A
 (-2c-3d) (- 11) (- 2c-3d) (- 11) left parenthesis, minus, 2, c, minus, 3, d, right parenthesis, left parenthesis, minus, 11, right parenthesis
 C
 (66c + 99d) \ cdot \ dfrac {1} {3} (66c + 99d) ⋅ 3
1 left parenthesis, 66, c, plus, 99, d, right parenthesis, dot, start fraction, 1, divided by, 3, end fraction
<span> E
 11\cdot(2c+3d)11⋅(2c+3d)11, dot, left parenthesis, 2, c, plus, 3, d, right parenthesis
</span> answer
 (-2c-3d) (- 11) = 22c + 33d
 (66c + 99d) * 1/3 = 22c + 33d
 11 * ( 2c+3d) = 22c + 33d

Find the x-intercepts and y-intercept for the parabola below. Write answers as (x,y) coordinates.
poizon [28]
Assuming the function is y=2x^2-4x-6
the x intercepts are where the graph hits the x axis or where y=0
the y intercepts are where the graph hits the y axis or where x=0


x intercepts
set y=0 and find x
0=2x^2-4x-6
0=2(x^2-2x-3)
what 2 numbers multiply to get -3 and add to get -2?
-3 and 1
0=(2)(x-3)(x+1)
set to 0
0=x-3
3=x
0=x+1
-1=x

x intercepts are at x=-1 and 3 or the points (-1,0) and (3,0)



y intercepts are where x=0
set x=0
y=2(0)^2-4(0)-6
y=0-0-6
y=-6
y intercept is at (0,-6)



x intercepts are at (-1,0) and (3,0)
y intercept is at (0,-6)

Write an equation in slope -intercept form for a line that passes through (-2,7) and (14,21)
Georgia [21]
(-2,7) and (14,21)

Find the slope by using the formula m =  \frac{y2 - y1}{x2 - x1}

Plug in the numbers. m = \frac{21 - 7}{14 - - 2} &#10; \\  m= \frac{14}{16}  =  \frac{7}{8} &#10;

Write it in point slope form first

y - y1 = m(x - x1)
y - 7 = 7/8(x - -2)
y - 7 = 7/8x + 1.75
   + 7            +7

y = 7/8x + 8.75

Our final equation would be: <span>y = 7/8x + 8.75</span>

Find the solution for the system of linear equations by graphing: y=x <br> Y=2x -4
Arte-miy333 [17]

Answer:

x and y = 4

Step-by-step explanation:

Since y=x --->         x=2x-4

                              -x  -x

0=x-4            

+4   +4  ------------------> Therefore, x= 4 and y= y

If you could graph both lines you would find they intersect at (4,4)
