Which graph shows the solution to the system of linear equations?
y equals one third x
x + 3y = −6
Answers
Answer:So let's start by guesstimating the slopes:
the green line has a slope close to -x, but more negative than that, possibly -2; the pink line has a slope close to +x, but higher towards +2.
Next let's look at the solution: the two lines intersect at the point (1, -1).
**you could just simple plug that x (1) into all the equations, but let's rule out answers anyway. ;)
A) is incorrect because the slopes of -1 and +1 are off from out predicted -2 and +2
B) is incorrect because of a similar reason, the slopes of +3 and +1 don't make any sense
C) Ooh, we do have a +2 and -2 for the slopes, and... violà! plug in 1 for the x's and we get -1 for the y in both equations
D) slopes are closer than in A and B, but plugging in 1 doesn't get us -1
So the correct answer is:
C) y = 2x - 3 and y = −2x + 1

Answer:
12a
12a = 96
Step-by-step explanation:
12a + (6a + 8) + (10a - 4) + (6a + 8) = 204
Combine like terms.
34a + 12 = 284
34a + 12 - 12 = 284 - 12
34a = 272
34a ÷ 34 = 272 ÷ 34
a = 8
Let's replace a and see.

1. The image is telling us that the circle's radius is 3 inches. To find the perimeter using radius, multiply the radius by two to get the full diameter. Then, multiply by π (3.14 in your case).
3 x 2 = 6 inches (diameter= 6 inches)
c=πd
c= 3.14 x 6
c=18.84 inches
∴The circumference is 18.84 inches.
3. The image is telling us that the diameter is 8 feet.
c=πd
c=3.14 x 8
c=25.12 feet.
∴The circumference of the circle is 25.12 feet.
7. This image is a semi-circle, which means that you may find the full diameter and divide by 2 (for half of the full circle).
c=πd
c=3.14 x 23
c=72.22 cm
72.22 ÷ 2= 36.11
∴The circumference 36.11 cm.

In baseball, each time a player attempts to hit the ball, it is recorded. The ratio of hits compared to total attempts is their batting average. Each player on the team wants to have the highest batting average to help their team the most. For the season so far, Jana has hit the ball 12 times out of 15 attempts. Tasha has hit the ball 9 times out of 10 attempts. Which player has a ratio that means they have a better batting average?
A:Tasha, because she has the lowest ratio since 0.9 > 0.8
B:Tasha, because she has the highest ratio since 27 over 30 is greater than 24 over 30
C:Jana, because she has the lowest ratio since 0.9 > 0.8
D:Jana, because she has the highest ratio since 27 over 30 is greater than 24 over 30

Answer:
61 in²
Step-by-step explanation:
Area 2 circles =
2( πr²)
1.5 x 1.5 = 2.25
2.25 x 3.14 = 7.065
7.065 x 2 = 14.130
Area rectangle =

2πr = 2(1.5 x 3.14) = 9.42

Answer:
4(x-1)+9=17
Step-by-step explanation:
3(-2x+1) + 5 = 3x-4-5x
expand
-6x + 3 + 5 = 3x-4-5x
-6x + 8 = -2x - 4
add 2x to both sides to put all x values + coefficients on one side
-4x + 8 = -4
subtract 8 from both sides to isolate x and its coefficient
-4x = -12
divide both sides by -4 to isolate x
x = 3
plug x=3 into each option to see if it works
1. 5(3+3)-4 = 30-4 = 26 != 10

Ava bought snacks for her team's practice. She bought a bag of oranges for $2.71 and a 4-pack of juice bottles. The total cost before tax was $6.75. Write and solve an equation which can be used to determine jj, how much each bottle of juice cost.
Answers
Answer: Let j be the cost of each juice bottle.
The total cost of the juice bottles is 4j. The total cost of the oranges and juice bottles is $6.75.
Thus, the equation that represents the given information is: 4j + $2.71 = $6.75. Subtract $2.71 from both sides to get: 4j = $4.04. Divide both sides by 4 to get: j = $1.01.
Therefore, each juice bottle costs $1.01.
Step-by-step explanation:
Total cost = cost of a bag of oranges + cost of 4-pack juice bottles
$6.75= $2.71 + (4 x jj)
$6.75 = $2.71 + 4jj
take similar terms: $6.75 - $2.71 = 4jj
Add similar terms: $4.04 = 4jj
Divide both sides of the equation by 4: jj = $4.04 / 4=
jj = $1.01
