3. y-intercept is when x=0, so 2. Slope is change in y divided by change in x, so 4/3, which rounds to 1.3.
4. the equation: y=mx+d, so substitute m for the slope and d as the y-intercept, so you get y=1.3x+2
5. When you look at the graph, when x=7, then y=80. So the student may get an 80.
Answer: 2 units.
Step-by-step explanation: When you graph the points given, it gives you this shape in the image below. The hypotenuse (longest side of triangle) is found by doing the following:
a^2 + b^2 = c^2, where a and b are the legs (the other sides of the triangle) and c is the hypotenuse.
5^2 + 2^2 = 29.
√ 29 ≈ 5.38, and that is the length of the hypotenuse.
The shortest side is the bottom side, which is 2 units. Therefore, that is your answer.
Let me know if this is right! :)
Answer:
there are 25 boys and 35 girls
Step-by-step explanation:
if you draw out 5 lines to represent the boys and 7 lines each to represent girls to equal enough to make 60 you need 5 times of this. 5x5=25 boys. 7x5=35 girls. 25+35=60
Answer:
4.4 x 10^9
Step-by-step explanation:
(8.8 x 10^6)(5 x 10^2)
Multiply the 8.8 and 5
8.8 x 5 = 44
Add the powers (don't touch the 10s)
6 + 2 = 8
Right now we have: 44 x 10^8 but this isn't in scientific notation. The decimal must have a SINGLE digit to the left of it; no more no less.
Move the decimal over one place to the left.
44 turns into 4.4
This action adds another power
8 + 1 = 9
Thus our final answer is: 4.4 x 10^9
