Answer:

Step-by-step explanation:

$\text{If}\ \overrightarrow{BD}\ \text{is the angle bisector of}\ \angle ABC,\ \text{then we have two equations:}\\\\(1)\qquad2x+y=14+y\\(2)\qquad5x-y=x+13y\\------------------\\\\(1)\\2x+y=14+y\qquad\text{subtract}\ y\ \text{from both sides}\\2x=14\qquad\text{divide both sides by 2}\\\boxed{x=7}\\\\\text{Put the value of x to (2):}\\\\5(7)-y=7+13y\\35-y=7+13y\qquad\text{subtract 35 from both sides}\\-y=-28+13y\qquad\text{subtract 13y from both sides}\\-14y=-28\qquad\text{divide both sides by (-14)}\\\boxed{y=2}$

Answer:

(86.2,0) is the x-intercept.

Step-by-step explanation:

You can use the slope formula to figure this one out:

Just use two of the points on the table, any of them will work:

$(33,-22)\\(52,-33)$

$\frac{-22-33}{33-52} =\frac{-55}{-19}=\frac{55}{19}$

Now you have the slope of the equation, now using the y-intercept equation you can substitute the variables for point of the table and the new slope.:

$(71,-44)\\y=mx+b\\-44=\frac{55}{19} (71)+b$

Now just solve for b to get the y intercept:

$-44=\frac{55}{19}(71)+b\\-44= \frac{3905}{19} +b\\(-\frac{3905}{19})-44=\frac{3905}{19} +b(-\frac{3905}{19})\\ -\frac{4741}{19}=b$

Now you have the y-intercept so you just have to plug in 0 to the y spot and it will calculate the x-intercept.

$0=\frac{55}{19}x-\frac{4741}{19}\\(+\frac{4741}{19})0=\frac{55}{19}x-\frac{4741}{19}(+\frac{4741}{19})\\\\\frac{4741}{19}=\frac{55}{19}x\\\frac{\frac{4741}{19}}{\frac{55}{19} }= \frac{\frac{55}{19} x}{\frac{55}{19} } \\\frac{431}{5} =x\\or\\86.2=x$

And that's the x-intercept.

A and B are complementary angles. If A = (x – 23)° and m

Lana71 [14]

Answer:

∠ B = 85°

Step-by-step explanation:

Complementary angles sum to 90° , then

x - 23 + 2x + 29 = 90 , that is

3x + 6 = 90 ( subtract 6 from both sides )

3x = 84 ( divide both sides by 3 )

x = 28

Then

∠ B = 2x + 29 = 2(28) + 29 = 56 + 29 = 85°

A 24 inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece

Anastaziya [24]

F=length of first piece=x; S=length of second piece=2x

T=length of third piece=3x

F+S+T=24 inches

x+2x+3x=24 inches

6x=24in

F=x=4in

ANSWER 1: The length of the first piece is 4 inches.

S=2x=2(4in)=8in

ANSWER 2: The length of the second piece is 8 inches.

T=3x=3(4in)=12 inches.

ANSWER 3: The length of the third piece is 12 inches.

CHECK:

F+S+T=24in

4in+8in+12in=24in

24in=24in
