Step-by-step explanation:

3. Substitution, Elimination, and Graphing are ALL three methods to solve a system of equations, whether they are in three variables or two. The only differense is that with graphing, you will easily spot when a system is dependent [Infinitive Solutions], inconsistent [no solution], and\or consistent [one solution]. With elimination, you want to eliminate one set of variables [set to zero] so that it will be alot simpler solving the system, then latre on, substitute whatever value solved for the remaining set of variables back into the system to solve for the eliminated variable. Finally, with substitution, all you have to do is choose which variable you want to solve for in all three equations, or two. It really does not matter which one, as long as you follow the proper universal concept in using the Order of Operations.

2. This is self-explanatory really. The only time you cannot use any method is when the linear equations form parallel lines. Otherwise, you will always have one or infinite solutions.

Answer:

255+35-75

Step-by-step explanation:

Since we are trying to find the account balance, we consider anything in or going to the account to be positive.

255 is positive since it is in the account

35 is positive since it is going into the account

75 is negative because it is going out of the account

so the final expression to express the amount is the checking account would be 255+35-75

Answer: 54.4 mph

Step-by-step explanation:

First find the distance to the train station. If it took Carlos 4 hours to come back driving at 68 mph, the distance is:

= Speed * time

= 68 * 4

= 272 miles

This means that Carlos drove for 5 hours to cover 272 miles the first time. His average speed was therefore:

= Distance / time

= 272/5

= 54.4 mph

Answer:

8190 ways

Step-by-step explanation:

Given

[tex]Teachers = 6[/tex]

[tex]Students = 15[/tex]

Selection

[tex]Students = 4[/tex]

[tex]Teachers = 5[/tex]

Required

Number of ways of selection

4 students can be selected from 15 students in:

[tex]Students= ^{15}C_4[/tex]

Similarly.

5 teachers can be selected from 6 teachers in:

[tex]Teachers= ^{6}C_5[/tex]

So, the required number of selection is:

[tex]Selection = ^{15}C_4 * ^6C_5[/tex]

Apply combination formula:

[tex]Selection = \frac{15!}{(15-4)!4!} * \frac{6!}{(6-5)!5!}[/tex]

[tex]Selection = \frac{15!}{11!4!} * \frac{6!}{1!5!}[/tex]

[tex]Selection = \frac{15*14*13*12*11!}{11!*4*3*2*1} * \frac{6*5!}{1*5!}[/tex]

[tex]Selection = \frac{15*14*13*12}{4*3*2*1} * \frac{6}{1}[/tex]

[tex]Selection = \frac{32760}{24} * 6[/tex]

[tex]Selection = 1365 * 6[/tex]

[tex]Selection = 8190[/tex]

Answer:

[tex]\boxed {\boxed {\sf \frac{5}{6} \ or \ 0.833}}[/tex]

Step-by-step explanation:

Probability can be found by dividing the favorable outcomes by the total outcomes.

[tex]P=\frac{favorable \ outcomes}{total \ outcomes}[/tex]

In this problem, a favorable outcome is not picking a black jelly bean. The total outcomes is the total number of jelly beans.

[tex]P( \ not \ black \ jelly \ bean)=\frac{not \ black \ jelly \ beans}{all \ jelly \ beans}[/tex]

[tex]P( not \ black \ jelly \ bean )=\frac{10}{12}[/tex]

This fraction can be reduced. Both the numerator and denominator can be divided by 2.

[tex]P(not \ black \ jelly \ bean)=\frac{10/2}{12/2}[/tex]

[tex]P(not \ black \ jelly \ bean)=\frac{5}{6}[/tex]

Probabilty can also be written as a decimal.

[tex]P(not \ black \ jelly \ bean)=0.833[/tex]

The probabilty of not picking a black jelly bean is 5/6 or 0.833

Answer:

(4/7)/5= 4/35 or .1142857 or .11

Step-by-step explanation:

Answer:

I suppose that here we have:

"(4, - 2) flipped over the x-axis"

Regardless of that, i will answer this in a kind of general way.

When we have a point (x, y) and we do a reflection over the x-axis (or the line y = 0, is the same) the reflected point will be (x, - y)

If we instead had a reflection over the y-axis (or the line x = 0) the reflected point will be (-x, y)

Then if we have the point (4, -2) and we have a reflection over the x-axis, the sign of the y-component needs to change.

Then the reflected point will be (4, -(-2)) = (4, 2)

Answer:

176.

Step-by-step explanation:

112 = 2*2*2*2*7

For a cube number there must be 3 or a multiple of 3 of each factor.

So we multiply  by 2*2 and 7 * 7 to give 2^6 * 7^3 which is 21952.

The answer is 4*49

= 176.

Checking that 21952 is a cube:

- the cube root is 28,

Step-by-step explanation:

Answer:

We conclude that the initial value of the function is 6.

Hence, option D is correct.

Step-by-step explanation:

The initial value of the function can be determined by setting x = 0 and determining the corresponding y value.

In other words, the initial value is basically the y-intercept of the graph.

It is the output value when the input value x = 0.

Given the graph, it is clear that:

at x = 0, y = 6

Thus, at x = 0, the value of y is 6.

i.e. the y-intercept b = 6.

Therefore, we conclude that the initial value of the function is 6.

Hence, option D is correct.

Answer:

6

Step-by-step explanation:

The initial value is the y-intercept or where the line crosses the y axis.

hi! im chimken and i have your answers!

x = 43/8

( 98 ÷ 14 + x - 9 / 24 ) • 40 = 480

( 7 + x - 9 / 24 ) • 40 = 480

( 53 / 8 + x ) • 40 = 480

265 + 40x = 480

40x = 480 - 265

40x = 215

x = 43 / 8
