A quadratic equation is a polynomial equation in which a single variable appears in a 2nd-degree term, and all other terms are 1st degree or less. A quadratic inequality is a quadratic equation in which the equal sign has been replaced by an inequality symbol.

The relation of selection A would not be a quadratic equation if the relation symbol were an equal sign, hence it is not a quadratic inequality. The best choice is

... A. y ≤ y² + x²

Answer:

7 strips

Step-by-step explanation:

One way we can solve this is through guess and check. Let's start with 4 strips. If Joe's grandma makes 4 strips, she will have 0.75*4 = 3.00 yards of fabric. That's a really low amount of fabric. Let's double that to 8, where Joe's grandma would need 0.75*8 = 6.00 yards of fabric. That's really close! Let's remove one strip. 0.75*7 = 5.25 yards of fabric. Perfect! Joe's grandma can cut exactly 7 strips

There are two jobs you can apply for. the first job pays $22,000 the first year, with raises of $4,000 each year thereafter. the

jasenka [17]

We let the number of years that the two jobs will have the same payment be denoted as t. Equating the wages of these two jobs after t - 1 years will give us an equation of,
22,000 + 4000(t -1) = 26,000 + 2000(t - 1)
The value of t from the generated equation is 3. Therefore, after 3 years the jobs will be paying the same wages.

Solve for c 6/15=2/c

saul85 [17]

$\frac{6}{15}$ = $\frac{2}{c}$ Multiply both sides by 15
6 = $\frac{30}{c}$ Multiply both sides by c
6c = 30 Divide both sides by 6
c = 5

adelina 88 [10]

QUESTION :-

what is the value of x to the nearest whole number?

ANSWER :-

$\cos( \theta) = \frac{base}{hypotenuse} \\ \cos(30) = \frac{x}{24} \\ \frac{ \sqrt{3} }{ \cancel2} = \frac{x}{ \cancel{24}} = \frac{x}{12} \\ 1.732 = \frac{x}{12} \\ 12 \times 1.732 = x \\ x = 20.7$

the nearest whole number-->

20.7 --> approximately --> 21 units
