Answer:
37
Step-by-step explanation:
Use PEMDAS, in this case, start with multiplication: (2)(-7), don't forget there is a minus sign in front of the two which is important later, then move on to dividing (-9) by (-3). Then you are left with 20-(-14)+3, which is the same as 20+14+3, which equals 37.
The set of ordered pairs shown below is a relation that is
a function of x.
{(-5, 1), (-4, 1), (−3, 1), (−2, 1)}
Which ordered pairs could be included in the set so that
the relation remains a function of x?
O (-3,0), (-1, 1)
O (-6, 1), (-5, 1)
O (-6, 1), (-1, 1)
O (-2, 2), (-1, 1)
The ordered pairs that could be included in the set so that the relation remains a function of x is (-6, 1), (-1, 1).
What is defined as the relation of function?A function is a relation that states that there must be only one output for each input (or) we can say that a function is a special type of relation (a set of ordered pairs) that follows a rule, i.e., every X-value should be related with only one y-value.The Cartesian product is a subset of it. Alternatively, a slew of points (ordered pairs). In other words, the relationship between the two sets is described as a collection of a ordered pair, where the ordered pair is formed by an object from each set.For the given relation that is a function of x.
{(-5, 1), (-4, 1), (−3, 1), (−2, 1)}
As, from the definition of the function, the domain of the function will not repeat in the set.
Thus, (-6, 1), (-1, 1) is the ordered pairs that could be included in the set so that the relation remains a function of x.

find X and Y so that the quadrilateral is a parallelogram 5 y 55 ,11x
A few properties of a parallelogram.
1) Opposite sides are always equal.
2) Opposite angles are always equal.
3) The sum of all the angles is 360.
In part 2, we are given the angles. Therefore, we can apply the 2nd property.
11x = 55
5y = z (lets say the unknown is z).
Now, 11x = 55
x = 55/11
x = 5
Now, we have to angles of 55 degrees but we don't know about y and z. Therefore, we have to apply the third property.
55 + 55 + 5y + z = 360
110 + 5y + z = 360
5y + z = 360 -110
5y + z = 250. (i)
According to property 2, 5y = z. Hence, put the value of 5y in the equation (i), we get
5y + z = 250
z + z = 250
2z = 250
z = 250/2
z = 125
From the value of z, we can find the value of y using z = 5y
125 = 5y
5y = 125
y = 125/5
y = 25
Hence, x = 5 and y = 25

Think the length of a rectangle is 5 inches longer than its width if the perimeter of the rectangle is 42 inches find it’s area
The area of the rectangle is 104 inches²
Define Area of Rectangle
The area of a rectangle is the space occupied by the rectangle inside its perimeter.
Given that, the perimeter is 42 inches
we know, the formula of perimeter of rectangle = 2(L + W)
so, the first equation will be
2(L + W) = 42
or, 2L + 2W = 42 ----------eq(i)
Next, the length of a rectangle is 5 inches longer than its width, so
L = W + 5
or, L - 5 = W --------------eq(ii)
Now, the eq(i) is
2L + 2W = 42
Put W value from eq(ii),
2L + 2(L- 5) = 42
=> 2L + 2L - 10 = 42
=> 4L - 10 = 42
=> 4L = 52
=> L = 13
We got, L = 13 put this value in any of the equation
I'm putting the value in eq(ii) as it easy for to solve
=> 13 - 5 = W
=> W = 8
If you want to cross verify the values of L and W , then simply put the values in both the equation and LHS = RHS like that
2(13) + 2(8) = 42 (correct)
13 - 5 = 8 (correct)
Now, we got length and width so now just put the values of L and W in area of rectangle formula,
Area of rectangle = Length * width
= 13 * 8
Area of rectangle = 104 inches²
Hence, The area of the rectangle is 104 inches²

c. Which car could travel the greater distance
on 1 gallon of gas?
Thank you!
Answer:
a) gas mileage of blue car: 23.667 miles/gallonb) gas mileage of silver car: 34 miles/gallonc) The silver car would travel a greater distance on 1 gallon than the blue car.Step-by-step explanation:
a) gas mileage of blue car:gas mileage = miles covered/gallons used
but:
miles covered = [tex]35\frac{1}{2}[/tex]
= 35.5
gallons used = 1[tex]\frac{1}{2}[/tex]
= 1.5
gas mileage = 35.5/1.5
gas mileage = 23.667 miles/gallon (to 3 decimal places)
b) gas mileage of silver car:gas mileage = miles covered/gallons used
but:
miles covered = [tex]27\frac{1}{5}[/tex]
= 27.2
gallons used = [tex]\frac{4}{5}[/tex]
= 0.8
gas mileage = 27.2/0.8
gas mileage = 34 miles/gallon
c)
gas mileage of blue: 23.667 miles/gallon implies the blue car will travel 23.667 miles on 1 gallon
gas mileage of silver: 34 miles/gallon implies the silver car will travel 34 miles on 1 gallon
Hence the silver car would travel a greater distance on 1 gallon than the blue car.

What is density curve ?
A density curve is a curve that illustrates the general shape of a data distribution. It is always above the x-axis; the area beneath it is always equal to one whole; the area beneath shows the percentage of all observations that fall in a given range. It is statistically easier to deal with a smooth curve than a histogram.
The bell-shaped density curve, which symbolizes the normal distribution, is the most well-known.

How to find percentage?From the Latin word "per centum," which meaning "by the hundred," the word "percentage" was borrowed. The denominator of percent's is 100, making them fractions. In other words, it is the relationship between a component and a whole in which the value of the entire is consistently set to 100. The value of the entire is always 100 in a percentage, which is a ratio or fraction. Sam, for instance, would have received a score of 30 out of 100 on his arithmetic test if he received a 30%. When expressed as a ratio, it is written as 030:10 and as a fraction, 30/100. An quantity or part that is contained in each hundred is known as a percentage. The symbol "%" signifies that it is a fraction with 100 as the denominator.
Sales price = $48.90
Amount needed to be paid = 8.5% of $48.90 + $48.90
= 4.15 + $48.90

Answer:
(g ∘ f)(6) = 216
Step-by-step explanation:
Pre-SolvingWe are given the functions f(x) = 2x - 6 and g(x)=x³
We want to find the value of (g∘f)(6), where we first find the value of f(6), and then substitute that value into g(x).
SolvingSubstitute 6 as x in f(x)=2x-6.
f(6)=2(6)-6
Multiply
f(6)=12-6
Subtract
f(6)=6
Now substitute 6, which is the value of f(6) as x in g(x) = x³.
g(6)=6³ = 6 * 6 * 6 = 36 * 6 = 216
The value of g(6) is the same as the value of (g ∘ f)(6), as the 6 that we plugged into g(x) is the value of f(6).
Therefore, (g ∘ f)(6) = 216.

What is an algebraic expression?An algebraic expression is described as a mathematical expression that is composed of terms, factors, coefficients, constants and variables.
They are described as expressions made up of arithmetic operations which includes;
ParenthesesSubtractionAdditionMultiplicationDivisionBracket, etcGiven the expression;
46. |2x + 5| = 3x
Take the absolute value, we have;
2x + 5 = 3x
collect like terms
2x - 3x = - 5
-x = -5
x = 5
48. (3h + 8) + 2 = 13
expand the bracket
3h + 8 + 2 = 13
collect like terms
3h = 13 - 10
3h = 3
Make 'x' the subject of formula
h = 1
50. Seven is at most the quotient of a number d and -5.
This is expressed as;
7 ≤ d/ -5
Hence, the values are x = 5, h = 1 and 7 ≤ d/ -5
