Answer:

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

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - \frac{1}{2}, thus

y = - \frac{1}{2} x + c ← is the partial equation

To find c substitute (8, 1) into the partial equation

1 = - 4 + c ⇒ c = 1 + 4 = 5

y = - \frac{1}{2} x + 5 ← in slope- intercept form

In a survey of 100 Phoenix high school students, 40 were
melomori [17]

Answer:

40 part-time male students were in the survey.

Step-by-step explanation:

Given:

Total number of  students in the Phoenix high school = 100

Number of female student = 40

Number of male student who went to  Phoenix  Full time = 20 students

Total number of  full time students = 50 students

To Find:

Number of part time male students in the survey = ?

Solution:

we know that the total number of students  = 100

Now total number of male students  = total number of students - total number of female student

Now total number of male students  = 100 - 40 =  60 students

Now among these 60 students, 20 males went to Phoenix

Full time

So the remaining male students = 60-20 =40 students

Hence these 40 students are part-time male students

What is 16divided by 3,48216) 3,482
Basile [38]

Answer:

15,999264824

Step-by-step explanation:

According to the Order of Operations [GEMS\BOMDAS\PEMDAS etc.], Division and Multiplication are done from left to right as you see it, so first, you divide 16 by 3,48216, which is 4,5948491741, then you multiply that by 3,482 to get 15,999264824.

Has an x-intercept of (4,0) and a y- intercept of (0,-2)
Mazyrski [523]

Just to be different we'll start with intercept intercept form which says the line through x intercept (a,0) and y intercept (0,b) is

\dfrac x a + \dfrac y b = 1

Through (4,0) and (0,-2) that's

\dfrac{x}{4} + \dfrac{y}{-2} = 1

Multiply through by the common denominator of 4 for standard form:

x - 2y = 4

For slope intercept form we solve for y

-2 y = -x + 4

y = (1/2) x - 2

We see our slope is (1/2) and we go through (4,0) so point slope form is

y - 0 = (1/2)(x - 4)

y = (1/2)(x-4)

42/4 as a whole or mixed number and in simplified form
AlekseyPX

Answer:

10.5

Step-by-step explanation:

42/4 can be reduced by dividing numerator and denominator by 2:  21/2.

This is an improper fraction.  One way to obtain the equivalent mixed number would be to multiply numerator and denominator of 21/2 by 5, obtaining 105/10, which reuces to 10.5.

We could also divide 42 by 4 in the usual way, obtaining 10.5.
