Yo get a perpendicular line you have to have the reciprocal of the slope, in this case the slope is -2/5 so the reciprocal is 5/2. You then plug the coordinates in for y and x with the slope you found to find b (or the y-intercept). The equation will be 2=-6(5/2)+b. Solve and b=17. The final equation is y=(5/2)x+17
If Maya only has $15 dollars to spend and she buys a notebook for $5.50 then that leaves her with $9.50 and if she has to save $7.75 then that leaves her with $1.75 and since she wants to buy cookies then you have to figure out how many cookies she can get with $1.75 plus the tax but food doesn't have tax so she can buy 7 packages of cookies since there only 25 cents is right on point at $1.75 I hope I answered your question with all the calculating I had to do and the typing I went through to explain it to you !!!!!!!!!!!!!!!!!!!!!!!! now could you please give me a thank you and hit the brain aster button please and thank you so much
if you do !!!!!!!
Answer:
186 pounds
Step-by-step explanation:
volume : base area × height
area of rectangular triangle : a×b/2
Vp = (5.5 × 12 / 2) × 7.5 = 33 × 7.5 = 247.5 ft³
the weight of the contents : 247.5 × 0.75 = 185.625 pounds
= 186 pounds (rounded)
Answer:
4(3+6)= (4*3)+(4*6)
Step-by-step explanation:
Distributive property is distributing a number in th brackets.
Hello,
xC+yH2SO4->xCO2+ySO2+zH2O
for H: 2y=2z==>y=z
for O:4y=2x+2y+z ==>2y=2x+z
Let's
z=t
y=t
2x=t or x=y/2
We suppose t=2
z=2
y=2
x=1
==>C+2H2SO4->CO2+2SO2+2H2O
