Answer:
Infinite Solutions
Step-by-step explanation:
Let's solve this equation my simplifying it so that we have x on one side.
Apply the distributive property on the right side:
[tex]7x - 14 = (7\cdot x) + (7\cdot -2)\\\\7x-14 = 7x-14[/tex]
Woah, that's strange. We have the exact same thing on both sides of the equation. This means there are infinite solutions. If we tried simplifying this, we'd just end up with 0 = 0.
Test it out! Any value of [tex]x[/tex] will work for this equation.
Hope this helped!
Solve the system of inequalities: a) .4x−1≤0
2.3x≥4.6
Answer:
(a) [tex]x \leq 2.5[/tex]
(b) [tex]x \geq 2[/tex]
Step-by-step explanation:
Solving (a):
[tex]0.4x - 1 \leq 0[/tex]
Add 1 to both sides
[tex]0.4x - 1 + 1\leq 0 + 1[/tex]
[tex]0.4x \leq 1[/tex]
Solve for x
[tex]x \leq 1/0.4[/tex]
[tex]x \leq 2.5[/tex]
Solving (b):
[tex]2.3x \geq 4.6[/tex]
Solve for x
[tex]x \geq 4.6/2.3[/tex]
[tex]x \geq 2[/tex]

The width of a rectangle measures 9.7 X -4.7 centimetersAnd the length measures 2.9 X +6.4 cm which expression represents the perimeter in centimeters of the rectangle
Answer:
25.2X + 3.4 centimeters.
Step-by-step explanation:
The formula for the perimeter of a rectangle
= 2L + 2W
= 2(L + W)
From the question:
Width of a rectangle (W) = 9.7 X - 4.7 centimeters
Length of a rectangle (L) = 2.9 X + 6.4 centimeters
Imputing it into the formula
2(L + W)
2( 9.7X - 4.7 + 2.9X + 6.4)
2 (9.7X + 2.9X - 4.7 + 6.4)
2( 12.6X + 1.7)
= 25.2X + 3.4 centimeters.
Therefore, the perimeter of the rectangle = 25.2X + 3.4 centimeters.

70 - 3 ____ 10 * (7 - 3)
67 ____ 10 * (7 - 3)
67 ____ 10 * 4
67 ____ 40
67 ≠ 40
Answer is ≠
this is because of the order you do a problem.
1. P - paranthesis
2. E - exponents
3. MD - multiplication division (whatever comes first)
4. AS - addition subtraction (whatever comes first)
There are no paranthesis in the first one so you multiply first.
There are paranthesis in the second one so you add first.
That gives you a different answer for each making it unequal.

Answer: N = 11
Step-by-step explanation:
Add 8 on both sides
-10n = -110
divide -110 by -10
Answer:
n = 11
Step-by-step explanation:
-10n - 8 = -118
Add 8 to each side
-10n - 8+8 = -118+8
-10n = -110
Divide by -10
-10n/-10 = -110/-10
n = 11

Answer: x=-7
Step-by-step explanation:
1) The angles of a triangle are equal to 180
2) Add your angles together and set them equal to 180 like this:
x+59+x+51+84=180
3) Combine like terms:
2x+ 194 =180
4) Subtract 195 from both sides:
2x+ 194 =180
- 194 -194
2x = -14
5) Divide by 2 on both sides
2x= -14

Alvin is 9 years older than Elga. The sum of their ages is 89. What is Elga's age?
Answer:
Alvin: 49
Elga: 40
Step-by-step explanation:
The equation is 89 = x + (x-9).Remove the parenthesis and combine the like terms. 89 = 2x - 9Add 9 on both sides. 98 = 2x Divide by 2 on both sides. x = 4949 is the age of Alvin. (49-9) 40 is the age of Elga.Hey there!☺
[tex]Answer:\boxed{40}[/tex]
[tex]Explanation:[/tex]
Elga's age can be represented as "x". If Elga is x years old, then Alvin's age would be represented as "x+9", since Alvin is 9 years older than Elga.
Their combined age is 89. If you were to write that as an equation in terms of "x", you would have the following equation.
[tex]x+x+9=89[/tex]
Since the question is asking for Elga's age, which is x, you're going to be solving the equation for the value of x.
First add like terms: [tex]x+x+9=89 \rightarrow 2x+9=89[/tex]
Subtract both sides by 9 to leave x alone: [tex]2x+9-9=89-9 \rightarrow 2x=80[/tex]
Divide both sides by 2 to find x: [tex]\frac{2x}{2} = \frac{80}{2} \rightarrow x=40[/tex]
Since x is equal to 40, Elga is 40 years old, and Alvin would be 49 years old.
You can also check if the answer is correct by adding their ages.
[tex]40+49=89\ \br \checkmark[/tex]
Elga is 40 years old.

On a coordinate plane, 2 lines are shown. Line P Q has points (negative 5, 3) and (5, 1). Line R S has points (negative 4, negative 2) and (0, negative 4).
Which statement best explains the relationship between lines PQ and RS?
They are parallel because their slopes are equal.
They are parallel because their slopes are negative reciprocals.
They are not parallel because their slopes are not equal.
They are not parallel because their slopes are negative reciprocals.
Given:
Line P Q has points (-5, 3) and (5, 1).
Line R S has points (-4, -2) and (0, -4).
To find:
The relationship between lines PQ and RS.
Solution:
If a line passing through two points, then the slope of line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Line P Q has points (-5, 3) and (5, 1). So, slope of line PQ is
[tex]m_1=\dfrac{1-3}{5-(-5)}[/tex]
[tex]m_1=\dfrac{-2}{5+5}[/tex]
[tex]m_1=\dfrac{-2}{10}[/tex]
[tex]m_1=\dfrac{-1}{5}[/tex]
Line R S has points (-4, -2) and (0, -4). So, slope of line RS is
[tex]m_2=\dfrac{-4-(-2)}{0-(-4)}[/tex]
[tex]m_2=\dfrac{-4+2}{0+4}[/tex]
[tex]m_2=\dfrac{-2}{4}[/tex]
[tex]m_2=\dfrac{-1}{2}[/tex]
Slopes of two parallel lines are equal.
[tex]m_1\neq m_2[/tex]
They are not parallel because their slopes are not equal.
Therefore, the correct option is C.

the correct answer is c
