Answer:
y = x + 4
Step-by-step explanation:
AB is a base of trapezoid.
In trapezoid , one pair of sides are parallel.
In given trapezoid , CD is parallel to AB.
When two lines are parallel then, slopes of lines are equal.
Therefore , slope of CD=1
The equation of line with slope 1 and passing through the point C (4,8) is given by Substitute the values then we get
The equation of line with slope 1 and passing through the point C (4,8) is given by
The equation of line with slope 1 and passing through the point C (4,8) is given by
Answer:
x=5
Step-by-step explanation:
Formulate and substitute:d=4v
Rearrange unknown terms to the left side of the equation: 4x=27-7
Calculate the sum or difference: 4x=20
Divide both sides of the equation by the coefficient of variable: x=20÷4
Calculate the product or quotient: x=5
So the Answer is: x=5
Answer:
Larger angle: 80 degrees
Smaller angle: 10 degrees
Step-by-step explanation:
complementary angles = two angles that add up to 90 degrees
x = larger angle
x + x - 70 = 90 Add like terms
2x - 70 = 90 Add 70 on both sides
2x = 160 Isolate the variable by dividing 2 on both sides
x = 80
x = larger angle , 80 degrees
x - 70 = smaller angle , 10 degree

<span>18x+9xy is correct all Roots are to x=0 and y=-2
(9x⋅2)+(9x⋅y) is correct </span>Roots are to x=0 and y=-2
Answer:
1a) 1141/660
3/5 + 6/11 +7/12
find the LCM of the denominators
the LCM of 5,11,12 is 660
after finding the LCM divide it with the denominator.
after dividing 660 by 5 i get 132. So i need to multiply it with 3. Now, i got 396. Do the same with the rest of the numbers.
u will get smth like this: 396+360+385/660
and the final answer will be1141/660.
b) 71/40
c) 211/28
d) 103/20
