What is the slope and y-intercept of (5x-8y=3) Need help asap plz! thank you!

1 answer:

8 0

You can isolate y and you know that the slope is the number in front of x (the one that multiplies it) You know that the y-intercept is the value of y when x=0, therefore you can find y by replacing x with 0 in the equation 1-equation 5x-8y=3 5x=3+8y 5x-3=8y (5x-3)/8=y y=(5/8)x -3/8 (Slope = 5/8) 2- y-intecept (x=0) y=(5/8)(0)-3/8 y=-3/8

Answer:

A=4000, B=80, C=24

Step-by-step explanation:

You forgot to put the correct area model, I attached it to the answer.

We have the fact that Mountain Q is 4 times the height of Mountain P. That's the "4" we have in the left side of our model. It's like having a multiplication table, next to the "4" we have "A" and upper this we have "1000", the only thing we have to do is multiplify 4*1000=4000. The next letter we have is B and below it we have "320", we divided it by 4, 320/4=80. The last letter we have is C, and is below a "6", we only have to multiplify it by 4, 6*4=24.

At the end we only sum our
