(1, 3)

General Formulas and Concepts:

<u>Algebra I</u>

Coordinates (x, y)
Reading a Cartesian (Rectangular) plane
Solving systems of equations by graphing

Step-by-step explanation:

Where the 2 lines intersect will be the solution set to the systems of equations.

If the lines are parallel, they will have no solution.

If the lines are the same, they will have infinite amount of solutions.

Find the slope of the line that passes through the following points. (-8,-1) (-4,-2)

lana [24]

Answer:

-1/4

Step-by-step explanation:

We can find the slope of a line given two points by using

m = (y2-y1)/(x2-x1)

= (-2- -1)/( -4 - -8)

= (-2+1)/(-4+8)

= -1/4

Answer:

d = 5/6t

Step-by-step explanation:

5 stories every 6 seconds

at 12 seconds, it would have travelled 10 seconds.

using this 2 data in this formula

(y-y1)/(x-x1) = (y2-y1)/(x2-x1)

Note : d = y, t = x;

d1 = 5, t1 = 6, d2 = 10, t2 = 12

we have

(d - 5)/(t-6) = (10-5)/(12-6)

(d - 5)/(t-6) = 5/6

d = 5/6(t-6) + 5

d = 5/6t -5+5

d = 5/6t

I don't know what's it asking me. what should I do?

Anton [14]

$n$ - a number
$n^2$ - its square
$n+n^2$ - the sum
$\leq$ - less than or equal
negative three - I don't have to explain this one, do I?

$n+n^2\leq-3$ - the sum of a number and its square is less than or equal negative three

Answer:

Option (b) is correct.

$(2^\frac{1}{4} )^4=2^\frac{1}{4} \times 2^\frac{1}{4}\times 2^\frac{1}{4}\times 2^\frac{1}{4}=2^{(\frac{1}{4}+ \frac{1}{4}+ \frac{1}{4}+ \frac{1}{4} )}=2^{1}=2$
