Answer:

2x + 5y = -15  OR 2x + 5y + 15 = 0  Not sure they want it equal to zero

Step-by-step explanation:

y + 7 = -2/5(x - 10)

y + 7 = -2/5 x + 4

2/5x + y =-3

5(2/5 x + y = - 3)

2x + 5y = - 15

OR

2x + 5y + 15 = 0

In order to find it, we should divide 12 by 4:-

3

Now, solve our word problem:-

Matthew bought 12 roses. \sf{\displaystyle\frac{1}{4} } of these roses were white.

And we already know how to solve this problem :)

Hence,

\bigstar{\boxed{\pmb{3~of~the~roses~were~white}}}

Evaluate the expression if m = 3.<br><br> 3m^2<br><br><br> (SHOW YOUR WORK)
iragen [17]

The value of given expression when m = 3 is 27

<h3><u>Solution:</u></h3>

Given expression is 3m^2

We have to evaluate the given expression for m = 3

To find for m is equal to 3, substitute m = 3 in given expression

From given expression,

\rightarrow 3m^2

Plug in m = 3 in above expression

\rightarrow 3(3)^2 ------ eqn 1

We know that,

a^2 can be expanded as,

a^2=a \times a

Applying this in eqn 1, we get

\rightarrow 3(3)^2=3 \times (3 \times 3)

Simplify the above expression

\rightarrow 3(3)^2=3 \times (3 \times 3) = 3 \times 9 = 27

Therefore, for m = 3 we get,

\rightarrow 3(3)^2=27

Thus value of given expression when m = 3 is found
