Step-by-step explanation:
Mike's current age, be M
Then Brandon's is: M - 27
Also, M = 4(M - 27)

Is y a function of x ?
Answer:
We know that y is a function of x because for each x-coordinate there is exactly one y-coordinate. If we draw a vertical line across the plot of the function, it only intersects the function once for each value of x. That is true no matter where the line is drawn.

Answer:
[tex] 30\: m^2 [/tex]
Step-by-step explanation:
For triangle:
Base = (4 + 3 +1) m = 8 m
Height = 9 m
For rectangle:
Length = 3 m
width = 2 m
Area of shaded region = Area of triangle - Area of rectangle
[tex]= \frac{1}{2}\times base\times height-length \times width \\\\= \frac{1}{2} \times (4 + 3 + 1) \times 9 - 3 \times 2 \\ \\ = \frac{1}{2} \times 8 \times 9 - 6 \\ \\ = 4 \times 9 - 6 \\ = 36 - 6 \\ = 30 \: {m}^{2} [/tex]

What is the value of (16^3/2)^1/2 256 8 4096 64
Answer:
8
Step-by-step explanation:
(16^3/2)^1/2
We know that a^ b^c = a^(b*c)
16 ^(3/2*1/2)
16 ^3/4
Now rewriting 16 as 2^4
2^4^3/4
2 ^ (4*3/4)

Mardi received an inheritance of $40,000. She invested part at 9% and the rest at 12%. Her total annual income from the investments was $3900. Find the amount she invested at 9%
Answer:
She invested $30,000 at 9%
Step-by-step explanation:
Let the amount invested per percentage be $x and $y respectively
Total investment is 40,000
This means that;
x + y = 40,000 ••••••••••(i)
Now for her income;
9/100 * x = 9x/100
for the 12% = 12/100 * y = 12y/100
Now;
9x/100 + 12y/100 = 3,900
9x + 12y = 390000 •••••••••(ii)
we solve both simultaneously
From i, y = 40,000-x
Substitute this into ii
9x + 12(40,000-x) = 390,000
9x + 480,000-12x = 390,000
3x = 480,000-390,0000
3x = 90,000
x = 90,000/3
x = $30,000

The formula for calculating the equation of a line is expressed as:
[tex]y=mx+b[/tex]
m is the slope
b is the y-intercept
For table 1,
Get the slope:
[tex]Slope=\frac{3-3}{3-2}\\Slope =\frac{0}{1} \\Slope =0[/tex]
Use the coordinate (-2, 3) and m = 0 to get the value of "b"
[tex]y=mx+b\\3 = 0(-2) + b\\b = 3[/tex]
The required function for table 1 is f(x) = 3
For table 2:
Get the slope:
[tex]Slope=\frac{0-1}{3-2}\\Slope =\frac{-1}{1} \\Slope =-1[/tex]
Use the coordinate (-2, 4) and m = -1 to get the value of "b"
[tex]y=mx+b\\4 = -1(-2) + b\\b = 4-2\\b=2[/tex]
The required function for table 2 is g(x) = -x + 2
If the function f(x) = g(x), hence:
-x + 2 = 3
-x = 3 - 2
-x = 1
x = -1
Hence the input value for which f(x) = g(x) is true is -1

Give 2 different ways to show that the equation does not have any solutions. One way must be solving algebraically, and the other way must be by graphing.
Answer:
The answer to this question can be described as follows:
Step-by-step explanation:
Given equation:
[tex]\bold{0.5x-7= \sqrt{(-5x+29)}}[/tex]
As in the given question the two ways to solve the equation can be defined as follows:
First way:
Let square the above-given equation then we will get:
[tex]\to (0.5x-7)^2= (\sqrt{(-5x+29)})^2\\\\\to (0.5x)^2 +7^2-2\times 0.5x\times 7= -5x+29\\\\\to 0.25x^2 +49- 7x= -5x+29\\\\\to 0.25x^2 - 7x+5x +49-29=0\\\\\to 0.25x^2 - 2x+20=0\\\\[/tex]
The calculated equation doesn't have any like term that's why it can't be factorised.

y = –5x + 30 x = 10 What is the solution to the system of equations? (–20, 10) (10, –20) (10, 4) (4, 10)
Answer:
(10, - 20 )
Step-by-step explanation:
Given the 2 equations
y = - 5x + 30 → (1)
x = 10 → (2)
Since the value of x is given substitute x = 10 into (1) for y
y = - 5(10) + 30 = - 50 + 30 = - 20
Solution is (10, - 20 )
Answer:
(10, -20)
Step-by-step explanation:
y = –5x + 30
x = 10
------
x=10 ⇒ y= -5*10+30= -20
Then solution is (10, -20)

Can someone help me with this ASAP please 50 points!!!
Answer:
a = 17 sqrt(2)
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opposite / hypotenuse
sin 45 = 17/a
Multiply each side by a
a sin 45 = 17
Divide each side by sin 45
a = 17 / sin 45
a = 17 / ( 1 / sqrt(2))
a = 17 sqrt(2)
The International Business Club starts the school year with $250.50 in their account. They spend $35 each month on activities. The Future Agricultural Leaders Club starts with $300 and spends $45.25 each month.
Answer:
250.5 - 35m = 300 - 45.25m
Complete question:
Which equation can be used to find m, the number of months it will take for both accounts to have the same amount of money?
250.5 + 35m = 300 + 45.25m
250.5 – 35m = 300 – 45.25m
250.5m – 35 = 300m – 45.25
250.5m + 35 = 300m + 45.25
Step-by-step explanation:
For The International Business Club: y = 250.50 - 35m,
For The Future Agricultural Leaders Club: y = 300 - 45.25m.
So the answer is 250.5 - 35m = 300 - 45.25m
250.5 – 35m = 300 – 45.25m
Explanation:
It's this one because the initial for international Business Club is $250.50 and their monthly spending is $35, and for Future Agricultural Leaders Club their initial is $300 and their monthly spending is $45.25
So, the equation would be 250.5 – 35m = 300 – 45.25m

Answer:
x(3+4)=4(x+3), (x+2)+5(x-1)=3(x+3)
Step-by-step explanation:
x(3+4)=4(x+3)
3x+4x=4x+12
7x=4x+12
Subtract 4x by both sides
3x=12
Divide 3 by both sides to get x=4
4x+5=3(x+2)
4x+5=3x+6
Combine Like terms
1x+5=6
Subtract 5 from both sides
x=1
(x+2)+5(x-1)=3(x+3)

find the values of a, b and c in the equation below (x^5yz^4)^3/x^3yz= x^a y^b z^c
Answer: a = 12, b = 2, c = 11
Step-by-step explanation:
Using exponent rules we can distribute the exponent of 3 to the xyz.
This results in the numerator now being. [tex]x^{5*3}+y^{1*3}+z^{4*3}\\[/tex] This can be simplified to, [tex]x^{15}y^{3}z^{12}\\[/tex].
Now divide the numerator by the denominator subtracting the exponents.
Which equals, [tex]x^{12}y^{2}z^{11}[/tex]
So a = 12
b = 2
and
c = 11
The values of [tex]a, \ b,\ c[/tex] are [tex]12,\ 2,\ 11[/tex] .
What are exponent ?Exponent indicates that the base is to be raised to a certain power. So, it is the power of the base.
We have,
[tex]\frac{(x^5yz^4)^3}{x^3yz}=x^ay^bz^c[/tex]
Now simplify the above given equation;
[tex]\frac{(x^5*3y^1*3z^4*3)}{x^3yz}=x^ay^bz^c[/tex]
[tex]\frac{(x^{15}y^3z^{12})}{x^3yz}=x^ay^bz^c[/tex]
Now, Using the exponent rule;
[tex]\frac{a^n}{a^m} = a^{n-m}[/tex]
So,
[tex](x^{15-3}y^{3-1}z^{12-1})=x^ay^bz^c[/tex]
[tex](x^{12}y^{2}z^{11})=x^ay^bz^c[/tex]
Now,
As we see variables on both sides of equation are same (i.e. bases of powers are same), so now compare the powers of sides of variables;
⇒ [tex]x^{12}=x^a[/tex]
[tex]a=12[/tex],
And, [tex]y^2=y^b[/tex]
[tex]b=2[/tex]
And, [tex]z^{11}=z^c[/tex]
[tex]c=11[/tex]
So, the values of [tex]a, \ b,\ c[/tex] are [tex]12,\ 2,\ 11[/tex] which are find out using the exponent rule.
Hence, we can say that the values of [tex]a, \ b,\ c[/tex] are [tex]12,\ 2,\ 11[/tex] .

Consider this right triangle with the given measures.
Answer:

Step-by-step explanation:
We were already given the formula and were left with [tex]169 = c^2[/tex].
To find c we would find what by itself equals 169.
We know [tex]12 * 12[/tex] is 144
so its greater than 12
we also know that 13 * 13 is 169
so c would be equal to 169
