20-34+ 8/2 =? PLS HELP ME I GIVE ALL MY POINTS.

Answers

Answer:

-10

Step-by-step explanation:

20-34=-14, 8/2 is just 4, so add 4 to -14 which = -10

folllowing the order of operations (parentheses, exponents, multiplication, division, addition, subtraction or PEMDAS) we know that we need to solve for 8/2 first.
8/2=4
then we know our new equation looks like 20-34+4=x. now we need to add.
34+4=38
now we have the new equation 20-38.
20-38=-18
your answer is -18.

After being dilated by a scale factor 1.5?

Answers

Given:

The given figure is dilated by a scale factor 1.5.

To find:

The coordinates of B' and C'.

Solution:

If a figure is dilated by a scale factor k at point (a,b), so the rule of transformation is

[tex](x,y)\to (k(x-a)+a,k(x-b)+b)[/tex]

From the given figure it is clear that A(3,-3), B(-2,2) and C(-3,-5).

The figure is dilated by a scale factor 1.5 at point A(3,-3), so the rule of transformation is

[tex](x,y)\to (1.5(x-3)+3,1.5(x-(-3))+(-3))[/tex]

[tex](x,y)\to (1.5(x-3)+3,1.5(x+3)+(-3))[/tex]

[tex](x,y)\to (1.5(x)-4.5+3,1.5(x)+4.5-3)[/tex]

[tex](x,y)\to (1.5x-1.5,1.5x+1.5)[/tex]

Using this rule, we get

[tex]B(-2,2)\to B'(1.5(-2)-1.5,1.5(2)+1.5)[/tex]

[tex]B(-2,2)\to B'(-3-1.5,3+1.5)[/tex]

[tex]B(-2,2)\to B'(-4.5,4.5)[/tex]

And

[tex]C(-3,-5)\to C'(1.5(-3)-1.5,1.5(-5)+1.5)[/tex]

[tex]C(-2,2)\to C'(-4.5-1.5,-7.5+1.5)[/tex]

[tex]C(-2,2)\to C'(-6,-6)[/tex]

Therefore, the coordinates of B' and C' are B(-4.5,4.5) and C'(-6,-6).

Answers

Answer:

$1.10

Step-by-step explanation:

What we know:

Emilio has 2 quarters, 4 dimes, 3 nickels, and 5 pennies.

Quarters = 0.25 * 2

Dimes = 0.1 * 4

Nickels = 0.05 * 3

Pennies = 0.01 * 5

$0.50 + $0.40 + $0.15 + $0.05

$0.90 + $0.20 = $1.10 in total

Write the slope of a line perpendicular to y=-6x+4. Explain why it is perpendicular

Answers

Answer:

1/6 is the slope since you have to flip it

Step-by-step explanation:

Answer:

The slope of a line perpendicular to the equation is 1/6 or x/6.

This is perpendicular because it is the reciprical of the other equation

Step-by-step explanation:

y=-6x+4.

the slope intercept form is y=mx+b

m is the slope

m=-6

for the equation to be perpendicular then the slope is the reciprical

Knowing this lets find a line perpendicular to this equation

Equation:

y=1/6x+2/3

or

y=x/6+2/3

Answers

Answer:

m = 2

Step-by-step explanation:

The given equation is :

8x – 4y - 9 = 0

The general equation of a line is given by :

y = mx+b ...(1)

here m is slope and b is y-intercept

Equation (1) can be written as :

8x – 4y = 9

Dividing both sides by (-4)

[tex]\dfrac{8x}{-4}-\dfrac{4y}{-4}=\dfrac{9}{-4}\\\\-2x+y=-\dfrac{9}{4}\\\\y=2x+\dfrac{-9}{4}[/tex] ...(2)

Comparing equation (1) and (2), we get :

m = 2

Hence, the slope of the line is 2.

2. Subtract 6a from both sides to get:
