Answer:
x=8 and y=3 (So, yes!)
Step-by-step explanation:
I will solve your system by substitution.
(You can also solve this system by elimination.)
−x+4y=4;−x+3y=1
Step: Solve −x+4y=4 for x:
−x+4y+−4y=4+−4y(Add -4y to both sides)
−x=−4y+4
-x/-1 = -4y+4/-1 (Divide both sides by -1)
x=4y−4
Step: Substitute 4y−4 for x in −x+3y=1:
−x+3y=1
−(4y−4)+3y=1
−y+4=1(Simplify both sides of the equation)
−y+4+−4=1+−4(Add -4 to both sides)
−y=−3
-y/-1 = -3/-1 (Divide both sides by -1)
y=3
Step: Substitute 3 for y in x=4y−4:
=4y−4
x=(4)(3)−4
x=8(Simplify both sides of the equation)
<u>Answer:</u>
x=8 and y=3
Answer:
Inter-quartile range
Step-by-step explanation:
When you have the quartile, you can use the IQR (interquartile range) to measure the dispersion.
IQR = Q3 - Q1
Movies: IQR = 195 - 162 = 33
Basketball: IQR = 225 - 170 = 55
Attendance at Basketball is more dispersed/spread out as compared to attendance at Movies
The graph is the horizontal line:
y=3 it has a slope of zero.
Function 2 is
y=3x+1, it is in slope-intercept form, y=mx+b where m is the slope and b is the y=intercept so in this case it has a slope of 3.
So the difference in slopes is 3-0=3
Answer:
The slope of line q is 
.
Step-by-step explanation:
We know that line p has a slope of , and that line p and line q are parallel. Parallel lines always have the same slope. Thus, the slope of line q must be as well.
