Answer: 19
Step-by-step explanation: when two negative signs are next to eachother, you need to add the two numbers.
Answer: 5x + 2y = 8 = x=-2/5y+8/5
y = 3x - 7= x= 1/3y+7/3
Step-by-step explanation:
Answer:
I'll explain
Step-by-step explanation:
For an inequality and equation to solve them is almost the same
A difference is that, in an inequality, if there is a negative, when you divde the sign will change (<,>,=,) Hope this helps.
The slope of the line is
Explanation:
Given that a coordinate plane with a straight line passing through the points , and
We need to determine the slope of the line.
The slope of the line can be determined using the formula,
Since, the points , and lie on the straight line and the slope of all the points in a straight line have the same slope.
Hence, let us consider the points and
Let us substitute these points in the slope formula, we have,
Simplifying, we get,
Dividing, we get,
Hence, the slope of the line is
Answer:
x 0
Step-by-step explanation:
You need each of the square roots to be positive numbers, and the only for that to happen is if the variable is 0 or a positive number.
