–3(5 – 15n) = 15(3n – 2)a. 30 b. –15 c. no solution d. all real numbers

1 answer:

6 0

$-3(5-15n) = 15(3n-2)\\-3\cdot5-3\cdot(-15n)=15\cdot3n+15\cdot(-2)\\-15+45n=45n-30\ \ \ |subtract\ 45n\ from\ both\ sides\\\\-15=-30-FALSE\\\\Answer:\fbox{c.\ no\ solution}$

Write the equation of a line Parallel to the given line and passes through points (-4, -3); (2, 3). Hints find the slope by usin

julia-pushkina [17]

First, we obtain the gradient (slope) of the first parallel line

$\text{gradient, m}_1\text{ = }\frac{y_2-y_1}{x_2-x_1}\text{ = }\frac{3-(-3)}{2-(-4)}=\frac{6}{6}\text{ = 1}$

Recall that since both lines are parallel, we have that,

$m_1=m_2$

Thus

$m_2\text{ = 1}$

Hence, we can find the equation of the parallel line given that it passes through the points (-4, -3)

Using

$\begin{gathered} y\text{ = mx + c} \\ \text{where m = m}_2\text{ = 1} \\ \text{and x = -4 , y = -3, we have} \\ -3\text{ = 1(-4) + c} \\ -3\text{ = -4 + c} \\ 4\text{ - 3 = c} \\ c\text{ = 1} \\ \text{Thus, the equation of the line is y = (1)x + 1} \\ y\text{ = x + 1} \end{gathered}$
