Answer:
The slope would be 1/4.
Step-by-step explanation:
To find the perpendicular slope first you have to set this equation to y
to do this you use the subtraction prop of equality and you will get 12x-9= -3y
then you divide by -3 on both sides to get y by itself
you will get -4x+3=y
now that you know the slope is -4, you must find the negative reciprocal slope of this which means you have to flip the numerator and denominator and make the sign its opposite.
The perpendicular slope would then be 1/4.

7-6=1 but instead of putting the one there it would just be x depending on your teacher they'd mark it wrong if you put the 1.
A construction crew is lengthening a road. The road started with a length of 56 miles, and the crew is adding 4 miles to the road each day.
Let L represent the total length of the road in miles), and let D represent the number of days the crew has worked. Write an equation relating L to D. Then
use this equation to find the total length of the road after the crew has worked 34 days.
Equation:
D=
Total length of the road after 34 days: miles
х
5
?
Step-by-step explanation:
your equation.L = 56 + 4(D)
L = 56 + 4(34)
L = 56 + 136
L = 192
Total length of the road after 34 days is 192 miles

What is the slope of the line below? If necessary, enter your answer as a
fraction in lowest terms, using the slash (/) as the fraction bar. Do not enter
your answer as a decimal number or an equation.
(1,6) (-5,-7)
Answer:C. 13/6
Step-by-step explanation:
The slope is always rise over run. So when going from the coordinate (-5,-7) to the coordinate (1,6) we go up 13 then go to the right 6. And since we went up and to the right it is a positive slope.
Step-by-step explanation:
Given: ΔABC, AB=12, m∠A=60°,m∠C=45°, AB =8 Find the perimeter of ΔABC
Answer:
The perimeter of ΔABC is 43 units
Step-by-step explanation:
An illustrative diagram is shown in the attachment below.
To find the perimeter of the triangle, we will first determine the length of the unknown sides.
First, we can determine /BC/ using the Sine rule
From Sine rule
[tex]\frac{SinA}{a} = \frac{SinB}{b} = \frac{SinC}{c}[/tex]
∴ [tex]\frac{SinA}{a} = \frac{SinC}{c}[/tex]
In the diagram, [tex]a = /BC/[/tex] and [tex]c = /AB/ = 12[/tex]
m∠A=60° and m∠C=45°
∴ [tex]\frac{Sin60}{/BC/} = \frac{Sin45}{12}[/tex]
[tex]/BC/ = \frac{12 \times Sin60}{Sin45}[/tex]
[tex]/BC/ = 6\sqrt{6}[/tex]
To find /AC/, will first determine m∠B
m∠A + m∠B + m∠C = 180° (Sum of angles in a triangle)
60° +m∠B + 45° = 180°
m∠B + 105° = 180°
m∠B = 180° - 105°
m∠B = 75°
Also, using the sine rule
[tex]\frac{SinB}{b} = \frac{SinC}{c}[/tex]
From the diagram, [tex]b = /AC/[/tex]
[tex]\frac{Sin75}{/AC/} = \frac{Sin45}{12}[/tex]
[tex]/AC/ = \frac{12 \times Sin75}{Sin45}[/tex]
[tex]/AC/ = 6 + 6\sqrt{3}[/tex]
Now,
The perimeter of ΔABC = /AB/ + /BC/ + /AC/
= [tex]12 + 6\sqrt{6} + 6+6\sqrt{3}[/tex]
= 43.09 units
≅ 43 units
Hence, the perimeter of ΔABC is 43 units.
Answer:
Using the figure above, if AB = RT and ∠R = 70°, then ________.
ΔABC ~ ΔRTS
m ∠ S = 50°
ΔABC ≅ ΔRTS
m ∠ S = 60°

Answer:The answer is 14x-25=115 (B)
Step-by-step explanation:
he bought a certain amount of shirts, each being 14 dollars. So 14(how ever many shirts)- 25(the coupon) = Sales price
Answer:
b. 14x-25=115
Step-by-step explanation:
14 dollars each and 25 discount
the "each" here means the cost per cloth is 14, and total cost of the clothes Marco buy will increase depend on the amount of clothes.
Thus, it is 14x
The 25 discount represent that NO MATTER how many clothes Marco purchase, he only gets a discount of 25. It is a independent value.
Total clothes bought - discount = total amount of money spent.
Thus, it is 14x-25=115

Step-by-step explanation:
A company makes plastic beach balls with a radius of 2 inches. How many square inches of plastic does the company
need to make 10 beach balls? Use 3.14 for x and round to the nearest tenth.
Recall the formula SA - 48/?.
50.24 in 2
100.5 in 2
2512 in 2
5024 in 2
Answer:
502.4 in²
Step-by-step explanation:
Area of a sphere = 4 πr²
Plastic beach balls are spherical in shape.
Hence, the Area of a sphere = 4πr²
Where r = radius = 2 inches
π = 3.14
Hence, the area of one spherical ball =
4 × 3.14 × 2²
= 50.24 square Inches
For 1 spherical ball, 50.24 square inches of plastic is needed to make it.
How many square inches of plastic does the company need to make 10 beach balls?
Therefore,
1 spherical ball = 50.24 in²
10 spherical balls = x
Cross Multiply
x = 10 × 50.24 in²
x = 502.4 in²
Therefore, 502.4 square inches of plastic is needed by the company to make 10 beach balls.

What are the distinct features of rational function, rational equation and rational
inequality?
1. Rational Function
2. Rational Equation
3. Rational Inequality
Answer:
Step-by-step explanation:
Rational funtion is a function f(x) in form of f(x)=p(x)/q(x). where p(x) and q(x) are polynomials and q(x)≠0.
Example: f(x)= (2x- 4)/(5x-6)
Rational equation is an equation involving rational expressions.
Example: [5/(x-3)] ≥ (2/x)
Rational inquality is an inqualit involving rational expressions.
Example: (2/x) - (3/2x) = 45

12. Which speed is not equivalent to 55 mi/h?
a. 110 mi
2 h
b. 265 mi
6 h
c. 385 mi
7
h
d. 550mi
10 h
Answer:
265 miles per 6 hours
Step-by-step explanation:
Multiply 55 by 1, 2, 3, 4, 5 and so on, to get the speed per each of those hours.
55 x 2 = 110 miles per 2 hours
55 x 6 = 330 miles per 6 hours
55 x 7 = 385 miles per 7 hours
55 x 10 = 550 miles per 10 hours.
Answer choice b (265 miles per 6 hours) is not equivalent to 55mph.
I hope this helps!

Explain how to use the distributive property to find an
expression that is equivalent to 20 + 16.
Answer:
they are both divisible by 4
so you could write
4 (5 + 4)
Step-by-step explanation:
Answer:
First, I would find that the GCF of 20 and 16 is 4. Then, I would divide both 20 and 16 by 4. Last, I would use the distributive property to write the sum as 4(5 + 4).
