CAN SOMEONE PLEASE HELP ME!!!!

I have this point: (-1,2) and my slope is undefined. How would I write my equation in point-slope form: y - y^1 = m (x -x^1)? Th

Answer:

x = -1

Step-by-step explanation:

Given the point, (-1, 2), and that the slope is undefined.

The standard linear equation of vertical lines is x = a, where the x-intercept is (a, 0), and the slope is undefined because all points on the line have the same x-coordinate. Attempting to solve for the slope of a vertical line using the slope formula, m = (y₂ - y₁)/(x₂ - x₁), will result in a mathematical operation of division by zero (which is an undefined operation).

Since the slope is undefined, then it is not possible to create a linear equation in either the slope-intercept form, or point-slope form.

Therefore, the equation of a vertical line given the point, (-1, 2) is x = -1.

Find the slope and y-intercept of the line through the points (-3,-4) and (0,-1)

Alja [10]

Answer:

Slope=1, y-intercept=-1.

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-(-4))/(0-(-3))

m=(-1+4)/(0+3)

m=3/3

m=1

y-(-4)=1(x-(-3))

y+4=x+3

y=x+3-4

y=x-1

y=mx+b where m=slope and b=y-intercept

so you have slope of 1 and y-intercept of -1

"at the end of the year Juan has $52.71 more than 4 times his balance at the beginning of the year if his ending balance was $17

Salsk061 [2.6K]

At the end of the year, Juan has 52.71 more than 4 times his balance at the beginning. Okay, let's set this up.

4x + 52.71
(4 times) (52.71 more)
His ending was 172.90, so
4x + 52.71=172.90
4x= 120.19
x= 30.05
He had $30.05 at the beginning of the year.

Plzz look into the question in the attachements

iren2701 [21]

Given : Diameter of the right circular cone ==> 8 cm

It means : The Radius of the right circular cone is 4 cm (as Radius is half of the Diameter)

Given : Volume of the right circular cone ==> 48π cm³

We know that :

$\bigstar \ \ \boxed{\textsf{Volume of a right circular cone is given by : $\pi r^2\dfrac{h}{3}$}}$

where : r is the radius of the circular cross-section.

h is the height of the right circular cone.

Substituting the respective values in the formula, we get :

$\mathsf{\implies \pi \times (4)^2 \times \dfrac{h}{3} = 48\pi}$

$\mathsf{\implies 16 \times \dfrac{h}{3} = 48}$

$\mathsf{\implies \dfrac{h}{3} = 3}$

$\implies \boxed{\mathsf{h= 9 \ cm}}$

Answer : Height of the given right circular cone is 9 cm

Find the size of each interior angle of a regular hexagon

Serhud [2]

Answer:

Each interior angle = 180° -60° = 120°

Step-by-step explanation: We know that the three angles in a triangle, add up to 180°, and all the three angles are 60° in an equilateral triangle. The total number of angles of an enclosed space is 180° (n-2) where in is the number of sides.
A hexagon has six sides, so: s= 180° (6-2)

s= 180° x 4

s= 720°

now since in a regular shape, each interior angle is equal. We just divide the total interior angle with a number of sides

6.

720° divided by 6 is equal to 120°
