None of those pairs can make this inequality true...

Answer:

All options are wrong.

Step-by-step explanation:

We have y > –3x + 3 and y > 2x – 2

Option A - (1,0)

y > –3 x 1 + 3 = 0

We have y = 0, which is not greater than 0.

Option A is not correct.

Option B - (–1,1)

y > –3 x -1 + 3 = 6

We have y = 1, which is not greater than 6.

Option B is not correct.

Option C - (2,2)

y > –3 x 2 + 3 = -3

We have y = 2, which is greater than -3.

y > 2 x 2 – 2 = 2

We have y = 2, which is not greater than 2.

Option C is not correct.

Option D - (0,3)

y > –3 x 0 + 3 = 3

We have y = 3, which is not greater than 3.

Option D is not correct.

All options are wrong.

Find the measure of angle K.

Alexus [3.1K]

Answer:

K = 97 degrees

Step-by-step explanation:

The four interior angles of a quadrilateral is always equal to 360 degrees.

127 + 88 = 215

(10x + 7) + (5x + 3) = 15x + 10

360 - 215 = 145

145 = 15x + 10

130 = 15x

9 = x

k = 10x + 7

k = 10(9) + 7

k = 97

Identify the values a, b, and c is the first step in using the quadratic formula to find the solution(s) to a quadratic equation

zlopas [31]

The values are a = 7, b = -9, c = -18.

Step-by-step explanation:

The given quadratic equation is $7x^{2} - 9x = 18$

The general form of the quadratic equation is $ax^{2} + bx + c = 0$

where,

a is the coefficient of x².
b is the coefficient of x.
c is the constant term.

Now, you have to modify the given quadratic equation similar to the general form of quadratic equation.

So, bring the constant term 18 to the left side of the equation for equating it to zero.

⇒ $7x^{2} - 9x - 18 = 0$

Compare the above equation with general form $ax^{2} + bx + c = 0$

⇒ a = 7

⇒ b = -9

⇒ c = -18

Therefore, the values of a, b, and c are 7, -9 and -18.

PLEASE HELP I WILL MARK YOU BRAINIEST PLEASE

cupoosta [38]

Answer:

Zeniab makes the most money by $0.25, and would make $2.50 more.

Step-by-step explanation:

Okay, the good news is, this problem is about finding how much you make in an hour.

Zainab makes $44 for 8 hours

and

Keziah makes $47.25 in 9 hours.

in each problem, we can set them up in an equation of

$44=8x

and

$47.25=9x

In the first equation, divide both sides by 8 to isolate the x.

that would be 44/8 = x which is $5.50 per hour for Zainab.

In the second equation, divide both sides by 9 to isolate the x.

That would be 47.25/9 = x which is $5.25 per hour for Keziah.

This means that Zainab would make more per hour, and to find the second part of the question for a 10 hour job,

(You can multiply any number by 10 easily by moving each number up one place. Hundreds go to the thousands when you multiply by 10 as an example. In this problem, 5.50 times 10 would be $55.00 because the 5 behind the decimal would be moved up infront of the decimal)

Zainab would make $55 for 10 hours

Keziah would make $52.50 for 10 hours

Then, take the difference of those final totals, which is $2.50, or multiply $0.25 by 10 to get $2.50

Find the equation of a line perpendicular to y-3x=-8 that passes through the point (3,2). Answer in slope-intercept form

Zielflug [23.3K]

Y - 3x = -8
y = 3x - 8...slope here is 3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -1/3.

y = mx + b
slope(m) = -1/3
(3,2)...x = 3 and y = 2
now we sub and find b, the y int
2 = -1/3(3) + b
2 = -1 + b
2 + 1 = b
3 = b

so ur perpendicular equation is : y = -1/3x + 3

If an experimenter sets equal to .01, then she is defining a "statistically rare" event as an event occurring more than one time

Fynjy0 [20]

Answer:

The correct answer is an event occurring one or fewer times in 100 times if the null hypothesis is true.

Step-by-step explanation:

For a statistically rare event, its probability is relatively small and the event is very unlikely to occur. Therefore, if an experimental sets equal to 0.01 which is statistically rare, then we can interpret this mathematically as:

p(event) = 0.01 = 1/100

where p(event) is the probability of the event.

In addition, statistically, null hypothesis signifies no major difference between the specified parameters, and any obvious difference that might occur as a result of experimental error. Thus, it can be concluded that the event is occurring one or fewer times in 100 times if the null hypothesis is true.
