Answer:
a. The 1's are heavier than the x's. There isn't a whole number on top of the x's.
b. The equation would be 2x<9 because the 9 is greater(heavier) than the 2x. To continue to solve you would divide 2 by both sides. That would turn into x<9/2.
Step-by-step explanation:
75000. one hundread thousand more would be 100,000 more that what is given making it 175,000
Answer:
Therefore,
....Standard form.
......Numerical Coefficients.
Step-by-step explanation:
Given:

To Find:
a ,b , c
Solution:
Quadratic:
A quadratic equation is an equation of the second degree.
Meaning it contains at least one term that is squared.
The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.
Here it is given as

Adding 6 on both the side we get


Which is Quadratic Equation in STANDARD form Where,

Therefore,
....Standard form.
......Numerical Coefficients.
Answer:
See below.
Step-by-step explanation:

because we combine like terms. You will essentially ignore the x and just do -2 + 1, which is -1. So, the answer would be -1x which is simply just -x.
To see why we can combine like terms, use the distributive property. So we have:

This is the same thing as saying:

Factor out the x:

Add:

And simplify:
