answer:
gradient is 4
Step-by-step explanation:
gradient is another way of saying slope
slope in the math is often used to show the speed of something
it's the m in y= mx+b
make the equation look like
y = mx + b
2y - 8x = -2
2y = 8x - 2
y= (8x-2)/2
y=4x-1
gradient is the number next to x
answer : gradient is 4
A <span>dodecagon has 12 sides
Sum of the interior angles = (12 - 2) x 180 = 1800</span>°
One interior angle = 1800 ÷ 12 = 150°
-------------------------------
Answer : 150°

Answer:
x=-1/2
Step-by-step explanation:
-3(x-4)= -9(x-1)
-3x+12= -9x+9
-3x+9x= 9-12
6x= -3
x=-3/6
x= -1/2
Answer:
1 and 3
Step-by-step explanation:
<span><span>1.
If we get an odd number first (probability 5/10 = 1/2), then the only way to get a number greater than 9 is the 10 (probability 1/9, since only 9 papers remain). This gives 1/2 * 1/9 = 1/18.</span></span><span><span>

We would expect that P(2 white cards) = P(1 white card)*P(2nd white card given 1 white card).</span></span><span><span /></span><span><span>This gives the equation 14/95 = 2/5 * x<span>
