You have to split the -x into 2 numbers that multiply to the same product as the two outside numbers so x^2+3x-4x-12
then split it and factor x(x+3)-4(x+3)
then you get (x-4)(x+3)
Answer:
x=65/14
Step-by-step explanation:
(x-10)/(x-4)=50/-6
-50/6=-25/3
(x-10)/(x-4)=-25/3
x-10=-25/3(x-4)
x-10=-25/3x+100/3
x-(-25/3x)=100/3+10
x+25/3x=130/3
28/3x=130/3
x=(130/3)/(28/3)
x=(130/3)(3/28)
x=130/28
x=65/14
Both triangles are similar. The area of the smaller triangle is about 270 ft2. Which is the best approximation for the area of the larger triangle? small traingle side is 25ft the bigger traingle side is 35ft.
We know the relation between the area of similar triangles and the side length
=
area of the smaller triangle= 270 ft2
Let the area of bigger triangle =x
small traingle side=25ft
the bigger triangle side = 35ft
Ratio of sides is 25 : 35 that is 5:7
Now we make a proportion
=
270/x = 25/49
Cross multiply it
270 * 49 = 25 * x
13230 = 25x
divide by 25 on both sides
So x= 529.2
Area of larger triangle is approximately 530 square feet.
<h3>
Answer: Yes it is a function</h3>
===============================================
Here are some reasons why
- We can solve x+2y = 7 for y to get y = -0.5x+3.5; this equation is in slope intercept form y = mx+b. All equations in the form y = mx+b are linear and also a function.
- For any input x, there is exactly only one y value that pairs with it.
- The vertical line test can be used to effectively verify item #2 above. The idea is that it is impossible to draw a vertical line through more than one point on the graph. So it is said to pass the vertical line test.
Answer:
1/2 or 50%
Step-by-step explanation:
I think its asking what is the odds landing on the white
so number of white places over total of spaces you could land on
6/12 = reduce 1/2
