Step-by-step explanation:
What value of x satisfies the equation 5(x – 3) – 2(x + 1) = 4?
Answer:
x = 7
Step-by-step explanation:
To solve:
Distribute 5 among everything inside the first parentheses. You'll get 5x - 15.
Next distribute -2 among everything in the second parentheses. You'll get
-2x - 2.
All together: 5x - 15 -2x - 2 = 4
Now combine like terms:
5x - 2x = 3x and -15 - 2 = - 17
All together: 3x - 17 = 4
Add 17 on both sides to get 21, and then divide both sides by 3. Answer is x = 7.
________________________________
Last, don't forget to check your work.
You can plug in 7 for x to get:
5(7 - 3) = 20
5 × 7 = 35
5 × -3 = -15
35 - 15 = 20
-2(7 + 1) = -16
-2 × 7 = -14
-2 × 1 = - 2
-14 -2 = -16
20 - 16 = 4
⬆⬆⬆Therefore this is correct.

Find the measure of angle 1.
8x - 4
16x + 8
Answer:
53°
Step-by-step explanation:
As we can see that ∠3 and ∠7 are corresponding angles. Therefore,
∠3 = ∠76x+8 = 8x-76x-8x = -7-8-2x = -15x = -15/-2x = 15/2Now calculate the angles of ∠3 and ∠7.
∠36x+86×15/2+845+853°∠78x-78×15/2-760-753°Now we can see that ∠3 and ∠1 are alternate angles and ∠7 and ∠1 are alternate exterior angles. Thus, we can say that
∠3 = ∠7 = ∠1 = 53°Hence the measure of ∠1 is 53°.

Alicia wants a pair of shoes that cost $68.48. If 17% sales tax must be added to the price, approximately
how much will the shoes cost including sales tax?
Answer:
$80.12; approx. $80
Step-by-step explanation:
- multiply 68.48 x 17% or 68.48 x 0.17 = 11.64
- the tax is 11.64
- add 68.48 + 11.64
- her total is $80.12
- rounded it would be $80

*** Which statement best describes the explanatory and response variables in the regression model?
O In the quadratic regression model, the explanatory variable is time and the response variable is the height.
O In the quadratic regression model, the explanatory variable is the height and the response variable is time.
O In the trigonometric regression model, the explanatory variable is time and the response variable is the height.
O in the trigonometric regression model, the explanatory variable is the height and the response variable is time.
Answer:
A. In the quadratic regression model, the explanatory variable is time and the response variable is the height.Step-by-step explanation:
The explanatory variable (or the independent variable) always belongs on the x-axis (represented as the first column of the table).
The response variable (or the dependent variable) always belongs on the y-axis (represented as the second column of the table).
According to the explanation above the correct choice is A
Answer:
C: In the trigonometric regression model, the explanatory variable is time and the response variable is the height.
Step-by-step explanation:
A quadratic regression model is a parabola. If time is x and height is y, it doesn't make sense if the height is 3,600 feet after a minute. (Not to scale) A trigonometric regression model is a sine wave like a sound wave. This makes sense because the Ferris wheel can only go so high. So after a minute, the height might be 8 feet. (Not to scale)
An explanatory variable is what what you manipulate or observe changes in.
A response variable is what changes with the explanatory variable.
For example, age would be an explanatory variable while height would be the response variable. Or, a caffeine dose would be explanatory, while say reaction time would be the response.

Step-by-step explanation:
fx = −1 3
x 7 x+ 7
-------------------------
x x
f= -x+3
7x
f= -x+3
7x
Answer:
A.
Step-by-step explanation:
f(x) = (3-x)/7
First we find x in terms of f(x:-.
7f(x) = 3 - x
x + 7f(x) = 3
x = 3 - 7f(x)
Now we replace x by f-1(x) and f(x) by x:
f-1(x) = 3 - 7x.
Ally's science class was looking at bacteria through a microscope. Ally's teacher said some bacteria can be as small as 0.00365 cm long. What is the length of the bacteria written in scientific notation?
The length of the bacteria should be written in scientific notation.
0.00365 in scientific notation = 3 × 10^-3
Given.
length of the bacteria in decimal = 0.00365 cm long
Scientific notation is written in the format x × 10ⁿ
where,
x = any number between digit 1 and 10
n = exponent (positive or negative).
To have a negative exponent value, move decimal to the rightTo have a positive exponent value, move the decimal point to the left.In this case, the nearest significant value is 3
So move the decimal point three times to where 3 is
That is,
0.00365 = 3.65
Since the decimal point is moved to the right 3 times, n = - 3
we have 10^-3
Therefore,
0.00365 in scientific notation = 3 × 10^-3

Answer:
Surveying To approximate the length of a marsh, a surveyor walks 250 meters from point to point , then turns and walks 220 meters to point (see figure). Approximate the length of the marsh.
hope it helped
Step-by-step explanation:
The approximate length of the lake is 625 yards.
Given that, a surveyor starts at one end of the lake and walks 245 yards.
What is total?A total is a whole or complete amount, and "to total" is to add numbers or to destroy something. In math, you total numbers by adding them: the result is the total.
He then turns 110 and walks 270 yards until he arrives at the other end of the lake.
Total length of the lake is
245+110+270 =625 yards
Therefore, the approximate length of the lake is 625 yards.

60 students are divided into equal groups of 5 student each.
Groups of 5 students per group totaled up to 60 students.
The quotient in both expression is 60:5 = 12 students per group.

The ratio expression is a way of expressing the division of numerator by a denominator.
Here,
The total number of students is the numerator = 60
The denominator is the number of students per group = 5
Hence, the quotient is the value of the divison obtained which is (60/2) = 12
