Answer:
x = 15
Step-by-step explanation:
x + 2y = 37
x - y = 4
x + 2y = 37
2x - 2y = 8
3x = 45
x = 15
Steps:
1. Isolate y in the equation x - y = 4
x - y = 4
-y = 4 - x
y = 4 - x / -1
2. Substitute value of x (15) into the new equation y = 4 - x / -1
y = 4 - 15 / -1
y = -11 / -1
y = 11
3. Plug in your y value (11) and x value (15) into the equation x + 2y = 37
15 + 2(11) = 37
15 + 22 = 37
37 = 37 ✅
4. Plug in your y value (11) and x value (15) into the equation x - y = 4
15 - 11 = 4
4 = 4 ✅
both equations are true with the value of x being 15 therefore your answer is
(4) x = 15

Answer:
(a) $2.857 million
(b) vertical compression by 1/3; shift left by 6; shift up by 2
Step-by-step explanation:
(a) Find the year difference (2021-2010=11) and put that value where x is. Then do the arithmetic.
g(11) = (∛(11+6))/3 +2 = (∛17)/3 +2 ≈ 2.57128/3 +2 ≈ 0.857 +2
g(11) ≈ 2.857 . . . 2021 revenue in millions of dollars
__
(b) For parent function f(x), the transformation ...
g(x) = a·f(x -h) +k
represents a vertical scaling by a factor of 'a', right shift by h units, and up shift by k units.
Comparing this form to the given g(x), we see ...
a = 1/3 . . . vertical compression by a factor of 1/3
h = -6 . . . .right shift 6 units
k = 2 . . . . up shift 2 units
_____
Additional comment
The vertical scaling is called "compression" when the scale factor is less than 1, and "stretch" when the scale factor is greater than 1. Here, the scale factor of 1/3 means the graph is vertically compressed.

What is the missing term? What is the rule? 8 9/10, 7 7/10, 6 1/2 , _________
Answers
Answer:
5 3/10
Step-by-step explanation:
You subtract 1 1/5 from the number (n).
(In equation) x = n - 1 1/5
The rule is to subtract 1 2/10 each time
To figure this out, first look at the whole numbers
8, 7, 6, ___
You can see that your subtracting one to get to the next number.
Now look at the fractions.
9/10, 7/10, 1/2
To figure out the change you want all the fractions to have the same denominator.
1/2 = 5/10
9/10, 7/10, 5/10, ___
You can now also see that 2/10 is being subtracted each term.
Adding the two changes you get 1 + 2/10 = 1 2/10
The distance in miles that some students live from school is show in the histogram which stamen about the data in the histogram is true
Answers
Answer:
D). The distribution of the data is symmetrical, so the mean and median are within the "2.1-3 mile" category.
Step-by-step explanation:
The last statement i.e. 'The distribution..."2.1-3 mile" category' correctly asserts a true claim regarding the data provided in the given histogram. It aptly states that the dissemination of the data is uniform(2, 4, 5, 4, 2(no. of students) live between the distance of 0.1 to 5 miles from the school) and this causes both the mean, as well as, the median of the distribution to fall in the category between '2.1 to 3 mile.' Thus, option D is the correct answer.

Angle DEF is similar to angle JKL.Find the length of JL and KL? First triangle DF 12.4cm DE 4cm EF 9cm other triangle JK 3cm JL ? KL ?
Answers
Answer:
KL = 6.75cm
JL = 9.3cm
Step-by-step explanation:
SInce Angle DEF is similar to angle JKL.
Then;
DE/EF = JK/KL
Given
DE = 4cm
JK = 3cm
EF = 9cm
Substitute
4/9 = 3/KL
4KL = 27
KL = 27/4
KL = 6.75cm
Similarly
DF/EF = JL/KL
12.4cm/9 = JL/6.75
9JL = 12.4 * 6.75
9JL = 83.7
JL = 83.7/9
JL = 9.3cm
