Answer:
x=14 to make the pay equal.
Step-by-step explanation:
Okay so what I did here is kind of time-consuming and I'm sure there's a better way, but I used a calculator to substitute a lot of different numbers into the equation to make it equal, and when I got to 14, the equations both ended up as 625.

Helpppppppp asap please with calculations pls pls pls
Answer:
For the first one it is y = -5x because for it to be direct it can't have a b-intercept. it must start at 0.
Second question: y2 - y1/x2 - x1
13-(-8)/(-4)-3
21/(-7)
-3 is the slope
y= -3x + b
13 = -3(-4) + b
13 = 12 + b
12 - 13 = b
b = -1
y=-3x-1
0 = -3x - 1
1 = -3x
1/-3 = -3x/-3
x= -1/3
y=-3x-1
y=-3(0)-1
y= -1
The answer to the 3rd question is y = 1x + 2 because the rise over run is one and the line crosses the y-intercept at 2.
I am not sure if these answers are correct.
In a survey of 2,700 people who owned a certain type of car, 1,755 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
65%
Step-by-step explanation:
survey of 2,700 people who owned a certain type of car, 1,755 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Total car number of car owner= 2,700
Then the percentage that satisfied is
1,755
1755/2700*100= 65%

1/2z+6=3/2(z+6) need the answer asap
Answer:
z = -3
Step-by-step explanation:
[tex]\frac{1}{2}[/tex]z+6 = [tex]\frac{3}{2}[/tex](z+6)
Expand and cancel out brackets.
[tex]\frac{1}{2}[/tex]z+6 = [tex]\frac{3}{2}[/tex]z +
Simplify.
[tex]\frac{1}{2}[/tex]z+6 = [tex]\frac{3}{2}[/tex]z + 9
Isolate x and numbers.
[tex]\frac{3}{2}[/tex]z - [tex]\frac{1}{2}[/tex]z = 6-9
Simplify.
[tex]\frac{2}{2}[/tex]z = -3
z = -3
Answer:
z=−3
Step-by-step explanation:
1/2*z+6-(3/2*(z+6))=0
Simplify 3/2
1 3
((— • z) + 6) - (— • (z + 6)) = 0
2 2
Simplify 1/2
Rewrite the whole as 6.1 Pull out like factors :
-2z - 6 = -2 • (z + 3) a fraction using 2 as the denominator.
-z - 3 = 0
7.1 Solve : -z-3 = 0
Add 3 to both sides of the equation :
-z = 3
Multiply both sides of the equation by (-1) : z = -3
Traci collects donations for a dance marathon. One group of sponsors will donate a total of $6 for each hour she dances. Another group of sponsors will donate $75 no matter how long she dances. What number of hours, to the nearest minute, should Traci dance if she wants to raise at least $1,000?
Answer:155 hours
Step-by-step explanation:
$75+$6h=$1,000
Subtract $75 on both sides:
$75-$75+$6h=$1,000
$6h=$925
Divide 6 on both sides:
6/6h=925/6
h=154.1666667
After I rounded it and it was 155 hours

Does 3x-2=2x-3have infinitely many solutions
Hi there! :)
[tex]\large\boxed{\text{One solution: x = -1}}[/tex]
3x - 2 = 2x - 3
Subtract 2x from both sides:
3x - 2x - 2 = 2x - 2x - 3
x - 2 = - 3
Add 2 to both sides:
x - 2 + 2 = -3 + 2
x = -1
Therefore, the equation only has ONE solution.
A research team is testing whether a fuel aditive increases a car's gas mileage. The maker of the additive claims that the additive will increase a car's gas mileage by at least 6 mpg. Among 25 cars that were treated with the additive, the average increase in mileage was 5.3 mpg with a standard deviation of 1.8 mpg. The research team found the z-score to be -1.94. Is there enough evidence to reject the company's evidence?
Answer:
Yes there is sufficient evidence to reject the company's evidence
Step-by-step explanation:
From the question we are told that
The sample size is n = 25
The mean is [tex]\= x = 5.3 \ mpg[/tex]
The standard deviation is [tex]\sigma = 1.8 \ mpg[/tex]
The z-score is z = -1.94
The null hypothesis is [tex]H_o : \mu = 6 \ mpg[/tex]
The alternative hypothesis is [tex]H_a : \mu \ne 6[/tex]
Generally the p-value is mathematically evaluated as
[tex]p-value = 2 * P( Z <-1.94)[/tex]
From the z table the area under the normal curve to the left corresponding to -1.94 is
[tex]P( Z <-1.94) = 0.02619[/tex]
=> [tex]p-value = 2 * 0.02619[/tex]
=> [tex]p-value = 0.052[/tex]
Let assume the level of significance is [tex]\alpha = 0.05[/tex]
Hence the [tex]p-value > \alpha[/tex] this mean that
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is sufficient evidence to reject the company's evidence
