(f+g)(x)=f(x)+g(x)=(2x-6)+(4x+7)=6x+1
(f-g)(x)=f(x)-g(x)=(2x-6)-(4x+7)=-2x-13
(fg)(x)=f(x)×g(x)=(2x-6)(4x+7)=8x^2-10x-42
(f+g)(-2)=f(-2)+g(-2)=(2(-2)-6)+(4(-2)+7)=-11
Answer: 12 miles equals 1 inch
Step-by-step explanation:
Answer:
The methods of graphing a linear function is <u>slope & intercept, identifying the function, and plotting the points and drawing a line</u>.
<h2>
</h2>
Because this equation is in slope-intercept form, we can tell exactly how it will look by checking out 3 key points.
Leading coefficient: negative, or positive.
In this case, the leading coefficient is positive, which means that the slope will be going from bottom left to upper right.
Leading coefficient = slope
In this case, the slope is 4, or 4/1, so it will be at a steep incline.
Value of constant = y-intercept.
In this case, the y-intercept is -2, which will help us narrow down our choice.
<h3><u>After reviewing the three answer choices, the most likely selection will be A, as it seems to have a slope of 4, it is positive, and it has a y-intercept of -2.</u></h3>
Answer:
8¹
Step-by-step explanation:
The given expression is :
8 to the power 1.
We need to write it in exponential form.
If we write 10³, here 10 is base and 3 is exponent.
8 to the power 1 = 8¹
The base is 8 and exponent is 1.
Hence, the exponential form is 8¹.
