Answer:
y=-8/7x-4
from, m1m2=-1
-8/7m2=-1
m2=7/8
again from, m=(y-y1)/(x-x1)
7/8=(y-9)/(x-10)
8(y-9)=7(x-10)
8y-72=7x-70
8y=7x-70+72
8y=7x+2
therefere,
y=7/8x+1/4

Before a school election, a sample of voters gave Karim 28 votes, Marisol 41, and Richard 11. Based on these results, predict the number of votes for Karim if 1600 vote.
Answer:
560 votes
Step-by-step explanation:
Given that :
Sample votes :
Karim 28 votes ;Marisol 41 ; and Richard 11
Total sample votes = 28 + 41 + 11 = 80
Percentage vote obtained by Karim :
(28 / 80) * 100%
0.35 * 100%
35% of sample votes
Prediction if votes were 1600;
35% of 1600
0.35 * 1600
= 560 votes
Determine whether each point lies on the circle. Then use symmetry to determine another point on the circle.
Circle K has its center at (0,0) and a radius of 4.
Point N is at (3, square root of 7).
Plz help! I'll give Brainliest!!
Given:
Circle K has its center at (0,0) and a radius of 4.
Point N is at [tex](3,\sqrt{7})[/tex].
To find:
To check whether the point N lies on the circle or not. Then find the other point using symmetry.
Solution:
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex] ...(i)
where, (h,k) is center and r is radius.
Circle K has its center at (0,0) and a radius of 4. Putting h=0, k=0 and r= 4 in (i), to get the equation of circle K.
[tex](x-0)^2+(y-0)^2=4^2[/tex]
[tex]x^2+y^2=16[/tex] ...(ii)
To check the point [tex]N(3,\sqrt{7})[/tex], put x=3 and [tex]y=\sqrt{7}[/tex] in (ii).
[tex](3)^2+(\sqrt{7})^2=16[/tex]
[tex]9+7=16[/tex]
[tex]16=16[/tex]
This statement is true. So. option [tex]N(3,\sqrt{7})[/tex] lies on the circle K.
According to the symmetry about the origin, if (x,y) lies on the graph then (-x,-y) also lies on that graph.
Since the center of the circle is origin, therefore, it is symmetrical about the origin.
Thus, point [tex]P(-3,-\sqrt{7})[/tex] must be on the circle K.
Therefore, the another point on the circle K is [tex]P(-3,-\sqrt{7})[/tex].

the duration of a flash from a camera is timed at 0.004 seconds accurate to 1 / 1000 of a second calculate the upper and lower bounds for the duration of the flash using in quality
Answer:
0.0035 ≤ x ≤ 0.0045
Step-by-step explanation:
Given that:
The error = 1/1000 = 0.001 / 2 = 0.0005 s
Hence, 0.004 ± Error
0.004 ± 0.0005
Lower boundary = (0.004 - 0.001) = 0.0035
Upper boundary = (0.004 + 0.001) = 0.0045
0.0035 ≤ x ≤ 0.0045

Select all of the equations that have graphs with the same y-intercept (starting amount).
Answer: y=3x-8, y=5x-8, and y=2x-8
Step-by-step explanation:
These equations are all lines in slope-intercept form (y=mx+b where b is the y-intercept). y=3x-8, y=5x-8, and y=2x-8 all have -8 as the b value. Therefore, these equations have the same y-intercept.

Answer:
60
Step-by-step explanation:
There were 160 votes in total, and we need to figure out how much is 3/8 of it. Therefore, we need to find (3/8)*(160) (of is another word for multiply). The easiest method is to find 1/8 of 160 which is 20, and then multiply it by three to get 60, which is your answer!

write an equation for a line parallel to y=-2x-1 that passes through (2,-7)
Answer:
The equation is;
y = -2x - 3
Step-by-step explanation:
If two lines are parallel, then they have an equal value of slope
Mathematically we can generally have the equation of a line written as;
y = mx + c
where m
is slope and c is the y-intercept
In the case of the equation given, the slope of the line is -2
So technically, we want to get the equation of a line that has a slope of -2 and it passes through (2,-7)
The point-slope form can be written as;
y-y1 = m(x-x1)
So the equation we want to get is;
y-(-7) = -2(x-2)
y + 7 = -2x + 4
y = -2x + 4 - 7
y = -2x - 3

It takes 91 pounds of seed to completely plant a 10-acre field. How many acres can be planted per pound of seed?
Answer:
[tex]0.109\ \text{acres per pound}[/tex]
Step-by-step explanation:
Given that,
It takes 91 pounds of seed to completely plant a 10-acre field.
We need to find how many acres can be planted per pound of seed. Let it is x. It can be calculated by dividing acres to pounds per seeds.
[tex]x=\dfrac{10}{91}\\\\=0.109\ \text{acres per pound}[/tex]
So, the required answer is [tex]0.109\ \text{acres per pound}[/tex].
A cube has a volume of 64 cubic meters what is the length of each edge
Answer:
The length of each side is 4 m
Step-by-step explanation:
The volume of a cube is given by
V = s^3 where s is the side length
64 = s^3
Take the cube root of each side
64 ^ (1/3) = s^3 ^ (1/3)
4 = s
The length of each side is 4 m
Answer: 4 cubic meters
Step-by-step explanation:
The volume of a cube = a³
4³ = 64
So the length of each length has to be 4 cubic meters.

The answer is below
Step-by-step explanation:
a) g(10) = -3(10) + 1 = -30 + 1 = -29
b) f(3) = (3)² + 7 = 16
c) h(-2) = 12 / (-2) = -6
d) j(7) = 2(7) + 9 = 14 + 9 = 23
e) h(a) = 12 / (a) = 12 / a
f) g(b + c) = -3(b + c) + 1 = 1 - 3b - 3c
h) g(x) = 16
-3x + 1 = 16
3x = 1 - 16
3x = -15
x = -5
i) h(x) = -2
12 / x = -2
x = 12 / -2 = -6
j) f(x) = 23
23 = x² + 7
x² = 16
x = √16
x = 4

Trevor measured the town library and made a scale drawing. In real life, the parking lot is 75 meters long. It is 135 centimeters long in the drawing. What scale did Trevor use? 9 centimeters : meters
Answer: [tex]9\ cm\equiv 5\ m[/tex]
Step-by-step explanation:
Given
The actual length of the parking lot is 75 m
length in the drawing is 135 cm
Here, 75 m is equivalent to 135 cm
Using unitary method
[tex]75\ m\equiv 135\ cm[/tex]
[tex]15\ m\equiv 27\ cm[/tex]
[tex]9\ cm\equiv \frac{15}{3}=5\ \text{m}[/tex]
The sum of the measures of angle A and angle B is 90 degrees. The measure of angle A is (5x + 10) The measure of angle B is 3x degrees
Answer:
m<A is 60 degrees
m<B is 30 degrees
Step-by-step explanation:
As the problem says, the sum of m<A and m<B=90 degrees (m<A+m<B=90). The given measures are (5x+10) for <A and 3x for <B
we can substitute (5x+10) and 3x as <A and <B into the equation
so:
5x+10+3x=90
Combine like terms
8x+10=90
subtract 10 from both sides
8x=80
divide by 8
x=10
Now substitute as x
m<A: (5*10+10)=50+10=60 degrees
m<B: (3*10)=30 degrees
Hope this helps!
