Solve the system of equations. 3x + 3y + 62 = 3
3x + 2y + 62 = 7
4x + 4y + 72 = 4
a. (x = 5, y = - 4,2 = 0)
b. (x = 4, y = -3, 2 = 1)
c. (x = 6, y=-5,2=-1)
d. (x = 7, y=-6, z = 2)

Amanager recorded the number of bicycles sold by his company each quarter. his projected sales after t years is given by the expression below. which of the following statements best describes the expression? a. the initial sales of 575 bicycles increases at the rate of 4% over 4 quarters. b. the initial sales of 575 bicycles increases at the rate of 18% over 4 years. c. the initial sales of 575 bicycles increases at the rate of 4% over t quarters. d. the initial sales of 575 bicycles increases at the rate of 18% over t years.

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
