could you please awnser all 3 questions
Answer:
1) f(5) = 7
2) f(0) = -2
3) p(-7) = -17
Step-by-step explanation:
1) f(a) = 2a - 3
f(5) = 2 · 5 - 3 = 10 - 3 = 7
2) f(x) = 2x - 2
f(0) = 2 · 0 - 2 = 0 - 2 = -2
3) p(n) = 2n - 3
p(-7) = 2 · (-7) - 3 = -14 - 3 = -17
There were 275 students who rode the bus which represents 60% of school enrolment how many students enrolled
Answer:
458 (or 459 if you overestimate)
Step-by-step explanation:
Let's work backwards. we know that the 275 students are 60% of the total students enrolled, which we'll denote with x. Therefore:
0.6x = 275
Now divide both sides by 0.6 to get the answer:
x = 458.3
You can't have .3 students, so the answer is either 458 or 459 students, depending on if you want to over or underestimate.
Hope this helps!
brainly and points :)

The temperature at 6:00 am was -12 Fahrenheit. The temperature increased by 1/2 Fahrenheit each hour for 6 hours. What was the temperature, in degrees Fahrenheit,at noon?
Answer: -9°F
Step-by-step explanation:
From the question, we are told that the temperature at 6:00 am was -12 Fahrenheit and that the temperature increased by 1/2 Fahrenheit each hour for 6 hours.
The temperature, in degrees Fahrenheit, at noon would be:
= -12°F + 1/2(6)
= -12°F + 3°F
= -9°F

The function f is given by
f(x) = x² – 2x
Which statement is true about the graph of f ?
The x-intercept of the function are at (0, 0) and (2, 0). Then the correct option is D.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The function f is given by f(x) = x² – 2x.
f(x) = 0
On factorization, we have
x² – 2x = 0
(x – 2)x = 0
x = 0, 2
For x = 0, the function f(x) will be
f(x) = 0² – 2(0)
f(x) = 0
For x = 2, the function f(x) will be
f(x) = 0² – 2(2)
f(x) = 4 – 4 = 0
More about the function link is given below.

The length of Dwight's garden is 12.5 meters. Dwight measured it but made a measurement error of 6%. Find the lowest and highest measurement Dwight could have made. Show your work.
Answer: See Explanation
Step-by-step explanation:
From the question, The length of Dwight's garden is 12.5 meters but he measured it and made a measurement error of 6%.
The lowest measurement Dwight could have made will be:
= 12.5 - (6% × 12.5)
= 12.5 - (0.06 × 12.5)
= 12.5 - 0.75
= 11.75 meters
The lowest measurement Dwight could have made will be:
= 12.5 + (6% × 12.5)
= 12.5 + (0.06 × 12.5)
= 12.5 + 0.75
= 13.25 meters
Use the given similar triangles to find the value of x
I need the answer fast please!!
Answer:
I believe the answer is x=7
Step-by-step explanation:
3x and 4x-1 are corresponding sides and so are 14 and 18.
You cross multiply with the smaller triangle lengths at the top.
3x/(4x-1)= 14/18
Cross multiply to get
18(3x)= 14(4x-1)
54x=56x-14
Subtract 54x on the other side and add 14 to the other (or subtract 56x to the other side)
you get 14=2x and divide 14 by 2 to get x=7

Step-by-step explanation:
need more help? im glad to
first we need to simplify both sides :
5x + 13 * -2 = 2
5x + -26 = 2
5x - 26 = 2
Then we add 26 to both sides:
5x - 26 = 2
+26 +26
5x = 28
Then we divide both sides by 5:
5x/5 = 28/5
x = 28/5

3. What is the sum of the interior angles of a polygon with 32 sides?
Answer:
Step-by-step explanation:
To find the sum of an interior angle of a polygon, you have to follow these steps:
Interior angle= ( n - 2 ) ×180° all over n
So interior = ( 32 - 2 ) × 180° all over 32
Interior = 30 × 180 all over 32
Therefore your interior angle should be 168.75°
Choose all of the points that are solutions to the equation y = - 3x - 4.
