Answer:

No, the answer is (-3/7, -33/7)

Step-by-step explanation:

y=-3x-6 can be rewritten as y+3x=-6

so, our two equations are:

1. y+3x=-6

2. 3y+2x=-15

we can multiply the first equation by 3.

1-1.3y+9x=-18

Now we can subtract the second equation from equation 1-1.

3y+9x=-18

<u>-(3y+2x=-15)</u>

7x=-3

x=-3/7

Now that we have x, let's plug it into an equation. I will plug it into the first equation.

y=-3(-3/7) - 6

y=9/7 - 6

y=-33/7

so the points are (-3/7, -33/7)

(-3/7, -4 5/7)


it tells u what y is so plug that in to the second equation which would give you 2x+3(-3x-6)=-15. simplify that which would give you 2x-9x-18=-15. simplify again which would give u -7x=3. then solve for x which is -3/7. than plug -3/7 in as x which gives you y=-3(-3/7)-6. simplify that which gives you 9/7-6 which equals -4 5/7.

(a) The area of a rectangular parking lot is 7050 m².
Nastasia [14]

Answer:

75 m, 96 m

Step-by-step explanation:

a. Area = length x width

7050 = 94 x width

7050/94 = w

75 m is width

b. perimeter = 2L + 2W

356 = 2L + 2(82)

356 = 2L + 164

192 = 2L

96 m = L

The table shows the number of each type of toy in the store. the toys will be placed on shelves so that each shelf has the same
skelet666 [1.2K]
First, we compute the highest common factor between the numbers of toys. The highest common factor for 45, 105 and 75 is 15. Therefore, we will need 15 shelves. On each shelf, there will be 45/15 = 3 dolls, 105/15 = 7 footballs and 75/15 = 5 small cars
