Answer:
4=7/4*4-3
Step-by-step explanation:
Since the equation for a line is <em>y=mx+b </em>(where <em>m </em>is the slope and <em>b </em>is the y-intercept), we can fill in part of the equation with the coordinates. So far we have- <em>4=m4+b. </em>We can then add the slope into the equation, turning it to <em>4=7/4*4+b. </em>To find the y-intercept, you replace <em>x </em>with zero and solve for <em>y. So, </em>lets multiply <em>7/4 </em>and <em>4 </em>and simplify the equation to <em>4=(7*4)/4+b.</em> Next, we'll simplify the right side, turning the equation to <em>4=7+b. </em>Now, all we have to do is subtract <em>7 </em>from the right side of the equation, leaving us with the result of <em>b=-3.</em> We'll add that into our equation now, giving us our answer of 4=7/4*4-3
Parent functions are the most basic functions you can find. Familiarity with the basic characteristics of these simple graphs will help you analyze the shapes of more complicated graphs. So the <em>Parent Absolute Value Function</em> is given by:
This function is shown in the figure below. As we can see, the
domain of this function is the set of all real numbers while the
range is:
1) Let's solve this system. We can start by rewriting it this way:
Let's pick the 3rd equation and isolate x, from it:
2) Now, we can plug that into the first and the 2nd equation.
Now let's solve this system to find y
Now, let's find y based on y=-z+2 plug into that z=3
2.2) And finally, let's find x
Hence, the answer is:
Answer:
- C) Use benchmark percent and find 50% of 146.7
Step-by-step explanation:
<u>Accurate estimation of 33% of 146.7</u>
A) Round the percent and find 30% of 146.7
- Acceptable, rounded down the %
B) Round the number and find 33% of 150
- Acceptable, rounded up the number
C) Use benchmark percent and find 50%
of 146.7
- NOT acceptable as 50% is too much for 33%
D) Round the percent and number and
find 30% of 150
- Acceptable, both % and the number rounded
E) All of them would be an accurate estimation
