Add the two equations together to get:
4y = -4
Solve for y by dividing both sides by 4:
Y = -1
Now you have a value for y, solve for x in the first equation:
2x + 3(-1) = 7
2x -3 = 7
Add 3 to both sides:
2x = 10
Divide both sides by 2:
X = 5
Answer: x = 5 and y = -1

Okay so first
-3 - 4
---------
-1 - (-1)
When you subtract a negetive its really just adding so
-3 - 4
---------
-1 + 1
-3 - 4 is -7
-1 + 1 is 0
now we have -7/0
Which means our slope does not go horizontally at all! it only goes vertical
this actually means our slope is just undefined

Inverse operationsare pairs of mathematical manipulations in which one operation undoes the action of the other—for example, addition and subtraction, multiplication and division. The inverse of a number usually means its reciprocal, i.e. x - 1 = 1 / x . The product of a number and its inverse (reciprocal) equals 1.

4x-7y=14 y intercept and slope, show work
Answers
Answer:
slope = 4/7 & y-intercept = -2
Step-by-step explanation:
4x - 7y = 14 (step 1: original equation)
-4x -4x (step 2: remove 4x, BS)
-7y = -4x + 14
7y = 4x - 14 (step 3: switch signs)
y = 4/7x - 2 (step 4: divide BS by 7)
In the form y = mx + b, b is the y-intercept and m is the slope. In this case, our b (y-intercept) is (0, -2) or just -2. Our m (slope) is 4/7 (four sevenths).
Please help me with solving what is y. Thanks!

If two types of matter are combined and energy is given off, what type of change is likely to have occurred?
chemical change
physical change
particle change
shape change
Answers
Answer:
Chemical change
Explanation:
If two types of matter reacts or are combined and energy is given off, the type of change that might have occurred is a chemical change. A chemical change is one in which a new kind of matter is formed. It is always accompanied by energy changes. The process is not easily reversible. When an exothermic reaction or change occurs, heat is released and it is a typical characteristic of chemical change.

rate = 1.2%
time = 20 years
Step two:
The simple interest is expressed as
SI= PRT/100
substitute
SI= 2500*1.2*20/100
SI= $600
The account balance after 20 years is
= principal + Simple interest

write 15 + 45 as a product of two factors using the gcf and the distributive property.
15 + 45 = ? (? + ?)
Answers
Answer:
15 (3+1)
Step-by-step explanation:
Hope this helps :)
The solution is 15 + 45 = 15 ( 1 + 3 )
The greatest common divisor of 15 and 45 is 15 and the equation is simplified as 15 + 45 = 15 ( 1 + 3)
What is Greatest Common Factor?
The Greatest Common Divisor is the highest number that divides exactly into two or more numbers. It is also expressed as GCF
Given data ,
Let the equation be represented as A
Now , the value of A is
15 + 45 = a ( x + y )
Let the first number be A
Now , the value of A = 15
Let the second number be B
The value of B = 45
The factors of 15 = 1 , 3 , 5 , 15
The factors of 45 = 1 , 3 , 5 , 9 , 15 , 45
Now , the greatest factor of both 15 and 45 is the number 15
So , the equation will be simplified as
The value of a = 15
So ,
15 + 45 = 15 ( x + y )
The value of x + y = 4
And , x = 1 and y = 3
Substituting the values of x and y in the equation , we get
15 + 45 = 15 ( 1 + 3 )
Therefore , the value of a = 15
Hence , the greatest common divisor of 15 and 45 is 15
