A telescope costs $126 with a 30% discount. What was the original price?

Juli2301 [7.4K]

Answer:

$180

Step-by-step explanation:

Since the cost of the telescope with the 30% discount is $126 then $126 is 70% of the original price. Remember 100-30=70. To find the original price set up a proportion with these values:

$\frac{126}{x}=\frac{70}{100}$

Solve for the original price by cross multiplying numerator with denominator.

x(70) = 126(100)

70x = 12600

x= $180

What is an equation of the line perpendicular to y=-x-2 and through (-2, 4)?

Salsk061 [2.6K]

Answer: y = x + 6

Step-by-step explanation:

$\mathrm{Find\:the\:line\:}\mathbf{y=mx+b}\mathrm{\:perpendicular\:to\:}y=-x-2\mathrm{\:that\:passes\:through\:}\left(-2,\:4\right)$

$\mathrm{For\:a\:line\:equation\:for\:the\:form\:of\:}\mathbf{y=mx+b}\mathrm{,\:the\:slope\:is\:}\mathbf{m}$

$m=-1$

$\mathrm{The\:perpendicular\:slope\:is\:the\:negative\:reciprocal\:of\:the\:given\:slope}$

$\left(-1\right)m_p=-1$

$\frac{\left(-1\right)m_p}{-1}=\frac{-1}{-1}$

$m_p=1$

$\mathrm{Compute\:the\:line\:equation\:}\mathbf{y=mx+b}\mathrm{\:for\:slope\:m=}1\mathrm{\:and\:passing\:through\:}\left(-2,\:4\right)$ $\mathrm{Plug\:the\:slope\:}1\mathrm{\:into\:}y=mx+b$
