Verify 18×(7×(-3)=18×7+18×(-3)
Is LHS= RHS ?
[tex]18*(7*(-3))=18*7+18*(-3)\\18*-21=126 - 54\\-378 \neq 72[/tex]
LHS [tex]\neq[/tex] RHS
Answer :
To verify an equation, we need to see if the LHS = RHS.
Equation [tex]\downarrow[/tex]
[tex]18\times(7\times(-3))=18\times7+18\times(-3)[/tex]
Let's solve the left hand side (LHS) first.
[tex]18\times(7\times(-3))\\= 18 \times (-21)\\=\underline{ -378}[/tex]
Now, let's solve the right hand side (RHS).
[tex]18\times7+18\times(-3)\\= 126 - 54\\=\underline {72}[/tex]
But,
[tex]\boxed{-378 \neq 72}[/tex]
We can see that the LHS doesn't match or isn't equal to the RHS.
Hence, we can say that LHS [tex]\neq[/tex] RHS & the equation is NOT true.

What are the coordinates of Point B?
(4, -3)
(-4, 3)
(3, -4)
(-3, 4)
Answer:
( -4 , 3 )
Step-by-step explanation:
Knowing that "y" is the line going up and down and "x' is the line going left to right.
Quadrant | = ( + , + )
Quadrant || = ( - , +)
Quadrant ||| = (- , - )
Quadrant |v = ( + , - )
Refer to image below if needed.
Hence, from the given we can conclude the following:
Quadrant || = ( - , +)
( x , y )
x = -4
y = 3
Thus, we have:
( -4 , 3 )
Therefore, the correct answer is ( -4 , 3 )
Kavinsky
Answer:
B.Step-by-step explanation:
The location on point B is quadrant II.
But what do we not know?
What the coordinates of point B are.So, lets find it in the most simple way:
Start at the origin.From the origin, move 4 spaces to the left on the x-axis.Then, move 3 spaces upward from the y-axis.Now, you are at point B.
In the explanation, the coordinates for x and y are right in my explanation. Read it carefully and find the coordinates:
2nd line: move 4 spaces to the left on the x-axis. This coordinate for that is -4.3rd line: move 3 spaces upward on the y-axis. this coordinate is 3.Now, lets pair that together:
(-4, 3).You have found the coordinates!

When you enter a number in your answer, do not enter any commas in that number. In other words if you want to enter one thousand, then type in 1000 and not 1,000. It's not possible to understand what the interval (1,000,2,000) means, so you should write that as (1000,2000).
The cost in dollars of making x items is given by the function C(x) = 10x + 900. The fixed cost is 900 dollars. C(25 ) = $1150. The Range is 250.
What is a function?The function is a type of relation, or rule, that maps one input to specific single output.
The cost in dollars of making x items is given by the function
C(x) = 10x + 900
a. The fixed cost is determined when zero items are produced. Find the fixed cost for this item.
The fixed cost
C(0) = 10(0) + 900
= 0 + 900
= $900
b. What is the cost of making 25 items?
C(25) = 10(25) + 900
= 250 + 900
= $1150
Therefore, C(25 ) = $1150
c. Suppose the maximum cost allowed is $1900. What are the domain and range of the cost function, C(x)?
The domain is the set of values for which the given function is defined.
Range = Maximum value of the data set - Minimum value of the dataset
Range = C(25 ) - C(0)
= 1150 - 900
= 250

Answer:
87 degrees
Step-by-step explanation:
The triangle with the angles 79 and 15, we can find the last value because all angles in a triangle add up to 180. So, 180-79-15= 86 degrees for the angle of the triangle.
Because the 86 degree angle is complimentary, or when added up to the adjacent angle, is 90 degrees (we see that little box sign), that means that 90-86=4 degrees for the upper triangle in the angle that isn't the question mark. Now that we know 2 values for the top triangle, we can solve for the third value by subtracting those two from 180.
180-89-4=87 degrees. Hope this helps!

what is the answer to the equation below??
4 1/2 ÷ 1/2
Step-by-step explanation:
first of all, remember. when dividing by a fraction, this is the same as multiplying by the upside-down fraction.
and all these signs (including the fraction sign) stand for divisions and really do the same thing and can be exchanged with each other : "/", "÷", ":"
and when writing a number like 4 1/2, it is a shortcut and means actually (4 + 1/2).
so,
4 1/2 ÷ 1/2 = 4 1/2 × 2/1 = 4 1/2 × 2 = (8/2 + 1/2)×2 =
= 9/2 × 2 = 18/2 = 9

Answer: 26.93 square inches
Step-by-step explanation:
first let us find the area of the rectangle shape
rectangle area = length times width
rectangle area = 2 times 11
rectangle area = 22 inches
now let us do the half circle area
half circle area = 1/2(πr^2)
half circle area ~ 1/2 times 3.14(1)^2
half circle area ~ 1/2 times 3.14^2
half circle area ~ 1/2 times 9.8596
half circle area ~ 4.9298
now let’s add the half circle area and the rectangle area to get our total area
total area ~ 4.9298 + 22
total area ~ 26.9298
total area ~ 26.93
26.93 square inches is the total area rounded to the nearest hundredth.
