Answer:
(1.63,4.18)
Step-by-step explanation:
1) look at the graph below: they intersect at about (1.5,4)
lets solve the systems by substitution:
since both equations are equal to y lets substitute the second equation into the first:
-6x+14=5x-4
-6x-5x=-14-4
-11x=-18
x=1.63
lets substitute x in the first equation:
5(1.63)-4=4.18
Hope this helps!
In 10 minutes Joey eat 52 hot dogs
Step-by-step explanation:
In one minute Joey can eat 5.2 hot dogs
In 10 minutes how many hot dogs should Joey eat?
Solving:
In one minute Joey can eat hot dogs = 5.2
In 10 minutes Joey can eat hot dogs = 5.2*10
In 10 minutes Joey can eat hot dogs = 52
So, in 10 minutes Joey eat 52 hot dogs

( x - 8 )² = 144 / √ (take the square root of both sides of equation )
x - 8 = 12
x = 20 feet
Answer: D) 20 feet by 20 feet
Answer:
We know that below the third quartile we have 75% of the values and below the first quartile we have 25% of the values. Then between the third and the first quartile we will have 75-25%=50% of the values.
And then we can apply the following proportion rule:
And solving for x we got:
So then the total of students is approximately 708
Step-by-step explanation:
We know that 354 students are between 100 and 130 so then the interquartile range is:
We know that below the third quartile we have 75% of the values and below the first quartile we have 25% of the values. Then between the third and the first quartile we will have 75-25%=50% of the values.
And then we can apply the following proportion rule:
And solving for x we got:
So then the total of students is approximately 708
Answer:
Slope m = -(x+2)
The Slope of the secant m = 1
Step-by-step explanation:
From the given information:
The slope of the line passing through P(-2,-4) and Q ( x, f(X)) can be calculated as :
Slope m =
Slope m =
Slope m =
Slope m =
Slope m = -(x+2)
Passing through P(-2,4) and Q(-3,3)
Slope of the secant m = -(x+2)
Slope of the secant m = -(-3 +2)
Slope of the secant m = -( -1)
The Slope of the secant m = 1
