Devon wants to write an equation for a line that passes
through 2 of the data points he has collected. The points
are (8, 5) and (-12, -9). He writes the equation
7x-10y=3. Is this a
reasoning.
good model? Explain your reasoning.
Answer:
7x-10y=6
Step-by-step explanation:
Firstly, supervise 7x-10y=3 using the coordinates of one from the known points
7*8-10*5=3
6=3 It is not correct, so the equation is uncorect
Find the correct equation
The common equation is y=mx+b
5=8m+b
-9=-12m+b
Both equations are simultaneous.
-9-5= -12m+b- (8m+b)
-14=-20m
m=0.7
b=5-5.6=-0.6
y=0.7x-0.6
0.7x-y=0.6
7x-10y=6- the correct answer

11 Alicia buys a car that costs $26610, and she makes a $3140 down payment on it. How much
does she still owe on the car? Give units.
Answer:
$23,470
Step-by-step explanation:
A down payment is how much you pay upfront for a car. So, how much she still owes will be the difference between the total cost and the down payment. Therefore, subtract $3,140 from $26,610; 26610-3140=23470. Then, since you are talking about money the units are dollars, $.

X/2-7=9
Show your work in details if you can, I have a hard time understanding this.
Answer:
Step-by-step explanation:
x/2 - 7 = 9 Add 7 to both sides
+7 7
x/2 = 16 Multiply both sides by 2
2*x/2 = 16*2
x = 32
You are at about the second stage of solving equations. So far what you should know is that you should add or subtract before doing multiplication or division.
Take a much simpler question
x - 8 = 10 What do you do here? You can't multiply or divide. So add
+8 8
x = 18
Now try what you have
2x - 5 = 11 Add before multiplication or division
5 5
2x = 16 Divide by 2
2x/2 = 16/2
x = 8

Margie had 4 2/5 pans of lasagna. After a party she has 1 1/2 pans left. How much lasagna was eaten at the party
Answer:
2 9/10 pans
Step-by-step explanation:
4 2/5-1 1/2=2 9/10 pans
2 and 9/10 pans of lasagna were eaten at the party.
To find out how much lasagna was eaten at the party, you need to calculate the difference between the initial amount of lasagna Margie had and the amount she has left after the party.
Initial amount of lasagna = 4 2/5 pans
Amount left after the party = 1 1/2 pans
First, we need to convert both fractions to a common denominator. The common denominator of 5 and 2 is 10.
Initial amount of lasagna = 4 x 10/10 + 2/5 x 10/10
= 40/10 + 4/10
= 44/10 pans
Amount left after the party = 1 x 10/10 + 1/2 x 10/10
= 10/10 + 5/10
= 15/10 pans
Now, subtract the amount left after the party from the initial amount to find out how much lasagna was eaten:
Amount eaten = Initial amount - Amount left
Amount eaten = 44/10 - 15/10 = 29/10 pans
You can simplify the fraction further:
Amount eaten = 2 + 9/10 pans
So, 2 and 9/10 pans of lasagna were eaten at the party.

Step-by-step explanation:
15) A small rectangular block of land has a perimeter of 100 m and an area of 225 m². Find the dimensions of the block of land.
Answer:
45 and 5 are the dimensions of the block of land.
Step-by-step explanation:
2(x + y) = 100, x + y = 100/2, y = (50 - x)
xy = 225
x (50 — x) = 225
0 = x^2 — 50x + 225
0 = (x — 45) (x -5)
45 and 5 are the roots of the above polynomial, thus they are the sides or dimensions of the block of land.

-√100/5 = ? Simply it please with full explanation. Thanks
Answer:
-2√5
Step-by-step explanation:
First simplify what's inside the radical: 100/5=20
Now we have -√20
The square root of 20 is 2√5 (because 5*4=20 and the square root of 4 is 2)
Because there is a negative the answer has to be -2√5

what is the unit rate of 1/7 and 1/21 ? this is very confusing?
Answer:
the unit rate of 1/7 is itself (1/7), and for 1/21 is 1/21.
Step-by-step explanation:
this is because these rates/ratios are unit fractions. so if the numerater is 1, theres nothing you can do to simplify it.
you can check with the ceaser method as well, but you're still going to find the same solution.

A pole that is 2.8 m tall casts a shadow that is 1.46 m long. At the same time, a nearby building casts a shadow that is 50.25 m long. How tall is the building?
Round your answer to the nearest meter.
Answer:
96 m
Step-by-step explanation:
Create a proportion where x is the height of the building:
[tex]\frac{2.8}{1.46}[/tex] = [tex]\frac{x}{50.25\\}[/tex]
Cross multiply and solve for x:
1.46x = 140.7
x = 96
So, the height of the building is approximately 96 m tall

Given the form of the equation 3x + 2y = 3 and x – 3y = -10. Then determine the result of 3x - y !
Answer:
-6
Explanation:
x= -1 and y=3
3x- y
=> 3(-1)-3 = -3-3= -6
Answer:
3x – y = -6
Step-by-step explanation:
To solve on the problem above, you can do it by substitution and elimination of the two equations.
3x + 2y = 3
➡️ 3x + 2.3 = 3
➡️ 3x + 6 = 3
➡️ 3x = -3
➡️ x = -1
➡️ 3x – y = 3(-1) – 3
➡️ = -3 – 3 = -6 ✅
