x-intercept (y=0)
-2x+5y=-10
Substitute now :
-2x+5(0)=-10
-2x=-10
Divide both numbers by -2
-2/-2x= -10/-2
x=5
x- intercept = (5,0)
Answer: the third choice
Answer:
22. 10^10
8 Billion has 9 zeros and 10 to the power 10 means there is a total of 10 zeros. So 10 zeros is more closer to 9 zeros than that of 11 zeros.
23.Exponential form is when a certain number is raised to the power of a certain number or also known as exponents. Exponents signifies that the base or the number that is being raised to a certain powers will be multiplied a number of times, based on the exponents.
Exponential form is defined as repeated multiplication of the base.
The process:
8/6 = 20/x
You would have to cross multiply first.
8 20 6×20= 120
6 x 8×x=8x
Then you rearrange the equation,
120=8x
And you divide by 8 ( because it has the variable next to it)
120÷8=15
So, x=15
To complete the table we must carefully observe the keypad, we will notice that each number is equivalent to 3 letters of the alphabet except the numbers 7 and 9 which have 4 letters each.
<h3>How does the keypad work?</h3>
Previously, cell phone keypad had a different layout than today. The numbers were related to the letters of the alphabet and the number key was pressed according to the letters that were related.
For example, if you wanted to type the letter B, you would have to press the number 2 key twice.
The relationship of numbers and letters was distributed as follows:
- It had no letters.
- A, B and C.
- D, E and F.
- G, H and I.
- J, K and L.
- M, N and O.
- P, Q, R and S.
- T, U and V.
- W, X, Y, and Z.
According to the above, the table would be completed as follows.
Note: This question is incomplete because there is some missing information. Here is the missing information:
1. Complete this table to show the relation from letter to number.
