Answer:
y=-3x+10
Step-by-step explanation:
Slope formula y2-y1/x2-x1
7-1/1-3
simplify
6/-2
simplify
-3
now plug -3 into y=mx+b
y=-3(x)+b
choose any point and plug it into the equation, I am using (3,1)
1=-3(3)+b
simplify
1=-9+b
add 9 to both sides
b=10
plug into slope-intercept form
y=-3x+10
Answer:
2.5 miles
Step-by-step explanation:
We know that: time = distance/speed
Now, if the distance of the school from Jonathan's home is y.
At speed of 15 mph, Jonathans time is; time = y/15 hours
At 25 mph, his mother's time was;
time = y/25 hours
We are told that Jonathan was 1 mile from home when he saw his mother.
Thus means that difference in time is;
Time difference = 1/15 hours
Thus;
y/15 hours - y/25 hours = 1/15 hours
Multiply through by 75 to get;
5y - 3y = 5
2y = 5
y = 5/2
y = 2.5 miles
1/2+1/8+1/4=7/8
4/8+1/8+2/8=7/8
1-7/8 = 3/8
the fourth on inherited 3/8 of the estate.
Hello from MrBillDoesMath!
Answer:
Choice B.
Discussion:
From the first step
324 x^6 y^ 8 =
2^2 * 3^4 * x^2 * x^4* y^8
so the fourth root of this is
2 ^(2/4)* 3^(4/4) x^(2/4)* x^(4/4)*y^(8/4) =
2^ (1/2) * 3^1 * x^(1/2) * x^(1)* y^ (2) =
(2x)^(1/2) * 3 * x * y^2 =
3 * x * y^2 * sqrt(2x) =
3 * x * y^2 * ( (2x)^2) ^ (1/4)) =
3 * x * y^2 * (4x^2) ^ (1/4)
which is choice B
Thank you,
MrB
Baso 6 divided by 2 is 3 that’s what the question is saying
