Answer:
linear y=22-5x...is linear
Answer:
3
days
Step-by-step explanation:
Let the amount of work be x.
Daniel:
10 days = x
1 day = 
x
Father:
6 days = x
1 day = 
x
Together:
1 day = x + x
= 
x + 
x
= 
x
= 
x
No. of days = 
x ÷ x
= x × 
x
= 
= 3
Answer:
x = - 4

Answer:
Area = 127.5cm²
Step-by-step explanation:
Given that,
Length of first side = 8 cm
Length of second side = 15 cm
Length of third side = 17cm
To find,
Area of triangle
to find which of the sides is hypotenuse use Pythagorus theorem
hypotenuse² = height² + base²
17² = 8² + 15²
289 = 289
hence 17 is the hypotenuse and other two are height and base
<h2>Area of triangle = 1/2 height * base</h2>
Area of triangle = 1/2 15 * 17
Area of triangle = 1/2 (255)
Area of triangle = 127.5
