We are given with the expression <span>4y - 7x = 0. this is equal to 4y = 7x or y = 7/4 x. In this case, y is directly proportional to x where the constant of proportionality is equal to 7/4. When x increases, the value of y also increases, and vice versa.</span>
Answer:
s = 21.16
Step-by-step explanation:
0.5s +1= 7+ 4.58
Combine like terms
0.5s +1=11.58
Subtract 1 from each side
0.5s +1-1= 11.58-1
.5s = 10.58
Multiply by 2
.5s *2 = 10.58*2
s = 21.16
To find the vertex we need to represent quadratic function in vertex form.
<span>f(x)=(x-8)(x-2)
</span>f(x)=x²-8x-2x+16=x²-10x+16
f(x)= x²-2*5x+25-25+16= (x-5)² - 9
f(x)= (x-5)² - 9
Vertex is going to be (5, - 9)
Answer:
height: 7 in
base: 14 in
Step-by-step explanation:
Let the height of the triangle equal x. This means that the base can be represented by the expression 2x. Now we plug these values into the area formula for a triangle:
A = bh / 2
49 = x * 2x / 2
And simplify
49 = x^2
We can find the square root of both sides to get x = 7, so the height is 7 inches. Since the base is twice the height, it is 14 inches.
