Answer:
2.2%
Step-by-step explanation:
Use the percent error formula:
% error = | (approx - exact) ÷ approx | x 100
Plug in the approx. and exact values:
| (8.9 - 8.7) ÷ 8.9 | x 100
| (0.2) ÷ 8.9 | x 100
= 2.2
So, the percent error is 2.2%

Answer:
x=15 and y=49
Step-by-step explanation:
y+16=5x-10
and (y+16) + (8x-5)=180
so y=5x-26 and then
plug in for y so 5x-26+16+8x-5=180
that means x=15
plug in for x
y+16= 5(15)-10
that means y=49

b = 7 as per the first pointAnd the slope is:
m = (-2 - 7)/(8 - 0) = -9/8So the line is:

plz help me
Answer:
slope (m)= 1/2
y-intercept: (0, -1)
equation: y=[tex]\frac{1}{2}[/tex]x-1
Step-by-step explanation:
slope is [tex]\frac{rise}{run\\}[/tex]=[tex]\frac{1}{2}[/tex]
y-intercept is where the line crosses the vertical axis (y-axis) so its (0, -1)
using point slope form:
y-y1=m(x-x1)
y-(-1)=1/2(x-0)
y+1=1/2x
y=[tex]\frac{1}{2}[/tex]x-1

Step-by-step explanation:
To simplify the expression [tex]4^{4}\times4^{3}[/tex], we can use the first law of the law of indices which states that the exponent is added together when multiplying numbers with the same base. Eg: [tex]a^{x}\times a^{y} = a^{x+y}[/tex].
[tex]4^4 \times4^3=4^{4+3}[/tex]

Is f(x)=3x5^2x-3 an exponential function? If so, write it in the form f(x)=ab^x
Answer:
[tex]f(x)=\frac{3}{125} * 25^x[/tex]
Step-by-step explanation:
Given
[tex]f(x)=3*5^{2x-3}[/tex]
Required
To determine if it is an exponential function, we have to write in form of
[tex]f(x) = ab^x[/tex]
If we're able to do so, then the function is an exponential function.
If otherwise, then it is not
[tex]f(x)=3*5^{2x-3}[/tex]
Apply Law of indices
[tex]f(x)=3*\frac{5^{2x}}{5^3}[/tex]
Express 5^3 as 125
[tex]f(x)=3*\frac{5^{2x}}{125}[/tex]
Factorize the exponent of 5
[tex]f(x)=3*\frac{5^{(2)x}}{125}[/tex]
Express 5^2 as 25
[tex]f(x)=3*\frac{25^x}{125}[/tex]
This can be rewritten as:
[tex]f(x)=\frac{3}{125} * 25^x[/tex]
By comparing the above to [tex]f(x) = ab^x[/tex]
We have that
[tex]a = \frac{3}{125}[/tex]
[tex]b^x = 25^x[/tex]
Since, we've be able to express the function as [tex]f(x) = ab^x[/tex]
Then, [tex]f(x)=3*5^{2x-3}[/tex] is an exponential function
The expression in exponential form is expressed as [tex]g(x)=\frac{3}{125} \cdot 25^x[/tex]. Option C is correct.
Given the equation [tex]f(x) = 3\cdot 5^{2x-3}[/tex], we are to write in the form [tex]a(b)^x[/tex]
Simplifying the given expression, we will have:
[tex]g(x) = 3\cdot 5^{2x-3}\\g(x) = 3\cdot 5^{2x} \cdot 5^{-3}\\g(x) =\frac{3}{5^3}\cdot (5^2)^x\\g(x)=\frac{3}{125} \cdot 25^x[/tex]
Hence the expression in exponential form is expressed as [tex]g(x)=\frac{3}{125} \cdot 25^x[/tex]

Linda Is working at an art shop. She will be paid a daily amount plus a commission of a total sales. The equation y = .10x + 85 represents the amount Linda will make
Answer:
Income Linda make = $150
Step-by-step explanation:
Given:
y = 0.10x + 85
Assume;
Sales = $650
Find:
Income Linda make
Computation:
Income Linda make = 0.10x + 85
Income Linda make = 0.10(650) + 85
Income Linda make = 65 + 85
Income Linda make = $150

Tony and Sam are sharing the driving on a 520-mile trip. If Tony drives 90 more miles than Sam, how far did each of them drive?
Answer:
miles driven by sam =215 miles
Miles driven by Tony = 305 miles.
Step-by-step explanation:
Let the miles driven by sam is x
given that Tony drove 90 miles more than sam
miles driven by Tony = miles driven by sam + 90 = x + 90
Total miles driven by them together
= miles driven by Tony + miles driven by sam = x + 90 + x = 2x + 90
given
Tony and Sam are sharing the driving on a 520-mile trip
2x + 90 = 520
2x = 520 - 90 = 430
x = 430/2 = 215
Thus,
miles driven by sam = x = 215 miles
Miles driven by Tony = x + 90 = 215 + 90 = 305 miles.
