What is the 100th term in the sequence 15, 22, 29, 36, 43,...

9. Simplify the expression. 4x + 7y - 2 + 6y + 6y - 8x - 5 Your answer

Answer:

9. -4x+19y-7

10. 7x+20

Step-by-step explanation:

9. To simplify this expression, simply combine like terms. Add all of the terms with the x variable together, then the terms with the y variable, then the constant terms. I will show this step by step, but usually you do not have to show this work. The order of the terms does not matter.

x variable terms: (4x-8x)+7y-2+6y+6y-5= -4x+7y-2+6y+6y-5

y variable terms: (7y+6y+6y)-4x-2-5=19y-4x-2-5

constant terms: (-2-5)-4x+19y=-4x+19y-7

10. To simplify this expression, expand all terms and then combine like terms. The first term can be expanded by multiplying each term in the parentheses by 2.

Expand terms: 2(5+3x)+(x+10)= 10+6x+x+10

Now, you can combine like terms as done on the last problem. Note that I got rid of the parentheses in the second term, as they did not matter (since there was no term in front of them).

x variable terms: (6x+x)+10+10=7x+10+10

constant terms: (10+10)+7x=7x+20

-.At a fair hamburgers sell for $3.00 each and hot dogs sell for $1.50 each. The equation 3x + 1.5y = 30 describes the number of

NikAS [45]

Answer:

Part a) The y-intercept is the point (0,20) and the x-intercept is the point (10,0)

The graph in the attached figure

Part b) See the procedure

Step-by-step explanation:

The questions are

Part a) Find the intercepts and graph the function

Part b) What does each intercept represent?

Part a) Find the intercepts and graph the function

Let

x-----> the number of hamburgers

y ----> the number of hot dogs

we have

$3x+1.5y=30$

Remember that

The y-intercept is the value of y when the value of x is equal to zero

so

For x=0

$3(0)+1.5y=30$

$1.5y=30$

$y=20\ hot\ dogs$

The y-intercept is the point (0,20)

The x-intercept is the value of x when the value of y is equal to zero

so

For y=0

$3x+1.5(0)=30$

$3x=30$

$x=10\ hamburgers$

The x-intercept is the point (10,0)

Plot the intercepts and graph the line

see the attached figure

Part b) What does each intercept represent?

The x-intercept is the number of hamburgers they can buy if they buy no hot dogs

The y-intercept is the number of hot dogs they can buy if they buy no hamburgers

Answer:

2-x^2+x^3

Step-by-step explanation:

The expression 2-x^2+x^3 can't be simplified further since the terms in the expression are unlike terms.

Hope this helps ;) ❤❤❤

8g-f when g is-1 and f is 4

Maksim231197 [3]

8g - f
First fill in the information.
8 x -1 minus 4
8 x -1 is -8
then you take -8 and subtract 4 from it.
So your final answer is -12. Hope this helped.
