Write the standard form of the line that has a slope of -3/4 and y-intercept of -2. Include your work in your final answer. Type

Nataliya [291]

3x + 4y = - 8

The equation of a line in standard form is Ax + By = C

where A is a positive integer and B, C are integers

Express the line in ' slope- intercept form '

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

here m = - $\frac{3}{4}$ and c = - 2

hence y = - $\frac{3}{4}$ x - 2 → equation in slope- intercept form

multiply all terms by 4

4y = - 3x - 8

add 3x to both sides

3x + 4y = - 8 → in standard form

A toy rocket is lunch vertically upward from ground level in into velocity of one 28 ft./s how long will it take for the rocket

pentagon [3]

Answer:

1.14 s

Step-by-step explanation:

Time, $t=\frac {d}{s}$

Here, d is the distance and s is the speed/velocity

Since we're given the velocity, s as 28 ft/s and the distance between the position of the rocket and ground as 32 ft then

$t=\frac {32}{28}=1.142857143\approx 1.14 s$

Therefore, it needs 1.14 seconds

The solid surface area is equal to the solid volume. Find the value of x? The measurements of the rectangular prism is 9 inches

Fudgin [204]

Answer:

$x=7.2$

Step-by-step explanation:

Let x represent height of the prism.

We know that volume of rectangular is equal to product of its height, width and length.

$\text{Surface area of rectangular prism}=2(wl+lh+hw)$ , where w, h and l represents width, length and height respectively.

We have been given that the surface area of rectangular prism is equal to the volume of the prism. So we can set an equation as:

$lwh=2(wl+lh+hw)$

We are also told that the measurements of the rectangular prism is 9 inches long and 4 inches wide. Upon substituting these values in above equation, we will get:

$9\cdot 4\cdot x=2(4\cdot 9+9\cdot x+x\cdot 4)$
