9 and 8 are the two numbers.
9 + 8 = 17
9 - 8 = 1
Answer:
x-intercept ( 18/5, 0) y-intercept: (0, -2)
Step-by-step explanation:
-5x+9y= -18
Find x-intercept by letting y = 0.
-5x + 9*0 = -18
-5x = -18
x = 18/5
Find y-intercept by letting x=0
-5*0 +9y = -18
9y =-18
y = -2
Answers:
x intercept is (-7.5, 0)
y intercept is (0, 5.5)
=========================
How to get these answers:
Simply look at where the graph crosses the x axis to determine the x intercept. This is directly halfway between the -8 and -7, so the line crosses through -7.5 on the x axis meaning that the x intercept is located at (-7.5, 0)
Similarly, the y intercept is (0, 5.5) as it crosses exactly halfway between the 5 and 6 on the y axis.
Any point is of the form (x,y)
The x intercept always has y = 0. The y intercept always has x = 0.
Answer:
Step-by-step explanation:
Get rid of the parenthesis then combine like terms
Answer:
The measure of the angles:
24° and 66°
Step-by-step explanation:
Complementary angles sum 90°
then:
(3x + 3) + (10x-4) = 90
3x + 10x + 3 - 4 = 90
13x - 1 = 90
13x = 90+1
13x = 91
x = 91/13
x = 7°
then:
3x+3 = 3*7 + 3 = 21+3 = 24°
10x - 4 = 10*7 - 4 = 70 - 4 = 66°
Check:
66° + 24° = 90°
