You would multiply each side of the equation by the reciprocal of 3/5 (5/3) because would cancel out 3/5 which would leave you with x and the answer.

Zigmanuir [339]

Answer:

9 inches

Step-by-step explanation:

Since the triangle are similar then the ratios of corresponding sides are equal

let x be the longer median, then

\frac{16}{24} = \frac{6}{x} ( cross- multiply )

16x = 6 × 24 = 144 ( divide both sides by 16 )

x = 9

4) Which graph represents a function?​
maxonik [38]

Answer:

C

Step-by-step explanation:

The other graphs do not pass the vertical line test (if you draw a vertical line through the line graphed, it should pass through once), but graph c <em>does</em> pass the test.

write the standard form of the equation of the circle that passes through the origin, (2.8,0), and (5,2)
Sphinxa [80]

Answer:

2.2y-2x = 0

Step-by-step explanation:

The standard form of the equation is normally y = mx + c where m is the gradient or the slope value while c is the y intercept.

As we know, the line passes through the origin, hence, it has no y intercept. This means our c has a value of zero.

What is left to find is the slope of the line.

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

m = (2 - 0)/(5 - 2.8)

m = 2/2.2 = 0.9091

so the standard form of the equation of the line is y = 0.9091x

OR

y = (2/2.2)x

OR

2.2y = 2x
