Solve for the given variable 7x+5y=6 for y

olga_2 [115]

Answer:

y = (6/5) - (7/5) x

Step-by-step explanation:

goal: to rearrange the equation such that it takes the form:

y = f(x) ; where f(x) is an expression in terms of x

Given:

7x+5y=6 subtract 7x from both sides

5y = 6 - 7x (divide both sides by 5)

y = (6-7x) / 5

y = (6/5) - (7/5) x

The roots of $3x^2 - 4x + 15 = 0$ are the same as the roots of $x^2 + bx + c = 0,$ for some constants $b$ and $c.$ Find the orde

Akimi4 [234]

we are given

quadratic equation as

$3x^2-4x+15=0$

now, we can find b and c from

$x^2+bx+c=0$

we can see that coefficient of x^2 is 1

so, we will have to make coefficient x^2 as 1

so, we divide both sides by 3

$3x^2-4x+15=0$

$\frac{3x^2-4x+15}{3}= \frac{0}{3}$

$\frac{3x^2}{3}-\frac{4x}{3}+\frac{15}{3}= \frac{0}{3}$

now, we can simplify it

$x^2-\frac{4}{3}x+5= 0$

now, we can compare it with

$x^2+bx+c=0$

we get

$b=-\frac{4}{3}$

$c=5$

so, we get order pair as

$(b,c)=(-\frac{4}{3} , 5)$ ..............Answer

Bond [772]

Answer:

Step-by-step explanation:

We can notice that based on the given pattern, the average rate of change from $x=n$ to $x=n+1$ , where $n \in \mathbb{Z}$ , is $-2n-1$ .

So, the average rate of change from $x=8$ to $x=9$ is $-2(8)-1=-17$ .
