I need help on this plz and thank you?!?

Answer:

Step-by-step explanation:

Here we have the mixed numbers 1 5/8 and 9/10 and must sum them up to find the total number of miles Henry ran.

The LCD is 40:  Note that 40 is evenly divisible by both 8 and 10.

We convert 1 5/8 into the improper fraction 13/8.

Then we rewrite 13/8 as 65/40 and 9/10 as 36/40; now both quantities have the denominator 40.

Adding 65/40 and 36/40 yields 101/40 miles total, or 2.525 miles.

Answer:

Point of intersection (-11/3 , 1/3)

All distances from the vertices are

Step-by-step explanation:

The vertices of the triangle is A(-3,5) , B (1,1) and C (-7,-3)

We need to find the perpendicular bisector of the triangle first

let's take one side connecting A and B

mid point of A and B = (-1,3)

Slope of the line joining A and B = -1

slope of perpendicular to line joining A and B = 1

equation of line passing through (-1,3) with slope 1

y - 3 = 1(x-(-1))

y -3 = x+1

x-y = -4 ............(1)

similarly

mid point joining B and C = (-3,-1)

slope perpendicular to line joining B and C  =  -2

Equation of perpendicular bisector of line joining B and C =

y +1 = -2(x +3 )

y+1 = -2x -6

2x+y = -7 ..........(2)

On solving 1 and 2

x= -11/3 , y= 1/3

Distances

From A =

From B =

From C =

Answer:

Not sure how the question goes.

Step-by-step explanation:

2Y - 4X

2(9) - 4(2) = 18 - 8 = 10

Or

Y^2 - X^4

(9)^2 - (2)^4 = 81 - 16 = 65

y2-x4

to solve this u need to place the variables for the given value

y= 9

x=2

(9)2-(2)4

9 times 2 is 18

2 times 4 is 8

18-8=10

or if it is

y^2-x^4

9^2- (2)^4

9^2=81

2^4=16

81-16 = 65
