Answer:
a1= -19, a2= 9
Step-by-step explanation:
step 1. Add 5 + 9 /a +5/ = 9+5
step 2. Use the absolute value definition, rewrite the absolute value equation as two separate equations. a+5=14 a+5= -14
step 3. a=9 a+5= -14
step 4. a= 9 a= -19 the equation has 2 solutions
a¹ = - 19, a²= 9
Answer:
A: 15%
Step-by-step explanation:
First test:
15 ÷ 20 = 0.75
0.75 * 100 = 75%
Second Test:
18 ÷ 20 = 0.9
0.9 * 100 = 90%
90% - 75% = 15%
Answer:
1a the square root of 37
1b the same as a
2 y=3x+2
Step-by-step explanation:
a and b use the distance formula
for number 2 use rise over run to find the slope and find where the line intersects to find the y intercept.
Hope this helps :)
5m+2(m+8)+3
5m+2m+16+3
7m+19
102
the angles are alternate so they add up to 180
180-78=102
hope this helps :)
if you need me to explain more just let me know :)
