PLEASE SOMEONE HELP ME MY GRADE IS ON THE LINE I WILL GIVE 98 POINTS

2x - 3y - 9z = -32

x + 3z = 8

-3x + y - 4z = -8

Add all the equations together.

-3y - 10z = -32

By looking at the first equation, 2x - 3y - 9z = -3y - 10z.

So 2x = -z.

By looking at the second equation, x + 3z = (-0.5z) + 3z = 8.

So 2.5z = 8, and z = 3.2.

This means that x = -1.6.

Let's substitute into our original equations!

-3.2 - 3y - 28.8 = -32

4.8 + y - 12.8 = -8

Therefore, y = 0!

Since these answers do not contradict each other, they are dependent.

The answers are x = -1.6, y = 0, z = 3.2.

Please Help me with X and Y
Bad White [126]

Answer:

a) x = 69°

b) y = 69°

Step-by-step explanation:

a. Given that AB and CD are parallel lines, therefore:

x = 69° (alternate interior angles are congruent to each other)

b. y + 111° = 180° (consecutive interior angles are supplementary)

y = 180° - 111° (substraction property of equality)

y = 69°

Let f be the function given by f(x)=3xsinx. What is the average value of f on the closed interval 1≤x≤7 ?
Hoochie [10]

Answer:

-2.92178

Step-by-step explanation:

Given the function f(x)=3x\ sin x

The average,A is calculated using the formula;

A=\frac{1}{b-a}\int\limits^a_b F(x)\, dx \\\\A=\frac{1}{7-1}\int\limits^7_1 3x \ Sin \ x\, dx \\\\\\=\frac{3}{6}\int\limits^7_1 x \ Sin \ x\, dx \\\\\#Integration\  by\  parts, u=x, v \prime=sin(x)\\=0.5[-xcos(x)-\int-cos(x)dx]\limits^7_1\\\\=0.5[-xcos(x)-(-sin(x))]\limits^7_1\\\\=0.5[-xcos(x)+sin(x)]\limits^7_1\\\\=0.5[-6.82595--0.98240]\\\\=-2.92178

Hence, the average of the function is -2.92178
