Write an exponential model given two points. (3, 55) and (4, 70)
Answers
The exponential equation that passes through these two points is:
y = 26.678*(14/11)^x
How to write an exponential equation with these two points?A general exponential equation is:
y = A*(b)^x
If we know the two points (3, 55) and (4, 70), then we can write two equations:
55 = A*(b)^3
70 = A*(b)^4
If we take the quotient between the second equation and the first one, then we get:
70/55 = (A*(b)^4)/(A*(b)^3)
70/55 = b
14/11 = b
Then we can write:
55 = A*(14/11)^3
(11/14)^3*55 = A
26.678 = A
Then the exponential equation is:
y = 26.678*(14/11)^x

In the figure, m∠ 1=(3 x)° and m ∠2=(x+48)°
(a) Write an equation to find x. Make sure you use an = sign in your answer.
(b) Find the degree measure of each angle.
m ∠ 1=____°
m ∠ 2=____°
Answers
If m∠ 1=(3 x) degrees and m ∠2=(x+48) degrees
The equation to solve the value of x is
3x = x+48
The value of x = 33
The angle 1 = 99 degrees
The angle 2 = 81 degrees
The measure of angle 1 = 3x degrees
The measure of angle 2 = x + 48 degrees
The sum of the angles on a straight line is add up to 180 degrees. Therefore angle 1 and angle 2 are supplementary angles.
∠1 + ∠2 = 180 degrees
Substitute the values in the equation
3x + x + 48 = 180
4x + 48 = 180
4x = 180 - 48
4x = 132
x = 132/4
x = 33
Part b
Then the measure of angle 1 = 3x
= 3 × 33
= 99 degrees
The measure of angle 2 = x + 48
= 33 + 48
= 81 degrees
Therefore, the equation to solve x is 3x = x + 48 and the measure of angles 1 and 2 is 99 degrees and 81 degrees respectively

Use slope-intercept form to write an equation of a line passing through the given point and having the given slope. Express the answer in standard form. P(-4,-9); m= -3/4
Answers
Answer:
4y = -3x - 48
Step-by-step explanation:
y - y1 = m(x - x1)
y1 = -9 x1= -4 m = -3/4
y -(-9) = -3/4(x -(-4)
y + 9 = -3/4(x + 4)
y + 9 = -3/4x -12/4
multiply through by 4
4y + 36 = -3x -12
4y = -3x -12-36
4y = -3x -48 in the form y = mx + c
whats the equation of a line that passes through point (-1,3) with slope of 1
Answers
The equation of the line that passes through the point (-1, 3) with a slope of 1 is y = x + 4.
To find the equation of a line that passes through the point (-1, 3) with a slope of 1, we can use the point-slope form of a linear equation.
The point-slope form of a linear equation is given by:
y - y1 = m(x - x1)
where (x1, y1) represents the coordinates of a point on the line, and m represents the slope of the line.
Using the given point (-1, 3) and slope 1, we substitute these values into the point-slope form equation:
y - 3 = 1(x - (-1))
Simplifying:
y - 3 = x + 1
Now, we can rewrite the equation in the standard form:
y = x + 4
Therefore, the equation of the line that passes through the point (-1, 3) with a slope of 1 is y = x + 4.

Finde the value of x in the proportion ( 5x+ 1 ):3 =(2x +2): 7(6 x) = (4x) :7
Answers
In the proportion (5x + 1):3 = (2x + 2):7, the value of x is -1/29.
In the proportion (6x):(4x) = 7, there is no value of x that satisfies the proportion.
To find the value of x in the given proportions, let's solve them one by one:
(5x + 1) : 3 = (2x + 2) : 7
To solve this proportion, we can cross-multiply:
7(5x + 1) = 3(2x + 2)
35x + 7 = 6x + 6
Subtracting 6x from both sides and subtracting 7 from both sides:
35x - 6x = 6 - 7
29x = -1
Dividing both sides by 29:
x = -1/29
Therefore, the value of x in the first proportion is -1/29.
(6x) : (4x) = 7
To solve this proportion, we can simplify the left side:
6x / 4x = 7
Dividing both sides by 2x:
3/2 = 7
This equation is not true, as 3/2 is not equal to 7.
Therefore, there is no value of x that satisfies the second proportion.
In summary, the value of x in the proportion (5x + 1) : 3 = (2x + 2) : 7 is -1/29, and there is no value of x that satisfies the proportion (6x) : (4x) = 7.

How to Solve Functions Using a Graph?A function is graphed by plotting the input values on the x-axis against the output values on the y-axis. This means all input values are on the x-axis, and their corresponding output values are on the y-axis.
To find the output value when an input value is given as 4, we need to trace the output value that corresponds to x = 4 on the graph.
Using the graph in the diagram, we know the following:
When the input value is x = -9, the output value is y = 1.
When the input value is x = -5, the output value is y = 1.
When the input value is x = -2, the output value is also y = 1.

To obtain the result in each case, you must replace the variable (n) by the value that appears in the second case, I'll explain it with the first exercise:
1. f(n) = 5n + 8 f(4) = ?As you can see, in the second doesn't appear f(n), but f(4), that means you must replace the "n" in the equation by 4, if we do this, we obtain:
1. f(4) = 5*(4) + 8f(4) = 20 + 8f(4) = 28The first answer is 28, now we'll continue with the next exercises:
2. f(n) = -2n + 1f(10) = -2*(10) + 1f(10) = -20 + 1f(10) = -193. f(n) = 6n - 3f(-5) = 6*(-5) - 3f(-5) = -30 - 3f(-5) = -334. f(n) = -nf(9) = -9In this form, you can prove the answers are: 28, -19, -33, and -9 respectively.

Answers
The length of the towel bar is 9.5 inches.
How to solve the equation?Length is used to measure distance, In the International System of Quantities, a quantity with the distance dimension is referred to as length. The majority of measurement systems select a base unit for length from which all other units are derived. The metre serves as the International System of Units' fundamental unit of length.
Suppose, the length of the towel bar is x inches
The distance from each end of the towel bar to the end of the door is 9
inches. So, the total width of the door will be:[(x+(9*2)]=(x+18) inches
Given that, the width of the door is 27 inches 27.5 So, the equation will be.
x+18=27.5
x=27.5-18=9.5
Thus, the length of the towel bar will be 9.5 inches.

Triangle XYZ is rotated 90° counterclockwise about the origin to produce X'Y'Z'. What are the coordinates of X'Y'Z'?
Answers
Answer:
59
Step-by-step explanation:
6 plus 4 equals 8 plus 9
Identify the coordinates of each vertex of triangle XYZ.
Apply the 90° counterclockwise rotation rule, which states that when rotating a point 90° counterclockwise about the origin, the new coordinates of the point will be (-y, x).
Substitute the coordinates of each vertex into the rotation rule to find the coordinates of the corresponding vertex in X'Y'Z'.
For example, let's say that the coordinates of triangle XYZ are:
X = (2, 3)
Y = (-1, 4)
Z = (0, -2)
To find the coordinates of X'Y'Z', we can apply the rotation rule to each vertex as follows:
X' = (-3, 2)
Y' = (-4, -1)
Z' = (2, 0)
Therefore, the coordinates of X'Y'Z' after rotating triangle XYZ 90° counterclockwise about the origin are:
X' = (-3, 2)
Y' = (-4, -1)
Z' = (2, 0)
Note that the order of the vertices may change after the rotation, but the coordinates of each vertex will correspond to the same vertex in the original triangle.
