Y = 5x + 4

Luda [366]

Answer:

Correct (1,9), (2,14)

Incorrect (1,8),(2,13)

Step-by-step explanation:

It is simple.

To find the correct values plug a x value.

For Example;

X=1

y=5(1)+4

y=5+4

y=9

so your X value is 1 and your Y value is 9

To solve for the incorrect values

Find the correct values and subtract 1 form the Y value.

A total of h males and (h - 2) females visit the museum on a certain day. If total of visitors for that day is 80, what is the v

Akimi4 [234]

Given:

Number of males = h

Number of females = (h-2)

Total number of visitors = 80

To find:

The value of h.

Solution:

We have,

Number of males = h

Number of females = (h-2)

So, the total number of visitors is:

$Total=h+(h-2)$

$Total=2h-2$

It is given that the total number of visitors is 80. So,

$2h-2=80$

$2h=80+2$

$2h=82$

Divide both sides by 2.

$h=\dfrac{82}{2}$

$h=41$

Therefore, the correct option is D.
