Find the slope of the line passing through the pair of points.
(-4,5) and (0, 2)
Answer:
y = 3/-4x + 2
Step-by-step explanation:
Answer:
slope = [tex]-\frac{3}{4}[/tex]
Step-by-step explanation:
1) To find the slope between a pair of points, use the slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through. [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line also passes through. We know the line passes through (-4,5) and (0,2). So, substitute their x and y values for the formula (following the appropriate order) and solve:
[tex]\frac{(2)-(5)}{(0)-(-4)} \\= \frac{2-5}{0+4} \\= \frac{-3}{4}[/tex]
Thus, the slope is [tex]-\frac{3}{4}[/tex]

A rectangular plaque at a historical museum is 5/6 and 2/3 yard wide how much is the plaque longer than it is wide
Answer:
1/6 yard
Step-by-step explanation:
A rectangular plaque at a historical museum is 5/6 and 2/3 yard wide how
Given data
Length of plaque= 5/6 yard
Width of plaque= 2/3 yard
The difference between the Length and the width is
=5/6-2/3
=5-4/6
=1/6 yard
Hence the Lenght is 1/6 yard longer than the width

302.833 rounded to the nearest whole number
Answer:
303
Step-by-step explanation:
Step-by-step explanation:
When rounding a decimal to the nearest whole number, we look at the tenths place. If it is {5,6,7,8,9} we round the ones place up. If it is {0,1,2,3,4} the ones place stays the same.
For 302.833, the tenths place is 8.
Therefore we round 302.833 up to 303.
The answer is 303.

The solution to this given system of equations is (x,y) = (0.4,15).
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
y - 13 = 5x
y - 5x = 12
Now,
To do this, we can add both equations together to eliminate x:
(y - 13) + (y - 5x) = 5x + 12 2y - 13 - 5x = 17 2y = 30 y = 15
Now that we have found y, we can substitute it into either equation to find x. For example:
15 - 13 = 5x 2 = 5x x = 0.4
Therefore, by the given system of equations the answer will be (x,y) = (0.4,15).

Describe the translation needed to obtain the graph of g(x)=6^x-9 from the graph of f(x)=6^x.
Answer:
Step-by-step explanation:
I am not sure if you wanted to ask this
f(x) = 6^x becomes g(x)= (6^x ) -9 so it went DOWN 9 units
or this
f(x) = 6^x becomes g(x)= 6^(x -9) so it went RIGHT 9 units
The entry tickets at a community fair cost $5 for children and $10 for adults. On a certain day 1000 people entered in the fair and $7,100 is collected. How many adults and how many children were at the fair?
Answer:
C = 580 children.
A = 420 adult.
Step-by-step explanation:
Let the number of children be C.
Let the number of adult be A.
Translating the word problem into an algebraic equation, we have;
A + C = 1000 .......equation 1
10A + 5C = 7100 .......equation 2
A = 1000 - C .......equation 3
Substituting eqn 3 into eqn 2, we have;
10(1000 - C) + 5C = 7100
10000 - 10C + 5C = 7100
10000 - 7100 = 10C - 5C
2900 = 5C
C = 2900/5
C = 580 children.
Now, to find the value of A.
From equation 3;
A = 1000 - C
A = 1000 - 580
A = 420 adult.

Solve 2x=54xˆ(2/3)
Please, I need the step by step working to find the value of x
Answer:
x = 19683 or x = 0
Step-by-step explanation:
Solve for x:
2 x = 54 x^(2/3)
Hint: | Isolate the radical to the left hand side by reversing the equality.
2 x = 54 x^(2/3) is equivalent to 54 x^(2/3) = 2 x:
54 x^(2/3) = 2 x
Hint: | Eliminate the power on the left hand side.
Raise both sides to the power of three:
157464 x^2 = 8 x^3
Hint: | Move everything to the left hand side.
Subtract 8 x^3 from both sides:
157464 x^2 - 8 x^3 = 0
Hint: | Factor the left hand side.
Factor x^2 and constant terms from the left hand side:
-8 x^2 (x - 19683) = 0
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by -8:
x^2 (x - 19683) = 0
Hint: | Find the roots of each term in the product separately.
Split into two equations:
x - 19683 = 0 or x^2 = 0
Hint: | Look at the first equation: Solve for x.
Add 19683 to both sides:
x = 19683 or x^2 = 0
Hint: | Look at the second equation: Eliminate the exponent.
Take the square root of both sides:
Answer: x = 19683 or x = 0

Answer:
We conclude that:
h(f(-1)) = -2
∴ option D i.e. -2 is correct.
Step-by-step explanation:
Given
f(x) = 4x² - 1
g(x) = 1/2x + 5
h(x) = 2(x - 4)³
To determine
h(f(-1)) = ?
In order to determine h(f(-1)) first we need to determine f(-1).
substitute x = -1 in the function f(x) = 4x² - 1
f(-1) = 4(-1)² - 1
f(-1) = 4(1) - 1
f(-1) = 4-1
f(-1) = 3
so
h(f(-1)) = h(3)
now substitute h = 3 in the function h(x) = 2(x - 4)³
h(x) = 2(x - 4)³
h(3) = 2(3 - 4)³
h(3) = 2(-1)³
h(3) = 2(-1)
h(3) = -2
Thus,
h(f(-1)) = h(3) = -2
Hence, we conclude that:
h(f(-1)) = -2
∴ option D i.e. -2 is correct.
