Answer:
Step-by-step explanation:
slope = (y2 - y1) / (x2 - x1)
(-3,-4)....x1 = -3 and y1 = -4
(-2,r)....x2 = -2 and y2 = r
slope = 10
now sub
10 = (r - (-4) / (-2 - (-3)
10 = (r + 4) / (-2 + 3)
10 = (r + 4) / 1.....multiply both sides by 1, eliminating the 1 on the right
10 * 1 = r + 4
10 = r + 4
10 - 4 = r
6 = r <======

Answer:
1 litre = 1000 millilitres (ml)
35 litres = 35×1000 => 35000 ml
So your fish tank holds 35000 ml of water
Answer:
B (although you failed to put the division bar between the 24 and the 5)
Step-by-step explanation:
The x-intercept exists where y = 0. So we plug in 0 for y and solve for x:
-5x + 3(0) = -24 and
-5x = -24 so
x = 24/5
The y-intercept exists where x = 0. So we plug in 0 for x and solve for y:
-5(0) + 3y = -24 and
3y = -24 so
y = -8
The coordinate for the x-intercept is (24/5, 0)
The coordinate or the y-intercept is (0, -8)
Choice B
Answer:
127/14
Step-by-step explanation:
39/7 + 7/2 = 78/14 + 49/14
78/14 +49/14 = 127/14
