Answer:
A
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 )
y = - 3x + 4 is in this form
with y- intercept c = 4 → A
To make the sure the results did not happen by chance, the coach can ensure that the protein bars are the only difference between the two groups. For example, he can make sure that both groups are drinking the same amounts of water and getting in the same amount of practice; that way, he will be able to determine that one group is performing better due to the protein bars only. Also, the coach can repeat this experiment multiple times to make sure that the results weren't a random, one-time thing.
Answer:
(3x + 4)(x - 1)
Step-by-step explanation:
3x^2 + x - 4
use middle term break method
we need two number which gives 12 when multiplied and 1 when subtracted
3x^2 + (4 - 3)x - 4
3x^2 + 4x - 3x - 4
x(3x + 4) -1(3x + 4)
(3x + 4)(x - 1)
Please consider the attached graph.
We have been given that there are two different models of the same triangular-shaped garden. The height of the model on the left is 14 cm. We are asked to find the height of the model.
First of all, we will convert 14 cm into feet.
We can see that model on left side has a scale of 1 cm is equal to 15 feet.
14 cm = 14×15 feet = 210 feet.
We can see that model on the right side has a scale of 1 cm is equal to 7.5 feet.
Since both models represent same triangular-shaped garden, so the actual height for the both models will be same.
Now we need to convert actual height of 210 feet into inches using 2nd scale.
Therefore, the height of the model on right is 28 inches.
