Write an equation of the line perpendicular to the given line that contains P.
Yakvenalex [24]

Answer:

  y +5 = -1/3(x -3)

Step-by-step explanation:

The slope of the given line is 3. The slope of the perpendicular line is the negative reciprocal of that, -1/3. Then the point-slope equation is ...

  y -y1 = m(x -x1) . . . . line with slope m through point (x1, y1)

  y -(-5) = -1/3(x -3)

  y +5 = -1/3(x -3)

Bill is 15 years older than Paul. Paul is 7 years older than half Milo's age. The sum of all three ages is 85. How old is Bill?
katrin2010 [14]

Answer:

Step-by-step explanation:

Let Milo's age = x

Paul's \ age =\dfrac{1}{2}x+7\\\\\\Bill's \ age = \dfrac{1}{2}x + 7  +15 =\dfrac{1}{2}x+22

Sum of all three ages = 85

x +\dfrac{1}{2}x+7 +\dfrac{1}{2}x+22 = 85\\x +\dfrac{1}{2}x+\dfrac{1}{2}x+7+22 =85\\2x+29=85\\     2x  = 85-29\\\\     2x  = 56\\\\      x = \dfrac{56}{2}\\\\x =28 \ years\\\\\\Bill's \  age =\dfrac{1}{2}x+22 =\dfrac{1}{2}*28+22\\\\\\= 14+22\\

Bill's age = 36 years

Check if (1,6) is the solution to the system shown below
Andre45 [30]

Answer:

no

Step-by-step explanation:

To determine if (1, 6) is a solution, substitute x = 1, y = 6 into the left side of both equations and if the value obtained equals the right side then it is a solution.

10(1) - 6 = 10 - 6 = 4 ≠ - 6

- 10(1) + 5(6) = - 10 + 30 = 20 ≠ 30

Then (1, 6 ) is not a solution to the system

Lady bird [3.3K]

Answer:JKL and ∠RST are complementary.

m∠JKL = 36° and m∠RST = ( x + 15)°.

Find the value of x and the measure of ∠RST .

complementary angles are two angles whose sum is 90°

36%2Bx+%2B+15=90°

51%2Bx+=90°

x+=90-51°

x+=39°

->the measure of ∠RST== ( 39 + 15)=54°

both answer and explanation
