Answer:
A good estimate for the slope is 95/60
Step-by-step explanation:
The formula to calculate the slope between two points is equal to
From the graph take the points
(0,0) and (80,125)
substitute
simplify
Multiply by 3.75 both numerator and denominator
therefore
A good estimate for the slope is 95/60
The graph is shown below
<h3>What is graph?</h3>
Graph is a mathematical representation of a network and it describes the relationship between lines and points.
As, the equation x² + y² < 25 represents equation of circle.
So, the graph will be of the form circle.
and, y² <6x is the equation to represent parabola
So, the graph will represent a parabola.

Answer:
I think last one, not sure
Step-by-step explanation:
Answer: Matrix B is non- invertible.
Step-by-step explanation:
A matrix is said to be be singular is its determinant is zero,
We know that if a matrix is singular then it is not invertible. (1)
Or if a matrix is invertible then it should be non-singular matrix. (2)
Given : A and B are n x n matrices from which A is invertible.
Then A must be non-singular matrix. ( from 2 )
If AB is singular.
Then either A is singular or B is singular but A is a non-singular matrix.
Then , matrix B should be a singular matrix. ( from 2 )
So Matrix B is non- invertible. ( from 1 )
Hi!
<h3>We need to isolate x on one sides, and whatever we do to the equation we have to do on both sides. </h3><h3>Subtract 5 from both sides. </h3>
4x + 5 - 5 = 12 - 5 - 7x
4x = 7 - 7x
<h3>Add 7x to both sides. </h3>
4x + 7x = 7 - 7x + 7x
11x = 7
<h3>Divide by 11 on both sides</h3>
11x/11 = 7/11
<u>x = 7/11</u>
<h2>The answer is x = 7/11</h2>
Hope this helps! :)
