hello i need the answer what is the product of 15/16

Answers

Answer:

The product is 240.

Step-by-step explanation:

The product is always when you multiply numbers together.

Answer:

Using 15 times table, we have 15 times 8 = 15 × 8 = 120. Hence, 15 times 8 is 120. b) First, we will write 15 times 7 minus 5 mathematically.

Table of 15 up to 20.

15 × 11 = 165 15 × 16 = 240

15 × 14 = 210 15 × 19 = 285

15 × 15 = 225 15 × 20 = 300

Find the solution of the system of equations.
2.x + 4y = -14
– 2y = 9

Answers

Answer:

x = 4, y = -9/2 (-4.5)

Step-by-step explanation:

Using the second equation, we can divide both sides by -2 and get

y = 9/-2

y = -9/2

Then, we plug this y value into the first equation and get:

x + 4(-9/2) = -14

Simplify:

x - 18 = -14

x = 4

does anyone know how to do this?

All angles of a triangle equal 180

180 - 70 - 60 = 50

8x+2 = 50

x = 6

Answer:

x = 6

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

70 + 60 + 8x + 2 = 180 , collect like terms

132 + 8x = 180 ( subtract 132 from both sides )

8x = 48 ( divide both sides by 8 )

what is [tex]−3.64⋅|5.3|−1.5^3[/tex]

Answers

Answer:

- 22.667

Step-by-step explanation:

1.5^3 = 1.5 x 1.5 x 1.5 = 3.375

- 3.64 ⋅ | 5.3 | - 1.5^3

= ( - 3.64 ⋅ | 5.3 | ) - 1.5^3

= ( - 3.64 ⋅ 5.3 ) - 1.5^3

= ( - 3.64 x 5.3 ) - 1.5^3

= - 19.292 - 3.375

= - 22.667

write the equation of the line from the given information (-2,4) & (-3,5)

Answers

Step 1: Find the slope

Slope Formula = (y2 - y1) / (x2 - x1)

Point 1 = (-2, 4)

Point 2 = (-3, 5)

slope = (5 - 4) / (-3 - - 2) = (5 - 4) / (-3 + 2) = (1) / (-1) = -1

Step 2: Find the y-intercept

To find the y-intercept, we will take one of the given points as well as the slope and plug them into slope-intercept form. Then, we will solve for b.

Slope-Intercept Form: y = mx + b

Point = (-2, 4)

Slope = -1

4 = -1(2) + b

4 = -2 + b

b = 6

Step 3: Put it all together

Now that we have the slope and the y-intercept, all that's left to do is plug it into slope-intercept form.

Slope-Intercept Form: y = mx + b

Slope = -1

Y-Intercept = 6

y = -x + 6

Answers

Answer:

x ≤ -12

Step-by-step explanation:

to solve for 'x', since it is getting multiplied by 1/4, you must multiply it by the inverse which is 4

whatever gets multiplied to one side of the inequality must also get multiplied to the other side

you will get:

x ≤ -12

20. Write the following equation in slop intercept form. -4x-3y=-18.
21. Write the following equation in slope intercept form. -2x+3y=21

please show your work and thank you.

Answers

Step-by-step explanation:

slope intercept form y=mx+b

you just need to move the letters and numbers around to match this.

-4x-3y=-18

add 4x to both sides of the equal sign

-3y =4x-18

divide by negative 3 on both sides

y = -4/3x + 6

21. -2x+3y=21

add 2x to both sides

3y = 2x + 21

divide by 3 on both sides

y = 2/3x +7

Answers

Answer:

You compare it by this

Step-by-step explanation:

Linear functions are graphed as straight lines while exponential functions are curved. Linear functions are typically in the form y = mx + b, which is used to discover the slope, or simply the change in y divided by the change in x, while exponential functions are typically in the form y = (1 + r) x.

A factory makes 84 toys robots in a day after they purchase new equipment now they make 205 robots a day

Answers

Based on the given information the percent gain is 144%.

Initial production rate = 84 toy robots per day

Present production rate = 205 robots per day

Using this formula

Percent gain=  Increase in production rate /Initial production rate× 100  

Where:

Increase in production rate = 205 - 84 =121

Initial production rate = 84 toy robots per day

Let plug in the formula

Percent gain=121/84×100

Percent gain=144%

Inconclusion the percent gain is 144%.

consider the linear function f(x)=4x-5 Find the values of x for which f(x)=3,f(x)=5,f(x)=-3

Answers

Answer:

f(2) = 3

f(5/2) = 5

f(½) = -3

Step-by-step explanation:

Given the linear function f(x) = 4x - 5:

f(x) = 3

3 = 4x - 5

3 + 5 = 4x - 5 + 5

8 = 4x

8/4 = 4x/4

2 = x

Therefore, when f(x) = 3, x = 2.

f(x) = 5

5 = 4x - 5

5 + 5 = 4x - 5 + 5

10 = 4x

10/4 = 4x/4

5/2 = x

Therefore, when f(x) = 5, x = 5/2.

f(x) = -3

-3 = 4x - 5

-3 + 5 = 4x - 5 + 5

2 = 4x

2/4 = 4x/4

½ = x

Therefore, when f(x) = -3, x = ½.
