In triangle ABC, EP=4. What is PC?
Answer:
PC = 8
Step-by-step explanation:
BF and CE are medians of the triangle.
On each median the distance from the vertex to the centroid P is twice as long as the distance from the centroid to the midpoint, then
PC = 2 × EP = 2 × 4 = 8

1. Which of the following is NOT a possibility
for a system of two linear equations?
a. having no solution
b. having one solution
c. having two solutions
d. having infinitely many solutions
Answer:
c. having two solutions
Answer:
C because for there to be two solutions, one or more of the lines graphed would have to be curved, meaning having two solutions is not possible for two linear equations

A and B can do a task in t hours.A and b can complete the task in t+2 and t+18 hours respectively.Find t
Step-by-step explanation:
A can do 1/(t+2) of the task in 1 hour.
B can do 1/(t+18) of the task in 1 hour.
t×1/(t+2) + t×1/(t+18) = t/t = 1 (the full task is done)
t + t×(t+2)/(t+18) = t+2
t×(t+18) + t×(t+2) = (t+2)(t+18)
t² + 18t + t² + 2t = t² + 20t + 36
2t² + 20t = t² + 20t + 36
2t² = t² + 36
t² = 36
t = 6

Which list of points are solutions to the graph of y = 1/2x - 2
Answer:
B) (20,8) , (30,13) , (40,18)
Step-by-step explanation:
To check: (20,8)
y = 1/2x - 2
8 = 1/2(20) - 2
8 = 10 - 2
8 = 8
This is true, which makes our point true.
To check: (30,13)
y = 1/2x - 2
13 = 1/2(30) - 2
13 = 15 - 2
13 = 13
This is true, which makes our point true.
To check: (40,18)
y = 1/2x - 2
18 = 1/2(40) - 2
18 = 20 - 2
18 = 18
This is true, which makes our point true.
Hope that helps!
ect the best answer for the question.
What is the slope of a line that passes through (-12,15) and (0,4)?
Answer:
y = -11/12x + 4
Step-by-step explanation:
(-12,15) and (0.4)
4 - 15 = -11
0 -(-12) = 12 (since minus a negative = positive)
-11/12
Then just put the numbers.
15 = -11/12(-12)
15 = 11 + b
4 = b

Slopes are really fun to do, but they get tricky and confusing. By the way, I am 14 years old and I did slopes, and I'm not the best at this, so I might be wrong. :( Don't hate me.
Answer:
-11/12
Step-by-step explanation:
The slope of the line is the difference in y-values divided by the difference in x-values. It is ...
m = (y2 -y1)/(x2 -x1)
m = (4 -15)/(0 -(-12)) = -11/12
The slope of the line through the given points is -11/12.

Can y’all please help me with this question . I need the answer ASAP!!
Answer: This is the answer to your equation sorry I had to do It on a doc
Answer:
-4
-4
1
-8
1
Step-by-step explanation:
[tex]x^2-4x-8=0[/tex]
Comparing [tex]ax^2+bx+c=0[/tex]
⇒ a = 1, b = -4 and c = -8
Substituting these values into the quadratic formula:
[tex]x=\frac{-(-4)\pm\sqrt{(-4)^2-4(1)(-8)} }{2(1)}[/tex]
(The numbers you need to fill in the blanks are in bracket)
A car travels 10 km southeast and
then 15 km in a direction 60° north of
east. Find the magnitude of the car's
resultant vector.
[?] km
Round to the nearest tenth.
[tex]\bold{\huge{\green{\underline{Solution}}}}[/tex]
A car travels 10 km southeast and then 15 km in a direction 60° north of east[tex]\bold{\underline{ To\: Find }}[/tex]
We have to find the magnitude of the car of resultant vector[tex]\bold{\underline{ Let's \: Begin }}[/tex]
Here,
In South east, car travels = 10kmIn North of east, it travels = 15kmAngle between south east and north east is 60°Therefore,
According to parallelogram law of resultant vector
If two vectors are represented by two adjacent sides of a parallelogram drawn from a point , the their resultant is equal to the diagonal of the parallelogram.
That is,
[tex]\sf{ R = AC^{2}= A^{2}+ B^{2}}[/tex]
But, we have to calculate the magnitude of the resultant vector
[tex]\sf{ | R |= √A^{2}+ B^{2}+ 2ABCos{\theta} }[/tex]
Subsitute the required values,
[tex]\sf{ | R |=\sqrt{ (10)^{2} + (15)^{2} + 2× 10 × 15 × cos 60{\degree}}}[/tex]
[tex]\sf{ | R | =\sqrt{ 100 + 225 + 20 × 15 × 1/2}}[/tex]
[tex]\sf{ | R | = \sqrt{100 + 225 + 10 × 15 }}[/tex]
[tex]\sf{ | R | = \sqrt{335 + 150 }}[/tex]
[tex]\sf{ | R | = \sqrt{485 }}[/tex]
[tex]\sf{\red{ | R | = 22.02 \: km}}[/tex]
Hence, The magnitude of the car resultant vector is 22.02 km.

There are three different companies that are willing to provide the hot dogs.
• Company A charges $15 toevery 25 hot dogs, plus a cooking fee of $65.
• Company B charges $7 for every 14 hot dogs, plus a cooking fee of $62.
• Company C charges $22 for every 50 hot dogs, plus a cooking fee of $57.
Based on the number of hot dogs needed in question 5, what company will charge you the least amount of money? How do you know?
Answer:
Company A makes more for one purchase, and Company B makes more for ten purchases. Company C makes less for one purchase and Company A makes less for ten purchases.
Step-by-step explanation:
Company A: y = -3/5x + 65
Company B: y=1/2x + 62
Company C: 11/25x + 57
Make sure x is 1 then do all the equations, then x is 10 and do all the equations to see which has more amount of money and which has less.
Company A: 64.4 (if x = 1)
Company B: 62.5 (if x = 1)
Company C: 57.44 (if x = 1)
if x = 10
Company A: 59
Company B: 67
Company C: 61.4
(I might be wrong since I'm 14)
Company A makes more for one purchase, and Company B makes more for ten purchases. Company C makes less for one purchase and Company A makes less for ten purchases.

Answer:
y=6x-4
Step-by-step explanation:
First find the slope using the coordinates of (-1,-10) which will be your first pair x1 and y1. And (3,14) will be x2 and y2. To find the slope use this formula: m= y2-y1/x2-x1
Put the numbers of the coordinates in the formula and you get a fraction of
24/4 = 6 this is the slope
m=6
Then to find the y-int
Pick a coordinate they both will give the same answer. Put it into the point slope formula: y-y1=m(x-x1)
Only use y1, x1, and m which is 6 And solve
y-14=6(x-3) distribute the 6 this gives you
y-14=6x-18 to get y by itself, ADD 14 to both sides of the equal sign
Leaving you with y=6x-4
Tesa and Vivienne share £96 in the ratio 5:3. How much does Tesa receive?
Answer:
Tessa receives £60
Step-by-step explanation:
The ratio is 5:3 so 5+3=8 which is then what you use to divide 96
96/8=12
12x5(the 5 comes from the ratio for Tess) is 60 therefore she receives £60
Answer:
60£Step-by-step explanation:
Tesa and Vivienne share £96 in the ratio 5:3. How much does Tesa receive?
96 : (5 + 3) = 12
12 * 5 = 60
