help plzzzz !! thanks
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = 2, 3) and (x₂, y₂ ) = (0, - 1)
m = [tex]\frac{-1-3}{0-2}[/tex] = [tex]\frac{-4}{-2}[/tex] = 2
The line crosses the y- axis at (0, - 1 ) ⇒ c = - 1
y = 2x - 1 → C

Betsy is ordering prizes for a school fair. She must order 2 helium balloons for every 5 people and 3 stuffed animals for every 8 people. Organizers expect 120 people to attend the fair. TRUE OR FALSE: Betsy orders 48 helium BALLOONS
Answer:
True, she would need to order 48.
Step-by-step explanation:
If you divide the expected number of people (120) by the number of balloons per person (120 divided by 5) then multiply that by 2 you get 48.
Can somebody plz help answer these math questions correctly thx (only if u done this before) :3
WILL MARK BRAINLIEST WHOEVER ANSWERS THESE FIRST!!!
Answer:
Step-by-step explanation:
The sum of complementary angles equals to 90° while the sum of supplementary angles equals 180°.
The measure of the complementary angles will be:
19. 42°
= 90° - 42°
= 48°
20. 78°
= 90° - 78°
= 12°
21. 32°
= 90° - 32°
= 58°
22. 72°
= 90° - 72°
= 18°
22. 40°
= 90° - 40°
= 50°
23. 14°
= 90° - 14°
= 76°
The measure of the supplementary angles will be:
25. 36°
= 180° - 36°
= 144°
26. 124°
= 180° - 124°
= 56°
27. 85°
= 180° - 85°
= 95°
28. 84°
= 180° - 84°
= 96°
29. 153°
= 180° - 153°
= 27°
30. 176°
= 180° - 176°
= 4°
Note that the value of the complementary angles were gotten by deducting the angles given from 90° while the supplementary angles were gotten by deducting the values given from 180°.
In a sample of 1100 U.S. adults, 213 think that most celebrities are good role models. Two U.S. Adults are selected from this sample without replacement. Complete parts (a) through (c).
Answer:
a) 0.0374 , b) 0.6500 , c) 0.3500
Step-by-step explanation:
Pr (Both consider celebrities role models) = (213/1100) x (212/1099)
= 0.0374
Pr (None consider celebrities role models) = (887/1100) x (886/1099)
= 0.6500
Pr (atleast one consider celebrities role models) = 1 - Pr (None consider role models)
1 - 0.6500 = 0.3500

In rhombus MATH, find the value of x
if mZMAH=5x+12 and mZHAT=8x-12.
If the answer is 13.8, move to T
If the answer is 12, move to u
If the answer is 8, move to v
If the answer is 0, move to w
Answer:
m<MAH=5x+12
mZHAT=8x-12.=
m<MAH=mZHAT diagonal of rhombus bisect the angle
5x+12 =8x-12
12+12=8x-5x
24=3x
x=24/3=8 is your answer.
this is the required answer look it once

The tropical rainforest has acidic soil which is bad for plant growth; however, the Rainforest has the most biodiversity. Which abiotic factor increases the biodiversity of the rainforest?
Many of the plants in the rainforest are vines that grow up the trees and don’t need soil.
The Venus fly trap consumes insects to make up for the bad soil.
The days are short in the rainforest, so plants have less sunlight.
The temperature of the rainforest is warm all year round which is good for growing plants.
Answer:
Many of the plants in the rainforest are vines that grow up the trees and don’t need soil. :P

2x+2y=-2 y = x + 5 please hurry!
Answer:
2x+2y=x+5
(move the x next to the 2y)
= 2x+2y-x=5
(the x is negative because i moved it)
(collect the like terms)
= x+2y=5
(so the answer is...)
x+2y=5
