Answer:

y=-5/2x-1

Step-by-step explanation:

change the equation to slope intercept form

y=-5/2x+6

graph the point (-2, 4)

use the slope of the equation to find the y intercept

y intercept = -1

write equation of the parallel line using the same slope of the first line

123 is a linear pair with the inside angle so
180-124= 57. Now we have two inside angles and a triangle has to be 180 degrees so
57+42=99 we know that both angles equals 99 so
180-99=80. The third angle is 81 and is a linear pair with x soooo
180-81=99
X is equal to 99. You can also do corresponding angles and have X be 99 because of the inside angle that’s also 99

solve this equation 5x+17= 42

Answers

Answer:

x = 5

Step-by-step explanation:

5x + 17 = 42

5x = 25

x = 5

Answer:

x = 5

Step-by-step explanation:

5x+17= 42

Subtract 17 from each side

5x+17-17= 42-17

5x = 25

Divide each side by 5

5x/5 = 25/5

x = 5

The side on a clip board appears to be a right triangle. The leg lengths are 2 millimeters and 2.1 millimeters and the hypotenuse is 2.9 millimeters. Is the side of the clip a right triangle?

Answers

Answer:

Yes, it is a right angle triangle

Step-by-step explanation:

Let leg lengths be y and z

Y = 2mm

Z = 2.1mm

Let x represent hypothenus

X = 2.9mm

To find out if it's a right angle triangle, we'll use pythagorean theorem since it's true for all right angle triangles I.e the square of the hypothenus is equal to the square of both sides(opposite and adjacent)

x² = y² + z²

x² = 2² + 2.1²

x² = 4 + 4.41

x² = 8.41

Take the square root of both sides

x = √(8.41)

x = 2.9mm

Therefore since the square of two other sides equal the square of the hypothenus, the side of the clip is a right angle triangle

Find the angle represented by x (rounded to the nearest tenth of a degree). A) 32.6° B) 36.4° C) 37.8° D) 38.7°

Answers

Answer:

The angle is 49.63°, approximately.

Step-by-step explanation:

In the image attached, you can observe that the angle we need to find is an acute angle of a right triangle, where its hypothenuse is 21 units long and its opposite leg is 16 units long.

Having these elements, we can use the sine trigonometric reason to find the angle.

[tex]sin(x)=\frac{opposite \ leg}{hypothenuse} =\frac{16}{21}\\ x=sin^{-1}(\frac{16}{21} ) \approx 49.63\°[/tex]

Therefore, the angle is 49.63°, approximately.

Fraction is a "number are expressed as quotient, where numerator is divided by denominator".

According to the question,

Faith has 25 sheets of colored paper. She plans to make 15 of the cards out red paper.

[tex]\frac{15}{25}[/tex] =  [tex]\frac{3}{5}[/tex]

5 - 3 =2

Fraction 5 parts of sheets is equal to 25, 3 parts of sheet is equal to 15.

Kiyo is designing a rectangular garden with a 2-ft wide path all the way around it. The length of the garden is 3 times as long as the width. Kiyo models the area of his garden and the path with the equation f(x) = (x + 2)(3x + 2). Explain Kiyo’s error

Answers

Answer:

The correct equation that models the area if x(3x) or 3x² where x is the width of the path

Step-by-step explanation:

Area of a rectangle = Length *Width

Width of the rectangular garden W = 2ft

If the length of the garden is 3 times as long as the width, then length = 3 * width i.e W = 3L

Since Area of the path A = L* W

A = (3W)W

A = 3W²

If the width is the same as x then

Area f(x) = (3x)(x)

According to kyle, the area of his path f(x) = (x + 2)(3x + 2) which is wrong because of kyle addition of 2 to each of the value of the length and width respectively which kyle shouldn't have added any value to the dimension to the garden

The system of equations that can be used to solve [tex]12x^3 - 5x = 2x ^2 + x + 6[/tex] [tex]y = 2x ^2 + x + 6[/tex] and [tex]y= 12x^3 - 5x[/tex]

The equation is given as:

[tex]12x^3 - 5x = 2x ^2 + x + 6[/tex]

Split the above equation into 2, and set both equations to 0

[tex]12x^3 - 5x = 0[/tex]

[tex]2x ^2 + x + 6 = 0[/tex]

Replace the "0" with y, in both equations

Rewrite the equations as:

[tex]y = 2x ^2 + x + 6[/tex]

[tex]y= 12x^3 - 5x[/tex]

Hence, [tex]y = 2x ^2 + x + 6[/tex] and [tex]y= 12x^3 - 5x[/tex] can be used to solve [tex]12x^3 - 5x = 2x ^2 + x + 6[/tex]
