Consider the linear system of equations. y = –x + 9 y = 0.5x – 6 If the solution is (a,–1), what is a? a =
timofeeve [1]

Answer:

a = 10

Step-by-step explanation:

From the solution given, x = a and y = -1

Substitute for x and y in either of the equations

y = -x + 9

-1 = -a + 9

a = 9 + 1 = 10

PLS SOMEONE HELP ME
garik1379 [7]
Here are your answer's:

Number three would goes with "no relationship"...…
Number one would goes with "<span>causation</span>".....
Number two goes with "correlation"...…

<u>Correlation is the relationship between more than two things which is why it would go with number to because literacy rates go with the increase of doctors. Causation is like a cause and effect so in this case the cause would be a increase of the population and the effect would be more people who don't have jobs. No relationship would go with number three since how snowfall doesn't have anything to do with personal income. (which is how much a person makes) </u>

Hope this helps!

the terms in sequence A increases by 3. The terms in sequence B increase by 8. In which sequence do the terms form a steeper lin
il63 [147K]

Solution: The sequence B shows the steeper line.

Exanation:

The line having greater slope is always steeper than the other lines.

Since it is given that the sequence A increases by 3 and the sequence B increases by 8. It means for each additional value the sequences increased by 3 and 5 units respectively.

The slope of line is rate of change of one variable with respect to another variable.

The sequence A increased by 3, therefore the slope of line of sequence A is 3.

The sequence B increased by 8, therefore the slope of line of sequence B is 8.

Since the slope of sequence B is greater than the slope of sequence A, therefore the line of sequence B is steeper than the line of sequence A.

The sequence A can be defined as 3,6,9,12,.... and the sequence B can be defined as 8,16,24,....

So the coordinates points of sequence A are (0,0)(1,3),(2,6) and the coordinates points of sequence B are (0,0),(1,8),(2,16).

From the given figure it is notes that the blue line is steeper than red line.

Therefore, the sequence B shows the steeper line.

In timara math class there are, 12 boys and 15 girls which of the following in the ratio to boys and girls in timaras math class
tiny-mole [99]

Answer:

4:5

Step-by-step explanation:

If there are 12 boys and 15 girls, the ratio of boys to girls will be 12:15.

However, this can be simplified by dividing each number by 3. This can be done since both 12 and 15 are divisible by 3.

12:15

= 4:5

So, the ratio of boys to girls in Timara's class is 4:5
