8. Line AB passes through A(-2,4) and B(-8,-6).
netineya [11]

Answer:

AB : \frac{5}{3}

PT : -\frac{1}{5}

Step-by-step explanation:

The line AB passes through A(-2,4) and B(-8,-6) points.

Therefore, the slope of the line AB will be \frac{4-(-6)}{-2-(-8)} =\frac{5}{3} (Answer)

Again line PT passes through P(3,-1) and T(8,-2) points.

Therefore, the slope of the line PT will be \frac{-1-(-2)}{3-8} =-\frac{1}{5}. (Answer)

Here we have applied the formula of slope of a straight line passing through the points (x_{1},y_{1}) and (x_{2},y_{2}  ) as given by \frac{y_{1}-y_{2}  }{x_{1}-x_{2}  }.

PLS HELP !!! I need this question done quick
NeX [460]

Answer:

a. 17  b. 51

Step-by-step explanation:

Follow Order of Operations (PEMDAS):

Parentheses, Exponents, Multiplication/Division, Addition/Subtraction

a.  9 + 4² - (4-2) • 4

9 + 4² - (4-2) • 4 –––Start with (4-2) = 2 (parentheses)

9 + 4² - 2 • 4 ––– 4² (exponents)

9 + 16 - 2 • 4 ––– 2 • 4 (multiplication)

9 + 16 - 8 ––– 9 + 16 (addition)

25 - 8 ––– 25 - 8 (subtraction)

17

b. 15 - 4 + 2(7-3) • 5

15 - 4 + 2(7-3) • 5 ––– Start with 2(7-3)

~ Note: this can be done using distributive property (2•7 - 2•3) OR solving the parentheses first and then multiplying 2(4). Both get 8 and same end result.

15 - 4 + 8 • 5 ––– 8 • 5 (multiplication)

15 - 4 + 40 ––– 15 - 4 (subtraction) *Note: Subtraction and addition are interchangeable in the order because you do it left to right*

11 + 40 ––– 11 + 40 (addition)

one cubic foot of chemical weighs 60 pounds. How many pounds of the chemical can a container withe these dimensions hold? Pictur
Goshia [24]

Answer:

3600 pounds

Step-by-step explanation:

One cubic foot of a chemical weighs 60 pounds.

1 ft³ of chemical = 60 pounds

We need to find how many pounds in the container whose dimension 6 ft, 4 ft and 2.5 ft

l = 6 ft

b = 4 ft

h = 2.5 ft

Volume of box = lbh

                        = 6 x 4 x 2.5

                        = 60 ft³

As we are given

1 ft³ of chemical = 60 pounds

60 ft³ of chemical = 60 x 60 = 3600 pounds
