write an equation in point slope form for the line that has a slope of 9/4 and contains the point (3,-4)
denis-greek [22]

Answer:

y+4 = 9/4(x-3)

Step-by-step explanation:

The point slope form of an equation is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

Substituting in what we know

y--4 = 9/4(x-3)

y+4 = 9/4(x-3)

Because all of the ending values are given in feet, find the window dimensions in feet. Convert the length of 3 feet, 9 inches s
MA_775_DIABLO [31]

Answer: 3.75 ft

Step-by-step explanation:

Here we are given the measure of the length of a window. Generally the length is given in the International System of units format (meters); however, in this case we are given the length in feet and inches:

3 ft+9 in

Now, before converting this whole measure to feet, we have to know that 1 ft=12 in, then we can perform the conversion:

9 in \frac{1 ft}{12 in}=0.75 ft

This means 9 in=0.75 ft

Hence:

3 ft+9 i=3 ft+0.75 ft=3.75 ft This is the measure of the length of the window in feet.

A rectangle has a length of 19 in and a height of 11 in. Another rectangle has a length of 95
scoundrel [369]

Answer:

Option D. No,they are not similar because their side lengths are not proportional.

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem If the rectangles are similar

then

The ratio of its corresponding lengths must be equal to the ratio of its corresponding heights

<u><em>Verify</em></u>

\frac{95}{19}=\frac{6.5}{11}\\\\95*11=19*6.5\\\\1,045\neq123.5

therefore

The rectangles are not similar because their side lengths are not proportional.
