Work out the m and c for the line
y=x+6
Answer:
m - 1
c - 6
Step-by-step explanation:
[tex]y=x+6\\\\[/tex]
The equation is in slope-intercept form.
y = mx + c
m - slope
c (or b) - y -intercept
Usually if the slope is one it will not be written.
y = 1x + 6
The slope is one.
6 takes 'c's place, so it is the y-intercept.

The total number of victories for a football team exceeds the number of defeats by 4, with no draws. Knowing that if 44 jojos, how many victories were there?
Answer: 24
Step-by-step explanation:
Let the number of defeats be represented by x.
Since the total number of victories exceeds the number of defeats by 4, then the number of victories will be:
= x + 4
We then add the number of victories and losses together and equate them to 44. This will be:
x + x + 4 = 44
2x + 4 = 44
2x = 44 - 4
2x = 40
x = 40/2
x = 20
Therefore number of victories will be:
= x + 4
= 20 + 4
= 24

Michael has a bank account that he is using to save money to buy a new bike. He hopes to save more and more money each week. The equation that models the situation is y=50(1.5)^x where x is the number of weeks and y is the total amount of money he has saved. What do the 50 and 1.5 mean in the context of the situation? (Hint: One of the numbers involves a percent!)
Answer:
50 is the initial bank account balance of $50
1.5 represents that his balance grows by 50% (1.5x) each month, or in other words that he deposits 50% of his previous month's balance into his account each month.

HELP DUE BY 12!!! WILL MARK BRAINLIEST
Answer:
79 and 35
Step-by-step explanation:
1. Let a be the missing angle.
23 + 78 + a = 180 ( Sum of all angles in a triangle is 180)
101 + a = 180
a = 180 - 101
a = 79
2. Let b be the missing angle
105 + 40 + b = 180
b = 180 - 145
b = 35

The straight line L, has equation y=3x-4
The straight line 1, in perpendicular to L, and passes through the point (9.5)
Find an equation of line L
Answer:
y = -1/3 x + 32/3
Step-by-step explanation:
Find an equation of line L
Given the equation bog L1 as y ,= 3x-4
The slope of the line L1 is 3
Since both lines are perpendicular, the product of their slope is -1, hence ;
LL1 =-1
3L = -1
L = -1/3
Slope of the required line is -1/3
Get the equation in point lope form
y-y0 = m(x-x0)
y-9 = -1/3(x-5)
3(y-9) = -(x-5)
3y-27 = -x+5
3y = -x+5+27
3y = -x+32
y = -1/3 x + 32/3
This gives the required equation

Step-by-step explanation:
kim has 8 vanilla candles, 4 cherry candles and 6 raspberry candles. what is the probability that kim will choose a cherry candle?
The probability that Kim will choose a cherry candle is [tex]\frac{2}{9}[/tex] OR 0.22
From the question,
We are to determine the probability that Kim will choose a cherry candle out of the possible candles
From the given information
Number of vanilla candles = 8
Number of cherry candles = 4
Number pf raspberry candles = 6
∴ Total number of candles = 8 + 4 + 6 = 18
Using the formula
[tex]Probability = \frac{Number\ of\ favorable\ outcomes}{Total\ number\ of\ outcomes}[/tex]
For the probability to choose cherry candle
Number of favorable outcome = 4
Total number number of outcomes = 18
∴ Probability of choosing cherry candle = [tex]\frac{4}{18}[/tex]
Probability of choosing cherry candle = [tex]\frac{2}{9}[/tex] OR 0.22
Hence, the probability that Kim will choose a cherry candle is [tex]\frac{2}{9}[/tex] OR 0.22
