2b is basically 2 * b. When a number (called the coefficient) and a variable come together they multiply.
Answer:
14.2 Units
Step-by-step explanation:
The second shape is given to confuse you and is not actually necessary.
To work out the perimeter of an irregular shape you simply add up the lengths of each side. The shape you have here is an irregular quadrilateral as it has four corners and no recognisable/coarrale organisation.
1.4units + 2.2units + 4.5units +6.1units = 14.2 units.
I hope this helps :)
Answer:
B) y=3x+7.5
Step-by-step explanation:
The equation of the data in the table can be obtained by using any two points.
We will use points (3, 13) and (5,17)
<u>The slope - intercept form is: </u>
<u>We find the slope as:</u>
- m = (17-13)/(5-3) = 4/2 = 2
<u>The equation becomes:</u>
<u>To find the value of b, the y -intercept is:</u>
- 13 = 2*3 + b ⇒ b= 13 - 6 = 7
<u>So the equation is:</u>
<u />
<h3>Now let's compare this with the options</h3>
A) y = 2x + 8.5
- The slope is 2, and y- intercept is 8.5
- It has same slope and greater y-intercept
- Answer is <u>no</u>
B) y=3x+7.5
- The slope is 3, and y- intercept is 7.5
- It has greater slope and greater y-intercept
- Answer is <u>yes</u>
C) y=5x+6.5
- The slope is 5, and y- intercept is 7.5
- It has greater slope but smaller y-intercept
- Answer is <u>no</u>
D) y=10x+5.5
- The slope is 10, and y- intercept is 5.5
- It has greater slope but smaller y-intercept
- Answer is <u>no</u>
Answer:
1. No
2. No
3. No
4. No
Step-by-step explanation:
y=2 so you multiply your x by 2 and you should come out with your y
your y should be 1 * 2 = 2 but is 9 ---->for (1, 9)
your y should be -6 * 2 = -12 but is 2 ---->for (-6, 2)
your y should be 2 * 2 = 4 but is -8 ----->for (2, -8)
your y should be 0 * 2 = 0 but is -4 ----> ( 0, -4)
side note -I'm sorry if you get it wrong,hopefully it's right though.
Multiply -3 with -3 you will get positive 6
