Find the equation of the line that passes through (4,4) and is parallel to y=2x+4. Leave your answer in the form​
Bess [88]

Answer:

y=2x-4

Step-by-step explanation:

If a line is parallel to another line, the only thing that's different in the equation is the y-intercept. Therefore we can solve for the y-intercept using the point (4,4)...

Note that the slope-intercept equation is y=mx+b where b is the y-intercept and m is the slope. x and y are the x and y coordinate pairs.

y=2x+b

4=2(4)+b

4=8+b

b=-4

Therefore the equation of the line that is parallel to y=2x+4 and passes through (4,4) is...

y=2x-4

What is the area of the composite figure?
Ray Of Light [21]

Answer:


Step-by-step explanation:

The figure is made up of a square with side 4 cm and 3 semicircles of radius 2 cm.

A = area of square + area of 3 semicircles

A = (4 cm)^2 + 3 * (1/2) pi * (2 cm)^2

A = 16 cm^2 + (1/2) 12pi cm^2

A = (6pi + 16) cm^2

What is 7(34-99)-7+2 7/9
allsm [11]

Answer:

-459 2/9

Step-by-step explanation:

calculate 34-99= -65

and turn 2 7/9 into a mixed number as 25/9

leaves u with

7(-65)-7+25/9

multiply 7x-65=-455

-455-7+25/9

-462+25/9

get common denomionator and add

-4133/9 or -459 2/9 or -459.2

Which three pairs of side lengths are possible measurements for the triangle?
katrin2010 [14]

Answer:

AB = 6, BC = 6

AB = 4, AC = 4√2

BC = 2√2, AC = 4

Step-by-step explanation:

The sides of an isosceles right triangle are in the ratio 1:1:√2 where √2 is the hypotenuse.

So if, for example, BC = 2√2, then AC = 2√2 * √2 = 4.
