Answer:
Step-by-step explanation:
I'm doing seven.
<em><u>x = -2</u></em>
y = 2^(-2 -1) + 2
y = 2^(-3) + 2
y = 1/2^3 + 2
y = 1/8 + 2
y = 2.125 which is a guess on the graph.
<em><u>x = - 1</u></em>
y = (2)^(-1 -1) + 2
y = (2)^-2 + 2
y = 1/4 + 2
y = 2.25
x = 0
y = 2^(0 - 1) + 2
y = 2^(-1) + 2
y = 1/2 + 2
y = 2.5
<em><u>x = 1</u></em>
y = 2^(1 - 1) + 2
y = 2^0 + 2 If the power of a number = 0 then the result = 1. The only exception to that is 0^0
y = 1 + 2
y = 3
Eight
<em><u>x = -1</u></em>
y = (1/2)^(-1 + 1) + 2
y = 1 + 2
y = 3
<em><u>x = 0</u></em>
y = (1/2)^(0 - 1) + 2
y = (1/2)^-1 + 2 Turn the 1/2 upside down
y = 2 + 2
y = 4
<em><u>x = 1</u></em>
y = (1/2)^(1 + 1) + 2
y = (1/2)^2 + 2
y = 1/4 + 2
y = 2.25
<em><u>x = 2</u></em>
y = (1/2)^(2 + 1) + 2
y = (1/2)^3 + 2
y = 1/8 + 2
y = 2.125
Step-by-step explanation:
Length of the plastic cube (L) = 12 cm
Volume of the cube
= L³
= ( 12)³
= 1728 cm³

Answer:
2.25 x 10
Step-by-step explanation:
In the above question, we were given :
The weight of the Elephant = 9 × 10³ pounds
The weight of the African Lion = 4 × 10² pounds
We would compare both weights to determine which size is bigger
Weight of Elephant : Weight of Lion
9× 10³ : 4 × 10²
= 9 × 10³/4 × 10²
= 2.25 × 10¹
= 2.25 × 10
The weight of the elephant is 2.25 × 10 times greater than the weight of the lion.
Answer:
x=√3
Step-by-step explanation:
Let's solve your equation step-by-step.
3x2+3x−2=3x+7
Step 1: Subtract 3x from both sides.
3x2+3x−2−3x=3x+7−3x
3x2−2=7
Step 2: Add 2 to both sides.
3x2−2+2=7+2
3x2=9
Step 3: Divide both sides by 3.
3x2
3
=
9
3
x2=3
Step 4: Take square root.
x=±√3
x=√3 or x=−√3
8) y=4x+6
The slope is 4 and the y-intercept is 6
4x-y=-6
-y=-4x-6
y=4x+6
