Let Q(x, y) be the predicate "If x < y then x2 < y2," with domain for both x and y being R, the set of all real numbers.

Levart [38]

Answer:

a) Q(-2,1) is false

b) Q(-5,2) is false

c)Q(3,8) is true

d)Q(9,10) is true

Step-by-step explanation:

Given data is $Q(x,y)$ is predicate that $x$ then $x^{2}$ . where $x,y$ are rational numbers.

a)

when $x=-2, y=1$

Here $-2$ that is $x$ satisfied. Then

$(-2)^{2}$

$4$ this is wrong. since $4>1$

That is $x^{2}$ $>y^{2}$ Thus $Q(x,y)$ $=Q(-2,1)$ is false.

b)

Assume $Q(x,y)=Q(-5,2)$ .

That is $x=-5, y=2$

Here $-5$ that is $x$ this condition is satisfied.

Then

$(-5)^{2}$

$25$ this is not true. since $25>4$ .

This is similar to the truth value of part (a).

Since in both $x$ satisfied and $x^{2} >y^{2}$ for both the points.

c)

if $Q(x,y)=Q(3,8)$ that is $x=3$ and $y=8$

Here $3$ this satisfies the condition $x$ .

Then $3^{2}$

$9$ This also satisfies the condition $x^{2}$ .

Hence $Q(3,8)$ exists and it is true.

d)

Assume $Q(x,y)=Q(9,10)$

Here $9$ satisfies the condition $x$

Then $9^{2}$

$81$ satisfies the condition $x^{2}$ .

Thus, $Q(9,10)$ point exists and it is true. This satisfies the same values as in part (c)

How do you divide fractions the way they taught it on 7th grade math edgenuidy * sorry I spelt it wrong it wouldn’t let me spell

Aleksandr [31]

Answer:

I'm old and the way I was taught about fraction division was:

INVERT AND MULTIPLY.

SO: (5/8) divided by (1/4) equals

(5/8) multiplied by (4/1) which equals (20/8) or 2.5

Write an equivalent exponential equation for the following three problems.

Naily [24]

<u>Answer with step-by-step explanation:</u>

We are given three different expressions and we are to write an equivalent exponential equation for them.

We know that the standard form of a logarithmic expression is given by:

$y = log_a ( x )$ which is equivalent to the exponential form $x = a ^ y$ .

1. $log _ {10} (0.1) = -1$ ---> $10^{-1}=0.1$

2. $log _ {3} 9 = 2$ ---> $3^2=9$

3. $log _ 5 ( \frac { 1 } { \sqrt { 5 } } ) = -\frac { 1 } { 2 }$ ---> $5^{-\frac{1}{2} }=\frac{1}{\sqrt{5} }$

Use the function f(x) = −16x2 + 60x + to Completely factor f(x). <br>Pls include steps

Elodia [21]

Answer: -4x(4x - 15)

Step-by-step explanation:

f(x) = $-16x^{2}$ + 60x

y = $-16x^{2}$ + 60x

=> - ( $16x^{2}$ - 60x)

=> -4x(4x - 15)
