4x times4b be fast nowwwwwwwwwwwwwwww pls
Answer:
16xb
Step-by-step explanation:
In algebra the numbers are multiplied with the numbers and the variables are multiplied with the variables.
In this question we would multiply x with b and 4 with 4 .
Multiplying x with b would give xb and 4 with 4 gives 16
So the answer will be 16xb
For example if you have 3x and 10 z the answer would be 30xz

Two cards are dealt at random from a standard deck of 52 cards. What is the probability that the first card is a King and the second card is a $\heartsuit$
Answer:
1 / 51
Step-by-step explanation:
Given that :
Number of cards in a deck = 52
Number of heart suit = 13
Number of kings = 4
Recall:
Probability = (required outcome / Total possible outcomes)
P(first card is king) = 4/52 = 1/13
P(second card is heart) = 13/51
Hence,
P(first card is king) * P(second card is heart)
(1/ 13) * (13/51) = 13 / 663 = 1/ 51
Answer:
1/53
Step-by-step explanation:
So, you have 4 kings in a deck. You have a 4/52 chance in the first one which simplifies to 1/13. There are 13 hearts in a deck. 13/53 * 1/13 = 1/53. Sorry if I got this one wrong.

The correct range for the function ƒ(x) = x − 9 if the domain is (3, -3, 0) is:
Answer:
The correct range is thus;
(-6,-12,-9)
Step-by-step explanation:
Here, we want to get the range given the domain
we simply make a substitution of the domain in the equation so as to get the range
So let us substitute the value of the domain one after the other
f(3) is 3-9 = -6
f(-3) = -3-9 = -12
f(0) = 0-9 = -9

What is the solution to the system below?
-4x + 5y = 27
x - 6y = -2
Step-by-step explanation:
I used substitution method
-4x+5y=27
x-6y=-2
substitute x=-2+6y
I am again using : x-6y=-2
x(-2+6y)-6y=-2
-2+y=-2
y=-2÷2
y=-1
finding x:(substituting y=-1)
x-6y=-2
x-6(-1)=-2
x+6=-2
x=-2-6
x=-8
check:
-4x+5y=27
-4(-8)+5(-1)=27
32+-5=27

The Viking football team won 4 out of every 5 of their football games. If they played 20 games, how many games did they lose? help me plzz i give you brianlist
Answer: The Viking football team lost 4 games.
Step-by-step explanation: Since the Vikings WON 4/5 of their 20 games, you need to find the other 1/5. That means you need to find 1/5 of 20. Divide 20 and 5. The final answer is 4.

What is the length of the hypotenuse of an isosceles right triangle (both legs congruent), if the leg is 8?
Answer: 8 sqrt 2
Step-by-step explanation:
An isosceles right triangle is also known as a 45-45-90 triangle. In a 45-45-90 triangle, both the legs are equal, and the hypotenuse is the leg of the triangle multiplied by the square root of 2.
Another way to solve this is to us the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, a^2 + b^2 = c^2, with c being the hypotenuse. Since a and b are both equal to 8, 8^2 + 8^2 = c^2. This simplifies to 128 = c^2. By taking the square root of both sides, you get sqrt 128 = c. This simplifies to c = 8 sqrt 2

The area of a rectangle is 72 sq units. One side length is 9 units. What is the other side length
Based on the area of the rectangle and the length of one side, the length of the other side is 8 units
The area of a rectangle is calculated as:
Area = Length x Width
The length is already given so the width is:
72 = 9 x Width
Width = 72 / 9
Width = 8 units
In conclusion, the other side length is 8 units.

Answer:
The length of other side of rectangle is 8 unit.
Step-by-step explanation:
Given :
[tex]\pink\star[/tex] Area of rectangle = 72 sq units[tex]\pink\star[/tex] Lenght of rectangle = 9 unitsTo Find :
[tex]\pink\star[/tex] Breadth of rectangleUsing Formula :

What is the equation of the solid boundary line?
and can you explain how you solved it?
Answer:
solid boundary line: y = -1/2 x + 4
shaded area: y ≥ -1/2 x + 4 and y < x+1
Step-by-step explanation:
solid boundary line pass (0,4) (2,3)
slope (m) = (3-4) / (2-0) = -1/2
y intercept (b) = 4
equation: y = mx + b y = -1/2 x + 4
system: y ≥ -1/2 x + 4
dotted line: (0,1) (2,3)
m = (3-1) / (2-0) = 1
b = 1
equation: y = x + 1
system: y < x+1
