3 0

This point falls on none of your possible answers.

We can first tell that it falls neither positive or negative in terms of x since the x value is 0.

We can also tell the y term is negative. Therefore, it would fall on the negative y-axis.

What is −4(−5x+2)−3x−5= -30

alexandr1967 [171]

Answer:

x = -1

Step-by-step explanation:

Step 1: Write equation

-4(-5x + 2) - 3x - 5 = -30

Step 2: Solve for x

Distribute -4: 20x - 8 - 3x - 5 = -30

Combine like terms: 17x - 13 = -30

Add 13 on both sides: 17x = -17

Divide both sides by 17: x = -1

A boat traveled 280 miles downstream and back. The trip downstream took 7 hours. The trip back took 14 hours. Find the speed of

Brrunno [24]

Let, the speed of boat = x
Speed of current = y
So, x + y = 280/7
x + y = 40 ---- first equation

x - y = 280/14
x - y = 20
x = 20 + y

Substitute this value of x in first equation,
20 + y + y = 40
2y = 40 - 20
y = 20/2
y = 10

Substitute this in first equation,
x + 10 = 40
x = 30

In short, Speed of Boat = 30 mph, & speed of current = 10 mph

Hope this helps!

Find the slope of the line that passes through the pair of points (2,6) , (7,0)

iVinArrow [24]

Slope is defined as the change in y-coordinate over the change in x, so if you find the change then you can find the slope.
$\frac{change~in~y}{change ~in~x} =\frac{0-6}{7-2}=\frac{-6}{5}$
Thus, your slope is -6/5.
