Step-by-step explanation:
To solve the inequality:
-3 > 5 - b
We can start by isolating the variable b on one side of the inequality. We can do this by subtracting 5 from both sides of the inequality:
-3 - 5 > -b
Simplifying the left-hand side of the inequality, we get:
-8 > -b
To isolate b, we can multiply both sides of the inequality by -1. When we do this, we need to reverse the inequality sign:
8 < b
So the solution to the inequality is:
b > 8
This means that b must be greater than 8 for the inequality to be true.
which of the following functions represent the graph g(x) above
The function represented by the graph given is equivalent to -
g(x) = (x - 4)².
The function plotted represents a quadratic equation. A quadratic equation has a degree of 2. The given function is shifted to the left by 4 units. This means that the following transformation will take place on the x - coordinate of each and every point lying on the graph -
f(x, y) → f(x - 4, y)
So, we can write the function as -
g(x) = (x - 4)²
So, the function represented by the graph given is equivalent to -
g(x) = (x - 4)²

8. Write a paragraph proof.
Proof Given: In a plane, a is perpendicular to b, b id perpendicular to c, and c || d.
Prove: a || d
To prove that line segment a is parallel to line segment d, based on the given information, we can utilize the properties of perpendicular and parallel lines.
Given that a is perpendicular to b and b is perpendicular to c, we know that angles formed between a and b, as well as between b and c, are right angles. Let's denote these angles as ∠1 and ∠2, respectively.
Now, since c is parallel to d, we can conclude that the corresponding angles ∠2 and ∠3, formed between c and d, are congruent.Considering the fact that ∠2 is a right angle, it can be inferred that ∠3 is also a right angle.
By transitivity, if ∠1 is a right angle and ∠3 is a right angle, then ∠1 and ∠3 are congruent.Since corresponding angles are congruent, and ∠1 and ∠3 are congruent, we can deduce that line segment a is parallel to line segment d.
Thus, we have successfully proven that a is parallel to d based on the given information and the properties of perpendicular and parallel lines.

Simplify: 5 2/5x-1/3(x+3/4y)-y+3/8y
Answer:
(608 x - 105 y)/120
Step-by-step explanation:
Simplify the following:
(3 y)/8 - y - 1/3 (x + (3 y)/4) + (5 + 2/5) x
Put each term in (3 y)/4 + x over the common denominator 4: (3 y)/4 + x = (3 y)/4 + (4 x)/4:
(5 + 2/5) x - (((3 y)/4 + (4 x)/4))/3 - y + (3 y)/8
(3 y)/4 + (4 x)/4 = (3 y + 4 x)/4:
(5 + 2/5) x - ((1/4 (3 y + 4 x)))/3 - y + (3 y)/8
4×3 = 12:
(5 + 2/5) x - (3 y + 4 x)/12 - y + (3 y)/8
Put 5 + 2/5 over the common denominator 5. 5 + 2/5 = (5×5)/5 + 2/5:
((5×5)/5 + 2/5) x - (3 y + 4 x)/12 - y + (3 y)/8
5×5 = 25:
(25/5 + 2/5) x - (3 y + 4 x)/12 - y + (3 y)/8
25/5 + 2/5 = (25 + 2)/5:
((25 + 2)/5) x - (3 y + 4 x)/12 - y + (3 y)/8
25 + 2 = 27:
(27 x)/5 - (3 y + 4 x)/12 - y + (3 y)/8
Put each term in (27 x)/5 - (3 y + 4 x)/12 - y + (3 y)/8 over the common denominator 120: (27 x)/5 - (3 y + 4 x)/12 - y + (3 y)/8 = (648 x)/120 + (10 (-3 y - 4 x))/120 - (120 y)/120 + (45 y)/120:
(648 x)/120 + (10 (-3 y - 4 x))/120 - (120 y)/120 + (45 y)/120
(648 x)/120 + (10 (-3 y - 4 x))/120 - (120 y)/120 + (45 y)/120 = (648 x + 10 (-3 y - 4 x) - 120 y + 45 y)/120:
(648 x + 10 (-3 y - 4 x) - 120 y + 45 y)/120
45 y - 120 y = -75 y:
(648 x + 10 (-3 y - 4 x) + -75 y)/120
10 (-3 y - 4 x) = -30 y - 40 x:
(648 x + (-30 y - 40 x) - 75 y)/120
Grouping like terms, -30 y - 75 y + 648 x - 40 x = (648 x - 40 x) + (-30 y - 75 y):
((648 x - 40 x) + (-30 y - 75 y))/120
-30 y - 75 y = -105 y:
(-105 y + (648 x - 40 x))/120
648 x - 40 x = 608 x:
Answer: (608 x - 105 y)/120
The solution of equations system using the Substitution Method
y = 3x & 2y+2x=24 is (3,9)
true
or
false
help mee
Answer:
True
Step-by-step explanation:
\( \begin{cases} y = 3x \\\\ 2y + 2x = 24\end{cases} \)
Plugging y = 3x in the equation 2y + 2x = 24, we find:
2(3x) + 2x = 24
6x + 2x = 24
8x = 24
x= 24/8
x = 3
Plugging x = 3 in the equation y = 3x we have:
y = 3*3 = 9
(x, y) = (3, 9)

What does it mean to have a skewed distribution? What causes
a skew in statistical terms? And how does one deal with skewed
data when conducting research? Are there specific types of
research questions and types of data where one would expect
the data to be skewed?
Answer:
Explained below.
Step-by-step explanation:
A) A skewed distribution in a dataset is when the median is not equal to the mean in such a manner that the bell curve is tilted to the left or right.
B) If in a data set, there are outliers which are extremely large or extremely small in comparison to other values in that same dataset, then we can say that such a curve will be pulled towards the outlier and thus the distribution is skewed.
Also, if the curve is inclined to the left, it means there are few extreme values to the left and is is negatively skewed.
Similarly, if the curve is inclined to the right, it means there are few extreme values to the right and is positively skewed.
C) Example of a research question is;
If in a developed country where the poverty level is about 0%, if we collect the data of income of the households, we will discover majority of people with average income and very few people with extreme high levels of income. This condition means the data to is positively skewed.
Which statement about the slope of the line is true
Check the picture below.
of course, that's the slope simplified, now, taking a peek at the non-simplified slopes that are shaded, the larger triangle will have a larger "run" and a larger "rise" and thus a larger slope than the smaller one.
So we can say that from the origin to A, the non-simplified slope is larger than from A to B.

Answer:
a) 7 m
b) 22 cm
Step-by-step explanation:
Given plans at a scale of 1 : 50, you want (a) the actual length corresponding to a plan length of 14 cm, and (b) the plan length corresponding to an actual length of 11 m.
ProportionThe actual lengths are wanted in meters, so we can rewrite the scale to translate between plan cm and actual m.
plan : actual = 1 cm : 50 cm
= 1 cm : 0.5 m
= 2 cm : 1 m
a) 14 cmMultiplying the scale by 7, we have ...
2 cm : 1 m = 14 cm : 7 m
The actual length is 7 meters.
b) 11 mMultiplying the scale by 11, we have ...
2 cm : 1 m = 22 cm : 11 m
The plan length is 22 cm.

was 10°C higher than the temperature at
8:00 A.M. What was the temperature at
8:00 A.M.?
The temperature at 8:00 A.M. was 15°C.
Using the given information:
1. At 7:00 P.M., the temperature was 16°C.
2. This temperature was 9°C less than the temperature at 2:00 P.M.
We can use this information to find the temperature at 2:00 P.M.:
Temperature at 2:00 P.M. = 16°C (temperature at 7:00 P.M.) + 9°C
Temperature at 2:00 P.M. = 25°C
3. The temperature at 2:00 P.M. was 10°C higher than the temperature at 8:00 A.M.
Now, we can find the temperature at 8:00 A.M.:
Temperature at 8:00 A.M. = 25°C (temperature at 2:00 P.M.) - 10°C
Temperature at 8:00 A.M. = 15°C
