Answer:
B
Step-by-step explanation:
y - y1 = m (x - x1)
y1 = 3
x1 = 5
m(the slope)= -12
You have to get t alone so you divide both sides by 8
7.2/8= 0.9 and 8t/8=t
T=0.9
Answer:
<em>4 of the conspiracy theories were true</em>
Step-by-step explanation:
<u>Percentages</u>
Phil read a book with 16 conspiracy theories, 75% of which were false. It means that 25% of them were true.
25% of 16 is 25 * 16 / 100 =400 / 100 = 4
Thus, 4 of the conspiracy theories were true
I will explain how to get the solution using the text and look at the image as well as I’m using it to explain my process.
Step 1: Write the equation for slope-intercept form which is y=mx + b
Step 2: FIND SLOPE. M means slope in mathematics and the formula for that is rise divided by run. Which actually means y2 - y 1 divided by x2 - x1. If you are wondering what those are, they are points in the graph. It doesn’t matter which point you choose but you’ll see which ones I chose in the image. Follow the steps there
Step 3: FIND Y INTERCEPT: this step is easy because you are provided with a graph so you don’t have to find the y intercept algebraically. The y intercept is where the graph touch’s the y axis. In your case, it is at -4.
Step 4: CREATE THE EQUATION.
Refer to step one and re write the equation for slope intercept form: y=mx + b. Replace m with -2 and b with -4. So your equation looks like this: y= -2x -4
