Two lines, A and B, are graphed (Look at the picture):
Determine the solution and the reasoning that justifies the solution to the systems of equations.
a.(−4, 6), because both the equations are true for this point
b.(2, 8), because the graph of the two equations intersects at this point
c.(2, 8), because neither of the two equations is true for this coordinate point
d.(−4, 6), because the graph of the two equations intersects the axis at these points
Answers
Answer:
B. (2,8), because both equations intersect at this point
Answer:
B. (2,8), because both equations intersect at this point
Step-by-step explanation:
Why is it answer B? Because of Enlarging the graph, we find that the intersection of the two lines drawn is at point (2,8). Hence, the solution of the equation is (2,8) because the graphs of the two lines intersect at this point.

71 degrees
Step-by-step explanation:
All angles in a triangle must add up to 180 degrees. If we take that total 180 and subtract 38, we get 142 degrees. If we divide that by two, because the angles are the same, we get 71 degrees. Therefore x=71

A metallurgist wants to make 130 grams of an alloy that is to be 20% copper. She has samples that are 14% copper and 22% copper. How many grams of the sample that contains 14% should she use?
Answers
Answer:
She should use 32.5 g of the sample that contains 14%
Step-by-step explanation:
Here, we want to know the number of grams of the sample that contains 14% copper that should be used
let the number of grams that contains 14% copper to be used be x
Then the number of grams of 22% will be 130-x
Thus, mathematically;
0.14(x) + 0.22(130-x) = 0.2(130)
0.14x + 28.6 - 0.22x = 26
0.22x - 0.14x = 28.6 - 26
0.08x = 2.6
x = 26/0.08
x = 32.5
A 1/2 cup serving of ice cream contains 140 calories. How many calories would be in a 3/4 cup serving?
Answers
Answer:
There would be 210 calories in a 3/4 cup serving.
Step-by-step explanation:
1/2 of 140 = 70
70 = 1/4
70 x 3 = 210 = 3/4
I hope this helped you! If it did, please consider pressing thanks, rating my answer, and marking as Brainliest. It would be a big help! Have a great day! :)
Based on the number of calories in 1/2 cups, the number of calories in 3/4 cups is 210 calories.
Number of calories in 3/4 cupYou can use direct proportion to solve for this by assuming that the calories in 3/4 cups is x:
1 / 2 : 140 calories
3 / 4 : x
Cross multiplying would give:
1/2x = 105
x = 105 ÷ 1/2
x = 210 calories
In conclusion, there would be 210 calories in 3/4 cups.

the bat is 12. the pumpkin is 5. and the weird looking thing is 14
14 plus 14 plus 12 is 40
12 minus 5 is 7
5 plus 14 is 19
14 minus 5 plus 12 is 21
Answer:
21
Step-by-step explanation:
Green bat: x
Purple bat: y
Pumpkin: z
Given:
2x + y = 40
y - z = 7 ===> y = 7 + z
z + x = 19 ===> z = 19 - x
Substitution to find green bat x:
2x + y = 40
2x + (7 + z) = 40
2x + 7 + z = 40
2x + 7 + (19 - x) = 40
2x + 7 + 19 - x = 40
x + 26 = 40
green bat: x = 14
Substitution to find pumpkin z:
z + x = 19
z + (14) = 19
z + 14 = 19
pumpkin: z = 5
Substitution to find purple bat y:
y - z = 7
y - (5) = 7
y - 5 = 7
purple bat: y = 12
Solve for x - z + y:
14 - 5 + 12 = 21
