Answer:
120%
Step-by-step explanation:
Given that,
The diameter of the raw cookie is 2 1/2 inches i.e. 5/2 inches
After baking the cookie, the diameter is 5 1/2 inches i.e. 11/2inches
We need to find by what factor does the cookie expand.
So, the cookie will expand 120%.
Answer:
see the attached graph
Step-by-step explanation:
When an equation is in <em>standard form</em> (or almost standard form), I like to put it into <em>intercept form</em> for graphing. Here, it is convenient to divide the equation by 2 to put it in standard form (coefficients mutually prime).
x +3y = -3
Now, it is convenient to divide by the constant on the right (-3) to put the equation into intercept form:
x/(-3) +y/(-1) = 1
The denominators are the x- and y-intercepts, respectively. Plot those, (-3, 0) and (0, -1), and draw the line through them.
