The answer is D) All the steps and the answer are correct. :)
You can just solve using the steps to see if they are right. For example, is -1x17=-17? Yes.
Answer:
60 grams
Step-by-step explanation:
For these type of questions, we can equate the ratio with the actual amounts. We will let the quantity to find be an unknown variable, such as x. Then we equate the ratios, cross multiply, and use algebra to solve.
Let grams of zinc be "x", so we can write the ratios and actual amounts as:
Then we cross multiply and solve for x, what we want to find out. Shown below:
There are 60 grams of zinc.
in plain English to transform a variable to have a desired mean and a desired standard deviation simply take the z transform
Answer:
a. Graph 1 is y=2^x and Graph 2 is y=2x+1
b. The slope increases over time on Graph 1, and remains the same on Graph 2
c. Graph 1 is exponential (y=2^x) and Graph 2 is linear (y=mx+b)
Hope this helps!
Step-by-step explanation:
a: y=2* is exponential, so it is graph 1 (it makes a curve) y=2x+1 is linear (makes a line), and it has a slope of 2 and a y-intercept of 1, so y=2x+1 is graph 2!
b. slopes of Exponential Functions usually continue to increase (unless the number that is being affected by the exponent x is less than 1, in which they would continue to decrease), and linear functions have a set slope (m in y=mx+b)
c. Explanation is in the answer (it says to explain)
