Answer:
Y= 1/3x-15
Step-by-step explanation:
-6=-3(-3)+b
-6= 9+b
subtract 9 on both sides
b= -15
Y= 1/3x-15
because its perpendicular the -3x become positive and reciprocal
Answer:
Y= 1/3x-15

Choose the rate that represents: 175 miles in 4 hour
Answer:
43.75 mph
Step-by-step explanation:
Divide 75 by 4 and divide 4 by 4 which gets the unit rate
The unit rate that represents 175 miles in 4 hours is 43.75 miles per hour.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, The distance covered in 4 hours in 175 miles.
We know, Distance = speed×time.
Therefore, 175 = 4×s.
s = 175/4.
s = 43.75 miles per hour.

Identify the slope and y-intercept for 2x + y = 3
Step-by-step explanation:
The formula for the slope is y=mx+b, where m is the slope and b is the y-intercept. Since 2 is being multiplied by x, that means it is the slope. The variable y is being added, so it has to be the y-intercept.
Answer:
2=slope & y-intercept=y
Answer:
the slope is -2 and the y-intercept is 3
Step-by-step explanation:
you can rearrange the equation into y=mx+b form which will be y = -2x + 3
the m in y=mx+b is the slope, which in this case is -2.
and the y-intercept is 3 bc is the only constant in the equation.

ANSWER THESE 2 QUESTIONS FOR 100 FLIPPING POINTS :DDDD
Answer:
43.5 cm² and 112 cm²
Step-by-step explanation:
Here the instructions aren't given what to do. So I am finding the area of the ∆s .
Area of first ∆ :-
A = 1/2 * b * h A = 1/2 * 14.5 cm * 6cmA = 3 × 14.5 cm²A = 43.5 cm²Area of second ∆ :-
A = 1/2 * ( sum of || sides) * h A = 1/2 * ( 9 cm + 19cm) * 8cm A = 4cm * 28cmA = 112 cm²Answer:
[tex] \displaystyle 3) \boxed{ \rm {43.5 \: cm}^{2} }[/tex]
[tex] \displaystyle 4)\rm \boxed{112 {cm}^{2} }[/tex]
Step-by-step explanation:
Question-1:we are given a triangle and we want to figure out the area of it Since we are given the base and the height we can consider the following formula
[tex] \displaystyle \frac{1}{2} bh[/tex]
from the triangle we can assume base and height as 14.5 and 8 respectively Thus substitute:
[tex] \displaystyle \frac{1}{2} (14.5cm)(6cm)[/tex]
reduce fraction:
[tex] \displaystyle (14.5cm)(3cm)[/tex]
simplify multiplication:
[tex] \displaystyle \boxed{ \rm {43.5 \: cm}^{2} }[/tex]
Question-2:our given shape is trapezoid
therefore recall that,
[tex] \displaystyle A _{ \text{trapezoid}} = \frac{a + b}{2} h[/tex]
from the shape we define that
[tex]a = 9[/tex][tex]b = 19[/tex][tex]h = 8[/tex]now substitute:
[tex] \displaystyle \rm A _{ \text{trapezoid}} = \frac{9cm + 19cm}{2} (8cm)[/tex]
reduce fraction:
[tex] \displaystyle \rm A _{ \text{trapezoid}} = (9cm + 19cm)(4cm)[/tex]
simplify addition:
[tex] \displaystyle \rm A _{ \text{trapezoid}} = (28cm)(4cm)[/tex]
simplify multiplication:
[tex] \displaystyle \rm A _{ \text{trapezoid}} = \boxed{112 {cm}^{2} }[/tex]

Step-by-step explanation:
cosA/1-sinA=1+sinA/cosA
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 ⇒ cos²x = 1 - sin²x
Consider the left side
[tex]\frac{cosA}{1-sinA}[/tex] ← multiply numerator/denominator by (1 + sinA)
= [tex]\frac{cosA(1+sinA)}{(1-sinA)(1+sinA)}[/tex] ← expand denominator using FOIL
= [tex]\frac{cosA(1+sinA)}{1-sin^2A}[/tex]
= [tex]\frac{cosA(1+sinA)}{cos^2A}[/tex] ← cancel cosA on numerator/ denominator
= [tex]\frac{1+sinA}{cosA}[/tex]
= right side , thus proven

s=sandwiches
4.5s+6 less than or equal to 50
The answer is s is less than or equal to 12
Step-by-step explanation:
Finding Inequality
1. we know everything costs 50 in total so that is on one side of the equal sign.
____=50
2. we know he already spent 6 dollars so the money he can spend is 6 dollars less.
____+6=50
3. Each sandwich costs 4.50 $ so how much money does he have left to spend? we figure that out by multiplying the price by the number of sandwiches.
4.5s+6=50
Solving
1. 4.5s-6=50
First use the addition property of equality and add 6 to both sides.
2. 4.5s=56
Then use the division property of equality and divide each side by 4.5
3. you get a decimal but since you can't buy half a sandwich the answer is
s is less than or equal to 12

Answer:
MAYBE D OR A
Step-by-step explanation:
SORRY IF THIS WAS NO HELP
Answer:
D is correct
Step-by-step explanation:
Because the x has the |x| surrounding it, that means that it is always going to be positive (i think) which explains why both -1 and 1 are selected; because they both equal 1.

In ΔHIJ, i = 9.2 cm, j = 1.4 cm and ∠H=84°. Find the length of h, to the nearest 10th of a centimeter
Answer:
9.2
Step-by-step explanation:
S.A.S.→Law of Cosines
a^2=b^2+c^2-2bc\cos A
From reference sheet.
h^2 = 9.2^2+1.4^2-2(9.2)(1.4)\cos 84
=84.64+1.96−2(9.2)(1.4)(0.104528)
Square and find cosine.
h^2 = 84.64+1.96-2.69265
h
2
=84.64+1.96−2.69265
Multiply.
h^2 = 83.90735
h
2
=83.90735
Add.
h=
83.90735
≈9.16≈9.2
The required measure of the length of h is 9.2 centimeters.
What are trigonometric equations?These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.
here,
Law of Cosines
In ΔHIJ, i = 9.2 cm, j = 1.4 cm and ∠H=84°
Following the cosine rule
a²=b²+c²-2bc×cos A
From given
h² = 9.2²+1.4²- 2(9.2)(1.4) × cos 84
h² = 84.64+1.96-2.69265
h² = 84.64+1.96 −2.69
h² = 83.9
h ≈9.2
Thus, the required measure of the length of h, to the nearest 10th of a centimeter is 9.2 centimeters.
