The equation of the straight line is 2y - x +3 = 0 .
A straight line's general equation is y = mx + c, wherein m denotes the line's slope and c its y-intercept.
It is the geometry-related straight line equation that is employed the most frequently. A straight line's equation can be expressed in a variety of ways, including point-slope form, slope-intercept form, generic form, standard form, etc. A solid line is a two-dimensional geometric object that can be stretched to infinity on both ends.Let us calculate the slope of the line:
slope = (2-6)/(7-(-1))
m= 1/2
Equation of the line =
y - 2 = 1/2 (x-7)
or, 2y -4 = x - 7
or, 2y - x +3 = 0
Therefore the equation of the line is 2y - x +3 = 0.

What do you mean by interest?
In the fields of finance and economics, interest is the payment of a sum over and above the principle amount to a lender or depositor by a borrower or deposit-taking financial institution at a set rate. Interest is not the same as a charge that the borrower could pay to the lender or another entity. Additionally, it differs from a dividend, which is a payment made to shareholders from a company's profit or reserve, but not at a set rate predetermined in advance, but rather on a pro rata basis as a portion of the rewards received by risk-taking business owners when revenue earned exceeds all costs. In contrast to profit, which is obtained by the owner of an asset, investment, or business, interest is paid to the lender.
Interest earned by Kylie = (55x7)/(100x12) x 681
= 218.48

F(x)=7x-4 and f(x)=17 find x
Answers
Answer:
x = 3
Step-by-step explanation:
We are given an equation in function notation and asked to solve for x. We can do this by isolating the variable.
Solving for x
First, substitute 17 into the equation for f(x).
17 = 7x - 4Now, we can isolate the x-variable by adding 4 to both sides.
21 = 7xThen, divide both sides by 7.
3 = xThis means when f(x) = 17, x = 3.
Checking the Answer
Now that we have solved for x, we can check the answer we got. Plug 3 into the original equation for x and see if the equation remains true.
17 = 7(3) - 417 = 17Since 17 = 17 is a true statement, the answer x = 3 must be correct.
Use the drop-down menus to complete each equation so the statement about its solution is true.
Answers
You have not provided the contents of any of the drop-down menus, so we cannot say for certain what the answers should be--except in the case of "infinitely many solutions.
For no solution,2x + 9 + 3x + x = 6x
For one solution,2x + 9 + 3x + x = 15
For infinitely many solutions,2x + 9 + 3x + x = 6x + 9
Based on the given conditions,
(1) No solutions :
There will be no solutions when the left side is inconsistent with the right side:
2x + 9 + 3x + x = _ x + _
We can sum of difference,
6x + 9 = 6x
Subtract 6x from both sides,
6x - 6x = -9
9 = 0
9 = 0 which is absurd and hence the equation has no solution.
(2) One solutions :
There will be one solution when the left side and right side are not inconsistent and not the same.
2x + 9 + 3x + x = 15
6x + 9 = 15
Subtract 9 from both sides.
6x = 6
Divide both sides by 6.
x = 1 and this is the only solution.
(3) Infinity solutions :
There will be an infinite number of solutions when the equation is true for any value of x. This will be the case when the left side and right side are identical.
2x + 9 + 3x + x = 6x + 9
6x + 9 = 6x + 9
Subtract 6x from both sides,
9 = 9, both sides are balanced which means, the equation has infinitely many solutions.
Therefore,
For no solution,2x + 9 + 3x + x = 6x
For one solution,2x + 9 + 3x + x = 15
For infinitely many solutions,2x + 9 + 3x + x = 6x + 9

Using the surface area of a rectangular prism, we can conclude that the maximum width Jaxon can build the table is (D) w = 3.5 ft.
What is a rectangular prism?The term "cuboid" can also refer to a rectangular prism. Although it looks like a cube, it is not one. All of its characteristics are the same as a cube's, with the exception that its faces are rectangles as opposed to a cube's square faces. A cuboid is a six-sided solid known as a hexahedron in geometry. Quadrilaterals make up its faces. Cuboid means "like a cube," in the sense that a cuboid can be converted into a cube by varying the length of its edges or the angles between its faces.So, the maximum width can be:
To solve this, we need to take all options in confirmation and do a hit-and-trial method to find the perfect length of the width.The formula for the surface area of a rectangular prism: A=2(wl+hl+hw)Where, h = 2 feet and l = 4 feet.
(A) When, width = 8.3 feet
A = 2(wl+hl+hw)=2·(8.3·4+2·4+2·8.3) = 115.6115.6 × $0.50 = $57.8Hence, this option is not correct.
(B) When, width = 1.1 feet
A = 2(wl+hl+hw)=2·(1.1·4+2·4+2·1.1) = 29.229.2 × $0.50 = $14.6Hence, we need to check more options as it is within the budget of $29.
(C) When, width = 7.2 feet
A = 2(wl+hl+hw)=2·(7.2·4+2·4+2·7.2) = 102.4102.4 × $0.50 = $51.2Hence, this option is not correct.
(D) When, width = 3.5 feet
A = 2(wl+hl+hw)=2·(3.5·4+2·4+2·3.5) = 5858 × $0.50 = $29Hence, this is the perfect option.

What are the costs?The first step is to form a system of equation using the information that is provided in the question:
100a + [(200 - 100)b] = 7
100a + 100b = 7 equation 1
100a + [(310 - 100)b] = 9.20
100a + 210b = 9.2 equation 2
Where:
a = cost of each of the first hundred copiesb = cost of the additional copiesThe two equations formed above would be solved using the elimination method.
Subtract equation 1 from equation 2
110b = 2.2
Divide both sides of the equation by 110: b = 2.2 / 110
b = 0.02
Substitute for b in equation 1:
100a + 100(0.02) = 7
100a + 2 = 7
Combine similar terms: 100a = 7 - 2
Add similar terms: 100a = 5

After 7.5 years will the balance of the account be $15,478.
Given:
fabiana opened a savings account with $14,200 that earns 1.2% simple interest annually.
here A = 15478 , p = 14,200 , r = 1.2%
Simple interest formula:
A = p(1 + rt)
15478 = 14,200(1 + 1.2%t)
15478 = 14,200 + 14,200(0.012t)
1278 = 170.4t
t = 1278/170.4
t = 7.5 years
Therefore after 7.5 years will the balance of the account be $15,478.

8 = 8 (v - 5) is the solution 6 or -10 or -1 or 2 or is none of them the solution
Answers
Answer:
solution is v=6
Step-by-step explanation:
8=8(v-5)
1. expand the brackets
8=8v-40
2. get the v on one side so we +40 on each side
48=8v
3. divide each side by 8 as we want the value of v not 8v
6=v
4. Therefore your final answer is v=6 (solution is 6)
can someone help me please?
Answers
The values of the variables are :
10. x = 8 and y = 9
11. x = 20 /9 and y = - 7/ 9
12. x = 3.08 and y = 4x = 12.32
10 . Given equations are ; 7x -5y = 11 ------- equation 1
and y = x + 1
On substituting this value in equation 1
we get 7x - 5 ( x + 1) = 11
7x - 5x - 5 = 11
2x = 16
x = 8 and thus y = 8 + 1 = 9
11. Given equations are : 5x - 4y = 22
x = y+ 3
On again substituting the values we get
5y + 15 - 14 y = 22
- 9 y = 7
y = - 7/ 9 and x = 20 / 9
12. Given equations are 3x + 8y = 108
and y = 4x
On again substituting equations we will get
3x + 32x = 108
35 x = 108
x = 108 / 35
x = 3.08 and y = 4x = 12.32
