Write an expression for "12 times 1."

Answer:

Step-by-step explanation:

17.  2(x+6)  common factor is 2

18.  8(3+y-2w) common factor is 8

19. 2(7-4m)

Answer:

y = 7x - 12

Step-by-step explanation:

Parallel lines have same slope.

y = mx + b

m - > slope   & b -> y-intercept

y = 7x

So, slope = 7 & (2 , 2)

y - y1 = m(x -x1)

y - 2 = 7(x - 2)

y - 2 = 7x - 14

    y = 7x - 14 + 2

   y = 7x - 12

Answer:

550a + 590b = 1275

Step-by-step explanation:

We use the following relation to solve this question:

[tex]v = \frac{d}{t}[/tex]

In which v is the velocity, d is the distance and t is the speed.

In this question, we find the distance, so we use:

[tex]d = v*t[/tex]

A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City.

This means that [tex]d = 1275[/tex].

Write an equation in standard form to represent the situation if the plane travels a hours at 550 mph and b hours at 590 mph.

This means that [tex]v*t = 550a + 590b[/tex].

Which equation is correctly written in standard form to represent this scenario?

[tex]d = v*t[/tex]

1275 = 550a + 590b

550a + 590b = 1275

Answer:

Leg= Leg- hypotenuse

Step-by-step explanation:

5 suquared= 25

13 squared= 169

25+169 =194

194 square root is 13.9

How to determine each side of a right triangle

if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)

if leg b is unknown, then. b = √(c² - a²)

for hypotenuse c missing, the formula is. c = √(a² + b²)

Answer:

13.9 (rounded)

Step-by-step explanation:

The pathaegorean theorem is A²+B²= C²

5²=25

13²= 169

169+25=194

√194=13.9

Answer:

Answer:

x would be 54 degrees

Step-by-step explanation:

Since x lies on a straight line, and it gives you the other angle (126) just subtract 180 and 126.

180 - 126 = 54

Answer:

430 cm³

Step-by-step explanation:

= 11 × 10 × 2

= 220 cm³

= 10 × 3 × (9-2)

= 210 cm³

= 220 + 210

= 430 cm³

Answer:

430 cubic centimeters

Step-by-step explanation:

Lets start by separating both figures. Start with the one in the back, which is the bigger one.

Given:

Length = 10 cm

Width = 3 cm

Height = 9 cm

This is a rectangle and the volume of a rectangle is L x W x H. Therefore,

Volume = 10 x 3 x 9 = 270 cubic centimeters

Now we move on to the second figure.

Given:

Length = 10 cm  (Given from the other rectangle)

Width = 8 cm (We do 11 - 3 since we separated the rectangles)

Height = 2 cm

Using the same formula we get the following.

Volume = 10 x 8 x 2 = 160 cubic centimeters

____

Finally, we add both volumes back since we separated the figures in the beginning.

Volume = 270 + 160 = 430 cubic centimeters

Answer:

∫[tex]6x^5(x^6-2)\,dx[/tex] = [tex]\frac{1}{2}(x^6-2)^2+C[/tex]

Step-by-step explanation:

To find:

∫[tex]6x^5(x^6-2)\,dx[/tex]

Solution:

Method of substitution:

Let [tex]x^6-2=t[/tex]

Differentiate both sides with respect to [tex]t[/tex]

[tex]6x^5\,dx=dt[/tex]

[use [tex](x^n)'=nx^{n-1}[/tex]]

So,

∫[tex]6x^5(x^6-2)\,dx[/tex] = ∫ [tex]t\,dt[/tex] = [tex]\frac{t^2}{2}+C_1[/tex] where [tex]C_1[/tex] is a variable.

(Use ∫[tex]t^n\,dt=\frac{t^{n+1} }{n+1}[/tex] )

Put [tex]t=x^6-2[/tex]

∫[tex]6x^5(x^6-2)\,dx[/tex] = [tex]\frac{1}{2}(x^6-2)^2+C_1[/tex]

Use [tex](a-b)^2=a^2+b^2-2ab[/tex]

So,

∫[tex]6x^5(x^6-2)\,dx[/tex] = [tex]\frac{1}{2}(x^6-2)^2+C_1=\frac{1}{2}(x^{12}+4-4x^6)+C_1=\frac{x^{12} }{2}-2x^6+2+C_1=\frac{x^{12} }{2}-2x^6+C[/tex]

where [tex]C=2+C_1[/tex]

Without using substitution:

∫[tex]6x^5(x^6-2)\,dx[/tex] = ∫[tex]6x^{11}-12x^5\,dx[/tex] = [tex]\frac{6x^{12} }{12}-\frac{12x^6}{6}+C=\frac{x^{12} }{2}-2x^6+C[/tex]

So, same answer is obtained in both the cases.

Answer:

[tex]y=\frac{1}{2} x+\frac{5}{2}[/tex]

Step-by-step explanation:

First find the slope using the slope using the given points. Remember that the slope is the change in y over the change in x.  

[tex]\frac{6-2}{7- (-1)}=\frac{4}{8}=\frac{1}{2}[/tex]

So now we have the equation [tex]y=\frac{1}{2} x+b[/tex], and we need to find out what b is. We can do this by pointing a point (either one, but I'll use -1,2) into the equation

[tex]2=\frac{1}{2}(-1)+b[/tex]

Rearrange the equation so it equals b

[tex]\frac{5}{2}=b[/tex]

Put it together and that's the final equation!

[tex]y=\frac{1}{2} x+\frac{5}{2}[/tex]

Answer:

9 ft and 26 ft

we will take as x the width, then

P rect. = 2(A+B)

A = 2x + 8 | 2×x, because there is b twice less, and + 8, because there is at 8 longer

B = x

70 = 2(2x + 8 + x)

70-16 = 4x + 2x

54= 6 x

54/6 = 9 => B = 9; A = 2×9+8 = 26

Answer:

8.26 or 8.3 (If Rounded)

Step-by-step explanation:

When I'm dealing with problems involving fractions. I turn the fractions to decimals. So, on a calculator, just do 3/4, you'll get 0.75.

Then, the problem would be 6.2 ÷ 0.75 = 8.26

the answer is,

541.42%
