Make a the subject of the formulae<br><br> 5c = 3b(6a + 2)

Alexus [3.1K]

Answer:

$a = \frac{5c-6b}{18b}$

Step-by-step explanation:

$5c = 3b(6a + 2)$

$\frac{5c}{3b} = (6a + 2)$

$\frac{5c}{3b}-2 = 6a$

$\frac{5c-6b}{3b} = 6a$

$\frac{5c-6b}{18b} = a$

In the xy-coordinate plane shown, line L passes through point C and has a slope of -2. A dilation of line {with center A and a s

masya89 [10]

Answer:

C' (-4 , 2)

slope of new line = line "L" = -2

Step-by-step explanation:

C (x₀,y₀): (0,2) dilation center (h,k): (2,2) scale factor (sf): 3

C' (x,y)

x = 2 + 3*(0-2) = -4 x = h + sf*(x₀ - h)

y = 2 + 3*(2-2) = 2 y = k + sf*(y₀ - k)

C' (-4 , 2)

slope of new line = line "L" = -2

- Three people examine the system of linear equations shown.

Makovka662 [10]

Answer:

there are no solutions as the two straight lines represented by the two equations are parallel, so they have no point in common

Step-by-step explanation:

general equation of a straight line: ax + by + c = 0

the slope (or raise) of a straight line m is equal to -a/b (b=1 a=-2 in this exercise as the equation is 1y=-2x - 4)

so m1 = -2/1 = -1/2

and m2 = -2/1 = -1/2

there is also a geometrical explanation, but I am not sure if it could be too complex

Find the slope of the line passing through the pairs of points. (-11. - 11) and (10,- 1)

Fittoniya [83]

Answer:

the slope is $\frac{10}{21}$

Step-by-step explanation:

slope formula for linear equations:

$\frac{y_2 - y_1}{x_2 - x_1}$ so for the two points $\frac{-1 - (-11)}{10 - (-11)}$ $= \frac{10}{21}$
