What is the slope of the equation y = 3/4 X + 8? A 3/4 B 8 C 3 D 4

Stels [109]

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

y = $\frac{3}{4}$ x + 8 ← in slope- intercept form

with slope m = $\frac{3}{4}$ → A

An ice cube is melting, and the lengths of its sides are decreasing at a rate of 0.8 millimeters per minute At what rate is the

julia-pushkina [17]

Answer:

The rate of decrease is: $43.2mm^3/min$

Step-by-step explanation:

Given

$l = 18mm$

$\frac{dl}{dt} = -0.8mm/min$ ---- We used minus because the rate is decreasing

Required

Rate of decrease when: $l = 18mm$

The volume of the cube is:

$V = l^3$

Differentiate

$\frac{dV}{dl} = 3l^2$

Make dV the subject

$dV = 3l^2 \cdot dl$

Divide both sides by dt

$\frac{dV}{dt} = 3l^2 \cdot \frac{dl}{dt}$

Given that: $l = 18mm$ and $\frac{dl}{dt} = -0.8mm/min$

$\frac{dV}{dt} = 3 * (18mm)^2 * (-0.8mm/min)$

$\frac{dV}{dt} = 3 * 18 *-0.8mm^3/min$

$\frac{dV}{dt} = -43.2mm^3/min$

Hence, the rate of decrease is: 43.2mm^3/min

Need help on this question I have

nataly862011 [7]

Answer:

y = 3x - 6

Step-by-step explanation:

Slope-interecept form is a "fill-in-the-blank" formula for writing the equation of a line. It is in the form:

y = mx + b

You fill in the slope for m and fill in the y-intercept for b.

You could totally graph these points and see the slope and y-intercept. But here's how to find them on the table.

When x is 0, y is -6. The y-intercept is where x is 0. So here, the y-intercept is -6. That is b. Fill in -6 in place of b.

y = mx + -6

Next pick any two points. I'm using the last two (3,3) and (4,6). Subtract the y's. 6-3 is 3, put that on top of a fraction. Subtract the x's, 4-3 is 1. Put that on the bottom of a fraction. That is the slope, 3/1. That is the m. Fill it in.

y = 3/1 x + -6

Clean it up (simplify)

y = 3x - 6
