Write an equation in slope for a line that passes through (3,4) (and has a y intercept of -8)

Vlad [161]

Answer:

Part 1) The equation in slope intercept form is $y=4x-8$

Step-by-step explanation:

Part 1) Write an equation in slope-intercept form for a line that passes through (3,4) (and has a y intercept of -8)

we know that

The equation of a line in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$b=-8$

$point\ (3,4)$

substitute

$4=m(3)-8$

solve for m

$4+8=3m$

$3m=12$

$m=4$

therefore

$y=4x-8$

A number cube is tossed 50 times, and a 1 is rolled 18 times. Find the experimental probability of not rolling a 1.

LiRa [457]

Answer:

16/25 = 0.64

Step-by-step explanation:

18 rolls are ones, so 32 rolls are not ones.

The experimental probability is 32/50 = 16/25 = 0.64.

I built a storage shed in the shape of a rectangular box on a square base. The material that I used for the base cost $4 per squ

Dmitrij [34]

Answer:

$V = \frac{450L - 6 L^{3} }{10}$

Step-by-step explanation:

The volume of a cuboid can be determined simply by the formula: V= LWH

(where: L is length, H is height and W is width).

In this particular case the base is a square, which means the length and width are equal. Hence we can modify the equation of volume:

$V = L^{2} H$

Now we need to find the value of H in terms of L. For this we can develop the equation for cost incurred in building the storage shed. We find the area of each side of the cuboid, and then we multiply it by cost per square feet to find the total cost incurred; as shown below:

Area:

Base: $L$ × $L = L^{2}$
