Since there are complementary angles, the value of angle B is 39°.
Angle A = 7x + 23°
Angle B = 5x + 19°
It should be noted that the total angles in a complementary angle are equal to 90°.
Therefore, we need to add angle A and B together and then equate them to 90°. This will be:
7x + 23° + 5x + 19° = 90°
Collect like terms
12x + 42° = 90°
12x = 90° - 42°
12x = 48°
x = 48°/12
x = 4°
Angle A = 7x + 23° = 7(4) + 23° = 28° + 23° = 51°
Angle B = 5x + 19° = 5(4) + 19° = 20° + 19° = 39°
The value of angle B is 39°.

pounds of coleslaw. How
many more pounds of
macaroni salad does she
have than coleslaw?
Answer:
1.5 pounds more.
Step-by-step explanation:
3.75 - 2.25
= 1.50.
Answer:
1.50 pounds
Step-by-step explanation:
Paula orders a macaroni salad and coleslaw each weighing 3.75 and 2.25 pounds respectively
so, to find how many more pounds of macaroni salad than coleslaw we do,
3.75-2.25=1.50
therefore, macaroni salad has 1.50 pounds more than coleslaw.

Trey is taking his friends out to dinner to celebrate graduation. It will cost him $72 to reserve a table, and another $5 per guest. How many people can he invite if he can only spend up to $130?
Answer:
11 people
Step-by-step explanation:
first, youd subtract the table reservation price from the max price.
130 - 72 = 58
then, since each person costs $5, you find the highest multiple of 5.
in this case, its 55, which has 11 groups of 5 in it.
to make sure:
you can then subtract 55 from 58 to make sure there isnt any extra 5's.
58 - 55 = 3.

Multiply.
[−427⋅(−18)]⋅(−389)⋅(−1)
What is the product?
Answer:
300/1 or 300
Step-by-step explanation:
I took the quiz
The product of the given numbers is 29,89,854.
The given expression is [(−427⋅(−18))⋅((−389)⋅(−1))].
What is product of integers?Integers are the set of whole numbers and their opposites. When you multiply integers, the numbers that you are multiplying are called factors. Your answer after multiplying is called a product.
Product of negative and negative integers is positive.
Now,
(−427⋅(−18)) = 7686
((−389)⋅(−1)) = 389
7686 × 389 = 29,89,854
Therefore, the product of the given numbers is 29,89,854.

What is the equation of the line that passes through the points (4, 15) and (0, 3)?
Answer:
Y=3x+3
Step-by-step explanation:
Gradient = :[tex]\frac{y2-y1}{x2-x1}[/tex] = :[tex]\frac{3-15}{0-4}[/tex] = :[tex]\frac{-12}{-4}[/tex] = 3
Y= mx + c
y = 3x + c
Insert x and y values for first point(4,15)
15 = 3 (4) + c
15 = 12 + c
3 = c
Y=3x +3
Answer:
The equation of the line is y=3x+3
Step-by-step explanation:
y=mx+b is the y intercept form of the equation of this line.
m=slope, and we find the slope by the equation m=y2-y1/x2-x1. Plugging our number into that formula, we get m=3 - 15/ 0 - 4, or -12/-4, which simplifies to 3.
Now we can add our slope into the formula.
y=3x+b
Next, we solve for the y intercept, or b. You can use whatever point to get the answer, but I will use 4 ,15).
y=mx+b is the equation, or substituting the numbers, gets you 15=3×4+b. now solve for b: b=15-(3)(4). b=3.
now, with slope and y intercept plugged in, the final equation is. y=3x+3

How would the domain and range of the function
Y = (1/4)x - 6
be determined? Explain.
Answer:
Domain and range both [tex](-\infty, \infty)[/tex]
Step-by-step explanation:
The range is determined by finding the domain of the inverse of the function(if it has one, in this case it does). The domain is easily determined, because [tex]x[/tex] can obviously range from [tex](-\infty, \infty)[/tex] without restriction.
The inverse of the function can be found as such:
[tex]x=(1/4)f^{-1}(x)-6\\x+6=(1/4)f^{-1}(x)\\4(x+6)=f^{-1}(x)\\f^{-1}(x)=4x+24[/tex].
Here, [tex]x[/tex] can also range from [tex](-\infty, \infty)[/tex] without restriction.
So, the domain and range are both [tex]\boxed{(-\infty, \infty)}[/tex]

Step-by-step explanation:
(-2)² is basically -2 x -2, which we know is 4.
-2² is slightly different. In this case, you don't consider it as the square of -2, but you do the square ignoring the negative sign, and then add it at the end.
So think about it like this,
We do 2² first, and then add the minus, so it becomes -4 instead of positive 4. Does that make sense?
Answer: Incorrect
Step-by-step explanation:
Rule :
[tex](-10)^2=| -10|^2 =100 \\\\ -10^2=-(10)^2=-|10|^2=100[/tex]
Then :
[tex]\rm -2^2=-|2|^2=-4 \\\\ (-2)^2= |-2|^2=4 \\\\ Then : \\\\ -2^2 =(-2)^2 \\\\ -4 \neq 4[/tex]
Rearrange the following equation
