Multiply 7.22 onto 10b and -3
new equation - 72.2b-21.66=7b-14
add 21.66 onto -14
new equation - 72.2b=7b+7.66
subtract 7b from 72.2
new equation: 65.2b=7.66
divide 65.2 from b
new equation: b=7.66/65.2
final answer: b=0.117
Answer:
y = -2/3 x + 25/3
Step-by-step explanation:
The slope = (y_2 - y_1) / (x_2 - x_1) = (9 - 7) / (-1 - 2) = -2/3.
Our equation needs to be in y = mx + b form.
We can plug in (2, 7) as our (x, y) and find b:
7 = -2/3 (2) + b
b = 7 + 4/3 = 25 / 3.
Therefore, our equation is y = -2/3 x + 25/3
Answer:
Step-by-step explanation:
Remark
The solution to this is to add the two vertically opposite arcs and take 1/2 of the result to get the intersecting angle of the chords.
Solution
<x = 1/2 (arc measure of 116 + 74)
<x = 1/2 (190)
<x = 95
Answer:
X=4
Step-by-step explanation:
2÷\frac{1}{2}=4
Because QRST is a rectangle, that means all of the angles must be a right angle, which are 90 degrees. Using this information, solve the expression by creating an equation that lets angle S = 90.
90 = 7x + 55
35 = 7x
x = 5
