Answer:

  DOG = 270

Step-by-step explanation:

270 × 3 = 810

_____

The only numbers that end in the same digit when multiplied by 3 are 0 and 5.

  0×3 = 0

  5×3 = 15

If G is 5, then you are looking for digits DO than give a product of 80 when multiplied by 3. 80 is not divisible by 3, so that doesn't work.

G must be 0.

Then the product of DO and 3 is 81, so DO = 81/3 = 27.

The solution is ...

  D = 2

  O = 7

  G = 0

Answer:

The rate of change of f(x) is greater than that of g(x)

They have the same y intercept of 14

Step-by-step explanation:

Given

g(x) = -\frac{1}{2}x + 14

Table for function f(x)

Required

Compare their rate of change and intercept

For g(x), we have:

g(x) = -\frac{1}{2}x + 14

The form of an equation is:

y = mx + b

Where

m = slope

b =y\ intercept

So:

m = -\frac{1}{4}

b = 14

For f(x): Start by calculating the slope (m)

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{17-16}{6-4}

m = \frac{1}{2}

The intercept is calculated using:

m = \frac{y_2 - y_1}{x_2 - x_1}

Where

(x_1,y_1) = (-2,13)

(x_2,y_2) = (0,y) --- we want to solve for y

So:

\frac{1}{2} = \frac{y - 13}{0 --2}

\frac{1}{2} = \frac{y - 13}{2}

Multiply both sides by 2

1 =y - 13

Make y the subject

y =1 + 13

y = 14

So, we have:

m = -\frac{1}{4} and b = 14 -- for g(x)

m = \frac{1}{2} and y = 14 --- for f(x)

By comparison:

The rate of change (i.e. slope) of f(x) is greater than that of g(x) because 1/2 > -1/2

They have the same y intercept of 14

What is the solution to the system of equations? 2x+4t=12
katen-ka-za [31]

Answer:

C. (8, -1)

Step-by-step explanation:

{y = ¼x - 3}

{2x + 4y = 12

2x + 4[¼x - 3] = 12

2x + x - 12 = 12

3x - 12 = 12

+ 12 + 12

_________

3x = 24

__ __

3 3

x = 8 [Plug this back into both equations above to get the y-coordinate of −1]; -1 = y

Square ABCD is shown with four congruent images such that ABCD FGHI JKLM NOPQ RSTU.
Anettt [7]

Answer:

  • <em><u>RSTU</u></em>

Explanation:

The question states the <em>congruent</em> images:

  • ABCD ≅ FGHI ≅ JKLM ≅ NOPQ ≅ RSTU

The order of the letters matters.

For instance, ABCD ≅ FGHI means that the vertex A is transformed into vertex F, the vertex B is transformed into the vertex G, the vertex C is transformed into vertex H, and the vertex D is transformed into vertex I.

From the images, the square ABCD is just shifted 9 units down to form the square FGHI. No refelection is needed.

As per the square RSTU only a reflection of square ABCE accross the y-axis makes the vertex A into vertex R, the vertex B into the vertex S, the vertex C into the vertex T, and the vertex D into the vertex U.
