<span>3x + 2y = 7
y = –3x + 11
replace </span>y = –3x + 11 into 3x + 2y = 7
3x + 2y = 7
3x + 2(–3x + 11) = 7
3x -6x + 22 = 7
-3x = 7 - 22
-3x = -15
x = 5
<span>y = –3x + 11
y = -3(5) + 11
y = -15 + 11
y = -4
x = 5 and y = -4
answer: </span><span>D. (5, –4)</span>
Answer:
± sqrt(3)i = x
Step-by-step explanation:
0 = x^2 +3
Subtract 3 from each side
-3 =x^2 +3-3
-3 =x^2
Take the square root of each side
±sqrt(-3) = sqrt(x^2)
±sqrt(-3) = x
We can split sqrt(-3) into sqrt(3) sqrt(-1) and we know that the sqrt(-1) is i
± sqrt(3)sqrt(-1) = x
± sqrt(3)i = x
Point slope form is y-y1=m(x-x1)
M is the slope
y1 and x1 come from the point given
Answer:
Y+8=1/2(x-0)
If it should be simplified y+8=1/2x
The x value is 0 because when the line intercepts the y axis x=0
