Answer:

the missing fence length = 2a² + 18

Step-by-step explanation:

3a²+15a+9 = (a²-7) + (10a-2) + 5a + ? = a² + 15a -9

? = (3a²+15a+9) - (a² + 15a -9) = 2a² + 18

Q4: Write the equation in slope-intercept form of the line that is perpendicular to
forsale [732]

Answer:

5y  = x + 11

Step-by-step explanation:

Given parameters:

  Equation of the line ;

           y  = -5x + 1

  Coordinates = (2, -1)

Find the equation of a line perpendicular;

Solution:

A line perpendicular to  y  = -5x + 1  will have slope that is a negative inverse of the given one.

Equation of a straight line is expressed as;

           y  = mx + c

y and x are the coordinates

m is the slope

c is the y-intercept

        So, the slope of the new line perpendicular is \frac{1}{5} ;

Now let us find the y-intercept of the new line;

   x = -1 and y = 2

      2  = \frac{1}{5} x (-1) + c

           c  = 2 + \frac{1}{5}   = \frac{11}{5}  

The equation of the new line is;

          y  =  \frac{1}{5}x +  \frac{11}{5}  

or multiply through by 5;

        5y  = x + 11

A sports shop has 84 employees. 25% of the employees work part-time. How many part-time employees does the sports shop have?
Zolol [24]

Answer:

The sports shop has 21 part-time employees.

Step-by-step explanation:

Solution:

What is 25% of 84?

.Y is 25% of 84

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 25% * 84

Converting percent to decimal:

p = 25%/100 = 0.25

Y = 0.25 * 84

Y = 21

Or another quicker way....

50% is half of the whole, and 25 is half of 50.

84/2/2

equals 21 too, I don't recommend to use it as row form.
