so it would be 8x13/8+13, which would simplify out to be 104/8+13 which would then simplify out even more to be 104/21 as a fraction or 4.95 as a decimal
hope this helps!! :) ❤❤❤❤
Answer:
Part 1)
Part 2)
Part 3)
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form or
Part 1) y varies inversely with x. If y = 8 and k (the constant of variation) = 19, what is x?
we know that
substitute the given values and solve for x
Part 2) y varies inversely with x, and k (the constant of variation) = 23. What is the value of y when x = 7?
we know that
substitute the given values and solve for y
Part 3) y varies inversely with x. When y = 6.7, x = 1. What is the value of k, the constant of inverse variation?
we know that
substitute the given values and solve for k
B. (x-5) is a factor.
<u>Step-by-step explanation:</u>
To find out the relationship among the factor and an expression, we have to factorise it as,
2x² - 7x - 15
Here, sum = coeff. of x = -7
Product = constant × coeff of x² = -15 × 2 = -30
Now we have to find 2 numbers, which satisfies the above 2 conditions are -10 and 3.
-10 +3 = -7
-10× 3 = -30
2x² - 7x - 15
= 2x²- 10x + 3x - 15
Taking common terms as,
= 2x(x-5) +3(x - 5)
= (2x+3) (x-5)
So the expression is factorized and (x-5) is one of the factors of the expression.
