Answer:
Justin is 5 yrs old
Step-by-step explanation:
make an equation out of it. Let x be Justin's age
1/4(12)+2=x
simplify
3+2=x
x=5
Justin's age is 5 years.
What is linear equation in one variable?The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.
According to the given question
Justin is 2 years older than 1/4 of his brother's age.
Let the age of Justin be x years.
Also, Justin's brother age is 12 years.
Therefore,
The age pf Justin is given by
[tex]x = 2 + \frac{1}{4}(12)[/tex]
solve the above linear equation
⇒ x = 2 + 3
⇒ x = 5 years
Hence, Justin's age is 5 years.

which expression below me is equivalent to -3x+5(x+2)?
A.2x+2
B.-x+2
C.2x+10
D.-8x+10
Answer:
C)
Step-by-step explanation:
First use distributive property: a(b +c) =a*b +a*c
-3x + 5(x +2) = -3x + 5*x +5*2
= -3x + 5x + 10 {Combine like terms}
= 2x + 10
(-3x) and 5x are like terms

Enter the number that makes the equation true
Answer:
80
Step-by-step explanation:
First of all, before you do anything to compute the answer, you can see that there is (–13/100) on both sides of the equation. You can cancel them out, since they're the same thing.
Now, you're left with:
[tex]0.8 = \frac{}{100}[/tex]
This is also read as 0.8 is the same thing as [how many] hundredths.
You should know that 0.8 = eight tenths.
So if you move the decimal point right once, you'll get:
0.80
Which is also eighty hundredths.
Your answer would be:
[tex]0.8 = \frac{80}{100}[/tex]
which is 80.
To check your answer, you can also do:
80/100
Because the fraction bar can also be read as "divided by."
You will get 0.8.

Find the slope of the line on the graph below
Answer:
[tex]\frac{6}{5}[/tex]
Step-by-step explanation:
The slope is [tex]\frac{6}{5}[/tex] because rise/run. You rise up on the graph 6 units, and run 5 units to the right (if the graph went to the left), then your slope would be negative.
Another way to double check this is using the slope formula: [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex].
(-3, -3) is x1, y1. & (2, 3) is x2, y2.
So, plugging that into the formula, we get:
[tex]\frac{3-(-3)}{2-(-3)}[/tex] = [tex]\frac{6}{5}[/tex].
Hope that this helped. Have a good day! ☺

كيفية حساب cos a و tan a بحيث sin a يساوي 1على 2
Answer:
uh i dont know
Step-by-step explanation:
Look at the graph.
On a coordinate plane, a graph increases through (negative 1, 4), levels off at (0, negative 3), and then increases up through (2, 5).
Leslie analyzed the graph to determine if the function it represents is linear or non-linear. First she found three points on the graph to be (–1, –4), (0, -3), and (2, 5). Next, she determined the rate of change between the points (–1, –4) and (0, -3) to be StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction = StartFraction 1 Over 1 EndFraction = 1. and the rate of change between the points (0, -3) and (2, 5) to be StartFraction 5 minus (negative 3) Over 2 minus 0 EndFraction = StartFraction 8 Over 2 EndFraction = 4. Finally, she concluded that since the rate of change is not constant, the function must be linear. Why is Leslie wrong?
The points (–1, –4), (0, –3), and (2, 5) are not all on the graph.
The expressions StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction and StartFraction negative 3 minus (negative 5) Over 2 minus 0 EndFraction both equal 1.
She miscalculated the rates of change.
Her conclusion is wrong. If the rate of change is not constant, then the function cannot be linear.

Simplify the expression: 9-2X + 8 + x + 5x
Answer:
4x + 17
Step-by-step explanation:
9 - 2x + 8+ x + 5x
Add/Subtract the values with variables together and the same case for the values without any variables.
5x + x - 2x = 4x
9 + 8 = 17
So you'll end up with the following,
4x + 17

A scuba diver dives 243 feet into the ocean and then swims up 156
feet. What integer represents her final position relative to where
she started?
Answer:
Her final position would stop at -87.
Step-by-step explanation:
As she dove 243 feet into the ocean, that means she went down. Therefore she's currently at -243, however she swam up 156 feet ending her up at -87. If that was kinda complicated, then use -243+156 and you'll get -87.

Answer:
$47,682.78
Step-by-step explanation:
future value: F = $64,700
present value: P = x
annual interest rate: r = 2.18%
compounding periods per year: n = 365
[tex] F = P(1 + \dfrac{r}{n})^{nt} [/tex]
[tex] 64,700 = P(1 + \dfrac{0.0218}{365})^{365 \times 14} [/tex]
[tex] 64,700 = P(1 + 0.0000597260274)^{5110} [/tex]
[tex] 64,700 = P(1.0000597260274)^{5110} [/tex]
[tex] 64,700 = P(1.356883989) [/tex]
[tex] P = 47,682.78 [/tex]
