Step-by-step explanation:
multiply: -4 (8x) - 4 (12y) = -32x-48y
Answer:
32x - 48y
Step-by-step explanation:
when you distribute, -4 has to go to both -8x and 12y
so -4 times -8x = 32x
-4 times 12 = -48y

According to the stem-and-leaf plot above, how many drivers travel below 80 miles hour per hour? A. 2 B. 6 C. 14 D. 5
Answers
Answer:
See Explanation
Step-by-step explanation:
Given
The question is incomplete, as the required stem-and-leaf plot is not available. I will answer this question with the attached plot
Required
Drivers that travel below 80 mph
A stem and leaf plot has the following syntax: Stem | Leaves
Take for instance:
7 | 2 3 4 7
The above represents 72, 73, 74 and 77
Using the above illustration, the attached leaf plot can be interpreted as:
60, 61, 61, 65, 66, 66, 67
71, 73, 76, 77, 78
80 81... and so on
The drivers that drive below 80 mph are:
60, 61, 61, 65, 66, 66, 67
71, 73, 76, 77, 78
And the frequency is: 12
Hence, 12 drivers travel below 80 mph (using the attached stem and leaf plot)

Hope it helped :)the following image is a trapazoid.if XW is congruent YZ and measaure of m = 72 degrees. calculate the measure of X
Answers
Answer:
opposite angle of trapezoid is supplementary
<Z+<X=180°
<X=180°-72°
<x=108°
is your answer
The required value of the measure of the angle x is 108°. Option A is correct.
The following image is a trapezoid. if XW is congruent to YZ and measure of m = 72 degrees. calculate the measure of X is to be determined.
The angle can be defined as the one line inclined over another line.
What is a trapezoid shape?A trapezoid is defined as a quadrilateral with one couple of opposite sides parallel. the sum of the opposite angles is 180. Only one pair of opposite sides should be parallel not all the sides if all sides are parallel then the shape became a rectangle or rhombus.
Since the sum of the opposite angles in trapezoids is 180°
so,
x + 72° = 180°
x = 180° - 72°
x = 108°
Thus, the required value of the measure of the angle x is 108°.

Describe the trend/correlation
shown in the scatter plot below
Answers
Answer:
Negative correlation.
Step-by-step explanation:
Negative correlation means that as x increases, y decreases
Positive correlation means that as x increases, y also increases.
No correlation means that neither of the two above cases happens.
In the graph, we can see that on the right (when x is negative) the general y values are larger.
As x increases, the y-values decrease.
(Particularly, we could adjust these data with a linear equation with a negative slope)
Then this is a negative correlation.

Answer:
area = 82 cm²
Step-by-step explanation:
The figure comprises a trapezoid, a triangle and a square.
Calculating areas of the three shapes separately and then adding them will give us the required area of the composite figure.
Area of square : (side)²
= (2)²
= 4 cm²
Area of triangle : ½ × b × h
= ½ × 3 × 12
= 3 × 6
= 18 cm²
Area of trapezoid : ½ × (a + b) × h
= ½ × (5+5) × 12
= ½ × 10 × 12
= 5 × 12
= 60 cm²
Now, area of the composite figure :
= 4 + 18 + 60
= 22 + 60
= 82 cm²
Answer:
82 cm²Step-by-step explanation:
If you exclude the square on the bottom, you have a trapezoid with bases of 5 cm and 8 cm and the height of 12 cm.
Its area is:
A = (5 + 8)*12/2 = 78 cm²Add the area of the square with sides of 2 cm:
A = 2*2 = 4 cm²Total area is:
A = 78 + 4 = 82 cm²How do you calculate this?

The 15th term of an arithmetic sequence is 21 and the common difference is -4.
(a) Find the first term of the sequence.
(b) Find the 29th term of the sequence.
(c) Find the sum of the first 40 terms of the sequence.
Answers
Answer:
a. Firat term of the sequence= 77
b. 29th term of the sequence= -35
c. Sum of the first 40 terms of the sequence= -40
Step-by-step explanation:
The first term of the sequence is 77, the 29th term of the sequence is -35 and the sum of the first 40 terms of the sequence is -40.
Given that, [tex]a_{15} =21[/tex] and d=-4.
What is the nth term of the arithmetic sequence?The nth term of the arithmetic sequence is [tex]a_{n} =a+(n-1)d[/tex].
To find the first term of the sequence:
[tex]a_{15}[/tex]=a+(15-1)(-4)
⇒21=a+(15-1)(-4)
⇒a=77
To find the 29th term of the sequence:
[tex]a_{29}[/tex]=77+(29-1)(-4)=-35
To find the sum of the first 40 terms of the sequence:
The first n terms of a sequence [tex]=\frac{n}{2}[2a+(n-1)d)][/tex]
[tex]S_{40} =\frac{40}{2}[2 \times77+(40-1)(-4))][/tex]
=20(154-156)=-40
Therefore, the first term of the sequence is 77, the 29th term of the sequence is -35 and the sum of the first 40 terms of the sequence is -40.
