<span>We know that p is the statement x = 4 and that q is y = -2 . Then we have that the statement "If x = 4 then y = -2" can be written as "if p then q" . Then we can represent "If p then q" as p ---> .</span>

Answer:

p → q

Step-by-step explanation:

Given :Let p: x = 4 Let q: y = −2

To Find:Which represents "If x = 4, then y = −2”?

Solution :

1. p ∧ q represents “p and q”

2.p ∨ q represents “p or q (or both)

3.p → q represents “if p then q”

4. p ↔ q represents “p if and only if q"

So, we can see that p → q represents “if p then q" represents "If x = 4, then y = −2”

Thus Option C is correct p → q

. Four friends ate dinner at a restaurant. The bill was $51.89. They also left a $9 tip. Approximately what percent of the total
Akimi4 [234]

Answer:

Approximately 17%

Step-by-step explanation:

To find what percent 9 is of 51.89, you have to divide 9 by 51.89.

9/51.89 is 0.17344...

Since they said approximately, you can round 0.17344 to 0.17, which is equal to 17%.

The diagram shows two straight lines. both lines intersect at point A.
Setler [38]

Following the graph as listed we can immidiately say that (1/2,-2) & (-2,-8) must be wrong. This can be seen by the fact that the line's don't intersect in quadrants 1 & 4. It also cannot be greater than -2 or y would not =-2. Thus it must be (-1/2,-2) or (-2,1/2) and because we know they don't intersect in quadrant two, t<u>he correct answer must be (-1/2,-2)</u>. So the last answer is correct for the intersection point.

<em>TLDR: (-1/2,-2) is the correct answer. </em>

Write a fraction that is less than 5/6 and has a denominator of 8
KatRina [158]
You'll want to make a common denominator with 6 and 8.
That denominator would be 24.
24/6=4 so you would have to multiply 5/6 by 4/4 to get 20/24.
Next, 24/8=3 so 1/8 could be multiplied by 3/3 to get 3/24.
Since 3 is less than 20, 1/8 is smaller than 5/6.

If you want the same numerator, 5/8 = 15/24. This would make 5/8 smaller than 5/6 as well.
The highest eighth you can go is 6/8 which is 18/24.
So you can use any numerator between 1 and 6 with a denominator of 8 to get a fraction smaller than 5/6.

Write a quadratic equation in standard form that has 5 3 and 7 3 as its roots. A) 9x2 − 36x + 35 = 0 B) 9x2 + 36x − 35 = 0 C) 9x
Serggg [28]

Answer:

Option A)

9x^2 - 36x + 35 = 0

Step-by-step explanation:

We are given the following in the question:

Roots of quadratic equation are:

\alpha = \dfrac{5}{3}, \beta = \dfrac{7}{3}

The sum of the roots and the product of the roots can be calculated as:

\alpha + \beta = \dfrac{5+7}{3} = 4\\\\\alpha\beta = \dfrac{5}{3}\times \dfrac{7}{3} = \dfrac{5}{9}

Standard form of quadratic equation:

x^2-(\alpha + \beta)x+\alpha\beta = 0

Putting values, we get,

x^2 - 4x + \dfrac{35}{9} = 0\\\\9x^2 - 36x + 35 = 0

is the required quadratic equation.

Thus, the correct answer is

Option A)

9x^2 - 36x + 35 = 0
