Answer:
y = 2x
Explanation:
To write the equation of a line u use the formula y = mx + b, where
y = y coordinate
m = slope
x = x coordinate
b = y intercept
One thing about parallel lines is that they always have the same slope. If you want to find a line parallel to y = 2x + 3, then the parallel line will also have a slope of 2.
So far, then, the equation would look like this: y = 2x + b
To find the y-intercept, we substitute in the values from (3,6) into the equation because the line passes through that point. So:
y = 2x + b
(6) = 2(3) + b
6 = 6 + b
6 - 6 = b
b = 0
Since the y-intercept is 0 (so the line passes through the origin), it doesn't need to be written on to the end of the equation.
y = 2x + 0 is just
y = 2x
That's your final equation! hope this helps!
What is the output of the function when the input is 10? On the graph plot this point and label its coordinates
Answer:
Output value = 20
Step-by-step explanation:
Graph of any function is made up of two values → Values on x axis and Values along y axis.
x values represent the input values and y values represents the output values.
For every x value there is a y value because of which the data set is called to a function.
In other words, a function can't have two output values for a single input value.
If the input value of function is = 10
Then for x = 10, out value (along y axis) will be = 20
Therefore, Output value of the given function is 20.

The solution is, Option B Negative ,as time passes, speed decreases.
What is Correlation?Positive Correlation= With Increase in x value, y value also increases or vice versa, we call it positive correlation.
Negative Correlation= With Increase in x value, if y value decreases or vice versa, we call it negative correlation.
here, we have,
Description of the Graph
1. The Relation between , Speed and time is depicted on the graph.
2. Minute = x coordinate
Miles per hour= y coordinate
The points shown on the graph , describing the relationship are, (5,15),(10,13.8),(15,11),(20,10),(25,9.8).
There are two types of Correlation
Positive Correlation= With Increase in x value, y value also increases or vice versa, we call it positive correlation.
Negative Correlation= With Increase in x value, if y value decreases or vice versa, we call it negative correlation.
As you can see from the points plotted on the graph ,with increase in x value , y value decreases.
So it is negative correlation.
As, time passes, Speed Decreases, So it is a Negative Correlation.
Option B Negative ,as time passes, speed decreases.

because if it a has been 1 minute(m=1) the 35(1)=w --> w=35 for for one minute there is 35 words 35m=w
for 1 i cannot see, but if d says 3/4 and x=3/4 then d is the answer
Answer:
(For your second question.):

Step-by-step explanation:
Why?
It states in the problem itself that miles types 35 words per minute.
"w" stands for words
'm' stands for minutes.

A student has heard that spinning pennies on a table, rather than flipping them in the air, results in tails side up 65% of the time. If this is true, what is the probability that a student who spins 4 pennies will have them all land tails side up? 0.0150 0.1785 0.8215 0.9850
so I believe it is C 0.8215
The probability is 0.1785
What is probability?The study of how likely certain events are to occur is known as probability. In its simplest form, it is concerned with the fall of a game's cards or the roll of a dice. However, probability is also essential to life and science as a whole. Probability is used, for example, in weather forecasting and figuring out how much your insurance premiums will cost.
Given probability of tail by spinning a coin is 65% = 0.65
p(t) = 0.65 and p(h) = 0.35
where h= head and t= tail
coin spins 4 time
p(t) for first time = 0.65
p(t) for second time = 0.65 x 0.65 =0.4225
p(t) for third time = 0.65 x0.65 x 0.65 = 0.274
p(t) for fourth time = 0.65 x 0.65 x0.65 x 0.65 = 0.178
Hence probability that a student who spins 4 pennies will have them all land tails is 0.178

pls tell me which to pick (a,b,c,or d)
Answer:
B (Y, N, N)
Step-by-step explanation:
a) y = 1/3x, so each value satisfies it. This is true.
b) If "a" is "Y" then b has to be no
c) 1 * 11 = 11
2 * 2 = 22
3 * 5 = 15
The last equation does not follow the rules for the previous two equations, so it is no.
Thus, the answer is B (Y, N, N)

Step-by-step explanation:
As the figure can be split in to 3 geometric figure,
Rectangle , Triangle and Semi circle ,
So first find the area of these figures then add up them ,
Area of rectangle = Length * width
Length = 20m m and width = 14 mm
hence
Area of rectangle = 20*14 = 280 mm^2
Now ,
Are of Circle = [tex]\\ \pi *d^{2} /4[/tex]
Then Area of semi circle = [tex]\\ \pi *d^{2} /8[/tex]
Hence we have d= 20mm
Putt in semi circle formula we get,
Area of Semi Circle= (3.14)*400/8 = 157 mm^2
Now area of triangle = 1/2 * length*width
length =32-20 = 12 mm
width = 14 mm
putt in the formula we get ,
Area of triangle = 1/2*12*14 = 84 mm^2
Now add these 3 Areas to get total Area,
Total Area = 84+157+280 = 521 mm^2

If you were to teach a friend how to solve the following two-step equation : 3x + 18 = 48, what would you say, step by step? You may work it out first before you start your writing.
Answer:
Step-by-step explanation:
3x + 18 = 48
Bringing like terms on one side
3x = 48 - 18
3x = 30
x = 30/10
x = 3
Answer:
x = 10
Step-by-step explanation:
Subtract 18 from both sides.
3x=48-18
Simplify 48-18 to 30.
3x=30
Divide both sides by 3.
x= 30/3
Simplify 30/3\ to 10
x=10
x=10
