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.
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.
Answer:
-40
Step-by-step explanation:
f(5)= -(5)^2-3(5)
-25-15=-40
Zero, distributive, commutive. thats all I can think of.
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.
