Answer:

Its B.

Step-by-step explanation:

FYI you cannot completely solve the equation because there are variables

(so since we dont know what value the variables are, we cant solve the equation fully) , so the most we could do is simplify the equation.

We have to use the distributive property because there are parenthesis.

8 x 3x = 24x

and

8 x 2 y = 16y

Now just combine the answers together: 24x + 16y

Hope this helps :)

To get from his house to the lecture hall at school, Lin walked west 651 feet. After class, he walked northeast 910 feet to the

Ahat [919]

The general direction that Lin walked from the gym to his house is; B: Lin walked southwest, creating an obtuse triangle.

<h3>How to interpret distance bearing?</h3>

We are given;

Distance between the lecture hall and gym = 910 feet.

Distance between the gym and Lin apostrophe's house = 615 feet.

Distance between the lecture hall and Lin apostrophe's house = 651 feet.

Now, since this 3 distances form a triangle and the 3 distances are unequal, then we can call it an obtuse triangle since he walked west and then walked northwest.

Now, since he walked back to his house from the gym, we can say that he walked southwest if we picture the bearing of his first two directions.

$\sf \: 12x^{4} ( - 56x^{3} {y}^{2} )$

Multiplying a positive and a negative equals a negative: (+)×(-)=(-)

$\sf \: { - 12x}^{4} \times 56 {x}^{3} {y}^{2}$

Calculate the product

$\boxed{ \tt - 672x^{7} {y}^{2} }$

Tamara finds the sum of two number cubes rolled at the same time. The chart below shows all possible sums from the 36 possible c

Georgia [21]

Answer:

18 times

Step-by-step explanation:

Sample space ; roll of 2 number cubes = 6^2 = 36

Sum of 4 in 2 cube rolls = 3

Probability = required outcome / Total possible outcomes

P(sum of 4) = 3 / 36 = 1 / 12

If number cube is rolled 216 times :

Probability on 1 roll * Number of rolls

(1 / 12) * 216

0.0833333 * 216

= 18

What is the domain and range of the function

Stells [14]

Answer:

Option d is correct.

Domain = all real number

range = positive real numbers

Step-by-step explanation:

Given the function: $y=f(x) = a^x$

Domain of the function is all real numbers except where the expression is undefined.

In this case, there is no real number that makes the expression undefined.

Domain of f(x) = $(-\infty , \infty)$ = {a | a∈R}

Range is the set of all valid f(x) values.

$(0,1) \cup (1, \infty)$

$\{y | y\neq 1 , y>0\}$

Therefore, Domain is all real number and the range of function is positive real number
