Answer:
D(12) = 2,600 miles
It means a distance of 2,600 miles is already traveled from home after 12 hours
Step-by-step explanation:
To find D(12); all we have to do is to substitute the value of 12 for D
We have this as;
D(12) = 3260-55(12)
D(12) = 2,600
In the context of this problem, what this mean is that the distance away from home is 2,600 miles after traveling 12 hours
Answer:
x= number of songs bought
y= number of movies bought
1.75*x + 2.5*y = 45
x + y = 20
Step-by-step explanation:
Giving the following information:
Robert spent $45 buying songs and movies at an online store that charges 1.75 for each song and $2.50 for each movie he purchased a total of 20 songs and movies combined.
<u>We need to establish a system of equations that represents this situation.</u>
x= number of songs bought
y= number of movies bought
1.75*x + 2.5*y = 45
x + y = 20
<u>Now, we can determine the x and y:</u>
x= 20 - y
Substitute x:
1.75*(20 - y) + 2.5y = 45
35 - 1.75y + 2.5y = 45
0.75y = 10
y= 13
x= 20 - 13
x= 7
<u>Prove:</u>
1.75*7 + 2.5*13 = 45
7 + 13 = 20
Answer: 175
Step-by-step explanation:
Let say
x the number of ticket at $6
y the number of ticket at $10
z the number of ticket at $12
500 total tickets were sold : x+y+z=500
the total income from ticket sales were $4.500: 6*x+10*y+12*z=4500
the combined number of $6 and $10 tickets was four times the
number of $12 tickets sold: x+y=4*z
x=175

For the g=6x you would have to divide the 6 from both sides so it would end up being x=g/6. For Z=m-x you can add the x to both sides making it z+x=m and then subtracting the z from both sides making it x=m-z. Then for u=2x-2 you would have to add 2 to both sides making it u+2=2x and then divide 2 from both sides making it x= 2+u/2.
Answer: slope = ∞ infinito
Step-by-step explanation:
We can use slope formula to find the slope of a line that passes through two points (x₁ , y₁) and (x₂ , y₂)
<h3>m = ∆y/∆x = y₂-y₁/x₂-x₁ </h3>
Given points are: G(x₁ , y₁) = (5,5) and H(x₂ , y₂) = (5,-5)
Substituting these two known points in the slope formula, we have:
m = (-5-5)/(5-5) = -10/0 = ∞ infinito
Therefore, the slope of this line = ∞ infinito
Answer: slope = ∞ infinito
