Slope-intercept form: y = mx + b [m is the slope, b is the y-intercept, or the y value when x = 0 ---> (0, y)]

To find the equation's y-intercepts, you can rearrange the variables, and isolate/get y by itself

#1

cx + ay = b     Subtract cx on both sides

ay = b - cx        Divide a on both sides

y=\frac{b}{a}-\frac{c}{a}x    (0, \frac{b}{a}) is your answer

Do the same for the rest, and you should get:

#2 (0, \frac{a}{b})

#3 (0, \frac{c}{b})

#4 (0, \frac{c}{a})

For the given function, identify the x- and y-intercepts if any, the vertex, the axis of symmetry, and the maximum or minimum va
motikmotik

Answer:

B) The x-intercepts are (−5,0) and (5,0). The y-intercept is (0,25). The vertex is (0,25). The axis of symmetry is x=0. The maximum value of the function is 25.

Step-by-step explanation:

Given that the function is:

y=f(x)=-x^2+25

It is quadratic equation, therefore we can observe that it is a parabola.

The coefficient of x^{2} is negative, therefore it opens downwards.

That means <em>it will have a maximum value.</em>

This maximum value is at the vertex and where x = 0.

Also, vertex is at x intercept.

x intercept is the value of x where we have y = 0 and

y intercept is the value of y where we have x = 0

So, let us put y = 0 first.

0=-x^2+25\\ \Rightarrow x^{2} =25\\\Rightarrow x =5, -5

Therefore x intercepts are at (5, 0) and (-5, 0)

Now, let us put x = 0,

y=0+25\\\Rightarrow y =25

Therefore y intercept is at (0, 25).

It is the point of maximum value (which is 25) and vertex of parabola as explained above.

Kindly refer to the attached image for the graph of given function.

Therefore, correct option is:

B) The x-intercepts are (−5,0) and (5,0). The y-intercept is (0,25). The vertex is (0,25). The axis of symmetry is x=0. The maximum value of the function is 25.

True or False? The circumcenter of a triangle is the center of the only circle
larisa [96]

Answer:

The statement is False

Step-by-step explanation:

we know that          

An <u>inscribed circle</u> is the largest circle contained within the triangle. The center of the circle inscribed in a triangle is the incenter of the triangle.

The incenter is the point where the angle bisectors of the triangle intersect.

The <u>circumscribed circle</u> is the circle that passes through all three vertices of the triangle. The center of the circumscribed circle is called the <u>circumcenter</u> of the triangle

The circumcenter is the point where the perpendicular bisectors of the sides intersect.

therefore

The circumcenter of a triangle is the center of the only circle

that can be circumscribed about it.

The statement is false

Amanda is placing an order for running shoes and leather boots for her footwear boutique. She needs a total of 48 pairs of shoes
Basile [38]

Constraint 1:

Let the total number of running shoes be = R

Let the total number of leather boots be = L

As the given number of total shoes are 48,

The equations becomes,

R + L = 48............(1)

Constraint 2:

As running shoes are twice the leather boots, equation becomes,

R = 2L..............(2)

Putting the value of R from equation(2) in equation (1)

2L+ L=48

3L=48

L=16

Now putting the value of L in equation(2)

R= 2L

R = 2*16

R=32

Hence, Amanda needs 16 pairs of leather boots and 32 pairs of running shoes.
