-2(x - 2) = -3 - 21 I need help with that question, I've been trying to solve it for hours but i cant find the answer ​
iVinArrow [24]

Answer:

x = 14

Step-by-step explanation:

you would first distribute the -2 with x - 2, which should give you -2x + 4, and you want to do the -3 - 21, which would give you -24, then subtract 4 from -2x + 4, then you should have -2x = -28, then divide it by -2, which should give you x = 14

Simplify the expression<br> (-3+4k) - (-2+ 7k)
DedPeter [7]

Answer: −1−3k

Step-by-step explanation:

Distribute:

(−3+4k)−1(−2+7k)

(-3+4k)+{2-7k}

Eliminate redundant parentheses:

(−3+4k)+2−7k

-3+4k+2-7k

Add the numbers:

−3+4k+2−7k

−1+4k−7k

Add the same term to both sides of the equation:

−1+4k−7k

−1−3k

Consider the random variables X and Y with joint density function ???? f(x,y)= x+y, 0≤x≤1;0≤y≤1 0, elsewhere. (a) Find the margi
sp2606 [1]

a. The marginal densities

f_X(x)=\displaystyle\int_0^1(x+y)\,\mathrm dy=x+\frac12

and

f_Y(y)=\displaystyle\int_0^1(x+y)\,\mathrm dx=y+\frac12

b. This can be obtained by integrating the joint density over [0.25, 1] x [0.5, 1]:

P(X>0.25,Y>0.5)=\displaystyle\int_{1/4}^1\int_{1/2}^1(x+y)\,\mathrm dx\,\mathrm dy=\frac{33}{64}
