Answer:
x+y=4
Step-by-step explanation:
No solution means that the lines will never intersect. We know that the slope of line A is -1, and it's y intercept is 2. If you look at the last option for the answer choices, it's slope is also -1, but it's y intercept is at 4. These lines have the same slope, also known as parallel, so they will never intersect, thus giving no solution
Answer:
47
Step-by-step explanation:
Answer:
They are, because similarity means that the ratio of the sides are equal and they are proportionate.
Step-by-step explanation:
If you look at the graph, you can count 2 units from the smaller diamond/rhombus to the other diamond/rhombus. If you count the amount of units on each side, you will find that they are not equal, however they should be proportional if you calculate the angles of 90°.
Answer:
2 years
Step-by-step explanation:
Simple Interest formula is given as:
I = P × R × T
P = 640
I = 192
r = 15% = 0.15
Hence, to find time we use the formula
T = I/P × R
T = 192/640 × 0.15
T = 192/96
T = 2 years
Therefore, it will take 2 years .
Given:
Height of Isabelle = 62 inches
Shadow of Isabelle = 93 inches
Shadow of tree = 279 inches
To find:
The height of the tree.
Solution:
Let height of tree be x.
Ratio of height to shadow for Isabelle and tree are
The shadow of Isabelle and tree are proportional to their shadows. So, both ratios must be equal.
Multiply both sides by 279.
Therefore, the height of tree is 186 inches.
