The name of every student taking Algebra was listed alphabetically and numbered. The teacher uses
baherus [9]

Answer:

The number will be -63

Step-by-step explanation:

Here, we want to give the number of the chosen 25th student

We can see that the numbering follows an arithmetic sequence where a = 9 and d which is the common difference is (6-9) = -3

Mathematically, we can calculate the nth term using the equation below;

Tn = a + (n-1)d

in this case, n = 25, a = 9 and d = -3

So we have

Tn = 9 + (25-1)-3

Tn = 9 -3(24)

Tn = 9-72

Tn = -63

What is an equation of the line that passes through the point (-2, 2) and is parallel to the line 2x + y = 1?​
just olya [345]
2x+y=1 is in standard form so we will convert it to slope int form by subtracting 2x

y=-2x+1

the line we are finding the equation for is PARALLEL to this line here so the slope is the same

for the line’s equation we will put it in point slope form. y-y1=m(x-x1)

y-2=-2(x+2) is the answer!

Pepsi [2]
34 is 85% of 40 

Change the percentage into a decimal by dividing over 100:
\frac{85}{100} = 0.85

Divide 34 over 0.85:
\frac{34}{0.85} = 40

Y = x + 3
to test all of these, just use the visible x-coordinates on the grid and substitute them in the equation.
eg; y = (2) + 3 --> y = 5 . So the line would cross through (2,5)
