A negative to a even power is always

Answer:

- 16k + 28

Step-by-step explanation:

3 - 2(k - 2) - 7(2k - 3) ← distribute parenthesis

= 3 - 2k + 4 - 14k + 21 ← collect like terms

= - 16k + 28

Answer:28−16k

Step-by-step explanation:

3−2(k−2)−7(2k−3)

Use the distributive property to multiply −2 by k−2.

3−2k+4−7(2k−3)

Add 3 and 4 to get 7.

7−2k−7(2k−3)

Use the distributive property to multiply −7 by 2k−3.

7−2k−14k+21

Combine −2k and −14k to get −16k.

7−16k+21

Add 7 and 21 to get 28.

28−16k

Oh ok

Step-by-step explanation:

An expression is defined as a set of numbers, variables, and mathematical operations. The given statement "Double the product of eight and a number" in the form of an expression can be written as 16x.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Let the unknown number be represented by x.

The product means multiplication, therefore, we need to double or multiply the product or multiplication of eight and x.

Thus, The given statement in the form of an expression can be written as,

2(8 × x)

= 2(8x)

= 16x

Hence, the given statement "Double the product of eight and a number" in the form of an expression can be written as 16x.

Answer:

Step-by-step explanation:

let the eq. of parabola be

y=ax²+bx+c

points (-1,0),(2,0),(3,4) and (0,-2) lie on it.

0=a-b+c

0=4a+2b+c

subtract

3a+3b=0

a=-b

4=9a+3b+c

-2=0+0+c

c=-2

a-b-2=0

-b-b-2=0

-2b-2=0

b+1=0

b=-1

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

eq. of parabola is

y=x²-x-2

Answer:

The numbers are (x,y)=(-5,8) or (8,-5)

Step-by-step explanation:

Let two numbers be x and y,

We have,

x+y=3

x=3-y---(i)

Now,

xy=-40

(3-y)y=-40 [From (i)]

3y-y^2=-40

y^2-3y-40=0

Factoring,

(y + 5) (y - 8)=0

Either,

y+5=0        or,      y-8=0

y=-5                      y=8

When y=-5,

x=3-y

3--5

3+5

8

When y=8,

x=3-y

3-8

-5

Answer:

1.) x = -5

   y = -4

Point to graph: (-5, -4)

2.) x = 0

    y = -6

Point to graph: (0, -6)

3.) x = 5

    y = 8

Point to graph: (5, 8)

Step-by-step explanation:

Substitute x for the given value, then find y.

1.) -2(-5)-5y = 30

10-5y = 30

-5y = 20

y = -4

2.) -2(0)-5y = 30

-5y = 30

y = -6

3.) -2(5)-5y = 30

-10-5y = 30

-5y = 40

y = -8

Answer:

y values are

-4

-6

-8

Step-by-step explanation:

y = 4x - 6

x = 4y - 6; must solve for y in order to solve for inverse function

x + 6 = 4y

(x + 6)/4 = y

or

(x/4) + (6/4) = y

y = (x/4) + 3/2

hope this helps <33

have a nice day :)

Answer:

x = 8

Step-by-step explanation:

All angles of a triangle must add up to 180 degrees.

So 8x + 7 + 6x + 8x - 3 = 180

Combine like terms

22x + 4 = 180

Subtract 4

22x = 176

Divide

22x ÷ 22 = 176 ÷ 22 = x = 8

We can make sure this is correct by plugging in 8 for all x terms.

8(8) + 7 + 6(8) + 8(8) -3

64 + 7 + 48 + 64 - 3 = 180.

X = 8

Hope this helps.

Answer:

150°
