Sorry if wrong but here I go
so basically
you need to find the scale factor so
14/10=1.4 and 21/15=1.4
so I take the scale factor 1.4 and divide by 20
20/1.4= about 14.25 or to be exact 14.2857142857
Multiplying simultaneously numerator by numerator and denominator by denominator.
You can multiply fractions, multiplying simultaneously numerator by numerator and denominator by denominator.
2) Notice that whenever possible, we must simplify it to the lowest possible fraction.
Hello there! Your answer would be y = 0.5x - 3.
To find the equation, use slope intercept form, y = mx + b. <em>(m = slope, b = y intercept)</em>
For the slope, solve by subtracting the y values over the x values.
- 5 - - 3 / 0 - 4
- 2 / - 4
The negatives cancel out, and you are left with 0.5 as your slope. Plug that into m.
y = 0.5x + b
Now to find the y intercept. To do this, we can replace the x and y values into the equation and solve for b.
-5 = 0.5(4) + b
-5 = 2 + b
- 3 = b
so, the y intercept has a value of -3. Plug that in to the final equation.
y = 0.5x - 3
Hope this helps and have a great day!
D the bottom answer, A= 15.53 P= 20.42

180-135=45
