Answer:
0.4375
Step-by-step explanation:
In order to easily discern which graph is a proper representation of 6x + 4y = 8, you first need to convert the equation to y = mx+ b, also known as slope-intercept form. Here's how you can do this:
6x + 4y = 8
4y = -6x + 8
y = -1.5x + 2
The +2 tells you that your line will intercept the vertical y-axis at (0, 2). This narrows it down to graphs a and d. Then, because you have a NEGATIVE number in front of your x (it's -1.5), you can tell that your graph will be going down as it moves from left to right. This leaves you with graph d as your answer!
Answer:
The required equation is : 5 · 4000 = 20,000
Step-by-step explanation:
We have to use multiple of 10 for at least one factor.
So, in order to form our equation, we take one factor as 4000 which is a multiple of 10 (10 × 400 = 4000)
And the other condition to form the equation is given that the product should contain 4 zeros, so we need to multiply the first factor 4000 by some number such that the product contains 4 zeros.
Therefore, if we multiply 4000 by 5 we get the product as 20000 which contains 4 zeros.
Hence, 5 × 4000 = 20,000 is our required equation.
Answer:
C, D
Step-by-step explanation:
This equation can be solved any of several ways. One that doesn't require much thought is using the quadratic formula.
For ax² +bx +c = 0, the solutions are ...
In the given equation, a=2, b=11, c=5, so this becomes ...
The solutions are ...
C. x = -5
D. x = -1/2
_____
My personal favorite is using a graphing calculator. The solutions are the x-intercepts of the expression on the left. That is, where its value is zero, as the equation says.
