Answer:
y = 7x - 13
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 7x - 8 ← is in slope- intercept form
with slope m = 7
Parallel lines have equal slopes, thus
y = 7x + c ← is the partial equation
To find c substitute (5, 22) into the partial equation
22 = 35 + c ⇒ c = 22 - 35 = - 13
y = 7x - 13 ← equation of parallel line

The Complex Alternative form to the expression (5[cos(π/4) + i sin(π/4)])^3 is given as: (Option C).
What is a complex Alternate form?A complex number of equations will take the form x + yi, where x and y are real numbers and i is an indeterminate that satisfies the rule i² = -1.
Hence, the solution to the above is given as follows:
Step 1 - Ludooph's number pi is given as:
π ≈ 3.14159265
Step 2 - Divide 3.14159265/4
= 0.78539816
Step 3
Cos (0.78539816)
= 0.70710678
It is assumed that the trigonometric angle argument is in radians.
Step 4
Divide: 3.14159265 / 4
= 0.78539816
Step 5 - find the Sin of the result of step 4
sin(0.78539816)
= 0.70710678
It is assumed that the trigonometric angle argument is in radians.
Step 6
Multiply i by the result of Step No 5
= i * 0.70710678
= 0.7071068i
Step 7 - Add the result of step no. 3 and the result of step number 6
= 0.70710678 + 0.7071068i
= 0.7071068+0.7071068i
Step 8 Multiply 5 by the result of step 7
= 5 * (0.7071068+0.7071068i)
= 5 * 0.70710678118655 + 5 * 0.70710678118655i
= 3.53553391+3.53553391i
= 3.53553391 +i(3.53553391)
= 3.5355339+3.5355339i
Step 9 - Exponentiate the results of Step 8 to the third power:
= (3.5355339+3.5355339i) ^ 3
= (5 × ei π/4)3 = 53 × ei 3 × π/4
= 125 × ei 3π/4
= -88.3883476+88.3883476i
If left in the Alternate Complex form, we have:
125[cos(3π/4) + i sin(3π/4)]

Step-by-step explanation:
First I solved for the triangle on the right by adding 58 and 81 then subtracting by 180 and I got 41 degrees for the missing angle. Now for the left triangle you subtract 47 from 180 and you get 133. Answer choice D is the only answer choice that has x and y equal to 133 this is why answer choice D is the correct solution.

True or False
It is possible to have complementary angles where one is acute and one is obtuse.
Explain why or why not.
Answer:
A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. The side opposite the obtuse angle in the triangle is the longest.

Solve the system of equations 2x-y= 13x and -3x+2y=-18 by combining the equations.
Answer:
x = 18/25, y = -198/25
Step-by-step explanation:
Given the system of equations:
2x – y = 13x
-3x + 2y= -18
You can combine these two equations effectively by multiplying the first equation by 2, and adding because -2y and 2y will cancel out when added. So you will be left with only x terms
( 2x - y = 13x ) × 2
+ -3x + 2y = -18
________________
2(2x) - 3x + 2(-y) + 2y = 2(13x) - 18
4x - 3x - 2y + 2y = 26x - 18
x + 0 = 26x - 18
x = 26x - 18
________________
[Then use the properties of equality to simplify the expressions in the equation to derive the value of x]
x - x = 26x - 18 - x (subtraction property of equality)
0 = 25x - 18
0 + 18 = 25x - 18 + 18 (addition property of equality)
18 = 25x
18 / 25 = 25x / 25 (division property of equality)
18 / 25 = x
x = 18 / 25 (symmetric property of equality)
_______________
Now with the value of x, we can find the value of y by substituting the value of x into the variables of the top equation {2x – y = 13x} because this involves the simpliest steps.
Given x = 18 / 25.
2x – y = 13x → 2x – y + y = 13x + y → 2x = 13x + y → 2x – 13x = 13x + y – 13x → -11x = y → y = -11x.
Now that we know y = -11x, y = -11(18/25) which is - (11 × 18) / 25 = -198/25

Find the value of x and the measure of side EF.
Answer:
x=5
EF = 22in.
Step-by-step explanation:
We know EF and DE are equal, so we can solve for x.
5x-3=3x+7
5x-3x=7+3
2x=10
x=5
Now we plug that into EF.
EF = 3x+7 = 3(5)+7 = 15+7=22

6(x + 5) = 6x + 11
5) Intro
Answer:
Equations with one solution: [tex]-2(x-3) = 2x-6[/tex]
Equations with no solution:
[tex]6(x+5) = 6x+11\\5(x-2) = 5x-7[/tex]
Equations with infinite many solutions: [tex]-3(x-4) = -3x+12[/tex]
Step-by-step explanation:
We will solve each equation to see if it has one solution, no solution or infinite many solutions.
An equation where the value of variable can be found has one solution.
An equation with no solution has both sides different.
An equation with infinite solution will have both sides equal after solution(number)
So,
Equation 1:
5(x-2) = 5x-7
[tex]5(x-2) = 5x-7\\5x-10 = 5x-7\\5x-5x = -7+10\\0 = 3[/tex]
As both sides are not equal, equation has no solution.
Equation 2:
[tex]-3(x-4) = -3x+12\\-3x+12 = -3x+12\\-3x+3x = -12+12\\0=0\\[/tex]
As both sides are equal the equation has infinite many solutions.
Equation 3:
[tex]-2(x-3) = 2x-6\\-2x+6 = 2x-6\\-2x-2x = -6-6\\-4x = -12\\\frac{-4x}{-4} = \frac{-12}{-4}\\x = 3[/tex]
As x=3, the equation has only one solution.
Equation 4:
[tex]6(x+5) = 6x+11\\6x+30 = 6x+11\\6x-6x+30 = 11\\30 =11[/tex]
The equation has no solution.
Hence,
Equations with one solution: [tex]-2(x-3) = 2x-6[/tex]
Equations with no solution:
[tex]6(x+5) = 6x+11\\5(x-2) = 5x-7[/tex]
Equations with infinite many solutions: [tex]-3(x-4) = -3x+12[/tex]

Negative StartFraction 9 over 4 EndFraction divided by (negative two-thirds)
Negative StartFraction 9 over 4 EndFraction divided by two-thirds
StartFraction 9 over 4 EndFraction divided by (negative three-halves)
Answer:
ITS B !!!!!!!!!!!!!
Step-by-step explanation:
The equivalent expression is -9/4 ÷ (-2/3).
Option B is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Negative 2 and one-fourth divided by negative two-thirds.
This can be written as,
-2(1/4) ÷ (-2/3)
= -9/4 ÷ (-2/3)
= -9/4 x -3/2
= 27/8 _____(A)
Now,
StartFraction 9 over 4 EndFraction divided by three-halves
This can be written as,
9/4 ÷ 3(1/2)
= 9/4 x 2/7
= 18/28 ______(1)
Negative StartFraction 9 over 4 EndFraction divided by (negative two-thirds)
This can be written as,
-9/4 ÷ (-2/3)
= -9/4 x -3/2
= 27/8 ______(2)
Negative StartFraction 9 over 4 EndFraction divided by two-thirds
This can be written as,
-9/4 ÷ 2/3
= -9/4 x 3/2
= -27/8
StartFraction 9 over 4 EndFraction divided by (negative three-halves)
This can be written as,
9/4 ÷ -3(1/2)
= 9/4 x 2/7
= 18/28
Thus,
From (A) and (2),
-9/4 ÷ (-2/3) is the equivalent expression.

In a sale, a shopkeeper reduced the advertised selling price of a dress by 20%. This resulted in a profit of 4% over the cost price of the dress. What percentage profit would the shopkeeper have made if the dress had then been sold at the original selling price?
HELP my dad will kill me if I don't finish this and I'm stuck on this question
Answer:
30% profit
Step-by-step explanation:
The amount by which the shopkeeper reduced the advertised selling price = 20%
The resulting profit over the cost price = 4%
Let x represent the initial advertised selling price, and let y represent the new selling price, and let c represent the cost price, we have;
x - 20% of x = y
x - x × 20/100 = y
0.8·x = y
y = c + 4% of c = 1.04·c
∴ 0.8·x = 1.04·c
x = 1.04·c/0.8 = 1.3·c
x = 1.3·c = c + 0.3·c = c + 30% of c
x = c + 30% of c
From which we have that the initial advertised selling price, x = The cost price + 30% of the cost price
Therefore, the initial advertised selling price = The cost price + 30%profit on cost price.
The shopkeeper would have made 30% profit if the dress had then been sold at the original selling price.

marco needs to buy some cat food. At the nearest store, 3 bags of cat food cost 13.50. How much would Marco spend on 5 bags of cat food
Answer:
$22.50
Step-by-step explanation:
if 3 bags of cat food = 13.50, divide 13.5 by 3 to get the cost of one bag, which is $4.50.
since hes getting 5, we can use 13.50 once and then the price of one bag (4.5) twice for the other two.
so that would be 13.5 + 4.5 + 4.5 = $22.50
hope this helped :)
Answer:
cost of three bags of cat food = 13.50
cost of 1 cat food = 13.50/3 = 4.50
