If y varies directly as x and inversely as z and y = 4 when x = 2 and z = 7, find y when x =
S_A_V [24]

Answer:

y = 28

Step-by-step explanation:

Given that y varies directly as x and inversely as z then the equation relating them is

y = \frac{kx}{z} ← k is the constant of variation

To find k use the condition y = 4 when x = 2 and z = 7, then

4 = \frac{2k}{7} ( multiply both sides by 7 )

28 = 2k ( divide both sides by 2 )

14 = k

y = \frac{14x}{z} ← equation of variation

When x = 6 and z = 3 , then

y = \frac{14(6)}{3} = 14 × 2 = 28

Find the value of y if the line through the two given points is to have the indicated slope.
Masteriza [31]
Slope is the change in y/ change in x so the equation will be:
-2= (1-y)/(-6-(-5)) -> simplify -> -2= 1-y/-1 -> multiply both sides by -1 -> 2=1-y -> simplify and -y= 1 -> y=-1

Complete the statement of congruence for the triangles.
Hoochie [10]

If you are proving a congruence of triangles then you need to match the corresponding parts to the triangle you are proving congruent.

BAC would then be congruent to MJR because of the corresponding angles

B is the same angle as M

A is the same angle as J

C is the same angle as R
