Through (-3,-2), perpendicular to y=-x-4
Answer:
your answer is not perpendicular
Step-by-step explanation:
so first you put the y which is -2 and the -x with -3
[tex]-2=(-3)-4[/tex]
when you subtract the -3 from 4 you will get 7
[tex]4-(-3)=7[/tex]
7 is not equal to -2 so it is not perpendicular
[tex]7\neq -2[/tex]

2x+3y=9 and x-2y=8 system of equations
Answer:
(6, -1)
Step-by-step explanation:
Solve the System of Equations
2x + 3y = 9 and x − 2y = 8
Add 2y to both sides of the equation.
x = 8 + 2y 2x + 3y = 9
Replace all occurrences of x with 8 + 2y in each e quation.
Replace all occurrences of x in 2x + 3y = 9 with 8 + 2y. 2 (8 + 2y) + 3y = 9
x = 8 + 2y
Simplify 2 (8 + 2y) + 3y.
16 + 7y = 9
x = 8 + 2y
Solve for y in the first equation.
Move all terms not containing y to the right side of the equation.
7y = −7
x = 8 + 2y
Divide each term by 7 and simplify.
y = −1
x = 8 + 2y
Replace all occurrences of y with −1 in each equation.
Replace all occurrences of y in x = 8 + 2y with −1. x = 8 + 2 (−1)
y = −1
Simplify 8 + 2 (−1).
x = 6
y = −1
The solution to the system is the complete set of ordered pairs that are valid solutions.
(6, −1)
The result can be shown in multiple forms.
Point Form:
(6, −1)
Equation Form:
x = 6, y = −1

A survey of Ghasi's customers showed that 1,200 of the customers buying yarn would buy bamboo yarn. In the first month, 725 customers actually bought bamboo yarn. What was the percent error in the survey estimate of the number of people buying bamboo yarn? Round to the nearest tenth.
Answer:
40%Step-by-step explanation:
Step one:
given data
expected customers= 1200
actual customers= 725
the percent error= (actual-expected)/expected
substituting the given values we have'
%error=725-1200/1200
%error=475/1200
%error=0.395
To the nearest tenth we have 0.4
%error=0.4*100
%error=40%
Hence the percent error is 40%
Answer:
40%

Step-by-step explanation:
first: take 28 and divide it by 2 and you will get 14
now take 2 and divide it by 2 and you will get 1
now take the 14 put it over 1 like this------>14/1
Second:take the 5 and divide it by 2 and you get 2.5
not take the 2 and divide it by 2 and you get 1
now take 2.5 and put it over the 1 like this-------->2.5/1
third: take the 3 and divide it by 3/4

Two sides of a triangle are equal in length, and the third slide is 5 less than the length of the equal sides. If the perimeter of the triangle is 49, how long are it's sides?
Answer:
The sides are 14.6, 14.6, 9.6
Step-by-step explanation:
Step one:
given
Perimeter= 49
let the equal sides of the triangle be x
so the third side will be x-5
hence the first side is=x
the second side =x
and the third side=x-5
the perimeter of triangle is
P= A+B+C
where A B and C represents all the sides
49=x+x+(x-5)
solve for x
49=2x+x-5
49=3x-5
49-5=3x
44=3x
x=44/3
x=14.6
Hence the third side is
=x-5=14.6-5
=9.6
The sides are 14.6, 14.6, 9.6

Carlos bought 4 yards of packing tape. He used 1 3/5 yards on a package for his father and 2 1/3 for a package. How many yards of packing tape does Carlos have left (only write the fraction with no words as your answer)?
Answer:
1/15 yards
Step-by-step explanation:
Total yards of packing tape = 4 yards
Yards used for his father = 1 3/5 yards
Yards used for another package = 2 1/3 yards
Total yards used = 1 3/5 + 2 1/3
= 8/5 + 7/3
= 24+35/15
= 59/15 yards
How many yards of packing tape does Carlos have left
Total yards left = Total yards of packing tape - Total yards used
= 4 - 59/15
= 60-59/15
= 1/15
Total yards left = 1/15 yards

Your buddy constructs an angle bisector BD−→− for ∠ABC. She says that m∡ABD and m∡DBC formed by the angle bisector are congruent. Do you think that is always, sometimes or never true for angle bisectors?
Answer:
Always true
Step-by-step explanation:
The definition of an interior or internal angle bisector is the the dividing line segment that splits the angle into two equal angles (parts)
Therefore, given that the segment BD is the bisector of ∠ABC, then the formed angles m∡ABD and m∡DBC are, by definition of bisected ∠ABC, always congruent

Answer:
- 2x² + x + 42x² + x + 43Step-by-step explanation:
Given functions
r(x) = x + 4s(x) = 2x²Finding (r-s)(x), (r+s)(x), (r*s)(-1)
(r - s)(x) = r(x) - s(x) = x + 4 - 2x² = - 2x² + x + 4(r + s)(x) = r(x) + s(x) = x + 4 + 2x² = 2x² + x + 4(r*s)(-1) = r(-1)*s(-1) = (-1 + 4)*(-1)² = 3*1 = 3Answer:
1. - 2x² + x + 4
2. 2x² + x + 4
3. Answer = 3
Example functions we are given:
r(x) = x + 4
s(x) = 2x²
Now, we Find (r-s)(x), (r+s)(x), (r*s)(-1)
(r - s)(x) = r(x) - s(x) = x + 4 - 2x² = - 2x² + x + 4
(r + s)(x) = r(x) + s(x) = x + 4 + 2x² = 2x² + x + 4
(r*s)(-1) = r(-1)*s(-1) = (-1 + 4)*(-1)² = 3*1 = 3
Leslie and Surekha were standing on opposite sides of a road. Suddenly, they spotted a puppy stranded on the road and both rushed straight to where the puppy was, to pick it up. If Leslie ran at an angle of 35 degrees to the edge of the road and Surekha at an angle of 70 degrees, at what angle did their path meet?
Answer:
75°
Step-by-step explanation:
we can form a triangle to help us understand how to solve this problem:
puppy
∠ Leslie = 35° ∠ Surekha = 70°
If Leslie's angle is 35° and Surekha's angle is 70°, that gives us a total of 105°. Since the sum of the triangle's three angles is 180°, then the angle at which they will meet is 180° - 105° = 75°
In this exercise, we have to calculate the angle of the path that they met, so we will have:
75°
We know that the geometric figure in question is a triangle and that the sum of its internal angles must be equal to 180 degrees, thus:
[tex]180-105=X\\180-105=75\\[/tex]

D. 2,515 inches
(SHOW YOUR WORK FOR A BRAINLIEST)
Answer:
C
Step-by-step explanation:
Answer:
B. 2,324 inches
Step-by-step explanation:
You need to find the circumference of the bike wheels first so that you know how much she would travel if her wheels rotated 1 time. Circumference of circle = pi × d
1 time = 20pi
37 times = 20pi × 37
= 740pi
= 2324.778564...inches
The diameter of a cartwheel is 2.1 m. Find the distance travelled when it completes 100 revolutions.
You need to find the circumference of the cartwheels first so that you know how much it would travel if her wheels revoluted 1 time. Circumference of circle = pi × d
1 revolution = 2.1pi
100 revolutions = 2.1pi × 100
= 210pi
= 659.7344573...m
The diameter of a circular park is 98 m. Find the cost of fencing it at $4 per meter.
You need to find the circumference of the park first so that you know how much it would cost. Circumference of circle = pi × d
Circumference of park = 98pi
Cost of fencing = 4 × 98pi
= 392pi
= $1231.50
≈ $1232.00

Which scenarios represent one quantity changing at a constant rate per unit interval relative to the other quantity?
Select all that apply
A. An employee earns $14 per hour.
B. An employee earns a 3% raise each year.
C. A gym charges a $50 down payment plus $30 per month.
D. A piece of gym equipment decreases 8% in value every 6 months.
E. A trainer charges $20 for every 30 minutes of training plus a $5 tip.
Answer:C and E
Step-by-step explanation:
An employee earns $14 per hour and a trainer charges $20 for every 30 minutes of training plus a $5 tip are a constant rate per unit interval. Therefore, options A and E are the correct answers.
Given that, an employee earns $14 per hour.
What is constant rate of change?When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.
A). Let the number of hours be x and the total money earned be y
So, y=14x
B). Let the money earn by an employee each year be a and total earning in a year be b.
So, b=a+3% of a
⇒ b=a+0.03a
⇒ b=1.03a
C) Let the number of months be m and the total charge be t
So, t=50+30m
D) Let cost of gym equipment be p, rate of change =8% and time period = 6 months
So, [tex]A=p(1-\frac{8}{100} )^{6t}=p(0.92)^{6t}[/tex]
E) Let the number of hour be x.
Here, 30 minutes = 1/2 hours
Total charge = 20+5x/2
An employee earns $14 per hour and a trainer charges $20 for every 30 minutes of training plus a $5 tip are a constant rate per unit interval. Therefore, options A and E are the correct answers.
