what does it mean translate the figure 5 units up

By definition. a Translation is a transformation in which a figure is moved a fixed distance in a fixed direction.

The Image is the figure obtained after the transformation and the Pre-Image is the original figure.

In this case, you know that the figure shown in the picture must be translated 5 units up. Therefore, the rule for this transformation is:

[tex](x,y)\rightarrow(x,y+5)[/tex]You can identify that the marked point on the Pre-Image has the following coordinates:

[tex]\mleft(-4,-3\mright)[/tex]Therefore, applying the rule for this transformation, you get that the coordinates of the marked point in the final figure, are:

[tex]\mleft(-4,-3\mright)\rightarrow\mleft(-4,-3+5\mright)\rightarrow(-4,2)[/tex]**The answer is:**

Write an equation in point-slope form of the line that passes through the given point and with the given slope m. A. (1, -8) m= -9

The point-slope form of a line is:

y = mx + b

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

Replacing with point (1, -8) and m= -9, we get:

-8 = (-9)(1) + b

-8 = -9 + b

-8 + 9 = b

1 = b

Then, the equation is:

Number 7 is the grey line. Number 8 is the red line

Mrs. Scott rented a jeep. The rental charge is a flat fee of

$115 plus $12.50 per hour. Her bill is $152.50, not

including tax. Write and solve an equation that could be

used to find the number of hours she rented the jeep

Answer is $152.50 = $12.50x + $115

Step by step

Using y intercept form

y = mx + b

Flat fee of $115 is y intercept or “b”

The $12.50 per hour is the rate or “m”

$152.50 is the total

So your equation is

$152.50 = $12.50x + $115

To solve subtract $115 from both sides to isolate x

$152.50 - $115 = $12.50x + $115 -$115

$152.50 = $12.50x

Divide both sides by $12.50 to solve for x

x = 12.2 hours

Step by step

Using y intercept form

y = mx + b

Flat fee of $115 is y intercept or “b”

The $12.50 per hour is the rate or “m”

$152.50 is the total

So your equation is

$152.50 = $12.50x + $115

To solve subtract $115 from both sides to isolate x

$152.50 - $115 = $12.50x + $115 -$115

$152.50 = $12.50x

Divide both sides by $12.50 to solve for x

x = 12.2 hours

When the hourly wage is $22, the time-and-a-half pay rate is $

(Simplify your answer.)

consequently, the **time and a half rate** will be 33 **dollars per hour** according to the query.

A higher rate of pay known as **"time and a half"** is normally only applied to hours that are over 40 in a workweek or that are worked extra.

Companies have different **overtime **pay practices, with time and a half as a typical **rate.**

Simply said, it means that for each hour performed within the time and a half window, the employee will receive payment in** addition** to their regular **hourly rate** of one half of that amount.

Time and a Half Rate = Hourly Rate * 1.5

According to the given question:

Time and a half rate =22$*1-1/2

=22$*1.5

=33$ per hour

Therefore, According to the question given the **Time and a pay half rate** will

be 33$ per hour.

can you help with these two questions please

The first question is relatively harder

So let’s start with that

Area of circle is 3.14(r^2)

We are given the diameter as 20m

So radius is 10m

Thus area = 3.14(100)= 314 sq metres

Now each box covers 58 sq metre

So no of boxes = 314/58= 5.41

Rounding to 1 significant figure

It’s 5 boxes

Clearly we are underestimating it as it’s around 5 boxes and a half

For the second question just equate their area

(11)(10)/2 = 22b

=> b= 2.5cm

So let’s start with that

Area of circle is 3.14(r^2)

We are given the diameter as 20m

So radius is 10m

Thus area = 3.14(100)= 314 sq metres

Now each box covers 58 sq metre

So no of boxes = 314/58= 5.41

Rounding to 1 significant figure

[tex]\begin{gathered} m_1\cdot m_2=-1 \\ -\frac{3}{4}\cdot m_2=-1 \\ m_2=\frac{4}{3} \end{gathered}[/tex]We replace the values of the point (-9, 6) and the slope to calculate the value of the y -intercept:

[tex]\begin{gathered} 6=-9\cdot\frac{4}{3}+b \\ b=12+6 \\ b=18 \end{gathered}[/tex]Therefore, the perpendicular equation that also passes through the point (-9,6) is:

[tex]y=\frac{4}{3}x+18[/tex]Now, when two lines are parallel, the slope is the same, therefore we calculate directly that it passes through the point (-9, 6)

[tex]\begin{gathered} 6=-9\cdot-\frac{3}{4}+b_{} \\ b=6+9\cdot-\frac{3}{4} \\ b=-\frac{3}{4} \end{gathered}[/tex]therefore, the equation of the line that is parallel to this line and passes through the point (-9, 6) is:

scores on an iq test are normally distributed. the test is designed so that the mean is 100 and standard deviation is 15. (a) what percentage of the population has an iq above 120?

From the **normal distribution** it is calculated that 9.18% of people has an iq over 120.

Normal distributions are crucial to **statistics **because they are widely used in the natural and social sciences to represent real-valued regressors with unknown distributions.

We have to find P( X > 120 )

Thus find** z score** for x =120

[tex]z=\frac{x-\mu}{\sigma}=\frac{120-100}{15}=\frac{20}{15}=1.33[/tex]

Thus we get:

P(X>120) = P(Z>1.33)

P(X>120) = 1 - P(Z<1.33)

P( Z < 2.67) = 0.9082

Thus

P(X>140) = 1 - P(Z<2.67)

P(X>140) = 1 - 0.9082

P(X>140) = 0.0918

Percentage = 9.18%

Therefore 9.18% of people has an iq over 120.

In the diagram given, there are two **parallel lines** and three angles formed by cutting the parallel lines.

So here, angles** (2x+7)°** and **(3x-7)° **are **corresponding angles.**

That is they occupy relatively same position, that is both are above each **parallel line.**

So they are equal angles.

i.e., 2x+7 = 3x-7

⇒ 3x-2x = 7 +7

⇒ **x = 14**

Now the angles **2x+7°** and** 12y+1°** are **supplementary angles.**

**Supplementary angles** are formed on a straight line between a line cutting the straight line.

That is their sum = 180°

i.e., 2x+7° + 12y+1° = 180

⇒ 2 x 14 + 7 + 12y +1 = 180

⇒ 28 + 8 +12y = 180
