Which property of equality was used to solve this equation?
x − 5 = -14
x − 5 + 5 = -14 + 5
x = -9
A. addition property of equality
B. subtraction property of equality
C. multiplication property of equality
D. division property of equality
The addition property of equality was used to solve this equation. option A is correct.
A solution is given we have to determine the solution contains which property of equality.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
x − 5 = -14
x − 5 + 5 = -14 + 5
x = -9
We can see, in step 2 5 is added to both sides of an equality, which implies the property of additions.
Thus, the addition property of equality was used to solve this equation. option A is correct.

If l is parallel to m, find the value of each missing variable.
Answer:
x = 26; l = 137; m = 137
Step-by-step explanation:
If the lines are parallel, that means the measurements are too. As such, equal the two expressions together
5x + 7 = 8x - 71
add 71 to both sides
5x + 7 + 71 = 8x - 71 + 71
-71 and +71 cancel each other out
5x + 78 = 8x
subtract 5x from both sides
5x - 5x + 78 = 8x - 5x
5x - 5x cancels each other out
78 = 3x
divide both sides by 3
3x ÷ 3 = 1x which can also be written as just x
78 ÷ 3 = x
26 = x
plug in this x value into both expressions to find variables l and m
l:
5(26) + 7
130 + 7
137
m:
8(26) - 71
208 - 71
137

can somebody help me with this problem!? i need help ahh
for these kinds of problems the outside angle always equals the opposite 2. meaning angle x=64+70 which is 134 degrees. you can double check this because all triangles equal 180 degrees. meaning that the last angle in the triangle is 46. 46+70+64=180.
so your answer is 134.
hope this helps :)
Answer:
134 Degrees.
Step-by-step explanation:
Lets figure out the third angle (y) in the triangle first.
70 + 64 + y = 180
134 + y = 180
y = 46
We now know that 46 is our third angle. Therefore, we can subtract 46 (y) from 180 (the total between x and the third angle) to get our final answer. 134 Degrees.
Meghan has her own business. When she makes money, it is called income. When she spends money, it is called expenses. Choose the phrases below to explain how to use positive or negative integers to represent income and expenses. You would use positive integers to represent income because it is a Choose... amount. You would use negative integers to represent expenses because they are opposites of income.
Answer and explanation:
When you use positive interger to represent income, it shows that there has been an addition instead of a subtraction in money value to the business. In other words money is coming in instead of going out. Example when there is profit on goods sold say $10, it is indicated with a positive integer 10 to indicate addition in terms of operating income
When you use a negative value to represent expense, it indicates there has been a subtraction instead of an addition in money value. In other words money is going out of the business and not coming in. Example when there is a transportation expense to convey goods to the buyer, it is recorded as expenses subtracted from say revenue sales of the business. expenses are usually indicated in brackets in accounting to show negative value, although not a requirement since they are already named and recognized as expenses and subtracted regardless

4/968 how many times does 4 go into 9? 2 times put the 2 above the 9
8 4 times 2 equals 8 so you put the 8 below the 9 and subtract
1 6 9 minus 8 equals 1 than you drop the 6
1 6 how many times does 4 go into 16? 4 times. put the 4 above the 6
0 8 than multiply 4 *4 =16 than 16-16=0 drop the 8
8 4 goes into 8, 2 times the 2 goes above the 8. 4*2=8
0 8-8=0

Write the equation of the parabola in vertex form.
vertex (3,3), point (1, -9)
f(x) =
Can someone help me ASAP??
Answer: -9 = a(1 - 3)² + 3
Step-by-step explanation:
Vertex Form Equation:
y = a(x - h)² + k
vertex: (h, k) which means
h = 3
k = 3
because your vertex is (3, 3).
Your point is (1, -9) which is (x, y).
This means
x = 1
y = -9
Now, plug everything into your Vertex Form Equation:
-9 = a(1 - 3)² + 3
That’s your equation and final answer, but of course, if you need to, you can solve for a if you need to.
If a is positive, the parabola opens up. If a is negative, the parabola opens down.

Factorise (2x+3y)²-(x-4y)²
Answer:
(3x−y)(x+7y)
Step-by-step explanation:
Factor (2x+3y)^2−(x−4y)^2
3x^2+20xy−7y^2
=(3x−y)(x+7y)
Answer:
(3x - y)(x + 7y)
Step-by-step explanation:
Given
(2x + 3y)² - (x - 4y)² ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b)
Here a = 2x + 3y and b = x - 4y , then
(2x + 3y + x - 4y)(2x + 3y - (x - 4y))
= (3x - y)(2x + 3y - x + 4y) = (3x - y)(x + 7y)
Thus
(2x + 3y)² - (x - 4y)² = (3x - y)(x + 7y) ← in factored form
