How Do You Factor This?

Answers

Answer 1

Step 1. Split the second term in 2x^2 - x - 21 into two terms

2x^2 + 6x - 7x - 21

Step 2. Factor out the common terms in the first two terms, then in the last two terms.

2x(x + 3) -7(x + 3)

Step 3. Factor out the common term x + 3

(x + 3)(2x - 7)

Answers

The answer x = 11 is correct for problem 4. Nice work.

Use this x value to find the answer in problem 5. From problem 4, we're told that Romeo runs at a speed of 5 m/s. If he runs for x = 11 seconds,then he runs a total distance of:

5*x =(5 m/s)*(x meters) = (5 m/s)*(11 seconds) = 5*11 = 55 meters

The answer to problem five is 55 meters

B. y = -2x + 12

C. y = 1/2 x + 7

D. y = 2x + 4

Answers

The correct answer is C. y = 1/2x + 7

In order to find this, we first have to look for the slope. We can do that by using the slope formula below.

m(slope) = (y2 - y1)/(x2 - x1)

m = (8 - 6)/(2 - -2)

m = 2/4

m = 1/2

Now we can solve using the slope intercept form and a given point.

y = mx + b

8 = 1/2(2) + b

8 = 1 + b

7 = b

Now we can put these into the equation and model as y = 1/2x + 7

Solve |2x - 5| = 4. {x | x = -4.5 or x = 4.5} {x | x = 0.5 or x = 4.5} {x | 0.5 < x < 4.5}

Answers

Answer:

{x | x = 0.5 or x = 4.5}

Explanation:

Before we begin, remember that:

The modulus gives the positive value of what's inside it.

This means that:

|a| = |-a| = a

Now, for the given, we have:

|2x-5| = 4

From the above rule, we can deduce that:

either:

2x - 5 = 4

2x = 4 + 5 = 9

x = 4.5 ............> first solution

Or:

2x - 5 = -4

2x = 5-4 = 1

x = 0.5 ..........> second solution

Now, we check:

at x = 4.5: |2(4.5)-5| = |9-5| = |4| = 4 ..........> first solution verified

at x = 0.5: |2(0.5)-5| = |1-5| = |-4| = 4 .........> second solution verified

Hope this helps :)

-7 + y = 8

y= 15

elimination

Answer: It is best solve using elimination method

Step-by-step explanation:

4x + y = 1 --------(1)

2x + y = 8---------(2)

subtract (2) from (1)

2x = -7

divide bothside by 2

2x/2 = -7/2

x= -7/2

we can substitute x = -7/2 in any of the equations.

Lets take equation (1)

4x + y = 1

4(-7/2) + y =1

2(-7) + y = 1

-14 + y = 1

y = 1+14

y =15

If the measure of angle ABF=6x+26 and the measure of angle EBF=2x9 and measure of angle ABE= 11x-31 find the measure of angle ABF

Answers

Its not clearly given that whether EBF = 2x + 9 or 2x - 9.

I have written the solution for both.

If EBF = 2x + 9,

then ABF = 6x + 26 and ABE = 11x - 31.

Now, ABE = ABF + EBF

11x - 31 = (6x + 26) + (2x + 9)

           = (6x + 2x) + (26 + 9)

           = 8x + 35

11x - 8x = 35 + 31

3x = 66

x = 22

Therefore, ABF = 6x + 26 = 6(22) + 26 = 132 + 26 = 158°

If EBF = 2x - 9,

then ABF = 6x + 26 and ABE = 11x - 31.

Now, ABE = ABF + EBF

11x - 31 = (6x + 26) + (2x - 9)

           = (6x + 2x) + (26 - 9)

           = 8x + 17

11x - 8x = 17 + 31

3x = 48

x = 16

Therefore, ABF = 6x + 26 = 6(16) + 26 = 96 + 26 = 122°

The expression for angle ABF:  ABF = 6x + 26 = 6(16) + 26 = 96 + 26 = 122°

What is the angle

From the question: If EBF = 2x + 9, then ABF = 6x + 26 and ABE = 11x - 31.

When, ABE = ABF + EBF

11x - 31 = (6x + 26) + (2x + 9)

          = (6x + 2x) + (26 + 9)

          = 8x + 35

11x - 8x = 35 + 31

3x = 66

x = 22

Hence, ABF = 6x + 26 = 6(22) + 26 = 132 + 26 = 158°

When EBF = 2x - 9,

So, ABF = 6x + 26 and ABE = 11x - 31.

When, ABE = ABF + EBF

11x - 31 = (6x + 26) + (2x - 9)

          = (6x + 2x) + (26 - 9)

          = 8x + 17

11x - 8x = 17 + 31

3x = 48

x = 16

So,  ABF = 6x + 26 = 6(16) + 26 = 96 + 26 = 122°

which rule describes the composition of transformations that maps pre- image ABCD to final image A’’B’’C’’D’’ ?

Answers

In order to identify the transformations from ABCD to A''B''C''D'', carefully analyze changes in position and orientation. If, for instance, you observe a translation to the right by 3 units followed by a clockwise rotation of 90 degrees about point P, the rule in symbolic notation would be: T(3, 0) • R(P, 90)(x, y)

Identify the individual transformations:

Examine the image carefully and determine what transformations are involved in mapping ABCD to A''B''C''D''. Common transformations include translations (shifting), reflections (flipping), and rotations (turning).

Look for clues like changes in position, orientation, or direction to identify the transformations.

Analyze the order of transformations:

Determine the sequence in which the transformations were applied. This is crucial because the order affects the final result.

Look for intermediate images (like A'B'C'D' in your case) that show the effects of individual transformations.

Write the rule in symbolic notation:

Once you've identified the transformations and their order, use appropriate notation to express the composition rule.

Common notations include:

T(a, b) for translation by (a, b) units.

R(O, θ) for rotation about point O by θ degrees.

r(line) for reflection over a line.

Combine the notations for individual transformations using the composition symbol "•" to represent their sequential application.

If you determine that the transformations are a translation by (-6, 1) units followed by a reflection over the x-axis, the rule would be written as:

r(x-axis) • T(-6, 1)(x, y)

Complete question:

Which rule describes the composition of transformations that maps pre- image ABCD to final image A’’B’’C’’D’’ ?

Final answer:

The question seeks a description of the composition of geometric transformations mapping a pre-image to a final image, involving transformations such as translations, rotations, reflections, and dilations.

Explanation:

The question revolves around the concept of geometric transformations, specifically the composition of transformations as they apply to mapping a pre-image (ABCD) to a final image (A''B''C''D''). The composition of transformations includes operations such as translations, rotations, reflections, and dilations. To provide an accurate description of the rule that maps the pre-image to the final image, we would need to know the specific transformations applied in sequence. For instance, if ABCD was translated right by 5 units and then rotated about the origin by 90 degrees, the compositional rule would be a translation followed by a rotation.

Write an expression that shows how to use the halving and doubling strategy to find 28x50

Answers

Write an expression that shows how to use the halving and doubling strategy to find 28x50

Halving strategy means we divide by 2

Doubling strategy means we multiply by 2

We apply halving strategy for 28 and doubling strategy for 50

Half of 28 is 14

Double of 50 is 100

So 14 * 100 = 1400

Now we check with 28 * 50

28 x 50 = 1400

So required expression is

A local hamburger shop sold a combined total of 593 hamburgers and cheeseburgers on Thursday. There were 57 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on thursday

Answers

Answer:

325 hamburgers were sold on Thursday.

Step-by-step explanation:

Let h be the number of hamburgers and c be the number of cheeseburgers.

Using this information we can set up two equation as:

[tex]h+c=593\\c=h-57[/tex]

Now we need to solve these two equations to get the value of number of hamburgers. For that we use substitution method as shown below:

[tex]h+h-57=593\\2h-57=593\\2h=650\\h=325[/tex]

Therefore, the number of hamburgers sold on Thursday were 325.
