Answer:
x=6, y = -9
Step-by-step explanation:
6x + 2y = 18
-4x - 2y = -6
Add the two equations together to eliminate y
6x + 2y = 18
-4x - 2y = -6
------------------------
2x +0y = 12
Divide by 2
2x/2 = 12/2
x = 6
Then find y
6x+2y = 18
6*6 +2y = 18
36+2y = 18
Subtract 36 from each side
36+2y-36 = 18-6
2y = -18
Divide by 2
2y/2 = -18/2
y = -9

Answer:
s = 120
r = 33
t = 33
Step-by-step explanation:
You are solving for the variables r & t & s. Note that it is given that the two parallelograms are congruent with each other.
Make sure that they are facing the same way. Note that DC ≅ GH, AD ≅HE, FE ≅ AB
Solve:
DC ≅ GH; 70 = s - 50
Isolate the variable, note the equal sign, what you do to one side, you do to the other. Add 50 to both sides;
70 (+50) = s - 50 (+50)
s = 70 + 50
s = 120
Solve:
AD ≅ HE
2r = 66
Isolate the variable, divide 2 from both sides:
(2r)/2 = (66)/2
r = 66/2
r = 33
Solve:
FE ≅ AB
t + 50 = 83
Isolate the variable, subtract 50 from both sides:
t + 50 (-50) = 83 (-50)
t = 83 - 50
t = 33
If EF = 6 and EG = 23, find the value of FG.
Answer:
FG=138
Step-by-step explanation:
Since 23 is a prime number, the only factors of it are 1 and 23.
Which means E is either 1 or 23.
Since 23 is not a factor of 6, E=1. Therefore, G= 23. And, F=6.
So, FG=23*6, which means FG=138.

Step-by-step explanation:
A rectangular parking lot has a length that is 10 yards greater than the width. The area of the parking lot is 600 square yards. Find the length and the width
Step-by-step explanation:
Let x be the width of the parking lot. Then (x + 10) is the length of the parking lot.
x(x + 10) = 600
x^2 + 10x = 600
x^2 + 10x - 600 = 0
(x+30)(x-20) = 0
x = 20 or x = -30 (rejected as x must be positive)
Hence the length is 30 yards and the width is 20 yards.
the price of a shirt is increased by 10%. later the price is reduced in a sale by 10%, is the sale price more, less or the same as it was at the start? give reasons for your answer
Answer:
less
Step-by-step explanation:
We assume price of a shirt is $100.
Initially price is increased by 10%: 100+10=110
Then it is reduced by 10%: 110-11=99
Now price of a shirt is $99.
Answer is price of a shirt is less than it was at the start.

Answer: Try 6
Step-by-step explanation:
The value of segment DF will be 8 units.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the points C, D, E and F all lie on the same line segment, in that order, such that the ratio of CD: DE: EF is equal to 3 : 2: 6. If CF = 11. The value of DF will be calculated as below:-
3x + 2x + 6x = 11
11x = 11
x =1
DF = 2x + 6x
DF = 2 + 6
DF = 8
Therefore, the value of segment DF will be 8 units.

Juvi is baking oatmeal raisin cookies and fudge brownies! To make 4 batches of brownies, Juvi needs 2/3 of a cup of sugar. She already has 1/2 of a cup of sugar in her cabinet and her sister Evi brings her 2/5 of a cup of sugar when she hears she needs more! Will Juvi have enough sugar to make 4 batches of brownies? If she does not have enough, how much more does she need? Explain below.**PLEAE HELP WILL MARK BRAINLIEST.
We can add the fractions together to compare with how much sugar she needs.
[tex]\frac{1}{2}+\frac{2}{5}=\frac{5}{10}+\frac{4}{5}=\frac{9}{10}[/tex]
So Juvi has [tex]\frac{9}{10}[/tex] cups of sugar.
She needs [tex]\frac{2}{3}[/tex] cups, so let's make the denominators the same and compare.
[tex]\frac{2}{3}=\frac{20}{30}[/tex]
[tex]\frac{9}{10}=\frac{27}{30}[/tex]
Since [tex]\frac{27}{30}[/tex] > [tex]\frac{20}{30}[/tex], she has enough sugar to make 4 batches of brownies.
Hope this helps.

If two functions have no solutions, what does that tell you about the two functions?
Answer: That the graphs of the functions never intersect with each other.
Step-by-step explanation:
i guess that this refers for a system of equations.
y = f(x)
y = g(x)
So to solve this, we usually would write:
f(x) = y = g(x)
If that has no solutions, it means that the graphs of f(x) and g(x) never cross eachother.

A burst of electromagnetic radiation has a frequency of 1 exahertz. One exahertz equals 10^12 megahertz. Each megahertz is equal to 10^6 hertz. What was the frequency of the burst of radiation in hertz? (^ indicates an exponent) *
Answer:
The frequency of the burst of electromagnetic radiation which equals 1 exahertz = 10¹⁸ hertz.
Step-by-step explanation:
Since the frequency of the burst of electromagnetic radiation is 1 exahertz, and 1 exahertz = 10¹² megahertz. So, the frequency of radiation is 10¹² megahertz. Also 1 megahertz = 10⁶ hertz. So, 10¹² megahertz = 10¹² × 1 megahertz = 10¹² × 10⁶ hertz = 10¹² ⁺ ⁶ hertz = 10¹⁸ hertz.
So the frequency of the burst of electromagnetic radiation which equals 1 exahertz = 10¹⁸ hertz.

The coordinates of the point (-8,0) after the 270° counterclockwise rotation of the points about the origin will be (0,-8).
What is geometric transformation?It is characterized as the modification of the geometric body's form and coordinates. As a two-dimensional transformation, it is also known as. Rotation, translation, reflection, and gliding translation are only a few of the geometric transformation's conceivable modifications to the geometry.
It is given that the coordinate is (-8,0) and the point is rotated by 270° counterclockwise about the origin
We have to find the coordinates after a rotation of 270° counterclockwise about the origin.
Plot the points and observe the coordinate in the graph for the given condition.
Thus, following a 270° counterclockwise rotation of the points around the origin, the coordinates of the point (-8, 0) will be (0,-8).

2 factory plants are making TV panels. Yesterday, Plant A produced 6000 fewer panels than Plant B did. Two percent of the panels from Plant A and 5% of the panels from Plant B we’re defective. How many panels did Plant B produce, if the two plants together produced 1140 defective panels
Answer:
Number panels Plant B produce = 18,000
Step-by-step explanation:
Given:
Plant produces defective panels = 1140
Plant B produce = 5%
Plant A produce = 2%
Find:
Number panels Plant B produce
Computation:
Assume
Number panels Plant B produce = x
Number panels Plant A produce = x - 6000
So
5%(x) + 2%(x-6000) = 1140
0.05x + 0.02x - 120 = 1140
0.07x = 1260
x = 18,000
Number panels Plant B produce = 18,000
The functions y=x2+cx2 are all solutions of equation: xy′+2y=4x2, (x>0). Find the constant c which produces a solution which also satisfies the initial condition y(10)=2.
Answer: c = -0.98
Step-by-step explanation: Differential equation of first order is an equation involving differentiable function and its derivative.
For the differential equation: [tex]xy' +2y=4x^{2}[/tex], it given a solution function:
[tex]y=x^{2}+cx^{2}[/tex]
Factorating the function: [tex]y=x^{2}(1+c)[/tex]
So, to determine constant c, use the initial condition:
When x = 10, y = 2:
[tex]2=10^{2}(1+c)[/tex]
[tex]1+c=\frac{2}{100}[/tex]
[tex]1+c=0.02[/tex]
c = -0.98
Constant c that satisfies the initial condition is c = -0.98
