Answer:

The slope is 3/2 and the y intercept is 4

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

2y -3x=8

Add 3x to each side

2y-3x+3x= 8+3x

2y = 3x+8

Divide by 2

2y/2 = 3/2x +8/2

y = 3/2x +4

The slope is 3/2 and the y intercept is 4

The function f(x) is shown on the graph. If f(x) = 0, what is x?

Radda [10]

Answer:

Step-by-step explanation:

note y = f(x) = 0

y = 0 is the x- axis

We are looking for values of x on the x- axis where the graph crosses/touches

This occurs at

x = - 2, x = 1, x = 3 → C

Membership to a national running club is shown in the table. Which answer describes the average rate of change from Year 3 to Ye

Nataly [62]

Answer:

Membership decreased by an average of 6,600 people per year from Year 3 to Year 5

Step-by-step explanation:

The average rate of change from Year 3 to Year 5 will be given by the slope of the line joining the points;

(3, 96.8) and (5, 83.6)

The slope of a line given two points is calculated as;

( change in y)/( change in x)

In this case y is the number of members for a given year x.

average rate of change = (83.6-96.8)/(5-3)

= -6.6

Since the number of members is given in thousands, we have;

-6,600

The negative sign implies a decrease in the number of members. Therefore, membership decreased by an average of 6,600 people per year from Year 3 to Year 5

Just one more What is 35 = 5 |x+6|-10

agasfer [191]

35 = 5|x + 6| - 10

First, add '10' to both sides.
$35 + 10 = 5|x + 6|$
Second, add 35 + 10.
$45 = 5|x + 6|$
Third, divide the sides by '5'.
$\frac{45}{5} = |x + 6|$
Fourth, since 9 × 5 = 45, simplify the fraction to 9.
$9 = |x + 6|$
Fifth, separate the equation into 2.
$9 = x + 6 \\ and \\ 9 = -(x + 6)$
Sixth, solve the first one.
( $1) 9 - 6 = x \\ 2) 3 = x \\ 3) x = 3$
Seventh, solve the second one.
$1) 9 = -x - 6 \\ 2) 9 + 6 = -x \\ 3) 15 = -x \\ 4) -15=x \\ 5) x = -15$
Eighth, gather both the solutions you just got.
$x = -15,3$

Answer: x = -15, 3
