1008
Step-by-step explanation:
geometric sequence:
a=16
r=32/16=2
Sum of GS:
s=a(1-r^n)/(1-r)
S(6)=16(1-2^6)/(1-2)

Slope intercept form
Given:
The equation of the parallel line is
[tex]y=-\dfrac{5}{2}x+7[/tex]
The required line passes through the point (-4,1).
To find:
The equation of line in slope slope intercept form.
Solution:
The slope intercept form of a linear function is
[tex]y=mx+b[/tex]
Where m is slope and b is y-intercept.
On comparing the equation [tex]y=-\dfrac{5}{2}x+7[/tex] with slope intercept form, we get
[tex]m=-\dfrac{5}{2}[/tex]
We know that the slopes of parallel lines are always same. So, the slope of the required line is [tex]m=-\dfrac{5}{2}[/tex].
The line passes through the point (-4,1) with slope [tex]m=-\dfrac{5}{2}[/tex]. So, the equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-(1)=-\dfrac{5}{2}(x-(-4))[/tex]
[tex]y-1=-\dfrac{5}{2}(x+4)[/tex]
[tex]y-1=-\dfrac{5}{2}x-10[/tex]
Adding 1 on both sides, we get
[tex]y=-\dfrac{5}{2}x-10+1[/tex]
[tex]y=-\dfrac{5}{2}x-9[/tex]
Therefore, the correct option is C.

The next model of a sports car will cost 12.2% less than the current model. The current model costs $34,000 . How much will the price decrease in dollars? What will be the price of the next model?
Answer:
Price decrease in dollars = $4,148Price of next model = $29,852Step-by-step explanation:
The next car will be 12.2% cheaper. This amount in dollars is:
= Percentage decrease * Current model price
= 12.2% * 34,000
= $4,148
The price of the next model will therefore be:
= 34,000 - 4,148
= $29,852
plese help with both of these
Answer:
Step-by-step explanation:
Explicit formula of a G.P. is given by,
[tex]a_n=a(r)^{n-1}[/tex]
Here, [tex]a_n[/tex] = nth term
a = First term
n = number of term
r = common ratio
Given sequence is 3, 6, 12, .......
a = 3
r = [tex]\frac{6}{3}[/tex] = 2
Therefore, explicit formula will be,
[tex]a_n=3(2)^{n-1}[/tex]
Option (3) is the answer.
Parent function → f(x) = 3ˣ
Transformed function → g(x) = [tex]3^{x+5}[/tex]
Since, g(x) = f(x + 5)
Therefore, function 'f' has been shifted 5 units left.
Option (1) is the answer.

math please help ! <<
Answer:
d = - 6
a = - 20
T(n) = a + (n - 1)d
= -20 + (n - 1 )(-6)
= -20 - 6n + 6
= -14 - 6n
= -2(7 + 3n)
-20 -6(n-1) answer
Find the equation of the line given the two points below
A(−3,−2) B(6,−8)
Answer:
y = -2/3x - 4
Step-by-step explanation:
Formula: y = mx + b
m (slope)
b (y-intercept)
Slope Formula: y2 - y1 ÷ x2 - x1
Substitute: -8-(-2) = -8+2 = -6
6-(-3) = 6+3 = 9
-6/9 (funny, I know)
Simplify --> -2/3
slope = -2/3
Substitute for the y-intercept --> to do this, we plug in a coordinate pair
-8 = -2/3(6) + b
-8 = -4 + b => add 4 to both sides
b = -4, and thus, our y-intercept is -4
Plug our values into the formula: y = mx + b
y = -2/3x + (-4)
simplify to get our final equation
y = -2/3x - 4

SHOW YOUR WORK WILL MARK BRAINLIEST IF YOU GET IT RIGHT solve by completing the square X²+6x-22=0
9514 1404 393
Answer:
x = -3±√31 ≈ {-8.568, +2.568}
Step-by-step explanation:
The usual steps are to ...
group the x-terms
(x² +6x) -22 = 0
add and subtract the square of half the x-coefficient
(x² +6x +(6/2)²) -22 -(6/2)² = 0
simplify to a binomial square
(x +3)² -31 = 0
Solve for x.
(x +3)² = 31
x +3 = ±√31
x = -3 ±√31 . . . . . solution to the quadratic
