The system of equations has infinitely many solutions
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
-3x + 3y = 12 ------- eqn 1
y = x + 4 --------- eqn 2
We have to find the solution to the system of equations
We can use substitution method
Substitute eqn 2 in eqn 1
-3x + 3(x + 4) = 12
-3x + 3x + 12 = 12
-3x + 12 = -3x + 12
If we have terms with same terms on both sides of equal sign, then we have infinitely many solutions
Thus the system of equations has infinitely many solutions
Answer:27/2
Step-by-step explanation: The ratio stays the same. So 4/6 = 9/x. Solve that and get 27/2
Firstly, you know you have 27 (35/100)
Make this an improper fraction. 2735/100
Simplify this as much as you can. 547/20
Find how many times 20 will go into 540, and use the 7/20 as the fraction part of your mixed number.
Now, make as many whole as you can and states your remaining. 27 7/20
Answer:
degree 3, binomial
Step-by-step explanation:
the highest exponent is the degree, it's two terms so bi meaning 2 makes it a binomial
Step-by-step explanation:
diameter = 3ft
radius = 3/2 ft
perimeter of semicircle= πr = π (3/2) = 3.14×3/2
= 4.71 ft
