The slope intercept form is .
Solution:
Given data: slope = and y-intercept = –1
y-intercept means (x, y) = (0, –1)
Equation of a line for slope intercept form:
Here, and
.
⇒

Do cross multiplication.
⇒
⇒
⇒
Divide both sides of the equation by 4.
⇒
⇒
Hence the slope intercept form is .
Answer: skin cells were not burned.
Step-by-step explanation:
<h3><u> The complete exercise is: Two percent of Sennie's skin cells were burned when she escaped from a fire. IfLet be "x" the number of Sennie's skin cells that were not burned when she escaped from the fire.
According the the data given in the exercise, you know that 2% represents of Sennie's skin cells that were burned. This means that the percent of her skin cells that were not burned is:
With this information you can write the following proportion:
Solving for "x", you get:
To express the result in Scientific notation, the decimal point must be after the first digit; then you must move the decimal point two places to the left:
Answer:
m∠ABC = 83°
Step-by-step explanation:
The angle ∠abc and ∠dbe are opposed by the vertex. By definition "<em>Two angles opposite the vertex are congruent or equal</em>"
So ∠abc = ∠dbe
Then, to solve this problem you must match both expressions and clear the variable x.
Now substitute x = 15 in the given expression for the angle ∠abc. (6x-7)
So, we have:
°
Finally, the angle is 83°
