a wire that is 8 2/3 yards long can be cut into how many 2 foot long pieces

Answer:

parallel = 4/3

perpendicular =-3/4

Step-by-step explanation:

Solve for y

-4x+3y=11

Add 4x to each side

3y = 4x+11

Divide by 3

y = 4/3 x +11/3

This is in the form y = mx+b where m is the slope

m =4/3

The parallel line has the same slope

parallel slope is 4/3

The perpendicular line has a negative reciprocal slope

m = -(1 /4/3) = - 3/4

Answer:

[tex]\frac{4}{3}[/tex] and - [tex]\frac{3}{4}[/tex]

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

- 4x + 3y = 11 ( add 4x to both sides )

3y = 4x + 11 ( divide all terms by 3 )

y = [tex]\frac{4}{3}[/tex] x + [tex]\frac{11}{3}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{4}{3}[/tex]

Parallel lines have equal slopes, thus

slope of parallel line = [tex]\frac{4}{3}[/tex]

Give a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{4}{3} }[/tex] = - [tex]\frac{3}{4}[/tex]

Answer:

Step-by-step explanation:

1) determine what we know. We know that...

a) 156 total messages were sent

b) Jim sent 6 less that carmen

c) reuben sent 4 times as many as jim

2) create an equation with the information we know

(J= amount of messages jim sent, R= amount of messages reuben sent and C= amount of messages carmen sent)

(jim)         (reuben)     (carmen)    (total)

C - 6     +    J(4)    +    C            = 156

Now, isolate "C" on one side of the "="

3) add 6 to both sides of the equation:

C - 6 + J(4) + C =156

   -6                  -6

C + J(4) + C = 150

4) Combine like terms. In this case, combine the two Cs into Cx2:

C(2) +J(4) = 150

5) subtract "J(4)" from both sides of the "="

C(2) + J(4) = 150

        -J(4)     -J(4)

C(2) = 150 - J(4)

6) to isolate just 1 C, divide everything by 2

{C(2) = 150 - J(4)} ÷ 2

C = 75 - J(2)

7) Go back to our original equation (in bold) and replace "C" with "75 - J(2)"

(75-J(2)-6) + J(4) + (75-J(2)) = 156

Now solve for J.

Thats as far as I got.

Answer: 257/16

Step-by-step explanation:

You are given the algebraic expression: m^4+ 1/m^4

if m− 1/m = 3

Solve for m by cross multiplying

m - 1 = 3m

Collect the likes terms

3m - m = -1

2m = -1

m = -1/2

Substitutes m into the algebraic expression above.

(- 1/2)^4 + 1/(- 1/2)^4

Open the bracket

1/16 + 1/(1/16)

1/6 + 16

16(1/16) or 257/16

Answer:

147

Step-by-step explanation:

We want to find the value of a² + √b, so let's plug in 12 for a and 9 for b:

a² + √b

12² + √9

The square root of 9 is 3 because 3 * 3 = 9, while the square of 12 is 144 because 12 * 12 = 144.

144 + 3 = 147

The answer is thus 147.

Answer:

w = 5

Step-by-step explanation:

Expand brackets.

-4w - 4 = -24

Add 4 on both sides.

-4w = -20

Divide both sides by -4.

w = 5

Answer:

w=5

Step-by-step explanation:

First, you do -4 times w and -4 times 1, which equals -4w+-4.

Then, you take -4 to the other side and it becomes -24+4=-20.

Now, you have -4w= -20

Lastly, you you divide -20/-4= 5.

w=5

Answers:

Step-by-step explanation:

17. We need to understand what an indirect proof is. In an indirect proof, you prove a statement by showing that the negation of the statement is false.

The "then" part of the conditional is the "to prove" statement.

In an indirect proof, we assume the opposite of what we want to prove, this is also called proof by contradiction.

So if we need to prove angle A is not an obtuse angle, we will assume it is and then use the proof format to show that angle A cannot be obtuse.

18. This question is asking us to use an indirect proof again. The "then" part of the statement is "KL > JK" and is the "to prove" statement.

We need the opposite of this, which would be assuming that KL < JK.

Answer:

17 inches

Step-by-step explanation:

The original square had sides of 4.5 (18/4)

To get a perimeter of 10, we know that two sides would already equal 9 (4.5+4.5).  That means we only have 1 inch for the other two sides, so they are each 1/2 inch.

That leaves the second rectangle with a length and width of 4.5 and 4.

2(4.5) + 2(4) =

Answer:

D

Step-by-step explanation:

not positive but i think it would be D

Option C is the distributions are positively skewed.

Since, A distribution that is positively skewed would have the following highlights:

More points on the left, if represented on a dot plot

Tall bars on the left, if represented on a histogram

Whisker on the left, if represented on a box plot

The above means that none of the distributions are positively skewed.

This is so because:

A is negatively skewed because the whisker is at the right

B and C are symmetrical because there are tall bars at the middle

D is positively skewed because the whisker is at the left.

Hence, Option D is the distributions are positively skewed.

The cross-section of the rectangular prism is a:

Step-by-step explanation:

When you take a cross-section of a rectangular prism, regularly you will obtain a rectangle because this was the base or the two-dimension figure that was used to form the three-dimension figure, in this case, the rectangular prism, the form of obtaining other figure is using how reference the square face, in that case, the cross-section would be a square, this happens because the cross-section is bind with the reference face. Possibly you think the cross-section in the figure doesn´t appear a rectangle, this happens by the perspective because we are looking at the rectangular prism with an inclination of 45°, but if the inclination was 90°, you would see a blue rectangle.

Step-by-step explanation:

Let x be that number.

4 + 3 × x = 19

4 + 3x = 19

Add -4 on both sides.

4 + 3x - 4 = 19 - 4

3x = 15

Divide both sides by 3.

(3x)/3 = 15/3

x = 5

Answer:

4+3x=19 so, x=5

19-4= 15, 15/3=5 or 5*3=15, 19-15=4.

Answer:

see explanations

Step-by-step explanation:

The given figure has four equal sides, and all adjacent sides are perpendicular to each other.

Quadrilateral is a any figure with four sides.

Particular quadrilaterals have specific names.

A square is a quadrilateral with equal sides, each perpendicular to the adjacent side, as shown in the figure.

A rectangle is a quadrilateral of which all sides are perpendicular to the adjacents.  Therefore opposite sides are equal.  Adjacent sides MAY or MAY NOT be equal.   Therefore a square is also a rectangle.

A rhombus is a quadrilateral of which all four sides are equal, but adjacent sides MAY or MAY NOT be perpendicular.  Therefore a square is also a rhombus.

A trapezoid (or trapezium, depending on which side of the atlantic you live) is a quadrilateral with AT LEAST one pair of parallel sides.  The other pair may or may not be equal, may or may not be parallel.  Therefore a square is also a trapezoid (trapezium).

A quadrilateral is any plane figure with four sides, which may or may not be parallel, may or may not be equal, and adjacent sides may or may not be perpendicular.  Therefore a square is also a quadrilateral.

So the given figure could be given all six possible names indicated in bold.  However, the name square is most specific.

Answer:

Step-by-step explanation:

 f(x) = a(b)^x + d

Answer:

The solutions the equation 1 are -1.3 and 2. The solutions to equation 2 are -1 and 0.

Step-by-step explanation:

Isolate the absolute value for equation 1. Then, set two equations equal to 5 and -5.

3x - 1 = 5  and   3x - 1 = -5  

Solve for x in both and you would get -1.3 and 2.

Do the same for equation 2.

2x + 1 = -1   and   2x + 1 = 1

Solve for x and you would get -1 and 0.

[tex]f(x) = 3x^2[/tex] and [tex]g(x) = x + 2[/tex]

Step-by-step explanation:

Given

[tex]h(x) = 3(x+2)^2[/tex]

[tex]h(x) = (fog)(x)[/tex]

Required

Find possible expressions for f(x) and g(x)

[tex]h(x) = (fog)(x)[/tex]

This can be rewritten as:

[tex]h(x) = f(g(x))[/tex]

Recall that [tex]h(x) = 3(x+2)^2[/tex]

So;

[tex]h(x) = f(g(x)) = 3(x+2)^2[/tex]

[tex]f(g(x)) = 3(x+2)^2[/tex]

By comparison, the expression in bracket represents g(x);

Hence;

[tex]g(x) = x + 2[/tex]

Replace g(x) with x

[tex]f(x) = 3(x)^2[/tex]

[tex]f(x) = 3x^2[/tex]

Hence, the possible expressions of f(x) and g(x) are:

[tex]f(x) = 3x^2[/tex] and [tex]g(x) = x + 2[/tex]
