what is the equation of the line that passes through the point (8,4) and has a slope of 3/2 ?
Answer:
y = 3/2x - 8
Step-by-step explanation:
y = 3/2x + b
4 = 3/2(8) + b
4 = 12 + b
-8 = b
Oliver spot frustrated sometimes with his somewhat limited set of red We, and green building bricks. Part way through project, he often machines that transform brick of one colour into a combination of cut of bricks of one particular colour. So he invented some 3D printing bricks of one or more colours, Ench machine can also operate in re The red machine (R) converts I red brick (r) into I blue brick (b) 1 groet brick (g). This process and its reverse are represented by R-1 R bg and be Similarly, for the blue machine (B) we have B B- b Tg and Tg +b. And for the green machine (G) we have G-1 g rb and rb The machines can be used on collections of bricks, performing one con version at a time. For example, 3 blue bricks can be converted into 1 red and 3 green bricks in three steps, as follows: B B G- bbb rgbbrgrgb rggg Note that the order of the bricks in each collection is irrelevant. a Show how Oliver can convert 1 red brick into 3 red bricks. b Show how Oliver can convert 1 red brick into 5 red bricks in six steps. c Explain why Oliver cannot convert 1 red brick into 5 red bricks in less than six steps. d Oliver starts with a collection of bricks in which the combined number of blue and green bricks is odd. Explain why he cannot end up with a combined number of blue and green bricks that is even

Step-by-step explanation:
The dollar value of a car is a function, f, of the number of years, t, since the car was purchased. The function is defined by the equation f(t)=12,000(3/4)^t.
A. How much was the car worth when it was purchased? Explain how you know.
B. What is f(2)? What does this tell you about the car?
C. About when was the car worth $6,000? Explain how you know.
Answer:
1.) 12000
2.) 6750
3.) 2.41
Step-by-step explanation:
Given the Equation :
f(t)=12,000(3/4)^t. ; where, t = time ; f(t) = worth of car at time, t
When, car was purchased, t = 0
t = 0
f(0) = 12000(3/4)^0
= 12000 * 1
= 12000
2.)
f(2) ; this mean the worth of the car after 2 years :
f(2)=12,000(3/4)^t.
12000(3/4)^2
12000 * 0.5625
= 6750
When car will be worth 6000
f(t) = 6000
f(t)=12,000(3/4)^t.
6000 = 12,000(3/4)^t
6000 / 12000 = (3/4)^t
1/2 = (3/4)^t
Take the log of both sides :
Log(0.5) = log(0.75)^t
log(0.5) = tlog(0.75)
- 0.301029 = - 0.124938t
t = - 0.301029 / - 0.124938
t = 2.4094
t = 2.41 years

c
9(3x + 6) and 28x + 54
d
5(6x + 7) and 30x + 35
Answer:
C
Step-by-step explanation:
C because 9(3x+6) equals to 27x+54.
Therefore 27x+54 does not equal to 28x + 54

Consider this equation: 0B = 21. Is the equation always false, no matter what value you give the variable? Justify your answer.
Answer:
because the variable is being multiplied by 0.
Step-by-step explanation:
the B in the equation is just a place holder for any number you can think of.
the problem with that is that any number times 0 will always give you 0, so the equation will look like this now
0 = 21
this equation is false because 0 is not equal to 21.
21 is equal to 21.

Answer:
2) Slope=10/3
Step-by-step explanation:
2. Use the equation y2-y1/x2-x1. In this line, I took the points (-4,-5) and (-1,5). Plug this into the equation to get 5--5/-1--4. Simplify this to get 5+5/-1+4. Simplify this to get 10/3. Therefore, the slope is 10/3
4. The equation is y=mx+b where m is the slope and b is the y-intercept. This means that the equation will be 8/3x-5.

he total cost of a vase of spring flowers at a flower shop depends on the number of flowers ordered. The vase costs $3, and each flower costs $2.50. Which equation can be used to findc,the total cost of the vase withfflowers?
Answer:
3+2.50x
Step-by-step explanation
x represents how many flowers you bought which you mulitply with 2.50 since each flower is 2.50 dollars. Then you add 3 since the cost of the vase is 3 dollars.
Joe's friends are going to climb a climbing wall and have invited Joe to go with them. Joe is afraid of heights and wants to know how high the climbing wall is before he climbs it. Joe is 5.5 ft tall and at 3:00 pm his shad is 2.75 ft long. At the same time, the shadow of the rock-wall is 35 ft long. How tall is the rock wall?
Answer:
Rock Wall Height = 70ft
Step-by-step explanation:
Joe's height = 5.5 ft , Joe's shadow height = 2.75 ft [At 3.30 pm]
At 3.30 pm , Joe's height : Shadow Radio = 5.5 : 2.75 = 2 : 1
So, Product real height : Shadow height = 2 : 1 [At 3.30 pm]
Rock wall shadow height = 35 ft long
As per Height : Shadow ratio = 2 : 1 . So, rock wall real height = 2 x shadow height = 2 x 35 = 70 ft long
