the equations that will have only one solution are:
- 19x - 18 = -19x + 18 (option c)
- 19x + 18 = -19x + 18 (option d)
<h3>
When we have only one solution?</h3>
An equation of the form:
a*x + b = c*x + d
Has one solution only if a ≠ c.
With that in mind, we can see that the equations that will have only one solution are:
19x - 18 = -19x + 18 (option c)
19x + 18 = -19x + 18 (option d)
In the other two cases, the slopes of the linear equations are equal, so these equations have no solutions or infinite solutions.

Answer:
7
Step-by-step explanation:
When working with order of operations, use the acronym 'PEMDAS' (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
The equation should basically be done in that order.
There are no parenthesis,
no exponents,
But there IS multiplication.
1 x 10 = 10.
So now, what is left over is 10 - 3.
There addition, but there IS subtraction.
10 - 3 = 7.
7 is what is left over.
Therefore, 1 x 10 - 3 in standard form is 7.
Answer:
Step-by-step explanation:
Let the amount of flour left be .
Initial amount of flour = 18 cups
Cups used for 1 batch of muffins = 3
∴ Cups used for batches =
Amount left in the container is given as:
Therefore, the equation to show how much flour is left in the container after x batches of muffins is .
The graph of it is shown below.
Find the x and y intercepts and then join the line.
At x intercept,
So, x intercept is
At y intercept, ,
So, y intercept is
Join these two points to plot the graph.
