5. The end of his round on Saturday was a -5, and the end of his round on Sunday was a 0. The difference between -5 and 0 is 5, which means that the integer that represents the change in the golfers score is 5.
Answer: (3,3)
To begin, I turned x into a value of 1 by multiplying it by 3;
f(3) = 1/3(3) + 2
f(3) = 1 + 2
It would then become quite clear what the answer could then be..
f(3) = 3
meaning when x = 3, y = 3
Answer: b, c, e
( 3/3 = 2/2 = 4/4 = 1)

Answer:
86%
Step-by-step explanation:
A percentage is a number or a ratio expressed as a fraction over 100. For example, 50% in fraction form is known as 50/100. 45% is known as 45/100.
Lets say the fraction was 43/50. We already know that a percentage is a number expressed as a fraction over 100, in order to convert this fraction into a percentage, we would have to multiply the denominator by a certain number in order to make it 100.
43/50 = x/100
If we multiply 50 × 2 = 100, so now we have to do the same for the numerator, and also multiply it by 2.
43 × 2 = 86
50 × 2 = 100
Now we know that the fraction is 86/100, now in order to convert it into percantage form, it would just be 86%

I want you to imagine as you read this or you can draw through the help of my explanation and see yourself:
1↪Draw triangle ABC where BC>AC
2↪D is any point on AC such that CD=CB
3↪Roughly drawing , you can assume CD=CB and and join BD
4↪SO triangle ABC which is a big triangle is divided into Triangles ABD and BDC
5↪See in triangle BDC ,CD=CB so, base angles of isosceles triangle are equal:
<CDB=<CBD = x (assume) which means x is acute angle since CDB and CBD are are in same triangle with same measure and there can't be any two obtuse angle in any traingle. So x must be acute.
6↪Now see in traingle ABD,
<ADB=180-<CDB=180-x=obtuse angle
...check yourself ...just subtract any acute angle from 180 you will get only obtuse angle (ie angle greater than 90)
That means in triangle ABD , one angle ADB is obtuse which means remaining <ABD and < BAD are acute. [PROVED]
❇Main Concept Used Here:
↪In any triangle there can be maximum of one obtuse angle...so remaining two must be acute angle otherwise interior angles sum can't be equal to 180.
