Answer:
x = 20°, y = 70° see image
Step-by-step explanation:
Use the bottom, lower, short wide triangle first. It has marks on it to show that two of the sides are the same length. That means that the opposite angles are the same. One is marked x, so the other is also x. There is a 40° angle given, along the same line right next to it has to be 140°. We'll use that one.
Also, the angles in a triangle add up to 180°.
x° + x° + 140° = 180°
See image for calculations.
Then we use the whole entire triangle. It has a 90° angle and the 20° (for x, that we just found) and y. We'll use that to find y.
90° + y + 20° = 180°
See image for calculations.
Answer:
(3a-7) (2a-1) is the answer
Step-by-step explanation:
Answer:
x=2 and y= -2
Step-by-step explanation:
(x,y)=(3-1,2-4)
(x,y)=(2,-2)
x=2
y= -2
Answer:
y = 3/2 x + 3
Step-by-step explanation:
-9x + 6y = 18 is in standard form (ax + by = c).
Slope-intercept form isolates the "y" variable. It looks like this:
y = mx + b
Move anything that's not "y" to the right side. Move things in reverse BEDMAS order, using reverse operations of what you want to move.
Move -9x by doing +9x to both sides
Simplify. -9x + 9x will cancel out.
Move the "6" that multiplies with "y".
Divide each term by 6.
"y" is isolated. Simplify the rest.
Rearrange to match slope-intercept form.
Answer:
5th month
Step-by-step explanation:
the relationship between the second and third month is that the 2nd month's salary was multiplied 4 to get the third month's salary
therefore the salaries for the next months will be
4th month=Gh¢12800.00
5th month=Gh¢51,200.00 which exceeds 20,000
