P=a+b+c. Sub in what we know: 29=a+a+(a+5). Combine like terms: 29=3a+5. Subtract 5 from both sides: 24=3a. Divide by 3: 8=a. Short sides: A=8m, b=8m, long side: c=13m. :)
Answer:
I am not sure which one it is due to what you put in. I think it would be A.
x = 0
y = 2/3
Step-by-step explanation:
Step: Solve x + 6y= 4 for x:
x + 6y + −6y = 4 + −6y
x= −6y + 4
Step: Substitute −6y + 4 for x in 2x + 3y = 2:
2x + 3y = 2
2 (−6y + 4) + 3y = 2
−9y + 8 = 2
−9y + 8 + −8 = 2 + −8
−9y = −6
-9y/-9 = -6/-9
y = 2/3
Step: Substitute 2/3 for y in x = −6y + 4:
x = −6y + 4
x = -6 (2/3) + 4
x = 0
Sorry if it is long and confusing. But I hope this helps!
Answer:
The possible values are a = -2.5 or a = 4.5.
Step-by-step explanation:
Composite function:
The composite function of f(x) and g(x) is given by:
In this case:
So
Value of a so that the y-intercept of the graph of the composite function (fog)(x) is (0, 25).
This means that when 
. So
Solving a quadratic equation, by Bhaskara:
The possible values are a = -2.5 or a = 4.5.
The sign of the x-coordinate changes; the y-coordinate stays the same.
