Answer:
f(x)=x+5
Step-by-step explanation:
x=-1 therefore -1+5=4
Answer:
Let's solve your system by substitution.
x+2y=6;x−y=3
Step: Solvex+2y=6for x:
x+2y=6
x+2y+−2y=6+−2y(Add -2y to both sides)
x=−2y+6
Step: Substitute−2y+6forxinx−y=3:
x−y=3
−2y+6−y=3
−3y+6=3(Simplify both sides of the equation)
−3y+6+−6=3+−6(Add -6 to both sides)
−3y=−3
−3y
−3
=
−3
−3
(Divide both sides by -3)
y=1
Step: Substitute1foryinx=−2y+6:
x=−2y+6
x=(−2)(1)+6
x=4(Simplify both sides of the equation)
Answer:
x=4 and y=1

(b) Mara's rectangle
Step-by-step explanation:
Given
Mara
Ashton
Solving (a): Draw the rectangles
First, we need to calculate the possible dimension of both rectangles.
Area is calculated as:
For Mara
Possible values of length and width are:
This is so because:
For Ashton
Possible values of length and width are:
This is so because:
<em>See attachment for diagram</em>
Solving (b): Rectangle with bigger area
Mara's rectangle has a bigger area because
<span>Amelia + Bernard + Cindy = 10w {the total of their ages is 10w}
2w + ? + ? = 10w {Amelia is 2w years old, Bernard and Cindy are the same}
? + ? = 8w {subtracted 2w from each side}
2? = 8w {added ? and ?}
? = 4w {divided each side by 2}
Cindy is 4w
</span><span>If w = 4,
4w
= 4(4){substituted 4 in for w}
= 16 {multiplied}
If w = 4, then Cindy is 16</span>
