Answer: y-int ( 0, 0.4 ) x-int ( 0.3, 0 )
Step-by-step explanation:
Given in the graph
X axis and Y axis.
Answer:
k=86
Step-by-step explanation:
Answer:
y = -(2/3)x + 3
C
Step-by-step explanation:
The slope of the equation that was given is - 2/3
The slope in a slope intercept equation is the number in front of the x when the value of the number in front of the y = 1 and x and y are on opposite sides of the equal sign. Let's translate that.
The original equation is y = -(2/3)x + 5/3
- y and x have to be on opposite sides of the equal sign [They are]
- The slope is the number in front of the x. That's (-2/3). That makes A incorrect.
Now you need to use the given point
The point is (-3 , 5) Put this into the equation that you have so far
y = (-2/3)x + b
y = 5
x = -3
5 = (-2/3)(-3/1) + b Substitute in the givens
5 = (-2 * -3)/3 + b Multiply -2 * - 3 = 6
5 = 6/3 + b Divide the 6 by 3
5 = 2 + b Divide
5 - 2 = b Subtract 2 from both sides
3 = b Switch sides
b = 3
Answer y = (-2/3)x + 3 or C
Okay, so with the link we can tell this:
flour and baking soda are equal ratios
salt is one half the ratio of flour/baking soda
A: correct
flour and baking soda as equal ratios
B: incorrect
salt is at an incorrect ratio to flour
C: correct
salt is at a correct ratio to baking soda
D: incorrect
salt is at an incorrect ratio to baking soda
E: correct
baking soda is at a correct ratio to salt
answers: A, C , E
Let us assume then that the center is the origin. If the major axis is 18, then a = 9 and a^2=81. If the minor axis is 16, then b = 8 and b^2=64. Now you can write the equation. Remember that this ellipse is vertical and so a^2 goes under y^2
