Answer:
(3, -1)
Step-by-step explanation:
Multiply the 2nd equation (-2x-3y=-3) times -3 to eliminate x
Subtract/add the other terms -y + 9y and -17 + 9
Then divide 8y = 8
y= -1
Substitute y in the other equation
x = 3
(3, -1)
Answer:
Point Form: ( 3 , − 1 )
Equation Form: x = 3 , y = − 1
Step-by-step explanation:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
Write an equation of the line that passes through the point (8, -1) and is perpendicular to the line pictured.
A) y = 4x
B) y = 4x + 1
C) y = -1/4x
D) y = -1/4x + 1
You operate a fresh fruit and vegetable market. For normal shipments, about 9.0% of the peaches are spoiled when they reached your market. You anticipate a busy weekend and would like to have 100 pounds of peaches to sell. To have 100 pounds of peaches and considering the spoilage rate, how many pounds should you order?
Answer:
110 pounds of peaches should be ordered
Step-by-step explanation:
Here, we want to calculate the number of pounds of peaches to order.
Let the number of peaches to ordered be x peaches
Now, since 9% is expected to be bad, then the percentage expected to be good will be 91%
Thus;
91% of x = 100
91/100 * x = 100
91x = 100 * 100
x = 10000/91
x = 109.89
Since we cannot have fractional peaches, then x must be 110

Given that the point (-9,6) is on the graph of f(x) find the corresponding point for the function-1/2 f (x)
9514 1404 393
Answer:
(-9, -3)
Step-by-step explanation:
For x=-9, we have f(x) = 6.
For x=-9, -1/2f(x) = -1/2(6) = -3. The corresponding point is (-9, -3).
A square has an area of 9yd^2. What is the length of each side?
Answer: The side length is 3 yards.
Step-by-step explanation:
To find the area of a square, you have to square one of it's side lengths since they all share the same length. Since we know the area, and we need to find the side length so we just need to find the square root of the area.
[tex]\sqrt{9}[/tex] = 3
The side length is 3 yards.
The length of each side of a square is, 3 yards.
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
We have to given that;
⇒ An area of square = 9 yards²
Now, We know that;
⇒ Area of square = Side²
Let the side of square = a
So, We get;
⇒ a² = 9
⇒ a = √ 9
⇒ a = 3 yards

Prove that if -5(x + 4) = 70, the x = -18. Write a justification for each step.
Step-by-step explanation:
Let's solve your equation step-by-step.
−5(x+4)=70
Step 1: Simplify both sides of the equation.
−5(x+4)=70
(−5)(x)+(−5)(4)=70(Distribute)
−5x+−20=70
−5x−20=70
Step 2: Add 20 to both sides.

A map of Colorado says that the scale is 1 inch to 20 miles or 1 to 1,267,200. Are these two ways of reporting the scale the same? Explain your reasoning.
Answer:
1,267,200
Step-by-step explanation:
Given that the map reported that the scale is 1 inch to 20 miles.
Recall that there are 63,360 inches in 1 mile, thus, in 20 miles, we have 20 x 63,360 = 1,267,200
Therefore, the scale of 1 inch to 20 miles can also be represented as 1 to 1,267,200

In training for a swim meet, Logan swam 750 meters in 1.3 of a hour. His swimming partner , Mila swam 2.3 of Logan's distance in 1.4 of a hour. What is Logan's average swimming speed? What is Mila's average swimming speed? Compare Mila's and Logan's swimming speed.
Answer:
Step-by-step explanation:
For Logan:
Logan swam 750m
Logan distance = 750m
Time taken = 1.3×3600
Time taken = 4680
Logan average speed = distance/time
average speed = 750/4680
Logan Average speed = 0.160m/s
Mila swam 2.3 of Logan's distance
Milan distance = 1725m
Time taken = 1.4×3600
Time taken = 5040s
Milan average speed = distance/time
Milan average speed = 1725/5040
Milan average speed = 0.342m/s
Comparing Milan speed with Logan speed:
Difference in speed = 0.342-0.160
Difference in speed = 0.182m/s
This means that Milan speed is 0.182 greater than Logan speed.
what is the solution to the equasion 1/2x + 3= 2/3x + 1
Answer:
12
Step-by-step explanation:
1/2x+2=2/3x
2= 2/3x-1/2x
2=4/6x-3/6x
2=1/6x
multiply both sides by 6
x=12
Answer: x = 12
Step-by-step explanation:
1/2x + 3= 2/3x + 1
= 1/2x + 3 - 3 = 2/3x +1 -3
Simplify
= 1/2x = 2/3x -2
= -1/6x = -2
multiply both sides by -6
(-1/6x)(-6) = (-2)(-6)
x = 12
