Triangle TAG is graphed as shown


Which of the following transformations will move triangleTAG so that point G is at the origin?

Answers

Answer:

The transformation is (x,y) to (x-2,y-6)

Step-by-step explanation:

First of all, we note the coordinates of the point G

The coordinates of the point G is (2,6)

To bring this to the origin, we are looking at bringing it to the point (0,0)

To do this, we subtract 2 from the x-value and 6 from the y value

So what we have is that;

(x-2) and (y-6)

Answer:

350

Step-by-step explanation:

Assumung that the $500 is before taxes, Jamel would have to pay $350.

$500 = price before discount

30% = discount

This means that Jamel would be paying 70% of the orginal price, because 30% of it is already taken off.

Answers

Answer:

The distance between the two points is [tex]\sqrt{26}[/tex]

Step-by-step explanation:

The formula of the distance between two points (x1, y1) and (x2, y2) is

d = [tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}[/tex]

∵ The points are (-1, 3) and (4, 2)

x1 = -1 and x2 = 4

y1 = 3 and y2 = 2

→ Substitute them in the formula of the distance above

∵ d = [tex]\sqrt{(4--1)^{2}+(2-3)^{2}}[/tex]

∴ d = [tex]\sqrt{(4+1)^{2}+(-1)^{2}}[/tex]

∴ d = [tex]\sqrt{(5)^{2}+1}[/tex]

∴ d = [tex]\sqrt{25+1}[/tex]

∴ d = [tex]\sqrt{26}[/tex]

The distance between the two points is [tex]\sqrt{26}[/tex]

Abigail drew a scale drawing of the oldest house in her town. The actual house is 64 feet long. Abigail's scale drawing is 8 inches long. What scale did Abigail use to draw the house? 8 inches equal 1 foot 8 inches equal 18 foot 1 inch equals 18 foot 1 inch equals 8 feet

Answers

Answer:

1 inch equals 8 feet

Step-by-step explanation:

Given that;

Abigail drew a scale drawing of the oldest house in her town.

The actual  length of the house = 64 feet long

Abigail scale drawing =  8 inches long

The scale he used in drawing the house is determined by choosing a perfect scale:

i.e

If 8 inches is used to draw an actual length of a house which is 64 feet long,

Then 1 inch should be able to draw (64 feet * 1 inch)/ 8 inches

So, 1 inch should be able to draw 8 feet long

The scale used to draw the given house is required.

The scale used to draw the diagram is 1 inch equals 8 feet.

Scale diagrams

Actual length of the house = 64 feet

Scale drawing length = 8 inches

So,

[tex]64\ \text{feet}=8\ \text{inches}[/tex]

Now, the inches to feet is required.

So, we divide both sides with 8.

[tex]\dfrac{64}{8}\ \text{feet}=\dfrac{8}{8}\ \text{inches}\\\Rightarrow 8\ \text{feet}=1\ \text{inch}[/tex]

So, 1 inch in the diagram is 8 feet of actual length.

Your cell phone provider charges a monthly fee of $30. You are also charged $0.07 per minute
for each minute. Last month, Mr. Gonzales' bill was $59.40. Let m represent the total number
of minutes Mr. Gonzales used last month. Use the verbal model below to write an equation.

Answers

Answer:

0.07m + 30 = 59.40

Mr Gonzalez used 420 minutes last month

Step-by-step explanation:

To represent how much money Mr. Gonzales was charged for using minutes, use the term 0.07m.

Then, add 30 to this to represent the monthly fee:

0.07m + 30

Lastly, set this equal to 59.40 because that was his total bill for the month:

0.07m + 30 = 59.40

So, the equation for the situation is 0.07m + 30 = 59.40

Solve for m in the equation:

0.07m + 30 = 59.40

0.07m = 29.40

m = 420

So, Mr Gonzalez used 420 minutes last month.

d = vt

where:

v = speed

d = distance

t = time

Based on the formula, each quantity is directionally proportional to each other. Since we don't have enough numbers to work with, we will utilize our concept skills.

If the car travels half the speed, then the car is slowing down and covers a short distance in a certain amount of time than it did originally. So we divide the default distance by 2.

180 / 2 = 90

The new distance so far is 90 miles.

But now it takes the car 3 times as long to get to its destination. The longer it takes, the more distance you will cover. Multiply the current distance by 3.

90 * 3 = 270

The car travels 270 miles.

Given f of x equals 6 1 minus x , what is the value of f of negative 6 ?

Answers

Answer:

answer will be 67

Step-by-step explanation:

f(x) = 61 - x

x = -6

hence we substitute the value of x in f(x)

f(-6) = 61 - (-6)

= 61 + 6

= 67

The value of the function f(x) = 6(1 - x) at x = -6 will be given 42.

What is a function?

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The function is given below.

f(x) = 6(1 - x)

The value of the function at x = -6 will be given as,

f(-6) = 6[1 - (-6)]

Simplify the equation, then we have

f(-6) = 6[1 - (-6)]

f(-6) = 6(1 + 6)

f(-6) = 6 × 7

f(-6) = 42

The value of the function f(x) = 6(1 - x) at x = -6 will be given 42.

A.) This system has no solutions.

Step-by-step explanation:

y = 1/2x + 4

-1/2x + y = -5

-1/2x + (1/2x + 4) = -5

4 = -5

The system has no solutions, if we graph it, we get that it has the same slope with two different y-intercepts, these two are parallel. These two points will never meet at a point.

Answer:

use the relationship between coefficients of a pair of linear equations for no solutions i.e. a1/a2 equal to b1/b2 not equal to c1/c2 .

Here, a is coefficient of x and b is coefficient of y and c is constant term in both equation but make sure that you put the values of a1,a2,b1,b2,c1 and c2 after converting both equation in the form ax+by+c=0 with proper sign and here y=1/2(x) +4 is equation 1 and other is equation 2
