The missing x and y values so that each ordered pair will satisfy the given equation y= −2x +1 is computed to bee
How to compute the missing valuesThe equation is a linear function representing a straight line
for ordered pair (3, y)
y = −2x + 1
substitute the value of x
y = -2 * 3 + 1
y = -6 + 1
y = -5
hence the ordered pair is (3, -5)
for ordered pair (x, 1)
y = −2x + 1
2x = 1 - y
x = (1 - y) / 2
substitute the value of y
x = (1 - 1) / 2
x = 0
hence the ordered pair is (0, 1)

0.5 mg / kg
⇒ For 1 kg = 0.5 mg
Relation between mg to ml as per the supplied is given by ,
10 mg / ml
⇒ 1 ml = 10 mg
Now for 40 kg weighs the relation is given by,
1 kg = 0.5 mg
⇒ 40 kg = ( 40 × 0.5) mg
⇒ 40 kg = 20 mg ___(1)
And
1 ml = 10 mg
⇒ ( 2 × 1) ml = ( 2 × 10 ) mg
⇒ 2ml = 20mg ____(2)

The values of x that make the equation true are approximately 5.7 and -0.7 .
The given equation is :
[tex]\frac{x+1}{x} = \frac{2}{x-4}[/tex]
Using cross multiplication this can be written as:
or, ( x + 1 ) ( x - 4 ) = 2 x
or, x² + x - 4x - 4 = 2x
Putting all the like terms together.
or, x² + x - 4x -2x - 4 = 0
or, x² - 5x - 4 = 0
Now we will use the quadratic formula to find the values of x :
[tex]{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}\ \ }[/tex]
or, [tex]{\displaystyle x={\frac {5\pm {\sqrt {(-5)^{2}-4(1)(-4)}}}{2(1)}}\ \ }[/tex]
or, [tex]x = \frac{5+\sqrt{41}}{2} , \frac{5-\sqrt{41}}{2}[/tex]
or, x ≈ 5.7 , -0.7
The roots or zeros of the expression, which are also on the left side of the equation, are used to indicate the values of x that satisfy the equation.
There can only be two possible solutions to a quadratic problem. One argues that if there is only one remedy, there are many different causes of the problem. There are only four possibilities: one real double root, two complex solutions that appear to be complex conjugates of one another, two real solutions, or two real solutions if each of the coefficients has a real value.

y = 1/8x −1
−5x + 4y = −13
A. (0,−1)
B. (8,0)
C. (1,−7/8)
D. (2,−3/4)
The solution to the system of equations y = 1/8x −1 and −5x + 4y = −13 is (2, −3/4). Option D is correct.
We are given:
y = 1/8 x − 1 ..............equation i.
− 5x + 4y = − 13 ..............equation ii.
We will use the substitution method to solve the given equation.
substitute the value of y from equation i in equation ii, and we will get;
− 5x + 4(1/8 x − 1) = − 13
− 5x + 1/2 x − 4 = − 13
(-10 + 1) / 2 x = -13 + 4
-9/2 x = -9
x = -9 * 2 / -9
x = 2
Put the value of x in equation i, we will get;
y = 1/8 *2 − 1
y = 1/4 - 1
y = 1 - 4 / 4
y = -3 / 4
So, the value of x = 2 and the value of y = -3 / 4.
Thus, the solution to the system of equations y = 1/8x −1 and −5x + 4y = −13 is (2, −3/4). Option D is correct.

Given (x – 7)2 = 36, select the values of x. x = 13 x = 1 x = –29 x = 42
Answer:
Unless you wrote the wrong expressions, non of your choice answers are correct!
Step-by-step explanation:
Solve for x:
2 (x - 7) = 36
Divide both sides of (x - 7)×2 = 36 by 2:
(2 (x - 7))/2 = 36/2
2/2 = 1:
x - 7 = 36/2
The gcd of 36 and 2 is 2, so 36/2 = (2×18)/(2×1) = 2/2×18 = 18:
x - 7 = 18
Add 7 to both sides:
x + (7 - 7) = 7 + 18
7 - 7 = 0:
x = 18 + 7
18 + 7 = 25:
Answer: x = 25
The radius of a circle is 33 cm. What is the area of the circle? Give your answer to 1 d.p.
The area of the circle with radius 33 cm is 3419.5 square centimeters.
According to the question,
We have the following information:
Radius of the circle = 33 cm
We know that the following formula is used to find the area of the circle:
Area of the circle = π[tex]r^{2}[/tex] where r is the radius of the circle
There are two approximate values of π which are 22/7 and 3.14. In this case, we will use the value of π as 3.14.
So, we have the following expression:
Area of the circle = 3.14*33*33
Area of the circle = 3419.46 square centimeters
Rounding it off to one decimal point:
3419.5 square centimeters
Hence, the area of the circle with radius 33 cm is 3419.5 square centimeters.

6%, Independent
6%, Dependent
11%, independent
11%, Dependent
The probability that you win is 6%, and the two choices are dependent events option (B) is correct.
What is probability?
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that:
A standard deck of playing cards contains 52 total cards, 13 of which are "spades".
The probability of the first draw:
Probability = favorable outcomes/total outcomes
First draw: 1/4
For the second draw:
Second draw = 12/51
The probability that you win = (1/4)(12/51) = 3/51

Friday: Nabil had $80.50 on a gift card before buying four journals at a bookstore. The bookstore charges 50¢ to use the card. He had $44.00 left on the gift card after buying the journals. If each journal cost the same amount, what was the price of each journal?
Answer:
$9.00 a journal.
Step-by-step explanation:
First off, you can start by subtracting $0.50 from $80.50 because it costs $0.50 to use the card.
You’re left with a new value of $80.00. Since Nabil had $44.00 left over on his card, you can subtract $44.00 from $80.00 to figure out how much he spent.
$80.00
-$44.00
————
$36.00
Since Nabil bought four journals, and they are all equal in cost, you can divide $36.00 by 4 (36/4) and get $9.00.

Answer:
43 cm^2
Step-by-step explanation:
Area of the triangle:
A = (1/2) x base x height
A = (1/2) x (2 cm + 4 cm) x 7 cm
A = (1/2) x (6 cm) x 7 cm
A = (1/2) x 42 cm^2
A = 21 cm^2
The area of the triangle is 21 cm^2
Area of the rectangle:
A = length x width
A = 11 cm x 2 cm
A = 22 cm^2
The area of the rectangle is 22 cm^2
Area of the figure = Area of the triangle + Area of the rectangle
Area of the figure = 21 cm^2 + 22 cm^2
Area of the figure = 43 cm^2
