Simplify the expression

Mathematics
1 answer:
bearhunter [10]3 years ago
7 0
First we want to simplify the denominator
\frac{1}{4} - \frac{5}{2}

to subtract, we convert 5/2 to have a denominator of 4
\frac{1}{4} - \frac{10}{4}
- \frac{9}{4}

now we can put this back into the original problem
\frac{4}{ - \frac{9}{4} }
this equation can also be read as
4 \div - \frac{9}{4}

when dividing, we flip the right side and switch to multiplication
\frac{4}{1} \times - \frac{4}{9} = - \frac{16}{9}

answer = - \frac{16}{9}

Select ALL the correct answers.<br> Select all functions that have a y-intercept of (0,5).
otez555 [7]
1.) f(x)=7(b)^x-2
x=0→f(0)=7(b)^0-2=7(1)-2=7-2→f(0)=5→(x,f(x))=(0,5) Ok

2.) f(x)=-3(b)^x-5
x=0→f(0)=-3(b)^0-5=-3(1)-5=-3-5→f(0)=-8→(x,f(x))=(0,-8) No

3.) f(x)=5(b)^x-1
x=0→f(0)=5(b)^0-1=5(1)-1=5-1→f(0)=4→(x,f(x))=(0,4) No

4.) f(x)=-5(b)^x+10
x=0→f(0)=-5(b)^0+10=-5(1)+10=-5+10→f(0)=5→(x,f(x))=(0,5) Ok

5.) f(x)=2(b)^x+5
x=0→f(0)=2(b)^0+5=2(1)+5=2+5→f(0)=7→(x,f(x))=(0,7) No

Answers:
First option: f(x)=7(b)^x-2
Fourth option: f(x)=-5(b)^x+10

What is 0.002 1/10 of
ki77a [65]
<span>0.002 1/10 of what
=> 1/10a = 0.002
=> Now, let’s multiply both sides with 10 to find the answer since we’re looking for the 1/10 of what number.
=> 10 x 1/10 a = 10 x 0.002
=>  a = 0.02

Thus, 0.002 is the 1/10 of 0.02 number.
let’s check if we have a correct answer.
To check just do the other way around, Divide our answer by 10.
=> 0.02 / 10
=> 0.002
Therefore, our answer is correct
