The solution to 5(x-2)-6=24 is which of the following? Show the steps in your solution process.
Answer:
x=8
Step-by-step explanation:
distributive property
5x-10-6=24
adding -10 and -6 which is -16
5x-16=24
add 16 on both sides to cancel the -16
5x=40
than divide 5 to cancel out the 5
x=8
Hi, I was wondering why (-1)(-1)(-1)(-2) equals 2 but (-2)(-4)(-3) equals -24. Thank you in advance.
Answer:
-1*-1= 2;2*-1=-1;-1*-2=2
Step-by-step explanation:
negative times neg equals positive
Because when you add negatives together it goes more down because you are adding negatives together. if you add 2 negatives it decreases in value but when you subtract 2 negatives from each other the number increases.

Step-by-step explanation:
A political analyst believes that a senator's recent decision to support a bill resulted in a drop of approval ratings. To test this claim, he selects random cities in the state the senator represents and compares the approval ratings before the decision to the approval ratings after the decision. Suppose that data were collected for a random sample of 8 cities, where each difference is calculated by subtracting the percent approval rating before the decision from the percent approval rating after the decision. Assume that the ratings are normally distributed. Using a test statistic oft -3.935, the significance level Q=0.05, and the corresponding p-value less than 0.01, draw a conclusion for the appropriate hypothesis test, where the null hypothesis is H. : = 0 and the alternative hypothesis is H. : < 0.
a. Reject the null hypothesis.
b. Fail to reject the null hypothesis.
c. The conclusion of the hypothesis test is that there is sufficient evidence to suggest that there was a drop in approval ratings in cities after the decision to support the bill.
d. The conclusion of the hypothesis test is that there is insufficient evidence to suggest that there was a drop in approval ratings in cities after the decision to support the bill.
Complete Question
A political analyst believes that a senator's recent decision to support a bill resulted in a drop of approval ratings. To test this claim, he selects random cities in the state the senator represents and compares the approval ratings before the decision to the approval ratings after the decision. Suppose that data were collected for a random sample of 8 cities, where each difference is calculated by subtracting the percent approval rating before the decision from the percent approval rating after the decision. Assume that the ratings are normally distributed. Using a test statistic oft -3.935, the significance level Q=0.05, and the corresponding p-value less than 0.01, draw a conclusion for the appropriate hypothesis test, where the null hypothesis is [tex]H_o. : \mu_d= 0[/tex] and the alternative hypothesis is [tex]H. : \mu_d < 0[/tex]
a. Reject the null hypothesis.
b. Fail to reject the null hypothesis.
c. The conclusion of the hypothesis test is that there is sufficient evidence to suggest that there was a drop in approval ratings in cities after the decision to support the bill.
d. The conclusion of the hypothesis test is that there is insufficient evidence to suggest that there was a drop in approval ratings in cities after the decision to support the bill.
Answer:
The correct option is a and c
Step-by-step explanation:
From the question we are told that
The sample size is n = 8
The test statistics is t = -3.935
The level of significance is [tex]\alpha = 0.05[/tex]
The p-value is [tex]p-value = 0.01[/tex]
From the data given we see that the [tex]p-value < \alpha[/tex] hence
The decision rule is
Reject null hypothesis
The conclusion
There is sufficient evidence to suggest that there was a drop in approval ratings in cities after the decision to support the bill.

You'll have three copies of the red "-x" rectangles to represent -3x
Next, you'll need five copies of the blue squares with the label "1". This represents 5 since 1*5 = 5.
Lastly, you'll need one copy of the purple rectangle that has "y" on it.
All of this forms the expression -3x+5+y
All of these figures will be above the dashed line to be in the positive region.

3(4x-7)=27
how do i solve this ?
Answer:
x=4
Step-by-step explanation:
3(4x-7)=27
Divide each side by 3
3/3 (4x-7)=27/3
4x-7 = 9
Add 7 to each side
4x-7+7 = 9+7
4x = 16
Divide each side by 4
4x/4 = 16/4
x = 4

Line A is parallel to line b. If the measures of <2 is 78o, what is the measure of <5?
Answer:
∠7 = 102°
Step-by-step explanation:
∠2 ≅ ∠6 [Corresponding Angles]
So,
∠6 = 78°
Now,
∠6 + ∠7 = 180°
Where ∠6 = 78°
78° + ∠7 = 180°
∠7 = 180° - 78°
∠7 = 102°
Hope this helped!
~AnonymousHelper1807The sum of any number and its ______
equals 0.
Answer:
The sum of the real number (a) and its opposite real number (-a) is zero
Step-by-step explanation:
5 + (-5) = 0 and (-5) + 5 = 0
or, 5 - 5 = 0 and -5 + 5 = 0
Here 5 is real number and (-5) is it's opposite real number. Sum of 5 and (-5) is zero.
How to solve trigonometric functions such as
sin 2x sin x + cos x= 0
Use the double angle identity:
sin(2x) = 2 sin(x) cos(x)
Now rewrite
sin(2x) sin(x) + cos(x) = 0
as
2 sin²(x) cos(x) + cos(x) = 0
Factor out cos(x) :
cos(x) (2 sin²(x) + 1) = 0
Consider the two cases,
cos(x) = 0 OR 2 sin²(x) + 1 = 0
Solve for cos(x) and sin²(x) :
cos(x) = 0 OR sin²(x) = -1/2
Squaring a real number always gives a non-negative number, so the second case doesn't offer any real solutions. We're left with
cos(x) = 0
Cosine is zero for odd multiples of π/2, so we have
x = (2n + 1) π/2
where n is any integer.
is 4(x-8)=4x-8 One solution no solution or infinite solutions explain your answer
Answer:
No solution
Step-by-step explanation:
4(x-8) = 4x-8
Distribute.
4x-32 = 4x-8
Subtract 4x first and get rid of the variable (x).
4x-32 = 4x-8
-4x -4x
-32 = -8
-32 does not equal -8, so there is no solution!
