Answer:

Step-by-step explanation:

The slope (m) is the ratio of the difference in y-values to the corresponding difference in x-values:

m = (y2 -y1)/(x2 -x1)

m = (9 -0)/(4 -1) = 9/3

m = 3

The slope of the line is 3.

Find an equation of the line that goes through the points (10,34) and (-1,10)

kotykmax [81]

Answer:

Given points are ( 10 ,34 ) and ( -1 , 10)

Step-by-step explanation:

The equation of line is given by 

first we can find slope (m) 

= (y2 - y1) / ( x2 - x1)

= 34-10/10+1

 =24/11

Now the equation is

y - y1 = m ( x - x1) 

y - 10 = 24/11 ( x +11)

11 ( y - 10 ) = 24 (x + 11)

11y - 110 = 24x + 264

24x + 264 +110-11y =0

24x - 11y + 374 = 0

which is the required equation

Evaluate the function at the indicated values. f(x)= 6x^2+ 5x -12

seropon [69]

Step-by-step explanation:

We need to find the value of the function at the indicated value.

$f(x)= 6x^2+ 5x -12$

Indicated values are : f(-7), f(0), f(6), f(7)

To find f(-7), put x = -7 in the given function

$f(-7)= 6(-7)^2+ 5(-7) -12=247$

To find f(0), put x = 0 in the given function

$f(0)= 6(0)^2+ 5(0) -12=-12$

To find f(6), put x = 6 in the given function

$f(6)= 6(6)^2+ 5(6) -12=234$

To find f(7), put x = 7 in the given function

$f(7)= 6(7)^2+ 5(7) -12=317$

Hence, this is the required solution.

EFGH is a parallelogram. Find the measure of EG.

gayaneshka [121]

Answer: 64

Step-by-step explanation:

If EFGH is a parallelogram, its diagonals bisect each other meaning EJ and JG are congruent.

EJ = JG

4w + 4 = 2w + 18

Subtract 2w from both sides

2w + 4 = 18

Subtract 4 from both sides

2w = 14

Divide both sides by 2

w = 7

EG = EJ + JG

EG = 4w + 4 + 2w + 18

EG = 6w + 22

Now that we know what 'w' is, we can substitute it for 7

EG = 6 (7) + 22

EG = 42 + 22 = 64

The measure of EG is 64.

Hope that helped!
