Step-by-step explanation:
In the diagram shown, C is the midpoint of BD. What is the
length of AC?
Set up an equation based on the given information, solve
for x, and plug answer back in to answer the question
Answer:
AC = 20
Step-by-step explanation:
C is the midpoint of BD.
That means that BC = CD
BC = x + 4
CD = 3x - 10
x + 4 = 3x - 10 Subtract x from both sides
4 = 3x - x - 10 Combine
4 = 2x - 10 Add 10 to both sides
4 + 10 = 2x - 10 + 10 Combine
14 = 2x Divide by 2
14/2 = 2x/2 Combine
7 = x
AC = AB + BC
AC = 2x - 5 + x + 4
AC = 3x - 1
AC = 3*7 - 1
AC = 21 - 1
AC = 20

Find the gradient of the line
3y + 2x = 1
how to guys
Answer:
-2/3
Step-by-step explanation:
The gradient of a line is its slope. You can just convert the equation to slope-intercept form (y=mx+b where "m" is the gradient/slope):
3y + 2x = 1
3y = 1 - 2x
y = 1/3 - 2/3x
y = -2/3x + 1/3
So, as we can see, -2/3 is the gradient/slope of the line.

The length of a rectangle is one more than twice its width. If the perimeter of the rectangle is 134
centimeters, find its length.
Answer: We can set up the formula: 2L +2W = 110. We can also set up length as 2x+1 and width as x so plug this in: 2 (2x+1)+2x=110. Expanded to: 4x+2+2x=110. Rewritten as: 6x=108.

Find the graphed solution to the inequality. 3(x-9) < -18
Closed or open, left or right?
Answer:
open left
Step-by-step explanation:
We can distribute the left side to get [tex]3x-27<-18[/tex].
We can then add [tex]27[/tex] to both sides of the equation to get [tex]3x<9[/tex].
We can finally divide both sides of the equation to get [tex]x<3[/tex].
Because it's a [tex]<[/tex] and not a [tex]<=[/tex], it is closed. And because the inequality opens to the right, it faces to the left.
So, it is a open left graph.

Ahmed bought 5 equally priced markers for $3.25.
How much will 12 of these markers cost?
$1.35
$6.68
$7.80
$8.46
Answer:
$7.80
Step-by-step explanation:
Find the unit price by dividing 3.25 by 5.
3.25 ÷ 5 = 0.65
Now that you have the unit price, multiply it by 12 to find the total price of the 12 markers.
0.65 × 12 = 7.80
Thus, 12 of the same markers that Ahmed bought will cost $7.80.
The cost of 12 markers is given by the equation A = $ 7.80
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the number of markers be n = 5
The cost of 5 markers = $ 3.25
So , the cost of 1 marker = cost of 5 markers / 5
On simplifying the equation , we get
The cost of 1 marker = 3.25 / 5
The cost of 1 marker = $ 0.65
Now , the cost of 12 markers = 12 x cost of 1 marker
Substituting the values in the equation , we get
The cost of 12 markers A = 12 x $ 0.65
The cost of 12 markers A = $ 7.80
Hence , the equation is A = $ 7.80 , where A is the total cost of markers

Calculus, derivatives. Please help! Show work, if possible. Thanks! :)
Answer:
a. y=4
b. graph the given and y=4
Step-by-step explanation:
The given is y= 8 sin(x) cos(x)
to get y' which is the slope of the tangent line we take the derivative
for this problem, the derivative involves the constant rule (which states that the derivative a constant times a value is just the constant times the derivative of said value) and the multiplication rule (assuming that the two parts in question are represented by the variables a and b then the derivative of a*b = a*b'+b*a')
thus we get 8*(sin(x)*-sin(x)+cos(x)*cos(x))
-8sin^2(x)+8cos^2(x)
You can also leave the 8 differentiated out depending on the form you need.
Now that we have the derivative we can plug pi/4 into this equation to get the slope of the tangent line at that point
=8sin^2(pi/4)+8cos^2(pi/4)
this would equal -8*1/2 +8*1/2 which equals 0
the slope of the tangent at this point would be zero
To get the point for point slope form we plug the pi/4 into the given equation to get a y value and get the point (pi/4, 4)
this means the point slope equation would be
y-4=0(x-pi/4)
y-4=0
y=4
To graph you would just enter the given equation and the equation for the tangent line into a graphing software or calculator and see if the line is tangent at the point (pi/4, 4)
