Y-1=0 is what form:<br> Standard<br> Point-Slope Form<br> Brainliest for first Answer

hammer [34]

This would be point-slope form.

Slope-intercept form is in the form: y = mx + b

Standard is in the form ax + by = c

Point-slope form is in the form y - y.1 =m(x - x.1)

The form this most closely resembles is point-slope.

Tell whether the triangle with the given side lengths is a right triangle.<br> 10in., 24in., 26in.

ra1l [238]

Answer- Yes it is a right triangle.
You can use the Pythagorean Theorem.
( a^2 + b^ = c^2 ) and replace a with 10, b with 24, and c with 26 and the equation will be balanced on both sides.

(10^2 + 24^2 = 26^2)
(100 + 576 = 676 )

A circle is centered at the origin and contains the point (-6, -8). What is the area of this circle?

gogolik [260]

Answer:

314 units²

Step-by-step explanation:

Centre of the circle = (0, 0)

Another point on the circle = (-6, -8)

$\text {Radius = }\sqrt{(0 - (-6))^2 + (0- (-8))^2}$

$\text {Radius = }\sqrt{6^2 + 8^2}$

$\text {Radius = }\sqrt{100}$

$\text {Radius = }10$

Area = π (10)² = 100π = 314 units²

Find x. (Finding an angle measure given extended triangles) Please help

Alja [10]

50+79=129
180-129=51
X=51

Explanations
Angles on a straight line add up to 180 degrees. So 180-101=79 degrees
50 degrees is an opposite angle so it moves into the internal angle.
Angles in a triangle add up to 180 so (180-50-79=51)
Ans is 51 I think

The linear function graphed below represents Brenda’s monthly cell phone bill based on the number of hours she uses. What is her

grigory [225]

Answer:

$12 per hour

Step-by-step explanation:

In order to find her hourly rate we have to find the amount of dollars billed per hour. To do this we can use this expression: $\frac{y2 - y1}{x2 - x1}$

Let's use the points (1, 27) and (2, 39) in the expression:

$\frac{39 - 27}{2 -1}$

Now let's simplify the expression:

39 - 27 = 12

2 - 1 = 1

The expression simplifies to 12/1, or 12. This means that Brenda is billed $12 every hour she uses her phone.

I hope this helps :)
