Solve the system of linear equations by substitution.
y=−4x−9
4x−y=1
Answer:
x=-1, y=-5 ---> (-1, -5)
Step-by-step explanation:
so you want to plug one equation into the other. so start off by plugging y=−4x−9 into the y value of 4x−y=1-----> 4x-(-4x-9)=1. now subtract and isolate x which ends up being x=-1. now plug the x=-1 into either equation and isolate and solve for your y value which ends up being y=-5. you can check you answer by plugging both the x and y you found into one equation and making sure the answer it gives is true. ;)
The solution for equations y=-4x-9 and y=-4x-9 is x=-1, y=-5.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equations are,
y=-4x-9 (1)
4x-y=1 (2)
From equation (1), substitute the value of y in equation (2)
4x-(-4x-9)=1
8x+9=1
8x=-8
x=-1
Substitute x=-1 in equation (1),
y=-4(-1)-9
y=4-9
y=-5
The value of x is -1 and y is -5

An ice cream parlor donated 6 containers of ice cream to a local elementary school. Each container holds 3 gallons of ice cream. If each student is served 1 cup of ice cream, how many students can be served?
Answer:
288 students can be served
Step-by-step explanation:
Looking at the donation made by the ice cream parlor, we want to know the number of students to be served.
We need to achieve a consistency in units first. What I mean by this is that all our units must be the same.
The parlor donated 6 containers with each container holding 3 gallons. The amount donated is thus 3 * 6 = 18 gallons of ice cream
Mathematically, there are 16 cups in a gallon. Thus, the amount of cups donated by the parlor would be 16 * 18 = 288 cups
Now since 1 student takes 1 cup of ice cream, the number of students that the donation can serve is 288/1 = 288 students

In a class 27 of students, 12 have a cat and 11 have a dog. There are 5 students who have a cat and a dog. What is the probability that a student has a dog given that they have a cat?
Answer:
41.67% probability that a student has a dog given that they have a cat
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: having a cat.
Event B: having a dog.
12 of 27 students have a cat:
This means that [tex]P(A) = \frac{12}{27}[/tex]
5 students who have a cat and a dog.
This means that [tex]P(A \cap B) = \frac{5}{27}[/tex]
What is the probability that a student has a dog given that they have a cat?
[tex]P(B|A) = \frac{\frac{5}{27}}{\frac{12}{27}} = \frac{5}{12} = 0.4167[/tex]
41.67% probability that a student has a dog given that they have a cat

You pick a card at random. Without putting the first card back, you pick a second card at random.
What is the probability of picking a 3 and then picking a 3?
Simplify your answer and write it as a fraction or whole number.
Answer:
The answer could be 0 or 1 out of 4, because choosing a card at first and not putting it back, then picking a second card at random, it would likely be one in zero attempts to pick 3 again but otherwise that it could be 1 out of 4 because it could be possible picking 3 at the first try.

The square of 2.8 is 78.4
(step by step explanation)
answer fastly
The answer is false.
The square of 2.8 is actually 7.83999 or 7.84 if rounded.
To get this, we simply bring 2.8 to the power of 2.
2.8 x 2.8 = 7.8399
Therefore, the answer would be false since the actual square of 2.8 is 7.84
ABC is an isoscles triangle. Angle A = 40°.
Find measure of Angle B.
40
70
75
180
Answer:
70 degrees
Step-by-step explanation:
total angle in a triangle is 180 degrees
180-40= 140
Angle b and c is total of 140 degrees
they are isosceles so their measurements would be same.
angle b and c is 140÷ 2 = 70
so angle b is 70 degrees
PLEASE HELP which equation in the word bank can solve for x ?
Answer:
x + 10 = 24
Step-by-step explanation:
In the figure attached,
There are two external points A and B.
Fro point A two tangents AD and AE have been drawn and From point B tangents BE and BC have been drawn.
Since AD = 10 units,
Therefore, AE = 10 units
(Since tangents drawn from a point to a circle are same in measure, therefore, AD = AE)
Therefore,
BE = AB - AE
Since BE = BC
So BC = AB - AE
x = 24 - 10
x + 10 = 24
Therefore, (x + 10) = 24 will be the equation to be used to solve for x.

Large rectangle: 5 x 12
Smaller rectangle: 4 x 6
Square: 2 x 2
Triangle: 4 x 3
Step 2) Find the area of each shapes
Large rectangle: A = 5 x 12 = 60
Smaller rectangle: A = 4 x 6 = 24
Square: A = 2 x 2 = 4
Triangle: A = 1/2 x 4 x 3 = 6
Step 3) Add all of the areas together
A = 60 + 24 + 4 + 6 = 94 square miles

How to expand the following problem
Devon purchased one bag of dog food and three bags of cat food. Each bag of dog food weighs x pounds and each bag of cat food weighs half as much as the bag of dog food. The total weight of Devon's purchase is 32.5 pounds. The equation x+3(x/2)=32.5 can be used to determine the weight of the dog food and cat food. What is the weight in pounds of one bag of cat food?
Answer:
A pound of cat food will weigh 6.5 pounds
Step-by-step explanation:
Firstly, we need to get the value of x. Thus, let’s solve the equation at hand;
x + 3x/2 = 32.5
x + 1.5x = 32.5
2.5x = 32.5
x = 32.5/2.5
x = 13
Now from the question, we are made to know that a pound of cat food measures half of what a pound of dog food measures
Since we calculate a pound of dog food to weigh 13 pounds, a pound of cat food will weigh = 13/2 = 6.5 pounds
340 students went to the first school dance, the last school dance 306 students attended. What is the percent of change between the two dances?

Answer:
10.59%
Step-by-step explanation:
percentage of change is given by
{(old number - new number)/old number} * 100
_________________________
given
no. of student went to the first school dance = 340
no. of student went to the last school dance = 306
Percentage of change between two dance
= ((no. of student went to the first school dance - no. of student went to the last school dance)/ no. of student went to the fist school dance)*100
= (340 - 306)/340 *100
= (36/340 )*100 = 10.59%
The percent of change between the two dances 10.59%.

50 POINTS! Carol is designing an artistic picture frame, which she wants to sell online. The picture frame will be square, but will come in several different sizes. She plans to place decorative stones around the outside of the picture frame. Carol’s first step was creating this prototype frame. (The first picture attached) You will be helping Carol form expressions that will tell her the number of stones she’ll need to order for each frame.
Part A:
How many stones make up the perimeter of the prototype picture frame? Perimeter is usually calculated by adding the length of each side of a shape. In the prototype, there are four stones per side. If we try to find the total number of stones in the frame by adding the number of stones per side, we’ll get an incorrect total. Why?
Part B:
Suppose that s equals the number of stones on one side of the picture frame. Write an expression that would give the number of stones in the top and bottom sides together.
Part C:
Write an expression in terms of s that represents the remaining stones. (The second attached picture) Write an expression in terms of s that represents the remaining stones.
Part D:
Now combine the two expressions you wrote in parts b and c by adding them together. What does the expression formed by this operation represent?
Answer: 12 stones
Step-by-step explanation:
The side of the length will be x = √m square inches.
What is the area of square and a rectangle?The area of the square and rectangle is -
Square = [x]² {x is the side of a square]
Rectangle = L x B {L is the length and B is breadth}
here, we have,
Given is Lisa who is decorating outside edge of a square picture frame. She needs to know the side length of the frame. The area of the frame is [m] square inches.
It is given that the the area of the square is [m] square inches.
Assume that the length of the side is [x] inches.
x² = m
x = ±√m
Side cannot be negative.
Therefore, the side of the length will be - x = √m
Therefore, the side of the length will be x = √m square inches.
