Answer:
The x - intercept of the line is (-4, 0).
Step-by-step explanation:
The <em>x</em>-intercept is the point from which the graph passes through the <em>x</em>-axis.
At the <em>x-</em>intercept y = 0.
The provided line is:
Substitute y = 0 in this equation to determine the <em>x</em>-intercept as follows:
Thus, the <em>x</em>-intercept is (-4, 0).
Refer to the graph below.
Answer:
A) reflection across the y-axis
Step-by-step explanation:
If , then this says that two
-coordinates are equal for opposite values of
.
Let a point on
.
Then .
We also know that and therefore
is also a point on the graph.
If you graph [/tex](-a,b)[/tex] and you will see they are symmetrical to each about the
-axis.
Example if given both and
, then
. This means both (2,3) and (-2,3) are points on the graph.
Here is what those two points look like on a Cartesian Plane (please see graph in picture).
Answer:
An egg and cheese biscuit was $3.65.
Step-by-step explanation:
Liam's breakfast was:
Where:
P: total price
E: egg
C: cheese biscuit
M: carton of milk
(1)
Now, Finn's breakfast was:
(2)
By subtracting equation (2) from (1) we have:
Hence, the price of a carton of milk is $2, so by entering this value into equation (1) we can find the price of an egg and cheese biscuit:
Therefore, an egg and cheese biscuit was $3.65.
I hope it helps you!
