Answer:
b = [tex]\frac{1}{3}[/tex]a - 4[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Distribute 3 to the parentheses:
a - 7 = 3(b + 2)
a - 7 = 3b + 6
Subtract 6 from both sides:
a - 13 = 3b
Divide each side by 3:
[tex]\frac{1}{3}[/tex]a - 4[tex]\frac{1}{3}[/tex] = b
So, the equation rearranged is b = [tex]\frac{1}{3}[/tex]a - 4[tex]\frac{1}{3}[/tex]
How do I do this problem (similar right triangles) please explain how you did it!!
ASAP!!!
Answer:
by phythagoras theorem
(c+b)^2=(8)^2+(6)^2
(b+c)^2=64+36
(b+c)^2=100
b+c=√100
b+c=10.
by phythagoras theorem
(8)^2=(a)^2+(b)^2
64-b^2=a^2. {1}
by phythagoras theorem
(6)^2=(a)^2+(c)^2
36-c^2=a^2. {2}
In equation 1 and 2,
64-b^2=36-c^2
64-36= -c^2+b^2
28= b^2-c^2
28=(b+c)(b-c)
28=10(b-c)
b-c=28/10
b-c=2.8.
b+c=10
b-c=2.8
subtract both equations
c=3.6
option A is correct.
Prove the identity.
sin x(1 + cot^2x)=csc x
Please answer thank you
Answer:
0. If it's a horizontal line, then the slope if automatically 0. if the line went straight up the slope would be "no slope" or "unidentified" your problem has a horizontal line so the slope is 0

Math loversss. PLEASE, HELP.
Answer:
I can say Now it's a positive fuction so the answer choices B and D with the negative 1 is wrong, sense Y is = 0 since the slope goes through 0
Step-by-step explanation:
My guess is Most likely A Since C The slope is going left to right which is positive
Anna has a total of 36 goldfish in her aquarium, some are orange and some are black. The number of orange goldfish is 7 more than twice the number of black goldfish. Which system of equations below can be used to describe the number of black and orange goldfish in Anna's aquarium?
Answer:
x + y = 36.....Equation 1
x = 7 + 2y...... Equation 2
Step-by-step explanation:
Let the number of:
Orange goldfish = x
Black gold fish = y
Anna has a total of 36 goldfish in her aquarium, some are orange and some are black.
x + y = 36.....Equation 1
The number of orange goldfish is 7 more than twice the number of black goldfish.
x = 7 + 2y...... Equation 2
We can rewrite this as:
x - 2y = 7..... Equation 2
The system of equations below that can be used to describe the number of black and orange goldfish in Anna's aquarium is :
x + y = 36.....Equation 1
x = 7 + 2y...... Equation 2
I think it’s
X + y= 36
X - 2y= 7
I hope this helps you have a good day
two parallel lines are cut by a transversal as shown below. Suppose m<8=131. Find m<1 and m<3.
Answer:
m∠1 is 49° and m∠3 is 49°
Step-by-step explanation:
In the given figure
∵ There are 2 parallel lines
∵ A transversal cuts them
∴ ∠4 and ∠8 are corresponding angles
→ Corresponding angles are equal in measures
∴ m∠4 = m∠8
∵ m∠8 = 131°
∴ m∠4 = 131°
∵ ∠1 and ∠4 formed a pair of linear angle
∵ The sum of the measures of the linear angles is 180°
∴ m∠1 + m∠4 = 180°
→ Substitute ∠4 by 131°
∴ m∠1 + 131° = 180°
→ Subtract 131 from both sides
∵ m∠1 + 131 - 131 = 180 - 131
∴ m∠1 = 49°
∵ ∠1 and ∠3 are vertically opposite angles
∴ m∠1 = m∠3
∵ m∠1 = 49°
∴ m∠3 = 49°

Answer:
x = 2 and y = 5
Step-by-step explanation:
Given
x = y - 3.....i)
2x + 3y = 19.........ii)
Putting x = y - 3 in equation II)
2( y - 3 ) + 3y = 19
2y - 6 + 3y = 19
5y = 19 + 6
5y = 25
y = 25 / 5
y = 5
Now putting y = 5 in equation i)
x = 5 - 3
x = 2
Hope it will help :)❤
