Answer:

Step-by-step explanation:

Cost of 4 oranges = $x

cost of 1 orange= x/4

Cost of 10 oranges = x/4*10 = $ 2.5x

Cost of a custard apple = $1.25

Cost of n custard apple = 1.25*n = 1.25n

Cost of 4 bananas = $3

Cost of a banana = 3/4 = $0.75

Cost of (3n +1) bananas = 0.75*(3n+1)  = 0.75* 3n + 0.75*1 = 2.25n  + 0.75

Cost of fruits = 2.5x + 1.25 n + 2.25n + 0.75

                      = 2.5x + 3.50n +0.75

Solve the equation a = m – n for the variable n.
Rzqust [24]

Step-by-step explanation:

Get n by itself. It doesn't matter how you do it, you'll get the same answer whether you subtract m or add n to the other side. You just need to have a positive n by itself on one side of the equation.

a=m-n\\n+a=m\\n=m-a

Answer:

B. n=m-a

Both are correct, because when they divide their pencils that way, both of them will have equal amount of boxes and equal amount of pencils in each box.

A local pizza restaurant delivery time has a uniform distribution over 0 to 60 minutes. What is the probability that the pizza d
Likurg_2 [28]

Answer:

X \sim Unif (a= 0, b=60)

And we want to find the following probability:

P(X>30)

And for this case we can use the cumulative distribution given by:

F(x) =\frac{x-a}{b-a}, a \leq x \leq b

And for this case if we use this formula and the complement rule we have:

P(X>30)= 1-P(X

Step-by-step explanation:

Let X the random variable who represent the pizza delivery time and we know that the distribution for x is given by:

X \sim Unif (a= 0, b=60)

And we want to find the following probability:

P(X>30)

And for this case we can use the cumulative distribution given by:

F(x) =\frac{x-a}{b-a}, a \leq x \leq b

And for this case if we use this formula and the complement rule we have:

P(X>30)= 1-P(X

Question 9 (5 points)
Sunny_sXe [5.5K]

to get the equation of any straight line, we simply need two points off of it, let's use those two points from the table in the picture below.

(\stackrel{x_1}{-4}~,~\stackrel{y_1}{13})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{-17}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-17}-\stackrel{y1}{13}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{(-4)}}} \implies \cfrac{-30}{6 +4} \implies \cfrac{ -30 }{ 10 }\implies -3

\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{13}=\stackrel{m}{-3}(x-\stackrel{x_1}{(-4)}) \\\\\\ y-13=-3(x+4)\implies y-13=-3x-12\implies y=-3x+1

PLEASE ANSWER
charle [14.2K]

Answer:

The slope intercept form is y=\frac{1}{2}x-5

Step-by-step explanation:

Given : Equation y+3=\frac{1}{2}(x-4)

To find : Rewrite the equation in slope-intercept form ?

Solution :

The slope-intercept form is y=mx+c

Equation y+3=\frac{1}{2}(x-4)

y+3=\frac{1}{2}x-\frac{1}{2}\times 4

y+3=\frac{1}{2}x-2

y=\frac{1}{2}x-2-3

y=\frac{1}{2}x-5

Therefore, the slope intercept form is y=\frac{1}{2}x-5
