Answer:
1 solution --> y=-13/2
Step-by-step explanation:
7(y+3)=5y+8
7y +21=5y+8
2y=8-21
2y=-13
y=-13/2
<u>X - Intercept</u>
x + 3y + 2z = 6
x + 3(0) + 2(0) = 6
x + 0 + 0 = 6
x + 0 = 6
<u> - 0 - 0</u>
x = 6
X - Intercept: (6, 0, 0)
<u>Y - Intercept</u>
x + 3y + 2z = 6
0 + 3y + 2(0) = 6
0 + 3y + 0 = 6
0 + 0 + 3y = 6
0 + 3y = 6
<u>- 0 - 0</u>
<u>3y</u> = <u>6</u>
3 3
y = 2
Y - Intercept: (0, 2, 0)
<u>Z - Intercept</u>
x + 3y + 2z = 6
0 + 3(0) 2z = 6
0 + 0 + 2z = 6
0 + 2z = 6
<u>- 0 - 0</u>
<u>2z</u> = <u>6</u>
2 2
z = 3
Z - Intercept: (0, 0, 3)
<u>Volume of the X - Intercept, Y - Intercept, and Z - Intercept</u>
V = ¹/₃(¹/₂lwh)
V = ¹/₃(¹/₂(6)(2)(3))
V = ¹/₃(¹/₂(12)(3))
V = ¹/₃(¹/₂(36))
V = ¹/₃(18)
V = 6 u³
C) 46,200
This is because the 1,900 represents the increase in population in x years.
The expressions that show different ways to rewrite
are ...
a. (4^x * 4^x) / 4^x
b. 4^x
c. (16 / 4)^x
Answer:
5) x=7
6) x=14
7) x=22
8) x=27
Step-by-step explanation:
Please see attached picture for full solution.
If 2 straight lines intersect, then the 2 angles opposite each other are equal.
