5×6 is 30, so it has to be 20+10.

5×6=20+10

Your answer is 10.

**Answer:**

**Step-by-step explanation:**

If theses are the edges of a prism then

Surface area = 2(5*7 + 5*3 + 7*3)

= 2 * 71

= 142 in^2.

First off, you can rewrite your equation like so: c=(a-b)x. You can then plug in your given constraints for your choices. If a-b = 1 and c = 0 leaving: 0=1(x), x must equal 0 and only 0 as any constant multiplied by 0 equals 0. So that choice is eliminated. Now let's consider when a=b and c != 0. Since we are given a-b and a=b and c != 0, we have:

c = 0x. This contradicts our claim we made about our constraints. C cannot equal zero but we have a-b=0. Therefore, this claim makes no sense as any value for x will not satisfy the equation. This choice is valid. When a=b and c=0, we have: 0 = 0x. Here, x can be any value and still return 0 as an answer. This choice is valid. If a-b=1 and c != 1, we have: c = 1x. Our only rule here is that c cannot equal 1. This means that x can be any value other than 1 so this choice can be marked down. If a != b and c=0, this gives: 0 = (a-b)x. Given that a-b can be any value, x must be equal to only 0 to satisfy this equation so this choice can't be correct. So the right answers are: option 2, option 3, option 4 and option 5.

Answer:

(-10,-7)

Step-by-step explanation:

the given equations: y=-3 and x=-10

we can substitute the x in the first equation as -10.

y=(2/5×-10)-3

simplify

y=(2/1*-2)-3

y=-4-3

y=-7

the y value is -7

we actually have the x value given as -10 (in the system)

So the answer is (-10,-7)

Hope this helps!

**Answer:**

- C = 100p +400
- y-intercept: 400
- the fixed cost for ...

**Step-by-step explanation:**

The graph shows C = **400** when p = 0 (at the left edge). This is the **y-intercept** value, and is the cost of production when no phones are produced. It is essentially the **fixed cost of rent and equipment**.

When p=1, the graph shows C = 500. That is, the cost goes up by 100 when p goes up by 1. This is the cost per phone. It shows up in the cost equation as the slope. So, the cost equation is ...

**C = 400 +100p**
