Answer:
1) Yes
2) No
Step-by-step explanation:
Substitute the x and y values of the given points into the equation and solve. If the result is a true statement, then they are solutions.
1) First, substitute the x and y values of (1,1.5) for the x and y in the given equation. Then, solve. (You can convert 1.5 from a decimal to a fraction, making it [tex]\frac{3}{2}[/tex].)
[tex]1.5= \frac{1}{4} (1) + \frac{5}{4} \\\frac{3}{2} = \frac{1}{4} +\frac{5}{4} \\\frac{3}{2} = \frac{6}{4} \\\frac{3}{2} = \frac{3}{2}[/tex]
The result is a true statement. Thus, (1, 1.5) is a solution to the equation.
2) Do the same with the point (12,4):
[tex]4 = \frac{1}{4} (12) + \frac{5}{4} \\4 = 3 + \frac{5}{4} \\4 = \frac{12}{4} +\frac{5}{4} \\4 \neq \frac{17}{4}[/tex]
The result is a false statement. The two values are not equal. Thus, (12,4) is not a solution to the equation.

Solve w^2+13w+42=0 by factoring.
Answers
Answer: {-7, -6}
Explanation: When an equation has a squared term in it,
it's called a polynomial equation.
The rule for solving a polynomial equation
is to first set it equal to 0, then factor.
Since this equation is already set equal to 0, we can factor the left side.
The left side is a trinomial that can be
factored as the product of two binomials.
The first term in each binomial will be a factor of the w².
Since w² factors a w · w, we use a w as our first term.
For the last terms, we use factors of 42 that add
to 13 and these factors are +7 and +6.
So we have (w + 7)(w + 6) = 0.
So either w + 7 = 0 or w + 6 = 0.
Solving for w in each equation, we find that our solution set is {-7, -6}.
Factor the expression below.

O A. (x - 1)(9x + 1)

Zahra is a waitress at a restaurant. Each day she works, Zahra will make a guaranteed
wage of $25, however the additional amount that Zahra earns from tips depends on
the number of tables she waits on that day. From past experience, Zahra noticed that
she will get about $14 in tips for each table she waits on. How much would Zahra
expect to earn in a day on which she waits on 10 tables? How much would Zahra
expect to make in a day when waiting on t tables?
Answers
Answer:
1. $165
Step-by-step explanation:
Zahra will expect to earn 14 *t +25 in a day on which she waits on "t" tables.
What is Linear function?A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph.
Given, Zahra is a waitress at a restaurant. Each day she works, Zahra will make a guaranteed wage of $25,
Let "t" be the tables Zahra is waitressing.
Since, she will get about $14 in tips for each table she waits on.
Total additional tip = t * 14
guaranteed wage = 25$
So, Total Zahra will earn for waitressing on "t" tables = 14 *t +25
For t = 10 tables
Zahra will earn for waitressing on 10 tables = 14 * 10 +25
Zahra will earn for waitressing on 10 tables = 165
Therefore, Zahra will expect to earn $165 in a day on which she waits on 10 tables.
