Answer:

c- 75

p- 25

Step-by-step explanation:

so haley has 2450 in total and the pig cost 25 so if the cows are 3 times more than the pigs . so the cows stuff cost 75 each so now multiply 75 x 30 = 2250 and the pigs cost 25 each multiply 25 x 8 = 200 then add 2250 + 200 = 2450 which means haley has the exact money to pay the stuff. haley spends 75 on each cow.

The graphs below have the same shape. what is the equation o the red graph?

maw [93]

So the equation of the red graph is already given to us: $f(x) = x^2$ . I assume you meant the blue graph?

We can use the vertex form: $y = a(x - h)^2+ k$ , where $(h,k)$ is the vertex. (We can ignore $a$ because $a$ is 1 for this graph.) Remember that the vertex is the maximum or minimum of a parabola and the point that the line of symmetry passes through. For f(x) the vertex is (0,0).

The vertex for $g(x)$ is at $(-4, -2)$ on the coordinate plane. (4 left, 2 down)

Plug into the vertex form:

$y = (x - (-4))^2 -2$

The double negative becomes a positive, and then you're done:

$y = (x + 4)^2-2$

The equation of circle having a diameter with endpoints (-2, 1) and (6, 7) is

densk [106]

Answer:

$(x-2)^{2}+(y-4)^{2}=25$

Step-by-step explanation:

step 1

Find the diameter of the circle

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(-2,1)\\B(6,7)$

substitute the values

$d=\sqrt{(7-1)^{2}+(6+2)^{2}}$

$d=\sqrt{(6)^{2}+(8)^{2}}$

$d=\sqrt{100}$

$d=10\ units$

The radius is half the diameter

$r=10/2=5\ units$

step 2

Find the center of the circle

the center of the circle is the midpoint between the endpoints of the diameter

The center is

$(\frac{-2+6}{2},\frac{1+7}{2})$

$(2,4)$

step 3

Find the equation of the circle

The equation of the circle is

$(x-h)^{2}+(y-k)^{2}=r^{2}$

substitute the values

$(x-2)^{2}+(y-4)^{2}=5^{2}$

$(x-2)^{2}+(y-4)^{2}=25$

What is the answer I need help

Fudgin [204]

Answer:

The area of the figure is 36.

Step-by-step explanation:

The area formula for both sections of the figure is $A = bh$ . In both sections, the base is 6 and the height is 3. 6 times 3 is 18, and 18 times 2 is 36.

*For more information on the formula, look up the formula for parallelograms, and also I hope you understand the side length with two tick marks is not relevant to finding the area*

Find an ordered pair x-2y=4

Vesnalui [34]

Answer:

Step by Step:
x-2y=4
+2y +2y
x=-2y+4

x-2y=4
-4 -4
x-2y-4=0
+2y +2y
x-4=2y
Divid by 2
1/2x-2= y

x=-2y+4
x=-2(1/2x-2)+4
x=-x+4+4
x=-x+8
+x +x
2x= 8
x=4

y=1/2x-2
y=1/2(4)-2
y=2-2
y=0
(4,0)
