This is for question 3
For perpendicular lines , the product of their gradient should give -1 for the answer and thus,
3×x=-1
x=-⅓, the gradient for the line.
Therefore c =
-2-3/c- 5 =-⅓
-1(c-5)=3(-2-3)
-c+5=-6-9
-c=-6-9-5
-c=-20
The negatives cancel each other leaving c as 20

A rectangle with area 36 square inches has a length that is 3 less than 3 times the width. Find the length and the width of the rectangle.
Answer:
length = 9 in ; width = 4 in
Step-by-step explanation:
1) formula of the area of a rectangle
A = base x width
2) write an equation with the given informations:
w x (3w-3) = 36
3) solve the equation
- multiply W by 3w and -3
3w^2 -3w = 36
- divide the two members by 3
w^2 - w = 12
- add up -12 at the two members
w^2-w -12 = 12 -12
w^2 - w - 12 = 0
- find two numbers whose sum is -1 and whose product is -12 and factorise the equation
(w-4)(w+3) = 0
- find the two solutions
w-4 = 0
w = 4
w+3 = 0
w = -3
4)remember that a length can’t be negative.
w = 4 is the only solution
5) find the length
4x3 - 3 = 9

Aidan bought a pizza cut into 5 slices. If he ate one slice for lunch, what percentage of the pizza remained uneaten?
Answer:
80%
Step-by-step explanation:
You started of with 5/5 once one slice was eat it became 4/5
you must then convert 4/5 into a percent
To convert a fraction to a percent, divide the numerator by the denominator. Then multiply the decimal by 100.
so 4 divided by 5 =0.8
0.8 x 100= 80
80%

Answer:
1) A segment is a "part" of a line that is delimited by two points, such that it starts in a point and ends in another.
In segments the "endpoints" can commute, so is the same DA as AD.
In the image we can see 3 segments:
DA
AS
DS
2) A ray starts in a point and passes through another point, extending infinitely.
In this case, the ray DA is different than the ray AD, because the ray DA starts in D and extends to the right (because point A is at the right of point D) infinitely.
And the ray AD starts in A and extends to the left infinitely (because point D is at the left of point A).
Also, because A and S are colinear, the rays:
ray DA = ray DS
Both of them start on D and extend infinitely to the right.
Then the rays we can see on this image are:
ray DA = ray DS
ray AS
ray SA = ray SD
ray AD.
4 rays in total.
3) The names of the segments are the ones we wrote in point 1.
DA
DS
AS
4) The segment that connects point D with point S is the segment DS.
5) The ray AS starts at A and goes to the right, then the one that goes toward the opposite of AS would be one that starts at A and goes to the left.
That one is the ray AD.

An endocrinologist is interested in the effects of depression on the thyroid. It is believed that healthy subjects have a mean thyroxin (a hormone related to thyroid function) level of 7.0 micrograms/100 ml and a standard deviation of 1.6 micrograms/100 ml. The endocrinologist wants to assess whether the mean thyroxin level is different for those with depression. She samples 35 subjects with depression and obtains a sample mean of 7.82 micrograms/100 ml for thyroxin. What null and alternative hypotheses should she test
Answer:
H0: μ = 7.0
H1: μ > 7.0
Step-by-step explanation:
The null hypothesis will equal and take up the value of the population mean value ;
The population mean value, μ is 7.0
Null hypothesis ; H0: μ = 7.0
The alternative hypothesis will align with the claim ; which will take up and side with the value and direction of the sample mean ; 7.82 micrograms/100 ml
7.82 > 7.0 (sample mean is greater Than the population mean).
Hence, the alternative hypothesis, H1 will be ;
H1 : μ > 7.0
