Identify all properties being shown: (5x^3 + 2) + 7x^2 = (7x^2 + 5x^3) + 2

Answers

Answer 1

Answer:

No solutions

Step-by-step explanation:

5x^3 + 2 + 7x^2 = 7x^2 + 5x^3 +2

125x + 2 + 49x = 49x + 125x + 2

-125x                             -125x

2 + 49x = 49x + 2

-2 -49x    -49x  -2

0 = 0

What is the y-intercept of the line that models this situation?

Answers

Since the slope is consistent the y intercept would be 70.

You can try drawing a line connecting the other dots and see what crosses the y intercept.

But if you want to do the actual math the formula is y=mx+b. B being the y intercept.

So find slope (rise over run) or (y2-y1)/(x2-x1) I’ll choose (1, 65) (2, 60)
m= 60-65/2-1= -5/1= -5.
Negative also means the line is sloped down.

Plug the slope back into the formula using one of the points to substitute.

Using (1,65) into y=mx+b
65=-5(1)+b
65 =-5+b
65+5=b
b= y-intercept= 70

2m:80cm.Give answer in lowest term PLEASE ​

Answers

Answer:

5:2

Step-by-step explanation:

In centimetres

convert 2 m to cm which will be 200 cm

then simplify 200 cm:80 cm --> 5:2

(we cancelled out the zero --> 20:8 then divide 20/2= 10 and 8/2= 4

again the same --> 10/2= 5 and 4/2= 2.

5 and 2 are prime numbers which have no other factor except for 1 and themselves so it cannot be simplified further.

Therefore your answer is 5:2

In metres

convert 80 cm to m which will be 0.8 m

the same steps: simplify 2:0.8

to remove the decimal move the decimal place one to the right --> 8

so you also have to move the decimal place to the right for the numerator: 20

20/8 = 5/2

Solve for P
5/6p + 1= 3/4p -4

Answers

hii so p is equal to -60

Answer: P= -60

Step-by-step explanation:

5/6p +1=3/4p -4

5/6p=3/4p-4.       Subtract 1 from both sides

5p=9/2p-30.        Trick( if there is a fraction multiply the denominator on both sides to make it a non fraction so life is easier, as I did I first multiply by 6)

10p=9p-60.           multiply the second denominator on both sides(multiple by 2)

P=-60.                     Subtract 9p on both sides and keep the sign and you’ll get -60

A shirt that you want to buy costs $15.50. You can use a $5 discount coupon if you spend at
least $20. Solve an inequality that represents how much more you must spend to use the $5
coupon.
(1 Point)

Answers

Answer: The answer is m= ≥4.50

The required inequality is m ≥ 4.50

What is inequality?

A relationship between two expressions or values that are not equal to each other is called inequality.

Given that, A shirt that you want to buy costs $15.50. You can use a $5 discount coupon if you spend at least $20.

Cost of the shirt = $15.50

you can use a $5 discount coupon if you spend at least $20

The question requires you to find how much more you need to spend to be able to use the $5 discount coupon

The shirt already cost $15.50

Total amount you need to spend = $20

Let the amount remaining = m

m ≥ $20 - 15.50

m ≥ $4.50

Hence, you need to spend $4.50 in order to be able to use the $5 discount coupon.
