Answer:
h(2)=8
Step-by-step explanation:
The problem basically asks you to substitute 2 in, hence h(2).
Here is your base equation.
h(x)=-x^2+6x
Plug in 2.
h(2)=-2^2+6(2)
Simplify, using PEMDAS.
h(2)=-4+12
h(2)=8
There's your answer!

sam buys a rare stamp for his stamp collection at an auction. he buys the stamp for 920£ the stamp increased in value by 7% in each of the first 2 years decreased in value by 4% in the third year
Answers
The value of the stamp at the end of the third year is £976.31.
How to calculate the value?From the information, Sam buys a rare stamp for his stamp collection at an auction. he buys the stamp for 920£ the stamp increased in value by 7% in each of the first 2 years.
First year value:
= 920 + (2% × 920)
= 938.4
Second year value:
= 938.4 + (2% × 938.4)
= 957.168
Third year value:
= 957.168 + (2% × 957.168)
= £976.31

Answers
Answer:(-4 - 0.7 - 1)÷-4 = 57/40 = 1 17/40 = 1.425
Spelled result in words is fifty-seven fortieths (or one and seventeen fortieths).
How do you solve fractions step by step?
Conversion a decimal number to a fraction: 0.7 = 7/10 = 7/10
a) Write down the decimal 0.7 divided by 1: 0.7 = 0.7/1
b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
0.7/1 = 7/10
Note: 7/10 is called a decimal fraction.
c) Simplify and reduce the fraction
7/10 = 7 * 1/10 * 1 = 7 * 1/10 * 1
Subtract: -4 - 0.7 = -4/1 - 7/10 = -4 · 10/1 · 10 - 7/10 = -40/10 - 7/10 = -40 - 7/10 = -47/10
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(1, 10) = 10. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 10 = 10. In the following intermediate step, the fraction result cannot be further simplified by canceling.
In other words - minus four minus seven tenths = minus forty-seven tenths.
Subtract: the result of step No. 2 - 1 = -47/10 - 1 = -47/10 - 1/1 = -47/10 - 1 · 10/1 · 10 = -47/10 - 10/10 = -47 - 10/10 = -57/10
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(10, 1) = 10. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 1 = 10. In the following intermediate step, the fraction result cannot be further simplified by canceling.
In other words - minus forty-seven tenths minus one = minus fifty-seven tenths.
Divide: the result of step No. 3 : (-4) = -57/10 : (-4) = -57/10 · -1/4 = -57 · (-1)/10 · 4 = 57/40
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of -4/1 is 1/-4) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, the fraction result cannot be further simplified by canceling.
In other words - minus fifty-seven tenths divided by minus four = fifty-seven fortieths.

[tex]\frac{6x}{x^2-9}[/tex] ÷ [tex]\frac{8}{4x-12}[/tex]
Factorise the denominators of both fractions
x² - 9 = x² - 3² = (x - 3)(x + 3) ← difference of squares
4x - 12 ← factor out 4 from each term

Then rewrite as
[tex]\frac{6x}{(x-3)(x+3)}[/tex] ÷ [tex]\frac{8}{4(x-3)}[/tex] ← cancel 8 and 4 by 4

Jalil mixed cup of water with cups of sugar. How many more cups of water than sugar did he use in his mixture?
the question has no numbers what do i do
Answers
Answer:
[tex]1\frac{11}{24}[/tex] cups more water than sugar
Step-by-step explanation:
Question: Jalil mixed 3/8 cup of sugar with 11/6 cups of water. How many more cups of water than sugar did he use in his mixture.
Answer:
Jalil mixed the number of cups of sugar = [tex]\frac{3}{8}[/tex]
with the number of cups of water = [tex]\frac{11}{6}[/tex]
We have to find the additional amount of water that is used in his mixture.
So we will subtract the amount of sugar from the amount of water.
[tex]\frac{11}{6}[/tex]- [tex]\frac{3}{8}[/tex]
= [tex]\frac{44-9}{24}[/tex]
= [tex]\frac{35}{24}[/tex]
= [tex]1\frac{11}{24}[/tex] cups
[tex]1\frac{11}{24}[/tex] cups more water is used in this mixture.

Answers
Answer:
Step-by-step explanation:
Since B is the midpoint, AB must be equal to BC.
AB = BC
7x - 4 = 3x + 32
Isolate the variable
7x - 4 = 3x + 32
4x = 36
x = 9
Now solve for one side.
AB = 7x - 4
AB = 7(9) - 4
AB = 59
Since both sides are equal, finding AC just means multiplying one side by 2.
AC = AB * 2
AC = (59) * 2
AC = 118
You can double check by finding the other side and multiplying by 2.
BC = 3x + 32
BC = 3(9) + 32
BC = 27 + 32
BC = 59
AC = BC*2
AC = 59*2
AC = 118

write the equation of a line that is parallel to y=12-5x and passes through the point (1,-7)
Answers
Answer:
y= -5x-2
Step-by-step explanation:
Parallel equations have the same slope, so we know our slope will be -5. To get our y-intercept, we need to plug in our slope. 1 times -5 is -5, so we need to figure out how to get from -5 to -7. We're going to subtract 2, so the y-intercept is -2.
The equation of the line parallel to y=12-5x and passes through the point (1,-7) will be y= -5x-2.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the equation of a line that is parallel to y=12-5x and passes through the point (1,-7).
The slope of the parallel lines is always the same. The slope of the line will be -5.
The y-intercept of the line will be calculated as,
y = mx + c
-7 = -5(1) + c
c = -7 + 5
c = -2
The equation of the line will be written as,
y = mx + c
y = -5x - 2
Therefore, the equation of the line parallel to y=12-5x and passes through the point (1,-7) will be y= -5x-2.
