What is the y-intercept of the equation of the line that is perpendicular to the line y=3/5x+10 and passes through the point (15,-5)? A. y=3/5x-20 B. y=-3/5x+20 C. y=5/3x-20 D. y=-5/3x+20

10 is the y intercept

Step-by-step explanation:

follow y=mx+b b is equal to the y intercept

D. y=-5/3x+20

Step-by-step explanation:

We have the information y=3/5x+10, the lines are perpendicular, and the new line passes through (15,-5). The slops of perpendicular lines are negative reciprocals so you need to find the negative reciprocal of 3/5, so flip it to 5/3 and multiply by -1, we get the slope of the new line as -5/3. So far we have the equation y=-5/3x+b. We are given a point on the line, (15,-5), we can plug these into the equation as x and y to solve for the y-intercept, b. You set it up as -5=-5/3(15)+b. First you multiply to get -5=-25+b, then you add 25 to both sides to isolate the variable and you get b=20. Then you can use b to complete your equation with y=-5/3x+20, or letter D.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
