Answer:
67 square units
Step-by-step explanation:
Circumference/pi = diameter
29/3.14 = 9.24
Radius = 9.24/2 = 4.62
A = pi * r^2
A = 3.14 * 4.62^2 = 67 square units
Subtract the linear expressions. (−2.6x+4.2)−(3.9x+2.5) What is the difference? Enter your answer in the box.
Answer:
-13x/2+1.7
Step-by-step explanation:
The difference of the given expression is - 6.5 x + 1.7.
Given that, (−2.6x+4.2)−(3.9x+2.5).
What is the subtraction of expressions?To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.
Now, (−2.6x+4.2)−(3.9x+2.5)
= (-2.6x-3.9x)+4.2-2.5
= - 6.5 x + 1.7
Therefore, the difference of the given expression is - 6.5 x + 1.7.

A retiree has $200,000 to invest and needs to make $13,000 with her investments. If she can invest in government bonds at 6% or investment-grade bonds at 8%, how much should she invest in each?
Answer:
$50,000 at 8%; $150,000 at 6%
Step-by-step explanation:
$50,000 x .08 = $4000
$150,000 x .06 = $9000
$4000 + $9000 = $13,000
I WILL GIVE BRAINLIEST. PLEASE ANSWER ILL GIVE A LOT OF POINTS
To graph a straight line only 2 points are required
although 3 points are better (in case of error with other 2 .)
To find the y-intercept let x = 0 : hence y = - 5 ie (0 , - 5 )
To find the x-intercept let y = 0 : hence -x - 5 = 0 so x = - 5
ie ( - 5 , 0 )
These 2 points will allow the line to be drawn but a 3rd
is preferable. Choose any value for x and evaluate y.
choose x = 2 : then y = - 2 - 5 = - 7 ie (2 , - 7 )
Plot these 3 points: (0 , - 5 ) , (- 5 , 0 ) and (2 , - 7 ) and
draw a straight line through them .

32 is 4 times as much as what number
Answer: 8
Step-by-step explanation:
The 4 times of the number 8 results to 32.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values. In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
32 is 4 times as much as what number
let the number be x.
So, 4 times of x = 32
4x = 32
Divide both side by 4.
4x/4 = 32/4
x= 8
Hence, the 4 times of the number 8 results to 32.

identify the errors made in finding the inverse of y = x2 + 12x. An image shows a student's work. Line 1 is x = y squared + 12 x. Line 2 is y squared = x minus 12 x. Line 3 is y squared = negative 11 x. Line 4 is y = Start Root negative 11x End Root, for x greater-than-or-equal 0.
solving for the inverse of y = x² + 12x
Line 1: x = y² + 12 x.
Line 2 y² = x - 12 x.
Line 3 is y²= - 11 x.
Line 4 is y = √(- 11x) for x ≥ 0.
The error lies in Line 1. All x's have to be switched with y's and vice versa for the method to work.
As such Line 1 should be x = y² + 12y NOT (x = y² + 12 x)
Since Line one is wrong, it messes with all the other lines.
Point G is the centroid of triangle ABC. AG = (5x + 4) units and GF = (3x – 1) units.
Triangle A B C has centroid G. Lines are drawn from each point to the midpoint of the opposite side to form line segments A F, B D, and C E. The length of line segment A G is 5 x + 4 and the length of line segment G F is 3 x + 1.

Based on the given diagram, the length of FA is 51 units
Find the diagram attached. From the diagram;
AG = 2GF
Given that:
AG = 5x + 4
GF = 3x - 1
Substitute the given parameters into the formula;
5x + 4 = 2(3x - 1)
5x + 4 = 6x - 2
5x - 6x = -2 - 4
-x = -6
x = 6
Get the FA = 5x + 4 + 3x - 1
Substitute the value of x into the expression:
FA = 8x + 3
FA = 8(6) + 3
FA = 48 + 3
FA = 51 units
Hence the length of FA is 51 units

Answer:
10
Step-by-step explanation:
We know that a = 4 and b = 6, and we are trying to find the answer to both of them added, so to get a + b, we can substitue the values of a and b by their numbers. So,
a + b
Is the same as
4 + 6, which equals 10.
Therefore, the value of a+b is 10

calculate the area of the shape
Step-by-step explanation:
Area of a trapezium = ¹/₂ (a + b) h
But the height isn't given. So we have to solve for it.
h = √(10² - 6²) [using the Pythagorean theorem]
= 8
∴ Area of the shape = ¹/₂ (13 + 28) 8
= 164 u²

Given f(x) = 10x.
a. Graph b(x) = f(x) - 30. Then complete the table of corresponding points for b(x)
Answer:
b(x) = 10x - 30
Step-by-step explanation:
You are given that f(x) = 10x, so in-order to graph the equation, you must plugin the value of f(x).
This gives the equation b(x) = 10x - 30
or y= 10x - 30
The slope of the linear function → b(x) = f(x) - 30 is [m] = 10 and the [y] intercept is at [c] = - 30
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is the function -
f(x) = 10x
We have the function -
f(x) = 10x
Now -
b(x) = f(x) - 30
b(x) = 10x - 30
This is the equation of a straight line.
Refer to the graph attached.
The slope of the line is [m] = 10
The [y] intercept is at [c] = - 30
Therefore, the slope of the linear function → b(x) = f(x) - 30 is [m] = 10 and the [y] intercept is at [c] = - 30
