4y = 3x - 2      To find the y-intercept, let x = 0 and solve for y. 4y = -2 y = -1/2   (0,-1/2)   To find the x-intercept, let y = 0 and solve for x. 0 = 3x - 2 2 = 3x 2/3 = x     (2/3,0)

√(n/25) = √n                     5

Let x = the length of the third side Let x + 5 = the length of each equal side P = a + b + c 31 = x + 2(x + 5) 31 = x + 2x + 10 21 = 3x 7cm = x Each equal side  = x + 5 = 7 + 5 = 12 cm   Let x = the measure of the...

Let d = the number of dimes Let q = the number of quarters d + q = 27      d = 27 - q .10d + .25q = 4.35       Multiply both sides of this equation by 100 to get rid of the decimal points. 10d + 25q = 435 10(27-q) + 25q = 435 270...

15(.20) = 3 ounces

Start with the Point-Slope Form since that is the information you are given. y - y1 = m(x - x1) y + 4 = 1(x + 1) y + 4 = x + 1 y = x - 3

1/2 divided by 1/8 = (1/2)(8/1) = 4 slices

5(3.75) = 18.75 feet 3 feet = 1 yard 81.75/3 = 6.25 yards

Do you mean 45 minutes to paint one room? If so, it would take Carlos 45(7) minutes = 315 minutes 60 minutes = 1 hour 315 minutes(1 hour/60 minutes) = 5 1/4 hours to paint 7 rooms 45 minutes = 3/4 hours (3/4)(9)(13.50) = \$91.13

A set of "n" distinct elements has 2n subsets. Set A has 22 subsets: {a,b}, {a}, {b}, ∅

i = prt i = 3500(.04)(2) i = \$280   i = prt i = 3500(.04)(10) i = \$1400

5x + 2x > 9x - 4 7x > 9x - 4 -2x > -4 x < 2

Let x = the weight of the smaller box Let x + 8 = the weight of the larger box x + x + 8 = 32 2x = 24 x = 12 pounds x + 8 = 20 pounds

A = lw 30 1/3 = 6 1/2(w) 91/3 = (13/2)w        Multiply both sides by 2/13. (2/13)(91/3) = (2/13)(13/2)w 14/3 = w 4 2/3 inches = w   OR  Divide 30 1/3 by 6 1/2.   Sorry, I automatically use algebra.

A = P(1 + r/n)nt A = 1000(1 + .02/4)4(5) A = 1000(1.005)20 A = 1000(1.10489) A = \$1105

Use the distance formula: d = √[(x2 - x1)2 + (y2 - y1)2] d = √[(9-5)2 + (1-8)2] d = √[42 + (-7)2] d = √(16 + 49) d = √65 d = 8.1

2 weeks = 14 days 16 ounces - 1 pound   Let x = the number of pounds of flour the baker will use in two weeks x = 4.5(14) x = 63 pounds   63(16) = 1008 ounces

Let h = the height of the building 10/3 = h/15      Cross multiply 3h = 150 h = 50 feet

I couldn't show you a graph online. However, the lines intersect at the point (0,-2). So, they are independent systems.
