how do I put 8x=26+14y in standard form
The standard form of the equation of the given straight line is 4x + (-7)y = 13.
We are given an equation. The equation is linear in nature. The equation represents a straight line. The equation is given below.
8x = 26 + 14y
We need to convert this equation to standard form. The standard form of an equation for a straight line is given below.
Ax + By = C
We need to rearrange the given equation so that it matches the correct format. The equation is written below.
8x - 14y = 26
We can simplify the equation further by dividing the whole equation by two.
4x + (-7)y = 13
Hence, the standard form of the equation is 4x + (-7)y = 13.

the cost of using a parcel service is r dollars for the first 3 pounds and s dollars for each additional pound. which of the following expressions represents the cost, in dollars, of sending a parcel that weighs 9 pounds?
a) r+3s
b) r+6s
c) 3r+6s
d) 3r+9s
e) 9r+9s
Answer:
The correct answer is: c) 3r + 6s
Step-by-step explanation:
the first 3 pounds are always going to be r dollars, then every additional pound will be s dollars.
Since we have a package that weighs 9 pounds; 3 pounds will cost r dollars and 6 pounds wills cost s dollars.
example:
lets say that r = 10 and s = 5
the first 3 pounds will cost 10 dollars and then every pound after would be 5 dollars
so:
3(10) + 6(5)
This is just an example, since we don't know the actual values of r and s, we just use those variables.
find the quadratic function
For the quadratic function y = ax² + bx + c , for which graph passes through the points (2, 31), (3 , 45) , (1, 19) is given by y = x² + 9x + 9.
As given in the question,
Standard form of quadratic function,
y = ax² + bx + c
Graph of the quadratic function passes through the points (2, 31),
(3 , 45) , (1, 19) .
When passes through (2, 31)
31 = 4a + 2b + c __(1)
Passes through (3,45)
45 = 9a + 3b + c __(2)
Passes through (1, 19)
19 = a + b + c __(3)
Multiply 9 to (3) and subtract (2) from it,
9a + 9b + 9c =171
9a +3b + c = 45
6b + 8c = 126 ____(4)
Now, Multiply 4 to (3) and subtract (1) from it,
4a + 4b + 4c =76
4a +2b + c = 31
2b + 3c = 45____(5)
Multiply 3 to (5) and subtract (4) from it,
6b + 9c = 135
6b + 8c =126
c = 9
Substitute c= 9 in (5) we get,
2b + 3(9) = 45
⇒ b = 9
Now , substitute b = 9, c = 9 in (3) we get,
a + 9 + 9 = 19
⇒ a = 1
Required quadratic function is :
y = x² + 9x + 9
Therefore, for the quadratic function y = ax² + bx + c , for which graph passes through the points (2, 31), (3 , 45) ,(1, 19) is given by y =x² + 9x + 9.

Answer:
23) $248,943.75
24) $384
Step-by-step explanation:
23) 266,250/100= 2662.5 which is 1%
2662.5×6.5=17,306.25 which is 6.5%
Since it is a mark up we subtract 17,306.25 from 266,250 to find the
original price.
24) 320÷10=32 which is 10%
32×2= 64 which is 20%
Since it is a discount we add 64 to 320 to find the original price.

How to interpret graph of a parabolaThe graph of a parabola is represented by a curve as used in the graphs attached in the equation
Parabolic graphs are also called graph of quadratic equation
The equation is usually in this form
y = ax^2 + bx + c
when it is "y =" it is a vertical parabola the graph will either opens up or down
The coefficient of "x^2" which is "a" says if the curve opens upwards or downwards. when a is:
positive the parabola opens upwards andnegative means the parabola opens downwardsy > x^2 - 1 "a" is positive hence opens upwards
y ≤ -x^2 + 4 "a" is negative hence opens downwards

Use the two yellow points to write the equation in slope-intercept form. Write any coefficients
as integers, proper fractions, or improper fractions in simplest form.
PLS RN!!
The equation in slope intercept form is y = -4x + 24.
From the graph:
yellow points are (6,0) and (4,8).
slope intercept form is y = mx + c.
slope m = 8 - 0 / 4 - 6
= 8/-2
= -8/2
= -4
Substitute m and (6,0)
y = mx + c
0 = -4*6 + c
c = 24
y = mx + c
y = -4x + 24.
Therefore The equation in slope intercept form is y = -4x + 24.
