Step-by-step explanation:

Lucas and Tony were trying to solve the equation:

x^2=16x+25x  

2

=16x+25x, squared, equals, 16, x, plus, 25

Lucas said, “The x^2x  

2

x, squared term is isolated, so I"ll take the square root of both sides and solve.”

Tony said, “I'll solve using the quadratic formula with a=1a=1a, equals, 1, b=16b=16b, equals, 16, and c=25c=25c, equals, 25.”

Whose solution strategy would work?

Neither Lucas's approach for the solution is correct nor Tony's approach.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Lucas approch,
x² = 16x + 25
√x² = √16x + 25
x = √16x + 25

No further solution by Lucas,

Now,
Toy's approach,
for equation,

x² = 16x + 25

Using quadratic formula he figured it out a = 1, b = 16 ad c = 25, which is wrong from the equation a = 1, b = -16, and c = -25.

Thus, Neither Lucas's approach for the solution is correct nor Tony's approach.

Answer:

charges for the first hour = $7.55

charges for each additional hour = $1.55

c = 1.55h + 7.55

Step-by-step explanation:

Let

x = charges for the first hour

y = charges for each additional hour

x + 2y = 10.65 (1)

x + 5y = 15.30 (2)

Subtract (1) from (2)

5y - 2y = 15.30 - 10.65

3y = 4.65

y = 4.65/3

= 1.55

y = $1.55

Substitute y = 1.55 into

x + 2y = 10.65

x + 2(1.55) = 10.65

x + 3.10 = 10.65

x = 10.65 - 3.10

= 7.55

x = $7.55

c = 1.55h + 7.55

2 9/10 minus 8/10

Subtract

2 1/10

PLZ MARK ME BRAINLIEST.

Answer:

2 1/10

Step-by-step explanation:

2 9/10 - 4/5. You need the minus because it says lost. That means you have to take away which is the same as minus.

The 4/5 have the same denominator as 2 9/10. This reason is because the denominator of 5 is lesser than the denomintor of 10. You don't have to do this step, but it will make it easier to solve.

2 9/10 - 8/10 = 21/10 OR 2.1 OR 2 1/10. Subtract them both to get the answer.

Answer:

A ∪ B = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}

A ∩ B = {5}

Step-by-step explanation:

A ∪ B means all the elements in sets A and B without repetition

A ∩ B means the common elements in the two sets A and B

∵ Set A = {5, 6, 7, 8, 9, 10}

∵ Set B = {2, 3, 4, 5, 11, 12, 13}

→ To Find A ∪ B, write all the elements in the two sets but don't

   repeat the common element

∵ 5 is a common element in the two sets

∴ Don't repeat it in A ∪ B

∴ A ∪ B = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}

→ To find A ∩ B, write the common elements in the two sets

∵ 5 is the only common element in the two sets

∴ A ∩ B = {5}

Answer:

Step-by-step explanation:

y=5x-2

slope of the line is 5 because if we compare to

y=mx+b where m is the slope we see m=5

Points (0,-2), (2,8), (4,18)

slope between the points (0,-2), (2,8)

m=(y2-y1)/(x2-x1) = -2-8/0-2 = -10/-2 = 5

slope between the points (4,18), (2,8)

m=(y2-y1)/(x2-x1) = 18-8/4-2 = 10/2=5

slope between the points (4,18), (0,-2)

m=(y2-y1)/(x2-x1) = 18+2/4-0= 20/4 =5

Answer:

True

Step-by-step explanation:

The perpendicular bisector of the opposite side to the vertex bisects the angle at the vertex into two equal parts and also bisects the triangle into two equal parts.

Let A be the angle at the vertex, then assume that the angle is an isosceles triangle with base angles B.

We need to show that A = 180 - 2B for an isoceles triangle

The perpendicular bisector bisects A into two so the new angle in the vertex one half of the bisected triangle is A/2.

Since this half triangle is a right-angled triangle, the third angle in it is 90.

So, A/2 + B +  90 = 180 (Sum of angles in a triangle)

subtracting 90 from both sides, we have

A/2 + B + 90 - 90 = 180 - 90

A/2 + B = 90

subtracting B from both sides, we have

A/2 + B = 90

A/2 = 90 - B

multiplying through by 2, we have

A = 2(90 - B)

A = 180 - 2B

Since A = 180 - 2B, then our triangle is an isosceles triangle.
