Decide whether each equation is true for all, one, or no values of x.
1) 6x - 4 = -4 + 6x
6x -6x = -4+4
0 = 0
ans - true
2) 4x -6 = 4x + 3
4x-4x = 3+6
0 = 9
Ans - false
3) -2x+4=-3x+4
-2x + 3x = 4 - 4
x = 0
ans - false

A rectangle is 6 feet long and 4 feet wide. If each dimension is increased by the same number of feet, a new rectangle is formed whose area is 39 square feet more than the area of the original rectangle. By how many feet was each dimension increased?
Answer:
Each dimension increased by 3 ft.
Step-by-step explanation:
Area of the original rectangle = 4 * 6 = 24 square feet
Increased dimension = x ft
New length = 6 + x
New width = 4 +x
New area = (6 + x)(4 +x) {Use FOIL method}
= 6*4 + 6*x + x*4 + x*x
= 24 + 6x + 4x + x²
= x² + 10x + 24
New area = 24 + 39
x² + 10x + 24 = 63
x² +10x + 24 - 63 = 0
x² + 10x - 39 = 0
x² + 13x - 3x - 3*13 = 0
x (x + 13) - 3(x + 13) = 0
(x + 13)(x -3) = 0 {Ignore x + 13, as it gives negative value}
x - 3 = 0
x = 3
Find the discriminant and determine the number of real roots for each equation. Show steps.
-9x^2 + x - 7 = 0
Answer:
0 real roots
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
Then the discriminant is
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real and distinct roots
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then the roots are not real
- 9x² + x - 7 = 0 ← is in standard form
with a = - 9, b = 1, c = - 7 , then
b² - 4ac = 1² - (4 × - 9 × - 7) = 1 - 252 = - 251
Since b² - 4ac < 0 then the equation has no real roots
solve for x: 3^(x+3)=9

what is the sum of the measures of the angles of a convex quadrilateral? will this property hold if the quadrilateral is not convex?
Answer:
The sum of the measures of the angles of a convex quadrilateral is 360° as a convex quadrilateral is made of two triangles. Yes, this property also holds true for a quadrilateral which is not convex. This is because any quadrilateral can be divided into two triangles.
Which of the following is a one-to-one functions?
Answer:
A function f : X → Y is said to be one to one (or injective function), if the images of distinct elements of X under f are distinct, i.e., for every x1 , x2 ∈ X, f(x1 ) = f(x2 ) implies x1 = x2 . Otherwise, it is called many to one function.
3.5 x 10^3 divided by 7 x 10^-2

Answer: 3.5 times 10^3 is the same as 3.5 times 1000 so you get 3,500 now 7 times 10^-2 is the same as 7 times 1/100 and you get 7/100 so now we can divide 3,500 divided by 7/100 and we get 50,000

if n is an integer, what is the sum of the next three consecutive even integers greater than 2n? a. 6n + 12 b. 6n + 10 c. 6n + 4 d. 6n + 8
Answer:
a) 6n + 12
Step-by-step explanation:
Next three consecutive integers are : 2n + 2 , 2n + 4 , 2n + 6
2n + 2 + 2n +4 +2n +6 = 2n+ 2n + 2n + 2 + 4 + 6
= 6n + 12
The functions g and h are given by g(x) = x + 1 and h(x) = x²
Find the values of x for which hg(x) = 3x² + x - 5
Answer:
x = - [tex]\frac{3}{2}[/tex] , x = 2
Step-by-step explanation:
To find h(g(x)) substitute x = g(x) into h(x) , that is
h(g(x))
= h(x + 1)
= (x + 1)²
= x² + 2x + 1
For h(g(x)) = 3x² + x - 5 , then
3x² + x - 5 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides
2x² - x - 6 = 0 ← in standard form
(2x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - [tex]\frac{3}{2}[/tex]
x - 2 = 0 ⇒ x = 2

Sophia bought a fish tank with the dimensions shown below.
Which is closest to the number of cubic FEET of water needed to fill the fish tank? Hint: There are 1,728 cubic inches in 1 cubic foot.
A
0.8 cubic feet
B
2.5 cubic feet
C
240.0 cubic feet
D
1,440 cubic feet
0.8 cubic feet is closest to the number of cubic feet of water needed to fill the fish tank.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
To find the number of cubic feet of water needed to fill the fish tank
we need to first convert the dimensions of the tank from inches to feet.
since the conversion factor between cubic inches and cubic feet is 1,728.
Length in feet = 20 inches ÷ 12 inches/foot
= 1.67 feet
Height in feet = 12 inches ÷ 12 inches/foot
= 1 foot
Width in feet = 6 inches ÷ 12 inches/foot
= 0.5 feet
The volume of the fish tank in cubic feet is:
Volume = length × height × width = 1.67 feet × 1 foot × 0.5 feet = 0.835 cubic feet
Hence, the number of cubic feet of water needed to fill the fish tank is 0.8 cubic feet, Option A is correct.

the function of C gives the percentage of homes using only cell phone service X years after 2004 explain the meaning of each statement.
1. C(10)=35
2. C(x) = 10
3. how is C(10) different from C(x) = 10?
Answer:
Step-by-step explanation:
1. C(10)=35 is the percentage of homes using only cell phone service 10 years after 2004, that is, after 2014.
2. C(x) = 10 is the percentage of homes using only cell phone service x years after 2004. We must find x.
