What is the slope and y intercept of the linear equation y=5x-4

1 answer:

3 0

The slope is 5
the y intercept is -4

slope intercept form is: y=mx+b

M is always the slope, b is the y intercept.

Hope I helped!

Harlamova29_29 [7]

To answer this question you would set this up as an equation with all the information about Al on one side being equal to all the information for Matthew on the other side. This is what it would look like: $25 + $9h= $14h. h represents the number of hours they work. It they each worked 5 hours a week, they would make the same amount of money. I determined this by solving the equation for h. I subtracted 9h on both sides leaving you with $25=5h. H would equal 5 hours.

Two families visited an amusement park. The first family bought 2 hot dogs and 3 bottles of waters, which totaled $18. The secon

Ghella [55]

Answer:

$6.00

Step-by-step explanation:

To solve this problem, we have to construct two separate equations for each family, and then use any of the methods for solving simultaneous equations.

Let's consider h to represent the cost of 1 hot dog, and w to mean the cost of 1 water bottle.

• For the first family:

$2h + 3w = 18$

We can rearrange the equation to make w the subject:

⇒ $3w = 18 - 2h$

⇒ $w = \frac{18 - 2h}{3}$

• For the second family:

$4h + 2w = 28$

Since we have previously obtained an expression for w in terms of h, we can substitute that expression for w in the above equation, and then solve for h:

⇒ $4h + 2(\frac{18 - 2h}{3}) = 28$

⇒ $4h + \frac{36 - 4h}{3} = 28$

⇒ $12h + 36 - 4h = 84$ [Multiplying both sides of the equation by 3]

⇒ $8h + 36 = 84$

⇒ $8h = 48$

⇒ $h = \bf 6$

∴ The price of one hot dog is $6.00.

a cookie baker has an automatic mixer that turns out a sheet of dough in the shape of a square 12 inches wide. His cookie cutter

iragen [17]

Answer:

All the sizes that satisfy $kd^2 =144$

Step-by-step explanation:

To answer this question we first need to find the minimum wasted area of the dough.

Let us call the diameter of the cookie $d$ , and $a$ the length of the dough sheet, then the $n$ number of cookies that fit into length $a$ will be

$n = \dfrac{a}{d}$

and therefore, the number that will fit into the whole square sheet will be

$n^2 = \dfrac{a^2}{d^2}$

Since the area of each cookie is

$A = \pi \frac{d^2}{4}$

the area of n^2 cookies will be

$A_n = n^2\pi \frac{d^2}{4}$ ,

which is the area of all the cookies cut out from the dough sheet; therefore, after the cutting, the area left will be

(1). $\text{area left}= a^2-n^2\pi \frac{d^2}{4}$

putting in the value of $n^2$ we get

$a^2- \dfrac{a^2}{d^2}\pi \frac{d^2}{4}$

which simplifies to

area left = a^2( 1 - (π/4))

putting in a = 12 we get

area left = 30.902 in^2.

Going back to equation (1) we find that

a^2-n^2(πd^2/4) =30.902

12^2- n^2(πd^2/4) =30.902

and if we call k = n^2, we get

12^2- k(πd^2/4) =30.902

113.098 = k(πd^2/4)

simplifiying this gives

kd^2 = 144.

As a reminder, k here is the number of cookies cut from the dough sheet.

Hence, our cookie diameter must satisfy kd^2 = 144, meaning larger the diameter of the cookies less of the should you cut out to satisfy the above equality.
