Solve the following using substitution method
Answers
Solution :
2a + 2b = 7 ...1)
4a + 3b = 12 ...2)
In equation, 1)
a = (7 - 2b)/2 ...3)
Putting value of a in equation 2) we get :
4 × (7 - 2b)/2 + 3b = 12
2( 7 - 2b ) + 3b = 12
14 - 4b + 3b = 12
b = 2
Putting value of b in 3) we get :
a = ( 7 - 2×2)/2
a = 3/2 = 1.5
Now,
2x - 3y = 16 ...5)
x + 2y = -6 ...6)
x = -6 - 2y
Putting above value of x in eq 5) , we get :
2( -6 - 2y ) - 3y = 16
-12 - 4y - 3y = 16
7y = -28
y = -4
x = -6 - ( 2× -4 )
x = 2
Hence, this is the required solution.
To which rational number to which rational subset(s) does the following number belong?
15
1. Rational Numbers
II. Natural Numbers
III. Whole Numbers
IV. Integers
Answers
Answer:
15 belongs to the set of natural numbers , whole numbers , integers & rational numbers.
Step-by-step explanation:
TO FIND :-
those subsets to which 15 belongsFACTS TO KNOW BEFORE SOLVING :-
N = Set of all natural numbers
W = Set of all whole numbers
Z = Set of all integers
Q = Set of all rational numbers
It can be said that :-
N ⊂ W (∵ Whole numbers include all natural numbers along with 0)W ⊂ Z (∵ Integers include positive numbers i.e. whole numbers along with negative numbers.)Z ⊂ Q (∵ Rational numbers include all integers along with fractions.)Hence , N ⊂ W ⊂ Z ⊂ Q
SOLUTION :-
Method 1 -
{15} ⊂ N (∵ 15 is an element of set N. {15} a singleton set & it can be called as the subset of N )
⇒ {15} ⊂ N ⊂ W ⊂ Z ⊂ Q
∴ 15 belongs to the set of natural numbers , whole numbers , integers & rational numbers too.
Method 2 -
A rational number is a number which can be expressed in "p/q" form where p,q are integers & q ≠ 0. 15 can also be expressed as [tex]\frac{15}{1}[/tex]. Hence, 15 is a rational number i.e. it belongs to the set of rational numbers.Natural numbers are the countable numbers. 15 is a countable number. So , 15 is a natural number i.e. 15 belongs to the set of natural numbersWhole numbers include all natural numbers as well as zero. 15 is a natural number. So , 15 is also a whole number i.e. 15 belongs to the set of whole numbers.Integers include the negative numbers as well as whole numbers. 15 is a whole number. So , 15 is also an integer i.e. 15 belongs to the set of all integers.Which choices are equivalent to the fraction below? Check all that apply.

Answer:

Step-by-step explanation:
Let's do the smaller parts at the edge.
The formula for a triangle is 1/2bh
The base is 3 the height is 4
3 times 4 is 12
12 divided by 2 is 6
Since there are two of the same triangle on the edge both of the triangle's area is 6 which is 12
No for the upper triangle, the base is 6 and the height is 4
4 times 6 is 24
24 divided by 2 is 12
12 plus 12 is 24
The answer is
The area of the shaded parts of the triangle is 24 in^2

Absolute error = 0.6m
Percentage error = 6%
Step-by-step explanation:
Given that :
Actual height = 10.4 m
Estimated height = 11 m
Tbe percentage error :
The absolute error :
|Actual value - Estimated value|
|10.4 - 11| = 0.6 m
Percentage error :
|Actual value - Estimated value| / actual value * 100%
(0.6 / 10) * 100%
0.06 * 100%

09.03 MC) What is the domain of the following parabola? (5 points) u-shaped graph that opens down with a vertex of 2, 3 Select one: a. x ≥ 2 b. x ≤ −1 c. y ≤ 3 d. All real numbers
Answers
Answer:
The correct option is d: All real numbers.
Step-by-step explanation:
For a function f(x), the domain is the set of all the possible values of x that we can input in that function.
A general way to find the domain of a function is:
First, assume that the domain is the set of all real numbers.
Then, look at restrictions implied:
like in functions like:
f(x) = 4 if x > 3
Here the domain of the function is implied.
Third, let's find values of x that make "problems" with our function (for example, a zero in the denominator) and then remove these points from the domain.
In this case, we have a quadratic function:
y = a*x^2 + b*x + c
Here we do not have any problem (like a zero in a denominator), and we do not have any restrictions (We only know that the parabola is U shaped, so it is a function, and that its vertex is (2, 3) )
Then we can conclude that the domain of this function is the set of all real numbers.
The correct option is d: All real numbers.

Using the slope formula, we can calculate the rate of Marisol's and Timothy's Machines.
[tex]m = \frac{y_1-y_2}{x_1-x_2}[/tex]
Marisol:
[tex]m = \frac{18-12}{3-2} \\m=6[/tex]
Timothy:
[tex]m=\frac{54-36}{6-4} \\m=\frac{18}{2} \\m=9[/tex]
Now that we know the rate of their machines, we need to choose a rate that is between 6 and 9. Therefore, the rate of Zorian's machine needs to be y = 8x.
