Alexis wrote 28 - 8 = 20. Then she
wrote 28 -8 + 9 = 20 – 9. Are her
equations balanced? Explain.

Answers

Answer:

no this is because 28-8+9=29 and 20-9=11

Step-by-step explanation:

Answer:

Her equation is not balanced.

Because 28 - 8 + 9 = 20 - 9

                 29 = 11 ( its not balanced)

She put the  same symbol or sign on both side.Here she put different sign on both side .so this equation is not balanced.

A right triangle with the side AB as a length of 35 cm and another side length BC with 12 cm. What is the hypotenuse length of the right triangle?

Answers

The formula to find the hypotenuse is a^2 + b^2 = c^2. Let’s call side AB, “a” and call side BC, “b”. Now “a” = 35 cm and “b” = 12 cm. Using the formula, you square (multiply the number by itself) “a” and “b” then add them together. This would look like 35^2 + 12^2 =c^2. When you do the multiplication it ends up as 1,225 + 144 = c^2. Add 1,225 and 144 together to get 1,369 = c^2. Last step is to square root both sides to get 37 = c. So the hypotenuse of this triangle would be 37.
Hope this helps!

y= -3x + 1 and y= x - 3

Answers

Answer:

x= 1

y= -2

Step-by-step explanation:

equation (1): y= -3x+1

equation (2): y=x-3

solve the system of equations by substitution:

step1: sub ( x-3 ) for y in equation 1:

y = -3x+1

x-3 = -3x+1

step2: simplify the equation to get x:

(add 3 for both sides)

x = -3x+4

(add 3x for both sides)

4x = 4

(divide 4 from both sides)

x = 1

step3: sub the value of x (x=1) in equation 2:

y = x-3

y = 1-3

step4: solve the equation to get y:

y = -2

Write down the value of angle y, giving a reason for your answer
Y=
Other angle given is 67 degrees

Answers

Answer:

y would be 67 as well.

Step-by-step explanation:

they are alternate interior angles. hope it helps

In part (a) the missing angle of a triangle is 70 degrees and in part (b) the missing angle is 67 degrees.

What is the triangle?

In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

Part(a)

We have a triangle shown in the picture.

The two lengths of a triangle are equal.

The angle opposite to the sides will be equal.

As we know,

The triangle's interior angles add up to 180°.

180 = 55 + 55 + x

x = 180 - 110

x = 70 degrees

In part (b)

There are two parallel lines shown in the picture.

The angle y will be the same as 67 degrees because two parallel lines are cut by a transversal line.

Thus, in the part (a) the missing angle of a triangle is 70 degrees and in part (b) the missing angle is 67 degrees.

Step-by-step explanation:

Find the average by adding the 2 fractions and dividing the sum by 2

[tex]\frac{1}{2}[/tex] + 1 [tex]\frac{1}{4}[/tex]

= [tex]\frac{1}{2}[/tex] + [tex]\frac{5}{4}[/tex]

= [tex]\frac{2}{4}[/tex] + [tex]\frac{5}{4}[/tex]

= [tex]\frac{7}{4}[/tex]

What is the length of line segment HJ?

Answers

The answer is 5 radical 3

Answer:

b = 5√3 (units)

Step-by-step explanation:

To solve this problem, use the pythagorean theorem, where a^2+b^2 = c^2, a and b are the legs of the triangle and c is the hypotenuse.

In this case, we are finding the missing leg, and we were given one of the legs and the hypotenuse.

a^2+b^2 = c^2 (pythagorean therorm)

5^2+b^2 = 10^2 (substitute one leg and the hypotenuse)

25+b^2 = 100 (square the numbers)

b^2 = 75 (subtract 25 from both sides)

b = √75

b = √25 * √3 (factor out√75)

b = 5 * √3 (find square root of√25)

b = 5√3

reflection and translation.

Given:

The different transformation in the options.

To find:

The transformation that would result in the perimeter of a triangle being different from the perimeter of its image.

Solution:

In option 1,

[tex](x,y)\to (y,x)[/tex]

It represents reflection across the line y=x.

In option 2,

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

It represents reflection across the x-axis.

In option 3,

[tex](x,y)\to (4x,4y)[/tex]

It represents dilation by scale factor 4 and the center of dilation is at origin.

In option 4,

[tex](x,y)\to (x+2,y-5)[/tex]

It represents translation 2 units right and 5 units down.

We know that the reflection and translation are rigid transformations, It means the size and shape of the figure remains the same after transformation.

So, the perimeter of the figure and its image are same in the case of reflection and translation.

But dilation is not a rigid transformation. In dilation, the figure is similar to its image. So, the perimeter of the figure and its image are different in the case of dilation.

Therefore, the correct option is 3.
