Answer:

y = - [tex]\frac{12}{5}[/tex]

Step-by-step explanation:

Given

3x - 5y = 15 ← substitute x = 1 into the equation

3(1) - 5y = 15

3 - 5y = 15 ( subtract 3 from both sides )

- 5y = 12 ( divide both sides by - 5 )

y = - [tex]\frac{12}{5}[/tex]

Answer: Easy, graph and solution

Step-by-step explanation: First what you want to do  use the slope intercept form to find the slope and y intercept; -1/2 and y intercept (0,4). Any line can be graphed using 2 points. Select two x values, plug them into the equation to find the corresponding y values. Solution

1.) Step; x and y

Answer:

z=2

Step-by-step explanation:

This equation is being read as (z+22)/z=12 which we can solve:

(z+22)/z=12

z+22=12z

22=11z

2=z

z=2

Therefore, the unknown number is z=2

Answer:

Slope: 3/2

Y-intercept: 3

Step-by-step explanation:

Because the equation is set up as mx+b, the slope is actually just the number in front of x, and the y-intercept is 3

Answer:

3.82 miles per inch are listed in the legend.

Step-by-step explanation:

Given that:

Actual distance = 145 miles

Distance on map = 38 inches

38 inches = 145 miles

We have to find the number of miles represented by 1 inch.

1 inch on legend = [tex]\frac{Actual\ distance}{Distance\ on\ map}[/tex]

1 inch on legend = [tex]\frac{145}{38}[/tex]

1 inch on legend = 3.82 miles

Hence,

3.82 miles per inch are listed in the legend.

Answer:

2/5

Step-by-step explanation:

Total=4+5+1=9+1=10

4/10=2/5

2/5 is the correct answer

Solution

( − 2)(3 + 5)

Step-by-step solution:

Use the sum-product pattern

3x^2−−10

3^2+5−6x−10

Common factor from the two pairs

3^2+5−6−10

(3+5)−2(3+5)

Rewrite in factored form

(3+5)−2(3+5)

(−2)(3+5

Answer:

The new mean is: 11.8

Step-by-step explanation:

Given the data set

2.4  1.6  3.2  0.3  1.5

Sum of terms = 2.4 + 1.6 + 3.2 + 0.3 + 1.5 = 9

Number of terms = 5

We know that the mean of a data set is the sum of the terms divided by the total number of terms, so

Mean = Sum of terms / Number of terms

substituting Sum of terms = 9 and Number of terms = 5

         = 9/5

          = 1.8

Thus, the Mean = 1.8

We need to determine the mean when each piece of data is increased by 10.

All we need is to add 10 in the determined mean to determine the new mean.

New Mean = Mean + 10

                   = 1.8 + 10

                   = 11.8

Therefore, the new mean is: 11.8

VERIFICATION:

When each piece of data is increased by 10

[tex]2.4+10+1.6+10+3.2+10+0.3+10+1.5+10=59[/tex]

so,

[tex]\frac{59}{5}=11.8[/tex]

Answer:

25[tex]x^{4}[/tex]y²

Step-by-step explanation:

The area (A) of a square is calculated as

A = s² ( s is the side length )

A = (5x²y)²

  = 5 × 5 × x² × x² × y × y

  = 25[tex]x^{4}[/tex]y²

The product of the expression 6(x² - 1)(6x - 1)/6(x + 1) is equal to (x - 1)(6x - 1).

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The expression 6(x^2 - 1)(6x - 1)/6(x + 1) can be simplified by canceling out common factors:

6(x^2 - 1)(6x - 1)/6(x + 1)

= (x^2 - 1)(6x - 1)/(x + 1)

= [(x - 1)(x + 1)] * [6x - 1]/(x + 1)

= (x - 1)(6x - 1)

Thus,

The product of the expression 6(x² - 1)(6x - 1)/6(x + 1) is equal to (x - 1)(6x - 1).

Answer:

Step-by-step explanation:

The question is phrased oddly, asking “how far *can* the ladder be from the wall,” instead of “how far *is* the ladder from the wall.”

Draw a picture. The 15-foot ladder is the hypotenuse of a right triangle. The vertical leg of the triangle is 13 feet.

By the Pythagorean Theorem, the remaining leg is √(15²-13²) ≈ 7.5 feet.

Note that the ladder *can* be 7.5 feet from the wall, but it *shouldn’t* be. The angle to the ground is 60°, when the recommended angle is 75°. That makes it. 3.9 feet
