Show steps to solve 2-16.5=4-7.5​

Mathematics
1 answer:
ASHA 777 [7]3 years ago
7 0

Answer:

11=0

or

-11=0

keep in mind that you get these answers by completely simplifying the equation, but they are both false

Step-by-step explanation:

step 1: simplify both sides

2-16.5 simplifies to -14.5

4-7.5 simplifies to -3.5

so you get -3.5 = -14.5

step 2: add one side to the other to get a zero on one side

add 3.5 on both sides to get 0=-11

or

add 14.5 on both sides to get 11=0

step 3: evaluate the statement

since both -11 and 11 are not equal to 0, this statement is false

What is the shape of the graph of the function?<br> h(t) = 0.32 - 0.5t
allsm [11]

Answer:

Answer (a) is correct

Step-by-step explanation:

This is not the same function that was given to you in the problem.

As you have typed it, this function is linear.  The one in the homework problem is exponential.

We will ignore the linear function h(t) = 0.32 - 0.5t.

We will focus on h(t) = 0.32 - 0.5^t.

If t = 0, then 0.5^t = 0.5 ^0 = 1, and so h(0) = 0.32 - 1 = -0.68  =>  (0, -0.68)

Continuing with a few other t values chosen at random:

h(1) = -0.18

h(2) = 0.07

Notice that h is increasing as x increases!

h(4) = 0.2575

and so on.

answer A is the correct one.

h(1) = 0.32 - 0.5^1 = 0.32 - 0.5 = -0.18

Let a= x^2 +4. Rewrite the following equation in terms of a and set it equal to zero.
swat32

Answer:

C and G

Step-by-step explanation:

(x^2+4)^2+32=12x^2+48 is written as (x^2+4)^2+32=12x^2+48.

We can simplify the expression using the term a by replacing x^2 + 4 with a.

(x^2+4)^2+32=12x^2+48\\(x^2+4)^2+32=12(x^2+4)\\a^2 + 32 = 12a\\a^2 - 12a + 32 = 0

This factors into (a-4)(a-8). Solve by setting each factor equal to 0 and solve for a.

a-4 = 0                 a=4

a-8=0                   a=8
