solve for x: 7^(3x+7)=7^(-8x-4)
Answer:
x = -1
Step-by-step explanation:
7^(3x+7) = 7^(-8x-4)
First Step: Cancel out like bases.
3x + 7 = -8x - 4
Second Step: Add 8x on both sides.
11x + 7 = -4
Third Step: Subtract 7 on both sides.
11x = -11
Fourth Step: Divide by 11 on both sides.
x = -1
(8x/2)^3 whats the answer??????
Answer:
(8x)^(2/3
Step-by-step explanation:
4x - 7 (2 - x) = 3x + 2
Answer:
x=2
Step-by-step explanation:
4x−7(2−x)=3x+2
4x+(−7)(2)+(−7)(−x)=3x+2(Distribute)
4x+−14+7x=3x+2
(4x+7x)+(−14)=3x+2(Combine Like Terms)
11x+−14=3x+2
11x−14=3x+2
Step 2: Subtract 3x from both sides.
11x−14−3x=3x+2−3x
8x−14=2
Step 3: Add 14 to both sides.
8x−14+14=2+14
8x=16
Step 4: Divide both sides by 8.
x=2

If all else remains constant and the values of two variables move in the same direction it indicates a Group of answer choices negative slope relationship. inverse slope relationship. the values of the two variables will move in the same direction then move in opposite directions. positive slope relationship.
Answer:
positive slope relationship.
Step-by-step explanation:
When two variables move in the same direction, they are positively related. An increase in one variable would lead to an increase in the other variable.
For example, price and quantity supplied are positively correlated. An increase in price, leads to an increase in quantity supplied and a decrease in price leads to a decrease in quantity supplied.
Please check the attached image for a positively correlated curve

The probability that Chloe is happy given that she has had dinner by 6pm is 0.9. The probability that Chloe is not happy given that she has not had dinner by 6pm is 0.8. Assume that there is a 60% chance that Chloe eats dinner by 6pm on a given day. a) If Chloe is not happy at 6pm, find the probability that she has not had dinner yet. b) If Chloe is happy at 6pm, find the probability that she has already had dinner.
Answer:
a) If Chloe is not happy at 6pm, the probability that she has not had dinner yet =P(B/D)= 0.8
b) If Chloe is happy at 6pm,the probability that she has already had dinner= P(A/C) = 0.9
Step-by-step explanation:
Let A be an event that Chloe is happy given that she has had dinner by 6pm
P(A) = 0.9
Let B be an event that Chloe is not happy given that she has not had dinner by 6pm
P(B) = 0.8.
Let C be an event that Chloe eats dinner by 6pm on a given day
P(C) = 60%=0.6
Let D be an event that Chloe does not eat dinner by 6pm on a given day
P(D) = 1- 60%=1- 0.6= 0.4
This requires conditional probability .
Part a
P(B/D)=P(B∩D)/P(D)
P(B∩D) = 0.8 *0.4=0.32
P(D) = 0.4
P(B/D)=P(B∩D)/P(D)
= 0.32/0.4= 0.8
P(B)= P(B/D)
0.8 is equal to 0.8
This shows that the events are independent.
b)
P(A/C)= P(A∩C)/ P (C) = 0.9*0.6/0.6= 0.9
Which is again equal to probability of event A showing that the events are independent.

Find the slope of the line passing through each of the following pairs of points and draw the graph of the line.
(6, −7), (6, 1)
Answer: undefined; vertical line
Step-by-step explanation:
To find the slope, you use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]m=\frac{1-(-7)}{6-6} =\frac{8}{0}[/tex]
The slope is undefined because you cannot divide anything by 0.
The graph of the line is a vertical line at x=6. We know this because the points are both at x=6, with different y-values.

Find the unknown length y in the pair of similar triangles.
Step-by-step explanation:
If 2 triangles are similar then the ratio of any 2 sides of one triangles will be equal to the ratio of any 2 sides of the another triangle.
So,

A class has 6 boys and 14 girls. What is the ratio in simplest form?
Answer: If your doing the ratio of boys to girls, it would be 6:14. Simplified- 3:7
Step-by-step explanation:
The factors of 6-1,2,3,6
The factors of 14-1,2,12,14
The common factor of the two #’s is 2 so you would divide both of them by that number. 3 and 7 are prime numbers so you can’t simplify the ratio anymore.

Hey there! I'm happy to help!
If we have g(-3) we plug -3 into our function as x.
-3-2(-3)²

Today only, a table is being sold at a 26% discount. The sale price is $481.
What was the price yesterday?
Answer:
The price yesterday was 650
Step-by-step explanation:
X is the price yesterday
There is a 26% discount
That means today we pay 100 -26 = 74 %
x* 74% = 481
.74x = 481
Divide each side by .74
.74x/.74 = 481/.74
x = 650
The price yesterday was 650

Find the measures of angles 1 through 5 in the figure shown.
Its 4 PARTS
The measure of angle ∠1 is 44 degrees and the measure of angle ∠5 is 62 degrees.
What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
Angle ∠1 and 46° are complementary angles. Then we have
∠1 + 46° = 90°
∠1 = 44°
Angle ∠1 and ∠3 are vertically opposite angles. Then we have
∠1 = ∠3 = 44°
The sum of all the angles of the triangle is 180 degrees. Then we have
∠3 + 74° + ∠5 = 180°
44° + 74° + ∠5 = 180°
∠5 = 62°
