y=2x-8
13x + 2y = 18
solving systems by the elimination method
Answer:
x = 2
Step-by-step explanation:
13x + 2( 2x - 8) =18
13x + 4x -16 = 18
13x + 4x = 34
17x = 34
x = 2
1 Graph a line that contains the point (4,3) and has a slope of 1/2
(numbers on graph go up to 7)
Answer:
the points: (8,5) (6,4) (4,3) (2,2) (0,1) (-2,0) (-4,-1) (-6,-2) (-8,-3)
Step-by-step explanation:
the point (4,3) should be dotted first, start from the (0,0) go right 4 spaces then up 3 spaces. the slope 1/2 means up 1 space then right two spaces to start plotting points on the graph. and to continue the bottom of the line it would be -1/-2 which is down 1 space then left 2 spaces.
find the common ratio and the 12th term of the geometric sequence 64, 16, 4, ...
Answer:
common ration = 1/4
12th term = 1/65536
Step-by-step explanation:
64
64*1/4 = 16
16 * 1/4 = 4
4* 1/4 = 1
1 * 1/4 = 1/4
1/4*1/4 = 1/16
1/16*1/4 = 1/64
etc
1/256
1/1024
1/4096
1/16384
12th term = 1/65536
Answer:
see explanation
Step-by-step explanation:
The common ratio r is calculated as
[tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{16}{64}[/tex] = [tex]\frac{1}{4}[/tex]
The n th term of a geometric sequence is
[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 64 and r = [tex]\frac{1}{4}[/tex] , thus
[tex]a_{12}[/tex] = 64 × [tex](\frac{1}{4}) ^{11}[/tex] = 64 × [tex]\frac{1}{4194304}[/tex] = [tex]\frac{64}{4194304}[/tex] = [tex]\frac{1}{65536}[/tex]

Consider the equation 1.2x + 4.8y = 18
If we graph the equation, what is the slope of the graph?
Answer:
-1/4
Step-by-step explanation:
For this equation, first divide both sides by 1.2, to get x+4y=15. Then, subtract x from both sides. Now, with 4y=-x+15, divide by 4. You should get y=-1/4x+15/4 (15/4=3 3/4 or 3.75). The formula y=kx=b, where k is slope, means the slope is -1/4.

The value of investments in the stock market change daily. Suppose you buy a stock for $3,789. It increases in value by 6% and then decreases 7% and then increases again by 7%. What is the new value? (round your answer to the nearest cent)
Answer:
The final value of the stock is $3,996.66
Step-by-step explanation:
Percentage Change
The x% of a number N is calculated as x*N/100. If there is an increase, that number is added to the original value, then the new value is:
N'=N+x*N/100
Operating:
N'=N(1+x/100)
That formula makes it easier to find the new values of increasing quantities. When the percentage is for decreasing, then the formula becomes:
N'=N(1-x/100)
The original value of the stock is N1=3,789. The first change is an increase of 6%, then the new value is:
N2=3,789(1+6/100)=3,789*1.06=$4,016.34
The stock value now decreases by 7%:
N3=4,016.34(1-7/100)=4,016.34*0.93=$3,735.20
Finally, the value increases again by 7%:
N4=3,735.20(1+7/100)=3,735.20*1.07=$3,996.66
The final value of the stock is $3,996.66

Eva, Josh, and David gather and shell pecans for their mother. Eva gathers 2 1/2 pounds of pecans, Josh collects 3.25 pounds, and David harvests 4 3/8 pounds. If they place all the pecans in one basket and each shells the same amount of pecans, how many pounds would each person shell? Group of answer choices
Answer:
3.375 pounds.
Step-by-step explanation:
Total number of pounds of pecans =
2 1/2 pounds of pecans + 4 3/8 pounds + 3.25 pounds
= (6.875 + 3.25) pounds
= 10.125 pounds.
The total number of person = 3 person.
Therefore, the number of pounds each person would shell =
10.125 pounds/3
= 3.375 pounds

Explain how to solve 2(x+3) = 10. What properties did you need to solve the equation?
Answer:
x = 2, Inverse property of subtraction
Step-by-step explanation:
Simplifying
2(x + 3) = 10
Reorder the terms:
2(3 + x) = 10
(3 * 2 + x * 2) = 10
(6 + 2x) = 10
Solving
6 + 2x = 10
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 2x = 10 + -6
Combine like terms: 6 + -6 = 0
0 + 2x = 10 + -6
2x = 10 + -6
Combine like terms: 10 + -6 = 4
2x = 4
Divide each side by '2'.
x = 2
Simplifying
x = 2
Answer:
x = 2
Step-by-step explanation:
Apply the distributed property, so it now looks like this: 2x + 6 = 10Subtract 6 to each side, so it now looks like this: 2x = 4Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 2I hope this helps!
You play a game where you score -6 points on the first turn and on each of the next 3 turns. Your score after those 4 turns is
Answer:
-24
Step-by-step explanation:
You start with -6 points, and get another -6 on the rest of the turns which is a total of 4 turns.
-6 x 4 is -24
Unless this question is missing some information, this should be correct I believe.
Hope this helps!
The score after 4 turns is -24.
Given that, you play a game where you score -6 points on the first turn and on each of the next 3 turns.
We need to find what is the score after 4 turns.
What are integers?An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.
Now, the score after 4 turns = Score of the first turn + The next 3 turns
= -6 + 3(-6)
=-6-18
=-24
Therefore, the score after 4 turns is -24.
