Answer:
i think its -3
Step-by-step explanation:
Because any number raised to the power of 0 is 1 or -1.
so itll be (-1) + (-1) × 2 =
-1 + (-2) = -1 -2 = -3
Answer:
also 75°
Step-by-step explanation:
the angles across each other at a crossing point of 2 lines must be equal.
so, 2 = 3.
and the angles at the crossing point with a parallel line are simply a "mirror" or rather a copy of the angles at the crossing point with the first line.
so, 2 = 3 = 6 = 7
and 1 = 4 = 5 = 8
A quadratic has the form ax^2+bx+c
To factor a quadratic you want to find two values, j and k, which satisfy two conditions...
j*k=a*c and j+k=b
In this case ac=-140 and b=4.
The only values possible are j=14 and k=-10
so jk=-140 and j+k=4 which are the conditions we needed to satisfy...
Now you remove the linear, or "b term", from the original equation and replace it with jx and kx... and in this case you will have:
-2h^2-14h+10h+70 now you can factor out the greatest common factor from the first pair of terms and the second pair of terms...
-2h(h+7)+10(h+7) which is equal to
(-2h+10)(h+7) and you can factor the first term again if you wish...
-2(h-5)(h+7)
The equation is
. This is because the slope form is y = mx + b, and if -5 is the slope, -5 = m. 2 is the y-intercept, and the y-intercept is b.
