​

Answers

Answer:

(y + 6)(y - 4)

Step-by-step explanation:

Factor the following:

[tex] \longrightarrow [/tex] y² + 2y - 24

The factors of -24 that sum to 2 are 6 and -4.

So,

[tex] \longrightarrow [/tex] y² + (6 - 4)y -24

[tex] \longrightarrow [/tex] y² + 6y - 4y - 24

[tex] \longrightarrow [/tex] y(y + 6) - 4(y + 6)

[tex] \longrightarrow [/tex] (y + 6)(y - 4)

Answer:

( y-4) ( y+6)

Step-by-step explanation:

= y^2 + ( 6 - 4)y - 24

= y^2 + 6y - 4y - 24

= y( y + 6) - 4(y + 6)

= ( y - 4 ) ( y + 6)

Answers

Answer:

x = 12

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

5x + 18 = 7x - 6

Step 2: Solve for x

Subtract 5x on both sides:               18 = 2x - 6Add 6 to both sides:                         24 = 2xDivide both sides by 2:                     12 = xRewrite:                                              x = 12

Step 3: Check

Plug in x to verify it's a solution.

Substitute:                    5(12) + 18 = 7(12) - 6Multiply:                        60 + 18 = 84 - 6Add/Subtract:               78 = 78

And we have our final answer!

The cost of 3 pounds of grapes is $6.57. What is the constant of proportionality that relates the cost in dollars, y, to the number of pounds of grapes, x?

Answers

Answer:

$2.19

Step-by-step explanation:

Given that :

Cost of 3 pounds of grape = $6.57

Cost in dollars = y ; number of pounds = x

Cost in dollars α number of pounds

Cost in dollars = k * number of pounds

k = constant of proportionality

$6.57 = k * 3

$6.57 = 3k

Divide both sides by 3

6.57 / 3 = 3k/ 3

2.19 = k

k = $2.19

HELLO HUMANS! QUICK QUESTION. WILL MARK AS BRAINLIEST!
How do you solve for the slope of a graph that isn't straight? How would I solve the slope for this?

Answers

9514 1404 393

Answer:

  use the slope formula

Step-by-step explanation:

Usually, you are asked for an average slope over some interval. The slope is calculated on that interval the same as it would be if you were given two points, one at each end of the interval.

  m = (y2 -y1)/(x2 -x1)

For example, if you wanted to know the slope on the interval [1, 2] hours, the points you would use would be ...

  (hours, miles) = (1, 25) and (2, 75)

The corresponding slope on that interval is ...

  m = (75 -25)/(2 -1) = 50 . . . . miles per hour

__

You can identify four (4) regions on this graph in which the slope is constant:

  (0, 1) . . . slope is 25 mph

  (1, 2) . . . slope is 50 mph, as computed above

  (2, 3) . . . slope is 0 (the rider has stopped)

  (3, 5) . . . slope is 25 mph

Over different intervals, you need to identify the points involved and use the formula to compute the average slope.

and y, the number of pounds of each type of chocolate. write two equations and solve using elimination
!!!!PLEASE HELP!!!!

Answers

Answer:

5 pounds each

Step-by-step explanation:

Required equations:

x + y = 103.50x + 4.30y = 39

Substitute x in the second equation:

x = 10 - y

Solve for y:

3.5(10 - y) + 4.3y = 3935 - 3.5y + 4.3y = 390.8y = 4y = 4/0.8y = 5

Then

x = 10 - 5 = 5
