Answer:
The total cost of 1 belt and 1 tie is $13 and $39 respectively.
Step-by-step explanation:
Given that,
The cost of 4 belts and 5 ties is $247.
Each tie costs 3 times as much as a belt.
Let the cost of a belt is x and that of a tie is y.
ATQ,
4x + 5y = 247 ...(1)
y = 3x ....(2)
Put the value of y from equation (2) in equation (1)
4x + 5(3x) = 247
4x + 15x = 247
19x = 247
x = 13
Put the value in equation (2)
y = 3x
= 3(13)
= 39
So, the total cost of 1 belt and 1 tie is $13 and $39 respectively.
T(x) is the only function up above where the highest degree is a 2, which is what a quadratic function is: a function of degree 2
Well it’s a 90 degree angle so it’s a right angle
Hello!
First of all, let's add 50 to both sides.
x/-3=50
Now we multiply both sides by -3.
x= -150
I hope this helps!
