8x - 5y =-18
2x + 5y = 58
Answer:
(4,10)
Step-by-step explanation:
8x - 5y = -18
+ 2x + 5y = 58
10x = 40
Dive both sides by 10.
x = 4
2x + 5y = 58
2(4) + 5y = 58
8 + 5y = 58
5y = 50
y = 10
Cheese sticks that were previously priced at "10 for $1" are now "4 for $1". Find each percent change
Answer:
The price per cheese stick was increased by 150%.
The amount of cheese sticks per $1.00 has decreased by 60%.
Step-by-step explanation:
The price per cheese stick was $0.10
1.00 (dollar) divided into 10 (cheese sticks) gives you 0.1, which means each cheese stick costs $0.10The current price per cheese stick is $0.25
1.00 (dollar) divided into 4 (cheese sticks) gives you 0.25, which means each cheese stick costs $0.25That means the price per cheese stick was raised by 150%.
That also means the amount of cheese sticks you could buy for $1.00 has decreased by 60%.

The equation y =f(x) is graphed on the coordinate plane. A function, g(x). is the result of translating the graph of fuxi to the left 2 units and up 4 units. Which is an equation for g(x)?
A)g(x)=f(x - 2)+4
B)g(x) = f(x + 2) + 4
C)g(x)=f(x-4)-2
D)g(x)=f(x + 4)-2
Answer:
A
Step-by-step explanation:
g
[tex]g(x) = f(x - 2) + 4[/tex]
A function assigns the value. The equation of the function g(x) will be f(x-2)+4.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given f(x) is a function which is shifted two units to the right and 4 units upwards. Therefore, in the function f(x) we need to add -2 to the value of the x for the function to move right, while we need to add 4 to the overall function to move it four units upwards.
Hence, the equation of the function g(x) will be f(x-2)+4.

Trey has a bookcase with 8 shelves. Each shelf has 40 books. How many books are in the bookcase
Answer:
8x40=320
Step-by-step explanation:
According to the given question we can infer that here are 320 books in the bookcase.
If Trey has a bookcase with 8 shelves, and each shelf has 40 books, the total number of books in the bookcase can be calculated by multiplying the number of shelves by the number of books per shelf.
Total number of books = Number of shelves × Number of books per shelf
Total number of books = 8 shelves × 40 books per shelf
Calculating the multiplication:
Total number of books = 320 books
Therefore, there are 320 books in the bookcase.

Alex drives at an average speed that is 2/5 of the average speed that Roy's train travels. Alex takes 30 minutes to travel 50 km in her car. Roy travels for 1 hour and 20 minutes on his train. How far does Roy travel to 2 dp (decimal places)?
Answer: 333.33km
Step-by-step explanation:
Average speed is calculated as:
= Distance / Time
Since Alex takes 30 minutes to travel 50 km in her car, Alex average speed will be:
= 50km / 30minutes
= 50km / 0.5hour
= 100km/hour
Since Alex drives at an average speed that is 2/5 of the average speed that Roy's train travels. Roy's average speed will be:
= 100 ÷ 2/5
= 100 × 5/2
= 250km/hour
Since Roy travels for 1 hour and 20 minutes on his train, his distance travelled will be:
= Speed × Time
= 250 × 1 hour 20 minutes
= 250 × 1 20/60
= 250 × 1 1/3
= 250 × 4/3
= 1000/3
= 333.33km
Roy travels 333.33km

To solve x^2+5x=0, mia rewrote the equation as x(x+5)=0. Explain how rewriting this equation in factor form enable mai to solve the equation.
The solution to the equation x² + 5x = 0 is x = 0 or x = -5
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
x² + 5x = 0 be equation (1)
Now , on simplifying the equation , we get
On factorizing the equation , we get
Taking the common factor x ,
x ( x + 5 ) = 0
Now , x can take 2 values which will satisfy the given equation
when x = 0 or ( x + 5 ) = 0
when x = 0
Substitute the value of x in the equation , we get
0 ( 0 + 5 ) = 0
0 = 0
The equation is true when x = 0
And ,
when ( x + 5 ) = 0
Subtracting 5 on both sides of the equation , we get
x = -5
when x = -5
-5 ( -5 + 5 ) = 0
-5 x 0 = 0
0 = 0
The equation is true when x = -5
Hence , the solution is 0 , -5
