A pair of perpendicular lines intersect at the point (5,9). Write
the equation of the line that is perpendicular to the line that
also passes through the point (-4,4)

Answers

Answer:

The equation of the line that is perpendicular to the line that passes through the point (-4, 2) is y = -9·x/5 + 18

Step-by-step explanation:

The coordinates of the point of intersection of the two lines = (5, 9)

The coordinates of a point on one of the two lines, line 1 = (-4, 4)

The slope of a line perpendicular to another line with slope, m = -1/m

Therefore, we have;

The slope, m₁, of the line 1 with the known point = (9 - 4)/(5 - (-4)) = 5/9

Therefore, the slope, m₂, of the line 2 perpendicular to the line that passes through the point (-4, 4) = -9/5

The equation of the line 2 is given as follows;

y - 9 = -9/5×(x - 5)

y - 9 = -9·x/5 + 9

y =  -9·x/5 + 9 + 9

y = -9·x/5 + 18

Therefore, the equation of the line that is perpendicular to the line that passes through the point (-4, 2) is y = -9·x/5 + 18.

Answer:

a=3

Step-by-step explanation:

p(x)=x^2-x-6 and f(x)=x^2+3x-18

they have a common factor x=a

so, when they are devided by x-a leave 0 as the remainder ( by remainder theorem)

p(a) =0

f(a)=0

SO, p(a) =f(a)

a^2-a-6=a^2+3a-18

a^2-a^-a-3a= -18+6

-4a= - 12

a=3

What makes -36 in multiplication?

Answers

Answer:

Basically the factors of 36 but one number will be negative.

Step-by-step explanation:

negative number x positive number = negative number

-1 x 36 = -36

-2 x 18 = -36

-3 x 12 = -36

-4 x 9 = -36

-6 x 6 = -36

-9 x 4 = -36

-12 x 3 = -36

-18 x 2 = -36

Hope this helps :)

The presence value of a negative sign in the multiplication operation contributes to the final result being -36.

In multiplication, the value -36 can be obtained by multiplying a positive number by a negative number or by multiplying two negative numbers.

For example:

-36 = (-1) × 36

This means that multiplying -1 by 36 gives us -36.

Similarly:

-36 = 6 × (-6)

Here, multiplying 6 by -6 also results in -36.

Jenna feeds her cat twice a day. She gives her cat 3/4 can of cat food each time. Jenna is having a friend take care of her cat for 5 days. To prepare, she bought 8 cans of cat food. Did Jenna buy enough cat food? If so, how much? If not, how much did she have?

Answers

Given:

Number of times Jenna feeds her cat = 2

Cat food each time [tex]=\dfrac{3}{4}\text{ can}[/tex]

Number of days = 5

Number of cans she bought = 8

To find:

Did Jenna buy enough cat food.

Solution:

Required food for each time  [tex]=\dfrac{3}{4}\text{ can}[/tex]

Jenna feeds her cat twice a day.

Required food for a day [tex]=2\times \dfrac{3}{4}\text{ can}[/tex]

                          [tex]=\dfrac{3}{2}\text{ can}[/tex]

Required food for 5 days [tex]=5\times \dfrac{3}{2}\text{ can}[/tex]

                           [tex]=\dfrac{15}{2}\text{ can}[/tex]

                           [tex]=7.5\text{ can}[/tex]

Since, 7.5 cans < 8 cans, therefore, Jenna buy enough cat food for her cat.

Answer:

0.5x + 78.2 = 287

0.5x = 287 - 78.2

A box has four cards numbered 1 to 3 and four Hong will toss a coin wants and record the toss as heads or tails then he will randomly pick a card from the box and record the number chosen give the sample space describing all possible outcomes then give all of the outcomes for the event that the number chosen is three use the format H1 to mean that the coin tosses heads in the number chosen is one if there is more than one element in the set separate them with commas

Answers

Answer:

Sample Space = {H1, H2, H3, Hfour, T1, T2, T3, Tfour}

O(Card 3 Chosen) = {H3, T3}

Step-by-step explanation:

A sample space is the set containing all the possible outcomes or results that can occur during an event. In this case the sample space will contain 8 outcomes, and it will be as follows:

Sample Space = {H1, H2, H3, Hfour, T1, T2, T3, Tfour}

Now, it is clear from the sample space that there are total two outcomes in sample space, in which the card numbered 3 is chosen. They are:

O(Card 3 Chosen) = {H3, T3}

where, O represents Outcomes.

Christina took a total of 10 quizzes over the course of 5 weeks. How many weeks of school
will Christina have to attend this quarter before she will have taken a total of 18 quizzes?
Assume the relationship is directly proportional.
weeks
Submit
Work it out

Answers

Answer:

9 weeks

Step-by-step explanation:

If she took 10 quizzes over the span of 5 weeks, then she took 2 quizzes per week.

This is because:

10 quizzes ÷ 5 weeks = 2 quizzes

We can use this information to solve for 18 quizzes by setting up the equation the same way

If she takes 2 quizzes every week, and ends with 18 finished quizzes, how many total weeks did it take her ?

Variable x = total weeks

18 quizzes ÷ x weeks = 2 quizzes

With division, we can switch x weeks and 2 quizzes

18 quizzes ÷ 2 quizzes = x weeks

18 ÷ 2 = 9

9 weeks

i think you would add them than confine the number And after you combine ad and I should be your final answer that’s how I think I hope I could help

The quotient by dividing the given numbers is required.

The quotient is 0.44 x 10³.

Division

The given numbers are

4.29 x 10⁵

9.75 x 10²

Let us make the numbers into whole numbers

4.29 x 10² x 10³ = 429 x 10³

9.75 x 10² = 975

So,

(429 x 10³) ÷ 975 = (39 x 11 x 10³) ÷ (39 x 25)

= (11/25) x 10³

= 0.44 x 10³

Line fg goes through the points (4,9) and (1,3) which represents a line that is perpendicullar to fg and passes through the point (2,0)

Answers

Answer:c

Step-by-step explanation:

The equation of the perpendicular line is [tex]y = -\frac 12x + 1[/tex]

The points are given as:

[tex]F = (4,9)[/tex]

[tex]G = (1,3)[/tex]

Start by calculating the slope (m) of line FG as follows:

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

Substitute values for x's and y's.

So, we have:

[tex]m = \frac{9 -3}{4 - 1}[/tex]

[tex]m = \frac{6}{3}[/tex]

[tex]m =2[/tex]

The equation of the line is said to be perpendicular to line FG.

So, the slope of the line is:

[tex]m_2 = -\frac 1m[/tex]

This is then calculated as:

[tex]m_2 = -\frac 12[/tex]

The line is said to pass through point (2,0).

So, the equation of the line is:

[tex]y = m_2(x - x_1) +y_1[/tex]

This gives

[tex]y = -\frac 12(x - 2) +0[/tex]

Expand

[tex]y = -\frac 12x + 1 +0[/tex]

[tex]y = -\frac 12x + 1[/tex]

Hence, the equation of the line is [tex]y = -\frac 12x + 1[/tex]
