Answer:

False.

Step-by-step explanation:

xy is one term.

Each term in an algebraic expression is separated by a + or - sign.

For example, x^2 - xy + y^2  has 3 terms

The equation is 36 - 4x = 6.

Solution:

To write the equation without fraction.

[tex]$4-\frac{4}{9} x=\frac{2}{3}[/tex]

[tex]$\frac{4}{1} -\frac{4}{9} x=\frac{2}{3}[/tex]

The denominators must be same to add/subtract the fractions.

LCM of 1, 9 and 3 = 9.

Multiply first term by [tex]\frac{9}{9}[/tex] and [tex]\frac{2}{3}[/tex] by [tex]\frac{3}{3}[/tex] to make the denominator same.

[tex]$\frac{4\times9}{1\times9} -\frac{4}{9} x=\frac{2\times3}{3\times3}[/tex]

[tex]$\frac{36}{9} -\frac{4}{9} x=\frac{6}{9}[/tex]

[tex]$\frac{36-4x}{9} =\frac{6}{9}[/tex]

Multiply by 9 on both sides.

[tex]$\frac{36-4x}{9}\times9 =\frac{6}{9}\times9[/tex]

Both 9 in the numerator and denominator get canceled.

36 - 4x = 6

This term does not have fraction.

Hence the equation is 36 - 4x = 6.

Answer:

  4096

Step-by-step explanation:

You want to evaluate (-8)⁴.

The exponent of 4 signifies the base (-8) is a factor 4 times in the product:

  (-8)⁴ = (-8)×(-8)×(-8)×(-8)

The multiplication is accomplished in the usual way. There are an even number of minus signs, so the product will be positive. The value is ...

  (-8)×(-8)×(-8)×(-8) = 8·8·8·8 = 64·8·8 = 512·8 = 4096

  (-8)⁴ = 4096

__

Additional comment

It can be faster to decompose the exponent into powers of 2. This makes it possible to use squaring to reduce the number of operations required.

  (-8)⁴ = (8²)² = 64·64 = 4096

Answer:

24:6

Step-by-step explanation:

It is 4 to 1. The ratios added up is 5. So 30 divided by 5 is 6. So 1 (the ratio) is 6 games. 4x6=24. So the new ratio is 24 to 6. 24 wins and 6 losses.

The team won 24 games and lost 6, calculated by first solving for x in the equation 5x = 30 and then applying the 4:1 win-to-loss ratio.

If the ratio of wins to losses for Loyola basketball is 4 to 1, and they played 30 games, we want to find how many of those games were wins and how many were losses. Let's say the number of wins is 4x and the number of losses is x. According to the ratio, there are 4 wins for every loss, which makes the total number of games 4x + x = 5x.

Since we know 5x is 30 games, we can solve for x to find out the number of losses. Dividing 30 by 5, we get x = 6. That's the number of losses. To find the number of wins, we multiply 4 times the number of losses (4x), which gives us 4 * 6 = 24 wins.

The dimensions of the rectangle are: Width = 3 feet, Length = 7 feet.

The formula for Area of rectangle

Area = length x width

Given:

Area of rectangle = 21 square feet.

Let the width of the rectangle is w feet.

According to the given information, the length of the rectangle is four feet longer than the width,

So, length = w + 4 feet.

So, Area of rectangle = length x width

21 = w (w+4)

[tex]\[21 = w^2 + 4w\][/tex]

[tex]\[w^2 + 4w - 21 = 0\][/tex]

Solve this quadratic equation, set it equal to zero:

w² + 7w -3w -21 =0

w(w+7)-3 (w+7)= 0

(w+7)(w-3) =0

Setting each factor equal to zero:

w+ 7 =0

w= -7

or, w - 3 =0

w = 3

So, the length of rectangle is

= 3+ 4

= 7 feet

We can rewrite it as:

[tex]y = \frac{ \sin(x) }{ \cos(x) } [/tex]

This graph has vertical asymptotes at where the denominator is zero.

[tex] \cos(x) = 0 \\ \implies \: x = \frac{\pi}{2} \: or \: \frac{3\pi}{2} [/tex]

The correct options are : (b) [tex]\( x = \frac{\pi}{2} \)[/tex] and (d) [tex]\( x = \frac{3\pi}{2} \)[/tex]

The asymptotes of the tangent graph are the vertical lines where the tangent function is undefined. The tangent function, [tex]\(\tan(x)\)[/tex], is undefined where the cosine function is zero, which happens at:

[tex]\[ x = \frac{\pi}{2} + k\pi \quad \text{for integer values of } k \][/tex]

So, let's check each given value to see if it fits this form.

1. [tex]\( x = \frac{\pi}{4} \)[/tex]

[tex]\[ \frac{\pi}{4} \neq \frac{\pi}{2} + k\pi \][/tex]

This is not an asymptote.

2. [tex]\( x = \frac{\pi}{2} \)[/tex]

[tex]\[ \frac{\pi}{2} = \frac{\pi}{2} + 0 \times \pi \][/tex]

This is an asymptote.

3.[tex]\( x = \pi \)[/tex]

A second linear equation that forms a system with exactly one solution with 3x+9y=-8 could be y = -2x + 4, as it has a different slope and y-intercept, ensuring the lines intersect at one point.

To create a system of equations with exactly one solution, you need to write a second linear equation that has a different slope than the first equation (3x+9y=-8) but does not share any points with it. The slope-intercept form y = mx + b, where m is the slope and b is the y-intercept, will be used to construct our new equation.

Given the slope-intercept form y = 9 + 3x as an example, we see that the slope (m) is 3 and the y-intercept (b) is 9. To ensure our second equation has only one solution when paired with the first equation, we can select a different slope and y-intercept. For instance, an equation such as y = -2x + 4 would suffice, as it has a different slope (-2) and intercept (4), ensuring that the two lines will cross at exactly one point on the graph.

In summary, the original equation 3x+9y=-8 and the second equation y = -2x + 4 when graphed will intersect at exactly one point, forming a system of linear equations with one solution. This process involves selecting different values for the slope and y-intercept to make sure the lines are not parallel and do not coincide.

Answer:

431

Step-by-step explanation:

Let

[tex]p(x) = {x}^{6} - 4 {x}^{4} + 4 {x}^{2} - 10[/tex]

We want to find the remainder when this polynomial is divided by x+3.

We use the remainder theorem.

Which says that, when p(x) is divided by x-a, the remainder is p(a)=R.

Therefore the remainder when p(x) is divided by x+3 is p(-3).

[tex]p( - 3) = {( - 3)}^{6} - 4 { (- 3)}^{4} + 4 {( - 3)}^{2} - 10[/tex]

We evaluate:

[tex]p( - 3) = 729 - 4 (81)+ 4 {( 9)} - 10[/tex]

We multiply to get;

[tex]p( - 3) = 729 - 324+ 36- 10[/tex]

We simplify to get:

[tex]p( - 3) =431[/tex]

Therefore the remainder is 431
