Using the substitution of (y=y) what is y= -3x+5 y= -2x+3 (pls help this is)
Answer:
x = 2 and y = -1
Step-by-step explanation:
y = -3x + 5
y = -2x + 3
-3x + 5 = -2x + 3
Add 2x to both sides;
-x + 5 = 3
Subtract 5 from both sides;
-x = -2
Divide both sides by -1
x = 2
Solve for y;
y = -3x + 5
y = -3(2) + 5
y = -6 + 5
y = -1

What is the value of the expression
-1s/20r if r= -1/4 and s= 4/5?
Simplify your answer.
Answer:
[tex]\frac{4}{25}[/tex]
Step-by-step explanation:
Given expression:
[tex]-\frac{1s }{20r}[/tex]
r = [tex]-\frac{1}{4}[/tex] , s = [tex]\frac{4}{5}[/tex]
Now;
[tex]-\frac{1s }{20r}[/tex] = [tex]-\frac{s}{20r}[/tex]
Insert the parameters:
= [tex]-\frac{\frac{4}{5} }{20 x (-\frac{1}{4} )}[/tex]
= - [tex]\frac{\frac{4}{5} }{-5}[/tex]
-x - = +
= [tex]\frac{4}{5}[/tex] x [tex]\frac{1}{5}[/tex]
= [tex]\frac{4}{25}[/tex]

Answer:The answer would be 20 books divide 15 \ 1.50 equals 10 then multiply 10 by 2
Step-by-step explanation:
The number of books sold by Holly and Ethan to get a profit of $30 will be 20.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Holly and Ethan decide to sell some of their books at a flea market. The booth rental costs $15, and they will sell each book for $1.50.
The number of books will be calculated as,
1.5x = 30
x = 30 / 1.5
x = 20
Therefore, the number of books sold by Holly and Ethan to get a profit of $30 will be 20.

What is the distance between the last water stop and the end of the race? Enter your answer in the box.
Answer:
The distance between the last water shop and the end of the race is 2.1 miles
Step-by-step explanation:
Keep on adding 2.75 until you get the number 11 or you can just multiply 2.75 by 4 and get 11. Subtract 11 from 13.1 and you will get 2.1 miles.

a The diagonals of a rectangle intersect at 76°
Find the angle that a diagonal makes with a longer side of the rectangle.
b The diagonals of a rectangle intersect at xº.
Find the angle that a diagonal makes with a longer side of the rectangle.
Explanation: A diagonal of a rectangle cuts the rectangle into 2 right triangles with sides equal to the sides of the rectangle and with a hypotenuse that is the diagonal. All you need to do is use the pythagorean theorem: where a and b are the sides of the rectangle and c is the length of the diagonal.
The angle that a diagonal makes with a longer side of the rectangle is 38°.
The angle that a diagonal makes with a longer side of the rectangle is (x/2)°.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
a)
The diagonals of a rectangle intersect at 76°.
This means,
From the figure Triangle AOB.
AOB + OAB + OBA = 180
(180 - 76) + x + x = 180
2x = 180 - 180 + 76
2x = 76
x = 38
This means,
The angle with the longer side of the rectangle is 38.
b)
Similarly,
The diagonals of a rectangle intersect at xº.
This means,
AOB + OAB + OBA = 180
(180 - x) + y + y = 180
2y = 180 - 180 + x
2y = x
y = x/2
This means,
The angle with the longer side of the rectangle is x/2.
Thus,
The angle with the longer side of the rectangle is 38°.
The angle with the longer side of the rectangle is (x/2)°.

а. У
b. m
C. X
d. b
Answer:
m
Step-by-step explanation:
m=slope
b=y intercept
The symbol m is represent the slop of the line. the correct option is b.
Given that:
Equation: y = mx + b
Since the linear equation show by the formula: y = mx + b
Where,
the letter m represents the slope of the line. The slope m determines the rate of change of the dependent variable y with respect to the independent variable x in a straight-line equation. It indicates how steep the line is and whether it rises or falls as the value of x changes.
Hence, m is the slop of the given equation y = mx + c. The correct option is b.

Answer:

Step-by-step explanation:
What is the equation of this line?
Answer:
y= -5/4x + 6
Step-by-step explanation:
y= mx + b
m= -5/4 (rise over run/slope)
b= 6 (y-intercept)
-I hope this helps have a great day!
Answer:
y = -5/4(x)+6
Step-by-step explanation:
to find the equation of this line, we must first find the slope
We can write the equation of this line y = mx + b where m is the slope and b is the y-intercept
m = (y2-y1)/(x2-x1)
m = (-4-6)/(8-0)
m = -10/8
m = -5/4
b is the y intercept which is at 6
So the equation of the line is y = -5/4(x)+6
Janine's family is designing a new garage. Use A l w to determine the area of the garage if the length l is 24 feet and the width w is 22 feet. Find the area A of the garage in square feet.
Given :
Length of garage, l = 24 feet.
Width of garage, w = 22 feet.
To Find :
Area of garage in square feet.
Solution :
We know, area of a rectangular shape is given by :
Area = l × w
Area = 24 × 22 feet²
Area = 528 feet²
Therefore, area of garage is 528 feet².
Hence, this is the required solution.
triangle A'B'C is created by dilating triangle ABC by a scale factor of 4. what is the length of AB? The length of A'B'
Answer:
The length of AB is 20 units
Step-by-step explanation:
The given parameters from the graph for coordinates A and B are;
The coordinates of the point A = (1, 4)
The coordinates of the point B = (4, 8)
The length of segment AB is given by the equation for finding the distance, d between two points given their coordinates as follows;
[tex]d = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Where;
(x₁, y₁) = (1, 4)
(x₂, y₂) = (4, 8)
Substituting gives;
[tex]d_{AB} = \sqrt{\left (8-4 \right )^{2}+\left (4-1 \right )^{2}} = \sqrt{25} = 5[/tex]
The length of [tex]\overline {AB}[/tex] = 5
Therefore, given that ΔA'B'C is created by dilating ΔABC by a scale factor of 4, the length of A'B' = 4 × The length of AB
Therefore, the length of [tex]\overline {A'B'}[/tex] = 4 × The length of [tex]\overline {AB}[/tex] = 4 × 5 = 20
The length of [tex]\overline {A'B'}[/tex] = 20 units.

Bill has two fat cats. He feeds each cat 150 grams of dry food each, twice a day. If he buys a 5 kilogram bag of dry food, about how many days will the bag last?
Answer: 4 days (I think)
Step-by-step explanation:
One cat = 150*2 = 300g
Two cats = 600g
600*2 = 1200 (this is the total amount of food they both eat in a day)
5kg = 5000g
1200g/5000g = 4.17
The bag will last 4 days.

In math formulas, A and a, always represent the same number.
Answer: False
Step-by-step explanation:
In math formulas, we want to use different symbols to represent different things.
While in linguistics, A and a represent the same thing, the symbols are different, then we can use them to represent different things.
For example, we can define a square of side length a.
And the area of that square will be equal to the square of its side length, we can represent the area with A, such that:
A = a^2.
Here A and a are different numbers (and also represent different measures, a is in units of length and A is in units of surface).
Then the statement is false.

what is the number that is the sum of 6 and product of 8.
Answer:
2 and 4
Step-by-step explanation:
To find the answer to "What two numbers have a product of 8 and a sum of 6?" we first state what we know. We are looking for x and y and we know that x • y = 8 and x + y = 6.
Before we keep going, it is important to know that x • y is the same as y • x and x + y is the same as y + x. The two variables are interchangeable. Which means that when we create one equation to solve the problem, we will have two answers.
To solve the problem, we take x + y = 6 and solve it for y to get y = 6 - x. Then, we replace y in x • y = 8 with 6 - x to get this:
x • (6 - x) = 8
Like we said above, the x and y are interchangeable, therefore the x in the equation above could also be y. The bottom line is that when we solved the equation we got two answers which are the two numbers that have a product of 8 and a sum of 6. The numbers are:
2

Answer: 2 and 4

-2(-9x+5)-4x=2(x-5)-4
Simplify your answer as much as possible
Answer:
−2(−9x+5)−4x=2(x−5)−4
Step 1: Simplify both sides of the equation.
−2(−9x+5)−4x=2(x−5)−4
(−2)(−9x)+(−2)(5)+−4x=(2)(x)+(2)(−5)+−4(Distribute)
18x+−10+−4x=2x+−10+−4
(18x+−4x)+(−10)=(2x)+(−10+−4)(Combine Like Terms)
14x+−10=2x+−14
14x−10=2x−14
Step 2: Subtract 2x from both sides.
14x−10−2x=2x−14−2x
12x−10=−14
Step 3: Add 10 to both sides.
12x−10+10=−14+10
12x=−4
Step 4: Divide both sides by 12.
12x
