Answer:

2x+2

Step-by-step explanation:

Perimeter = 2 * width + 2 * length

12x+10 = 2(4x+3) + 2 * width

12x+10 = 8x + 6 + 2w

4x+4 = 2w

2x+2 = w

Answer:

[tex]x=\frac{1+\sqrt{21}}{2}\approx 2.79\\or\ x=\frac{1-\sqrt{21}}{2}\approx -1.79[/tex]

Step-by-step explanation:

Given

Quadratic equation is

[tex]x^2-x-2=3\\x^2-x-5=0[/tex]

Roots of the quadratic equation [tex]ax^2+bx+c=0[/tex] are

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\[/tex]

So, for the given equation roots are

[tex]x=\frac{1\pm\sqrt{(-1)^2-4(1)(-5)}}{2\cdot 1}\\x=\frac{1\pm\sqrt{21}}{2}\\so, x=\frac{1+\sqrt{21}}{2}\approx 2.79\\or\ x=\frac{1-\sqrt{21}}{2}\approx -1.79[/tex]

Answer:

Any number that isn't 3.

Step-by-step explanation:

Any other number should work, so I'll just show you what happens if you use 3.

2(3x - 2) = 6x + 5

6x - 4 = 6x + 5

-4 ≠ 5

As you are aware, that would make it no solution hence why it can't be used.

Answer:

x = 5

Step-by-step explanation:

Since the problem shows us that all the angles of the triangle are equal, we can confirm this is an equilateral triangle. Equilateral triangles have the same angles and the same side lengths. Knowing this, we can set up an equation to solve for x.

6x - 5 = 5x (Given)

-5 = -x (Subtract 6x on both sides)

5 = x (Divide -1 on both sides)

Therefore, x = 5.

Answer:

x = 5

Step-by-step explanation:

Since all the three angles of the triangle GJH are marked by identical signs, thus they are congruent.

Therefore, triangle GJH is an equilateral triangle.

Measures of all sides of an equilateral triangle are equal.

So,

6x - 5 = 5x

6x - 5x = 5

x = 5

Answer:

We have a slope and a point, this way, we do not need to find the slope using two points. We can find the line using the Slope Form to turn it into Slope-Intercept Form, also known as "y = mx + b". We can use the Slope Form which is "y - y1 = m(x - x1)". A coordinate is "(x,y)", so that means, "(-1,4)" means that x = -1 and y = 4. We can substitute y1 for 4 and x1 for -1, and m for -5 since m is the slope. Plugging that information into the Slope Form Formula we get "y - 4 = -5(x - (-1))". We know that a negative with a negative turn positive, so we can use this information to change the formula to "y - 4 = -5(x + 1)". Now we distribute and simplify, these steps are shown below.

y - 4 = -5(x + 1)

y - 4 = -5x -5

y - 4 + 4 = -5x - 5 + 4

y = -5x - 1

Now that we have simplified it, we can see that the slope is -5 and the -1 is the y-intercept. To check this is a linear equation is to graph it, or substitute three x-coordinate or y-coordinates and draw a line. In conclusion, the equations is y = -5x - 1.

The correct answer is Option C:

{140, 140, 140, 140, 140, 140, 165, 165, 165, 165, 165, 170, 170, 180, 180, 180, 180}

Step-by-step explanation:

Dot plots are one of the tools that are used to represent data in statistics and mathematics.

As the dot plot is given, we can make the data set from the plot.

As we can see that there are 6 dots above the value 140 that means 140 occurs 6 times in the data set.

Similarly, 165 occurs 5 times, 170 two times and 180 four times.

So the dataset will be:

{140, 140, 140, 140, 140, 140, 165, 165, 165, 165, 165, 170, 170, 180, 180, 180, 180}

[tex]a = \frac{5}{12} \\ b = \frac{1}{8} [/tex]

Substitute a = 5/12 and b = 1/8 in the expression.

[tex]2( \frac{5}{12} ) + \frac{1}{8} \\ \frac{5}{6} + \frac{1}{8} [/tex]

Our denominator must be 24. (LCM)

Answer:

$3.75

Step-by-step explanation:

2/3 = $2.50

2.50/2 = 1.25

1.25x3 = 3.75

The price of the triple pack of gum is $3.75.

Since Bailey brought a twin pack of gum for $2, this is 50 cents less than 2/3 the cost of a triple pack of gum.

So,

[tex]2\div 3 = \$2.50\\\\2.50\div 2 = 1.25\\\\1.25\times 3 = 3.75[/tex]

Answer:

We conclude that the equation of a linear function with f (5) = -1 and f(0) = -5 will be:

Step-by-step explanation:

Given

f(5) = -1 means at x = 5, y = -1

Hence, the point (5, -1) lies on the line function.

f(0) = -5 means at x = 0, y = -5

Hence, the point (0, -5) lies on the line function.

Thus, the two points on the linear line function graph are:

Finding the slope between the points (5, -1) and (0, -5)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:-5\right)[/tex]

[tex]m=\frac{-5-\left(-1\right)}{0-5}[/tex]

[tex]m=\frac{4}{5}[/tex]

The slope-intercept form of the linear line function

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

We have already determined the slope which is: m = 4/5

We know the y-intercept can be determined by setting x = 0 and solving for y.

Thus, the point (0, -5) represents the y-intercept b = -5.

Now, substituting m = 4/5 and b = -5 in the slope-intercept form

[tex]y = mx+b[/tex]

y = 4/5x + (-5)

y = 4/5x - 5

Therefore, we conclude that the equation of a linear function with f (5) = -1 and f(0) = -5 will be:

Question:

Abdulla took a takie from his home to the air port. The taxi driver chared an initial fee of 12AED pluse 2.50AED per km. How much change should the taxi driver give mr abdulla bach if he gave him 100AED at the end of his trip

Answer:

88 - 2.50x

Step-by-step explanation:

Given :

Initial charge = 12

Charge per kilometer = 2.50

Amount given to driver = 100

Let distance from home to airport = x

Total charge = (initial charge + (distance * charge per km)

Total charge = 12 + 2.50x

Change = (Amount given to driver - total charge)

Change = (100 - (12 + 2.50x))

100 - 12 - 2.50x

88 - 2.50x

Answer:

Step-by-step explanation:

Given the expression
