y=5x+1 graph the equation

Answers

This is how you would graph y=5x+1

Just choose values for x like (-2,-1,0,1,2) then replace it in the equation. Ex. For -2 it would be y=5(-2)+1
Y=-9
So the point would be x=-2 and y=-9

Can someone help me with this umm math thingy

Answers

Answer:

1. The similar triangles are ΔXYZ and ΔPQR

The triangles are similar by the AA rule of similarity

2. The similar triangles ΔXYZ and ΔPQR cannot be assumed as being congruent because more information are required about the length of a pair of corresponding sides of both triangles

3. x = 17.5

4. x = 20

Step-by-step explanation:

1. The angles of triangle ΔXYZ are;

∠X = 32°, ∠Y = 84° and ∠Z = 180° - (84° + 32°) = 64°

The angles of triangle ΔPQR are;

∠P = 64°, ∠R = 32° and ∠Q = 180° - (64° + 32°) = 84°

The angles of triangle ΔABC are;

∠A = 64°, ∠C = 92° and ∠B = 180 - (92 + 64) = 24°

Therefore, the two similar triangles are ΔXYZ and ΔPQR

The triangles are similar based on Angle-Angle (AA) rule of similarity

2. The similar triangles ΔXYZ and ΔPQR cannot be assumed as being congruent because more information are required about the length of a pair of corresponding sides of both triangles

3. We have by corresponding triangles formed by the tree and Enzo as follows;

5 ft./(6 ft.)= x/(21 ft.)

∴ x = 21 ft.× (5 ft./6 ft.) = 17.5 ft.

x = 17.5 feet

4. By corresponding triangles, we have;

(35 ft.)/(40.5 ft.+ 54 ft.) = x ft./(54 ft.)

∴ x ft. = (54 ft.) × (35 ft.)/(40.5 ft.+ 54 ft.) = 54 ft. × (35 ft.)/(94.5 ft.) = 20 ft.

x ft. = 20 ft.

∴ x = 20

Josie wants to hang a “Happy Birthday” banner across the diagonal of a rectangular opening that has a width of 9 feet and a height of 12 feet.
How many inches long should the banner be?

Answers

If the answer is 29 then the correct formation of the equivalent answer would be 245

Length of banner is 15 feet

Given that;

Width of rectangle = 9 feet

Length of rectangle = 12 feet

Find:

Length of banner

Computation:

Length of banner = Length of diagonal

[tex]Length\ of\ diagonal = \sqrt{Length^2 + Width^2}\\\\ Length\ of\ diagonal = \sqrt{12^2 + 9^2}\\\\ Length\ of\ diagonal = \sqrt{144 + 81}\\\\ Length\ of\ diagonal = \sqrt{225}\\\\ Length\ of\ diagonal = 15 \ feet[/tex]

So,

Length of banner = 15 feet

Answer:

Step-by-step explanation:

(a + b) (a² - ab + b) = a*(a² - ab + b) + b(a² - ab + b)

= a*a² - a*ab +a*b + b*a² - b*ab + b*b
