Answer:

42.5 square units

Step-by-step explanation:

To solve, we can split this shape up into 4 known shapes:

2 unit by 2 unit triangle

2 unit by 2 unit square

2 unit by 5 unit triangle

3.5 unit by 9.0 unit rectangle

Now let's solve these areas:

2 x 2 = 4 / 2 = 2

2 x 2 = 4

2 x 5 = 10 / 2 = 5

3.5 x 9.0 = 31.5

Then add all these values together:

2 + 4 + 5 + 31.5 = 42.5

Step-by-step explanation:

it is a quadratic function

it is because it satisfies the equation f(x)= -3-5x+4x^2

Answer:

y = 2x + 5

Step-by-step explanation:

First, you must choose two ordered pairs from the table to solve for the slope (m):

Let (x1, y1) = (0, 5)

(x2, y2) = (1, 7)

Substitute the given values into the following slope formula:

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{7 - 5}{1 - 0} = \frac{2}{1} = 2[/tex]

Therefore, the slope (m) = 2.

The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b ).  It is also the value of y when x = 0. Looking at the given table, (0, 5) reflects the description of the y-intercept. The y-intercept (b) is the y-coordinate of (0, 5).

Given the slope (m) = 2, and y-intercept (b) = 5, the linear equation is:

y = 2x + 5

Answer:

18.75.

Step-by-step explanation:

If he already owes his mother 12.25 and borrows 6.50, we can add those numbers up to get the total amount of how much he owes his mother.

12.25 + 6.50 = 18.75

Therefore, Joseph's debt to his mother can be represented using the equation above.

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

Work Shown:

x = number of light bulbs

3.40x = total cost to buy x light bulbs, cost is in pounds

3.40x = 30

x = 30/(3.40)

x = 8.823529 approximately

Rounding down, we get 8

Note that,

Therefore, the highest number of bulbs that can be bought is 8.

The change given will be 30-27.20 = 2.80 pounds

First, find the scale factor:

8/4.6 ≈ 1.73913043478

12/1.73913043478 = 6.9

If triangle XYZ is similar to ABC then the length of the missing side is 6.90. It is obtained by using the scale factor concept.

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

It is given that ΔXYZ ≅ ΔABC.

Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.

When two triangles are similar their scale factor is the same for each side,

The scale factor is  obtained by taking the ratio of their sides,

=  AC / XZ

= 8 / 4.6

= 1.739

The length of side XY is found as,

Scale factor = AB / XY

1.739 = 12 / XY

XY = 6.90

Thus, if triangle XYZ is similar to ABC then the length of the missing side is 6.90. It is obtained by using the scale factor concept.

Answer:

y=-1/2x-9/2

Step-by-step explanation:

check picture

The equation of the line perpendicular to y = 2x - 3 that passes through the point (-3, -3) is y = (-1/2)x - 9/2 in slope-intercept form.

To find the equation of a line perpendicular to y = 2x - 3, we need to determine the slope of the original line and then find the negative reciprocal of that slope.

The original line has a slope of 2. The negative reciprocal of 2 is -1/2.

Now, we have the slope (-1/2) and the point (-3, -3) that the perpendicular line passes through.

We can use the point-slope form of a linear equation to write the equation of the line:

y - y1 = m(x - x1)

Substituting the values:

y - (-3) = (-1/2)(x - (-3))

y + 3 = (-1/2)(x + 3)

Expanding and simplifying:

y + 3 = (-1/2)x - 3/2

y = (-1/2)x - 3/2 - 3

y = (-1/2)x - 3/2 - 6/2

y = (-1/2)x - 9/2

Therefore, the equation of the line perpendicular to y = 2x - 3 that passes through the point (-3, -3) is y = (-1/2)x - 9/2 in slope-intercept form.

Answer: 4/10 = 2/5

2/8 = 1/4

3/5 = 3/5

4/12 = 1/3

6/10 = 3/5

3/6 = 1/2

Step-by-step explanation:

4/10 = 2/5

4/10 is not in its simplest form.

Both 4 and 10 can be divided by 2.

Therefore, 4/10 = 2/5

2/8 = 1/4

2/8 is not in its simplest form

2 / 2 = 1

8 / 2 = 4

Both 2 and 8 can be divided by 2, therefore, 2/8 = 1/4

3/5 = 3/5

3/5 is in its simplest form

3 and 5 are prime, so they don’t have any factors other than 1 and itself so they wouldn’t be able to be simplified.

4/12 = 1/3

4/12 is not in its simplest form

4 / 4 = 1

12 / 4 = 3

4 and 12 can be divided by 4, resulting in 1 and 3. Therefore, 4/12 = 1/3.

6/10 = 3/5

6/10 is not in its simplest form

6 / 2 = 3

10 / 2 = 5

6 and 10 can both be divided by 2, resulting in 3/5. Therefore, 6/10 = 3/5

3/6 = 1/2

3/6 is not in its simplest form

3 / 3 = 1

6 / 3 = 2

Both 3 and 6 can be divided by 3, resulting in 1/2

Therefore, 3/6 = 1/2

Short Answers:

4/10 = 2/5

2/8 = 1/4

3/5 = 3/5

4/12 = 1/3

6/10 = 3/5

Answer:

5m

Step-by-step explanation:

1.25m multiply by 4 sides equals 5m

The length of which ant walk will be the same as the perimeter of the square thus it will be 5 meters.

Perimeter is the addition of an external measure of sides it will always positive.

Perimeter of square = side + side + side + side

Given a table in form of a square,

Side of square = 1.25 m

The external measure of side = length of ant walk

1.25 + 1.25 + 1.25 +1.25 = Length of ant walkt

Length of ant walk = 5 meters.

Hence "The length of which ant walk will be the same as the perimeter of the square thus it will be 5 meters".
