Answer:
x = - 2
Step-by-step explanation:
y = 4 is the equation of a horizontal line parallel to the x- axis.
Thus a perpendicular line will be vertical and parallel to the y- axis.
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 2, 1) with x- coordinate - 2, thus
x = - 2 ← equation of perpendicular line
Answer:
39
Step-by-step explanation:
1. Use the Pythagorean theorom: a^2+b^2=c^2.
C is the missing side here, which is the hypotenuse of the triangle. The other two sides and be put into the equation either way. Doesn't matter the order.
15^2 + 36^2 =c^2
2. Evaluate 15^2 and 36^2 and add the results.
15^2 = 225
36^2 = 1,296
225+1,296= 1,521
3. Take the square root of the answer.
√1521 = 39
The answer should be (3x and 5 in a fraction) 2-3x over 5
Answer

Answer:
124 boys and 161 girls
Step-by-step explanation:
There are 285 students total. Divide 285 by 2, you get 142.5. Since you can't have half a student, lets round it up to 143. Now, there are 19 more girls than guys, so you would subtract 19 from 143. When you do that, (143-19) you get 124. Then you take 285 and subtract 124. You get 161.
Hope this is correct!
