How to solve 3(x+1)=5(x-2)+7

igor_vitrenko [27]

So first do 3(x+1) which is 3x+3 because you have to multiply the outside number by the stuff in side the parentheses. Then you do the 5(x-2)+7 and it should be 5x-10+7 so now your equation should be 3x+3=5x-10+7 now subtract the 3x from the 5x and now your equation should look like this: 3=2x-10+7. Then you add the 10 and the 7 so now your equation should look like this: 3=2x-3 because it's a -10 and a positive 7 it would be -3. So then you have to add the -3( which now becomes positive to the other 3 in front of the = sign. So now your equation should look like this: 6=2x. Now divide by 2 to get x by its self and now your answer should be 3=x or x=3.

8. Graph the following equation: y = x2 + 4x - 5

Dennis_Churaev [7]

Answer:

Given: y = x2 + 4x – 5

Find the following

y-intercept

x-intercepts or the zeros of the functions or roots

graph of the function, given vertex is at (-2, -9)

Solve the system of linear equations – x + 6y = 8 2x + 5y = 3

Write the names of curves, given their equations:

x2/16 + y2/9 = 1

3y = 2x + 5

(x - 5)2 + (y + 6)2 = 25

x2/16 – y2/25 = 1

y = 2x2 + 10x + 25

It cost $20 a day to rent a bike. create an equation using c (cost) and d(days)

BlackZzzverrR [31]

Answer:

$20d = c

Step-by-step explanation:

Since the cost is $20 per day, $20d ($20 for how many days) would be the start of the equation.

C = cost, and $20d will determine the cost, so $20d = c

is your final answer/equation.

Cheers!
