у= - 3х - 3
у = х + 5
Answers
Answer:
(x,y)=(-2,3)
Step-by-step explanation:
Since both expressions -3x-3 and x+5 are equal to y, set them equal to eachother forming an equation in x
-3x-3=x+5
solve the equation for x
x= -2
substitute the given value of x into the equation y=x+5
y= -2 +5
solve the equation for y
y=3
the possible solution of the system is the ordered pair (x,y)
(x,y) = (-2,3
check if the given ordered pair is the solution of the system of equations
{3= -3x(-2) -3
{3= -2 +5
simplify the equalitites
{3=3
{3=3
since all the equalitites are true, the ordered pair is the solution of the system
(x,y)=(-2,3)

Hi this is kind of hard to explain so for the exponents I will write them like this 2/4 or 2/2 (please dont get confused.)
POWER . BASE . Exponent . Expanded Form Value
2/4 2 . 4 . 2x2x2x2 16
2/1 . 2 1 2 2
3/2 3 2 3x3 9
3/3 3 3 3x3x3 27
3/4 3 4 3x3x3x3 81
4/2 4 2 4x4 16
4/3 4 3 4x4x4 64
Can somebody please explain to me how to do this !!!?
Answers
Answer:
Slope is 4
Step-by-step explanation:
Take a y value (like 18) and subtract it with another y value (14). This will be 4. Now take a x value corrleating with your y value (like 4 since it correlates with 18) and subtract is with another x value correlating with your other y value (it'll be 3 because it's correlating with 14). The x will become 1. Now divide the y and x, so it will be 4 b/c it's 4 divided by 1.

But if you read the problems the two that are very similar are the same but one of the problems says clockwise and the other is counter-clockwise. And the one that is shorter than the other three problems is the reflection; dil 2, and the other is kinda obvious. I hope you understand!!!!!

Multiply 20 by 0.90 (that is 90%)
18 is the answer
Hope this helps :)
Answer:
18
Step-by-step explanation:
Hello there. This problem can be easily solved by setting up a ratio.
This would be as follows
[tex]\frac{90percent}{100}[/tex] x [tex]\frac{x}{20 }[/tex]
after solving for x we find that 90% of 20 should be 18.

The Mad Hat Company must ship two different-sized boxes: The small ones cost them 45 cents each and weigh 6 ounces, and the large ones weigh 25 ounces and cost $1.20 each. The total shipment this morning weighed 20 pounds 7 ounces and cost $18.45. How many packages of each size were shipped?
Answers
Given :
The Mad Hat Company must ship two different-sized boxes: The small ones cost them 45 cents each and weigh 6 ounces, and the large ones weigh 25 ounces and cost $1.20 each.
The total shipment this morning weighed 20 pounds 7 ounces and cost $18.45.
To Find :
How many packages of each size were shipped.
Solution :
We know, 1 pound = 16 ounces.
So, 20 pound = 20×16 = 320 ounces.
Let, number of large and small box are l and s.
So,
25l + 6s = 327 ...1)
0.45s + 1.20l = 18.45 ...2)
Solving both the equations, we get :
x = 9 and y = 17
Therefore, package smaller and big size are 17 and 9 respectively .
Hence, this is the required solution.

It is an isosceles triangle which has two angles of the same measurement, Pretty easy to figure out.
Answer:
x= 64 ansdy=52
Step-by-step explanation:
Since the 64 line is congruent to the "x" line, it must be 64. A triangle's angles equal 180 so 180-64-64= 2 giving you "y"

which triangle congruence criteria can always be used to prove two triangles congruent in a coordinate plane?
Answers
Answer:
The Side-Side-Side congruency criteria
Step-by-step explanation:
The Side-Side-Side (SSS) congruency criteria can always be used to prove two triangles are congruent in a coordinate plane
When two triangles are presented in the coordinate plane, the coordinates of the vertices of both triangle will be given by the coordinates of their points on the coordinate plane
The length of the sides of each triangle will be given by the distances, d₁, d₂, d₃, between the coordinates of their vertices as follows;
[tex]d = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
The two triangles are congruent when the length of the three sides d₁, d₂, and d₃ of one triangle ABC, are congruent to the three sides d'₁, d'₂, and d'₃ of the other triangle A'B'C'.
When an item is marked up by a certain percent and then marked down by the same percent, is the sale price equal to the price before the markup and markdown? Explain.
Answers
Answer:
Step-by-step explanation:
For these, you calculate the markup or markdown in absolute terms (you find by how much the quantity changed), and then you calculate the percent change relative to the original value. So they're really just another form of "increase - decrease" exercises. A computer software retailer used a markup rate of 40%.
A middle school took all of its 6th grade students on a field trip to see a play at a theater that has 2760 seats. The students filled 45% of the seats in the theater. How many 6th graders went on the trip?
Answers
Answer:
1242 6th graders went on the trip.
Step-by-step explanation:
From the information given, you know that the theater has 2760 seats and that the students filled 45% of the seats, so to find the quantity of 6th graders that went on the trip, you have to calculate 45% of 2760:
2760*45%=1242
According to this, the answer is that 1242 6th graders went on the trip.
