Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

m - slope b - y-intercept

Step-by-step explanation:

Step 1: Define

Standard Form:   3x - y = 7

Step 2: Rewrite

Find slope-intercept form

Subtract 3x on both sides:                    -y = 7 - 3xDivide -1 on both sides:                         y = 3x - 7

Answer:

y = 3x + 7

y = 3x - 3

y = -4x + 4

Step 2: Solve for x

Substitution

Substitute in y:                    3x - 3 = -4x + 4Isolate x terms:                    7x - 3 = 4Isolate x term:                     7x = 7Isolate x:                              x = 1

Here we see that our x-value would equal 1.

∴ (-3, 0) is NOT a solution to the systems.

A batch has 15000 coloured bulbs. 3/5 of the batch are orange in colour & the rest are green . if 1/8 th of the green bulbs are not working , how many green bulbs are functional?

Answers

Answer:

5250 bulbs are functional green bulbs

Step-by-step explanation:

find out how much 1/5 of 15000 is

15000/5=3000

find out how many are orange

3/5=1/5+1/5+1/5         3000*3=9000

of the 15000 bulbs 9000 are orange the rest are green find the amount that is left over

15000-9000=6000 bulbs are green

find out what 1/8 of the green bulbs is

6000/8=750

1/8 or 750 green bulbs are not working

find out how many bulbs are functional

6000-750=5250 bulbs are functional green bulbs

Consider the system of inequalities.
3x + 2y < 8
-5x - 9y > -2
Select all ordered pairs that are solutions to the system of inequalities.
(-10, -3)
a)
b)
(-1, 5)
(0, 0)
d)
(1, -1)

Answers

Answer:

 b)

The point is (-1,5) and (0,0) also satisfies the given inequalities

The solution of the given inequalities

(x, y) = (4 , -2 )

Step-by-step explanation:

Step(i):-

Given system of equations are

3x + 2y < 8

-5x - 9y > -2

The solution of the given equations are

3x + 2y = 8   multiply '5'

-5x - 9y = -2 multiply '3'

       15 x + 10 y = 40  ...(i)

       -15x - 27 y = -6.....(ii)

Adding (i) and (ii) , we get

          - 17 y = 34

                y = -2

Substitute y = -2 in equation 3x + 2y =8

          3x - 4 =8

             3x = 12

               x =4

The solution of the given system of inequalities

(x, y) = (4 , -2 )

Step(ii):-

                   3x + 2y < 8

                  -5x - 9y > -2

The point is (-1,5)

                 -3 + 10 < 8

                    7 < 8

                5 - 45 > -2

                   -40 > -2

The point (0,0) also satisfies the given inequalities

Final answer :-

The point is (-1,5) and (0,0) also satisfies the given inequalities

Jada traveled 135 miles in 3 hours. Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed. A) How far did Jada travel in 1 hour?

Answers

Given:

Jada traveled 135 miles in 3 hours.

Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed.

To find:

How far did Jada travel in 1 hour?

Solution:

We have,

Distance traveled by Jada in 3 hours = 135 miles

Then,

Distance traveled by Jada in 1 hour = [tex]\dfrac{135}{3}[/tex] miles

                                                           = 45 miles

Therefore, Jada travel 45 miles in 1 hour.

the cost for a bakery to make a dozen muffins is 2.52. the sale price of an individual muffin is 2.99. for one day, the bakery will donate 1/2 of the profits from muffin sales to charity. what is the bakeries donation, in dollars, if 88 muffins are sold that day

Answers

Answer:

I'm pretty sure it would be $131.56

Step-by-step explanation:

I think it will be $131.56 because if you take an multiply the 2.99 times  88 the number of muffins that were sold that day, then you would get $263.12. If you donated 1/2 of the profits made, then you would take 263.12 and divide it by 2 because half of it would be divided by 2. So therefore you would get $131.56! Hope this helps!
