Answer:
x=0 , x=-3
Step-by-step explanation:
Apply all exponent rules:
[tex]3^{x+3}[/tex] = [tex]3^{x}[/tex]×[tex]3^{3}[/tex]
[tex]\frac{1}{3^{x} }[/tex] = [tex](3^{x} )^{-1}[/tex]
Rewrite equation with [tex]3^{x}= u[/tex]
[tex]u[/tex] × [tex]3^{3}[/tex] + [tex]u^{-1}[/tex] - 28 = 0
Solve for u to give :
u = 1, u = 1/27
Substitute back u = [tex]3^{x}[/tex], solve for x :
[tex]3^{x}[/tex] = 1 , x= 0
[tex]3^{x}= \frac{1}{27}[/tex] , x= -3
x=0 , x=-3
Substituting x back into original equation verifies our answers
Quentin agreed to pay 7% shipping and handling charge. If Quentin paid $9. 45 in shipping and handling, how much must the racquet have cost?
Answer:
The cost of the racquet is $135
Step-by-step explanation:
Let
x-----> the cost of the racquet
we know that
The racquet represent the 100%
so
using proportion
x/100%= $9.45/7%
x=100%*($9.45)/7

What fraction of the sweaters cost $50 or less?
Answer:
8/15 is the fraction I think
The answer is that 50% of the sweaters cost $50 or less.
What is a box plot?To determine the fraction of sweaters that cost $50 or less, we need to look at the box plot and identify the range of prices that fall within that category.
Looking at the box plot, we can see that the box extends from $40 to $60, which means that 50% of the sweaters sold were priced between $40 and $60. Additionally, we can see that the left whisker of the box plot extends down to $30, which means that some sweaters were sold for less than $40.
Therefore, to find the fraction of sweaters that cost $50 or less, we need to calculate the portion of the box plot that falls below $50.
From the box plot, we can see that the distance between $40 and $50 is half of the total distance of the box or 25%. And the distance between $30 and $40 is also 25%. Therefore, the total fraction of sweaters that cost $50 or less is 25% + 25% = 50%.
So, the answer is that 50% of the sweaters cost $50 or less.

Select all of the sets of measurements that can form a triangle.
35°, 15, 130°
90°, 3 inches, 7 inches
70°, 70°, 70°
17 inches, 8 inches, 2 inches
5 inches, 6 inches, 7 inches
The sets of measurements that can form a triangle are:
90°, 3 inches, 7 inches
5 inches, 6 inches, 7 inches.
To determine which sets of measurements can form a triangle, we need to apply the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Let's analyze each set of measurements:
35°, 15, 130°:
This set cannot form a triangle because the angles are not appropriate. The sum of the angles in a triangle must be 180°, but the given angles add up to 180° - (35° + 130°) = 15°, which is not possible.
90°, 3 inches, 7 inches:
This set can form a triangle. The sum of the two shorter sides (3 inches + 7 inches) is greater than the longest side (10 inches), satisfying the triangle inequality theorem.
70°, 70°, 70°:
This set cannot form a triangle because the angles are not appropriate. The sum of the angles in a triangle must be 180°, but the given angles add up to 210°, which is greater than 180°.
17 inches, 8 inches, 2 inches:
This set cannot form a triangle. The sum of the two shorter sides (2 inches + 8 inches) is less than the longest side (17 inches), violating the triangle inequality theorem.
5 inches, 6 inches, 7 inches:
This set can form a triangle. The sum of the two shorter sides (5 inches + 6 inches) is greater than the longest side (7 inches), satisfying the triangle inequality theorem.
Therefore, the sets of measurements that can form a triangle are:
90°, 3 inches, 7 inches
5 inches, 6 inches, 7 inches.

The spinner is equally likely to land on any of the six sections. a spinner contains 6 equal sections: 1, 2, 3, 4, 5, 6. sections 1, 3, and 5 are shaded. the spinner is pointing at number 6. what is the probability that the spinner will land on a number greater than 4 or on a shaded section? two-ninths one-half two-thirds five-sixths
The probability that the spinner will land on a number greater than 4 or on a shaded section is five-sixt
What is probability?Probability is the likelihood or chance that an event will occur. Mathematically;
Probability = Expected/Total
If the spinner is spinned, the total outcome is 1/6
Pr(greater than 4) = 2/6 = 1/3
Pr(shaded section) = 3/6 = 1/2
Pr(number greater than 4 or on a shaded section) = 1/3 + 1/2
Pr(number greater than 4 or on a shaded section) = 5/6
Hence the probability that the spinner will land on a number greater than 4 or on a shaded section is five-sixths

Stephen bought a package of stickers for $0.50. His brother bought 4 times as many packages. How much did his brother spend? (3 points) a $2.00 b $2.25 c $2.50 d $3.00
a $2.00
Step-by-step explanation:
0.50 x 4 = 2
If he bought 4 times as many, then take the price times 4.
Answer:
$2.00
Step-by-step explanation:
Stephen bought 1 package for $0.50. His brother bought 4 times as many (4 * 1 packages). Which means his brother bought 4 packages.
If each package costs $0.50 then we simply multiply the price with the amount of packages he bought:
4 * $0.50. Lets get rid of the dollar sign, so it doesn't distract us.
I'm not sure if you studied about floating point numbers yet, but I assume you did.
4 * 0.50 =?
We have two numbers after the floating point, but for the sake of simplicity we can get rid of it too and just multiply 4 * 50 and then put the floating point back into the number after the first two digits (because we removed it after two digits 0.50)
Anyway 4 * 50 = 200
We add the floating point and get:
2.00
Therefore his brother spent $2.00 after we add the dollar sign back in

every child has a 1 mom
f 7 = 3 f7= -6 this is imposible

Explanation:
If the first values of the two ordered pairs are the same, the relation is not a function.
Solve:
2k + 1 = 3k -2
2k - 3k = -2-1
-k = -3
k = 3
When k = 3, for the relation R= {(2k+1, 3), (3k-2, -6)} will not be a function.
