Answer:
x =112
Step-by-step explanation:
The sum of the angles of a triangle add to 180
Two angles are 34 and 34. Let the third angle be x
34+34+x = 180
Combine like terms
68+x = 180
Subtract 68 from each side
68-68 +x = 180-68
x =112
Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
x = −1 ± i√2
There's no real solutions
So this one is pretty easy actually when x= a number you automatically know it'll be a vertical line cutting through the x axis. So for this problem (x=5) the line will be vertical and cut through the x axis. Hope this helps!
Answer:
14 apples, 10 bananas
Step-by-step explanation:
.07 * 12 = .84 (12 apples at 7 pence/per = 84 pence)
5 - .84 = 4.16 (4.16 pound remaining)
4.16/.4 = 10.4 (you can buy 10 bananas with 4.16 pounds, with .16 pence remaining)
.16 / .7 = 2.3 (you can buy two more apples with 16 pence)
Hope this helps.
Answer:
y = 5x - 5
Step-by-step explanation:
It appears that the graph intersects the y-axis at (0, -5). This point is the y-intercept of the line.
As we move from (0, -5) to the point (2, 5), x increases by 2 and y increases by 10. Thus, the slope of the line through these two points is
m = rise / run = 10 / 2 = 5.
The slope-intercept form of the equation of a straight line, y = mx + b, becomes y = 5x - 5
