So first distribute the -.
-8= -x-4
+4 +4
-4=-x and divide -1 on both sides. This becomes x=4.
Answer:
A
Step-by-step explanation:
Given
x² - 25 = 0 ( add 25 to both sides )
x² = 25 ( take the square root of both sides )
x = ± 
= ± 5
Solutions are x = 5 and x = - 5
Answer:
Amplitude =1
Step-by-step explanation:
Given function is 
.
Now we need to find about what is the amplitude of the given function .
To find that let's compare given equation with standard equation 
. We get:
a=1
We know that amplitude of the function is given by the value of |a|.
Hence amplitude of the given function = |a|= |1|=1
Hi there! So, if $36.40 in interest was in her account after 3.5 years, we can divide both numbers. 36.4/3.5 is 10.4. That's $10.40 in interest per year, with the rate of simple interest being 6.5%. But to make it easier, we can divide 10.40 by 6.5 to find the unit rate. When you divide both number, you get 1.6. 1% of the initial amount is $1.60. Percents are parts of 100. Multiply 1.6 by 100 to get 160. Now, let's divide the interest earned yearly by initial amount to see if it works. 10.4/160 is 0.065 or ^.5% when turned into decimal form. there. Safiya's initial deposit in the bank was $160.
Answer:
Bradford T. answered • 11/08/20. Tutor. 5 (6). Retired Engineer / Upper level math instructor ... You need to first subtract 4 from both sides of the equation and see if you ... (x +3/2)(x+1/2) = x2 + x/2 + 3x/2 + 3/4 = x2 + 2x + 3/4 = 0 --> 4x2 + 8x + 3 ... You can plug them back into your original question to check.
