60%. You count how many total (15) and then how many got below a 90 (9) and then divide 9 by 15.
Opposite sides of a parallelogram are equal lengths, so ...
... AB = CD
... 6x +30 = 2y -10
and
... BC = AD
... 2x -5 = y -35
_____
The equations can be put in standard form to get
... 3x -y = -20
... 2x -y = -30
Subtracting the second from the first, we get
... x = 10
Solving for y, we have
... y = 2x+30 = 2·10 +30 = 50
The values of x and y are x=10, y=50.
_____
AB = 6x+30 = 90
BC = 2x-5 = 15
Answer:
the slope is the coefficient of x= ⅕
intercept in x-axis → y=0 → f(x) = 0 → ⅕x -5 = 0 → ⅕x = 5 →x = 25 (25,0)
intercept in y axis : x= 0 → f(x) = ⅕(0) -5 = -5
(0,-5)
Answer:
1.0
Step-by-step explanation:
To round to the nearest tenth, look at the number in the hundredths place. (the second digit after the decimal point) If the number is 0-4, the number in the tenths place (first digit after decimal point) stays the same. If the number is 5-9, add 1 to the digit in the tenths place. Since it's 2 in this problem, the tenths digit stays the same: 1.0
Set both of the equations on the inside of the parentheses equal to zero.
2x - 1 = 0
X + 3 = 0
Now solve for x in both equations
X = 1/2
X = -3
