Simplify (-4x²+3x - 5) + (2x² +6x+7)​

Answers

Answer 1
since they are being added, we can drop the parentheses

-4x^2 + 3x -5 + 2x^2 + 6x + 7

now just combine like-terms

the final answer is: -2x^2 + 9x + 2

What is Distributive property?

It means to divide something. when a same number a multiplied with sum or subtraction of any numbers than we can divide that or distribute that.

For example: (a+b)*(c+d) = (a+b)*c+(a+b)*d

What is the mistake?

While distributing (X-2)(3X) + (X-2)(4) sign remains the same Whereas she changed the sign form - to + which is incorrect.

How to solve?

(X-2)(3x) + (X-2)(4)

(x)(3x) + (-2)(3x) + (x)(4) + (-2)(4)

Laila purchased a prepaid phone card for $25 . Long distance calls cost 24 cents a minute using this card. Laila used her card only once to make a long distance call. If the remaining credit on her card is $13.72 , how many minutes did her call last?

Answers

Answer:

The call lasted for 47 minutes.

Step-by-step explanation:

It is given that:

Value of prepaid card = $25

Cost per minute of long distance call = 24 cents = $0.24

Remaining credit = $13.72

Let,

x be the number of minutes

y be the remaining amount

y = 25 - 0.24x

13.72 = 25 - 0.24x

0.24x = 25 - 13.72

0.24x = 11.28

Dividing both sides by 0.24

[tex]\frac{0.24x}{0.24}=\frac{11.28}{0.24}\\x=47[/tex]

Therefore,

The call lasted for 47 minutes.

so i’m not sure if there is a different way to do this but here’s how i did it:

start with 2:5

then just keep going up till you can add both numbers and get 28

so next i multiplied both sides by 2 to keep the ratio and got 4:10

then i went back and tried again and tried multiplying 3

which is 6:15.

that only is 21 students so it’s not right

next i tried 4

2 x 4 = 8

and

5 x 4 = 20

8:20 is still a 2:5 ratio and

8 + 20 = 28

so 8 students were in the teachers play

let me know if i can clarify anything

Answer:

circley-axis5 units

Step-by-step explanation:

It can be helpful to actually see the graph. For 0 ≤ θ ≤ π, a circle is developed above the x-axis, symmetrical about the y-axis (θ=π/2). For π ≤ θ ≤ 2π, the same circle is traced again in the same direction (CCW), as values of r are negative for those angles.

The circle has a radius of 2.5, centered at (0, 2.5), so the diameter is 5 units. The length of the diameter is the farthest distance between any two points on a circle.
