Multiply:
1.17 x 1.5 = 1.755
rounded to 2 places = 1.76 minutes
Devisor is the bottom number
hmm
11.75=11 and 3/4
so times it by 4 to clear denomenator
but do it by top and bottom
23.4/11.75 times 4/4=93.6/47
so times it by 4/4
Answer:
1. x² + 3x - 5 = 0
2. x² - x = 3 x + 7
4. 7x² + 14x = 0
Step-by-step explanation:
A Quadratic equation takes the form;
ax² + bx + c = 0
a, b, c are constants and a cannot be 0.
Options 1 fits this;
x² + 3x - 5 = 0
Option 2 fits this as well;
x² - x = 3 x + 7
x² -x - 3x - 7 = 0
x² - 4x - 7 = 0
Option 4 fits this as well if c = 0.
7x² + 14x + 0 = 0
Answer:
1
Step-by-step explanation:
Assuming, we want to find the value of 
Recall that: any non-zero number exponent zero is 1.
Using this property, we simplify our expression to
since 
Now using the property of exponents: 
This implies that:
The correct answer is 1
Answer:
y ≥ 2
Step-by-step explanation:
Range is the y-axis, so we have to look at the graph to find what numbers the line hits.
The line starts at y = 2 and goes up forever (the arrow indicates this), so that means that this line hits all y-values above 2.
Therefore the range is any y-value 2 or higher, so the answer is y ≥ 2.
