The solutions for the given problems we have:
1) The solution of the inequality is:
x ≤ 2
2) The absolute value equation has two solutions:
z= 2
z = -12
3) The correct matches are:
5y + 2 = 5y + 8 this has no solutions
2*(y + 4) = 2y + 8 this has infinite solutions
5y + 2 = 2y + 8 This has a single solution.
Here, we have,
Remember that solving means to isolate the variable in one side of the expression.
1) We have the inequality:
-4x + 17 ≥ 9
-4x ≥ 9 - 17
x ≤ -8/-4
x ≤ 2
This is the solution of the inequality.
2) We have the absolute value function:
|5 + z| + 3 = 10
|5 + z| = 10 - 3 = 7
We can decompose this into:
5 + z = 7
5 + z = -7
Then the two solutions are:
z = 7 - 5 = 2
z = -7 - 5 = -12
3) The correct matches here are:
5y + 2 = 5y + 8 this has no solutions, these are parallel lines.
2*(y + 4) = 2y + 8 this has infinite solutions (all real numbers).
5y + 2 = 2y + 8 This has a single solution.

Answer:
81%
Step-by-step explanation:
If there is a 30 percent chance a student will fail a class at Fresno State, we can simply multiply the percentage by the probabilities of all students failing. Every option available:
P(All four fail) = 1 student fails * 2 students fail * 3 students fail * 4 students fail
P(All four fail) = 0.3 * 0.3 * 0.3 * 0.3
P(All four fail) = 0.0081
0.0081 = 81%

The temperature reach to 48 degree Celsius in 2.5 minutes.
What is Equation?
Equations are mathematical statements with twoalgebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
The temperature T in degrees Celsius of a liquid t minutes after heating is given by the formula T=8√t.
So, when the temperature = 48 degree Celsius
48 = 8√t
48/ 8 = √t
6 = √t
t= 2.445
t= 2.5 min
Hence, the time will taken 2.5 min.

T=temperature
t=time in minutes.
If T=48, we have to calculate the time.
48=8√t
(48)²=(8√t)²
2304=64t
t=2304 / 64=36
answer: 48 degrees Celsius will be reached in 36 minutes.

The only thing I'm a little unclear on here is what you mean by
the "legs" of an isosceles triangle.
I'm going to assume that your isosceles triangle is standing on
the side you call the "base", and the "legs" are the two slanty ones,
standing up, which are the two equal sides.
With that set-up, x + 1 = -x + 7
Add x to each side: 2x + 1 = 7
Subtract 1 from each side: 2x = 6
Divide each side by 2 : x = 3
Finally, if the base is (3x - 3), then that's (3·3 - 3) = 6 .
