Number 17 please. Need to know how to take the info and make it into a slope intercept equation.
Answer:
y = 5x -15
Step-by-step explanation:
slope/y-int from = y =mx+b
slope = y2-y1/x2-x2
slope = 0--15 / 3-0
slope = 15 / 3
slope = 5
y-int = -15
y = 5x-15
The length of a rectangle is 6 inches longer than the width. The perimeter of the rectangle is eight times the width. What is the width of the rectangle?
Answer:
The width is 3 inches.
Step-by-step explanation:
First, let's identify our variables.
L=Length
W=Width
P=Perimeter
P=2W+2L
We know that L=W+6
We can substitute L for W+6, and we can substitute P for 8W, which gives us the equation:
8W=2W+2(w+6)
If you go through all the steps to isolate the variable W, you'll end up with W=3
How can we re-write the expression below into ""friendlier"" terms? 6 ∙ 29
Answer:
A. 6 ∙ (30 - 1)
Step-by-step explanation:
How can we re-write the expression below into “friendlier” terms? 6 ∙ 29
options:
A. 6 ∙ (30 - 1)
B. 6 ∙ (16 + 13)
C. 6 ∙ (19 + 10)
D. 6 ∙ (21 + 8)
Re-writing an expression in friendlier term means expressing the term using numbers that are closest to the expression.
Checking all options,
A. 6 ∙ (30 - 1)
Option A seems closer to 6 ∙ 29 because, 30 - 1 which is very easy to evaluate gives 29
Moreover, 29 is very close to 30
Compared to other options, which have values that requires more thinking in evaluation

An engineer is designing three triangular traffic signs with a computer program. The vertices of Sign A are located at (2, 2) , (2, 12) , and (17, 7) . The vertices of Sign B are located at (4,4),(11, 19) and (18, 4) . The vertices of Sign C are located at (4, 8), (24, 1) , and (24, 15) . Put the signs in order from largest to smallest perimeter. Sign A Sign B Sign C
Answer:
sign C, sign B, sign A
Step-by-step explanation:
Given the vertices of triangular post A as (2, 2) , (2, 12) , and (17, 7). Let us find the length of side of the post using the formula for calculating distance between 2 points using the formula:
D = √(y₂-y₁)²+(x₂-x₁)²
For the coordinate (2, 2) , (2, 12)
S₁ = √(12-2)²+(2-2)²
S₁ = √(10)²+(0)²
S₁ = √100
S₁ = 10
For the coordinate (2, 2) , (17, 7)
S₂ = √(7-2)²+(17-2)²
S₂ = √(5)²+(15)²
S₂ = √25+225
S₂ = √250
S₂ = 15.8
For the coordinate (2, 12) , (17, 7)
S₃ = √(7-12)²+(17-2)²
S₃ = √(-5)²+(15)²
S₃ = √25+225
S₃ = √250
S₃ = 15.8
Perimeter of sign A = S₁+S₂+S₃
Perimeter of sign A = 10+15.8+15.8
Perimeter of sign A = 41.6
FOR SIGN B with coordinate of vertices (4,4),(11, 19) and (18, 4)
For the coordinate (4, 4) , (11, 19)
S₁ = √(19-4)²+(11-4)²
S₁ = √(15)²+(7)²
S₁ = √225+49
S₁ = 16.6
For the coordinate (4, 4) , (18, 4)
S₂ = √(4-4)²+(18-4)²
S₂ = √(0)²+(14)²
S₂ = √196
S₂ = 14
For the coordinate (11, 19) , (18, 4)
S₃ = √(4-19)²+(18-11)²
S₃ = √(-15)²+(7)²
S₃ = √225+49
S₃ = 16.6
Perimeter of sign B = S₁+S₂+S₃
Perimeter of sign B = 14+16.6+16.6
Perimeter of sign B = 47.2
FOR SIGN C with coordinate of vertices (4, 8), (24, 1) , and (24, 15)
For the coordinate (4, 8) , (24, 1)
S₁ = √(1-8)²+(24-4)²
S₁ = √(-7)²+(20)²
S₁ = √49+400
S₁ = 21.2
For the coordinate (4, 8) , (24, 15)
S₂ = √(15-8)²+(24-4)²
S₂ = √(7)²+(20)²
S₂ = √49+400
S₂ = 21.2
For the coordinate (24, 1) , (24, 15)
S₃ = √(15-1)²+(24-24)²
S₃ = √(14)²+(0)²
S₃ = √196+0
S₃ = 14
Perimeter of sign C = S₁+S₂+S₃
Perimeter of sign C = 14+21.2+21.2
Perimeter of sign C = 56.4
Arranging in order from largest to smallest perimeter, Sign C(56.4), Sign B (47.2), sign A (41.6)

How much interest will the account earn over this period?
Answer:
3250
Step-by-step explanation:
Multiply 5,000 times 6.5 percent
5000 X 6.5% = 3250
Big money Bank has an offer for new customers and the interest earned by the account over a period of time will be 3250.
What is Simple Interest?Simple interest is a quick and straightforward approach to figuring out how much interest has accrued on a sum of money. Interest is always applied to the main sum, and there is a constant rate of interest applied during the course of the calculation.
According to the question, the given information in the question is,
Principle amount, P = $5000
Rate, R = 6.5% and,
Time, T = 10 years
Make use of the simple interest formula, SI= [tex]\frac{P*R*T}{100}[/tex]
SI = [5000 × 6.5 × 10] / 100
SI = 325,000 / 100
SI = 3250
Hence, the interest earned by the account in this period will be 3250.

Step 1: Write equation
2 + x = -7
Step 2: Solve for x
Subtract 2 on both sides: x = -9Step 3: Check
Plug in x to verify it's a solution.
Substitute: 2 - 9 = -7Subtract: -7 = -7A) vehicle 1 is traveling at greater speed
B) vehicle 2 is traveling at a greater speed
C) vehicle 1 and 2 are traveling at the same speed
D) there is not enough information to determine which vehicle is traveling at a greater speed
========================================================
Explanation:
Let's find the slope of the graph
m = (y2-y1)/(x2-x1)
m = (120-80)/(3-2)
m = 40/1
m = 40
Each time x goes up by 1, y goes up by 40.
Vehicle 1 travels 40 miles for each hour, ie, its speed is 40 mph.
-------------
Now find the slope of the table
m = (y2-y1)/(x2-x1)
m = (240-150)/(8-5)
m = 90/3
m = 30
Vehicle 2's speed is 30 mph.
We see that Vehicle 1 is traveling 10 mph faster compared to Vehicle 2.
Michael has 2 liters of a 10% solution. How much of a 17% solution would he need to add to get a 15% solution?
Answer:
5 liters
Step-by-step explanation:
Let x represent the number of liters of the 17% solution, and represent the percentages as decimal values:
0.1(2) + (0.17)(x) = 0.15(x + 2)
Simplify:
0.2 + 0.17x = 0.15x + 0.3
Solve for x:
0.17x = 0.15x + 0.1
0.02x = 0.1
x = 5
So, you would need 5 liters of a 17% solution to get a 15% solution
