Answer:
Is there a graph that goes with this question? If there is, is it possible for you to upload it to the question? So when i answer its completely correct.
Step-by-step explanation:
B) {56, 66, 95, 90, 57, 66, 69, 68, 76, 64, 51}
{56, 66, 95, 90, 57, 66, 69, 68, 76, 64, 51} is the only data set that matches the maximum and minimum, upper and lower quartile, and median values.
7(7x -4)
49x-28
We can factor a 7 from each term
49x = 7*7x
28 = 7*4
12
12 divided by 1 using long division is 12. As long as a number is divided by 1 the number is the same as the dividends number.
Let's solve your system by substitution.
−3x+y=−2;y=4x
Rewrite equations:
y=4x;−3x+y=−2
Step: Solvey=4xfor y:
y=4x
Step: Substitute4xforyin−3x+y=−2:
−3x+y=−2
−3x+4x=−2
x=−2(Simplify both sides of the equation)
Step: Substitute−2forxiny=4x:
y=(4)(−2)
y=−8(Simplify both sides of the equation)
x=−2 and y=−8
