= Trapezoid+rectangle
= 5.5 + 1.25
=6.75m^2
The total area is 6.75square meters.
Answer:
Area = 6.75 meter square.

The transformation of the graph y = (x - 2)² to the graph of y=x²-3 is 2 units left and 3 units down therefore, option (B) is correct.
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
As per the given graph y = (x - 2)²
A function will shift a unit left for x → x + a and b units down if y → y - b.
Replace x → x + 2 and y → y - 3
y = (x + 2 - 2)² - 3
y = x² - 3

You are creating identical candy bags using 36 chocolate bars and 81 caramel bars. what is the greatest number of bags you can fill using all the candy?
The greatest number of bags that can be filled using all the candy is 9.
The greatest number of bags that can be filled using all the candy can be determined by calculating the greatest common factor (GCF).
The greatest common factor of two or more numbers is a term used in mathematics that can be described as the greatest number among all the common factors of these numbers. If x and y are two numbers, GCF is the largest number that divides both x and y without leaving any remainder.
As there are 36 chocolate bars and 81 caramel bars, therefore we determine the GCF of 36 and 81;
The common factors of 36 and 81 are found to be: 1, 3 and 9

a) Which factory used more oil last year? By how much'
Oil
Salt
b) what is the total amount of salt use by both factories?
c) what is the total weight of all of the ingredients in Factory A?
Factory A uses more oil by 2.05×10⁵ lbs, total salt used is 4.805×10⁵ lbs and total ingredients used in factory A are 57.18×10⁵ lbs.
a) The oil used by Factory A = 5.61×10⁵ lbs
The oil used by Factory B = 3,56,000 lbs
The oil used by Factory B = 3.56×10⁵ lbs
Comparing the coefficient. Since 5.61 is greater than 3.56, the factory A used more oil. Difference in amount = 5.61×10⁵ - 3.56×10⁵
Difference in amount = 2.05×10⁵ lbs
b) Salt used by Factory A = 2.87×10⁵ lbs
Salt used by Factory B = 193,500 lbs
Salt used by Factory B = 1.935×10⁵ lbs
Total salt used by both the factories = 2.87×10⁵ + 1.935×10⁵ lbs
Total salt used by both the factories = 4.805×10⁵ lbs
c) Potato used by Factory A = 4.87×10⁶ lbs
Potato used by Factory A = 48.7×10⁵lbs
Oil used by Factory A = 5.61×10⁵ lbs
Salt used by Factory A = 2.87×10⁵ lbs
Total ingredients used in Factory A = 48.7×10⁵ + 5.61×10⁵ + 2.87×10⁵ lbs
Total ingredients used in Factory A = 57.18×10⁵ lbs
2.05×10⁵ lbs more oil is used by Factory A, 4.805×10⁵ lbs is the total amount of salt used and 57.18×10⁵ lbs ingredients are used in factory A.
