Answer:

Step-by-step explanation:

1. 56 + 81 = 137

2. The exterior angle theorem means that the 2 angles within a triangle that is on the opposite side of the angle outside the triangle could be added to find the angle that is outside of the triangle.

3. 56 and 81 are on the opposite side of the "x" outside the triangle which means that they could be added together which equals 137 degrees.

Hope this helps!

Answer: B. y = 1/2x - 1

Explanation:
I know someone else already answered, but I wanted to explain why the answer is B.

Consider an equation of a line in slope-intercept form: y = mx + b

Since the line intersects the y-axis at -1, that’s the y intercept, or b. We know the slope of the line is positive because it slopes upward from left to right. From each whole number solution point, the line goes up one and two to the right. Slope, represented by m, is “rise” over “run”, or the change in y over the change in x. This makes the slope 1/2.

I hope this helps.

21x-5=7+17x Write it down step by step please

Nat2105 [25]

Answer: x=3

Step-by-step explanation: Step 1: Simplify both sides of the equation.

21x−5=7+17x

21x+−5=7+17x

21x−5=17x+7

Step 2: Subtract 17x from both sides.

21x−5−17x=17x+7−17x

4x−5=7

Step 3: Add 5 to both sides.

4x−5+5=7+5

4x=12

Step 4: Divide both sides by 4.

$\frac{4x}{4}$ = $\frac{12}{4}$

So Final Answer: x=3

In circle O, AP = √10, PB = x and BC = 3. Find the value of x.

Artyom0805 [142]

Answer:

The value of x is $2\ units$

Step-by-step explanation:

we know that

Applying the tangent-secant theorem

$AP^{2}=PB*PC$

substitute the values and solve for x

$\sqrt{10}^{2}=x*(x+3)$

$10=x^{2}+3x$

$x^{2}+3x-10=0$

using a graphing tool

to solve the quadratic equation

The solution is $x=2\ units$

see the attached figure

Ed’s rental charges a flat fee of $5 plus $2 per hour to rent a pair of skates.

zavuch27 [327]

Flat doesn't change
2 changes with x
y=2x+5
yint is 5

to graph
start at center and go 5 up, that is y intercept
go 1 right and 2 up, that is another point

y=2(2)+5
y=4+5
y=9
cost $9 to rent for 2 hours
