This called the distributive property.

The distributive property states that a(b + c) = ab + ac

6x + y = -2
y = -3x + 1

Substitute the value of y in first equation,
6x -3x + 1 = -2
3x = -2-1
x = -3/3
x = -1

Now, Substitute it in 2nd equation,
y = -3(-1) + 1
y = 3+ 1 = 4

Coordinates would be: (-1,4) Mark that point and join with origin.

Hope this helps!

Kenji's town voted on a new speed limit. Of the votes received, 39 were in favor of the new speed limit and 13 were opposed. Wha

Nata [24]

Answer:

75%

Step-by-step explanation:

You need to find the total number of votes first. Just add 13 and 39 which would equal 52.

Then divide the number of people in favour by the total number of voters and multiply by a 100 to find the percentage.

39 + 13 = 52

39/52 = 0.75

0.75 x 100 = 75.0

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of

Tema [17]

Answer:

Small box weighs 13.75 kg & large box weighs 15.75 kg

Step-by-step explanation:

We can write 2 simultaneous equation and solve for weight of each box.

<em>Let weight of large box be l and small box be s.</em>

<em />

"<u>3 large boxes and 5 small boxes has a total weight of 116 kilograms</u>":

$3l+5s=116$

and

"<u>9 large boxes and 7 small boxes has a total weight of 238 kilograms</u>":

$9l+7s=238$

<em>Now we can solve for l in the 1st equation and put it into 2nd equation and get s:</em>

<em> $3l+5s=116\\3l=116-5s\\l=\frac{116-5s}{3}$ </em>

<em>now,</em>

<em> $9l+7s=238\\9(\frac{116-5s}{3})+7s=238\\3(116-5s)+7s=238\\348-15s+7s=238\\348-238=15s-7s\\110=8s\\s=\frac{110}{8}=13.75$ </em>

<em />

<em>now we plug in 13.75 into s into equation of l to find s:</em>

<em> $l=\frac{116-5s}{3}\\l=\frac{116-5(13.75)}{3}\\l=15.75$ </em>
