Which of these linear functions has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3? Se
valentinak56 [21]

Answer: the correct options are B, D and F

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

m = slope = rate of change

Looking at the equations given, the three that apply are

B) slope = 7

y intercept = 4

It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3

D) y = 9x + 1

slope = 9

y intercept = 1

It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3

F) y = 8x + 5

slope = 8

y intercept = 5

It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3

10^2+12^2+14^2+......+26^2=??
Kazeer [188]

Answer:

3156

Step-by-step explanation:

  • <em>Used formula:</em>
  • <em>(1² + 2² + 3² + ... + n²) =1/6*n(n + 1)(2n + 1)</em>

--------

  • 10²+12²+14²+......+26² =
  • (2*5)²+(2*6)² + (2*7)² + ... + (2*13)² =
  • 4*(5²+6²+7²+...+13²) =
  • 4*(1²+2²+...+13² - (1²+2²+3²+4²)) =
  • 4*(1/6*13(13+1)(2*13+1) - (1+4+9+16)) =
  • 4*(1/6*13*14*27- 30) =
  • 4*(819 - 30) =
  • 4*789 =
