what is the equation of the line with a slope of -3/4 that passes through the point (4,-2)?
Answer:
y=-3/4x+1
Step-by-step explanation:
y-y1=m(x-x1)
y-(-2)=-3/4(x-4)
y+2=-3/4(x-4)
y=-3/4x+12/4-2
y=-3/4x+3-2
y=-3/4x+1

The diagram shows a 6 ft student standing near a tree. The shadow of the student and the shadow of the tree ends at point A. What is the height of the tree?
Answer: 18ft
Step-by-step explanation: I took the quiz and got 100%
The height of the tree is 8.3 ft.
To solve this problem, we have to find the angle of elevation from the student.
To do this, we have to assume or bring out a right angle triangle and solve for the.
Given that we have the distance of A to F and the point to F
A to F = 5ftE to F = 6angle ?Trigonometric RatioUsing trigonometric ratio,
We can find the tangent of this angle
[tex]tan\theta = \frac{opposite}{adjacent} \\tan\theta = \frac{6}{5}\\ tan \theta = 1.2\\\theta = tan^-^1(1.2)\\\theta = 50.2^0[/tex]
The angle of elevation can be calculated using sum of angles in a triangle is equal to 180 degrees
[tex]180 = 90 + 50.2 + x\\x = 180- 140.2\\x = 39.8^0[/tex]
Assuming a right angle triangle from the point the student is standing, the distance from him to the tree would be
[tex]15 - 5 = 10ft[/tex]
Let's use the tangent of the angle to find the height of the tree.
[tex]tan\theta = \frac{opposite}{adjacent} \\tan 39.8 = \frac{x}{10}\\x = 10 tan39.8\\x = 8.3ft[/tex]
From the calculations above, the height of the tree is 8.3 ft.

Which equation represents the solution of the equation 6x – 18 = 30?
Answer:
x=8
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
6*x-18-(30)=0
STEP 1:
Pulling out like terms
Pull out like factors :
6x - 48 = 6 • (x - 8)
STEP 2:
Equations that are never true:
Solve: 6=0
This equation has no solution.
Solving a Single Variable Equation:
Solve : x-8 = 0
Add 8 to both sides of the equation :
x = 8

Tom has three times as many action figures as Jerry. If Tom has 27 action figures, how many does Jerry have? Write an equation that represents the scenario. Then solve.
Answer:
Jerry has 9 action figures.
Step-by-step explanation:
Since Tom has three times as many action figures as Jerry, Tom has 3x action figures, where x is the number of action figures that Jerry has.
Since Tom has 27 action figures, we can say that 3x=27.
3x=27
x=9

The ratio table shows the costs for different lengths of silver chain. Find the unit rate in dollars per inch
Length (inches) 16 18 20 22
Cost (dollars) $36.00 $40.50 $45.00 $49.50
The unit rate is $__ per inch.
Answer:
2.25
Step-by-step explanation:
yes
The unit rate of the silver chain is $0.44 per inch.
What is the unit rate?Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life.
Given here: 16 inches of silver chain costs $36 and 18 inches cost $40.50
Thus we have the unit rate( dollar/inch) =36/16=40.50/18=4/9
Therefore the unit rate is given by 4/9 or 0.444 dollar per inch.
Hence, The unit rate of the silver chain is $0.44 per inch.

th
term of the sequence 100, 20, 4, ....
Answer:
Step-by-step explanation:
a1 = 100
r = 1/5
an = 100 (1/5)^(n - 1)
Try it. We have the answer for a_3
a_3 = 100 * (1/5)^(3 - 1)
a_3 = 100 * (1/5)^2
a_3 = 100 * 1/25
a_3 = 4 which is just what the series says should be the answer.
