The slope of a line is -1/5, and the y-intercept is 5. What is the equation of the line written in general form?
x - 5y - 5 = 0
x - 5y - 25 = 0
x + 5y - 25 = 0
Answer:
x + 5y - 25 = 0
Step-by-step explanation:
Equation of line in slope intercept form is given as:
[tex]y = mx + b \\ \\ plug \: m = - \frac{1}{5} \: \: and \: \: b = 5 \\ \\ y = - \frac{1}{5} x + 5 \\ \\ 5y = - x + 25 \\ \\ x + 5y - 25 = 0[/tex]
Answer:
x + 5y - 25 = 0

Cisco is building a container for his plants. It is made out of a cube and two cylinders. He plans to paint each surface but cuts off the top of the two cylinders. He also wants to reinforce all the edges before putting it together. Which one is greater, the number of surfaces he has to paint, or the number of edges he has to reinforce
Answer:
Neither
Step-by-step explanation:
In the context, Cisco is building container for the plant which is made up of one cube and two numbers of cylinders. He wants to paint each of the surfaces of the figure but he cuts off the top of two cylinders. Thus neither of the surfaces are greater as Cisco has two cylinders or surfaces and a cube or a point that he cuts the two cylinders and now that he has four surfaces and a cube that has four points.

Step-by-step explanation:
Given is an isosceles triangle.
In an isosceles triangle, measure of the sides opposite to the equal angles are equal.
Therefore,
3x + 2 = x + 6
3x - x = 6 - 2
2x = 4
x = 4/2
x = 2 in
x + 6 = 2 + 6 = 8
Perimeter of the triangle
= 8 + 8 + 12
= 28 in

36 - 7p = -7 ( p - 5)
a) No Solution
b) One Solution
c) Infinite Solutions
Answer:
a) No Solution
Step-by-step explanation:
36 - 7p = -7(p - 5)
36 - 7p = -7p + 35
1 - 7p = -7p
1 = 0p
so a) No Solution
Answer:
[tex]36 - 7p = - 7(p - 5) \\ 36 - 7p = - 7p - 7 \times - 5 \\36 - 7p = - 7p + 35 \\ p \: terms \: togather \\ - 7p + 7p = 35 - 36 \\ 0p = - 1 \\ here \: we \: \: have \: 0p \\ so \: no \: solution \\ option(a) \\ thank \: you[/tex]

Sandra wrote the sequence shown:
7, 14, 25, 40, 59
Complete each of the 2 activities for this Task.
Activity 1 of 2
What explicit expression can be used to find the nth term of this sequence?
Answer:
2n^2 + n + 4.
Step-by-step explanation:
7, 14, 25, 40, 59
The differences are 7, 11, 15, 19 which is arithmetic sequence so the given sequence is quadratic.
Compile a table:
n 1 2 3 4 5
term 7 14 25 40 59
Diff: 7 11 15 19
Diff: 4 4 4 - this indicates that first part is 2n^2.
2n^2 2 8 18 32 50
term-2n^2 5 6 7 8 9
- the nth term for the last sequence is 5+ (n - 1)d =
= 5 + (n - 1)* 1
= n + 4.
So nth term for the original sequence is 2n^2 + n + 4.
14/17 as a decimal to the nearest tenth
Answer:
.8
Step-by-step explanation:
14/17 as a decimal is 0.82352941176
we only need to know what its the hundredths and tenths place so we then just round to thenearest tenth so 2 is less than 5 so 8 stays the same therefor out answer is .8
A student tries to solve the equation 2(x-7)+x-9. The student work is shown to the right describe the errors. Then solve the equation correctly
Answer: 3x - 23
Step-by-step explanation:
To solve the equation goes thus:
= 2(x-7)+x-9.
We have to open the bracket first
= 2x - 14 + x - 9
We then collect like terms
= 2x + x - 14 - 9
= 3x - 23
Therefore, the answer is 3x - 23
What is the value of 6x+7y−5 when x = 2 and y = 3?
Answer:
28
Step-by-step explanation:
6(2) + 7(3) - 5
12 + 21 -5
It's a good idea to get into the habit of using parenthses
when substituting numbers in for variables.
Since x = 2 and y = 3, 6x + 7y - 5 is 6(2) + 7(3) - 5.
Simplifying from here, we get 12 + 21 - 5 or 33 - 5 which is 28.

Simplify the following expression completely
(5x4+5x3-17x2+6x)-(3x4+6x3-7x2-12)/x+2
Please show your work
Answer:
6x^2+3x-4/x
Step-by-step explanation:
first multiply to get (20+5x3-17x2+6x)-3x4+6x3-7x2-12/x+2
then remove the two opposites that add up to zero to get (20+15-34+6x)-6x3-7x2/x+2
then remove unnecessarry parentheses to get 1+6x-18-14/x+2 and then calculate to get 3+6x-4/x
then write all of the numerators above the common denominator to get 3x+6x^2-4/x and reorder the terms to get your solution which is 6x^2+3x-4/x

-0.1 = -10c who can answer this
Answer:
c = 0.01 | Hope I helped :')
Steps to answer:
1. Divide both sides by -10.
-0.1/-10=c
2. Simplify -0.1/-10 to 0.01.
0.01=c
3 Switch sides.
c=0.01
---------------
Checking your answer:
−0.1=−10c
1 Let c=0.01.
−0.1=−10×0.01
2 Simplify 10×0.01 to 0.1.
-0.1=-0.1

the value of y is proportional to x when x=3 then y=15 which equation represents the relationship between x and y?
Answer:
explaination
Step-by-step explanation:
# carry on learning
The solution is, A. y = 5x, the equation represents the relationship between x and y.
What is equation?An equation can be stated as a mathematical statement that is made up of two expressions connected by an equal sign. In its normal form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
Direct proportion equation:
y = kx, where k is the coefficient of proportionality
We have:
x = 3 and y = 15
Using the equation to find the value of k:
15 = 3k
k = 15/3
k = 5
The equation of the line:
y = 5x
Correct choice is A
Hence, The solution is, A. y = 5x, the equation represents the relationship between x and y.
