Red oak trees grow at a rate of about 2 feet per year. You buy and plant two red oak trees, one that is 6 feet tall and one that is 8 feet tall. The height h (in feet) of the shorter tree can be modeled by h=2t+6 where t is the time (in years) since you planted the tree. The height of the taller tree can be modeled by h=2t+8.
A. Graph both equations in the same coordinate plane.
B. Use the graphs to find the difference of the heights of the trees 5 years after you plant them. What is the difference after 10 years? What do you notice about the difference if the heights of the two trees?
Answer:
A: I think it's A because you need to graph both equations
Answer:
These are the screenshots of the work I did and more of the actual answer for graphing but basically,
The difference in heights of the trees after 5 years is 2 feet, after 10 years is 2 feet, and after any number of years is 2 feet since the lines are parallel.

Which is the equation of the line, in point-slope form, that has a slope of 2 and
passes through the point (4, -7)?
y+7= 2(x-4)
y-7 = 2(x+4)
x-7 = 2(x-4)
y-4 = 2(x+7)
Answer: y+7 = 2(x-4)
Step-by-step explanation: Point slope form is y − y1 = m(x − x1), where m is the slope and (x1,y1) is one known point on the line. We are told that m= 2 and (4,-7). Therefore:
(y − (-7)) = 2(x − (4))
y+7 = 2(x-4)
Cat food costs $2.85 for five cans. Ben only wants to buy one can. How much will it cost?
Answer:
$0.57 for each can of cat food
Step-by-step explanation:
2.85/5 = 0.57 giving you the answer
Answer:
it would cost 0.57 cents!
Explanation:
you'd have to divide 2.85 by 5, because if it is that much for 5 cans, and he only wants to buy 1, you'd divide it by 5, to get 0.57 :)

5. Rewrite the quadratic funtion from standard form to vertex form.
Ax) = 2x2 + 8x + 70
Answer:
[tex]y = 2 {(x + 2)}^{2} + 62[/tex]
Step-by-step explanation:
vertex form is
[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]
our original equation
[tex]2 {x}^{2} + 8x + 70[/tex]
first we will find the x value using the formula
[tex]x = - \frac{b}{2a} \\ - \frac{8}{2(2)} = - \frac{8}{4} = - 2 \\ x = - 2 = h[/tex]
plug the value of x back into the original equation to solve for y
[tex]y = 2 {x}^{2} + 8x + 70 \\ y = 2 ({ - 2}^{2} ) + 8( - 2) + 70 \\ y = 2(4) - 16 + 70 \\ y = 8 - 16 + 70 \\ y = 78 - 16 \\ y = 62 = k[/tex]
substitute this back into our vertex form and not forgetting the coefficient a = 2
[tex]y = 2 {(x - ( -2))}^{2} + 62 \\ y = 2 {(x + 2)}^{2} + 62[/tex]

Answer:
X=7
Step-by-step explanation:
These are supplementary angles. So they measure to 180º. 180º-95º=85º. 85º-10= 84º. 84º÷12x= 7.
Answer:
12x+1°+95°=180° (int angles)
12x+96°=180°
12x=180°-96°
=84°
x=84÷12

work out the value of x. 3x? x?
Answer:
x = 67.5
Step-by-step explanation:
Exterior angles always add up to 360 degrees. We have a defined right angle which takes 90 off of our 360, giving us 270 degrees. If we have x as an individual angle and also as x 3 times, then x is appearing 4 times. To find x, we divide our 270 degrees by 4 to get 67.5 . We can check this using a reversive property by multiplying 67.5 by 4 and then adding 90.
360 - 90 = 270
270 / 4 = 67.5
67.5 = x

In the above figure, m∠P = 130° and m∠Q = (5x)°. If angles P and Q are supplementary angles, what are the value of x and the measure of angle Q?
A.
x = 62, m∠Q = 50°
B.
x = 44, m∠Q = 220°
C.
x = 10, m∠Q = 50°
D.
x = 10, m∠Q = 15°
Answer:
C x = 10 Q = 50
Step-by-step explanation:
supplemantary means adds to 180 deg.
so 130 + 5x = 180
5x = 50 = ang. Q
x = 50/5 = 10 deg.
Sally's Soda company makes $1.20 for each can of soda sold out of a machine. If the company makes $144, how many
cans of soda were sold?
Answer:
120 cans of soda were sold
Step-by-step explanation:
Sally's Soda company makes $1.20 for each can of soda sold out of a machine. If the company makes $144, how many
cans of soda were sold?
144 ÷ 1.20 = cans sold
144 ÷ 1.20 = 120

120 x 1.20 = 144
The deer population is estimated to be 17,600 in northern
Illinois, but an actual count was 21,300. What is the percent
error?
The percentage error in the deer population is 17%
Actual population = 21300
Estimated population = 17600
The percentage error will be calculated by subtracting the estimated population from the actual population and then dividing the result. This will be:
= (Actual population - Estimated population) / Actual population × 100
= (21300 - 17600) / 21300 × 100
= 3700/21300 × 100
= 0.17 × 100
= 17%
Therefore, the percentage error in the deer population is 17%
