The value a is 7.
<h3>What is Straight Line?</h3>
A line is simply an object in geometry that is characterized under zero width object that extends on both sides. A straight line is just a line with no curves.
Here, the given equation of line
y = ax -3
line passing through point (2, 11), then
11 = a X 2 - 3
11 + 3 = 2a
2a = 14
a = 7
Thus, the value a is 7.

He isn’t correct because both 0.4 and 0.400 is the equivalent number
Answer:
The x-intercepts will be, x= 7 or x =9
Step-by-step explanation:
f(x)= x^2 -16x+63
At the x-intercept, f(x) is zero.
Therefore;
x² - 16x + 63 = 0
solving it quadratically;
product = 63
Sum = -16
x² - 9x - 7x + 63 = 0
x(x-9) - 7( x-9) = 0
(x-7) (x-9) = 0
x = 7 or x = 9
Therefore;
The x-intercepts will be, x= 7 or x =9
Answer:
x = 0
Step-by-step explanation:
add 23 on both side and x equals zero
substitute x for 0, and the equation is still correct
