y=x−1
2x+y=8
If you were to solve the following system using substitution, your new equation would be...
Answer:
2x+ (x-1) = 8
Simplified
3x-1 =8
Step-by-step explanation:
y=x−1
2x+y=8
Take the first equation and everywhere you see y in the second equation substitute x-1
2x+ (x-1) = 8
You can simplify
2x+x-1 =8
3x-1 =8
If you want to solve
3x-1+1 =8+1
3x= 9
Divide by 3
3x/3 =9/3
x=1
Then solve for y
y = x-1
y = 3-1
y=2

The distance between the amusement park and the bus terminal on a map is 2.25 inches. The map uses a scale in which 1 inch represents 15 miles. What is the actual distance between the amusement park and the bus terminal?
Answer:
33.75 miles
Step-by-step explanation:
[tex]\frac{1}{15} :\frac{2.25}{y}[/tex]
1 × y = 2.25 × 15
y = 33.75

What's the right answer?
Given:
[tex]sinh(f(x))=1+x^2[/tex]
To find:
The value of f'(x).
Solution:
Formulae used:
[tex]\dfrac{d}{dx}sinh(x)=cosh(x)[/tex]
[tex]\dfrac{d}{dx}x^n=nx^{n-1}[/tex]
[tex]\dfrac{d}{dx}C=0[/tex]
Chain rule:
[tex]\dfrac{d}{dx}[f(g(x))]=f'(g(x))g'(x)[/tex]
Where C is an arbitrary constant.
We have,
[tex]sinh(f(x))=1+x^2[/tex]
Differentiate with respect to x.
[tex]cosh(f(x))f'(x)=0+2x[/tex]
[tex]f'(x)=\dfrac{2x}{cosh(f(x))}[/tex]
Therefore, the required values is [tex]f'(x)=\dfrac{2x}{cosh(f(x))}[/tex].
According to the preamble, who gives power to the
Constitution?
O foreign powers
O the people
O the states

Answer:
A. [tex]\frac{9}{5}[/tex]
Step-by-step explanation:
-[tex]\frac{1}{4}[/tex] ( -[tex]\frac{4}{5}[/tex] / [tex]\frac{2}{3}[/tex] ) 6
Note that when dividing fractions, you can flip one and multiply instead to gte the same answer.
-[tex]\frac{1}{4}[/tex]*6( -[tex]\frac{4}{5}[/tex] * [tex]\frac{3}{2}[/tex] )
[tex]\frac{-6}{4}[/tex] ( [tex]\frac{-4*3}{5*2}[/tex] )
[tex]\frac{-6}{4}[/tex] ( [tex]\frac{-12}{10}[/tex] )
[tex]\frac{-6*-12}{4*10}[/tex]
[tex]\frac{72}{40}[/tex]
Divide top and bottom by 8.

NO LINKS!!! Find the measurement indicated. Round your answer to the nearest tenth.
Answer:
Solutions given;
Using cosine rule
b²=a²+c²-2*a*c*cos B°
b²=15²+8²-2*15*8*cos39
b²=102.48
b=[tex] \sqrt{102.48} [/tex]
b=10.12
b=10.1
Using sine rule
[tex] \frac{sin A}{BC} = \frac{sin B}{AC} =\frac{sin C}{AB} [/tex]
[tex] \frac{sin 29°}{15} =\frac{sin C}{8} [/tex]
Doing criss cross multiplication
Sin C=[tex] \frac{sin 29°}{15} ×8[/tex]
m<C=Sin -¹(0.29)
m<C=14.98
m<C=15°is a required answer.

x=-22
ONE HUNDRED POINTS PLEASE BE HONEST.
Answer:
12.207
Step-by-step explanation:
a^2 + b^2 = c^2
a and b are legs of the right triangle, c is the hypotenuse.
The hypotenuse squared is equal to the square root of (7^2 + 10^2).
The square root of 149 is around 12.207.
You cannot simplify the square root of 149 so if the question wants it in radical form just input square root of 149.

Answer:65454545
Step-by-step explanation:
A Sociology student investigated the association between a country's Literacy Rate and Life Expectancy, and then drew the conclusions listed below. Explain why each statement is incorrect. (Assume that all the calculations were done properly.)
a) The $$R^2$$ of 64% means that the Literacy Rate determines 64% of the Life Expectancy for a country.
b) The slope of the line shows that an increase of 5% in Literacy Rate will produce a 2-year improvement in Life Expectancy.
Solution :
The term 'literacy rate' provides the ability of a person who is from a definite age group can read or write.
a). [tex]$R^2$[/tex] does not determine the rate at which the variable explains another, but it explains the amount the amount of variability in one of the variables as explained by the other variable.
b). The slope given provides an expected improvement but it cannot guarantee the improvement. The value may be less or it could be more also.
The regression model provides the prediction and not the actual values.
