Given
The equation,
9x - 5y = 29.
To find the value of y when x is 1.
Explanation:
It is given that,

That implies,
When x=1,

Hence, the value of y is -4.
Answer:
-3/4
Step-by-step explanation:
Answer: Second option.
Step-by-step explanation:
By defintion, a Quadratic function is a polynomial of degree 2 and it has the following form:

Therefore, the function given is Quadratic. This is:

The steps to find the roots (or the x-intercepts) of the function, are:
1. You must substitute
:

2. Now, you can factor the Quadratic equation. Choose two numbers whose sum is 6 and whose product is 9. Notice that:

Therefore, you will get a "Double root".
4. So the solution is:

Answer:
48% of 25 is 12.
Step-by-step explanation:
To find : what percent of 25 is 12?
Solution : Let x be the percentage of 25 which is 12
So, by the statement
x% of 25 = 12
Now, we have to calculate the value of x
Step 1- Write the expression

Step 2- divide 25 by 100

Step 3- Cross multiply

Therefore, 48% of 25 is 12.
Answer:
40°
Step-by-step explanation:
The circumference of a circle is equal to 360°
The arc AB is 180°, the arc AC is given as 100° so the arc CB is 80° and since <A is an inscribed angle it is equal to the half of the arc it sees
80 ÷ 2 = 40
