Answer:
Step-by-step explanation:
first step: 0.5 * x
second step: 3* (0.5x) = 1.5x
third step: (1.5x)^2
fourth step: (1.5x)^2 + 1 = 50
(1.5x)^2 + 1 = 50 Subtract 1 from both sides
(1.5x)^2 = 49 Take the square root of both sides
1.5x = sqrt(49)
1.5x = +/- 7
1.5x = +7
x = 7/1.5
x = 4.67
1.5x = - 7
x = - 7 / 1.5
x = - 4.67
In the past, 30% of a country club's members brought guests to play golf sometime during the year. Last year, the club initiated a new program designed to encourage members to bring more guests to play golf. In a sample of 95 members, 34 brought guests to play golf after the program was initiated. When testing the hypothesis that the new program has increased the proportion of members bringing out guests (using a 5% level of significance), what is the null and alternative hypothesis
Answer:
The null hypothesis, H₀: p = 0.3
The alternative hypothesis is Hₐ: p ≠ 0.3
Step-by-step explanation:
The null hypothesis, H₀, in inferential statistics is the default hypothesis that the measured quantity is zero or null and therefore there is no difference between the population characteristic measured, when the quantity measured is the difference between two situations
Therefore, the null hypothesis, H₀: p = 0.3
The alternative hypothesis is usually the opposite of the null hypothesis, therefore, the alternative hypothesis Hₐ is given as follows;
The alternative hypothesis is Hₐ: p ≠ 0.3

Write an equivalent expression for each operation.
(3 + 2i) + (4 + 5i)
Help me plz ASAP
Answer:
The equivalent expression is [tex]7(1+i)[/tex]
Step-by-step explanation:
Additional of complex numbers:
When we add complex numbers, we add both it's real parts and imaginary parts.
In this question:
[tex](3 + 2i) + (4 + 5i) = 3 + 4 + (2+5)i = 7 + 7i = 7(1+i)[/tex]
The equivalent expression is [tex]7(1+i)[/tex]
Use substitution to solve the following system of equations. 4x – 13y = -12 AND X = 2y - 8
Answer:
y=5/4=0.8
Step-by-step explanation:
(4×2y−8)−13y=−12
Multiply 4 and 2 to get 8.
8y−8−13y=−12
Combine 8y and −13y to get −5y.
−5y−8=−12
Add 8 to both sides.
−5y=−12+8
Add −12 and 8 to get −4.
−5y=−4
Divide both sides by −5.
y=−5−4
Fraction −5/−4 can be simplified to 5/4 by removing the negative sign from both the numerator and the denominator.
y=5/4

- 10x + y = 4
Please help I’ve been stuck on this for an hour now PLEASEEEEE
Answer:
y= 10x + 4
Step-by-step explanation:
-10x + y = 4
-10x + y +10x = 10x + 4
y= 10x + 4
depending on what its asking usually this is what its asking for but im not sure exaclty what its asking so here.....
next step is to plug the numbers in
so for the first box it says that x is -2
plug it in.....
y = 10(-2) + 4
y = -20 + 4
y = -16
then keep doing it for the next boxes.....
second box:
y = 10(-1) + 4
y = -10 + 4
y = -6
third box:
y = 10(0) + 4
y= 4 because 10 times zero is zero (basically any number times 0 is zero)
fourth box:
y = 10(1) + 4
y = 10 + 4
y = 14
fifth box:
y = 10(2) + 4
y = 20 + 4
y = 24
Hope this helps!

2|2x-6|=20
How the hell do you do this guys :(
Answer:
x1 = -2, x2 = 8
Step-by-step explanation:
You can first divide both sides of the equation by 2 so now you have:
I 2x - 6 I = 10
Then use the absolute value definiton and rewrite it into two separate equations:
1.) 2x - 6 = -10
2.) 2x - 6 = 10
From here you can solve both equations:
1.) x = -2
2.) x = 8

Find the equation of the line with slope m=1 that contains the point (1,2)
Answer:
y = x + 1
Step-by-step explanation:
We can use the point-slope formula to write an equation for this problem. The point-slope formula states: (y - y1) = m (x - x1)
Where m is the slope and (x1 y1) is a point the line passes through.
Substituting the slope and the values from the point in the problem gives:
( y - 2 ) = 1 ( x - 1 )
We can also solve for y to put the equation in slope-intercept form. The slope-intercept form of a linear equation is: y = mx + b
y - 2 = 1x - 1
y = 1x - 1 + 2
y = 1x + 1 or y = x + 1 * are just the same.
The equation of the line is y = x + 1.
What is a slope?The slope and direction of a line are represented numerically by the line's gradient, which is also referred to as the slope in mathematics.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
And here we have the slope,
m = 1
And (x₁ ,y₁) = (1,2)
then the equation of line is
y - y₁ = m (x - x₁)
y - 2 = (x -1)
y = x + 1
Therefore, the equation is y = x + 1.

Find the value of the expression a? – b2 for a = 2 and b=1
Answer:[tex]a^2-b^2=3[/tex]
Step-by-step explanation:
We need to find the value of the below expression i.e.
[tex]a^2-b^2[/tex] when a = 2 and b = 1.
So,
Put a = 2 and b = 1 in the above expression. So,
[tex]a^2-b^2=(2)^2-1^2\\\\=4-1\\\\=3[/tex]
Hence, the value of the expression is equal to 3.
Please explain in words.
Answer:
Negative
Step-by-step explanation:
The following expression will be negative. This is because, the fraction in x is a negative fraction. The fraction in y is a positive fraction. The expression is x * y, so if you were to multiply the two it would be negative. This is because a negative multiplied by a positive will be equal to a negative.
