Answer:
x-2y=4
Step-by-step explanation:
So from the question we know the following:
When something is x intercept it means y=0 so we have (4,0)
When something is y intercept it means x=0 so we have (0,-2)
Now you use these to find the slope using the formula m= (y2-y1)/(x2-x1)
Plug in the values
m= (-2-0)/0-4)
m=(-2/-4)
m= 1/2
x-2y=4
Now you just plug this in slope intercept form y=mx+c, where c is y intercept
y=1/2 x -2
Standard form: ax+by=c
y=1/2 x -2 (rearrange to match the above equation)
-1/2 x +y =-2 (multiply both sides by 2 because we can't have a fraction for a in the standard form)
-1x+2y=-4 (now multiply both sides by -1 because a cannot be negative)
x-2y=4
Ok, so
a(b-c)=ab-ac
9 is close to 10 so
828(9)=
828(10-1)=
828(10)-828(1)=
8280-828=
7000+1280-828=
7000+452=
7452
I hope this helps you

Answer: Probability is 0.00205 = 0.205%
Step-by-step explanation: P(rain) = 0.71, P(no rain) = 0.29.
P(no rain in 5 days)= 0.29·0.29·0.29·0.29·0.29= 0.00205
Question #1: Abby ended her walk at school.
Question #2: Abby and Bryan walk 9 blocks after school together to go to the grocery store and the park. After they leave the park, Bryan has to walk 5 blocks, and Abby has to walk 9 blocks to get home. Therefore Abby has to walk 4 more blocks than Bryan does.
Answer: 4 Blocks.
