Write the equation of the line through the given point. Use slope-intercept form.
3
(-4,6); perpendicular to y = -
2x+3
Write an equation for the line in slope-intercept form.
(Simplify your answer. Use integers or fractions for any numbers in the equation)
Answer:
2y=x+16
Step-by-step explanation:
condition for a perpendicular line to the previous line is that the gradient M1=-1/M2. looking at the question above the equation of the line given y=-2x+3 that is the first M1=-2. so to get the gradient M2 of the line perpendicular, then M2=-1/-2=1/2. so M2=1/2. so the equation of the new line is y=1/2x+C. so we can find C. since the line passes through (-4,6). when x=-4, y=6, 6=1/2(-4)+C..C=6+2=8. so the equation of the new line y=1/2x+8 we can multiply via 2. so we have 2y=x+16
the equation is 2y=x+16

Sara, Nick and June share some sweets in the ratio 5:5:3. Sara gets 18 more sweets than June. How many sweets does Nick get?
Answer: 45
Step-by-step explanation:
5 : 5 : 3 is simplified so it can be rewritten as 5x : 5x : 3x

What is rectangle?
An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel, opposite sides. Since a rectangle is a two-dimensional form, it has two dimensions: length and width. The rectangle's longer side is its length, while its shorter side is its breadth.
Given:
One side of the canvas is 11.4 inches long,
the shorter side is 8.3 inches,
Calculate the area of the canvas as shown below,
Area of the canvas = Length of the longer side × length of the shorter side,
Area of the canvas = 11.4 × 8.3
Area of the canvas = 94.62 inches².

during the week. Jimmy spent $45 eating out, gain $55 mowing lawns and spent $15 on gas. What was Jimmy’s change in dollars at the end of the week?
Answer:
5
Step-by-step explanation:
Let's look at the question.
Spent- He spent 45 dollars eating out.
He spent an additional 15 dollars on gas
Earned- He earned 55 dollars from mowing lawns
Earned is going to be a positive value.
Spent is going to be a negative value.
The situations don't matter in the context of the question. They are just asking how much he got charged.
The amount charged is always positive. You can never have a negative charged amount of money. That would mean the bank owed you money, which would never happen.
Let's substitute the values into an equation.
The variable C will stand for amount charged.
C = -45 + 55 - 15
Combine the negative values to get -60
Add -60 to 55.
You will get -5, which then you will have to take the absolute value of.
The absolute value will be the charge in dollars at the end of the week.
Jimmy’s change in dollars at the end of the week will be - 5 dollars.
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Jimmy spent $45 eating out, gain $55 mowing lawns and spent $15 on gas.
Now,
Let the total amount Jimmy have = x
Since, Jimmy spent $45 eating out, gain $55 mowing lawns and spent $15 on gas.
Hence, After spent $45 on eating, we get;
The left amount = x - $45
And, After spent $55 on mowing lawns, we get;
The left amount = x - 45 + 55
= x + 10
And, After spent $15 on gas.
The left amount = x + 10 - 15
= x - 5
Thus, At the end of the week, he ended up with 5 dollars less than he started, so the change is -5 dollars.

I NEED HELP ASAP Follow the process for establishing a set of equations: Choose a variable to represent one of the unknowns. Express the remaining unknowns in terms of the variable you chose in step 1. Look for a relationship between the unknowns given in the problem. Write an equation. (Look for the other relationship given in the problem.) The tens digit of a number is twice the ones digit. The sum of the digits in the number is 12. What is the number? Include the entire process for establishing a set of equations, the solution, and an explanation of what the solution means in terms of the variables. Complete your work in the space provided.
Step-by-step explanation:
Identify the variables (x,y) and represent them using the unknowns like this:
Let x represent the tens digit and y represent the ones digit of the number.
Relationships between the unknowns from the question:
x = 2y, and x + y = 12.
We can solve these simultaneous equations by substitution:
x + y = 2y + y = 12, 3y = 12, y = 4. So x = 8.

An electric company calculates a person's monthly bill from the number of
kilowatt-hours (kWh), x, used,
x 200
The function b(ar) = {
0.102,

determines the
bill
How much is the bill for a person who uses 600 kWh in a month?
A. $70
ООО
B, $60
C. $40
D. $80
Answer:
$80Step-by-step explanation:
If a person's monthly bill from the number of kilowatt-hours (kWh), x is modeled by the equation b = 0.15(x - 200) +20, to know the bill for a person who uses 600 kWh in a month, we will substitute x = 600 into the modeled equation as shown;
[tex]b(x) = 0.15(x - 200) +20\\\\b(600) = 0.15(600 - 200) +20\\\\b(600 )= 0.15(400) +20\\\\b(600 )= 15/100*(400) +20\\\\b(600 )= (15*4)+20\\\\b(600 )= 60+20\\\\b(600 )= 80[/tex]
Hence the bill for a person who uses 600 kWh in a month is $80
Question 6 (1 point) If the area of a square is 121 square inches, what is the perimeter of the square? inches
Answer:
44 inches
Step-by-step explanation:
The side length is the square root of the area:
A = s^2
121 in^2 = s^2
√(121 in^2) = s = 11 in
The perimeter of a square is 4 times the side length (since all four sides are the same length).
P = 4s = 4(11 in) = 44 in
The perimeter of the square is 44 inches.
The area of a square is 121 square inches, what is the perimeter of the square? inches
Answer:The perimeter = 44 inches
Explanation:Area = 121 inches²
.°. Length of a side = √(121 inches²) = 11 inches
Now,
Perimeter of the square =
Length of a side×4
= 11 inches × 4
= 44 inches.

[tex]\boxed{\bold{\huge{\boxed{Area\ of\ Trapezium = 150\ cm\²}}}}[/tex]
Step-by-step explanation:
Using Pythagorean Theorem first to find EC
[tex]\sf CB^2 = EB^2+EC^2\\Where \ CB = 13 \ and \ EB = 5 \\13^2 = 5^2 + EC^2 \\169 - 25 = EC^2 \\EC^2 = 144\\Taking \ sqrt \ on \ both \ sides\\EC = 12 \ cm[/tex]
Given that:
AE = EC
AE = 12 cm
Now,
AB = AE + EB
AB = 12 + 5
AB = 17 cm
ABCD is a trapezoid / trapezium
So,
Area of Trapezium = [tex]\sf \frac{AB+DC}{2} (EC)[/tex]
Where AB = 17 , DC = 8 and EC = 12
Area of Trapezium = [tex]\sf \frac{17+8}{2} ( 12)[/tex]
Area of Trapezium = (25)(6)
Area of Trapezium = 150 cm²
