First let us find the slope between the two points.
Slope = Change in y / Change in x.
(3, 6) and (8, 4) compares to (x₁, y₁) and (x₂, y₂)
Slope = (y₂ - y₁) / (x₂ - x₁) = (4 - 6) / (8 - 3) = -2/5
Slope m = -2/5= -0.4
Using y = mx + c, using point (3, 6)
y = -0.4x + c
6 = -0.4*3 + c
6 = -1.2 + c
6 + 1.2 = c
7.2 = c
c = 7.2
Equation = : y = -0.4x +c
y = -0.4x + 7.2
y = -4/10 + 72/10
10y = -4x + 72
5y = -2x + 36
Equation =: 5y = -2x + 36
Hope this explains it.
Answer:
A and C is true statements
Answer
396 miles and $28.71
The cost per child per child is $10 more at Mr Bob's buffet than it is at Sally's pizza safari.
Answer: Option 3.
<u>Explanation:</u>
According to the data and the information that has been given in the question, the cost of four children for this birthday party at Mr Bob is $60. But the cost of hosting a birthday party at Mr Sally is $50 which is the cost of four children.
So this tells us that the cost of hosting a birthday party is expensive at Mr Bob when compared to the cost of hosting a party at Mr Sally. It is $10 more than Mr Sally.
Responder:
- 30 ° C
Explicação passo a passo:
Dado que :
A temperatura diminui 1 ° para cada 200 m afastados da superfície terrestre
Temperatura na superfície da terra = 20 ° C
Temperatura atmosférica a uma altura de 10 km de. Superfície Terrestre :
Queda de temperatura para uma altura de 10 km de distância;
10km = 10 * 1000 = 10.000 m
1 * (10000/200)
1 * 50
= 50 ° C
Portanto ;
Temperatura da superfície terrestre - 50 ° C
20 ° C - 50 ° C
= - 30 ° C
