​​​​​​Write an equation to describe this situation using decimals. “Tessa bought x pounds of almonds. Lark (y) bought more than
kvasek [131]

Answer:

y = 1.6x

Step-by-step explanation:

y is the total amount/pounds of almonds that Lark bought. x is the amount that Tessa bought. 3/5 is the same as 0.6. If we multiplied Tessa's amount by 0.6 it would decrease by 2/5 so we have to add 1 to make it 1.6. To find how much Lark bought multiply 1.6 and Tessa's amount.

Write the equation of the line that is per to x = -3 and passes through the point (4,-7)
Anon25 [30]

Answer:

y=-1/3x-17/3

Step-by-step explanation:

I assume you mean <em>perpendicular</em><em> </em>to x=-3.

In that case, we would flip and take the negative. A perpendicular slope would be x=-1/3

Now we plug the point (4,-7) into the equation

y=mx+b

y=-1/3x+b

-7=-1/3*4+b

-7=-4/3+b

b= -17/3

The whole equation would be:

y=-1/3x-17/3

<em>I hope this helps! :)</em>
