ANSWER

[tex]B(2,-3)[/tex]

[tex]C(-2,3)[/tex]

EXPLANATION

The given point has coordinates A(-2,-3).

The rule for the reflection across the y-axis is

[tex](x,y)\to(-x,y)[/tex]

We apply this rule to obtain the coordinates of B.

[tex]A(-2,-3)\to B(--2,-3)[/tex]

Simplify the coordinates of B to get:

[tex]A(-2,-3)\to B(2,-3)[/tex]

The rule for reflection across the x-axis is

[tex](x,y)\to (x,-y)[/tex]

When the point A(-2,-3) is reflected across the x-axis to obtain C, then the coordinates of C are:

[tex]A(-2,-3)\to C(-2,--3)[/tex]

[tex]A(-2,-3)\to C(-2,3)[/tex]

Answer:

y = - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

y - 3 = - 2(x + 5) ← distribute right side

y - 3 = - 2x - 10 ( add 3 to both sides )

y = - 2x - 7 ← in slope- intercept form

with y- intercept c = - 7

y = - 7 is the y-intercept of the line.

A line's equation has the conventional form ax + by + c = 0. Here, the variables are x and y, the coefficients are a and b, and the constant term is c. It is a first-order equation with the variables x and y. The coordinates of the point on the line shown in the coordinate plane are represented by the values of x and y.

Given

The equation of a line in slope- intercept form is

Answer:

(y + 2)²(y + 4)

Step-by-step explanation:

Factor the denominators of both fractions

y² + 4y + 4 = (y + 2)²

y² + 6y + 8 = (y + 2)(y + 4)

The least common denominator is (y + 2)²(y + 4)

Answer:

Step-by-step explanation:

y²+4y+4=(y+2)² =(y+2)(y+2)

Step-by-step explanation:

12 can be multipled by 4 and 4 and 8 can be multipled by 4 and 2 so 4 is the greatest common factor

Answer:

4

Step-by-step explanation:

For this case we have the following expression:

[tex]ax ^ 4[/tex]

We must find the value of the expression when:

[tex]a = 2\\x = 1[/tex]

Substituting the values in the expression we have:

[tex]2 (1) ^ 4 = 2 * 1 = 2[/tex]

Thus, the value of the expression is 2.

Answer:

The value of the expression is 2

Option A

Answer:

The correct answer is A

Step-by-step explanation:

The given expression is [tex]ax^4[/tex].

We want to evaluate this expression for: [tex]a=2,x=1[/tex].

We just have to substitute a=2 wherever we see 'a' in the expression [tex]ax^4[/tex] and x=1 wherever see x in the same expression.

We perform the substitution to get:

[tex]2(1)^4[/tex]

We evaluate the exponent to get:

 [tex]2(1)[/tex]

We now multiply to get:

 [tex]2[/tex]

Answer:

4

Step-by-step explanation:

Recall that the equation for a straight line is y = mx + b, where m is the slope and b is the y-intercept.

we can see that the slope is negative (i.e graph goes from top left to bottom right).  hence the value for m must be negative.

By looking at the answer choices, only 2 and 4 have negative x-terms, hence we can ignore 1 and 3.

Also we notice that the graph intersects the y-axis at y = 2, hence the y-intercept must be 2.

Only Answer 4 satisfies both requirements and is the correct answer.

Hello There!

To find the quotient of [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{1}{8}[/tex],

we need to multiply by the reciprocal meaning that the fraction

[tex]\frac{3}{4}[/tex] stays the same but we flip the numerator and

denominator for our second fraction so it will end up being

[tex]\frac{8}{1}[/tex] which is the same thing as 8 so the second choice

is your answer.

Answer: [tex]x=\frac{1}{3}[/tex]

Step-by-step explanation:

You need to remember the Negative exponent rule:

[tex]a^{-n}=\frac{1}{a^n}[/tex]

Then, having the equation [tex]9x^{-1} - 2 = 25[/tex], you can rewrite it in this form:

[tex]\frac{9}{x} - 2 = 25[/tex]

Now add 2 to both sides of the equation:

[tex]\frac{9}{x} - 2+2 = 25+2\\\\\frac{9}{x}=27[/tex]

Multiply both sides of the equation by "x":

[tex](x)(\frac{9}{x})=27(x)\\\\9=27x[/tex]

 And finally divide both sides of the equation by 27.

The value of "x" is:

[tex]x=\frac{9}{27}\\\\x=\frac{1}{3}[/tex]

Answer:

36

Step-by-step explanation:

You take 1/2 the linear term's coefficient and square it.

The linear term is the term that contains just an x and a number -- in this case 12x

Take 1/2 12 = 6

and square it

6^2 = 36

So when you've done that you should get

x^2 + 12x + 36 = 11 + 36

x^2 + 12x + 36 = 47

since 5 is the y coordinate, subtract 8. 5-8=-3!

Step-by-step explanation:

[tex]6 \frac{3}{4}[/tex] hours

First, find the time it takes to paint each section with this formula: [tex]\frac{\frac{1}{2}}{\frac{2}{3}}[/tex]

You can use keep, change, flip, to make this multiplication. [tex]\frac{1}{2} * \frac{3}{2}[/tex]

Multiply the numerators. [tex]1 * 3 = 3[/tex]

Multiply the denominators. [tex]2 * 2 = 4[/tex]

So, it takes [tex]\frac{3}{4}[/tex] hour to paint one section of fence.

Now, we just need to find how long it takes to paint 9 sections. [tex]9 * \frac{3}{4}[/tex]

Multiply. [tex]\frac{27}{4}[/tex]

Finally, simplify. [tex]6 \frac{3}{4}[/tex]

For this case we have that by definition, an equation of the second degree is given by:

[tex]ax ^ 2 + bx + c = 0[/tex]

We have the following equation:

[tex]0.3x ^ 2 + 5x-7 = 0[/tex]

Then, according to the definition above, we have to:

[tex]a = 0.3\\b = 5\\c = -7[/tex]

Thus, b equals 5.

Answer:

[tex]b = 5[/tex]

Option C

For this case we must simplify the given expression:

Rewriting we have:

[tex]\sqrt [3] {\frac {2 * 5x ^ 5} {2 * 27x ^ 8}} =\\\sqrt [3] {\frac {5x ^ 5} {27x ^ 8}} =[/tex]

By definition of division of powers of equal base, the same base is placed and the exponents are subtracted:

[tex]\sqrt [3] {\frac {5x ^ {5-8}} {27}} =\\\sqrt [3] {\frac {5x ^ {- 3}} {27}} =\\\sqrt [3] {\frac {5} {27x ^ 3}} =[/tex]

We have to:

[tex]\sqrt [3] {27x ^ 3} = 3x[/tex]

Then, the expression is reduced to:

[tex]\frac {\sqrt [3] {5}} {3x}[/tex]

Answer:

y + 0.5 = 3(x - 2).

Step-by-step explanation:

We use the point-slope form of the equation which is y - y1 = m(x - x1).

Here m = 3 , x1 = 2 and y1 = -0.5, so the equation is:

y - (-0.5) = 3(x - 2)

y + 0.5 = 3(x - 2).

Step-by-step explanation:

The longest diagonal in the box is the line between one of the top corners to the opposite bottom corner.

Calculate the length of the longest diagonal in the box:

The diagonal of the base =  √(6^2 + 8^2)

= √100 = 10 inches.

The longest diagonal = √( 24^2 + 10^2)

= √676

=  26 inches

=  26 * 2.54

=  66.04 cms.

Therefore the cylinder (length 63.5 cms) rod can fit in the box.

Step-by-step explanation:

Error is the difference from the nominal value, hence the nominal value is what is subtracted from x. We want the magnitude of that difference, | x-11.93 |, to be less than the maximum error value, 0.02, so the inequality is ...

  |x -11.93| ≤ 0.02

__

We can solve this by "unfolding" it, then adding 11.93:

  -0.02 ≤ x -11.93 ≤ 0.02

where

a is the initial value

b is the base

we know that
