Answer:
(-1, 9) (he x value is placed first).
Step-by-step explanation:
y = -3x + 6
y = 9
Substitute y = 9 into the first equation:
9 = -3(x) + 6
-3x = 9 - 6
-3x = 3
x = -1.
Answer:
1=5

Answer:
100 sq units
Step-by-step explanation:
hypotenuse of the right triangle is the length of the square and we can find it by using the Pythagorean Theorem:
6² + 8² = c²
c² = 36+64
c² = 100
c = √100
c = 10
Area of square = 10² = 1--
Answer:The number of text messages sent by his sister=162
Step-by-step explanation:
Step 1
The ratio of number of text messages sent by Lucas to the number of text messages sent by his sister =4 to 9= 4:9
Number of text messages sent by Lucas =72
Total ratio is given as 4+ 9= 13
Step 2
such that the total number of messages sent by Lucas and by his sister will be calculated as
Ratio of text messages sent by Lucas/ total ratio x Total messages = Number of text messages sent by Lucas . Let X = Total number of messages
4/13 x X = 72
X=72 x 13 / 4 =234
Therefore, The number of text messages sent by his sister= ratio of text messages sent by his sister/ Total ratio x Total number of messages =
9/13 X 234= 162 messages
They are already in greatest to least
