How do I find QS here?

Mathematics
1 answer:
juin [17]3 years ago
4 0
Answer: 12.
To solve this problem, let's first solve for x. Thi is easiest done by figuring what QR is in terms of x using two equations, both from different lines. 
In the first line: QR = 15 - 4x. 
In the third line:QR = 13x - 1 - x = 12x - 1. 
Now, we have to set these equations equal to each other. 15 - 4x = 12x - 115 = 16x - 116x = 16x = 1
Next, we take line three, 13x - 1, and substitute x as 1. The answer is 12.

−7 − 3a = 17, then \frac{3}{4}a = ____?
Ilia_Sergeevich [38]

Answer:

-9/2

Step-by-step explanation:

-7-3a=17

-1-17=3a

-18=3a

a=-18/3

a=-6

The value of fac{3}{4} a = (3/4)(-6)

                                      = -18/4

                                      = -9/2

Four more than six times a number is at least 40. Find the possible range of values.
Setler [38]
1. Let x = #
2. "Five less than six times a number" can be written as: 6x - 5
3. "is at least" is the same as "greater than or equal to" and can be written as: >=
4. "nine subtracted from two times that number" can be written as: 2x - 9
5. the equation is: 6x - 5 >= 2x - 9
6. solve for x by grouping the x variable terms on one side and the constants on the other side:
6x - 5 >= 2x - 9
-2x +5 -2X +5
4x >= -4
7. divide each side by 4, and you get: x = -1

A scuba diver returning to the surface swims to move up quickly, then waits a few meters below the surface to avoid pressure iss
Juliette [100K]

Given:

The function f represents the diver's distance from sea level over time, in seconds.

f(x)=\begin{cases}3x+1 & \text{ if } -9

To find:

The correct statement for the domain.

Solution:

Domain is the set of input values for which the function is defined.

Here, x values are the input values and they represent time intervals on which the function is defined

Here, the possible intervals for x are -9.

Domain=(-9,-2]\cup (-2,1]\cup (1,7)

Domain=(-9,7)

Therefore, the domain is the time interval (−9, 7). Hence the correct option is A.
