Write the equation of the line that passes through (-4, 3) and is perpendicular to the line y = 7/5x -3/5
tensa zangetsu [6.8K]

Answer:

y = -\frac{5}{7}x + \frac{1}{7}

Step-by-step explanation:

3 = −5⁄7[−4] + b

2 6⁄7

\frac{1}{7} = b \\ \\ y = -\frac{5}{7}x + \frac{1}{7}

Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE <em>RATE</em><em> </em><em>OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>], so 1 2⁄5 [or 7⁄5] becomes −5⁄7.

I am joyous to assist you anytime.

Airida [17]

Social Studies rate, S = 30/ 1.5 = 20pages/hr

Novel rate, N = 150/2 = 75pages/hr

Novel rate as a % of Social Studies rate...

N/S × 100% = 75/20 × 100% = 375%

What is the estimate of the sum of 165, 123, 376 and 134 using front end estimation?
RUDIKE [14]
165 rounded to the nearest front (the hundreds place for all of them in this case) is 200. 123 rounded to the nearest hundred is 100, 376 rounded to the nearest hundred is 400, and 134 rounded to the nearest hundred is 100. Adding 200 + 100 + 400 + 100, we get 800.
