Answer: y = 4/3x

y = -3/4x + 1 ⇔ 3x + 4y - 4 = 0

have:

(d): perpendicular to 3x + 4y - 4 = 0

contains the point (9;12)

=> (d): 4x - 3y + 3.12 - 4.9 = 0 ⇔ 4x - 3y = 0 ⇔ y = 4/3.x

Answer:

y = (4/3)x

Step-by-step explanation:

You have to find the y-intercept, b. Do this by substituting in the x and y values into the equation:

12 = (4/3)(9) + b

12 = 12 + b

b = 0

So, y = (4/3)x

Hope that helps! :D

Answer:

Brett's statement is true

Step-by-step explanation:

A negative times a negative will always equal a positive number.

If you see two negative numbers being multiplied together, you can ignore the negative signs and treat them both like positive numbers.

-4 x -5 = 20

4 x 5 = 20

Elena and Jada are 25 miles apart when they start moving toward each other. Elena runs at a constant speed of 6 mph and Jada wal

Setler [38]

<u>Answer:</u>

The Time taken by Elena and Jade to meet up is 2.5 hours

<u>Explanation:</u>

Given,

Elena moves with a speed of 6mph while Jada walks at a speed of 4 mph

Also, Distance can be calculated by the formula

$Distance = Speed * Time$

To find out the Total speed, i.e., speed of both Elena and Jada as both of them are walking in opposite direction we should add the speed of both the persons, if in same direction we should subtract the values

Here it will be: $6 + 4$ = 10mph

Distance apart is given as 25 miles. Substituting the values,

$Distance = Speed * Time$

25 = $10 * time$

Time = 25/10

Time = 2.5 hour

Hence, It will take 2.5 hours to meet up.

(3.2x10^3) + (5.78 x 10^5) ?

meriva

Simple....

you have: $(3.2* 10^{3} )+(5.78* 10^{5} )$

Simplify....

$(3.2* 10^{3} )=3200$

and

$(5.78* 10^{5} )=578,000$

3,200+578,000=581,200

=581,200

Thus, your answer.
