Answer:
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
Answer is Ax+By=C. ... A, B, C are integers (positive or negative whole numbers)

Step-by-step explanation:
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:
The number is -1.
Step-by-step explanation:
Let the number be represented by n.
Then "9 is added to twice a number and this sum is multiplied by 6" is represented by 2n + 9, and
" the number is multiplied by 7 and 14 is added to the product" is
7n + 14.
Then the complete equation is 2n + 9 = 7n + 14.
We must solve this for n. To accomplish this, subtract 2n from both sides, obtaining 9 = 5n + 14. Then subtract 14 from both sides, obtaining
-5 = 5n. Then n must be -1.
Answer:
The ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.
Step-by-step explanation:
Let the Area of smaller watch face be
Also Let the Area of Larger watch face be
Also Let the radius of smaller watch face be
Also Let the radius of Larger watch face be
Now given:
We need to find the ratio of the radius of the smaller watch face to the radius of the larger watch face.
Solution:
Since the watch face is in circular form.
Then we can say that;
Area of the circle is equal 'π' times square of the radius 'r'.
framing in equation form we get;
So we get;
Substituting the value we get;
Now 'π' from numerator and denominator gets cancelled.
Now Taking square roots on both side we get;
Hence the ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.
