Kevin went to the nursery and bought a 5 ft tall tree. After planting the tree, Kevin made a table to record the
height, h, of the tree, t years after it was planted. Verbally describe the relationship between h and t.
t 0 1 2 3 4
h 5 6 7 8 9
3. By using the table in question 2, write an equation to illustrate the relationship between the height of the tree
and the number of years since it was planted. How tall will the tree be in 8 years?

Someone buys 6 cakes for 8$ each he sells them for ten each then he got 8 more and selled them for 10$ how much money does he have left???
Answer: $28
Step-by-step explanation:
The person bought 6 cakes for $8 which reduces his money by:
= 6 * 8
= -$48
He then sells them for $10 each so the money made was:
= 10 * 6
= $60
He then buys 8 more for the same price which will reduce his money by:
= 8 * 8
= -$64
He sells these 8 for $10 so the money made was:
= 8 * 10
= $80
Total money left is therefore:
= 60 + 80 - 48 - 64
= $28
Brianna used two congruent parallelograms and a square to create the figure.
What is the area of the figure Brianna created in square feet?
Answer Choices:
A: 27 ft²
B: 24 ¾ ft²
C: 67 ½ ft²
D: 33 ¾ ft²
Answer:
D. 33 3/4 ft²Step-by-step explanation:
The figure comprises of a square with side of 4 1/2 ft and two parallelograms with base of 4 1/2 ft and height of 1 1/2 ft
Total area is:
(4 1/2)² + 2(4 1/2)( 1 1/2) = (4 1/2)( 4 1/2 + 2(1 1/2)) = 9/2(9/2 + 3) = 9/2(15/2) = 135/4 = 33 3/4 ft²Correct option is D
Answer: the correct answer is d

-(7-9)z-6z=8(-6+2) solve for z
can I see the process I know the answer is 8 I just don't understand the process
Answer:
(-(7-9))(z)-6z= 8(-6+2)
Simplify
-(-2)(z) -6z =8(-6+2)
Multiply 8*-6 and 8*2
2z -6z= -48+16
Combine like terms
2z+-6z =-32
-4z=-32
Divide both sides by -4
z=8

50 points to whoever is right and brainliest. The graph shows a proportional relationship. Which equation matches the graph?
Answer:
B. y = 3xStep-by-step explanation:
Use one of the points on the graph to find the equation.
Let's take the point (1,3)
We know the proportional relationship is:
y = kx, where k is the coefficient of proportionalitySubstitute the values from the point and solve for k:
3 = 1*kk = 3The function is:
y = 3xCorrect choice is B
Answer:
The graph is in a proportional relationship (given)
Therefore, it is in the form y=kx where k is a constant.......(i)
Now in the graph we can locate that when the value of x is 1, the value of y will be 3
Putting the value of x and y in equation (i), we get
3=1×k
k=3
Now, putting the value of k in equation (i), we get
The equation of the graph is y=3x.
★ B. y=3x is the right answer.Find the amount of interest owned for a $1,895 loan for 4 years at a 7.9% interest rate

(2x - 3)²
Special cases
Answer:
4x²+12x+9
Step-by-step explanation:
1. 2x times 2x = 4x²
2. 2x times 3 = 12x
3. 3 x 3 = 9 or 3² also equals 9
ANYONE HELP PLEASE<3
Answer:
y = (2/3)x + 7
Step-by-step explanation:
Slope intercept form is y = mx +b
1) We start off with y =
2) m = slope. Since we know that the slope is 2/3 we can plug it in. y = 2/3x
3) b is y-intercept which = 7.
Put it all together: y = 2/3 x + 7
