The two ways of forming isosceles triangle by bending the metal strip using length by length by base are

A triangle that have the two sides equal is referred to as an isosceles triangle.

Using a strip of 20 inches long to construct an isosceles triangle means that the perimeter of the triangle is 20 inches

the perimeter is equal to base + length + length

bending 6 inches already means one of the dimensions is gotten then fo the other is based on if

if the 6 is base then minus the 6 from 20 and divide the rest for the length

20 - 6 = 14

the two lengths is 14 one length is 7. so we have 6 + 7 + 7 = 20

If the 6 is length then get another 6 and the rest is base

20 - 6 = 14

14 - 6 = 8

therefore we have 6 + 6 +8 = 20 inches

The equation of the line in slope - intercept form is [tex]y=\frac{-7}{4}x-5[/tex]


Explain what the slope-intercept form is?

Simply put, the slope-intercept form is the way to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible. This expression is sometimes referred to as y = mx + b form

Given: x = -4 , y = 2 and b = -5

y = mx + b

2 = m (-4) + (-5)

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

Answer:

12.5 72

Step-by-step explanation:

Because shows that the basketball player wear size 11.5 73 inches tall so basically the answer would be 12.5 72

The equation of the regression line is y = 0.77x + 61.95. The residual is 2.2 inches. The residual means that the gap between the estimated and anticipated values is 2.2 inches.

A regression line shows a linear connection between the y-dependent axis's variables and the x-independent axis's variables. The connection is determined by examining the data pattern created by the variables.

From the table, the points are given as follows:

(7, 64.5), (10, 70), (12.5, 72), (8.5, 71), (9, 69), (10, 70), (11, 75), (12.5, 69), (13, 71), (10.5, 68).

Inserting these points into the linear regression calculator, the equation is given as follows:

y = 0.77x + 61.95 ...(i)

For a shoe size of 11.5 inches, the predicted height is given as below:

y = 0.77(11.5) + 61.95 = 70.8 inches.

The residual is the gap between the estimated and anticipated values, hence:

Residual = 73 inches - 70.8 inches = 2.2 inches.

Here in the rhombus ABCD the value of y is 7.5.

A rhombus is a unique kind of quadrilateral with four equal sides and perpendicular diagonals that cut the angles and one another in half.

So here 4x+15 = 7x+2 and

12y = 90.

To find the remaining values by first solving for each variable, then substituting as necessary.

4x+15=7x+2

15=3x+2

13=3x

13/3 = x

BC is 4x+15

= 4(13/3)+15

= 52/3 + 45/3

= 97/3

CD is 7x+2

= 7(13/3)+2

= 91/3 + 6/3 = 97/3

Then, find 12y=90 and y=7.5.

AFB is a 90° angle (12(7.5)).

BCF is a 4y-1 = 4(7.5)-1 = 29 angle.

Because the diagonal cuts the angle in half, angle BCD is equal to 58. Angle ABC thus becomes 180-58 = 122.

Therefore the value  of  y  is 7.5 .

Step-by-step explanation:

75-29.50 = 45.50

45.50/0.55 = 82.7272727273

82 x 0.55 = 45.10

45.10+29.50 = 74.60

The solution to the questions are:

From the question, we have the following parameters that can be used in our computation:

Length = 350 - 2x

Width = x

The area of a rectangle is the product of its dimensions

So, we have

Area = Length x Width

Substitute the known values in the above equation, so, we have the following representation

A = (350 - 2x) * x

Evaluate

A = 350x - 2x²

Differentiate and set to 0

350 - 4x = 0

So, we have

4x = 350

Divide by 4

x = 87.5

Recall that

Length = 350 - 2x

So, we have

Length = 350 - 2 x 87.5

Evaluate

Length = 175

The area is then calculated as

Area = Length x Width

So, we have

Area = 175 x 87.5

Evaluate

Area = 15312.5 square meters

Hence, the area is 15312.5 square meters

Slope is the ratio of the change in the y-coordinates to the change in the x-coordintes of any two given points.

It is a measure of the steepness of a line.

Slope may be positive or negative

slope of the line joining the the points (-3,4) and (1,1)

slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

[tex]x_{1}[/tex] = -3, [tex]x_{2}[/tex] = 1, [tex]y_{1}[/tex] = 4, [tex]y_{2}[/tex] = 1

slope = 1-4 / 1 - -3

slope = -3/4

since the two lines are parallel their slopes are equal.
