What is the range of the function y = startroot x 5 endroot?
Answers
The domain of the function is [-5,0) and the range of the function y = startroot x 5 endroot is [0,∞)
What is range of function?Range of a function is the set of all the possible output values which are valid for that function.
The function given in the problem is,
[tex]y=\sqrt{x+5}[/tex]
This function is defined when the value of √(x+5) is greater than or equal to 0.
[tex]\sqrt{x+5}\ge0[/tex]
Solve it further,
[tex]\sqrt{x+5}\ge0\\(x+5)\ge0\\x\ge-5[/tex]
Thus, the domain of the equation is [-5,0). Now for the range,
[tex]x+5\ge0\\\sqrt{x+5}\ge0\\y\ge0[/tex]
Thus the range is [0,∞).
Hence, the domain of the function is [-5,0) and the range of the function y = startroot x 5 endroot is [0,∞)

X-intercept: ( __ , __ )
Answers
Answer:
x-intercept : (-1.2,0)
y-intercept : (0,-0.7)
Step-by-step explanation:
Hello!
An x-intercept is when the y-value is 0, and a y-intercept is when the x value is 0.
Another way to think about it, x-intercepts intersect with the x-axis, while the y-intercept intersects with the y-axis.
A coordinate, a point on a graph, is written as (x,y) or x-position and y-position.
x-intercept : (-1.2,0)

1.) Mrs. Tom is having triplets. What is the probability that all three children will be boys?
Answers
Answer:
1/3
Step-by-step explanation:
due to her having triplits it will be a 1/3 chance that they will all be boys because you need to take in account the three children
Answer:
Step-by-step explanation:
There are 8 different ways that the order of the children is 1/8 for each one.
So for boy * boy * boy = 1/2 * 1/2 * 1/2 = 1/8
All of the other possibilities also produce 1/8 because each child has a possibility of 1/2 to be a boy or a girl.
Solve the equation 4(x + 5) = 9x + 4x − 34, and show your work
Answers
Answer:
x = 6
Step-by-step explanation:
: 4(x + 5) = 9x + 4x − 34
Combine Like Terms:
- 4x + 20 = 9x + 4x − 34
- 4x + 20 = 13x − 34
Subtract 20 from both sides:
- 4x + 20-20 = 13x − 34-20
Subtract The numbers:
= 4x = 13x - 54
Subtract 13x from both sides:
= 4x-13x = 13x - 54-13x
Combine Like terms:
- 9x = -54
Divide both sides by the same factor:
-9x / -9 = -54 / -9

Answer:

Step-by-step explanation:
the 50 miles don't really matter in this situation. 180$ per hour will be 180h (as we don't know the number of hours used) and the 50$ gas fee, which is what C is representing.
Answer:
C: C = 180h + 50

180 per hour, with h representing how many hours, and then you need a $50 gas fee. So, the answer would be C = 180h + 50

Answer:
x=30
Step-by-step explanation:
you would call those alternate exterior angles meaning that they are the same angle, so all you have to do is reverse the equation meaning you do 75-15=60 and you would then divide by 2 to get X so 60/2=30, so x=30
Answer:
x = 30
Step-by-step explanation:
2x+15 should be vertical to angle 5
75 is vertical to angle 4.
If we were to look at angles 4 and 5 those are alternate interior which means they have to be congruent.
2x+15=75
2x=75-15
2x=60

Complementary angles are angles that sum up to 90°.
Here,
Angle P = 2xAngle Q = 7xThen,
Angle P + Angle Q = 90°
2x + 7x = 90°
9x = 90°

the length of a rectangle is 5 cm more than twice a number. the width is 4cm less than the same number. if the area of the rectangle is 15cm2, find the number
Answers
A = 15 (Area is 15)
L = 2x + 5 (length is 2 times a number plus another 5)
w = x - 4 (width is 4 less than that number
Plug in the values:
15 = (2x + 5)(x - 4)
FOIL
15 = 2x2 - 8x + 5x - 20
simplify:
15 = 2x2 - 3x - 20
Subtract 15
0 = 2x2 - 3x - 35
Factor out the quadratic. We know that one number has to be 7 and the other 5 so that they multiply together to make 35, and that one of them has to be negative so that it's actually -35.
That means we have m * n = -35
We also need it set up so that so that 2m + n = -3:
2 * -5 + 7 = -3
0 = (2x + 7)(x - 5)
So:
0 = 2x + 7, or 0 = x - 5
x = -7/2 or 5
We cannot have a negative length, so x = 5
Check:
15 = (2 * 5 + 5) (5 - 4)
15 = 15 * 1
