Y= -4x+3
slope is still the same so it would be parallel to that line. Only the y-intercept is different so it would just pass through a different point
4x + 7y = 1 ⇒ 12x + 21y = 3
3x + 10y = 15 ⇒ <u>12x + 40y = 60</u>
<u>-19y</u> = <u>-57</u>
-19 -19
y = 3
4x + 7(3) = 1
4x + 21 = 1
<u> - 21 - 21</u>
<u>4x</u> = <u>-20</u>
4 4
x = -5
(x, y) = (-5, 3)
The factory made 7 batches of granola bars yesterday.
Answer:
x can equal to anything that is 1 and higher
Step-by-step explanation:
The equation is already correct, you just want to get x as a number that would increase the value.
Answer:
The perimeter of the rectangle is 26 cm
Step-by-step explanation:
First find the area of the square by multiplying 6 by itself
A = 6 cm * 6 cm = 36 sq cm
Since the rectangle has the same area as the square, we can say that w * 9 = 36 sq cm
w * 9 = 36
Divide both sides by 9 to isolate the variable, w
w * 9 / 9 = 36 / 9
w = 4 cm
The width of the rectangle is 4 cm so now we just use that to find the perimeter of the rectangle
P = 2(9) + 2(4) = 26 cm
