Answer:
4 cups of water
Step-by-step explanation:
all they asked was how many cups were used and they said four
15 is the answer bc of the way it goes
Answer:
D, Yes, because there is a lot of variability in the science book data
Answer:
<h3>#6</h3>
Positive numbers less than 100 are 1 through 99.
- 1- digit = 3 numbers, zero excluded
- 2- digit = 3*4 = 12 numbers, zero excluded for the first digit
<u>Total:</u>
<u>Repetition is not allowed:</u>
- 1- digit = 3 numbers as above
- 2-digit = 3*3 = 9 numbers, minus one for the second digit
<u>Total:</u>
<h3>#7</h3>
abcd is the number.
- a = 2, then d = 4 or 0, b = 3 options, c = 2 options
- a = 3, no options
<u>Total:</u>
Answer: 2x + 5y = -5
Step-by-step explanation:
Two lines are said to be parallel if they have the same slope.
The equation of the line given :
2x + 5y = 10
To find the slope , we will write it in the form y = mx + c , where m is the slope and c is the y - intercept.
2x + 5y = 10
5y = -2x + 10
y = -2/5x + 10/5
y = -2/5x + 2
This means that the slope is -2/5 ,the line that is parallel to this line will also have a slope of -2/5.
using the formula:
= m ( ) to find the equation of the line , we have
y - 1 = -2/5(x -{-5})
y - 1 = -2/5 ( x + 5 )
5y - 5 = -2 ( x + 5 )
5y - 5 = -2x - 10
5y + 2x = -10 + 5
therefore :
2x + 5y = -5 is the equation of the line that is parallel to 2x + 5y = 10
