Answer:

Line m is not parallel to Line n.

Line m is perpendicular to Line k

Step-by-step explanation:

1. Calculate slopes of n and m. N = -2 and M = -7/4. The two slopes aren't the same thus they are not parallel

2. Slope of m = -7/4 and k = 4/7. By definition of perpendicular these two fit the description. (to be perpendicular, k = -1/m

Step-by-step explanation:

100% = $12

1% = 100%/100 = 12/100 = $0.12

15% = 1% × 15 = 0.12 × 15 = $1.80

the 15% tip is $1.80

I don't know if someone already answered this and you're thanking them or if you need help, but the answer is 25.

Step-by-step explanation:

3/5 turns to 60% and 0.35 turns to 35% so it is 60-35 which equals 25

Answer:

3/5 to a percent is 60%

0.35 to a percent is 35%

So,

60%-35%=0.25

y=(4/3)x-5

y = -5x+1

Step-by-step explanation:

The basic form of an equation of a straight line in slope intercept form is y=mx+b, where m is the slope and b the y intercept (the value of y when x=0):

1) slope=4/3, y-intercept=-5 .

y = mx + b:  y=(4/3)x-5

2) slope =-5, y-intercept =1.

y = mx + b:  y = -5x+1

$6.80-$4.80=$2.00

0.30x16=$4.80

$0.30x4=$2.00

$4.80+$2.00=$6.80

Answer: 25% of 60 is 15, 10% of 40 is 4, 12% of 450 is 54, and 20% of 225 is 45.

So a is 15, b is 4, d is 450, and c is 225.

1. To find the sum of two integers with like signs simply add them and keep the sign same as integers

for example:

[tex]2 + 3 = 5 \\ - 2 + ( - 3) = - 5[/tex]

2. To find the sum of the integers with unlike signs just subtract them and then keep the sign of the bigger integer.

For example:

[tex] - 3 + 5 = 2 \\ - 5 + 3 = - 2[/tex]

Step-by-step explanation:

there is no big "trick" involved.

you just need to do the multiplication and then move the terms into the right spot, so that the x-, y- and constant terms are in the same place as the generic Ax + By = C

y + 5 = 4(x + 1)

y + 5 = 4x + 4

-4x + y = -1

or (after multiplying both sides by -1)

4x - y = 1

yes, B = 1 (or -1), so you could write 1y (or -1y) instead of only y (or -y).

Answer:

18x^2 + 66x

Step-by-step explanation:

Apply the distributive property of multiplication:

6x (3x +11) becomes 18x^2 + 66x

The equivalent expressions for given expressions is 18x²+66x.

The given expression is 6x(3x +11).

Equivalent expressions are equivalent expressions  that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

The equivalent expressions for given expressions can be determined as follows

Using distributive property 6x(3x +11)

= 18x²+66x

Therefore, the equivalent expressions for given expressions is 18x²+66x.

Answer:

Midsegment of a triangle is half the length of the third side in order to fill in the triangle.

So, the perimeter of a midsegment tirangle is half the perimeter of QRS.

Perimeter of QRS:

For finding out it's perimeter sum up all the sides while adding alike variables together.

=> (2x + 5) + (3x - 1) + (5x)

= 2x + 3x + 5x + 5 - 1

= 10x + 4

Perimeter of mid-segment triangle:

Perimeter of QRS divided by 2

Step-by-step explanation:

y-Intercept = (0 , -5)

Slope / m = -4

y - y1 = m(x - x1)

y + 5 = -4(x - 0)

y = -4x - 5 → Equation

v = 3 (r - 1)

v = 3(- 1 - 3) ---- substititing

v = -3 - 9 ----- solved the parenthesis

v = -12 ----- -3 -9 = -12
