Answer:
y+6=-1/2(x-3)
Step-by-step explanation:
Point slope form: y-y1=m(x-x1)
Given that:
m=-1/2 and point (3, -6), you just add these numbers into the equation, and this gives:
y+6=-1/2(x-3)
Hope this helped!
Have a nice day!
Answer:
a) 11mph
b) 6mph
c) 25 miles
Step-by-step explanation:
She can run 12 miles in 2 hours.
She can bike 33 miles in 3 hours.
a) What is Jennifer's biking speed?
Divide:
b) What is Jennifer's running speed?
Divide:
c) Jennifer biked for 2 hours and then ran for 30 minutes. What distance did she cover?
She bikes 11 miles per hour.
2 hours would be = 11mi * 2 = 22miles
She runs 6 miles per hour.
30 minutes or 1/2 hour would be = 6mi * 1/2 = 3 miles
Add these distances.
22+3=25 miles
Answer:
200
Step-by-step explanation:
Out of those 6 numbers, 4 of them are prime sow we have the ratio of 2:3
2/3 * 300 = 200

Answer:
Perimeter of ABCD - Perimeter of PQRS = 4x + 2
Step-by-step explanation:
i. For rectangle ABCD;
length, l = 2x -3
width, w = 4x + 5
Perimeter of a rectangle = 2(l + w)
Perimeter of ABCD = 2((2x -3) + (4x + 5))
= 2(2x -3 + 4x + 5)
= 2(6x + 2)
Perimeter of ABCD = 12x + 4
ii. For rectangle PQRS;
length, l = x - 1
width, w = 3x + 2
Perimeter of a rectangle = 2(l + w)
Perimeter of PQRS = 2((x - 1) + (3x + 2))
= 2(x - 1 + 3x + 2)
= 2(4x + 1)
Perimeter of PQRS = 8x + 2
So that,
Perimeter of ABCD - Perimeter of PQRS = (12x + 4) - (8x + 2)
= 12x + 4 - 8x - 2
= 4x + 2
Perimeter of ABCD - Perimeter of PQRS = 4x + 2
