Answer:
a = 23
b = 10
Step-by-step explanation:
The general formula is
y = 3x + 5
Just to check, let x = 2
y = 3*2 + 5
y = 6 + 5
y = 11
And a confirmation check
x = 3
y = 3*3 + 5
y = 9 + 5
y = 14
So for a
x = 6
y = 6*3 + 5
y = 18 + 5
y = 23
For b, you know y
35 = 3x + 5
<u>- 5 -5 </u> Subtract
30 = 3x Divide by 3
30/3 = 3x/3
x = 10
Answer:
The reason Statement 1 can be both forward and reverse is because is Bo and Mel are related then it will word forward and backward.
The reason Statement 2 can be only forward is because is the sprinklers are on then the grass is wet will work since it is saying ONLY the sprinklers are on. If it is reverse and the grass is wet if the sprinklers are ONLY on than that is false since if it rains than the grass can also be wet. So there are multiple ways that the grass can be wet hence the answers.
The middle point of BC is (0,2), the midpoint of CD is (1,0)
to prove two lines are parallel, prove their slopes are the same.
slope of BD: m=rise/run=4/-2=-2 (the run is negative because to get to B from D on the grid, you have to move from right to left, then upward. If the horizontal move is from left to right, the run is positive)
slope of EG: m=rise/run=2/-1=-2
EG and BD have the same slope, so they are parallel.
And or both means we multiply the given probability situations that are mutually exclusive and exhaustive - they cannot occur at the same time.
let P(a)=x
then: P(b) * P(a) =3/4
15/16 * x = 3/4
15x/16 = 3/4
therefore x= 3/4 *16/15
x = 4/5
P(a) = 4/5
hope it's clear
