Answer: 110 mph
Step-by-step explanation: 275 / 2.5 = 110 mph
Answer:
12 slides
Step-by-step explanation:
Okay so we know that Val:
takes 1/6 hours to do each slide
has 2hrs
To figure this question out we have to divide fractions.
To divide a fraction you multiply the dividend by the reciprocal of the divisor.
My simple dictionary:
Dividend - The First number in a fractional problem
Divisor - The second number in a fractional problem
Reciprocal - a fraction flipped upside down so that the numerator is now the denominator. For example 3/2 = 2/3
Now that that is done let's look at the problem.
We have to divide 2 by 1/6 or multiply 2/1 by 6/1
To multiply a fraction we just multiply numerator by numerator and denominator by denominator.
2 x 6 = 12
1 x 1 = 1 (duh)
So, in conclusion, Val can create 12 slides in 2 hours :D
that was some really explicit stuff .-.
-4 or
Rise 4 and run 1 to the left (that's what makes it negative)
For this case we have that by definition, the slope of a line is given by:
Where:
and are two points through which the line passes.
Question 1:
According to the image, we have the following points:
Substituting we have:
Thus, the slope is:
Question 2:
According to the image, the line goes through the following points:
Substituting we have:
Thus, the slope is:
Answer:
Slope 1:
Slope 2:
1) −3x+y=−13
4x+5y=1
−3x+y=−13( this is y)
Now it's time for you to add
−3x+y+3x=−13+3x
Next you will substitute (3x-13) for y in the equation 4x+5y=1
4x+5y=1
4x+5(3x−13)=1
19x−65=1 <<<(for this part you start to simplify)
19x−65+65=1+65
19x=66
Then you get
19x/19= 66/19
x=66/19
Now it's time for you to substitute 66/19
y=3x−13
y=3(66/19)−13
Then for y you get
y=−49/19
So the answer for number one is
x=66/19 y=49/19.
2)x−y=−4
x−y=1
First things first add y to both sides
x−y+y=−4+y
Your result is:
x=y−4
It's time to substitute
x−y=1
y−4−y=1
−4=1
What you need to do now is add
−4+4=1+4
and you get 0=5
For this problem you have no solutions.
Hope this helps
