Answer:
Step-by-step explanation:
(3,2),(6,3)
slope = (y2 - y1) /(x2 - x1)
slope = (3 - 2) / (6 - 3) = 1/3
y = mx + b
slope(m) = 1/3
use either of ur points...(3,2)...x = 3 and y= 2
now sub and find b, the y int
2 = 1/3(3) + b
2 = 1 + b
2 - 1 = b
1 = b
so ur equation is : y = 1/3x + 1

Answer:
(C)85.56 cm², 12.4 cm
Step-by-step explanation:
The Area of the screen of the new phone is :
19.68cm² + Area of the current phone screen size
The current phone screen size has dimensions: 6.1 cm and 10.8 cm,
Area of the current phone screen size = 6.1 cm × 10.8cm
Area of the current phone screen size = 65.88 cm²
Hence, The Area of the screen of the new phone is :
19.68cm² + Area of the current phone screen size
= 19.68cm² + 65.88cm²
= 85.56 cm²
The new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and ___
The is calculated as:
85.56cm²/6.9cm
= 12.4cm
Therefore, the new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and 12.4cm
Option C is correct
Answer: She has 17 ostriches.
Step-by-step explanation:
We know , ostrich has 2 legs where as llama has 4 legs.
Let x be the number of ostriches and y be the number of llamas.
Then, as per given , we have the following linear equations :

Multiply 2 to eqn (ii) , we get

Subtract (iii) from (i) , we get

Put this in (ii) , we get 
Hence, there are 17 ostriches and 16 llamas.
Answer:
75 km
Step-by-step explanation:
Given the following :
Scale on first map = 1cm to 20 km
Distance fromFresno to San Francisco = 15km on first map
Scale on 2nd map = 1cm to 100 km
1cm / 20km = 15km
Let of Distance from Fresno to San Francisco on 2nd map = d
1cm / 100km = d
1 : 20 = 15
1 : 100 = d
20/ 100 = 15/d
1/5 = 15/d
d = 15 * 5
d = 75 km
