Answer:
x = 11
Step-by-step explanation:
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.
then 6/(6 + 48) = 5/(5 + 3x + 7)
6(3x + 12) = 5(54)
18x + 72 = 270
18x = 198
x = 11
Answer:
1/-2 is the slope
Step-by-step explanation:
I think the statement is missing in the question.
Let's assume it to be :
<span>Describe a situation that can be represented by the expression 4(X-2)
According to that we can say:
A functions is define by Four times the difference of a number X an</span><span>d</span> two.
Hope it helps.
Answer:
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)
The equation of the given line is
9x+7y=4
7y = - 9x + 4
y = -9x/7 + 4/7
Comparing with the slope intercept form, slope = - 9/7
If the line passing through the given point is perpendicular to the given line, it means its slope is the negative reciprocal of the slope of the given line.
Therefore, the slope of the line passing through (7,-4) is 7/9
To determine the intercept, we would substitute m = 7/9, x = 7 and y = -4 into y = mx + c. It becomes
- 4 = 7/9×7 + c = 49/9 + c
c = - 4 - 49/9 = -85/9
The equation becomes
y = 7x/9 - 85/9
Ths solubility curve is used to show the amount of salt dissolved (solubility).
<h3>What is the solubility curve?</h3>
The solubility curve is a depiction of the solubility of a substance plotted against its temperature. It can be used most times to show the solubility of a susbtance at different temperatures. This question is incomplete hence so we can not be able to obtain the solubility of the salt at this temperature.
If the solubility curve has been shown in the graph, then we can be able to obtain the solubility of the salt from the data shown on the plot.
