The expression -8 less than a number is no more than 12 will be given as x - 8 ≤ 12

Let the unknown values be "x"

a) The sum of a number and 12 is expressed as x + 12

If the result is at most -8, the required inequality will be x + 12 ≤ 8

c) If a number is increased by -8, the result will be x - 8. the expression -8 is greater than 12 will be given as x - 8 > 12 greater than 12.

b) If a number is increased by -8, the result will be x - 8. The expression -8 less than a number is no more than 12 will be given as x - 8 ≤ 12

Answer:

So the answer is that 5 3/10 as a decimal is 5.3. 9/10 as a decimal is expressed as 0.9.

Step-by-step explanation:

To convert any fraction to its decimal form, we just need to divide the numerator by the denominator.

In this case, we divide 9 by 10, 9 ÷ 10 = 0.9

It's not B or C because the ball goes up after reaching the roof but should fall down.

Answer: it's 31.3 percent.

Step-by-step explanation:

55 feet of 80 is 68 percent, to find the remainder you need to subtract 68 by 100, and with that, you get 31.3 percent.

if you want that in feet it's about 25 feet

Answer:

1,183.5

Step-by-step explanation:

When dividing 2,367 by 2, the quotient is 1,183 with a remainder of 1 by performing long division by starting with the leftmost digit of the dividend.

To divide a number by another number and find the quotient and remainder, follow these steps:

Step 1: Divide the first number (dividend) by the second number (divisor). In this case, divide 2,367 by 2.

Step 2: Perform long division by starting with the leftmost digit of the dividend. Divide the digit by the divisor and write the quotient above the division bar.

Step 3: Multiply the quotient by the divisor and subtract the result from the current partial dividend.

Step 4: Bring down the next digit of the dividend and continue the division process until all digits have been used.

Step 5: The final quotient is the whole number obtained from the division, and the remainder is the remaining digit.

In the case of 2,367 divided by 2, the long division process would yield a quotient of 1,183 and a remainder of 1.

Therefore, 2,367 divided by 2 gives a quotient of 1,183 with a remainder of 1.

The equation which shows the true solution to the given logarithmic equation is,

[tex]x=1[/tex]

The power of the log rule says that the number written in the front of the logarithmic function can be raised to the power of the logarithmic function.

For example,

[tex]n\log_b(M)=\log_b(M)^n[/tex]

Given information-

The logarithmic equation given in the problem is,

[tex]3\log_2(2x)=3[/tex]

Using the power rule of the logarithmic function,

[tex]\log_2(2x)^3=3[/tex]

Using the exponent rule of the logarithmic function the above equation can be written as,

(1, 5) A rotation of 90° counterclockwise around the origin can be described in mathematical terms as (x, y) → (−y, x).

(1, 5) → (-5, 1), or C

Answer:

B. (-5, -1)

Step-by-step explanation:

Since we're solving for A :

A (-4, 3) translated 3 units to the right and 2 units up would be A (-4 + 3, 3 + 2), which is A' (-1, 5). Then, we have to rotate it 90 degrees clockwise. This would be (-5, -1), as the formula states (x, y) -> (-y, x), which means the x stays the same but goes to the 'y' position, and the y sign changes and goes to the 'x' position.

So, it would be (-5, -1) :)

Answer:

Step-by-step explanation:

The exact value for the expression √52 – √13 + √117 given in the question above is 4√13

a√b + c√b = (a + c)√b

With the above information in mind, we can simplify the express given in the question above.

√52 – √13 + √117

Recall

√52 = √(4 × 13) = 2√13

√117 = √(9 × 13) = 3√13

Thus

√52 – √13 + √117 = 2√13 – √13 + 3√13

√52 – √13 + √117 = (2 – 1 + 3)√13

√52 – √13 + √117 = 4√13

Answer:

slope: 2 as we see, with every increase in x, y increase twice the more.

Step-by-step explanation:

The slope of the linear graph in the question obtained using the ratio of the rise and run of the line is 2.

Recall :

Slope = Rise / Run

From the graph :

Rise = y2 - y1 = 5 - (-1) = 5 + 1 = 6

Run = x2 - x1 = 2 - (-1) = 2 + 1 = 3

The slope of the graph can be expressed thus :

Slope = Rise / Run = 6 /3 = 2

Therefore, the slope of the line in the graph attached is 2
