Step-by-step explanation:
1. For any type of data a line graph and bar work but sense u are comparing a double line graph is best
Answer:
1) x = -1 or x = -10 (either of them are both correct)
2) x = 3 or x = -5
Step-by-step explanation:
Let's solve your equation step-by-step.
x2 + 11x + 10 =0
Step 1: Factor left side of equation.
(x + 1)(x + 10) = 0
Step 2: Set factors equal to 0.
x + 1 = 0 or x +10 = 0
x = −1 or x = −10
Answer:
x = −1 or x = −10
2x^2 + 4x − 30 = 0
Answer:
x = 3 or x = −5
we are given
slope is

y-intercept is (0,-3)

now, we can use slope intercept form of equation

where
m is slope
b is y-intercept
now, we can plug these values
we get

now, we have to write it in
Ax+By =C form
so, we will multiply both sides of equation by 3


Subtract both sides by 2x



so,
Answer is 
6 times 30 x 6= 180 So the answer is 6
Interval simply represent the set of numbers containing all numbers between any two numbers.
The representations of
are
and 
From the question, we have:
![(-\infty, -6]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%20-6%5D)
The above representation is in interval notation.
The interpretation is that;
The highest number in the interval is -6
The equivalent using set notation is:

The equivalent using inequalities is:
