Please help me Create a system of two equations but do not solve the system please actually help me please and thank you

Answer:

7r + g = 46

7r + 2g = 50

Step-by-step explanation:

Hi there!

Matt and Trevon both bought supplies from a store, and we know that Matt bought 7 rose bushes and 1 geranium, and spent a total of $46 while Trevon bought 7 rose bushes and 2 geraniums, and spent a total of $50

We know that each rose bush costs a certain amount, and each geranium must cost a certain amount, but we don't know what that amount is; it's also possible that the amounts could be different

So let's say that the cost of one rose bush is r dollars; for Matt, that means that he spent 7r dollars on 7 rose bushes. Trevon also bought 7 rose bushes, meaning he also spent 7r dollars on rose bushes.

Since the cost of the geraniums can be different from the cost of every rose bush, let's express it with a different variable, like g.
Since Matt bought one geranium, he spent g dollars on that one geranium.
Trevon bought 2 geraniums, so he spent 2g dollars on the geraniums

The total cost of what Matt spent on flowers was 7r + g dollars (7 rose bushes + 1 geranium), which is equal to 46 dollars

As an equation, that can be written as 7r + g = 46

Trevon spent 7r + 2g dollars (7 rose bushes + 2 geraniums), which gave him a total of $50

As an equation, that can be written as 7r + 2g = 50
The two equations therefore are:
7r + g =46
7r+2g=50
Hope this helps!

Can anyone help me in explaining subtraction of polynomials please help I’m desperate and I’m pretty much on my own when it come

Answer:

Think of combining like terms when subtracting polynomials. For example, 3x² and -2x². They both have x² in common. So, if you were to combine 3x² and -2x², it would be like 3x² + (-2x²). Think of this like 3 + (-2), which equals 1. In this case, it would equal 1x² or x².

Let's take this problem for example: 6x² - 3x + 4 - (-2x² +2x - 2)

Parentheses are super important; The first thing you want to do is distribute the negative sign out to everything inside the parentheses!

So,

6x² - 3x + 4 - (-2x² +2x - 2) *multiply the neg. to -2x², 2x, and -2

Now, if you do that, the equation would now look like:

6x² - 3x + 4 + 2x² - 2x + 2

Now think of combining like terms. Here are the like terms:

6x² - 3x + 4 + 2x² - 2x + 2 (Let's rewrite it to look like this...)

6x² + 2x² - 3x - 2x + 4 + 2

Let's combine the x²'s first, so... 6x² + 2x² = 8x²

Let's combine the x's, so... -3x - 2x = -5x

Let's combine the constants (numbers with no variable), so... 4 + 2 = 6

Your solution should be 8x² - 5x + 6

To the nearest hundredth, what is the value of A(6)? (Use 3.14 for .)

ELEN [110]

I believe you multiply 1 by 6 because there is an invisible 1 infront of that a then you divide 3.14 to the 2 power And you might get your answer
