what values of a and b would make shown below have infinitely many solutions aX +6=-3x+b

Answer: P= 2{(12x+7) + (9x+11)} or 42x + 36

Step-by-step explanation:

The formula for the perimeter of a rectangle is P=2(l+w)

P= 2{(12x+7) + (9x+11)}

Simplified to 42x + 36

Answer:

the positive 17 is the problem. so it should be: -17 + (-31) = -48

Step-by-step explanation:

if 17 is positive, the equation is just: -14 = -48 (which isnt correct)

Answer:

[tex] \boxed{ \bold{ \huge{\boxed{ \sf{x = 4}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ - 8 - x = x - 4x}[/tex]

Collect like terms

⇒[tex] \sf{ - 8 - x = - 3x}[/tex]

Move 3x to left hand side and change it's sign

Similarly, move 8 to right hand side and change it's sign

⇒[tex] \sf{ - x + 3x = 8}[/tex]

Collect like terms

⇒[tex] \sf{2x = 8}[/tex]

Divide both sides of the equation by 2

⇒[tex] \sf{ \frac{2x}{2} = \frac{8}{2} }[/tex]

Calculate

⇒[tex] \sf{x = 4}[/tex]

Hope I helped!

Answer:

[tex]\large\boxed{x^{36}}[/tex]

Step-by-step explanation:

Consider the properties:

[tex]\boxed{(x^a)^b=x^{a\cdot b}}[/tex]

[tex]\boxed{x^a \cdot x^b=x^{a+b}}[/tex]

[tex]\therefore (x^3)^6 \cdot (x^2)^9= x^{18} \cdot x^{18}= x^{36}[/tex]

Answer is 36

(x3)6 * (x2)9

x3*6x2*9

Answer:

The mistake she made was ; She didn't change the sign when subtracting -3/4 from both sides

She wrote 5/4+3/4 instead of 5/4-3/4

Step-by-step explanation:

Correct solution:

[tex] \frac{3}{4} + m = \frac{5}{4} [/tex]

Subtract-3/4 from both sides

[tex] \frac{3}{4} - \frac{3}{4} + m = \frac{5}{4} - \frac{3}{4} [/tex]

Simplify

[tex]m = \frac{5}{4} - \frac{3}{4} \\ m = \frac{1}{2} [/tex]

The mistake Angela made was when she subtracted -3/4 from both sides, she didn't change the sign and She wrote 5/4 + 3/4 instead of 5/4-3/4.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that performs the arithmetic operations are called arithmetic operators.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

We have given the expression as

⇒ 3/4 + m = 5/4

The mistake Angela made was when she subtracted -3/4 from both sides, she didn't change the sign.

She wrote 5/4 + 3/4 instead of 5/4-3/4

Here is the correct work :

Subtract 3/4 from both sides from the equation,

⇒ 3/4 + m - 3/4 = 5/4 - 3/4

⇒ m = (5 - 3)/4

⇒ m = 2/4

⇒ m = 1/2

Answer:23 mm

Step-by-step explanation:

add both 15 and 8 because they are as long as the one on the bottom

Answer:

70

Step-by-step explanation:

find the small unknown side by subtracting the two sides across from it. 12-7=5. add the 15 and 8 for the big unknown side. 15+8=23. add all the sides. 12+15+7+8+5+23=70

Answer:

K = 13.15 cm^2

Step-by-step explanation:

Sides:

a = 8 cm

b = 3.75631 cm

c = 7 cm

Angles:

A = 90.9699 °

B = 28 °

C = 61.0301 °

Other:

P = 18.7563 cm

s = 9.37816 cm

K = 13.1452 cm^2

r = 1.40168 cm

R = 4.00057 cm

Agenda: A = angle A

B = angle B

C = angle C

a = side a

b = side b

c = side c

P = perimeter

s = semi-perimeter

K = area

r = radius of inscribed circle

R = radius of circumscribed circle

Answer:

7) refer to d=rt triangle so answer is t= d/r

8) rearrange by dividing so it should be PV/nR = T

9) move 5r to  other side which become 2p = q - 5r then divide by 2. final answer is p = q-5r/2

10) multiply both side by b/1 so b got cancel on left side

right side become c(b/1) which is same as cb

then you divide both side by c to isolate b on the right side

final answer is a/c=b

Answer:

  ∠CBD = 125°

Step-by-step explanation:

The angle sum theorem tells you that ...

  ∠ABC +∠CBD = ∠ABD

  8x -41° +9x +17° = 180° . . . . . . a "straight angle" has a measure of 180°

  17x -24° = 180° . . . simpify

  17x = 204° . . . . . . add 24°

  x = 12° . . . . . . . . . . divide by 17

Now the measures of the angles can be found from their expressions.

  ∠ABC = 8(12) -41° = 55°

  ∠CBD = 9(12) +17° = 125°

Answer:

g(x) = x - 7

Step-by-step explanation:

g(x) is the same as saying "y".

you need to move the y-intercept down 7 units, therefore putting the term - 7 into the expression.

Answer:

g(x) = x-7

Step-by-step explanation:

First find f(x)

f(x) is the function  y =x

f(x) = x

g(x) = f(x) + C  C < 0 moves it down

We want to move it down 7 units

g(x) = f(x)  -7

g(x) = x-7

'dz' because d and z are different values.

Answer:

t-t

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

Given that G is directly proportional to h then the equation relating them is

G = kh ← k is the constant of proportion

To find k use the condition h = 40 when G = 2200, then

2200 = 40k ( divide both sides by 40 )

55 = k

1

G = 55h ← equation of proportion

11

When h = 22, then

G = 55 × 22 = 1210 joules

111

When G = 3025, then

3025 = 55h ( divide both sides by 55 )

h = 55 m

Answer:

(-3,-2)

Step-by-step explanation:

Starting at the point (1, 0)

Now we move don 2 units (so the y-value reduces in two units) making now the point (1,0-2)  which is (1, -2)

then we move to the left 4 units (so the x-value has now to be decreased in 4 units) making the point: (1-4, -2) which is (-3, -2)

Answer:

It would be -2,4.

Step-by-step explanation:

you start at (1,0) and go down 2 to -2 then left 4 you would land on -2,4

Step-by-step explanation:

5x - 6y = 17

5x - 17 - 6y = 0

5x - 17 = 6y

y = [tex]\frac{5x - 17}{6}[/tex]

Answer:

Hey there!

Original Equation: 5x-6y=17

Subtract 5x: -6y=17-5x

Multiply by -1: 6y=5x-17

Divide by 6: y= [tex]\frac{5x-17}{6}[/tex].

Step-by-step explanation:

3(7+a) = 24

3*7 + 3*a = 24

21 + 3a = 24

3a = 24 - 21

3a = 3

a = 3/3

a = 1

Answer:

[tex]\huge\boxed{TS = 10.5}[/tex]

Step-by-step explanation:

Given that:

R is a point lying on line TS

So,

TS = TR + RS

Where TR = 4.5 and RS = 6

=> TS = 4.5 + 6

=> TS = 10.5

Step-by-step explanation:

You know that 9 = 10 - 1.

Then 9 of something is equal to 10 of it less one of it. Here, that "something" is four.

Comment on this math

This illustrates a shortcut for multiplying by 9 that can be convenient for mental arithmetic. The idea is to multiply by 10, which just involves adding 0 (or moving the decimal point), then subtract the original number.

Answer:

  11. HJ = 79; JK = 50

  12. HJ = 1; JK = 14

Step-by-step explanation:

The segment addition postulate tells you the total length is the sum of the segment lengths.

__

11. HJ + JK + HK

  (6x -5) +(4x -6) = 129

  10x = 140 . . . . add 11

  x = 14 . . . . . . . divide by 10

  6x -5 = 6(14) -5 = 79 = HJ

  4x -6 = 4(14) -6 = 50 = JK

__

12. HJ + JK = HK

  (4x -15) +(5x -6) = 15

  9x = 36 . . . . . add 21

  x = 4 . . . . . . . .divide by 9

  4(4) -15 = 1 = HJ

  5(4) -6 = 14 = JK

Answer: c

First you organize the numbers into order then you find the middle of both. The middle of Williams was 89. Then you do the same for Andres and you get 82. To get the difference of them both you have to subtract both of them to get 7 and that’s c.
