Please solve for x.
4^3x+1 = 4^5


Answers

Answer: x= 1023 /64

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

64x+1=1024

Step 2: Subtract 1 from both sides.

64x+1−1=1024−1

64x=1023

Step 3: Divide both sides by 64.

64x /64 = 1023 /64

x= 1023 /64

Answer:

1023/64

Step-by-step explanation:

4^3x+1=4^5

64x+1=4^5

64x+1-1=1024-1

64x=1023

64x/64}=1023/64

How do I solve 3(x−9)=30

Answers

Answer:

x = 19

Step-by-step explanation:

use the distributive property

3(x - 9) = 30

3x - 27 = 30

     +27   +27

3x = 57

divide by 3

x = 19

Hope this helped! Have a nice day! Plz mark as brainliest!!! :D

-XxDeathshotxX

Answer:

The value of x is 19.

Step-by-step explanation:

The steps are :

3(x- 9) = 30

3(x - 9) ÷ 3 = 30 ÷ 3 [eliminate 3 on left side]

x - 9 = 10

x - 9 + 9 = 10 + 9 [eliminate -9 on left side]

x = 19

1) Simplify the following:

9r + 8 - 4r - 6

2) Simplify the following:

2(x + 3y)

(I know you can’t add some of them because of their variables, but I want the simplified version)

Answers

Step-by-step explanation:

ok so for number 1 you first have to group the like terms therefore you will now have:

9r-4r+8-6

and now you calculate:

9r-4r=5r

8-6=2

so that means 5r-2 is simplied version for no.1

for number you 2 you first multiply why is inside the brackets by what is in the outside:

2(x+3y)

2x+6y (simplified version)

hope this helps! no problem

Given that sin 60° ≈ 0.866, write the
cosine of a complementary angle

Answers

Answer:

Step-by-step explanation:

Complement to 60° = 30°

cos(30°) = sin(60°) = 0.866

Answer:

0.866.

Step-by-step explanation:

We use the identity

sin x = cos (90-x)

So the cosine of the complementary angle is also 0.866.

Square FGNM and its diagonals are shown below. Which pairs of line segments are parallel? Select all that apply.

Answers

Answer:

The parallel sides are:

Step-by-step explanation:

The question is incomplete, as the image of the square is not attached.

However, I will answer this question using a general rule.

When a square is named ABCD, it means that AB and DC are parallel sides & BC and AD are also parallel

Using this logic, the parallel sides of FGNM are:

- FG and MN

- GN and FM

The diagonals are:

FN and GM

Determine the center and radius of the following circle equation: x² + y2 + 2x – 2y – 62 = 0​

Answers

Step-by-step explanation:

x²+2x+y²-2y=62

using completing the square

x²+2x+1+y²-2y+1=62+1+1

(x+1)²+(y-1)²=64

(x+1)²+(y-1)²=8²

(x-a)²+(y-b)²=r²

by comparison

(a,b)=(-1,1)

a,b is the center of the circle

r=8unit

r is the radius

The scale factor of the scale drawing of a mirror to the actual mirror is represented by the ratio 1 : 8 . If the dimensions of the scale drawing are 3 inches wide by 8.5 inches long, what is the actual area of the mirror?

Answers

Answer: 204 square inches

Step-by-step explanation: I’m not really sure, but if you follow through with the normal area identifying method; Length x Width, you should come up with 25.5. After doing this, you could multiply your product by 8 because your actual mirror size is 8 times greater. You will come up with 204 square inches, which would be your final solution. (Once again, I am not sure, just doing how I’ve been understanding from studies).

Which set of measurements could not represent the side lengths of a right triangle?
A 16 ft, 30 ft, 34 ft
B 9 ft, 12 ft, 15 ft
C 7ft, 24 ft, 25 Ft
D 5ft. 7 ft, 12 ft

Answers

The answer is C
Step by step explanation
16 ft,30 ft 34ft

The set of measurements could not represent the side lengths of a right triangle is 5ft. 7 ft, 12 ft.

What is a right triangle?

The right is a triangle with has one angle 90° and square of hypotenuse is equal to the sum of square of other two legs.

Given that, the set of measurements representing the side lengths of a right triangle,

We will check the measurements by seeing if they are following the Pythagoras theorem or not,

Option A)

16 ft, 30 ft, 34

16²+30² = 1156 = 34²

∴ 16²+30² = 34²

Option B)

9²+12² = 225 = 15²

9²+12² = 15²

Option C)

7²+24² = 625 = 25²

7²+24² = 25²

Option D)

5²+7² = 74 ≠ 12²

Since, 5ft. 7 ft, 12 ft set of  measurements are not following the Pythagoras theorem.

Therefore, it's not a right triangle.

Hence, The set of measurements could not represent the side lengths of a right triangle is 5ft. 7 ft, 12 ft.

14. A veterinarian tells Max that his cat
should lose no more than 30 ounces. The
veterinarian suggests that the cat should
0 to
lose 7 ounces or less per week. What is the
shortest time in weeks and days it would
take Max's cat to lose the 30 ounces?

Answers

Answer:

4 weeks 2 days

Answer:

4 weeks 2 days

Step-by-step explanation:

First do 30 divided by 7 to get the number of weeks.

Which is 4 weeks with a remainder of 2.

7 ounces per week is 1 ounce per day.

So to get 2 more ounces that would be 2 days.

Therefore the answer is 4 weeks and 2 days.
