Answer: I think it’s D
Step-by-step explanation:
Answer:
The domain is a set/group of x-values. The range is a set/group of y-values. The first option is not true because there are x-values which are greater than 0 (right side of graph). The second option is not true because the set of y-value stops before it hits the y=0. The third option is not true because there are no y-values which are less than 0 (bottom of graph). The fourth option is correct because the x-values stretch from -infinity on the left side of the graph to positive infinity of the right side of the graph.

Answers
Answer:
Y = -3
Step-by-step explanation:
First lets use this equation to find the slope of the line:
Y2-Y1/X2-X1
Plug in our values:
(-3+3)/(4-2) = 0/2
The slope is undefined because it cannot be 0.
The Y values of the ordered pairs stay the same so we can see that the graph will stay on the Y value -3.
We would graph this line horizontally on Y = -3

In the park, there are some cats and dogs. The number of cats’ feet is double the number of the dogs’ noses. The number of cats is how many times the number of dogs? Let x be the number of cats, and y be the number of dogs. Write the expression that will help you to solve the problem (expression here). The number of cats is what times the number of dogs.
Answers
Answer:
2y=x
Step-by-step explanation:
Normally, if there were the same amount of cats and dogs, the cats' feet would be quadruple the dogs' noses. But, the question states that it is double the dogs' noses. 2 x 2=4, so there are twice as many dogs as cats.

PROOF! Prove Theorem: If two lines are perpendicular, then they form congruent adjacent angles. Given: Line AB is perpendicular to line CD. Angle 1 and angle 2 are a linear pair. Prove: Angle 1 is congruent to angle 2.
Answers
Answer:
From construction, we construct point M as the center of the figure. According to the linear pair postulate, we know that the sum of the angles on a straight line equal to 180 degrees. Therefore, we know that the other angles have to be 90 degrees. Therefore the angles are congruent because all right angles are congruent.

Since 12 is a multiple of 3, we can multiply the 3 by 4. Now what you do to the denominator you must do to the Numerator. 1 x 4 = 4

9/12 of the shirts are either striped or plaid

a 10kg box putting pushed with a force of 24 Newtons and a fraction of 12N. Determine coefficient of Friction and Determine acceleration of the Box
PLEASE HELP
Answers
Assuming the force is applied horizontally over a flat surface, the net horizontal force is
F (h) = 24 N - 12 N = (10 kg) a
Solve for the acceleration a :
12 N = (10 kg) a
a = 1.2 m/s²
Meanwhile, the net vertical force is zero since the box of only moving horizontally.
F (v) = n - (10 kg) g = 0
where n is the magnitude of the normal force exerted upward by the surface. We see that
n = (10 kg) (9.8 m/s²)
n = 98 N
The friction force has a magnitude that is proportional to the normal force,
12 N = μ (98 N)
where μ is the coefficient of kinetic friction. Solve for μ :
μ = (12 N)/(98 N)
μ ≈ 0.12

How:
- As you can see the line goes through the y axis at 2- so we can substitute the c in y=mx + c for 2
- To find the gradient use two points on the line and count across and up, I used (-4,-6) and (0,2) which was 2 across and 4 up: 4 divided by 2 is 2 giving us the gradient to substitute the 2 as m into y=mx+c
That gives us y=2x+ 2

Six less than x
I'm in 8th
Answers
Answer
I found this. Does this help?
Step-by-step explanation:
If this is an inequality (6 is less than x, or 6 < x), then x is an integer or other value greater than 6.
The variable statement "6 less than x" is (x - 6)
This is a value (variable and constant) where the value of x is determined by an equation
such as x-6 = 4 (x is positive 2) or y = x-6 (y is 6 less than x).
