Answer:
Y=-1/2x+4
Step-by-step explanation:
-The slope is -1/2 so you just plug it in where the slope would go with an x in front
-all you need now is your y-intercept which can be found by plugging in the provided info to your basic form y=mx+b
-You can take the provided point at (10,-1) and work out what the intercepts is
-1=-1/2(10)-b
-1=-5-b
4=b
Answer:
143.70 = 3(39.95) + x
where x is the additional fee spent to race the cars at the park
Step-by-step explanation:
Let’s write the complete question first before we solve;
Blake and two of her friends are going to an amusement park. The cost of admission to the park is $39.95 per person. Once they are in the park, Blake and her friends ride the race cars, which require an additional fee. The total amount spent by all three boys is $143.70. Write an equation that can be used to find the additional fee to ride the race cars.
solution;
we are trying to write an equation that could help determine the additional fee used to race cars at an amusement park by a group of friends.
we proceed as follows;
We identify that they are 3, with each spending an amount equal to $39.95 for admission.
now to find the additional fee, we simply multiply the admission fee by 3 and subtract from the total amount spent.
let’s say the additional fee is x
This means;
143.70 = 3(39.95) + x
To get x, we can then open the bracket then take the value to the other side to get x
Answer:
It will take 3 years and 9 months or simply 3.75 years
Step-by-step explanation:
For his money to grow to $950, this means he had earned an interest of the value $950 - $800 = $150
Now, to calculate the number of years it took to earn this interest, we make use of the simple interest formula
mathematically,
I = PRT/100
since we are looking for T, we can rewrite the equation to be?;
100I = PRT
T = 100I/PR
where I is the interest which is $150
R is the rate charged on the deposit and that is 5% per annum
P is the amount deposited initially which is 800
while I is the interest which is $150
Now plugging these values;
T = (100 * 150)/(5 * 800)
T = 15000/4,000 = 3.75 years or simply 3 + (0.75 * 12) = 3 years 9 months
Answer:
The greatest value is "e"
Step-by-step explanation:
We have the following equations:
a. 1.31 a = f
b. 1.12b=f
c. 1.01c=f
d. 0.98d=f
e. 0.31e =f
Then solving for "a", "b", "c", "d" and "e" we have:
a. a = f /1.31
b. b=f/1.12
c. c=f /1.01
d. d=f / 0.98
e. e=f / 0.31
Now, given that in all the equations "f" represents the same number, the gratest value it's going to be the option in which "f" is divided by the smaller number.
The option in which f is divided by the less number is option e because, in this case, f is divided by 0.31.
Answer:
B because the length of R to U is 6x5
