Answer:
30 (.1)=3
or you could do
30×.1=3
you could use either one but I dont know what the person your turning the work in requires the equation to look like
Jose buys cookies and lemons at the store. He pays a total of $30.64. He pays $5.20 for the cookies. He buys 6 bags of lemons that each cost the same amount. Which equation could be used to determine x, how much each bag of lemons costs?
Answer:
$4.24 each
Step-by-step explanation: I did the math. Well but you first subtract the amount of the cookies. Then you have to divided to est of it by six then boom you get the answer.
The distance between Point A (a, b) and Point C (c,d) can be found by using which formula?​
Answer:
d = √[(a-c)^2 + (b-d)^2]
solve by substitution.
5x-3y=-4
x+y=-4
Answer:
x=-2,y=-2
Step-by-step explanation:
x+y=-4
x=-4-y--(3)
substitute (3) in (1)
5(-4-y) -3y=-4
-20-5y-3y=-4
-8y=16
y=16/-8
y=-2
substitute y in (3)
x=-4-(-2)
x=-2
y + 4 ≤ |x-2|
please explain how to solve and graph it. Also please show a graph.
| = an absolute value bar, it kinda looks like 1
Answer:
y ≤ |x - 2| + 4
Step-by-step explanation:
step (1)
move the 4 to the other side, so it would look like:
y≤ |x-2| + 4
step (2)
now we can start graphing it, you would first start on the x axis moving it to the right. so your point on the graph should be (2,0) {don't graph a point there though}
the reason we do this is because the absolute value means the opposite so everytime there is a number in the absolute value being added or subtracted by just x then we move it the opposite side.
then from that (2,0) we go up four which would now make it (2,4). that is our first point and vertex so graph that.
now in y≤ |x-2| +4 you have to note that if there is nothing next to the equality and the absolute value, then it will become a 1. so our equation will now look like y ≤ 1 |x-2| + 4. so with that from our (2,4) point, we go up one and to the right one and to the left one. So there should be two more points at (3, 5) and (1, 5).
we then keep following the pattern of going up one and the right one and to the left one. the graph line should be in a V shape.
step (3)
now there is one last thing you need to do which is shading. what you're going to do first is check the inequality sign. if the inequality sign has a line under it (meaning equal to) then the line will be a solid line. if it doesn't then there should be a dashed line. our inequality sign has a line under it so it is a solid line.
then we need to figure out where to shade, above or below. if the y is greater than the rest of the equation then that means you need to shade above the V shape. however, if it were to be less than the rest of the equation you would shade below the V shape.
in this problem since the y is less than the rest of the equation, shade downwards.
i hope this answered your question and sorry if my explanation was hard to understand, its a pretty lengthy and confusing but it was the only way i knew of how to explain :))

What kind of reward and sacrifices do you believe a doctor would have?
Answer:
As a doctor, you witniss pain and death on a daily basis (which can be tramatic). You also have peoples lives put in your hands, and if you fail them you must answer their legal caretakers and or family. Also lawyers in some cases. Law can be a con of being a doctor. It is easy to get a lawsuit against yourself in that job category. But the pros (good things) are that the pay is well, and if all goes right you get to save lives for a living. This job is also deemed a sophisticated one by most, gaining you scholarships, respect, etcetera.
What is the slope of a line which passes through points (-7,2) and (21,-10)?
The question gives us two points, (-7,2) and (21,-10), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (2 - (- 10)) ÷ (-7 - 21)
= - ¹²/₂₈
= - ³/₇
Checking my answer:
We can use the slope we found and a point to write the equation of a line. If the line passes through both points, then we calculated the slope correctly.
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y + 10 = - ³/₇ (x - 21)

What is the value of x?
Enter your answer in the box.
-3(3-10x) could you answer it quickly for me? please and thank you
It's distribute property.
Answer:
-9+30x
Step-by-step explanation:
-3 x 3 is -9
-3 x -10x is 30x
Answer:
-9 + 30x
Step-by-step explanation:
Like you mentioned, to solve this expression we need to use the distributive property...
We have to distribute -3 to 3 and -10x.
When multiplying negative and positive numbers it is important to know that...
-negative times negative equal positive
-negative times positive equal negative
-3 · 3 = -9
-3 · -10x = 30x
Therefore the answer is -9 + 30x
Hope this helps! Let me know if you have any further questions :D

The answer is 36.Write the equation of a line perpendicular to 5x−9y=−8 that passes through the point (−5,8).
Answer: y = -(9/5)x - 1
Step-by-step explanation:
Rewrite the equation in standard form: y = (5/9)x+(8/9). [y=mx+b]
A line perpendicular to this would have a slope that is the negative inverse of the original slope (5/9), which would make it -(9/5). The y-intercept would also change, but we don't know the value, yet. For now, we'll use "b" for the y-intercept. This results in a perpendicular line:
y = -(9/5)x + b
We can calculate b, the y-intercept, by using the point (-5,8) and solving for b.
8 = -(9/5)*(-5) + b
8 = (9) + b
b = -1
The line perpendicular to 5x−9y=−8 that passes through the point (−5,8) is
y = -(9/5)x - 1

The Hulk just flew into the Boston airport to visit some family, but due to car problems, they are
unable to pick him up. He only has $20 on him. He needs to call a cab that costs $1.75 initially and
$.65 per mile. How far will he be able to go? If his family lives 25 miles away, will the cab be able to
get him to his family?
Answer:
Yes, he will be able to afford 25 miles
Step-by-step explanation:
20.00 - 1.75 = 18.25
He will have $18.25 after the initial payment.
18.25 / 0.65 = 28~
He will be able to go 28 miles with the 18 dollars he has left.
