Given the point (3,4) and the slope of 6, find Y when X =27

1 answer:

4 0

1) we find out the equation of the line.
Given a point (x₀,y₀) and the slope m, the slope-point form is:

y-y₀=m(x-x₀)

Data:
(3,4)
m=6

Therefore:

y-4=6(x-3)
y-4=6x-18
y=6x-18+4
y=6x-14

2) we find out y, when x=27
y=6*(27)-14
y=162-14
y=148

Answer: When x=27, then y=148.

From the sum of 4a + b + c and 9a - c subtract the sum of 18a - b - c and 14a - 2b - c

sergiy2304 [10]

1:-

$\\ \rm\Rrightarrow 4a+b+c+9a-c$

$\\ \rm\Rrightarrow 4a+9a+b+c-c$

$\\ \rm\Rrightarrow 13a+b$

2:-

$\\ \rm\Rrightarrow 18a-b-c-(14a-2b-c)$

$\\ \rm\Rrightarrow 18a-b-c-14a+2b+c$

$\\ \rm\Rrightarrow 18a-14a-b+2b-c+c$

$\\ \rm\Rrightarrow 4a+b$

We can use quadratic formula to determine the roots of the given quadratic equation.

The quadratic formula is:

$x= \frac{-b+- \sqrt{ b^{2} -4ac} }{2a}$

b = coefficient of x term = -11
a = coefficient of squared term = 2
c = constant term = 15

Using the values, we get:
$x= \frac{11+- \sqrt{121-4(2)(15)} }{2(2)} \\ \\ 
x= \frac{11+-1}{4} \\ \\ 
x=3, x= 2.5$

So, the correct answer to this question are option B and D
