Thanks for writing out the whole question, m=x is the correct answer. So B. Since the denominators are equal, the numerators must be too

Write an equation for the line shown on the graph.

Irina18 [472]

Answer:

$\large\boxed{y=\dfrac{2}{3}x+1}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

The fromual of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

(x₁, y₁), (x₂, y₂) - points on a line

We have the points from the graph:

(0, 1) → b = 1 and (3, 3).

Calculate the slope:

$m=\dfrac{3-1}{3-0}=\dfrac{2}{3}$

Finally we have the equation of a line:

$y=\dfrac{2}{3}x+1$

A survey is taken among customers of a fast-food restaurant to determine preference for Hamburger and Cheeseburger. Of 180 respo

stiv31 [10]

Using it's concept, it is found that the probabilities are given as follows:

a.1/2, 1/9, 5/9.

<h3>What is a probability?</h3>

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, 90 out of 180 individuals are children, hence the probability is given by:

p = 90/180 = 1/2.

Out of 90 adults, 60 - 50 = 10 preferred cheeseburgers, hence the probability is given by:

p = 10/90 = 1/9.

Of the 180 individuals, 90 are children, and 10 are adults who prefer cheeseburgers, hence the probability is given by:

p = 100/180 = 10/18 = 5/9.

Hence option a is correct.

Two numbers (represented by A and B) when multiplied together produce a maximum value. Two times the first number (A) plus one t

marusya05 [52]

Maximize $U=ab$ subject to $2a+b=48$

$b = 48-2a$

$U = ab = a(48-2a)$

$U = -2(a^2 - 24 a) =-2(a^2 - 24 a + 144) + 2(144) = -2(a-12)^2+288$

That's clearly maximum when the squared term is zero, so

$a=12$

$b=48-2(12) = 24$

$U=12(24)=288$

Answer: a=12, b=24, max 288

What value of a satisfies the following equation? -2(a + 3) = -4a + 32

Yanka [14]

Answer:

a = 19

Step-by-step explanation:

-2(a + 3) = -4a + 32

-2a - 6 = -4a +32

+2a +2a

-6 = -2a + 32

-32 -32

-38 = -2a

divide by -2

a = 19
