X- small y- big
y=3x-6
3y=4x+7
we have to solve this, i am going to set the eq equal to each other
3(y=3x-6) = (3y=9x-18)
we mult the top eq by 3 to set them equal since the right side is equal to 3y.
9x-18=4x+7
9x=4x+25
5x=25
x=5
plug back into eq y=3(5)-6 y = 9 x = 5
Answer:
x=11
Step-by-step explanation:
13×11+26=117
5×11+8=63
117+63=180
Answer:
388
Step-by-step explanation:
Answer:
L = 34 - 0.5d
21 feet
Step-by-step explanation:
The initial water level ; 34
the amount is rises per day; 0.5
"L" is the water level,
"d" is the days passed.
In order to find the water level, one will have to multiply the amount the water rises each day, by the days passed. Then one will have to subtract that from the initial water level, hence the equation formed is the following;
L = 34 - 0.5d
Substitute in 26 for "d", to solve for the water level after 26 days.
L = 34 - 0.5(26)
L = 34 - 13
L = 21
Write the equation of the line passing through the two points. Show that this line is perpendicular to the given line.
(4,1) and (6,-5) y=1/3x-7
(1,-6) and (3,-10) y=1/2x-5
Please help, we learned this today and I’m really confused. How do you do it?
