Answer:
The correct option is;
10.25 + (-3.5) = 6.75
Step-by-step explanation:
We note that when adding numbers the negative sign is equivalent to the minus sign which is a mathematical operator. Therefore, when we subtract one number from another, it is equivalent to adding the negative of the other number to the first number
The given expression is 10.25 - (3.5)
The result of the given expression is 10.25 - (3.5) = 6.5
Therefore, we have;
10.25 + (-3.5) = 6.75

Write the equation in standard form for the circle that has a diameter with endpoints (22,0) and (2,0)
Answer:
(x - 12)² + y² = 100
Step-by-step explanation:
The standard form of the equation of a circle is;
(x - a)² + (y - b)² = r²
where:
a and b are the coordinates of the centre of the circle
r is the radius
We are given the coordinates of the endpoints of the diameter as; (22,0) and (2,0)
Thus, the centre of the circle would be at the mid point of the endpoints of the diameter.
Coordinates of the centre is;
((22 + 2)/2), (0 +0)/2))
This is;
(12, 0)
So, a = 12 and b = 0
Now,to get the radius r, we will use the formula;
r = √[(x2 - x1)² + (y2 - y1)²]
Where;
(x1, y1) and (x2, y2) are 2 points namely (12,0) and (22, 0)
r = √[(12 - 22)² + (0 - 0)²]
r = √(-10)²
r = √100
r = 10
Thus,equation of the circle is;
(x - 12)² + (y - 0)² = 10²
(x - 12)² + y² = 100

Which statement describes how the graph of a function, h(x), and its inverse, h‒1(x), are related? The line y = ‒x is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h‒1(x). The line y = x is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h‒1(x). The graph of the inverse of h(x) is a reflection over the line y = 0 of the graph of h(x). The y-axis is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h‒1(x).
Answer:
Option B.
Step-by-step explanation:
We know that, if the graph of a function is reflected across the line y=x, then we get the graph of inverse of that function.
It means, the graph of inverse function is the mirror image of graph of function across the line y=x.
If h(x) is a function and h⁻¹(x) is its inverse function, then the line y = x is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h⁻¹(x).
Therefore, the correct option is B.
Answer:
the answer is b

High interest rates make it difficult for people to pay off credit card debt in a reasonable period of time. The interest I (in dollars) paid on a $10,000 debt over 3 years when the interest rate is r% can be approximated by the equation shown below.†
I
175.393
+ 0.663 = r
If the credit card interest rate is 23.6%, find the amount of interest paid during the 3 years.
Answer:
Step-by-step explanation:
We are told that the equation is for a 3 year debt, which is also the period over which the . This means that we can use the equation.
(I/175.393) + 0.663 = r
We are given r = 23.6%
Plugging this vakue in for r gives;
l/175.393 + 0.663 = 23.6
l/175.393 = 23.6 - 0.663
l/175.393 = 22.937
I = 175.393 x 22.937
I = $4022.99, which is approximately

Anna was driving east on a freeway at a constant velocity. She was 570 kilometers west of
her exit. In 2 hours, she drove one-third of the way to her exit. What was her velocity?
Answer:
Her velocity is 95 km/hour
Step-by-step explanation:
The given information includes;
The direction to which Anna was driving = Eastward
Her initial location on the journey = 570 kilometres west of her her exit
The distance she drove in 2 hours = 1/3 of the way to her exit
Therefore, the distance she drove in 2 hours = 1/3×570 = 190 m
Her velocity = Her distance covered/(The time it take to cover the distance)
Which gives;
Her velocity = (190 km)/(2 hours) = 95 km/hour
Her velocity = 95 km/hour.

Write this equation in slope-intercept form (y = mx + b).
y-2=-3(x - 4)
Answer:
[tex]\huge\boxed{y=-3x+14}[/tex]
Step-by-step explanation:
[tex]y-2=-3(x-4)\\\\y-2=-3x+12\\\\y-2+2=-3x+12+2\\\\\boxed{y=-3x+14}[/tex]
First distribute the -3 through the parenthses
which gives us y - 2 = -3x + 12.
Move the number to the right side of the equation
by adding 2 to both sides to get y = -3x + 14.
Notice that the equation above is written in slope-intercept form because
the y term is isolated or by itself on the left side of the equation.

Answer:
[tex]y=\frac{3}{2}x+3[/tex]
Step-by-step explanation:
Take the given equation:
[tex]-3x+2y=6[/tex]
Solve for y so that the equation is written in slope-intercept form:
[tex]y=mx+b[/tex]
m is the slope and b is the y-intercept. x and y are the coordinate points (x,y).
Solve for y:
Add 3x to both sides of the equation:
[tex]-3x+3x+2y=6+3x\\\\2y=3x+6[/tex]
Divide both sides of the equation by 2 to isolate y:
[tex]\frac{2y}{2}=\frac{3x+6}{2} \\\\ y=\frac{3}{2}x+3[/tex]
The slope is [tex]\frac{3}{2}[/tex] and the y-intercept is 3.
To graph, you need two points. You can use the y-intercept as one.
The y-intercept is the place where the line crosses over the y-axis, where x equals 0, so the point is (0,3).
Next, take any value for x and insert it into the equation. We'll use 2:
[tex]y=\frac{3}{2}(2)+3[/tex]
Using this, you can solve for the value of y when x is equal to 2.
Simplify:
[tex]\frac{3}{2} *\frac{2}{1}=\frac{6}{2}=3 \\\\y=3+3\\\\y=6[/tex]
So, when x=2, y is 6 (2,6).
Plot the points (0,3) and (2,6)
Draw a straight line through the two, going past both.

Answer:
90
Step-by-step explanation:
Be sure to use PEMDAS. Begin with parentheses, the move to multiplication, then adding.
20 + 3(7 + 4) + 5 + 2(7+9)
20 + 3(11) + 5 + 2(16)
20 + 33 + 5 + 32
You can add those final four numbers in any order you want, to get a sum of 90.
Answer:
Your answer will be 90
Step-by-step explanation
First you will have to answer what's inside the parentheses
7 + 4 = 11 , 7 + 9 = 16
Then you multiply what is next to the parentheses
3×11 = 33, 2×16 = 32
Finally you will have to add
20 + 33 =53
53 + 5 =58
58 + 32 = 90

[tex]f(x) = - x^{2} - 7x - 5[/tex]
Find
[tex]f( - 5)[/tex]
===================================================
Explanation:
Everywhere you see an x, replace it with -5. Then use the order of operations PEMDAS to simplify
[tex]f(x) = -x^2 - 7x - 5\\\\f(-5) = -(-5)^2 - 7(-5) - 5\\\\f(-5) = -(25) - 7(-5) - 5\\\\f(-5) = -25 + 35 - 5\\\\f(-5) = 10 - 5\\\\f(-5) = 5\\\\[/tex]
Keep in mind that for the x^2 term, you are squaring all of x = -5, which includes the negative as well. So that means
x^2 = (-5)^2 = (-5)*(-5) = 25
but sticking a negative out front makes
-x^2 = -(-5)^2 = -25
Solve for x.
