What is the point-slope form of a line?If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).
The data points given are:
(1,2.5), (2,4.2), (4.5,6), (6,7), (8,8.1), (10,11)
Note that the growth seems to be linear, therefore, find a linear equation for the data.
Use (1,2.5) and (2,4.2) to find the slope of the line:
m = (4.2-2.5)/(2-1)
m = 1.7
The equation of the line with slope m = 1.7 and passes through point (1, 2.5) is:
y - 2.5 = 1.7(x - 1)
y = 1.7x - 1.7 + 2.5
y = 1.7x + 0.8
Substitute x = 3 into the above equation:
y = 1.7(3) + 0.8
y = 5.9
Hence, the distance run on day 3 is about 5.9 miles.

Answer:
22 degrees
Step-by-step explanation:
The total degree of a triangle is 180 degrees.
we are given two degrees already; 90 degrees (from the right angle sign) and 68 degrees from the problem. If we create an equation to reflect this we can find the missing angle:
180 = 90 + 68 + x
180 = 158 + x
x = 22

how are the particles in a solid piece of ice organized
Answer:
The particles in most solids are closely packed together and do not move around. ... Ice is different from most solids because its molecules are not packed as closely together as they are in liquid water. This means ice takes up a little more space than the same amount of liquid water. This is why ice floats.

Step-by-step explanation:
Zoey made 9 1/2 cups of trail mix for a camping trip. She wants to divide the trail mix into 3/4-cup servings. Thirteen people are going on the camping trip. Can Zoey make enough 3/4-cup servings so that each person on the trip has one serving?
Answer:
Zoey cannot make enough 3/4-cup servings so that each person on the trip has one serving.
Step-by-step explanation:
Zoey made 9 1/2 cups of trail mix for a camping trip.
She wants to divide the trail mix into 3/4-cup servings.
Thirteen people are going on the camping trip.
This means :
1 person = 3/4 cup servings
13 people = x
Cross Multiply
13× 3/4
= 39/4
= 9 3/4 cup
So for Zoey to be able to serve 13 people the trail mix in 3/4 cup servings, she need 9 3/4 cups of the trail mix
From the she made 9 1/2 cups of the trail mix.
Hence, Zoey cannot make enough 3/4-cup servings so that each person on the trip has one serving.

Answer:
the y axis will be 1 and the x axis will be 8
I know that the y axis will be 1 because y=1 and I know that the x axis will be 8 because 2 to cubed will be 8 because when you multiply 2 by 2 you get 4 and when you multiply 4 by 2 the answer will be 8 so the axis will be (1,8)

what is the equation of the line perpendicular to y=1/2x-3 going through the point P(10,5)?
Answer:
y=-2x+25
Step-by-step explanation:
the slope has to be -2, becauze in perpendicular lines, the slopes are opposite.
put it into y-y1=m(x-x1) form, which is y-5=-2(x-10)
then get rid of the parenthesis by distribution, which gives you y-5=-2x+20 (-10x-2 gives a positive 20)
then isolate y and balance the equation.
y-5+5=-2x+20+5, which gives you
y=-2x+25
Suppose y varies directly with x and y =75 when x = 6. What is the value of y when x = 5?
Answer:
62.5
Step-by-step explanation:
y∞x
y=kx( where k is the constant)
75=6k
75÷6 =k
12.5=k
therefore the relationship between k,x and y is y=12.5x
y=12.5×5
y=62.5

1: Write an equation of the line that passes through the points (−2,−7) and (0,−4).
2:Write an equation of a line that passes through the point (2,1) and is perpendicular to the line y=13x+2.
3:You have an initial amount of $55 in a savings account and you deposit an equal amount into your account each week. After 6 weeks the account holds $133. Write an equation that represents the amount y (in dollars) of money in the account after x weeks.
Answer:
1: y=(3x/2)-4 2 :y=(-x/13)+(15/13) 3: y = 13x+55
Step-by-step explanation:
1:
Begin by finding slope
m = (y2-1)/(x2-1)
(-7-(-4)/(-2-0) = 3/2
next use point slope form
y-y1 = m(x-x1) (you can pick any point to use, I will use (0,-4)
y-(-4) = 3/2(x-0)
y+4 = 3x/2
y=(3x/2)-4
2:
The slope of the line y=13x+2 is 13
Take the opposite sign and reciprocal of 13 to get the slope of the line perpendicular; in this case it's -1/13
Next, just like in problem 1, use point slope form.
y-1 = (-1/13)(x-2)
y-1 = (-x/13)+(2/13) (convert 1 to 13/13 for like terms and bring over to the left side)
y=(-x/13)+(15/13)
3:
the intercept will be $55 since it's the initial amount
you know that you deposit some amount every week so set this up as an equation
$133 = m(6)+$55 (the amount deposited every week times 6 +the initial $55 will equal $133)
solving for m gets you $13
so the equation is y = 13x+55
plug in 6 for x to check; 13x6 + 55 = 133
hope this helps
