Answer:

26

Step-by-step explanation:

complementary means two angles that add up to 90 degrees

90-38=52

52÷2=26

to check work you can do 26×2 (since there's 2x) = 52

52+38=90

A rectangular garden's length is 5 feet longer than its width. If its perimeter can be represented using the function P(x) = 4x
Ainat [17]
Let
y----------> the length of the rectangle
x---------> the width of the rectangle
P--------> perimeter of a rectangle

we know that
P=38 ft
[P]=2*[x+y]------> 38=2*[x+y]------> equation 1
y=5+x-------> equation 2
<span>substitute 2 in 1
</span>P=2*[x+(5+x)]---------> P=4x+10---------> the given equation
4x=38-10--------> 4x=28----> x=7 ft
y=5+7-----> y=5+7------> y=12 ft

the answer is
the width is 7 ft

Answer:

  D  (7, 0.5)

Step-by-step explanation:

The equations must be interpreted to be ...

  • y = -1/2x +4
  • y = 1/2x -3

A graph shows the solution to be (7, 0.5), matching selection D.

___

You can add the two equations together to get ...

  (y) +(y) = (-1/2x +4) + (1/2x -3)

  2y = 1 . . . . . simplify

  y = 1/2 . . . . .divide by 2

It can be convenient to use the second equation to find x.

  1/2 = 1/2x - 3

  1 = x - 6 . . . . . . multiply by 2

  7 = x . . . . . . . . . add 6

The solution is (x, y) = (7, 0.5). . . . . matches selection D.

Write in standard form an equation of the line passing through the given point with the given slope.
Contact [7]

Answer:

Opt B.

Step-by-step explanation:

Remember that the equation of a line tells us that y=mx+b, where m is the slope (Which we have and is -8), just need to find b, for that, lets eval the given point (1,-5) in the above equation.

-5=-8*1+b

Where we obtain that b=3

Our line is written as y=-8x+3

And in standard form that would be (grouping variables in the same side of equality sign)

y+8x=3
