Solve each system by eliminantion: -5x+3y=6 x-y=4
Answer: x = -9 , y = -13
Step-by-step explanation:
Multiply the second equation by 5, then add the equations together.
(−5x+3y=6)
5(x−y=4)
Becomes:
−5x+3y=6
5x−5y=20
Add these equations to eliminate x:
−2y=26
Then solve −2y=26 for y:
−2y = 26
Divide both sides by -2
y= -13
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
−5x+3y=6
Substitute−13 for y in −5x+3y=6:
−5x+(3)(−13)=6
−5x−39=6 (Simplify both sides of the equation)
−5x−39+39=6+39 (Add 39 to both sides)
−5x=45
Divide both sides by -5
x = -9

A bookstore took in $167 on sale of 5 copies of a new cookbook and 3 copies of a new novel. The next day it took in $89 on the sales of 3 copies of the cookbook and 1 copy of the new novel. What was the price of each book.
Hint: use elimination or substitution
The price is $14 for each novel and $25 for each Cookbooks when a bookstore made $167 on the sale of 3 new novels and 5 copies of a new cookbook.
Given that,
A bookstore made $167 on the sale of 3 new novels and 5 copies of a new cookbook. Three cookbook copies and one copy of the brand-new book were sold the next day, bringing in $89 for the company.
We have to find what the cost of each book was.
We know that,
A bookstore took in$ 167 on the sale of 5 copies of a new cookbook and 3 copies of a new novel.
The next day it took in $ 89 on the sale of 3 copies of the cookbook and 1 copy of the novel.
What is System of equation?An algebraic expression-based system of equations is a collection of relationships between several unknown variables.
Now,
Let x= cookbook and y= novel.
So,
On first day, 5x + 3y = 167----->equation(1)
On second day, 3x + 1y = 89----->equation(2)
These equations must be solved in order to determine the cost of each book.
From equation(2), we get;
y = 89 - 3x
Now we use this x solution to solve our first equation.
We get;
5x + 3(89-3x) = 167
5x + 267 - 9x = 167
267-167 = 9x - 5x
100 = 4x
x = 25
So, The price is $25 for the each Cookbooks.
Now, By substituting $25 for x in the second equation, we must get the value of y.
y=89-3(25)
y=89-75
y=14
So, The price is $14 dollars for each novel.
So,
Therefore, The price is $14 for each novel and $25 for each Cookbooks when a bookstore made $167 on the sale of 3 new novels and 5 copies of a new cookbook.

The equation that has a real zero at x = 2 is y = -[tex]2^x[/tex] + 4.
Option A is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
The graph shows an x-intercept at x = 2, which means that the function has a real zero at x = 2.
Now,
We can check which of the given equations has this property by plugging in x = 2 and seeing if the corresponding y-value is zero.
For y = [tex]-2^x[/tex] + 4,
y = -2² + 4 = 0
This equation has a real zero at x = 2.
For y = 2^x,
y = 2² = 4,
This equation does not have a real zero at x = 2.
For y = log₂(x + 2) + 1,
y = log₂(2 + 2) + 1 = log₂4 + 1 = 3
This equation does not have a real zero at x = 2.
For y = log₂(-x + 2),
-x + 2 < 0, which means that x > 2.
This equation does not have a real zero at x = 2.

If we randomly select a U.S. female, is (pregnant and over 55) = (0.06)(0.27) = 0.0162? Why or why not?
No, because being older than 55 and being pregnant are not independent events.

A random number is one that is selected by chance, or randomly, from a set of numbers, as the name suggests. There is an equal chance that any one of the numbers in a given distribution will be chosen at random.
The concepts of randomness are formally defined in the fields of mathematics, probability, and statistics. A random variable in statistics is the process of assigning a numerical value to each potential result of an event space. The identification of the events and the estimation of their probabilities are made easier by this association.

A relation i plotted a a linear function on the coordinate plane tarting at point A (0, 3)and ending at point B (2, 7). What i the rate of change for the linear function and what i it initial value? Select from the drop-down menu to correctly complete the tatement. The rate of change i Chooe. And the initial value i Chooe.
The rate of change is 2 and initial value is 3.
Given points A (0,3) B(2,7)
What is the slope of line joining between point A and point B
if let's suppose A(x1,y1) B(x2,y2)
then slope(m) = y2-y1/x2-x1
x1=0,y1=3
x2=2 y2= 7
slope(m) = 4/2 = 2
The ratio between the change in the values of the y variables and the change in the values of the x variables is known as the rate of change. The rate of change is the slope of the line if the rate of change is linear and constant.
Rate of change of linear function is also know as slope of that linear function.
So here slope itself is the rate of change.
Initial value is 3 as Coordinate of A is (0,3).

based on the angle measures list the sides (AB,BC, and AC). In order from shortest to longest:
Order of Sides from smallest to largest is AC, BC , AB.
What is the order of Angles and Sides in a Triangle ?Finding the Triangle's Angles and/or Sides in Order of Largest to Smallest
Step 1: As stated in the issue, sort the supplied angles or sides in the order of smallest to greatest or largest to smallest.
If the sides are supplied in the issue and we are requested to arrange the angles, step 2 is to find the angles that are opposite the given sides.
If the problem specifies the angles and asks us to arrange the sides, find the sides that are perpendicular to the provided angles.
The sides opposing the angles will be listed in the same sequence as step 1's first-identified sides. Therefore, the side across from the biggest angle will be the largest, and the side across from the smallest angle will be the smallest. The angles opposing the sides will also be in the same sequence as those found in step 1 for the angles. As a result, the angle opposite the side with the greatest length will be the largest, while the angle opposite the side with the lowest length will be the smallest.
angle B is smallest , so the smallest side is opposite side of angle B i.e AC.
Again angle C is largest so similarly AB is the largest.
Order of Sides from smallest to largest is AC, BC , AB

Madelyn is throwing a pizza party. She has 6 pounds of cheese available and she
needs 1/2 pound of cheese to make each pizza. How many pizzas can she make?
Answer:
She can make 12 pizzas
Step-by-step explanation:
There are 2 halves in a pound, so you'll need to do 6 × 2 = 12.
Bernard was going on an 3.5 kilometre bushwalk. He needs 1.2 litres of water for every 1.4 kilometres he walks. He only has 500 mL water bottles. How many water bottles will he need to take to make sure he has enough water for his walk?
The number of water bottles Bernard needs to complete a 3.5 kilometer bush walk is 6 bottles of 500 mL
The number of water bottles = 6
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 number of water bottles required be = A
Now , the equation will be
The total distance of the bush walk = 3.5 km
Bernard's requirement of water for every 1.4 km = 1.2 L of water
So , Bernard's requirement of water for every 3.5 km = ( total distance of the bush walk / 1.4 ) x 1.2 L
Substituting the values in the equation , we get
Bernard's requirement of water for every 3.5 km = ( 3.5 / 1.4 ) x 1.2 L
Bernard's requirement of water for every 3.5 km = 2.5 x 1.2 L
Bernard's requirement of water for every 3.5 km = 3 L
Now , the amount of water one water bottle can hold = 500 mL
The value of 3 L = 3000 mL
So , the number of water bottles required to hold 3 L = 3000 / amount of water one water bottle can hold
Substituting the values in the equation , we get
The number of water bottles required to hold 3 L = 3000 / 500
The number of water bottles required to hold 3 L = 6 water bottles
Therefore , the value of A is 6 water bottles
Hence , The number of water bottles Bernard needs to complete a 3.5 kilometer bush walk is 6 bottles of 500 mL
