If the graph of the linear equation ax-8y=15 has an x-intercept at (3,0), then what is the value of a?
Answers
====================================
Work Shown:
Plug in (x,y) = (3,0)
ax - 8y = 15
a(3) - 8y = 15 .... replace x with 3
3a - 8(0) = 15 ... replace y with 0
3a - 0 = 15
3a = 15
a = 15/3
a = 5
The equation updates to 3x - 8y = 15.

1. What is the measure of ∠ABC?
Answers
Answer:
I thought ik but i dont good luck!
Step-by-step explanation:
Answer:
∠ ABC = 55°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ABD is an exterior angle of the triangle , then
6x + 5 = x + 45 + 3x
6x + 5 = 4x + 45 ( subtract 4x from both sides )
2x + 5 = 45 ( subtract 5 from both sides )
2x = 40 ( divide both sides by 2 )
x = 20
Then
∠ ABD = 6x + 5 = 6(20) + 5 = 120 + 5 = 125°
∠ ABD and ∠ ABC are adjacent angles and are supplementary, thus
∠ ABC = 180° - ∠ ABD = 180° - 125° = 55°

Vivienne has 5 pets, all of which are either birds or cats. Her pets have a total of 14 legs. Choose the system of equations that can be solved to find the number of birds that Vivienne owns, b, and the number of cats that Vivienne owns, e.
Answers
Answer:
the system of equations is
b + e = 5
2b + 4e = 14
and the solved system gets you to the conclusion that vivienne has 3 birds and 2 cats
Step-by-step explanation:
b is the amount of birds and e is the amount of cats so adding them together would give you 5, the total amount of pets. so this is the first equation:
b + e = 5
next, we know that birds have two legs and cats have 4, so those respective numbers times the amount of each animal will give you 14, the amount of legs. so the equation would be:
2b + 4e = 14
so the system of equations would be
b + e = 5
2b + 4e = 14
i wasnt sure if you also needed to solve it but here it is solved
b = 5 - e
2(5 - e) + 4e = 14
10 - 2e + 4e = 14
10 + 2e = 14
2e = 4
e = 2
so using subsitution you would get b by using the value of e in the first equation.
b = 5 - e
b = 5 - 2
b = 3
so vivienne has 3 birds and 2 cats.
The required number of birds and cats Vivienne have is 3 and 2 respectively.
What are simultaneous linear equations?Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Vivienne has 5 pets, all of which are either birds or cats.
Let the number of birds be x, and the number of cats be y,
x + y = 5, - - - - -(1)
Now, Her pets have a total of 14 legs. Since a bird has 2 legs and a cat has 4 lags
According to the question,
2x + 4y = 14 - - - - -(2)
Solving equations 1 and 2,
2x + 4 (5 -x) = 14
2x + 20 - 4x = 14
2x = 6
x = 3
Now,
3 + y = 5
y = 2
Thus, the required number of birds and cats Vivienne have is 3 and 2 respectively.

The area of a square depends on the length of its sides. Answer the questions below
regarding the relationship between the area of the square and the length of one side
of the square.
Answers
Answer:
The independent variable, x, represents the length of one side of the square, and the dependent variable is the the area of the square, because the the area of the square depends on the length of one side of the square.
A function relating these variables is D(x) = x^2.
So D(6) =36, meaning if 6 is the length of one side then 36 would be the area of the square.
Step-by-step explanation:
The question clearly stated that the area depends on the side length, making the side length the independent variable.
The formula for the area of a square is the side length squared.
