Ursula and Andre competed against each other in a swimming race. Ursula swam at a rate of 60 meters per minute and Andre swam at

Lubov Fominskaja [6]

Given that the two swimmers competed and Ursula's speed is 60 m/min while Andre's speed is 48 m/min. The distance that the Ursula will catch up with Andre will be:
distance=(relative speed)×(time)
relative speed=60-48=12 m/min
the two swimmers met at a distance of:
12×1
=12 meters

what is the point slope form of an equation with the slope of 3/5 that passes through the point (10,-2)?

Mama L [17]

Point slope form of a line:
$y-y_1=m(x-x_1)$ where $m$ is your slope and $(x_1,\ y_1)$ is a point on your line.

For a line with a slope of 3/5 that passes through (10, -2)...
$m=\frac35,\ x_1=10,\ y_1=-2$
Let's plug these values into our formula.

$y-(-2)=\frac35(x-10)$

Subtracting by a negative is the same thing as adding (the double negatives cancel), so let's simplify that.

$\boxed{y+2=\frac35(x-10)}$

There's our equation in point-slope form. (keep in mind that you're not going to want to distribute that 3/5 or subtract the 2 or anything. You want to keep it similar to the formula.

The functions below represent the amounts of water released from two reservoirs over x weeks:

solong [7]

Answer:

h(x) = -2x^2 -x +3
Reservoir A releases the same amount of water as Reservoir B over 1 week

Step-by-step explanation:

Given:

f(x) = x^2 -7x +5

g(x) = 3x^2 -6x +2

h(x) = f(x) -g(x)

Find:

h(x)

h(1)

Solution:

The expression for h(x) is found by evaluating its definition:

h(x) = (x^2 -7x +5) -(3x^2 -6x +2)

h(x) = x^2(1 -3) +x(-7 -(-6)) +(5 -2)

h(x) = -2x^2 -x +3

Then h(1) is found by substituting 1 for x:

h(1) = -2(1^2) -(1) +3 = -2 -1 +3

h(1) = 0 . . . . difference in release amounts after 1 week is 0

The true statements are ...

h(x) = -2x^2 -x +3
Reservoir A releases the same amount of water as Reservoir B over 1 week
