For this case, the first thing we must do is define variables:
 x = number of quarters
 y = number of dimes
 We now write the system of equations:
 x + y = 28
 0.25x + 0.10y = 4.05
 Solving the system of equations we have:
 x = 8.33
 y = 19.66
 Rounding:
 x = 8
 y = 20
 Answer:
 
the college student has:
 
8 quarters
 
20 dimes

Help please? 10 points. Correctly
Romashka [77]

From the Figure :

Point A is (-3 , -3)

Point B is (6 , 6)

We know that, The Mid Point of Two Points (x₁ , y₁) and (x₂ , y₂) is given by :

\mathsf{\implies [(\frac{x_1 + x_2}{2})\;,\;(\frac{y_1 + y_2}{2})]}

\mathsf{\implies Midpoint\;of\;Line\;AB\;is\;[(\frac{-3 + 6}{2})\;,\;(\frac{-3 + 6}{2})]}

\mathsf{\implies Midpoint\;of\;Line\;AB\;is\;[(\frac{3}{2})\;,\;(\frac{3}{2})]}

\mathsf{\implies Midpoint\;of\;Line\;AB\;is\;(1.5,1.5)}

If the function f is given by f(x)= 4x -3, find the value of f(2+h)
Travka [436]
  • f(x)=4x-3

\\ \sf\longmapsto f(2+h)

\\ \sf\longmapsto 4(2+h)-3

\\ \sf\longmapsto 4h+8-3

\\ \sf\longmapsto 4h+5
