Answer:
The product is 8.25
Step-by-step explanation:
Let
x-----> one number
y ----> the other number
I assume x>y
x-y=4 ----> equation A
x+y=-7 ---> equation B
Solve the system by elimination
Adds equation A and equation B
x-y=4
x+y=-7
-----------
2x=-3
x=-1.5
Find the value of y
x-y=4
-1.5-y=4
y=-1.5-4=-5.5
The numbers are -1.5 and -5.5
Find their product
(-1.5)(-5.5)=8.25
Answer:
a) Neither arithmetic nor Geometric
Explanation:
Since 99-89.9= 9.1, and 89.9 - 78.8 = 11.1, the sequence is not arithmetic.
Like wise 89.9/99=0.908 and 78.8/89.9 = 0.876 makes it not a geomtric sequence
Step-by-step explanation:
Answer:
93
<u>Step-by-step:</u>
86 + 7 = 93
<u>The 24 denominator stays the same and just add the numerators:</u>
+ 
= 93
*also 14 + 13 does not equal 24, its just closest to one of the choices*
Answer:
B) Likely
Step-by-step explanation:
Unlikely = < 50%
Likely = > 50%
Certain = 100%
Equally likely = 50%
Answer:
yes
Step-by-step explanation:
A quadratic function has the general form
fx) = ax² + bx + c ( a ≠ 0 )
f(x) = x² - 2x + 3 ← is in this form and is a quadratic function
