Let blueberry = b and poppyseed = p
b + p = 64
b = p + 20
p + 20 + p = 64
2p + 20 = 64
2p = 44
p = 22
b = 22 + 20
b = 42
Jack bought 42 blueberry muffins
Answer:
Parallel is undefined
Perpendicular is 0
Step-by-step explanation:
The line x = -42 is a vertical line through the x-axis. As such its slope is undefined. All parallel lines have the same slope and will also be undefined. Perpendicular lines will be lines horizontal through the y-axis. This means the slope of any perpendicular line to it will be 0.
The sequences that would map the triangles so as to support both claims are explained below:
<em>Transformation</em> is a process in which the dimensions, size or orientation of a given shape is <em>adjusted</em>. The types are: translation, reflection, rotation and dilation.
Thus;
A. The sequence of transformations that will <u>support</u> Tim's thinking are:
i. <em>Reflection</em> of triangle A <em>about</em> the y-axis.
ii. <em>Reflection</em> of the triangle the <em>second</em> time now about x-axis.
iii. <em>Translation</em> of the triangle two units to the right (i.e towards the x-axis)
These steps would map triangle A unto triangle B supporting Tim's claim.
B. The sequence of transformations that will <u>support</u> Jennifer's claim are:
i. First <em>rotate</em> triangle A by
using the origin of the axis as the reference point.
ii. Then <em>translate</em> triangle A two units to the right (i.e towards the x-axis).
Therefore, these steps will map triangle A unto B to support Jennifer's claim.

A & B are composite while C is prime
Answer:
7ab - 5a
Step-by-step explanation:
For addition and subtraction this type of variable we should always keep one thing in mind that, we can only add or subtract only those digits whose variables are the same.
Solving given equation step to step:
(2ab - 5a - 7) - (-5ab - 7)
Opening the bracket first,
⇒ 2ab - 5a - 7 - (- 5ab) - (- 7)
⇒ 2ab - 5a - 7 + 5ab + 7
Now, taking same variables digits together
⇒ (2 + 5)ab - 5a - 7 + 7
⇒ 7ab - 5a - 0
⇒ 7ab - 5a
