7 0

Answer:

x=11 (read below)

Step-by-step explanation:

7 + x = 18

Subtract 7 from both sides

x=11

It's quite simple because if you do something to one side of the equation, you need to do it to the other because otherwise the equation won't be equal. This is how you need to simplify most problems, by taking something from one side and taking from the other as well.

Write a quadratic function f whose zeros are 3 and 12. f(x) = ?

ololo11 [35]

Answer:

The above equation is a quadratic function whose zeroes are 3 and 12.

Step-by-step explanation:

The general quadratic equation is given by :

$ax^2+bx+c=0$

It is given that, the zeroes of a quadratic function are 3 and 12. It means they must be factors of it such that,

$(x-3)=0\\\\(x-12)=0$

So, we can write as :

$(x-3)(x-12)=0$

Multiplying both factors,

$(x-3)(x-12)=0\\\\x^2-12x-3x+36=0\\\\x^2-15x+36=0$

So, the above equation is a quadratic function whose zeroes are 3 and 12.

How many solutions does this equation have

leva [86]

The best way to solve this equation is to simplify it. So first you’ll distribute the -2 on the left side. This will give you the equation -2t+8=10-2t. Now you bring t to one side by adding 2t to both sides. You will find that t cancels out and you are left with 8=10. Since this statement isn’t true there are no solutions to this equation.

Write two integers whose products is negative?

yKpoI14uk [10]

Answer:

Any negative integer and any positive integer.

Like -5 and 3.

Step-by-step explanation:

In multiplication, a positive number and a negative number will result in a negative product.

So, you can use any positive integer and multiply it by any negative integer to get a negative product.

Using the integers I gave:

$-5*3 = -15$

Answer: 6 hours or 360 minutes

Step-by-step explanation:

First find out how long it takes to deliver to one house.

Convert hours to minutes.

2.5 x 60 = 150 minutes total

Divide to find the time per house

150 minutes / 130 houses = 1.15 minutes per house

Now multiply this rate by the number of houses (312).

312 x 1.15 = 360 minutes

If you want it in hours then divide by 60.

360/60 = 6 hours.
