f(x) = 3x + 7. What is f(4) ?

Answer: 100

Step-by-step explanation: BRAINLIEST

Step-by-step explanation:

This means the price of the book will decrease by 100%-30%=70%

70% decrease in x = 100% of x - 70% of x = 1x - 0.7x = (1 - 0.7)x = 0.3x So 0.3x represents a 70% decrease in x.

Notice that this multiplier .3 is the same as (30% of x).

the answer is 0.3.

Answer:

The correct answer would be 40

Step-by-step explanation:

40+60=100

The measure of angle x will be 145° so option (C) will be correct.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

Since we lack a measurement for angular rotation, the angle is a valuable tool for measuring angular distance. For instance, a meter or an inch is a unit of measurement for linear motion.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

The angle all around the line is 360°.

The angle 165°, 50°, and x consist total of 360°.

165 + 50 + x = 360

x = 145°.

So the angle of x will be 145°.

Answer:

  C.  35.3 km

Step-by-step explanation:

From your knowledge of right triangles, you know that the hypotenuse is longer than the longest leg and shorter than the sum of the legs.

For this geometry, the distance of interest is longer than 32 km and shorter than 15+32 = 47 km. The only answer choice in the correct range is ...

  35.3 km

Answer:

The x-intercepts are 1 and 3

The y-intercept is 3

The vertex is (2,-1)

The line of symmetry is x=2

Step-by-step explanation:

To find the x-intercepts, find where the graph intersects the x-axis, or the horizontal line. To find the y-intercept, find where the graph intersects the y-axis, or the vertical line. To find the vertex, find the coordinate where the graph is at its lowest point (or highest if it is flipped upside down). To find the line of symmetry, simple use the x-coordinate of the vertex and say x= (the x-coordinate)

Answer:

 The vertex of the parabola   = (-7 , -4)  

Step-by-step explanation:

Step(i):-

Given that the parabola  y = 4 x² + 56 x +192

                                 y = 4 (x² + 14 x + 48 )

                                 y = 4 ( x² + 2 ×  7 (x) + 49-1)

                                 y = 4 ( x² + 2 ×  7 (x) + 49)- 4

we apply the formula

(a +b)² = a² + 2ab + b²

                                y = 4 ( x + 7 )² - 4

Step(ii):-

The general form of the parabola in algebraically

                              y = a ( x-h)² +k

The equation

                          y = 4 ( x + 7 )² - 4

                          y = 4 ( x-(-7))² - 4

  The vertex of the parabola (h,k) = (-7 , -4)  

Final answer:-

The vertex of the parabola  = (-7 , -4)

Answer:

Mean: $16.1

Median: $15.00

Mode:$15.00

The mode best describes the data, so the mean is the better measure of variability.

Step-by-step explanation:

How to find the mean:

Add up each value on the data set, then divide it by the number of values on the data set. (Example: $17.00 + $15.50+$15.00+$18.00+$15.00= 80.5/5=16.1)

How to find the median: Order your values from least to greatest, then find the value in the center.

How to find mode: Look for the most frequent value in the data set. What value shows up the most?

Hence, the mean is $ [tex]16.1[/tex] and the median is $ [tex]15.50[/tex] and the mode is $ [tex]15.00[/tex].

Here, the mode best describes the data, so the mean is the better measure of variability.

What is the mean, median, mode?

Mean, median, and mode are the measures of central tendency, used to study the various characteristics of a given set of data. A measure of central tendency describes a set of data by identifying the central position in the data set as a single value.

Here given data is

$[tex]17.00[/tex], $[tex]15.50[/tex], $[tex]15.00[/tex], $[tex]18.00[/tex], $[tex]15.00[/tex]

Here,

Mean is the sum of all values divided by number of observation

i.e,

[tex]\frac{17.00+15.50+15.00+18.00+15.00}{5}=\frac{80.5}{5}\\\\\\=16.1[/tex]

Median is the middle value of the data, firstly we arrange the data in ascending order

[tex]15.00,15.00,15.50,17.00,18.00[/tex]

So, the middle value is [tex]15.50[/tex] $.

Mode is the repetition of the same number in the data

[tex]15.00,15.00,15.50,17.00,18.00[/tex]

Then, [tex]15.00[/tex] is the mode of the given data.

Hence, the mean is $ [tex]16.1[/tex] and the median is $ [tex]15.50[/tex] and the mode is $ [tex]15.00[/tex].

Here, the mode best describes the data, so the mean is the better measure of variability.

Answer:x=5 or x=−5

Step-by-step explanation:

4x^2−100=0

Step 1: Add 100 to both sides.

4x^2−100+100=0+100

4x^2=100

Step 2: Divide both sides by 4.

4x^2/4=100/4

x^2=25

Step 3: Take square root.

x=±√25

x=5 or x=−5

Answer:

x=5 or x=−5

he slept for 1/2 of the trip and then slept have the distance that was left so that would be 1/2 divided by 2 equals 1/4 so 1/2 plus 1/4 equals 3/4 so george has 1/4 of his journey left.

George was asleep for 33.3% of the journey.

When George went to sleep, he was halfway through to his grandmother's house which means that he was left with 1/2 of the journey.

When he woke up, he was still left with half of the distance he had slept. If we made this an expression and assume the percentage of the journey he slept was x, it would be:

1/2 of the journey = 1/2x + x

1/2 = 1.5x

x = 1/2 ÷ 1.5

x = 33.3%

George therefore fell asleep for 33% of the journey.

Step-by-step explanation:

The desired rate is ...

  "unit rate" = cost/T-shirt = $180/(12 T-shirts) = $15/T-shirt
