First lets see what information they give us.
We know that they arrived with 6 gallons of gas and along the way they pumped 18 gallons and used 5.
(i got 18 by adding 8 and 10 just to make it simpler)

The table shows the price for shoe rental, games, and snacks at the bowling alley

monitta

First, find the total price she would have had to pay (without tax):
2.75+ 3(2.5)+ 1.75=12
If she has half-price multiply the total price by 0.5:
12(.5)=6
Her total price without tax is $6.

The answer is B) $6.00
Hope I helped...

You are given the hyperbolic relation modeled by xy=−3

jasenka [17]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

Let's solve :

a.) The equation will be :

$xy = - 3$

$y = \dfrac{ - 3}{x}$

b.) the table will be like this :

for x = 1 , y = -3

point (1 , -3)

for x = 3 , y = -1

point (3, -1)

for x = -1 , y = 3

point (-1 , 3)

for x = -3 , y = 1

point (-3 , 1)

c.) graph the equation as shown in attachment !

Factor. Explain.<br> 24x³y²-4x²y+84x^4

Elan Coil [88]

Answer:

$\boxed{\bold{4x^2\left(6xy^2-y+21x^2\right)}}$

Step By Step Explanation:

Apply Exponent Rule $\bold{\:a^{b+c}=a^ba^c}$

$\bold{x^4=x^2x^2,\:x^3y^2=x^2x}$

$\bold{24x^2x-4x^2y+84x^2x^2}$

Rewrite 84: $\bold{21\cdot \:4}$

Rewrite 24: $\bold{6\cdot \:4}$

$\bold{6\cdot \:4x^2x-4x^2y+21\cdot \:4x^2x^2}$

Factor Out Common Term $\bold{4x^2}$

$\bold{4x^2\left(6xy^2-y+21x^2\right)}$

➤ $\boxed{\bold{Mordancy}}$

Compare the slopes of the linear functions f(x) and g(x) and choose the answer that best describes them.

Tcecarenko [31]

Answer:

The slope of f(x) is equal to the slope of g(x).

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

step 1

Find the slope of the function f(x)

we have the points

(0,-1) and (3,1)

substitute in the formula

$m=\frac{1+1}{3-0}$

$m_1=\frac{2}{3}$

step 2

Find the slope of the function g(x)

take two points of the given table

(0,2) and (3,4)

substitute in the formula

$m=\frac{4-2}{3-0}$

$m_2=\frac{2}{3}$

step 3

Compare the slopes

$m_1=m_2$

therefore

The slope of f(x) is equal to the slope of g(x).

If the divisor is 40 what is the least three-digit dividend tag would give a remainder of 4

fgiga [73]

Let the three digit dividend be abc ,

then abc = 40*Q+4

So, abc is "40 times Q (the quotient, a number) plus 4"

we try a few values of Q for which 40Q+4 is a 3 digit number:

for Q=2

40*2+4=80+4=84

for Q=3

40*3+4=120+4=124

Answer: 124
