Answer:
A
Step-by-step explanation:
square: 10² = 100
Circle: π*5² = 3.14*25 = 78.5
In the squqre not in the circle: 100-78.5 = 21.5
To solve these you have to follow the orders of operation(BEDMAS), which means brackets, exponents, division, multiplication, addition, subtraction all in that order.
A) This is false. 7x6+4=46 and does not equal 7x10 or 70.
B) This is false as well. The answer haste be 19 and 16-(4+7) does not equal 19. You add up what is in the brackets first and then subtract.
This means that C and D have to be true.
C) 10+(6/3)=12
10+2=12 True
D) 2+5x7=37
2+35=37
Also true
Answer:
Slope = 2
Step-by-step explanation:
Do rise/run, this one rises up 2 and the run is 1 and 2/1 is 1. Rise/run is usually only necessary for small numbers.
32. given (0,3)
fond slope by formula y2-y1/x2-x1 with any two points in the table ( you are lucky to be able to use formula in this equation!!) 5.3-3/1-0
2.3/1= 2.3 is slope you are able to check if this is true by doing it with every (x,y) point they give you.. luckyly the slope holds true for all the equation is
y=2.3x+3
33. this one the way I did it was plugging in (x,y) onto each equation and see of any hold true
y=4x+2.1
y=4x^2+2.1
y=2.1×4^x
y=4x
Let's plug in (1,8.4)
8.4=4 (1)+2.1
8.4=4+2.1
8.4=6.1 not true
8.4=4 (1)^2+2.1
8.4=4+2.1
8.4=6.1 not true
8.4=2.1×4^1 (1)
8.4=2.1×4
8.4=8.4 TRUE
8.4=4 (1)
8.4=4 not true
