Answer:
Lauren could solve 7.5 + 3 / 2 to find the y-intercept.
Lauren could solve (1/2)(4+0.5) to find the x-intercept.
Finding the midpoint is equivalent to partitioning a line segment a 1:1 ratio.
Step-by-step explanation:
Answer:
2/5, 3/7, 1/2, 5/8, 5/6
Step-by-step explanation:
change the fractions into decimals and place them in order from least to greatest, then revert back to it's original form which would be a fraction.
Answer:
<u><em>The answer would be 17</em></u>
Step-by-step explanation:
You are going to multiply -1 by -5 , that will equal positive 5
So you get 12+5 = 17
If the sequence is -4,-8,-16,.. then the seventh term be -256.
Given a sequence be -4,-8,-16,...
We are required to find the seventh term of the sequence.
If we carefully observe the sequence then we will find that the sequence is a geometric progression.
Geometric progression is a sequence which has a common ratio between all the terms.
Ratio of 2nd and 3rd term=-8/-4=2
Ratio of 3rd and 2nd term=-16/-8=2
Because the ratio is equal, so the sequence will be called a geometric progression.
Nth term of G.P=a
7th term=-4*
=-4*64
=-256
Hence if the sequence is -4,-8,-16,.. then the seventh term be -256.

Answer:
There are no real factors for this.
Step-by-step explanation:
We could answer this either by checking each listed expression to see whether it is a factor of 9r^2-4r+1, or
We could take the coefficients of 9r^2-4r+1, determine the quantity b²-4ac (called the 'discriminant') and draw a conclusion based upon whether the discriminant is -, + or 0.
Let's use the 2nd approach.
Here, a = 9, b = -4 and c = 1.
Then the discriminant is b²2 - 4ac, or (-4)² - 4(9)(1), or 16 - 36.
Since 16 - 36 is negative, we conclude that this 9r^2 - 4r + 1 has NO REAL FACTORS.
