Well the line in the plane is Line AB. To find the name of a plane, we cannot use the points that form a straight line. The name of the plane must contain 3 points, so the name of the plane is plane ABD. So our answer would be A. Line AB and Plane ABD. Hope I helped!

1. (7 , 0) and (11 , 3) → B and D

substitute each coordinate point into the left side of the equation and if equal to 21 then it is a solution.

( 7 , 0) → (3 × 7) - ( 4× 0)  = 21 - 0 = 21  

(11 , 3) → (3 × 11 )  - ( 4 × 3) = 33 - 12 = 21

2. ( 2 , - 9 ) is a solution to the equation

substitute the coordinates into the equation and if equal to 13 the it is the solution.

(2 , - 9 ) → (5 × 2 ) - (-9)/3 = 10 + 9/3 = 10 + 3 = 13

(3 , - 6) → (5 × 3) - (- 6)/3 = 15 + 6/3 = 15 + 2 = 17

thus (2 , -9 ) is the solution

4. x- intercept = (- 45 , 0)

to find the x- intercept let y = 0

1/3 x + 0 = - 15

1/3x = - 15

multiply both sides by 3

x = 3 × - 15 = - 45

thus x -intercept = ( - 45 , 0)

Over time, Bailey has buried 6 large bones and 9 small bones in a hole. What is the ratio of small bones to large bones in the h
Wewaii [24]

Answer:

3:2

Step-by-step explanation:

to write a ratio, we can do ?:? in order. for example, 5 big shops to 10 small shops would be 5:10 (we are going to simplify it later) You always have to put the ratio numbers in order like they are in the question. In this case, small bones : big bones. We get 9:6. We can then divide both sides by a common factor, in this case 3. The end result is 3:2. Hope this helps!

Tresset [83]

Answer:

1\frac{1}{3} cups of flour.

Step-by-step explanation:

Given that:

w is the number of cups of water to be mixed with flour for making tortillas.

f is the number of cups of flour to be mixed with water for making tortillas.

Relation between w and f is given by the equation:

w=0.75f

To find:

Number of cups of flour to be added if number of cups of water to be used is 1.

Solution:

We are given an equation with two variables.

Value of one variable is given and we have to find the value of other variable.

1=0.75f\\\Rightarrow f = \dfrac{1}{0.75}\\\Rightarrow f = 1.33

Number of cups of flour to be added = 1\frac{1}{3}
