help pls i don’t know it!!!!

Answer:

(x-3)(x+5) = 0

x-3 = 0 and x+5=0

x=3 and x=-5 when y=0

y = x^2+2x-15

complete the square

= x^2+2x + 1 -15 - 1

= (x+1)^2 -16

f(x) = y = (x+1)^2 -16

y intercept = -15 or the point (0,-15)

x intercepts = 3 and -5 = the two zeroes or roots, or the points (3,0) and (-5,0)

vertex or minimum point of the upward opening parabola is (-1,-16)

note the 2 zeroes are both 4 units horizontally from the vertex x value, 3 to -1 is 4, and -1 to -5 is 4.

the line of symmetry is x=-1. left and right of x=-1 are mirror images

x = -1

Step-by-step explanation:

2(x - 1) + 4 = -(x + 6) + 5

2x - 2 + 4 = -x - 6 + 5

2x + 2 = -x - 1

2x + x = -1 - 2

The value to be added to both sides of the equation to make the left side a perfect square trinomial is; -36.

To make the equation x2 – 12x = 1 look similar to the completing the square kind of expression where the left hand side of the equation becomes a perfect square, we must do the following;

In this scenario, the term (x² - 12x) can be rewritten as; (x - 6)² - 36.

This so because the expansion of (x - 6)² becomes;

Therefore, there's a need to subtract 36 from both sides of the equation so that the equation x2 – 12x = 1 is retained.

Therefore, the value to be added to both sides of the equation to make the left side a perfect square trinomial is; -36.

The answer is C (-3 , -3) and (-3 , 3)

Step-by-step explanation:

the other answer was already right.

yes, C (-3, -3) and (-3, 3)

but why ?

the slope is the y/x ratio of the x and y coordinate differences when going from one point to the other.

so, x changes 0 units. y changes 6 units (from -3 to 3).

so, the slope is 6/0 = infinite or simply undefined.

this is a vertical line at x = -3.

Answer:

[tex]f(x)=3x-10[/tex]

Step-by-step explanation:

Recall point-slope form: Given a point [tex](x_{1}, y_{1})[/tex] and the slope [tex]m[/tex], the equation for the line is [tex]y-y_{1}=m(x-x_{1})[/tex].

We can plug in for our point and slope!

The equation for the line is [tex]y-14=3(x-8)[/tex].

Distributing the right side gives [tex]y-14=3x-24[/tex].

Adding [tex]14[/tex] to both sides gives [tex]y=3x-10[/tex].

So, the function is [tex]\boxed{f(x)=3x-10}[/tex] and we're done!

Step-by-step explanation:

x = price of pants

y = price of top

x + y = 36

x = (4/5)y

we use the second equation as substitute in the first

(4/5)y + y = 36

4y + 5y = 180

9y = 180

y = $20

x = (4/5)y = (4/5)×20 = 4×4 = $16

The waves will cover a circular area of 7542.96 miles.

The circle is defined as the locus of the point traces around a fixed point called the center and is equidistant from the outer trace. The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.

Given that a radio station sends out radio waves in all directions from a tower at the center of the circle of broadcast range. The circle has a diameter of ​98 miles.

The area of a circle is calculated by the formula below:-

Area = ( π / 4 ) d²

Area = ( π / 4 ) ( 98 )²

Area = 7542.96 square miles

Therefore, the waves will cover a circular area of 7542.96 miles.
