7x+y=11 where y= -5 So, when we substitute y in the equation then,
7x + (-5) = 11 that is 7x - 5 = 11....
So, B. is the right answer.
Answer:
raise ^that 4 to the power of -1+2 like this
raise ^to the power -2 like this
5-2=3 <Awnser
Answer:
Step-by-step explanation:
The table shows a set of x and y values, thus showing a set of points we can use to find the equation.
1) First, find the slope by using two points and substituting their x and y values into the slope formula, 
. I chose (-3, 13) and (0,17), but any two points from the table will work. Use them for the formula like so:
Thus, the slope is 
.
2) Next, identify the y-intercept. The y-intercept is where the line hits the y-axis. All points on the y-axis have a x value of 0. Thus, (0,17) must be the y-intercept of the line.
3) Finally, write an equation in slope-intercept form, or 
format. Substitute the 
and 
for real values.
The represents the slope of the equation, so substitute it for . The represents the y-value of the y-intercept, so substitute it for 17. This will give the following answer and equation:
C) 3 ounces
4 × 5 3/4 = 23
the total weight of the snack mix before the cheese puffs were added was 20 ounces. so 23 - 20 = 3 ounces.
Answer:
<u>P (not white) = 2/3</u>
Step-by-step explanation:
<u>Probability (not white)</u>
- No. of non-white marbles / Total marbles
- 8 + 14 + 10 / 8 + 16 + 14 + 10
- 32/48
- <u>2/3</u>
