Does mapping the triangle DEF onto triangle GHI prove the two triangles are congruent? Explain your reasoning.

Answer:

CD = 7

Step-by-step explanation:

Given that the triangles are congruent, then corresponding sides are congruent, that is

CD = AB , substitute values

3y + 1 = 15 - 4y ( add 4y to both sides )

7y + 1 = 15 ( subtract 1 from both sides )

7y = 14 ( divide both sides by 7 )

y = 2

Thus

CD = 3y + 1 = 3(2) + 1 = 6 + 1 = 7

D. Reflection across x-axis

Step-by-step explanation:

When plotting the two points & then connecting the dots, it will not touch y-axis at all - it will be straight line and cross x axis

Answer:

The coordinates of the orthocenter of the triangle is;

(-2/3,1/3)

Step-by-step explanation:

To find the coordinates of the orthocenter, all we have to do is solve for x and y of the given altitudes

We can get this by solving both equations simultaneously

Simply equate the two y’s

x + 1 = -2x-1

x + 2x = -1-1

3x = -2

x = -2/3

To get y, simply substitute into any of the equation, the value of x

y = -2/3 + 1

y = 1/3

Answer:

equation: 10 + 0.05x=22

Step-by-step explanation:

the next step after writing the equation would be to subtract 10 from both sides to get 0.05x=12. after this you would then have to divide 12 by 0.05 to get 240 minutes. you could check it by putting 240 in for x to get 10+0.05(240)=22. you would then multiply 0.05 by 240 to get 12 and then add 10 onto it to get 22 which was already given.

Answer:

  equation: 10 +0.05m = 22

  solution: Bob used 240 minutes in July

Step-by-step explanation:

Bob's bill is the total of the fixed fee and the charges based on minutes. The latter is 0.05m, where m is the number of minutes. Hence, Bob's July bill is ...

 10 + 0.05m = 22 . . . . . total of charges for July is $22

__

The equation is solved by subtracting the constant and dividing by the coefficient of m.

  0.05m = 12 . . . . . subtract 10

  m = 12/0.05 = 240

Bob used 240 minutes in July.

Step-by-step explanation:

Given that x is multiplied by 7 = 21 Then

7 * x = 21

or x = 21/ 7

Therefore x = 3.

Answer:

Solution,

here,

x+7=21

x=21-7

Therefore,x=14

Answer:

y=-4/3x-3

Step-by-step explanation:

The equation of the line that passes through the given point will be equal to (-4/3)x - 3.

Equations are mathematical expressions that have two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be equal, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the given information in the question,

The given equation is,

4x + 3y = 15

And the point is (-3, 1)

3y = 15 - 4x

y = (-4/3)x + 15

The line has a slope, of -4/3.

Then, use the equation,

B = y - mx

B = 1 - (-4/3 × 3)

B = -3

So,

y = (-4/3)x - 3

Step-by-step explanation:

Each side of the square fence = 6 meters

Perimeter of the square fence = 4 × length

= 4 × 6

= 24 meters

They already have 10 meters of fencing

How many more meters of fencing should they buy?

= Total meters - available meters

= 24 meters - 10 meters

Answer: The point (5,7) is on the line 5x+6y = 67

=====================================================

Explanation:

(5,7) means x = 5 and y = 7 pair up

Plug in those values to get...

5x + 6y = 67

5*5 + 6*7 = 67

25 + 42 = 67

67 = 67

We get the same number on both sides after fully simplifying. This means the equation is true. A true equation in the last step means the first equation is true when (x,y) = (5,7).

Therefore, the point (5,7) is a solution and it is on the line 5x+6y = 67.

Answer:

12,145

Step-by-step explanation:

If 347 cans is the max PER week, and they have 35 weeks, then all we need to do is multiply 347 times 35.

347*35 = 12,145

The max amount of cans they can collect in 35 weeks is 12,145 cans.

Answer: 12,145

Step-by-step explanation:

Answer:

We know Mr. Jackson will have to pay 0.55 dollars per mile and that he's traveling 61 miles, so, if we want to know. how much will he pay, we can multiply the quantity of miles (61) per the cost of these:

0.55 * 61 = 33.55

So we know he will have to pay 33.55 dollars, and, as the travel is round, considering he will travell the same quantity of miles, he will pay twice

33.55 * 2 = $67.10

He has more budget than the needed for the travel

Answer:

Mr. Jackson will be under his budget.

Step-by-step explanation:

We know that Mr. Jackson has a budget of only $70 for the trip. We know that the trip will be reimbursed $0.55 per mile. Mr. Jackson is traveling 61 miles. Therefore, we need to multiply $0.55 by 61.

61 x 0.55 = $35.55

Since $35.55 is less than $70, he will be under his budget.

Answer:

Natalie cannot make it over the fence.

Step-by-step explanation:

After reading the statement, we must demostrate if the following inequation is possible, that is:

[tex]-16\cdot t^{2}+18\cdot t+5 \ge 12[/tex]

After some algebraic handling we find this equivalent expression:

[tex]16\cdot t^{2}-18\cdot t +7\le 0[/tex] (1)

The polynomial is factorized by the Quadratic Formula:

[tex]\left(t-0.563-i\,0.348)\cdot (t-0.563+i\,0.348)\le 0[/tex]

Since all roots are complex, we conclude that Natalie cannot make it over the fence.

Answer:

y=2x+2

Step-by-step explanation:

Answer: y = 2x

Step-by-step explanation:

y=mx+b

m is the slope. so if the slope is 2 we can fill in 2 for m.

y = 2x + b

now we are going to plug in the point they gave us (1, 2) to find b.

1 is the x coordinate of the point and 2 is the y coordinate. so we put 1 in for x and 2 in for y.

2 = 2(1) + b

2 = 2 + b

b = 0

so our equation is y = 2x + 0, or y = 2x
