Answer:
3 and 8 is a pair of corresponding.
Let :
T = Theresa age
H = her brother
We know :
T = H - 14
T + H = 35
Substitute T
H -14 + H = 35
2H - 14 = 35
2H = 49
H = 49/2 = 24.5
Since we know H = 24.5 we then can substitute it to either equation.
T = H - 14
T = 24.5 - 14
T = 10.5
Theresa is 10.5 years old
Her brother is 24.5 years old
Answer:
26
Step-by-step explanation:
Problem: f(x) = 28 + x + 7
Plug in f(-9)
New equation: f(-9) = 28 + (-9) + 7
Simplify: f(-9) = 26
<u>Answer: f(-9) = 26</u>
Answer:
the graph is a linear
Step-by-step explanation:
14x +5y =1000
let X=0
14(0)+5y=1000
5y=1000
y=200
y(0;200)
let y =0
14y+5y=1000
14x+5(0)=1000
14x=1000
X=71.43
X(71.43;0)
