Answer: x = 20*
Solve by elimination
6x+2y=42
8x-4y=36
I will mark as brainliest
Answer:
x=6, y=3
Step-by-step explanation:
6x +2y=42------(1)
8x-4y=36-------(2)
We can actually simplify it, this makes it easier to do and can avoid alot of careless mistakes
3x+y=21---(1)
2x-y=9----(2)
next, we can see that y can be eliminated
(1)+(2),
5x=21 +9
x = 30/5
x=6
substitute x=6 into (2),
2(6)-y=9
y=3
Lastly ,make a conclusion
Thus, x=6, y= 3
[tex] 6x + 2y = 42 \\ 8x - 4y = 36[/tex]
Simplify the first equation
[tex]y = 18 \\ 8x - 4y = 36[/tex]
Multiply both sides of second equation by 1/4
[tex]y = 18 \\ 2x - y = 9[/tex]
Sum the equations vertically to eliminate at least one variable
[tex]x = \frac{27}{2} [/tex]
The possible solution of the system is the ordered pair (x,y)
[tex] (x,y) = ( \frac{27}{8} , 18)[/tex]

A steel company sells 144 tons of steel every 3 years.
At this rate, what is the unit rate for the amount of steel sold every year. You can make a ratio table to help you think through this problem.
Answer:
48 tons of steel per year
Step-by-step explanation:
you can make it a ratio problem but you can also divide it
144 tons : 3 years
? : 1 year
take 144/3 and you get
48 tons
so
48 tons : 1 year
Answer:
Unit rate= 36
Step-by-step explanation:
Divide 144 by 4 and you get 36. So, the steel company made 36 tons of steel in 1 year and made 144 tons of steel in 4 years
A number from 0 to 9 is randomly selected and then a letter from A to D is randomly selected. What is the probability that the number 3 and a consonant are selected?
Answer:
[tex]\frac{1}{10}*\frac{3}{4} =\frac{3}{40}[/tex]
Step-by-step explanation:
There are 10 numbers 0,1,…9
Probability that 3 is selected is [tex]\frac{1}{10}[/tex]
Again, there are 4 letters A,B,C & D of which 3 are consonants and 1 is vowel. So, probability of selecting a consonant is [tex]\frac{3}{4}[/tex] . Hence, the required probability is [tex]\frac{1}{10} *\frac{3}{4} = \frac{3}{40}[/tex]

Step-by-step explanation:
Given,GRAM is a parallelogramRG = 19RP = 12AR = 15Solution:i) Since,
Diagonals of a parallelogram bisect each other so,
RM = 2 × RP
=> RM = 2 × 12
=> RM = 24 (Ans)(i)
ii) Since,
Opposite sides of a parallelogram are equal so,
GM = AR = 15
=> GM = 15 (Ans)(ii)
iii) Since,
Opposite sides of a parallelogram are equal so,
AM = RG = 19
=> AM = 19 (Ans)(iii)
Given :
GRAM is a parallelogram where
RG = 19RP = 12AR = 15Solution :
We know that,
Opposite sides of a parallelogram are equal in length.Diagonals of a parallelogram bisect each other.So,
RG = 19
⇢ RG = AM [Opposite sides]
⇢ AM = 19 .
Since,
⠀⠀RP = 12
⇢ RM = 2(RP) [Diagonals bisect each other]
⇢ RM = 2(12)
⇢ RM = 24
Since,
⠀⠀AR = 19
⇢ AR = GM [Opposite sides]
⇢ GM = 15 .

A: game 1 ( 200 points per hit)
B: game 2 (points double on each hit)
C: It depends
Explain your answer.
Answer:
Game 2
Step-by-step explanation:

Example:
1x2=2, 2x2=4, 4x2=8, 8x2= 16, 16x2=32, and so on.
Answer:
It Depends
Step-by-step explanation:
Sample Answer: For up to 11 hits, Game 1 gives the player higher scores. But for 12 or more hits, Game 2 does. That's because exponential growth eventually exceeds linear growth.

Math Whizzes I have freshman question-
On a coordinate plane, an exponential function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 4).
What is the initial value of the exponential function shown on the graph?
0
1
2
4
Answer:
4
Step-by-step explanation:
Exponential functions are written in the form [tex]f(x)=ab^x[/tex]
[tex]a[/tex] is the initial value of an exponential function and is found by substituting [tex]x=0[/tex] into the function as [tex]b^0=1[/tex]
Therefore, as y = 4 when x = 0, the initial value is 4
Solve by elimination:
4x+2y=8
8x+4y=16
Answer:
x = 1
y = 2
Step-by-step explanation:
for the first one it is that because 4 * 1 = 4 and then 2 * 2 equals 4 so 4 + 4 = 8
For the second one it is that because 8 * 1 = 8 and then 4 * 2 = 8 so 8 + 8 = 16!

The function g(x) is graphed. Which statements about the function are true? Choose three options. O g(1) = -1 O g(0) = 0 O 94) = -2 -5 O g(1) = 1 O g- 1) = 1 in
Answer:
g(0) = 0
g(1) = 1
g(-1) = 1
Step-by-step explanation:
g(1) = -1 means that when 1 is inputted into the function, the output is -1.
Therefore, y = -1 when x = 1. From inspection of the graph, when x = 1, y = 1, therefore this is untrue.
g(0) = 0 ⇒ y = 0 when x = 0. From inspection of the graph, when x = 0, y = 0. Therefore this is true.
g(4) = -2 ⇒ y = -2 when x = 4. From inspection of the graph, we cannot read when x = 4, but y > 0 when x = 4. Therefore this is untrue.
g(1) = 1 ⇒ y = 1 when x = 1. From inspection of the graph, when x = 1, y = 1. Therefore this is true.
g(-1) = 1 ⇒ y = 1 when x = -1. From inspection of the graph, when x = -1, y = 1. Therefore this is true.
16. In Chapter 5, you discovered that when you construct the three midsegments in a triangle, they divide the triangle into four congruent triangles. Are the four triangles similar to the original? Explain why or why not
Answer:
A midsegment is the line segment connecting the midpoints of two sides of a triangle. Since a triangle has three sides, each triangle has three midsegments. A triangle midsegment is parallel to the third side of the triangle and is half of the length of the third side.

You have a coupon for 20% off your total. Your total comes to $45.26. How much will you get off your total?
Answer:
$9.05
Step-by-step explanation:
We need to find 20% of 45.26
20% = 20/100 = 1/5 = 0.2
Of is related to multiplication
So, 20% OF 45.25 is 0.2 times 45.26
0.2 * 45.26 = 9.052
9.052 needs to be rounded to 9.05
The answer is $9.05

which statement best explain best explains whether the table represents a linear or non linear function (100 POINTS) HURRYYYY PLSSS
Answer:
It is a linear function because there is a constant rate of change in both the input and output values
Step-by-step explanation:
To determine if the function is linear, calculate the differences between the y values.
If the differences are constant, or the same value, the equation is linear and has a constant slope. If the differences are not the same, the equation is not linear.
difference between y values (output)
7 - 4 = 3
3 - 1 = 3
1 - -2 = 3
⇒ the function is linear
difference between x values (input)
-2 - -5 = 3
-5 - -8 = 3
-8 - -11 = 3
⇒ the function is linear as there is a constant rate of change in both the input and output values

A town is designing a rectangular park that will be 600 feet wide by 1000 feet long. On a scale drawing, the dimensions of the park are 12 inches wide by 20 inches long. A rectangular area of the park for swing sets is 0. 5 inch wide by 2 inches long on the scale drawing. What is the actual length of the swing set area of the park? Enter your answer in the box. The actual length of the swing set area of the park is feet.
Scale drawing takes scaled versions of original lengths. The actual length of the swing set area of the park is 25 ft long and 100 ft wide
How are scale drawings formed?For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means
[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]
All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.
For the given case, it is given that
Real dimension of a rectangular park : 600 ft by 1000 ft
In drawing, it was of 12 inches by 20 inches.
Let the scale that the drawing is using be k feet to s inches, then
[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]
Since it is given that 600 ft : 12 inches and 1000 ft : 20 inches, thus, we get:
[tex]\rm 1\: ft : \dfrac{s}{k}\: in.\\\\600 \: ft = \dfrac{600\times s}{k} \: in. = 12 \: in.\\\\\dfrac{600 \times s}{k} = 12\\\\\dfrac{s}{k} = \dfrac{12}{600} = 0.02[/tex]
Thus, every feet is reduced 0.02 times in drawing.
Now,
it is given that in drawing, the rectangular area for swing sets is 0.5 inch to 2 inch.
Let its real length was L and real width was W. Then we have:
[tex]\rm L \times 0.02 = 0.5 \\\\L = \dfrac{0.5}{0.02} = 25 \:\\\\W \times 0.02 = 2 \\W = \dfrac{2}{0.02} = 100[/tex]
Since these are only magnitudes, and unit was converted from feet to inches, so we have L = 25 feet and W = 100 feet
Thus,
The actual length of the swing set area of the park is 25 ft long and 100 ft wide
