Hey there!!
Given equation :
... x² + x - 6 = 0
... x² -2x + 3x - 6 = 0
... x ( x - 2 ) + 3 ( x - 2 ) = 0
... ( x + 3 ) ( x - 2 ) = 0
Option ( b )
Hope it helps!
Answer:
y=-8x-2
Step-by-step explanation:
The formula for slope is y2-y1/x2-x1. Take coordinate (0,-2), which is the y-intercept. We'll call that (y2,x2). Coordinate (8,-3) is (y1,x1). Put that into the formula you get, 0-8/-2-(-3). You get -8/1 which is negative 8. We now have the slope. Slope intercept form equation is y=mx+b. M is slope, so we put our slope in the equation and get, y=-8x+b. B is the y-intercept which is given. So we know that the equation to this line in slope-intercept form is y=-8x-2.
The answer is 7. Double negatives cancel out so -4x-1=4 then add three
Answer:
5
Step-by-step explanation:
I assume you mean "Find the ratio 30 : 6 in simplest from".
Ratio means division, so it's 30/6 = 5
Answer:
17
Step-by-step explanation:
5 + 6 - 5 + 4 +7 - 3 + 6 - 3 = 5 + 6 + 4 + 7 + 6 - 5 - 3 - 3
= 28 - 11
= 17
