Answer:
The answer is x + 4y = 7
Equation of a line is y = mx + c
Where m is the slope
c is the y intercept
Slope of the line between the points
(-1, 2) and (3, 1) is
Slope = 1-2/ 3+1 = - 1/4
Equation of the line using point
(-1, 2) is
y - 2 = -1/4(x + 1)
4y - 8 = - x - 1
x + 4y = 7
Hope this helps you
Answer:
The equation of the line tangent to the graph of f at x = -1 is
.
Step-by-step explanation:
From Analytical Geometry we know that the tangent line is a first order polynomial, whose form is defined by:
(1)
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Slope, dimensionless.
- Intercept, dimensionless.
The slope of the tangent line at
is:
(2)


If we know that
,
and
, then the intercept of the equation of the line is:



The equation of the line tangent to the graph of f at x = -1 is
.
Answer:
B; 50%
Step-by-step explanation:
Here, we want to calculate the percentage of women that will not fit in the driver’s seat
We proceed as follows;
We start with calculating the z-score of this;
That would be ;
(x-mean)/SD
in this case;
x = 34 inches
mean = 34 inches
SD = 1.4 inches
Thus, we have that;
(34-34)/1.4 = 0/1.4 = 0
when z-score is 0, we are at the center of the distribution
A z-score of 0 corresponds to exactly 50%
12+6=18 18+18=36 total coins.
12 quarters:36 coins.
To simplify divide each side by 12.
12/12=1 36/12=3
The simplified ratio is 1:3.
Therefore the answer is B.
Hope this helps! (:
