The figure of y = x will be a straight line with slope 1 and they ;lie in the first quadrant and the third quadrant.

A linear function can be defined as the function whose graph is a straight line. It can also be defined as the function with one or more variables but does not have exponents to the variables or the exponent of the variable is 1.

We have to choose 5 ordered pairs first whose first and second coordinate are equal.

Let the coordinates be (-4, -4), (-2, -2), (0, 0), (2, 2) and (4, 4).

The ordered pairs are of the form (x, x), that both the coordinates have same value.

So we get a linear function y = x

The graph of a linear function will be a straight line.

Since y = x, the graph will be a straight line which tends to the positive direction and the slope of the line = 1.

That is , the angle that the line making with the X axis is 45°.

And the figure lies on first and third quadrant.

Hence the figure of y = x would be a straight line with slope 1.

Answer:

a = 241

b = 71

Step-by-step explanation:

a + b = 312 (#1)

a - b = 170 (#2)

(#1) + (#2) = 2a = 482.

a = 482 / 2 = 241.

b = 312 - 241 = 71.

Step-by-step explanation:

1) Find the Mean of all the numbers.

3+4+5+7+10+12+15=56

56/7=8 mean is 8

Now We Calculate Standard Deviation:

S=[tex]\sqrt{(3-8)^2+(4-8)^2+(5-8)^2+(7-8)^2+(10-8)^2+(12-8)^2+(15-8)^2}[/tex]

You take each number from the problem i.e 3,4,5...

and then you subtract the mean from it and then square it.

S=[tex]\sqrt{(-5)^2+(-4)^2+(-3)^2+(-1)^2+(2)^2+(4)^2+(7)^2}[/tex]

S=[tex]\sqrt{25+16+9+1+4+16+49}[/tex]

S=[tex]\sqrt{120}[/tex]

S=[tex]\sqrt{120}/7[/tex]

7 is the amount of data units given in the problem.

120/7=17.1428571429

[tex]\sqrt{17.1428571429}[/tex] =4.1403933560541

2t=14

t=7 hours

Answer:

7.00 hours

Step-by-step explanation:

They already did 4 problems and need to do 18 problems in total.

18 - 4 = 14 problems

2 problems/ per hour

14 problems/ 7 hours

It will take them 7 hours to finish. Since you said "Give your answer to two decimal places." You could write it as 7.00 hours.

Answer:

it is C

Step-by-step explanation:

The equation by completing the square (x + 7)^2 = 16 or  (x - 7)^2 = 16. The solutions to the equation are; A. x = -4 ± 3

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Consider the equation: x^2=-8x-7

1) Rewrite the equation by completing the square. Write it as (x+c)^2=d or (x-c)^2=d

Here the equation: x^2=-8x-7

x^2 + 8x + 7 = 0

Where a = 2, b = 8 , c = 7

(x+c)^2 = d or (x + 7)^2 = 16

(x-c)^2=d or  (x - 7)^2 = 16

2) The solutions to the equation are;

A. x = -4 ± 3
