Answer:
y+1=7/13(x-6)
Step-by-step explanation:
the equation for point-slope form is y-y1=m(x-x1), where (x1,y1) is a point and m is the slope
first, we'll find the slope (m)
from two points, the slope is calculated as (y2-y1)/(x2-x1)
we're given (6,-1) and (-7,-8)
we can label the points
x1=6
y1=-1
x2=-7
y2=-8
now substitute into the formula
m=(-8--1)/(-7-6)
m=-7/-13
m=7/13
the slope (m) is 7/13
we already have labeled values for (x1,y1) which we made (6,-1)
substitute our known values into the equation
y--1=7/13(x-6)
simplify
y+1=7/13(x-6)

If f (-8)= 0 and f (x)= x^3-x^2-58x+112, find all the zeros of f(x) write your answer in ascending order
Answer:
The zeros in ascending order are 2, 7, 8.
Step-by-step explanation:
Since f(-8) = 0, it means that (x + 8) is a factor of the function f(x)= x³ - x² - 58x + 112.
I have attached the long division of this to get the remaining factors of the polynomial function.
The remaining factor is;
x² - 9x + 14
Using quadratic formula via a calculator, we have; x = 7 and x = 2
Thus,the zeros of the polynomial function f(x)= x³ - x² - 58x + 112 in ascending order are;
2, 7, 8
Write an equation in slope-intercept form for the line that passes through the
given point and is parallel to the graph of the given equation.
(4, -6), y=-3/4x+1
Answer:
[tex]y=-\frac{3}{4}x-3[/tex]
Step-by-step explanation:
The slope will be the same as the one in the given equation since they are parallel, you can substitute the x and y of the given point into the given equation, replacing the 1 with m to get m in the equation.
I hope this helps :)

The question is a model of rectangular stove top with four circular burners is shown the side length of the top stove and the diameter of the burners are labeled.which measurement is the best estimate of the area and square inches of the stove top that does not include the area of the burners?
Answer: see work
Step-by-step explanation:
Total area is 24x22=528
one circle area is (pi)3^2=9(pi)
that times 4 because of 4 circles =36(pi)
so the total are minus the circles now
in terms of pi the answer is 528-36(pi)
if pi = 3.14 the answer in 414.96
What would it be? thank you
Answer:
C = 43.98 inches; A = 153.94 square inches
Step-by-step explanation:
2*pi*(7)=43.98
pi*(7)^2=153.94
2. A store sells an assortment of batteries
in bulk packs of 300. Of those batteries.
90 are AAA size. What percent of the
pack are AAA-size batteries?
A 10%
B 30%
C 60
D 90
Answer quick PLZZ no website
Answer:
30%
Step-by-step explanation:
# of bulk packs = 300
# of triple As = 90
% = 90 / 300 * 100%
% = .3 * 100%
% = 30%
Answer:
b. 30%
Explanation:
90 ÷ 300 × 100%
= 9 ÷ 30 × 100%
= 0.3 × 100%
= 30%

Erik read a total of 4 books over 2 months. After belonging to the book club for 17 months, how many books will Erik have read in all? plss hep me thank you!!
Answer: 34 books
Step-by-step explanation:
Since Erik read a total of 4 books over 2 months. This means that every month, he read (4/2) = 2 books.
After belonging to the book club for 17 months, the number of books that he'll have read will be the number of books he read per month multiplied by 17 months. This will be:
= 2 × 17
= 34 books

Tell whether x and y show direct variation. Explain your reasoning.
(In your answer can u pls put like 19- 20- ty.)
Answer:
19 shows direct variation
20 does not (guessing for this one a bit)
19- Shows a steady increase of four in y for each one in x
20- Shows no increase
Step-by-step explanation:
19 is a constant increase by 4, 20 does not show either
- ZA and B are complementary angles. If mA = (x + 28)° and m ZB = (4x - 8), then find the measure of ZA.
Answer:
42 degrees
Step-by-step explanation:
"Complementary" means the angle measures add up to 90 degrees.
[tex]m\angle A+m\angle B =90^\circ\\(x+28)+(4x-8)=90\\5x+20=90\\5x=70\\x=14[/tex]
Now plug in 14 for x in the expression for the measure of angle A.
[tex]m\angle A = 14^\circ+28^\circ =42^\circ[/tex]

Given sin y = -4/5, where π < y < 3π/2, and cos x = 12/13, where 0 < x < π/2. Find the exact value of sin (x - y).
Please show all the exact steps in order I am really lost on how to solve this.
Answer:
Solution given:
sin y = -4/5
p/h=4/5
p=4
h=5
b=√{5²-4²)=3
cos y = b/h=-3/5
again
cos x=12/13
b/h=12/13
b=12
h=13
p=√(13²-12²)=5
sin x=p/h=5/13
now
sin[x-y]=sinxcosy-cosxsiny

In 2018 sienna invested 5000. The value of the invest,ent increases by 3%each year compounded weekly if she doesn't make additional transactions, what will be the value of her investment in 2025
Answer:
6168.02
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r/m)^mn
FV = Future value
P = Present value - 5000
R = interest rate = 0.03
N = number of years = 7
m = Number of compounding = 52
5000 x ( 1.000577)^52 x 7 = 6168.02
