Answer:

y = - 7x + 4

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 = - 7 and c = 4, thus

y = - 7x + 4 ← equation of line

Answer:

Step-by-step explanation:

y = mx + c

Where m is the slope = -7

C is the intercept = 4

: y = -7(x) + 4

y = -7x + 4 the equation of the line

A crew of loggers cleared ½ acre of lumber in 4 days. How long will it take the same crew to clear 2 ¾ acres of lumber?
Tanzania [10]
You can use a proportion

1/2(acres)       2(3/4)acres
--------------  =   --------------
4(days)              x(days)

4*2(3/4) = 6
6/(1/2) = 12

It would take 12 days.

Max correctly solved this inequality.
pentagon [3]

Answer:

Answer:

See the graph attached. The red arrow represents the shaded area.

Explanation:

The inequality and its solution are given:

     

The solution set is all real numbers less than or equal to -50.

In a number line, the values less than -50 are all the values that are to the left of -50. Thus, the graph of a ≤ -50 must include -50 and the region to the left of it.

To indicate that - 50 is included, draw a solid point; then, shade the region since it to its left.

Please, see the graph attached. The red arrow represents the shaded area.

A fitness center is interested in the average amount of time a client exercises in the center each week. Define the following in
Lubov Fominskaja [6]

Answer: C

Step-by-step explanation: As they are interested in the amount of time a client exercises in a week, the population would be all the clients that use the fitness center for a given week.

Clients that do not go on this week are not part of the population. The amount of time is what they want to know, so it cannot be the population.

Find the coordinates of the point 7/10 of the way from A to B
OverLord2011 [107]

Answer:

  (6.8, 1.3)

Step-by-step explanation:

<u>Given</u>:

  A(-3, -5), B(11, 4)

<u>Find</u>:

  P such that AP/AB = 7/10

<u>Solution</u>:

Using the desired relation, we have ...

  (P -A)/(B -A) = 7/10

  10(P -A) = 7(B -A) . . . . . multiply by 10(B-A)

  10P = 7B +3A . . . . . . . . add 10A to both sides

  10P = 7(11, 4) +3(-3, -5) = (77 -9, 28 -15) = (68, 13)

  P = (68, 13)/10 = (6.8, 1.3)

The point 7/10 of the way from A to B is (6.8, 1.3).
