Answer:
y=7
Step-by-step explanation:
x = -1 x is one , replace x with negative one in the equation. using the order of operation PEMDAS.
Remember this -1³= -1×-1×-1=-1
-1²=-1×-1=1.
y =8x³+12x²-6x-3
y= 8(-1)³+12(-1)²-6(-1)-3
<h3>Exponents</h3>
y= 8(-1)+12(1)-6(-1)-3
<h3>Multiplication</h3>
y= -8+12+6-3
<h3>Addition</h3>
y= 10-3
<h3>Subtraction</h3>
y= 7
<h3>Therefore y= 7</h3>
Answer:
4 feet
Step-by-step explanation:
the 9 part of the ratio relates to 18 feet , then
18 ÷ 9 = 2 feet ← value of 1 part of the ratio , then
2 parts = 2 × 2 feet = 4 feet ← length on scale drawing
Answer:
A=B
Step-by-step explanation:
If AUB=A∩B then both A and B contain the values both have hence they're equal
<h3>
Answer: Movie B</h3>
Range = max - min
Visually the min and max are the leftmost and right most points on the whiskers. This is assuming we don't have outliers in either direction. The range represents the total width of the box and whisker plot. For movie B, it is wider, so therefore it has a larger range of ages.
We could compute the ranges numerically and compare to see which is bigger, or we could align one endpoint (say the right endpoints) to see that movie B has a wider range.
