4|m-n|
If m=-7 and n=2

Answers

you would first substitute -7 for m and 2 for n. It would look like this: 4| -7-2 | . we first solve the absolute value because it is the first step in PEMDAS or order of operations. -7-2 is equal to -9. Our equation should look like this now: 4 |-9| . we solve the absolute value portion, the absolute value of a negative number is the the same number but positive. the absolute value would be 9. (we just take the negative symbol off). we now have 4 x 9. This is equal to 36.

36 is the answer.

Two pencils and a ruler cost 98 cents in total. One pencil and 2 rulers cost $1.24 in total. Find the cost of each item.

Answers

Answer:

2.16

Step-by-step explanation:

r = cost of ruler

p = cost of pencil

 

r = 2p

6r + 15p = 2.16

 

Substitute 2p in place of r in 2nd equation and solve for p

 

6(2p) + 15p = 2.16

12p + 15p = 2.16

27p = 2.16

Answer: 2.16
6(2p)+15p=2.16
12p+15p=2.16
27p=2.16

Given a quadratic equation px^2 + 8x + 2 does not have real roots. Determine the range of the values of p.
[4 marks]

Answers

Step-by-step explanation:

For a quadratic equation to have no real roots, the discriminant b² - 4ac must be negative.

For px² + 8x + 2 = 0,

We have a = p, b = 8 and c = 2.

=> (8)² - 4(p)(2) < 0

=> 64 - 8p < 0

=> 8p > 64

=> p > 8

Hence the range for p is p > 8.

AFE=35 degrees because 180=55+90+x

Answer:

∠ AFE = 35°

Step-by-step explanation:

∠ EFD = ∠ BFC = 55° ( vertically opposite angles )

Since BD is a straight line , then

∠ EFD + ∠ AFE + AFB = 180°, that is

55° + ∠ AFE + 90° = 180

∠ AFE + 145° = 180° ( subtract 145° from both sides )

∠ AFE = 35°

The price of nails, n, is $1.29/lb. The price of washers, w, is $0.79/lb. The price of bolts, b, is $2.39/lb.

Section a .Write an expression to represent the total price of the supplies

Section b. What is the total cost of buying 2 pounds of nails, 4 pounds of washers and 3 pounds of bolts?

Answers

Answer: 1.29n + 0.79w + 3.39b  is the expression.

The total cost is $12.91

Step-by-step explanation:  Substitute the number of pounds for each given supply. Multiply to get the individual amounts, then add all of those amounts to find the total cost.

1.29(2) + 0.79(4) + 2.39(3) = total

2.58 + 3.16 + 7.17 = 12.91

Answer:

1.29n + 0.79w + 2.39b

1.29(2) + 0.79(4) + 2.39(3) =

2.58 + 3.16 + 7.17 = $12.91

SOLVE USING SUBSITUTION

Show work

Answers

Answer:

( 1, 5 )

x = 1

y = 1

Step-by-step explanation:

y = x + 4

2x + 3y = 17

Since they gave us the value of "y" we can use that and substitute it into the equation to find what "x" is.

2x + 3y = 17

2x + 3 ( x + 4 ) = 17

Distributive Property

2x + 3 * x + 3 * 4 = 17

2x + 3x + 12 = 17

Combine Like Terms ( 2x and 3x)

5x + 12 = 17

Subtract 12 on both sides of the equation

5x + 12 - 12 = 17 - 12

5x = 5

Divide by 5 on both sides to isolate the variable

5x/5 = 5/5

x = 1

Now that we have what "x" is, we can substitute that into one of the equations to get the value of "y"

y = x + 4

y = 1 + 4

y = 5

x = 1

y = 5

( x, y )

( 1, 5 )
