Answer:

y = 13.9

Step-by-step explanation:

The triangle is a 30-60-90 triangle, so x is 16 (double 8). Use the pythagorean theorum to find y. 256 - 64 =192. $\sqrt{192}$ is about 13.9

The equation of line EF is y = 2x + 1. Write an equation of a line parallel to line EF in slope-intercept form that contains poi

Answer: The answer is (b) $y=2x+2.$

Step-by-step explanation: The equation of a straight line in slope-intercept form is given by

$y=mx+c,$ where, 'm' is the slope and 'c' is the y-intercept of the straight line.

The equation of the given line EF is

$y=2x+1.$

Here, slope, m=2 and y-intercept, c=1.

Since our new line is parallel to the given line, so the slope of the new line=m=2.

So, let the equation of the new line be

$y=mx+d\\\\\Rightarrow y=2x+d.$

Now, since the line passes through the point (0,2), so

$2=2\times 0+d\\\Rightarrow d=2.$

Thus, the equation of the new line parallel to line EF will be

$y=2x+2.$

The correct option is (b).

Find the length of the line joining the points A(-2,10) and B(-8,2)

Vesnalui [34]

Length of the line

= $\sqrt{((-2)-(-8))^{2}+(10-2)^{2} }$

= $\sqrt{36+64}$

= $\sqrt{100}$

= 10

What is 1 5/8 +4 7/8 show work

Anon25 [30]

Take the mixed number apart and have a whole number and a fraction
1+4 and 5/8 + 7/8
1+4=5
5/8 + 7/8 = 12/8
12/8 = 1 4/8
Add 5 to 1 4/8
5 + 1 4/8 = 6 4/8
1 5/8 + 4 7/8 = 6 4/8
In simplest term, the answer is also 6 1/2
-------------------------------------------------
Another way to solve it is by turning both 1 5/8 and 4 7/8 into improper fractions.
1 5/8 = 13/8
4 7/8 = 39/8
Add them.
13/8 + 39/8 = 52/8
Turn 52/8 into a mixed number.
52/8 = 6 4/8
Simplify it to get 6 1/2.
