Pani-rosa [81]4 years ago

Answer:

(1.63,4.18)

Step-by-step explanation:

1) look at the graph below: they intersect at about (1.5,4)

lets solve the systems by substitution:

since both equations are equal to y lets substitute the second equation into the first:

-6x+14=5x-4

-6x-5x=-14-4

-11x=-18

x=1.63

lets substitute x in the first equation:

5(1.63)-4=4.18

Hope this helps!

Can anybody help me with this one?
Murrr4er [49]

Answer:

  12 cm

Step-by-step explanation:

The rule regarding secants and/or tangents is that the product of distances from their common point to the two intersection points with the circle is the same.

For the tangent the "two" intersection points with the circle are the same point, so ...

  product of tangent lengths = product of secant lengths

  (8 cm)(8 cm) = (4 cm)(4 cm +x)

Dividing by 4 cm gives ...

  16 cm = 4 cm + x

  12 cm = x

Three of Santas helpers are a combined height of 11 feet and 6 inches. Clem is 15 inches shorter than Clyde who is 6 inches tall
Tresset [83]

Answer:

Clem's Height =38 Inches

Clyde's Height= 53 Inches

Chloe's Height = 47 Inches

Step-by-step explanation:

Let Clem's height be x, Clyde's height be y and Chloe's height be z

As given

x+y+z=11 feet 6 inches

As 1 Foot= 12 Inches so  (11*12+6)=138

x+y+z= 138 inches  (Equation 1)

Clem is 15 inches shorter than Clyde so:

x+15=y         (Equation 2)

Clyde is 6 inches taller than Chloe

z=y-6        (Equation 3)

Putting z's value from equation 3 in equation 1

x+y+y-6=138

x+2y=138+6

x+2y=144    (Equation 4)

Putting Value of y from equation 1 in equation 4

x+2(x+15)=144

x+2x+30=144

3x=144-30

x=114/3

x=38

Putting x's value in equation 1 to get the value of y

38+15=y

y=53

Putting value of y in equation 3

z=53-6

z=47

Checking by putting values of x,y,z in equation 1 to see whether all heights equal 138 inches or not

38+53+47=138

138=138
