Show work<br><br> Simplify this expression by combining the like terms<br><br> 7y + 10 + 3y - 4 - 6y
eimsori [14]
In this problem “like terms” has two groups: one with a number and y, and one with just numbers. First I’ll rewrite the equation with the terms in a different order, grouped with like terms. Then we’ll do the math for them:

7y + 10 + 3y - 4 - 6y

= 7y + 3y - 6y + 10 - 4

= 10y - 6y + 6

= 4y + 6

Let me know if you have questions on this.

Y= -7x-2<br> y+ 3 = -7x + 1<br> (<br> 2,3)<br> no solution<br> an infinite number of solutions
Naya [18.7K]

Answer:

Infinite number of solutions.

Step-by-step explanation:

y = -7x - 2

y + 3 = -7x + 1

Subtract 3 from both sides:

y = -7x - 2

- this is the same as the first equation.

We can put any number of valid combinations of x and y into this equation.

So there are infinite solutions.

Analyze Relationships A scale for a scale drawing is 10 cm:1mm. Which is larger, the actual object or the scale drawing: Explain
sleet_krkn [62]
If you're saying that the scale is 10 cm: 1 mm then the scale will be larger than the actual object because for every 1 mm of the object it will equal 10 cm of the scale drawing.
