It’s 163, first you have to solve for inside the parentheses which is 75 then 75 plus 93 is 163

it's not that hard girl by like I'm too lazy to do the last one
Answer=B
36 red marbles
64 blue marbles
red marbles:blue marbles
36:64
now lets simplify the ratio by dividing both numbers by 2
18:32
continue simplifying by dividing both sides by 2 again...
9:16
The ratio of red to blue marbles is 9:16
Answer:
(9.2 , 0)
Step-by-step explanation:
vertex: (4.6 , 12.2)
parabola: y = a (x-4.6)² + 12.2
pass (0,0): 0 = a (0-4.6)² + 12.2
a = - (12.2/21.16)
2nd root (x , 0): y=0
0 = a (x-4.6)² + 12.2 (x-4.6)² = - 12.2 / a = -12.2 / (- (12.2/21.16)) = 21.16
x - 4.6 = ± √21.16 = ± 4.6
x = 0 or x = 9.2
Answer:
Step-by-step explanation:
A parallel line will have the same slope, m, as the reference line given by the form y=mx+b. b is the y-intercept, the value of y when x=0.
The reference line of y = -(1/2)x + (3/7) has a slope of -(1/2).
The parallel line will have the same slope, so we can write:
y - -(1/2)x + b
We need a value of b that forces the line to go through point (-1,0). Enter that point in the equation and solve for b:
y - -(1/2)x + b
0 - -(1/2)(-1) + b
b = -(1/2)
The equation of the line parallel to y = -(1/2)x + (3/7) and going through (-1,0) is
y=-(1/2)x - (1/2)
