Answer:

$\Huge \boxed{x=0}$

Step-by-step explanation:

Angles on a straight line add up to 180 degrees.

y + 50 = 180

y = 180 - 50 = 130

We can use Angle formed by a chord and tangent theorem to solve for x.

The angle formed by a chord and tangent is half the measure of the intercepted arc.

130 = 1/2(2x+260)

Expand brackets.

130 = x+130

Subtract 130 from both sides.

x = 0

Hello there!

Math is hard! So we as students, we need to play the smart game with Math in order to find the easiest way to solve the problems. What do I mean? Well as you can see they gave us Fraction which won't be easy! So we will transform the fractions into decimals. So let's get started.

Then a scale of 1/4. Transformed into decimal = Then a scale of 0.25
So instead of using the fraction 1/4, I used its decimal 0.25

So if:

48 feet ......> 12 inches
x feet ........> 0.25 inches

Cross multiply

12 * x = 0.25 * 48

12x = 12
Divide both sides by 12
12x/12 = 12/12

x = 1

The correct answer is option D, 1 foot

I hope this helps! Please let me know if you have any question.

Thanks!

Write an equation in slope-intercept form of the line that passes through the given point and is

Tema [17]

Answer:

y = 9x - 15

Step-by-step explanation:

The given y = 9x - 5 is already in slope-intercept form. Any line parallel to this one has an equation that looks exactly the same except for the constant term. Call the new constant term 'C.'

Start with y = 9x - 5 and substitute the coordinates of the given point (-1, 6):

6 = 9(-1) + C, or

6 + 9 = C, or

C = 15

Then the equation of the line that passes through (-1, 6) and is parallel to y = 9x - 5 is

y = 9x - 15
