Answer:
(-1,-2)
Step-by-step explanation:
There is a solution where the two expressions intersect. We can plug in what we know in the first equation in the second.
x= -1
y=3x+1
y= 3(-1)+1
y= -3+1
y= -2
Plugging y value in the equation to find x:
-2=3x+1
-3=3x
x= -1
Therefore, the point is (-1,-2)

To find the range subtract from the biggest to the lowest, so it would be 86 - 13 which equals to 73.
Your lower or first quartile would be 42 and your upper or third quartile would be 74.
Answer:
75 + 20 = 5 (15 + 4) = 5 × 19 = 95
Step-by-step explanation:
The prime factors of 75 are 3 × 5 × 5.
Again, the prime factors of 20 are 2 × 2 × 5
Therefore, the greatest common factor of 75 and 20 is 5.
Now, 75 + 20
= 5 × 15 + 5 × 4
= 5(15 + 4) {Using the distributive property of multiplication}
= 5 × 19
= 95 (Answer)
