How many solutions does the system of equations have?
SIZIF [17.4K]
The answer is d) none because substituting -1/4x + 5/3 for y in the first equation gives 3x - 3x + 5/3 = 20 so 5/3 = 20 which is not true.

Sav [38]

Answer:

Height should be ≤ 9 inches.

Step-by-step explanation:

Given:

Frank is making a pennant in the shape of a triangle for his senior class photo.

Base of triangle = 6 in

Area of triangle ≤ 27 in^2

Let height of the triangle be h

Now we now that,

Area of triangle = \frac{1}{2}\times base \times height

\frac{1}{2}\times 6 \times h \leq 27\\\\3h\leq 27\\\\h\leq \frac{27}{3}\\\\h\leq 9 \ in.

Hence the height of the triangle must be at most or ≤ 9 inches.

Answer:

Step-by-step example explanation:

DOMAIN:

{

x

∣

x

≠

3

2

}

RANGE:

{

y

∣

y

≠

3

2

}

Explanation:

The domain consists of all numbers you can legally plug into the original. The excluded "illegal" values would be dividing by zero or negatives under square roots.

This expression has a denominator, so there is a risk of illegally dividing by zero. This would happen only if

2

x

−

3

=

0

2

x

=

3

x

=

3

2

This means that

x

=

3

/

2

is excluded from the domain. Therefore,

Domain: All real numbers except

x

=

3

/

2

. More formally, you could state the domain as

{

x

∣

x

≠

3

2

}

.

For rational functions, you find the range by evaluating the degree of the numerator compared to the degree of the denominator. If the degree of the top > degree of bottoms, then you have a horizontal asymptote at

y

=

0

. If they are equal, you have a horizontal asymptote. The coefficient of highest degree in the numerator is divided by the coefficient of the highest degree on the bottom. The result is

y

=

that fraction. So in our case, you have a horizontal asymptote at

y

=

3
