What is the solution to the system of equations?
2x – 3y = -1
y – x = -1
(a) Use the substitution method to find the solution.
(b) What do you know about the two lines in this system of equations (Hint: Do they intersect? Are they
parallel? Are they the same line?)
Siplified 1.6y
-3
y=x + 5
A ( To check a system of equations by substitution, you plug your values for x and y into the original equations. If both simplified expressions are true then your answer is correct.
For example: To check if
(
2
,
−
3
)
was the correct solution for the system of equation:
y
=
−
x
−
5
,
substitute 2 for x and -3 for y into each equation
They intersect and the lines are the same as parallel. They share the same line as going x to y.

Answer: 100
Hi!
ok so the Pythagorean theorem is
[tex]c=\sqrt{x} a^2+b^2=\sqrt{x} 8^2+6^2=10[/tex]
so the other side is 10.
the square 8 is 8*8
and square 6 is 6*6
so the other square is 10*10=100.
so the area of the blank square is 100.

A sphere has a volume of 1,436 in3. What is its radius?
Answer:
7
Step-by-step explanation:
So first you would have to know the formula for the volume of a sphere to solve for the radius. The formula is:
V=4 /3πr3
so now we plug in the variables
1,436=4/3πr3
divide by pi
457.09=4/3r3
divide by 4/3 (multiply by the reciprocal which is 3/4)
342.82=r3
Take the third root to get r by itself
r=6.998 or 7 if you will.
A 15-pound bag of dog food at Wagging Tails Pet Store costs $9.75. What is the cost per pound for the dog food?

Is (–3, –10) a solution to this system of inequalities? y ≥ 7x − 2 y < 4x + 7
Answer:
No, it is not a solution
Step-by-step explanation:
Given the inequality y ≥ 7x − 2 and y < 4x + 7, they can be combined and written as;
7x-2≤y<4x+7
Equate both values of y, the point of intersection occurs when;
7x-2 = 4x+ 7
7x - 4x = 7 + 2
3x = 9
x = 9/3
x = 3
Substitute x = 3 into y = 7x - 2
y = 7(3) - 2
y = 21 - 2
y = 19
Hence the possible solution will be at (3, 19). Hence the solution (-3, -10) is incorrect

The table shows the results of a survey of 150 students. Use the table to find the probability of a student participating in each sport.
1. Tennis
2. Football
3. Gymnastics
4. Volleyball
Can someone please help!
Answer:
See below
Step-by-step explanation:
Using the table of 150 students, we can configure probabilities.
18 students participate in tennis, so the probability of a student participating in tennis is 18/150, or 3/25 simplified.
45 students participate in football, so the probability of a student participating in football is 45/150, or 3/10 simplified.
12 students participate in gymnastics, so the probability of a student participating in gymnastics is 12/150, or 2/25 simplified.
9 students participate in volleyball, so the probability of a student participating in volleyball is 9/150, or 3/50 simplified.
Eliminate the y in the following system of equations. What is the result when you add the two equations?
3x - 2y = 8
x + y = 6
Answer:
X=4
Step-by-step explanation:
3x-2y=8
x+y=6
multiply second equation by 2 so you can eliminate y
2(x+y)=2(6)
2x+2y=12
now add two equations together
first equation: 3x-2y=8
modified second equation 2x+2y=12
added together eliminates y. 5x+0=20
X=4

Does anybody know how to find the distance between 2 things using the pythagorean theorem?
Answer:
Yes
Step-by-step explanation:
The two objects are plotted at different points in graph and one gets the difference of points y coordinates (change in y) and change in x too.
Then one can look for distance as hypotenous and change in y as height and change in x as the base of our imaginery triangle.
Therefore, from Pythagoras Theoreom:
hyptenous² = height² + base²
Distance² = change in y² + change in x²
Distance = √change in y² + change in x²
Find the angle measures
Answer:
m<1 = 140º
m<2 = 40º
Step-by-step explanation:
5x + x + 12 = 180
6x + 12 = 180
6x = 180 - 12
6x = 168
x = 28
<1 = 28 x 5 = 140º
<2 = 28 + 12 = 40º

A new car sells for $34,500. If the car depreciates at a rate of seven and a half percent each year, how much will the car be worth in five years?
Answer:
$23356.5
Step-by-step explanation:
Given data
Cost = $34,500
rate= 7.5%
Time= 5 years
The expression for the depreciation is
A= P(1-r)^t
substitute
A= 34500(1-0.075)^5
A= 34500(0.925)^5
A= 34500*0.677
A=$23356.5
Hence the worth will be $23356.5

0.75(4x + 2) = 5 - (x + 1.5)
X =
Answer:
The answer is x=1/2 or x=0.5
Answer:
x = 0.5
Step-by-step explanation:
0.75(4x + 2) = 5 - (x + 1.5)
3x + 1.5 = 5 - x - 1.5
3x + 1.5 = -x + 3.5
3x + x = 3.5 - 1.5
4x = 2
x = 0.5

Maya is finding the area of the shaded triangle below.
A triangle has a base of 73 meters and a height of 10 meters.
If she considers 10 m to be the height of the triangle, what should she use as the triangle’s base?
22 m
25 m
52 m
73 m
Answer:
d) 73 m
Step-by-step explanation:
From the Question, we are told that:
Maya is finding the area of the shaded triangle below.
A triangle has a base of 73 meters and a height of 10 meters.
If she considers 10 m to be the height of the triangle, what should she use as the triangle’s base?
The area of a triangle = 1/2 × Base × Height
We are already told the base of the triangle from the question and this is 73 m
Option D, 73 m is the correct answer

Which factors of -24 will give you a sum of -5?
A negative number always factors as a positive times a negative.
I would reccomend doing it systematically, like I have done below.
When ding it this way, you will see that -8 and +3 satisfy both requirements.
