2x+6=2(x+3)
Step-by-step explanation:
let x represent the unknown number
Answer:
48 oz.
Step-by-step explanation:
1lb is 16 oz.
You multiply 3 by 16 and that gives you 48
3 x 16 = 48
Answer:
For a function f(x), a vertical stretch of scale factor K is written as:
g(x) = k*f(x)
And for a function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N
If N is positive, the translation is up
if N is negative, the translation is down.
1) We have the function:
y = f(x) = 5^(x - 2)
A vertical stretch of factor 3 will be:
y = g(x) = 3*f(x) = 3*(5)^(x - 2)
2) We have the function:
y = f(x) = 7.2^x
A translation up of 8 units will be written as:
y = g(x) = f(x) + 8 = 7.2^x + 8
Start by finding the slope of the line by doing m(slope)=y2-y1 over x2-x1 using the pairs and then plug in the y and x of one of the points into the equation y=mx+b (y in the y and x in the x spot) and solve for b. Then plug the slope (can be a fraction shouldn’t be decimal) and y-intercept (b) back in the equation of a line above and you have your answer!
Answer:
x = 3
Step-by-step explanation:
<u>Step 1: Plug in 12 for y</u>
<em>2x - 18 = -2(12) + 12</em>
<em />
<u>Step 2: Multiply</u>
<em>2x - 18 = -24 + 12</em>
<em />
<u>Step 3: Combine</u>
<em>2x - 18 = -12</em>
<em />
<u>Step 4: Add 18 to both sides</u>
2x - 18 + 18 = -12 + 18
<em>2x = 6</em>
<em />
<u>Step 5: Divide both sides by 2</u>
2x / 2 = 6 / 2
<em>x = 3</em>
<em />
Answer: x = 3
