Answer:
x=7
Step-by-step explanation:
1. -2x+3=-11 << first make sure the x is one one side of the equal sign. so remove the 3, by subtracting if from 11
2. -2x+3=-11
-3 -3
=
3. -2x= -14 << then so isolate the x= divide -2 from -14 (two negatives divided equals a positive)
4. x=7
To compute the perimeter of a rectangle, you add the length, l , and width, w , and double this sum.
This means you can find the perimeter of a rectangle by evaluating the expression 2 (1 + w ).
Use this expression to find the perimeter of a rectangle with length 30 and width 75.
210 (A)
135 (B)
180 (C)
107 (D)
Answer:
210 (A)Step-by-step explanation:
Use the formula:
P = 2(l + w)Substitute the values and find P:
P = 2(30 +75) = 2(105) = 210Correct choice is A
Answer:
given length [l]=30
width[w]=75
perimeter= 2 (l + w )=2(30+75)=210
so
answer is A.210

Answer:-2
Step-by-step explanation:
The rate of change for the interval between -6 and -3 on the x-axis is -2. Therefore, option A is the correct answer.
From the given graph, we have the coordinates (-6, 6) and (-3, 0).
Here, rate of change = (y₂-y₁)/(x₂-x₁)
Now, (0-6)/(-3+6)
= -6/3
= -2
Therefore, option A is the correct answer.

Can someone please explain why x= -2! ASAP!!
9514 1404 393
Answer:
x = -2 because that is the value that makes the equation true
Step-by-step explanation:
Minus signs are everywhere. They can all be eliminated by multiplying both sides of the equation by -1.
-1(-x -6 -x) = -1(-2)
(-1)(-x) +(-1)(-6) +(-1)(-x) = 2 . . . . . distribute the -1
x + 6 + x = 2 . . . . . . . . simplify
x + x + 6 = 2 . . . . . . . . rearrange
(1 +1)x +6 = 2 . . . . . . . . factor, using the distributive property
2x +6 = 2 . . . . . . . . . . . simplify
2x +6 -6 = 2 -6 . . . . . . subtract 6 from both sides
2x = -4 . . . . . . . . . . . . . simplify
(2x)/2 = (-4)/2 . . . . . . . divide both sides by 2
x = -2 . . . . . . . . . . . . . . simplify
x is -2 because that is the value we get when we apply the properties of equality to the equation. We can check to see if it works in the original equation.
Check
-x -6 -x = -2
-(-2) -6 -(-2) = -2 . . . . put -2 where x is
2 -6 +2 = -2 . . . . . . . . simplify the signs
-4 +2 = -2 . . . . . . . . . . add the first two terms (could do all at once)
-2 = -2 . . . . . . . . yes, the value of x=-2 makes the equation true

Additional comment
The properties of equality we're concerned with here are the multiplication property of equality, the addition property of equality and the division property of equality. Respectively, these tell us that multiplying, adding, or dividing both sides of the equation by the same number doesn't change the value of the variable.
These properties are essential to understanding how algebra works.

Given f(x) = 2x^2+ kx – 9, and the remainder when f(x) is divided by x + 6 is
57, then what is the value of k?
Given:
The function is
[tex]f(x)=2x^2+kx-9[/tex]
The remainder when f(x) is divided by x+6 is 57.
To find:
The value of k.
Solution:
According to the remainder theorem, if a polynomial function f(x) is divided by (x-a), then f(a) is the remainder.
The remainder when f(x) is divided by x+6 is 57.
Using remainder theorem, we get f(-6)=57.
Putting x=-6 in the given function.
[tex]f(-6)=2(-6)^2+k(-6)-9[/tex]
[tex]57=2(36)-6k-9[/tex]
[tex]57=72-6k-9[/tex]
[tex]57=63-6k[/tex]
On further simplification, we get
[tex]6k=63-57[/tex]
[tex]6k=6[/tex]
[tex]k=\dfrac{6}{6}[/tex]
[tex]k=1[/tex]
Therefore, the value of k is 1.

Answer:
Assuming you're referring to the sides of a right triangle, the missing side X would be 12.
Step-by-step explanation:
The Pythagorean Theorem states that the two legs of a right triangle squared and added together is equal to the hypotenuse squared. [tex]13^{2}[/tex] is 169, [tex]5^{2}[/tex] is 25, 169 - 25 = 144. Take the square root of 144 and you'll get 12, which is the missing side of the right triangle.
