2x+5x=100 x intercept​

Mathematics

Papessa [141]3 years ago

This is an equation involving x alone, so the most you can do is solve it:

2x+5x=100x \iff 7x=100x \iff 0=93x \iff x=0

How many different 4 digit numbers are there that are only made up of even digits
malfutka [58]
In a four-digit number, the first digit cannot be 0, so there are only 4 even numbers available. For the second, third, and fourth digits, there are 5 available numbers. Thus, the number of 4-digit numbers containing only even digits is 4 x 5 x 5 x 5 = 500 numbers.

What are the zeros of the polynomial function f(x)=x^2+5x+6
Molodets [167]
Find 2 numbers that multiply to 6 and add to 5.

3*2 = 6
3+2 = 5

x^2 + 5x+6 = (x+3)(x+2) = 0

Set each factor equal to zero.
x+3 = 0   ---->  x = -3
x+2 = 0 ----->  x = -2

Answer:
There are two zeros at -2 and -3.

Caleb is making a soil mix that is 8 parts dirt to 3 parts peat moss. Which of the following best describes the amount of dirt h
Ierofanga [76]

Answer:

D. He should add between 2 cups and 3 cups of dirt.

Step-by-step explanation:

First we need to take the ratio of dirt to peat moss.

8 parts dirt : 3 parts peat moss.

Now we take the ratio and find the value of dirt.

8 : 3 = \dfrac{8}{3}

x : 1 = \dfrac{x}{1}

\dfrac{x}{1} = \dfrac{8}{3}

We now multiply both sides by 1.

1\dfrac{x}{1} = 1\dfrac{8}{3}

x = \dfrac{8}{3}

x = 2.67

So now we substitute x.

2.67 Cups Dirt : 1 Cup Peat Moss
