The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Answers
Answer: y=x-20
Step-by-step explanation:
(90,70) will be x1,y2. (30,10) will be x1,y1. Put these values into the slope formula, which is y2-y1/x2-x1. 70-10/90-30. 60/60=1. The slope is 1. Now to find the slope-intercept equation, use point slope form which is y-y1=m(x-x1). y-10=1(x-30). Distribute the 1 to the terms in the parenthesis. y-10=x-30. Add 10 to both sides to eliminate 10. y-10+10=x-30+10. y=x-20.

$13.5
Step-by-step explanation:
$4x+ 12 \(\leq\) $66.
First, subtract 12 from both sides.
The 12 cancels out 12, so we are at: $4x \(\leq\) $66.
Divide.
66 / 4 = 13.5.
Answer: 4. First, a solid circle should be drawn on 13.5 since it is a value you get when you simplify the inequality and then you should draw a thick straight line to the greater side which is the right side of the number line
Step-by-step explanation:
since you have already found the answers for 1,2 and 3 you are said to draw and show the inequality on a number line but first, you should make 'x' the subject of the inequality you have formed.
How 'x' is made the subject:
4x + 12 \(\leq\) 66
4x \(\leq\) 66-12
\(\frac{4x}{4} \leq \frac{54}{4}\)
x \(\leq\) 13.5 ← *so this is the one you should graph on your number line*
(since you can't draw it in the question form given to you I'll show you how it has to be drawn and I'll explain)
4. First a solid circle should be drawn on 13.5 since it is a value you get when you simplify the inequality and then you should draw a thick straight line along the number line to the greater side which is the right side of the number line

Trying to complete ASAP. You are throwing a party and have a 1-liter jar of sauce for dipping mozzarella sticks. Part A: Determine how many ounces are in 1 liter. Show every step of your work. (10 points) Part B: You need to use 2-ounce containers for your guests. How many of these containers can you fill with sauce? Show every step of your work. (2 points)
Answers
Answer:A. 33.814 ounces B. 17 containers.
Step-by-step explanation:
Since there is only 33.814 USA fluid ounces (fl. oz) A is answered.
\(\frac{33.814}{1}\) = 33.814
A. 33.814 ounces
Now that you need 2-ounce containters to fill with the 33.814 ounces (at this point you cant round to 34 ounces) how many cups do you need?
33.814/2 = 16.907 ounces (basicly 17 cups for the guests)
B. 17 containers.
Part A : The number of ounces in 1 liter is 33.814 ounces.
Part B : The number of containers that can fit the sauce is 17.
What is Unit Conversion?Unit conversion is defined as expressing the same quantity by different measurement units.
For example, a distance of 20 meter can be also expressed as 2000 cm. The distance is same.
Given that,
Amount of sauce for dipping mozzarella sticks = 1 liter
Part A :
We have the unit conversion,
1 liter = 33.814 ounces
Part B :
Measurement of containers = 2 ounces
Total amount of sauce = 33.814 ounces
We have to divide the total amount of sauce in to 2 ounce containers.
Number of containers formed = 33.814 / 2 = 16.907 ≈ 17
Hence there will be 17 containers of sauce.

c) Nonproportional because the bottles have different unit rates.

When a spaceship full of scientists landed on Planet Q, they found that 3/8 of the 160 aliens had 3 eyes. The rest of the aliens had 5 eyes. How many eyes total do the 160 aliens have?
Answers
Answer:
680 eyes.
Step-by-step explanation:
160 · 3/8 = 60
60 aliens have 3 eyes. That means the other 100 aliens have 5 eyes.
60 · 3 = 180
100 · 5 = 500
500 + 180 = 680
Therefore, the 160 aliens have a total of 680 eyes.
