Which steps should be used to graph the equation below? y-4=1/3(x+2)

juin [17]

-> First, we want to put it into more of a slope-intercept form so we can graph.

y - 4 = 1/3 (x + 2)

y = 1/3 (x + 2) + 4

y = 1/3x + 2/3 + 4

y = 1/3x + 14/3

-> Next, we will plot the point (0, 14/3) because it is the y-intercept of our equation

-> Last, we will move up one and to the right three, following the pattern of "rise over run" with our slope of 1/3

[] The finished graph is attached

[] I have also graphed the original equation to show that they overlap, showing that our simplification works

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

If, triangle ABC, the measure of angle B is greater than 90 degrees, and AB=BC, what is a possible measure for angle C in degree

sasho [114]

Answer:

Step-by-step explanation:

Let us start with B = 90

That would mean that each of the other 2 angles must add to 90 which makes each of them 45.

But the question doesn't allow that. B has to be greater than 90 which means that the other two angles must be less that 45 each.

the only answer that does that is A

A circle has a diameter of 10 centimeters. of a sector with a central angle of 50 degrees is cut out, what is the area of this s

kramer

Answer:

D. 10.91 square centimeters

Step-by-step explanation:

Area of a sector of a circle = $\frac{\theta}{360}\\$ $\pi$ $r^{2}$

where $\theta = 50^{o} C$

radius (r) = half of diameter = 10/2 = 5 cm

Area = $\frac{50}{360} * \frac{22}{7} * 5^{2}$

= 10.91 $cm^{2}$
