Find the equation of a line that is parallel to y = 2x - 10 and passes through the point (3, -2).

Whitepunk [10]

Parallel, therefore gradient is the same = 2
y-y1=m(x-x1)
y+2=2(x-3)
y+2=2x-6
y=2x-8

If C is between A and B, then answer the following if AB=40, AC= 2x+10, CB= 3x-5

Marat540 [252]

If C is between A and B, then, we can write the equation

$AB = AC + CB$

Substitute the value of AB and the expressions for AC and CB in terms of x.

$40 = (2x+10)+(3x-5)$

We can now solve for x.

$40-10+5= 2x+3x$

$35=5x$

Dividing by 5.

$7=x$

$AB=40$

$AC=2(7)+10$

$AC=14+10$

$AC=24$

$BC=3(7)-5$

$BC=21-5$

$BC=16$

. Using ratios and the Pythagorean Theorem the approximate width is 23.5 inches and the height is inches.

Sergio039 [100]

Given:

There is a ratio given as 16:9 of width to height and diagonal is 27 iniches

Required:

We need to find the value of height

Explanation:

By ratio

$\begin{gathered} \frac{w}{h}=\frac{16}{9} \\ \\ h=\frac{9}{16}w \end{gathered}$

where w is width and h is height

by using pythagorean theorem

$\begin{gathered} 27^2=h^2+w^2 \\ 729=\frac{81}{256}w^2+w^2 \\ \\ 186624=81w^2+256w^2 \\ w^2=553.78 \\ w=23.5\text{ in} \end{gathered}$

to find h

$h=\frac{9}{16}*23.5=13.24\text{ in}$

Final answer:

height is 13.24 inches
