Answer:

The answer would be A. (1, -2)

Step-by-step explanation:

I made a graph, the rise is y, which is 2, when it is just one number and not a fraction you put a 1 on the bottom, so it would be 2/1, that is the slope. -4 is the y intercept, so you start at (0, -4) on the graph and go forward 1, and up 2. keep doing that and put dots as you go. One of the dots will be at (1,-2).

8 less than the product 8 and -4
sesenic [268]

Answer: The answer should be -40.

Step-by-step explanation: A product is the result of multiplication and in cases like this, "less than" points to the mathematical operation of subtraction.

So when you see product, you automatically know the problem deals with <em>multiplication</em>. When you see less than, you automatically know the problem deals with <em>subtraction</em>.

The translation of this problem is 8 · -4 = x, then x - 8 = a (aka the answer).

First step is to find x, then to find a.

Note that a positive times a negative will give you negative. 8 times 4 is 32, but since 4 is a negative number here, the answer would be -32.

From this we can conclude that x is -32.

8 · -4 = -32, then -32 - 8 = a

Final step is to find a, which would be the result of -32 - 8.

-32 - 8 is -40 (Note: a negative minus a positive is basically addition in negatives. For instance, if we did -2 - 2, it'll give us -4.).

a = -40

Your answer is -40.

Braden and Jason, who are florists, purchased flower bouquets and vases at the same store. Braden bought 3 flower bouquets and 5
Sergeeva-Olga [200]
The price of a flower bouquet is $2.75 according to the information on the question above. This problem can be solved using two linear equations with two different variables based on the transaction. The first equation is 3x +5y= 25.75 and the second equation is 8x+2y=29 which can be simplified as y=14.5-4x. You can find the x by substituting the "y" variable on the first with the second equation resulting in "x =2.75" which is the price of the flower bouquet<span>.</span>
