Answer:
Step-by-step explanation:
[1] 3x - 4y = -24
[2] -x - 16y = -52
Graphic Representation of the Equations :
-4y + 3x = -24 -16y - x = -52
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -16y + 52
// Plug this in for variable x in equation [1]
[1] 3•(-16y+52) - 4y = -24
[1] - 52y = -180
// Solve equation [1] for the variable y
[1] 52y = 180
[1] y = 45/13
// By now we know this much :
x = -16y+52
y = 45/13
// Use the y value to solve for x
x = -16(45/13)+52 = -44/13
Solution :
{x,y} = {-44/13,45/13}
Answer: The slope is -8/3
Step-by-step explanation: Use the slope formula y2-y1/x2-x1
so -9-7/2-(-4) = -16/6 which can be divided by 2 to get -8/3
Answer:
<em><u>A theater has </u></em><em><u>60 seats</u></em><em><u> in the first row, 68 seats in the second row, 76 seats in the third row,</u></em>
<em><u>and so on in the same i</u></em><em><u>ncreasing pattern</u></em><em><u>. If the theater has</u></em><em><u> 20 rows of seats, how many seats are in the theater?</u></em>
220 seats in the theater.
So if the increasing pattern is +8, and we need to determined how many seats there will be if there where 20 rows, then you would need to multiply.
1. 8 x 20 = 160
2. 160 + 60 = 220
Answer:she has 120 apples left.
Step-by-step explanation:
Total number of apples that Lexi had in her basket to sell is 300.
If she dropped 122 apples on the ground because she can't use them and sell them, then the number of apples that she has left for sale is
300 - 122 = 178
If then after she sells 58 apples, the number of apples that she has remaining would be
178 - 58 = 120 apples
