Answer:
The correct option is;
1, 6, 11, 15
Step-by-step explanation:
The given information are;
The function that defines the terms of the sequence is f(n) = f(n - 1) + 5
Where;
n = The number of the term
For n = 1, we have, f(1) = -4
The first four terms are therefore;
f(2) = f(2 - 1) + 5 = f(1) + 5 = - 4 + 5 = 1
f(3) = f(3 - 1) + 5 = f(2) + 5 = 1 + 5 = 6
f(4) = f(4 - 1) + 5 = f(3) + 5 = 6 + 5 = 11
f(5) = f(5 - 1) + 5 = f(4) + 5 = 11 + 5 = 15
The first four terms are; 1, 6, 11, 15

What is an equation of the line that passes through the point (-5, -3) and is
parallel to the line 3x + 5y = 15?
9514 1404 393
Answer:
3x +5y = -30
Step-by-step explanation:
The parallel line can have the same x- and y-coefficients. You can find the value of the new constant by using the given point for x and y:
3x +5y = 3(-5) +5(-3) = -30
3x +5y = -30
Answer:
I try the top answer and it didn’t work bc it’s y= -3/5x-6

Use properties to rewrite the given equation. Which equations have the same solution as x + + x = – x? Check all that apply.
x + = – x
18x + 20 + 30x = 15 – 6x
18x + 20 + x = 15 – 6x
24x + 30x = –5
12x + 30x = –5
Answer:
options (a), (b), (c), and (e) have the same solution as the solution of 3/5 x + 2/3 + x = 1/2 -1/5x.
Step-by-step explanation:
The given equation is
3/5 x + 2/3 + x = 1/2 -1/5x
First, rearrange the equation to have constant terms and the terms having variable on the separate side.
3/5 x + x +1/5x= 1/2 - 2/3
9/5 x = -1/6
x= -1/6 ÷ 9/5
x= -1/6 x 5/9
x= -5/54 ...(i)
Now, find the solution of all the options in the similar way:
(a) 8/5 x +2/3 = 1/2 -1/5 x
8/5 x + 1/5 x = 1/2 - 2/3
9/5 x = -1/6
x= -1/6 ÷ 9/5
x= -1/6 x 5/9
x= -5/54 which is same as the solution of the mentioned equation. [ from equation (i)]
(b) 18x + 20 + 30x = 15 – 6x
18x+30x+6x = 15 -20
54x=-5
x= -5/54 which is same as the solution of the mentioned equation. [from equation (i)]
(c) 18x + 20 + x = 15 – 6x
18x+x+6x = 15 -20
25x=-5
x= -5/25 which is not the same as the solution of the mentioned equation. [ from equation (i)]
(d) 24x + 30x = –5
54x = -5
54x=-5
x= -5/54 which is same as the solution of the mentioned equation. [ from equation (i)]
(e) 12x + 30x = –5
42x = -5
42x=-5
x= -5/42 which not is same as the solution of the mentioned equation. [ from equation (i)].
Hence, options (a), (b), (c), and (e) have the same solution as the solutions of the given equation.
What is 68% of 118
Show work
Answer:
80.24
Step-by-step explanation:
The easiest way to do this is to convert 68% to a decimal and multiply by 188. To convert a percent into a decimal, all you have to do is move the decimal point twice to the left. So...
68%=.68 Now, we can multiply by 118.
.68x118=80.24 68% of 118 is 80.24!

Answer:
Simplifying
h(23) = 55
Reorder the terms for easier multiplication:
23h = 55
Solving
23h = 55
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Divide each side by '23'.
h = 2.391304348
Simplifying
h = 2.391304348
Step-by-step explanation:
Simplifying
H(4) = k
Reorder the terms for easier multiplication:
4H = k
Solving
4H = k
Solving for variable 'H'.
Move all terms containing H to the left, all other terms to the right.
Divide each side by '4'.
H = 0.25k
Simplifying
H = 0.25k

Madisyn is planting crops in a triangular garden. The triangular garden can be
seen below. What is the amount of fencing that Madisyn needs?
Answer:
The amount of fencing Madisyn needs is approximately 20.77 m
Step-by-step explanation:
The coordinates of the vertices of the triangular garden are;
A(0, 6), B(6, 5), and C(5, -1)
The length of the sides of the triangle can be found through the given coordinates and the distance between coordinates formula presented as follows;
[tex]Distance \ between \ points \ given \ the \ coordinates = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Therefore, the length of AB is [tex]\sqrt{\left (5-6 \right )^{2}+\left (6-0 \right )^{2}} = \sqrt{37}[/tex]
The length of BC is [tex]\sqrt{\left (5-(-1) \right )^{2}+\left (6-5 \right )^{2}} = \sqrt{37}[/tex]
The length of AC is [tex]\sqrt{\left (6-(-1) \right )^{2}+\left (0-5 \right )^{2}} = \sqrt{74}[/tex]
Therefore;
The amount of fencing Madisyn needs = The length of the sides of the triangular garden
The length of the sides of the triangular garden = The length of AB + The length of BC + The length of AC
The length of the sides of the triangular garden = √37 + √37 + √74 ≈ 20.77 m.
The amount of fencing Madisyn needs ≈ 20.77 m.
Select the correct answer. Which statement correctly describes this expression? |x^3|+5 A. the sum of the absolute value of three times a number and 5 B. 5 more than the absolute value of the cube of a number C. the cube of the sum of a number and 5 D. the absolute value of three times a number added to 5
Answer:
B. 5 more than the absolute value of the cube of a number
Step-by-step explanation:
In the above question, we are given this expression: |x^3|+5
| | = This sign means Absolute value,
x^3 = x³ = x × x × x
Hence, the statement that correctly describes the expression |x^3|+5 is :
B. 5 more than the absolute value of the cube of a number
Answer:

The morning temperature in Erin's apartment was 79°. Erin turned up the air conditioner and
the temperature in her apartment that afternoon was 68º. Write an integer to represent the
change in temperature. (1 point)
Enter your answer
Submit
O
BI
Answer:
The integer which represents the change in temperature from morning to afternoon is -11°
Step-by-step explanation:
Since the morning temperature in Erin's apartment was 79°, and the temperature in Erin's apartment that afternoon was 68°. If Erin turned up the temperature and the temperature in the afternoon was 68°. So, the temperature change from 79° down to 68° is thus 68° - 79° = -11°.
So, the integer which represents the change in temperature from morning to afternoon is -11°

How to write a Linear Function??
PLS HELP NOW!
Answer:
i gotchu dude
Step-by-step explanation:
For example, a common equation, y=mx+b y = m x + b , is a linear function because it meets both problems with x and y as variables and m and b as constants.
the steps for writing a linear exp. are
1.) Identify the y-intercept from the graph.
2.)Choose two points to determine the slope.
3.)Substitute the y-intercept and slope into slope-intercept form of a line
.nowww to determine if an equation is a linear function without graphing, you will need to check to see if your function has the characteristics of a linear function. Linear functions are first-degree polynomials. Check that the y, or independent variable, is by itself on one side of the equation.
there are different ways to write linear functions like
1.)f(x) = mx + b (The "slope-intercept" form),
2.)y - yo = m(x - x0) or, equivalently, f(x) = y0 + m(x - x0) (The "point-slope" or "Taylor" form), and.
3.)Ax + By = C (The "general form") which defines y implicitly as a function of x as long as B 0.

David made an error when determining the product of (–2.5)(–8.3). Step 1: (–2.5)(–8.3) = (–8.3)(–2.5) Step 2: = (–8.3)(–2) + (–8.3)(–0.5) Step 3: = (–16.6) + (–4.15) Step 4: = –20.75 In which step did David make his first error? Step 1 Step 2 Step 3 Step 4
Answer:
Step 3.
Step-by-step explanation:
We need to tell the incorrect step in the given problem for the product of (–2.5)(–8.3)
Step 1. (–2.5)(–8.3) = (–8.3)(–2.5)
Step 2:
We can write -2.5 = -(2+0.5)
(–8.3)(-(2+0.5)) = (–8.3)(-2)+(-8.3)(-0.5)
= 16.6 + 4.15
Step 3.
= 20.75
He has done an error in step 3. It should be 16.6 + 4.15 instead of (–16.6) + (–4.15). As a result, he get incorrect answer.

it is step 3

Express your answer as a polynomial in standard form.
f(x) = 3x² + 4x – 7
g(x) = 2x – 11
Find: g(f(x))
Answer:
g(f(x)) = 6x^2 + 8x - 25
Step-by-step explanation:
So, first we have to substitute f(x) into the place of x in the g(x). This will be shown as g(f(x)) (which is what we need to solve). Next, we have to substitute 3x^2 + 4x - 7 into the place of x in 2x - 11. We do this because we had to substitute f(x) into the place of x in g(x).
So this is how your equation should look, and then solve:
g(f(x)) = 2(3x^2 + 4x - 7) - 11
g(f(x)) = 6x^2 + 8x - 14 - 11
g(f(x)) = 6x^2 + 8x - 25 < ---- This is your answer
