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]

A spinner has five section labeled ABC D & E the spinner is spun 45 times in there so I recorded in the table what is the experimental probability of the spinner landing on see round to the nearest percent and if necessary
Answer:
It'll be 18% to the nearest percent
Step-by-step explanation:
2/5 × 45 = 18
Answer:
The answer is 18%
Step-by-step explanation:
The formula to find experimental probability is number of favorable outcomes/total number of trails. Our favorable outcome here is C ( the outcome we want), and it occurs 8 times. The spinner is spun 45 times so there are 45 trials. This means we get 8/45. 8 divided by 45 equals 0.177777778. When rounded up equals 0.18=18%.

-3х + 2 = 2х - 8
Solve for X
Answer:
x=2
Step-by-step explanation:
you would add -3x on both sides, then that cancels out, and then the equation would be 2=5x-8. Then you would add 8 to both sides then it would be 10=5x. Then you would divide 5 by both sides, then it will be x=2.

WORK The ecology club is landscaping a local park. Dell can plant a flower bed in 3 hours. Max can plant a flower bed of the same size in 4 hours. a. Using t, time in hours, write an expression representing how many flower beds they will complete in t hours working together.
Step-by-step explanation:
this simply means that Dell can do 1/3 of the work in 1 hour, and Max can do 1/4 of the work in 1 hour.
so, working together, they can complete 1/3 + 1/4 of the work in 1 hour.
to really add these fractions, we need to bring them to the same denominator by finding the smallest (or lowest) common multiple of the existing denominators, which is in this very simple case just 3×4 = 12
1/3 + 1/4 = 4/12 + 3/12 = 7/12
therefore, together they can complete 7/12 of a flower bed in 1 hour.
so, by defining the variable fb as the number of completed flower beds :
fb = 7/12 × t

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
Additional Information:
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.

A father is 3 times as old as his son, 9 years ago the father was 4 times as old
as his son. find their present ages.
[tex]\bold{\huge{\green{\underline{ Solution }}}}[/tex]
Given :-We have given in the question that, A father is 3 times as old as his son 9 years a ago, The father was 4 times as old as his son To Find :-We have to find the present ages of son and father Let's Begin :-Let the present age of son be x
A father is 3 times old as his sonTherefore,
Present age of the father will be
[tex]\bold{ = 3x\:\: years }[/tex]
9 years ago,
The age of the son was
[tex]\bold{ = ( x - 9)\: years}[/tex]
So,Age of the father was
[tex]\bold{ = 3(x - 9) \:years ...eq(1)}[/tex]
But,
It is given that, 9 years a ago father was 4 times as old his son age That is, [tex]\bold{ 4(x - 9) ...eq(2)}[/tex]From eq(1) and eq(2) :-
[tex]\sf{3(x - 9) = 4(x - 9)}[/tex]
[tex]\sf{3x - 27 = 4x - 36}[/tex]
[tex]\sf{3x - 4x = -36 + 27}[/tex]
[tex]\sf{-x = -9 }[/tex]
[tex]\bold{\pink{ x = 9 \: years }}[/tex]
Thus, The present age of the son is 9 years
Therefore,Age of the father will be
[tex]\sf{ = 3 × 9 }[/tex]
[tex]\bold{\red{ = 27 \: years }}[/tex]
Hence, The present ages of son and father is 9 years and 27 years

if it's only asking how much he had after buying the oil pastels, it's just 20-6.20 which is 13.80
y = 2x + 4
6x – 3y = -12
System by substitution 10 points
Answer:
(-2, 0)
Step-by-step explanation:
y = 2x+4
6x - 3y = -12
Start by simplifying the second equation by dividing everything by 3 (this will make the math easier)...
2x - y = -4
Then, substitute 2x+4 for y into the second equation (this is because y = 2x+4)...
2x-3(2x+4)=-4
Distribute the -3
2x-3(2x)-3(4)=-4
2x-6x-12=-4
Combine like terms
-4x-12=-4
Add 12 to both sides
-4x-12+12=-4+12
-4x=8
Divide both sides by -4
x=-2
Plug -2 back in for x to solve for y:
y = 2(-2) + 4
y=-4+4
y=0
(x, y) = (-2, 0)
Answer:
Infinitely many solutions
Step-by-step explanation:
[tex]y=2x+4\\ [2] 6x-3y=-12[/tex] < ------------- Linear equations given
Equations Simplified or Rearranged :
[tex]y - 2x = 4 \\ [2] -3y + 6x = -12[/tex]
Solve by Substitution :
// Solve equation [1] for the variable [tex]y[/tex]
[tex][1] y = 2x + 4[/tex]
// Plug this in for variable[tex]y[/tex] in equation[tex][2][/tex]
[tex][2] -3*(2x+4) + 6x = -12[/tex]

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
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

I need help with this question quick :,) please answer lol
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
