how many solutions does the system of equations have? 6x+18y=9 and y=-1/3x+1/2
Answers
Answer:
D) Infinitely many
Step-by-step explanation:
Given system of equations
[tex]\left \{ {{6x+18y=9} \atop {y=-\frac{1}{3}x+\frac{1}{2} }} \right.[/tex]
Substitute second equation into first equation
[tex]6x+18y=9\\\\6x+18(-\frac{1}{3}x+\frac{1}{2})=9\\ \\6x-6x+9=9\\\\9=9[/tex]
Therefore, since both sides are equal to each other no matter what, there are infinitely many solutions.
You can confirm that there are infinitely many solutions by looking at the graph of both functions. They overlap each other, so every solution will work.
Answer:
Infinitely many solutionsStep-by-step explanation:
Given:
6x + 18y = 9y = -1/3x + 1/2Solution:
18y = -6x + 9y = -1/3x + 1/2
=> 18y = -6x + 918(y = -1/3x + 1/2)
=> 18y = -6x + 918y = -6x + 9
Since both the equations are the same, this system of equations has infinitely many solutions.

joe has a handful of dimes and quarters that values to $5.30. He has one fewer than twice as many dimes than quarters. How many of each coin does he have?
Answers
Answer:
12 quarters 23 dimes
Step-by-step explanation:
x(0.25)+(2x-1)(0.10)=5.30
0.25x+0.2x-0.10=5.30
0.45x=5.40
x=12
12 quarters
12(2)=24-1=23 dimes
Joe has 12 quarters coins and 23 dimes coins .
What is equation ?Equation is a combination of mathematical variables, in which two mathematical expressions are equal.
Let the number of quarters be n,
Therefore the number of dimes will be 2n-1.
Given that,
The total value of dimes and quarters is $5.30.
Write above text in equation form.
(0.25)n+(0.10)(2n-1)=5.30
0.25n+0.20n-0.10=5.30
.45n=5.40
n=12
And 2n-1=23
Means Joe has 12 quarters coin and 23 dimes coins .

Suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When carrying 10 gallons of fuel, the airplane weighs 2064 pounds. When carrying 45 gallons of fuel, it weighs 2288 pounds. How much does the airplane weigh if it is carrying 60 gallons of fuel?
Answers
Answer:
Now, to answer the question, we need to add the weight of (58-42) = 16 gallons of fuel to the weight of the plane
carrying 42 gallons of fuel, 2331 pounds.
So, the answer is 2331 + 16*5.5 = 2419 pounds.

Give each trig ratio as a fraction in simplest form. First find the measure of the missing side using Pythagorean Theorem a2 + b2 = c2
Answers
Answer:
see step-by-step for full solution
Step-by-step explanation:
First use Pythagoras' Theorem to calculate the length of the missing leg PQ, where a and b are the legs and c is the hypotenuse of a right angled triangle.
a² + b² = c²
⇒ 14² + PQ² = 50²
⇒ 196 + PQ² = 2500
⇒ PQ² = 2500 - 196
⇒ PQ² = 2304
⇒ PQ = √2304 = 48
Therefore, the measure of the missing side PQ is 48.
Now use the 3 basic trigonometry ratios, where O = leg opposite to the angle, A = leg adjacent to the angle, and H = hypotenuse:
[tex]sin(\theta)=\frac{O}{H} \\\\cos(\theta)=\frac{A}{H} \\\\tan(\theta)=\frac{O}{A} \\[/tex]
If angle = Q, then O = 14, A = 48, H =50. Therefore,
sin(Q) = O/H = 14/50 = 7/25
cos(Q) = A/H = 48/50 = 24/25
tan(Q) = O/A = 14/48 = 7/24
If angle = R, then O = 48, A = 14, H = 50. Therefore,
sin(R) = O/H = 48/50 = 24/25
cos(R) = A/H = 14/50 = 7/25
tan(R) = O/A = 48/14 = 24/7
