Answer:
slope: 6; y-intercept: -8
Step-by-step explanation:
The given equation is :
y + 8 = 6x
The general equation of a line is :
y = mx+b...(1)
Where
m is slope and b is y-intercept
Equation (1) can be rewritten as follows :
y = 6x -8
or
y = 6x +(-8) ....(2)
Compare equation (1) and (2) we get :
Slope, m = 6 and y intercept = -8
Hence, the correct option is (c).

Written as a simplified polynomial in standard form, what is
the result when (2x – 5)2 is subtracted from x-10?
Answer:
[tex]\left(x-10\right)-\left(2x-5\right)^2=-4x^2+21x-35[/tex]
Step-by-step explanation:
As we have to subtract [tex]\left(2x\:-\:5\right)^2[/tex] from [tex]\left(x-10\right)[/tex]
so
[tex]\left(x-10\right)-\left(2x\:-\:5\right)^2[/tex]
solving and simplifying the polynomial in standard form
[tex]\left(x-10\right)-\left(2x-5\right)^2[/tex]
[tex]\mathrm{Remove\:parentheses}:\quad \left(a\right)=a[/tex]
[tex]=x-10-\left(2x-5\right)^2[/tex]
[tex]=x-10-\left(4x^2-20x+25\right)[/tex] ∵ [tex]\left(2x\:-\:5\right)^2=\:4x^2-20x+25[/tex]
[tex]=x-10-4x^2+20x-25[/tex]
[tex]=-4x^2+21x-35[/tex]
We know that standard form means that the terms of the expression are ordered from biggest exponent to lowest exponent.
Thus, a simplified polynomial in standard form is:
[tex]\left(x-10\right)-\left(2x-5\right)^2=-4x^2+21x-35[/tex]
What number would you multiply the 2nd equation by in order to eliminate the y terms?
4x - 4y = 16
2x + y = 5
Answer:
x=3
y=-1
Step-by-step explanation:
first multiply the 2nd row by 2 so you will get
4x-4y=16
4x+2y=10
then subtract the 2nd row from the first row and so you will get
-6y=6
then solve for y in the above equation
y=-1
then substitute y=-1 into any 2 equations .
i picked the first 1
4x-4 × -1=16
then solve for x .
you will get
x=3
t to the second power - 12w ÷ x
t=8
w=1/2
x=3
Answer:
62
Step-by-step explanation:
Since we know what each value of the three variables are, you can substitute each variable in the expression to get:
[tex]8^{2} -12(\frac{1}{2})[/tex] ÷ 3
Simplify to get:
64 - 6 ÷ 3
Solve the rest:
64 - 2 → 62
Answer: 62

The question of the pic was cut off at the top and it says -
Line W is graphed on the coordinates plane below.
Answer: A
Explanation:
Step 1: Use the linear graph to create an equation using slope-intercept form. The y-intercept is (0,-6) because that's where the line passes the y-axis. The slope is 1/2 and that's pretty self-explanatory if you know how to find slope. The equation would be y=1/2x-6.
Step 2: Because we are looking for a line perpendicular to the linear graph, the y-intercept and slope needs to be different. If they're perpendicular, they need to intersect, so the slope needs to be the reciprocal of the original slope, 1/2. The reciprocal is -2. Your equation would be y=-2x+b, and since we don't know the y-intercept, we would leave it as b.
Step 3: Plug in the given ordered pair, (-3,-2), to get -2=-2(-3)+b. You would result with -2=6+b. Subtract 6 to both sides and you would get b=-8.

The cost C, in dollars, to have medical records transcribed is a function of time, t in hours. A physician's group spends C(t) = 0.04t3 – 0.1t2 + 5.5t dollars to transcribe the physician's. Notes to an electronic document each month. What is the instantaneous rate of change when the transcriptionist has spent 100 hours transcribing records? A) $118.50 B)$395.50 C)$1,185.50 D)$1,195.50
Answer:
B. $39550
Step-by-step explanation:
The expression for the function is not well-formatted, find the correct format in the solution bellow
Step one:
given data
We are told that the function of the cost is
[tex]C(t) = 0.04t^3- 0.1t^2 + 5.5t[/tex]
instantaneous rate c(t) is the value obtained when we plug in 100 for t in the function above
substituting we have
[tex]C(t) = 0.04(100)^3- 0.1(100)^2 + 5.5(100)\\\\\C(t) = 0.04*1000000- 0.1*10000 + 5.5*100\\\\C(t) = 40000-1000+550\\\\C(t) = 39550[/tex]

The altitude of Object B is 27 times the altitude of Object A. The altitude of Object A is $3^3$ feet. What is the altitude of Object B? Write your answer as a power.
ft
Answer:
3^6
Step-by-step explanation:
We know that A is 3^3 and B is 27 times that.
3•3•3=27
So B is 3•3•3• of 3^3 which is 3•3•3•3•3•3
Write the answer to the exponents which will be 3^6
A) Find the distance of line segment PR. Round answer to the nearest tenth. B) Find the distance around the park (perimeter).
Answer:
A. [tex] PR = 80.6 yd [/tex]
B. Perimeter = 190.6 yd
Step-by-step explanation:
A. Distance between P(10, 50) and R(80, 10):
[tex] PR = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
[tex] PR = \sqrt{(80 - 10)^2 + (10 - 50)^2} [/tex]
[tex] PR = \sqrt{(70)^2 + (-40)^2} [/tex]
[tex] PR = \sqrt{4,900 + 1,600} [/tex]
[tex] PR = \sqrt{6,500} [/tex]
[tex] PR = 80.6 yd [/tex] (nearest tenth)
B. Distance around the park = Perimeter = PR + PQ + QR
PR = 80.6 yd
PQ = |50 - 10| = 40 yd
QR = |80 - 10| = 70 yd
Perimeter = 80.6 + 40 + 70
Perimeter = 190.6 yd
