Multiply the whole equation by 4 to cancel out the fractions.
<span>(2r = 5s/2 - s/4)*4
8r = 10s - s
8r = 9s
8r/9 = s
s = 8r/9</span>

Answer:

s=\frac{8r}{9}

Step-by-step explanation:

The given equation is

2r=\frac{5s}{2}-\frac{s}{4}

We need to solve this equation for s.

Simplify the right side of the equation.

Taking LCD on right side of the equation we get

2r=\frac{2(5s)-s}{4}

2r=\frac{10s-s}{4}

2r=\frac{9s}{4}

Multiply both sides by 4.

2r\times 4=\frac{9s}{4}\times 4

8r=9s

Divide both sides by 9.

\frac{8r}{9}=s

Interchange the sides.

s=\frac{8r}{9}

Therefore, the value of s is s=\frac{8r}{9}.

If f(x) is an even function and (6, 8) is one the points on the graph of f(x), which reason explains why (–6, 8) must also be a
ch4aika [34]

Definition: A function is "even" when f(x) = f(−x) for all x.

Geometrically speaking, the graph face of an even function is symmetric with respect to the y-axis, meaning that its graph remains unchanged after reflection about the y-axis.

If point (6, 8) is one the points on the graph of f(x), then f(6)=8 and since function is even, you can state that f(-6)=f(6)=8. This means that point (-6,8) must also be a point on the graph. Geometrically it means that the output of a negative x-value and its opposite is the same.

Answer: correct choice is A.

attashe74 [19]

Answer:

(7x + 5)m

Step-by-step explanation:

area = base  * height = (35x2 + 46x +15) m²

base = (5x + 3)

Using algebraic division, find the height. SEE ATTACHMENT

height = (7x + 5)
