Solve the following system. y = (1/2)x 2 + 2x - 1 and 3x - y = 1 The solutions are ( )and ( ) (remember to include the commas)

frozen [14]

$\begin{cases}y=\dfrac{1}{2}x+2x-1\\3x-y=1\end{cases}\\\\\\
\begin{cases}y=\dfrac{5}{2}x-1\3x-y=1\end{cases}\\\\\\
3x-\left(\dfrac{5}{2}x-1\right)=1\\\\3x-\dfrac{5}{2}x+1=1\\\\
3x-\dfrac{5}{2}x=0\\\\\dfrac{x}{2}=0\\\\x=0\\\\3\times0-y=1\\0-y=1\\y=-1\\\\\boxed{(x,y)=(0,-1)}$

The solutions are (0) and (-1)

Write an equation in slope - intercept form for the line that satisfies each set of conditions. answers only 24. slope 0.25, pas

Montano1993 [528]

24.) y = mx + b
slope(m) = 0.25
(0,4)...x = 0 and y = 4
now we sub and find b, the y int
4 = 0.25(0) + b
4 = b
so ur equation is : y = 0.25x + 4

26.) y = mx + b
slope(m) = 3/2
(-5,1)....x = -5 and y = 1
sub and find b, the y int
1 = 3/2(-5) + b
1 = - 15/2 + b
1 + 15/2 = b
2/2 + 15/2 = b
17/2 = b
ur equation is : y = 3/2x + 17/2

28.) y = mx + b
slope(m) = 4
(0,0)...x = 0 and y = 0
time to sub
0 - 4(0) + b
0 = b
so ur equation is : y = 4x + 0.....or just y = 4x

30.) (7,1)(7,8)....notice how the x's are the exact same number....this
means that ur line is a vertical line with a slope that is undefined.
ur equation is : x = 7

32.) (-2,-3)(0,0)
slope = (0 - (-3) / (0 - (-2) = (0 + 3) /(0 + 2) = 3/2

y = mx + b
slope(m) = 3/2
(0,0)...x = 0 and y = 0
sub
0 = 3/2(0) + b
0 = b
ur equation is : y = 3/2x + 0 or just y = 3/2x

34.) (1/3,0)(0,-1/4)
slope = (-1/4 - 0) / (0 - 1/3) = (-1/4)/(-1/3) = -1/4 * -3 = 3/4

y = mx + b
slope(m) = 3/4
(0,-1/4)...x = 0 and y = -1/4
sub
-1/4 = 3/4(0) + b
-1/4 = b
so ur equation is : y = 3/4x - 1/4
