what is the equation in standard form of the line that passes through the point (4,-8) and has a slope of 1/4
Sergio039 [100]
Y = mx + b
slope(m) = 1/4
(4,-8)....x = 4 and y = -8
now sub and find b, the y int
-8 = 1/4(4) + b
-8 = 1 + b
-8 - 1 = b
-9 = b
so ur equation is : y = 1/4x - 9....but we need it in standard form

y = 1/4x - 9
-1/4x + y = -9...multiply everything by -4
x - 4y = 36 <====

What is m in 4/5m=2/9 is it 5/18
Romashka [77]
\frac{4}{5} m =  \frac{2}{9} \\ \\  \frac{4m}{5} =  \frac{2}{9} \\ \\ 4m =  \frac{2}{9} \times 5 \\ \\ 4m =  \frac{10}{9} \\ \\ m =  \frac{10}{9 \times 4} \\ \\ m =  \frac{10}{36} \\ \\ m =  \frac{5}{18} \\ \\

The final result is: m = 5/18 or 0.2778.

If a(x) = 3x + 1 and p(x)= x-4, what is the domain of (b•a)(x)?
Sedbober [7]

Answer:

  all real numbers

Step-by-step explanation:

Both a(x) and b(x) are polynomials. The set of polynomials is closed on multiplication, so (b•a)(x) will also be a polynomial. <em>All</em> polynomials are defined for <em>all real numbers</em>. The domain is the set of input values (x) for which the function is defined.

The domain of (b•a)(x) is all real numbers.

The equation of a parabola is 18(y−5)2=x+3 . What are the coordinates of the focus? (−3, 7) (−5, 5) (−1, 5) (−3, 3)
aleksandrvk [35]
18(y-5)^2=x+3

do the algebra to make it into =x form

x=18y^2-180y+447

then you take the form of the focus, you can do the math
