I am going to use the PEMDAS order. Parenthesis, Exponents, Multiply, Divide, Add, Subtract
Multiply ⇒ 5 * 32 = 160
42 + 160 - 42 ÷ 23
Divide ⇒ - 42 / 23 = -1.83
42 + 160 - 1.83
Add ⇒ 42 + 160 = 202
202 - 1.83
Subtract ⇒ 202 - 1.83 = 200.17
42 + 5 * 32 - 42 ÷ 23 = 200.17

A. He will have saved $25.
B. He will have saved $150.
C. He will have saved $500.
He will have saved $50.
Answers
The answer is D
This is because if for every $50 he saves $5, and he has saved a total of $500, you can set up a proportion to find out how much money he has saved at that point.
The proportion is as follows:
50/5 == 500/x
x is equivalent to the amount of money he has saved
You can cross multiply to get the following equation:
50x == 2500
To isolate x, you must divide both sides by 50, giving you an answer of:
x = 50
This is the same as option D

vertex= ?
axis line of symmetry equation?
Answers
Answer:
The vertex is at ( 3.5, -0.25)
and the axis of symmetry is x = 3.5.
Step-by-step explanation:
Convert to vertex form:
y = x^2 - 7x + 12
y = (x - 3.5)^2 - 3.5^2 + 12
y = (x - 3.5)^2 - 0.25
y = (x - 3.5)^2 - 0.25.
So the vertex is at ( 3.5, -0.25)
and
the axis of symmetry is x = 3.5.
Final answer:
The vertex of the parabola y = x² - 7x + 12 is at (3.5,-0.25) and the equation of the axis of symmetry is x = 3.5.
Explanation:
The given quadratic equation is y = x² - 7x + 12. To determine the vertex and the equation of the axis of symmetry, we need to first find the x-coordinate of the vertex, which is determined by the formula -b/2a. Here in our equation, a = 1 (coefficient of x²) and b = -7 (coefficient of x), so x = -(-7)/(2*1) = 3.5.
The x-coordinate of the vertex is thus 3.5. Now, to get the y-coordinate of the vertex, we substitute x = 3.5 into our equation, so y = (3.5)² - 7*(3.5) + 12 = -0.25. Therefore, the vertex of the parabola is at (3.5,-0.25). The line of symmetry of a parabola always passes through the vertex, so the equation of the axis of symmetry is x = 3.5.

Hey there! :) The answer to your question is 2 years and 9 months. I got the answer because there are 12 months in 1 year. So 24 months is 2 years. 24+9=33 months.
Hope I helped! :D
