Answer:
b2+11b-42 = (b+14)(b-3) when factored
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
So r+c=42
c=4+r
subsitute c=4+r for r in r+c=42
r+4+r=42
add like terms
2r+4=42
subtract 4 from both sides
2r=38
divide both sides by 2
r=19
rob=19
subsitute r=19 for r in c=4+r
c=19+4
carly=23
They have to be straight line objects with no curves
The point-slope form:
The slope-intercept form:
The formula of a slope:
We have the points (1, -5) and (-3, -7). Substitute:
Rewrite to the slope-intercept form:
<em>use distributive property</em>
<em>subtract 7 from both sides</em>
