Find x and y. Give reasons to justify your solution.
AB, CD , and EF are straight lines.
Answers
Answer:
x = 15.6°, y = 14°Step-by-step explanation:
From the picture we can see that:
∠COE and ∠DOF are vertical angles as formed by intersection of lines CD and EF, so these angles are equalMO⊥AB as ∠MOB = 90°, therefore ∠AOM = 90°Considering the above we get below to find x:
12° + 2x + 3x = 90°5x = 90° - 12°5x = 78°x = 78°/5x = 15.6°And using this to find y:
48° + 3y = 90°3y = 90 - 483y = 42°y = 42°/3y = 14°Related Questions

the input (x) values of the relation
a set of points that pair input values with output values
x and y values written in the form (x, y)
Answers
Answer:
a set of points that pair input values with output values
Step-by-step explanation:
The set of points that relate, input values with output values.
A relation is a set of points that pair input values with output values.
Therefore the correct option is C.
In mathematics, a relation is a set of ordered pairs, where each pair consists of an input value (x) and an output value (y) that are related to each other in some way.
These ordered pairs represent the relationship between the input and output values of the relation.
So, a relation can be represented as a set of points in the coordinate plane, where each point represents an ordered pair (x, y). The relation itself is not specifically the input (x) values or the output (y) values, but rather the collection of all the paired values.
Therefore the correct option is C.

Answers
Answer:
(3x−y)(x+7y)
Step-by-step explanation:
Factor (2x+3y)^2−(x−4y)^2
3x^2+20xy−7y^2
=(3x−y)(x+7y)
Answer:
(3x - y)(x + 7y)
Step-by-step explanation:
Given
(2x + 3y)² - (x - 4y)² ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b)
Here a = 2x + 3y and b = x - 4y , then
(2x + 3y + x - 4y)(2x + 3y - (x - 4y))
= (3x - y)(2x + 3y - x + 4y) = (3x - y)(x + 7y)
Thus
(2x + 3y)² - (x - 4y)² = (3x - y)(x + 7y) ← in factored form
Henry makes $12.50 per hour for the first 40 hours he works in a week. For 5 points
each additional hour he makes $18 per hour. How much did he make if he
worked 44 1/2 hours last week? *
Answers
Answer:
He made $581 if he worked 44 1/2 hours last week
Step-by-step explanation:
Let us solve the question
∵ Henry makes $12.50 per hour for the first 40 hours
∵ For each additional hour, he makes $18 per hour
→ We need to find how much he made if he worked 44 1/2 hours
→ At first, find his earning for the first 40 hours
∵ His earning in the first 40 hours = 40 × 12.50
∴ His earning in the first 40 hours = $500
→ Find how many hours he worked after the first 40 hours
∵ 44 1/2 - 40 = 4 1/2 hours
∴ He worked 4 1/2 hours over the first 40 hours
→ Find his earning from them
∵ His earning in 4 1/2 hours = 4 1/2 × 18
∴ His earning in 4 1/2 hours = $81
→ Now add the two amounts to find his total earning
∵ His total earning = 500 + 81
∴ His total earning = $581
∴ He made $581 if he worked 44 1/2 hours last week

Write the standard form of the equation y-3=-2/3(x+5)
Answers
Answer:
In linear standard form, 10x-15y=29
Step-by-step explanation:
The solution is y = ( -2/3 )x - 1/3
The standard form of the equation y-3=-2/3(x+5) is given by the equation A
where y = ( -2/3 )x - 1/3
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
So , the standard form of the equation of line is given by equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
Now ,
y - 3 = -2 / 3 ( x + 5 )
Multiply by 3 on both sides of the equation , we get
3y - 9 = -2 ( x + 5 )
On simplifying the equation , we get
3y - 9 = -2x - 10
Adding 9 on both sides of the equation , we get
3y = -2x - 1
Divide by 3 on both sides of the equation , we get
y = ( -2/3 )x - 1/3
The equation of line is y = ( -2/3 )x - 1/3 where the slope of the line is -2/3 and the y intercept of line is -1/3
Hence , The standard form of the equation y-3=-2/3(x+5) is given by the equation A where y = ( -2/3 )x - 1/3

solve for x if z = m - x
Answers
Answer:
x=m-z
Step-by-step explanation:
The first step is to isolate x and to do this we got to subtract m from both sides which would give us -m+z=-x, the next step is to get x to be positive so we have to divide both sides by negative 1 which is because there is a 1 beside all of the values, and when we do divide both sides by negative 1 we get x=m-z

-2 x -4 = 8
8 x 9 = 72
Hope this helps! Please mark Brainliest!
Answer:
72 = Positive
Step-by-step explanation:
The property we use,
→ Associative property
Now the product will be,
→ (-2 × -4) × 9
→ 8 × 9 = 72
→ -2 × (-4 × 9)
→ -2 × (-36) = 72
Then the required sign is,
→ Positive (+ve)
Hence, the product is 72.
What is an equation in point slope form of the line that passes through (7, 1) and (-3,9)
Answers
Answer:
y= -4/5x+33/5
Step-by-step explanation:
for questions like these, the slope is always defined as the change in y over the change in x or use the equation m=y2-y1/x2-x1.
x1=7 and y1=1
x2=-3 and y2=9
now plug these numbers in to the equation. m= 9-1 / -3-7 Or m= 8/-10 simplified to m= -4/5
now that we have the slope you can plug it in to the equation y=mx+b and get y= -4/5 + b.
to find b, the y-intercept, you can use either of the two points and the answer will be the same. for this one, I'll use (7,1).
1= -4/5 x 7+b. b= 33/5

Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Jacinda = 16 baskets
Greta = 4 baskets
The number of baskets Jacinda made is how many times more than the number of baskets Greta made?
To obtain this :
Number of baskets Jacinda made / Number of baskets Greta made
If Jacinda's basket = J ; Greta's basket = G
J / G
16 / 4 = 4
Hence, Number of basket Jacinda made is 4 times more than that made by Greta
a common mistake people make when working with exponents is to multiply the base by the exponent instead of raising the base to the power of the exponent. For instance, they would mistakenly say that 2^3 is 6 (because 2x3=6) when the correct answer is actually 8 (2x2x2=8) are there any pairs of numbers for which this mistake in thinking actually gives the correct answer? In other words are there any solutions to the equation a^x=a X what are the?
