WILL GIVE 40 BRAINLY

Mathematics
1 answer:
irina [24]3 years ago

Answer:

(3,2)

Step-by-step explanation:

The method of variable substitution is a way of solving a system of equations. It involves solving one equation for a variable and then substituting in the expression that represents the value of the solved variable into the other equation. After doing so, one can solve for the unknown variable and then backsolve for the other variable.

y=-2x+8\\y=x-1

In this system, the second equation is already solved for (y), thus one can substitute that expression into the other equation in the system.

x-1 = -2x + 8

Now solve using inverse operations,

x -1 = -2x + 8\\+2x\\\\3x - 1 = 8\\+1\\\\3x =9\\/3\\\\x = 3

Backsolve to find the value of (y), substitute in the value of (x), and solve for the value of (y).

y=x - 1\\

Substitute,

y=(3)-1

Solve,

y=2

Thus, the answer to this system of equations is the following, (3,2).

Suppose you add 10% of a number to the number, and then you subtract 10% of the total. Is the result greater than, less then, or
anyanavicka [17]
Let's say the number is 9. 10% of 9 is 0.9. Add that to 9 and you would get 9.9. 10% of 9.9 is 0.99. Subtract and you would get 8.91. Then you could do the rest.

What is the probability
gulaghasi [49]

Answer: Last Option

P=0.4125

Step-by-step explanation:

In this case we have a uniform probability. In the graph the horizontal axis represents the possible values of the variable x and the vertical axis represents the probability P(x).

To calculate the probability that x is between 4.71 and 7.4 we calculate the area under the curve.

The horizontal length between 4.71 and 7.4 is:

7.4-4.1 = 3.3.

Then notice that the vertical length in this interval is 0.125.

Then the area of a rectangle is:

A = lw

Where l is the length and w is the width.

In this case we have to:

l = 3.3

w = 0.125

So

P = A = 3.3 * 0.125

P=0.4125
