Answer:
-5/8
Step-by-step explanation:
Convert standard form to slope-intercept form to find the slope.
5x + 8y = 50
8y = -5x + 50
y = -5/8x + 50/8
Slope: -5/8
Answer:
-5/8x
Step-by-step explanation:
First you need to find the slope of the given line.
Do this by converting it to slope intercept form (y=mx+b)
Divide the whole equation by 8 to isolate the y variable.
After dividing by 8 you should now have 5/8x + y = 6.25
Now you need to subtract y and 6.25 to isolate y
5/8x - 6.25 = -y
Now you have to divide the whole equation by negative 1 to make y positive. You end up with: y = -5/8 + 6.25
We know that the slopes of parallel lines are equal. Therefore the answer is -5/8x

solve 1/5^2x+10 = 25^3x
Answer:
-5(3x+4) = 25
-15x-20=25
-15x=25+20
-15x=45
>then divide both side by -15
Therefore: X=-3
4(x+2)-3(2x-4)=10
4x+8-6x+12=10
-2x+20=10
-2x=-10
> divide both sides by -2
Therefore: x= 5

A sum of money is deposited at a bank at a rate of 12½ annum simple interest. In how many years would the deposited money be doubled
Answer:
It would take 10 years for the given sum of money be doubled at the given simple interest rate.
Step-by-step explanation:
A 10% interest would be added to the the principal amount after each year. So the interest would reach 100% i.e. equal to the principal amount in 10 years.

2 cars c and d started to move to each other car c was 118 miles from Boston car d was 256 miles from Boston car c was going twice as fast as car d how. Far from Boston will these 2 cars meet
Answer:
131.3 miles
Step-by-step explanation:
The two cars are moving from different directions. The total distance between the two cars = 118 miles + 256 miles = 374 miles.
Let us assume that the two cars meet at point O, let the distance between car c and O be d₁, the distance between car d and point O be d₂, hence:
d₁ + d₂ = 374 miles (1)
Let speed of car d be x mph, therefore speed of car c = 2x mph (twice of car d). If it take the cars t hours to meet at the same point, hence
For car c:
2x = d₁/t
t = d₁ / 2x
For car d;
x = d₂/t
t = d₂/ x
Since it takes both cars the same time to meet at the same point, therefore:
d₁/2x = d₂ / x
d₁ = 2d₂
d₁ - 2d₂ = 0 (2)
Solving equation 1 and 2 simultaneously gives d₁ = 249.3 miles, d₂ = 124.7 miles
Therefore the distance from point of meet to Boston = 249.3 - 118 = 131.3 miles
Both the cars will meet at 131.33 miles from Boston.
Solution of the system of equations:Pair of equations with two variables is called a system of equations.These equations can be solved by substitution, subtraction or addition method to get the values of the variables.Values of variables is the solution of system of equations.
Given in the question,
Two cars C and D are moving towards each other.Distance between Boston and cars C and D are 118 miles and 256 miles respectively.Speed of car C is double of car D.Distance between two cars = 118 + 256 = 374 miles
Let these cars meet at a point P.
Let the distance between the car C and point P = 'x' miles
Therefore, distance between car D and point P = (374 - x) miles
Time taken 't' by car C to travel the distance 'x' miles,
[tex]\text{Time}=\frac{\text{Distance}}{\text{Speed}}[/tex]
[tex]t=\frac{x}{2v}[/tex] -------(1)
Time taken 't' by the car D to travel (374 - x) miles,
[tex]t=\frac{(374-x)}{v}[/tex] ---------(2)
Substitute the value of 't' from equation (2) to equation (1),
[tex]\frac{x}{2v}=\frac{374-x}{v}[/tex]
[tex]\frac{x}{2}=374-x[/tex]
[tex]\frac{3x}{2}=374[/tex]
[tex]x=249.33\text{ miles}[/tex]
From the picture attached,
Distance between Boston and the meeting point = (x - 118) miles
= 249.33 - 118
= 131.33 miles
Therefore, both the cars will meet at a point 131.33 miles distant from Boston.

The first five terms of a geometric sequence are given above.
Write a recursive function rule for the sequence.
a
f\left(n\right)=3f\left(n\right)+2
b
f\left(n\right)=2n
c
f\left(n\right)=3f\left(n-1\right),\ n1=2
d
f\left(n\right)=3n+2
9514 1404 393
Answer:
[tex]\text{c. }f(n)=3f(n-1);f(1)=2[/tex]
Step-by-step explanation:
The first term is 2, so part of the recursive definition is ...
f(1) = 2
The common ratio is 6/2 = 3, so each term is 3 times the previous one. That part of the recursive definition is ...
f(n) = 3·f(n -1)
These two parts of the definition match choice C.

There are 5 ¾ feet of lights to wrap around a pillar. Every time the lights wrap around, it uses up ⅛ ft of the lights. How many times can the lights be wrapped around the pillar?
Answer: 46
Step-by-step explanation:
From the question, we are informed that there are 5 ¾ feet of lights to wrap around a pillar and that every time the lights wrap around, it uses up ⅛ ft of the lights.
The number of times that the lights can be wrapped around the pillar will be:
= 5 ¾ feet ÷ ⅛ ft
= 23/4 / 1/8
= 23/4 × 8
= 46 times

Z= ?
Answer:
z=(-6)
Step-by-step explanation:
(2/3)*z=(-4)
2*z=3*(-4) --> We move the 3 from the left to the right part of the equation. It was dividing, so we move it multiplying.
2*z=(-12)
z=(-12)/2 --> It's the inverse case of before. 2 was multiplying, so we move it to the right by dividing it.
