Answer:
y = 6
Step-by-step explanation:
line of an equation: y = mx +c
where c is y-intercept, m is gradient and y and x are the y and x coordinates.
For finding the line of an equation we first find a gradient
gradient = (y2 -y1) / (x2 - x1)
so; (6-6) / (7-(-5)) = 0/12 = 0
next using any pair of coordinates we will find the c (y-intercept)
6= 0 (-5) + c
c = 6
so the equation will be
y = mx + c
(add the values you just found)
y = (0)x + 6 (since anything multiplied by 0 is 0 so we can write its like;)
y = 6

3. A simple interest (I) varies jointly with the amount of principal (P) and the length of time. Suppose I = Php 600 when P = Php 10 000 and t = 2 years. What is the interest when P = Php 15 000 and t = 4 years?
Given:

Equation:
Solution:
Answer:
150120.83 ; 40 ; 1800
Step-by-step explanation:
Amount of share per person = x
Number of persons = y
x = k/y
k = constant of proportionality
k = xy
257,350 * 7 = 1801450
k = 1801450
If there are 12 persons ; y = 12
x = k/y
x = 1801450 / 12
x = 150120.83
2.) weight on Mars = m
Weight in earth = e
m α e
m = ke
48 = 120k
k = 48 / 120
k = 0.4
m = 0.4 * 100
m = 40
3.)
I α pt
I = kpt
600 = k * 10000 * 2
600 = 20000k
k = 600/20000
k = 0.03
I = 0.03 * 15000 * 4
I = 1800

I’ve been stuck on this for a few minutes. I’m not really sure what to do..
Answer:
Step-by-step explanation:
You know that the three angles of a triangle add up to 180°. If one angle is 38° and another angle is 67°, then the third angle must be 180°-38°-67° = 75°.
You have a straight line across the bottom, and three angles meeting in the middle of it. Those three angles add up to 180°. One of them is 75°, another is 50°, so the third angle must be 180°-75°-50° = 55°.
That leaves you with one unknown angle. ? = 180°-40°-55° = 85°

If , then what is mto the nearest degree?
Given:
[tex]\cos \angle A=\dfrac{342}{1000}[/tex]
To find:
The measure of angle A to the nearest degree.
Solution:
We have,
[tex]\cos \angle A=\dfrac{342}{1000}[/tex]
It can be written as
[tex]\angle A=\cos ^{-1}\dfrac{342}{1000}[/tex]
[tex]\angle A=70.00123^\circ[/tex]
[tex]\angle A=70^\circ[/tex]
Therefore, the measure of angle A to the nearest degree is 70 degrees.

slope is 2/3 y- intercept is -2
Answer:
y = (2/3)x - 2
Step-by-step explanation:
The equation of this line is y = (2/3)x - 2, where m is the given slope and -2 is the given y-intercept. We need only plug in the given values for m and b.
Answer:
[tex]y = \frac{2}{3} x -2[/tex]
Step-by-step explanation:
This is the slope-intercept form. The slope-intercept form is written as y = mx + b where m is the slope and b is the y-intercept. The y and x stay as they are.

Patryk has 7 cards.
There is a number on each card.
2 3 4 5 6 7 8
Patryk takes two of the cards at random.
He works out the product of the numbers on the two cards.
Work out the probability that the product is an odd number.
Answer:
Probability that the product is an odd number = [tex]\frac{1}{7}[/tex]
Step-by-step explanation:
Given - Patryk has 7 cards. There is a number on each card. 2 3 4 5 6 7 8
Patryk takes two of the cards at random. He works out the product
of the numbers on the two cards.
To find - Work out the probability that the product is an odd number.
Proof -
As we know that Product of two numbers is odd iff both the numbers are odd.
So, we have to find the probabilty that both the card that Patryk choose is odd
Now,
Total number of cards = 7
Total number of odd cards = 3
So, Probability = ³C₂ / ⁷C₂
= [tex]\frac{3!}{2! (3-2)!}. \frac{2! (7 - 2)!}{7!}[/tex]
= [tex]\frac{3!}{2! (1)!}. \frac{2! (5)!}{7!}[/tex]
= [tex]\frac{3!}{(1)!}. \frac{ (5)!}{7.6.5.4.3!}[/tex]
= [tex]\frac{ 5.4.3.2.1}{7.6.5.4}[/tex]
= [tex]\frac{1}{7}[/tex]
∴ we get
Probability that the product is an odd number = [tex]\frac{1}{7}[/tex]
