y = 4   this states that there's a point on the line which always has a coordinate of (x,4) where x can be any number.

7 - v/4 = 3   7 - 3 = v/4   4 = v/4   v = 16

D. 24   Prime numbers are numbers that can only be divided by itself and 1.   In your case, 24, can be divided by 1, 2,3,4, 6, 8 , 12 and itself(24).

since we have two repeating numbers, which are (97), there are also two 9s in the denominator:   so,   3 + 97/99 = 3 97/99

since you only have one repeating number (2) the denominator is composed of one 9 only.   2/9

let x be the total points for all students let y be the best score     x/16 = 83         -------> x = 83*16 = 1328   (x - y)/ 15 = 82   (1328 - y)/15 = 82   1328 - y = 15 * 82   1328-...

first, we don't need how much you invested to figure out when it doubles. We just need the interest rate. Let x be the number of months until the investment has doubled.   since it's compounded monthly, we divide interest by 12   .065/12 = .00542   (1.00542)12x...

a) 127000(1 - .024)10 = .7843*127000 ≈ 99609 people   b) 95000 =127000(1 - .024)x    ---------> 95000/127000 = .976x = ln (95000/127000) = x ln .976 ------>11.95 years.

y = -x + 3,     (-2,-2)   we know that the above equation is in the form: y = mx + b, where m is the slope. Any line parallel to the given line will have the same slope (m = -1). To find the equation of the parallel line we use the slope and the point given...

A     74 B     34 C    83 + x   A + B +C = 180   74 + 34 + 83 + x = 180     191 + x = 180   x = -11

Let L be length Let W be width     L = 2W - 3

Not enough info. You are not given pages per chapter so you won't know how many pages the book has.

you will need 26 * 31 = 806 employees. The age has nothing to do with the problem.

we have equation -4x + 3y = 24   to find x-intercept, plug in 0 to y:  -4x + 3(0) = 24 ----->-4x = 24 -----> x = -6   so x-intercept is (-6,0)   to find y-intercept, plug in 0 to x: -4(0) + 3y = 24 ----> y = 8   so y-intercept...

output is one half input   .5 * -4 = -2 .5 * -2 = -1 .5 * 6 = 3 .5 * 8 = 4

8 oz. \$4.48   10 oz. \$5.52   let's create points using weight for x and price for y:   (8, 4.48) (10, 5.52)   solve for slope:   5.52 - 4.48     =    1.04    = \$.52/oz.  ...

a square means that it's a rectangle with all four sides equal in length. So, since area for square is side squared (s2):   s2 = 196   use a calcuator to get the square root of 196 which is 14.   so length is 14 feet.

4(1/C + 2/C) = 1   (1/C + 2/C) = 1/4   3/C = 1/4   C/3 = 4   C = 12   Since Julissa is twice faster than Chris, Julissa can do the job at half of Chris' time (1/2 * 12 = 6 hours)   Chris can...

Let x be the number of 4 point questions, so number of 2 point questions is 40 - x:   120 = 4x + 2(40 - x)   120 = 4x + 80 - 2x   120 = 2x + 80   120 - 80 = 2x   40 = 2x   x = 20   there are 20...

convert equation to y = mx + b form where m is slope and b is y-intercept:   so we have,   4x + y = -4   y = -4x - 4   therefore m = -4 and b = -4
