Answer:
a) Эx ∈ R ⊇ x³ = 2
b) ∀x ∈ R, x² ≥ 0
c) Эx ∈ R ⊇ x³ = x
d) ∀x ∈ R, x ≤ x²
Step-by-step explanation:
Given the data in the question;
let us first go through some symbols and their possible meanings;
Э ⇒ there exists
∀ ⇒ for all
∈ ⇒ belongs to or set membership or element of the set
⊇ ⇒ such that
now;
a) There is a number whose cube is equal to 2
let x represent the number; so
Эx ∈ R ⊇ x³ = 2
b) The square of every number is at least 0
x² ≥ 0, ∀x ∈ R
∀x ∈ R, x² ≥ 0
c) There is a number that is equal to its square
Эx ∈ R ⊇ x³ = x
d) Every number is less than or equal to its square.
x ≤ x², ∀x ∈ R
∀x ∈ R, x ≤ x²
Answer:
(a) A and B are similar but not congruent
Step-by-step explanation:
All of the rectangles have sides in the ratio of 2:1, so are all similar. Only the rectangles that are the same size are congruent: A and C.
A and B are similar, but not congruent.
Point form: (-3,6)
Equation form: x=-3, y=6
To do this, we need to divide 4/1 by 1/2. When dividing fractions we multiply the first fraction by the reciprocal of the second fraction.
=
The answer is 8.

The gradient of the line 3y-12x+7=0 is; 4.
According to the question;
- We are responsible to determine the gradient of the line 3y-12x+7=0.
To do this; we must rewrite the equation 3y-12x+7=0 in the slope-intercept form as follows;
By comparison with; y = mx + c;
where, gradient/slope is m;
The gradient/slope of the line 3y-12x+7=0 is; 4.
