What is the domain and range of It’s
h(x)= -1/2(x-4)^2 +3
Answer:
Domain: [ − 3 ,∞ )
Range: ( − ∞ , 0 ]
Step-by-step explanation:
h ( x ) = − √ x + 3
the domain:
x +3 ≥ 0 x ≥ − 3
in interval form:
[ − 3 , ∞ )
the range:
lowest possible value under the square root sign is zero, thus:
y ≤ 0

Find the smallest square number divisible by each of these numbers 6,9,and 15
900
Step-by-step explanation:6 = 2×3
9 = 3²
15 = 3×5
lcm = 2×3²×5 = 90
to have a square number multiple of 90 we have to multiply by 2 and 5
2×3²×5 × 2×5 = 2²×3²×5² = (2×3×5)² = 30² = 900

Which of the following answer choices shows which numbers from the list below are less than - 0.94?
Answer:
-2.23, -2 2/5, -0.95

-15/16 = -0.9375 (greater than -0.94)
0.24 (greater than -0.94)
-2.23 (less than -0.94)
97% = 0.97 (greater than -0.94)
-2 2/5 = -2.4 (less than -0.94)

The price for the amount of fuel that Roselyn will use for the entire drive is $25
What is an Equation?An equation is a mathematical statement formed when two expressions are equated using an equal sign.
The equations are useful in the determination of unknown parameters.
The equations are of various types, such as Trigonometric equations, and quadratic equations.
Roselyn's family lives 150 km away.
Her average speed is 60km/h
The car tank has 20 L of fuel at the beginning of the the drive.
Fuel efficiency is 6km/ L.
The cost of the fuel is $0.60/L.
The total drive is 150km.
The 6km of distance requires 1 L of fuel
Then 150 km of the distance requires
= 150 * 1 / 6
= 150/6
= $25.

Find all numbers such that 18 plus 4 times the number is less than 30.
Answer:
The numbers are 2,1,0,-1,-2,..............etcStep-by-step explanation:
This is actually a word problem
step one:
let the maximum number be x
18+4x<30
4x<30-18
4x<12
divide both sides by 4 we have
4x<12
x<3
step two:
From this analysis, we can see that all possible numbers are real numbers less than 3 that is 2,1,0,-1,-2,..............etc
what is the sum of the equation? 15x-5x+5y+5y
Hey there!
ANSWER: [tex]10x+10y[/tex]EXPLANATION:[tex]15x-5x+5y+5y[/tex]
To solve, first subtract the 2 numbers with x.
[tex]15x-5x=10x[/tex]
Now let's add the two numbers y.
[tex]5y+5y=10y[/tex]
So the answer will be 10x + 10y because 15x-5x is equal to 10x and 5y + 5y is equal to 10y. And then you just add the x and y.

2. 1/3 (1 third)
3. -3
4. -1\2 (negative one and a half)
5.-4
6. 1.66666
Step-by-step explanation:
1. Let's solve your equation step-by-step. ( x + 5 ) ( x − 2 ) = 0 Step 1: Simplify both sides of the equation. x 2 + 3 x − 10 = 0 Step 2: Factor left side of equation. ( x − 2 ) ( x + 5 ) = 0 Step 3: Set factors equal to 0. x − 2 = 0 or x + 5 = 0 x = 2 or x = − 5. <—— this is for the first explanation
2. Step 1: Simplify both sides of the equation. 6 x 2 + 13 x − 5 = 0 Step 2: Factor left side of equation. ( 3 x − 1 ) ( 2 x + 5 ) = 0 Step 3: Set factors equal to 0. 3 x − 1 = 0 or 2 x + 5 = 0 x = 1 3 or x = − 5 2 Answer: x = 1 3 or x = − 5 2
<———— this is for the second explanation
3.Step 1: Factor left side of equation. ( x + 1 ) ( x − 4 ) = 0 Step 2: Set factors equal to 0. x + 1 = 0 or x − 4 = 0 x = − 1 or x
<———- this is for the third explanation
4.Step 1: Factor left side of equation. ( 2 x + 1 ) ( x − 3 ) = 0 Step 2: Set factors equal to 0. 2 x + 1 = 0 or x − 3 = 0 x = − 1 2 or x = 3
<—————- this is for the fourth explanation
5. Step 1: Add 16 to both sides. x 2 − 16 + 16 = 0 + 16 x 2 = 16 Step 2: Take square root. x = ± 16 x = 4 or x = − 4
<—————- this is for the fith explanation
6. Step 1: Add 25 to both sides. 9 x 2 − 25 + 25 = 0 + 25 9 x 2 = 25 Step 2: Divide both sides by 9. 9 x 2 9 = 25 9 x 2 = 25 9 Step 3: Take square root. x = ± 25 9 x = 1.666667 , − 1.666667
<—————- this is for the sixth explanation

Think about the rule when multiplying powers together.
When multiplying two powers that have the
same base, simply add their exponents.
In this problem, each power has a base
of a and our exponents are m and n.
So adding these exponents together, we have a^m + n.

Chase watched a movie about aliens who never stop growing. Every alien is 10 centimeters tall at birth and grows exactly 8 centimeters each year.
Let y represent the number of years since birth and h represent the alien's height in centimeters.
Complete the equation that represents the relationship between y and h.
y h
5 50
6 58
7 66
8 74
h=y+
Answer:
Step-by-step explanation:
Let the height (the dependent variable) be h.
Let the independent variable (x) be y
h = 8y + 10
So at birth, these creatures are 10 cm long. At each birthday, they are another 8 cm.
Take the fifth year which is where the table begins.
y= 8*5 + 10
y = 40 + 10
y = 50 cm which is exactly what you got.

What’s the answer
Answer:
[tex]x<-8[/tex]
Step-by-step explanation:
So we have the inequality:
[tex]3x-1>4x+7[/tex]
Add 1 to both sides. The left side cancels:
[tex]3x>4x+8[/tex]
Subtract 4x from both sides. The right side cancels:
[tex]-x>8[/tex]
Divide both sides by -1. Since we're dividing by a negative, we flip the sign:
[tex]x<-8[/tex]
And we're done!
Our solution is all numbers less than -8.
Answer:
x = -8
