The ordered pair (4, -5) satisfies the equation
3x- 2y= 22
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
We have ordered pair (4, -5)
First equation, 2x - 5 y= -30
So, 2(4)- 5(-5)= 8 + 25= 33
Second equation,7 x + 4 y = -19
So, 7(4)+4(-5)= 28 -20= 8
Third equation, 6x - y= -29
So, 6(4) +5= 24+ 5 = 29
Fourth equation, 8 x + 3 y= -37
So, 8(4) + 3(-5)= 32 - 15 = 17
Fifth equation, 3x- 2y= 22
3(4)- 2(-5)= 12 + 10 = 22
sixth equation, 2x+ 9y = -37
2(4) + 9(-5)= -37
seventh equation, 5x- 6y= 49
5(4) - 6(-5)= 20 + 30 = 50
eight equation, x+ 8y= -27
4+ 8(-5)= -36

Which value in the set of values below is NOT a solution to the inequality 10- 2y ≥ 4?
Set: {1, 2, 3, 4}
1. 1
2. 2
3. 3
4. 4
Answer:
Option 4: 4 is the correct answer
Step-by-step explanation:
The given inequality is:
10- 2y ≥ 4
In order to check which value is not the solution to the inequality we have to put each value in the inequality. If the inequality is true for the value, it is the solution and it is not true then it is not the solution.
Putting y = 1
[tex]10-2y\geq 4\\10-2(1)\geq 4\\10-2\geq 4\\8\geq 4[/tex]
TRUE
Putting y=2
[tex]10-2y\geq 4\\10-2(2)\geq 4\\10-4\geq 4\\6\geq 4[/tex]
TRUE
Putting y=3
[tex]10-2y\geq 4\\10-2(3)\geq 4\\10-6\geq 4\\4\geq 4[/tex]
TRUE
Putting y=4
[tex]10-2y\geq 4\\10-2(4)\geq 4\\10-8\geq 4\\2\geq 4[/tex]
FALSE
The inequality is not true for y=4.
Hence,
Option 4: 4 is the correct answer

Which of the following statements best describes the end of the decimal conversation of a rational number
Answer:
Any rational number (that is, a fraction in lowest terms) can be written as either a terminating decimal or a repeating decimal . Just divide the numerator by the denominator . If you end up with a remainder of 0 , then you have a terminating decimal.
Step-by-step explanation:
Convert the fraction 7/12
to a decimal.
7/12=0.583¯
This is a repeating decimal.
The bar over the number, in this case 3, indicates the number or block of numbers that repeat unendingly.

Dilations: Triangle RST with vertices R(-5,1), S(-3,4), and T(2,-1): k=2
Answer:R’ (-10,2) S’(-6,8) T’(4,-2)
Step-by-step explanation:
Did it in class
After dilation of ΔRST with the given scale factor we have vertices of ΔR'S'T' as R'(-10, 2), S'(-6, 8) and T'(4, -2).
Given that, ΔRST with vertices R(-5,1), S(-3,4), and T(2,-1).
What is a dilation?Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor. The new figure obtained after dilation is called the image and the original image is called the pre-image.
Given, scale factor is k=2.
So, with using scale factor
R(-5,1)→2(-5, 1)= R'(-10, 2)
S(-3,4)→2(-3,4)=S'(-6, 8)
T(2,-1)→2(2,-1)=T'(4, -2)
Therefore, after dilation of ΔRST with the given scale factor we have vertices of ΔR'S'T' as R'(-10, 2), S'(-6, 8) and T'(4, -2).

5/4 divided by 3/5= what fraction
Answer:
Improper fraction: 25/12
Mix number fraction: 2 1/12
Decimal: 2.083333333...
Step-by-step explanation:
5/4 divided by 3/5 is the same as 5/4 times 5/3
5 times 5/4 times 3
25/12
Answer:
25/12
Step-by-step explanation:
when dividing a fraction, you flip the divisor, so the 3/5 will become 5/3
when you flip the divisor, you flip the sign too, the sign right now is ÷
the opposite of ÷ is ×
so now you have 5/4 × 5/3
multiply the numerators: 5 x 5 = 25
multiply the denominators: 4 x 3 = 12
so now you have 25/12
this fraction cannot be simplified, so 25/12 is your answer

Reduce each ratio to its simplest form.
a. 17 : 102
b. 208⁄52
c. 54 to 2
d. 7 : 49
Answer:
a. 1 : 6
b. 4/1
c. 27 to 1
d. 1 : 7
Step-by-step explanation:
To reduce each ratio to its simplest form, find the greatest common factor(gcf) for both sides of the ratio and divide them by that number.
For example, in part a the greatest common factor is 17. Divide both sides of the ratio by 17:
17/17 = 1 and 102/17 = 6
The ratio becomes 1 : 6.
The gcf for part b is 52. The gcf for part c is 2 and the gcf for part d is 7.
