1. Jervane is planning on buying a coffee and several donuts for a road trip. She wants to spend no more than $20 in total. Coffee costs $3 and donuts are $2 each. Write and solve an inequality to determine the maximum number of donuts that Jervane can buy. Be sure to include units on your answer.( I'll give you brainless)
Answer: 8
Step-by-step explanation: Given:
Total money Jervane can spend = $20.
Cost of a coffee = $3.
Cost of a donut = $2.
To find: Maximum number of donuts Jervane can buy.
Solution:
Let the number of donuts she can buy be .
She wants to spend no more than $20 in total.
So,
As the number of donuts can only be a natural number.
Hence, the maximum number of donuts that Jervane can buy are 8.

Can someone PLEASE solve this quadratic equation by factoring with the steps? :(
y= x squared +2x - 2
Answer:
There are no simple factors to this expression. You can however solve for x, giving you:
x = -1 ± √(y + 3)
Step-by-step explanation:
There is no simple pair of factors to this equation, so we'll have to go through the full process. You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2. We can however solve for x:
[tex]y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}[/tex]

if a system of linear equation has an infinite number of solutions, what do you know about the graph of the system?
a. the lines intersect at one point
b. the lines are parallel
c. the lines are the same
d. the lines cannot he graphed
Answer:
c. the lines are the same
Step-by-step explanation:
A system of linear equations has an infinite number of solutions because the lines are the same. The correct answer would be an option (C).
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
If a system of linear equations has an infinite number of solutions, it means that the equations are equivalent and represent the same line in the coordinate plane.
Therefore, the graphs of the two equations will be the same line, meaning that the lines are coincident. They won't intersect at one point, nor will they be parallel, as the definition of an infinite number of solutions is that they are the same line. And they can be graphed, as they represent a single line in the coordinate plane.
Hence, the correct answer would be option (C).
