Answer:

x = 11

Step-by-step explanation:

In this question, you would solve for x.

Solve for x:

7(x - 4) = 4x + 5

Use the distributive property.

7x - 28 = 4x + 5

Subtract both sides by 4x.

3x - 28 = 5

Add 28 to both sides.

3x = 33

Divide both sides by 3.

x = 11

Your final answer would be x = 11

Answer:

x=11

Step-by-step explanation:

First, do the parentheses (PEMDAS).

7(x-4)=4x+5 to 7x-28=4x+5

Then, add 28 to either side to get all the numbers on one side.

7x-28=4x+5 to 7x=4x+33

After that, subtract 4x to get all the x's on one side.

7x=4x+33 to 3x=33

Finally, divide by 3 to get your final answer.

3x=33 to x=11

Answer:

r = 85

Step-by-step explanation:

conclusion:

so the value of r is 85

Step-by-step explanation:

First, divide both sides of the equation by -6.

-6(r-98)÷6=78÷6

This gives us r-98=-13

Then, add 98 to both sides.

r-98+98=-13+98

The answer is r=85

Answer:

y = 6x + 104

Step-by-step explanation:

Given the equation in the form:

y = mx + b

m = slope ; b = intercept

Given the data:

5 days - $134 10 days - $164 15 days - $194 20 days - $224

To obtain the slope, Pick the points :

(5, 134) and (20, 224)

Slope = y2 - y1 / x2 - x1

Slope, m = (224 - 134) / (20 - 5) = 90 / 15 = 6

Plugging into the equation :

We have ;

y = 6x + b

Picking any point from the data and plugging in to solve for b:

(10, 164)

164 = 6(10) + b

164 = 60 + b

b = 164 - 60

b = 104

Equation finally becomes ;

y = 6x + 104

Answer:

Step-by-step explanation:

(f∘g)(x) = f(g(x))

 = f(x²-3)

 = 2(x²-3) + 1

 = 2x² - 5

(f∘g)(-2) = 2(-2)² - 5

  = 2·4 - 5

  = 8 - 5

  = 3

The composition (f ∘ g)(–2) for the functions f(x) = 2x + 1 and g(x) = x2 –  3 will be 3

The composition of a function is an operation where two functions say f and g generate a new function say h in such a way that h(x) = g(f(x)). It means here function g is applied to the function of x. So, basically, a function is applied to the result of another function.

The notation used for composition is: (f o g)(x) = f(g(x))

(fog)(x) = f(g(x))

this implies , (fog)(-2) = f(g(2))

given :

f(x) = 2x + 1

g(x) = x2 – 3

(fog)(x) = f(g(x)) = f(x^2 - 3)

                        =  2 (x^2 -3) +1

                        = 2x^2 - 5                                    equation 1

fog(-2) =  f(g(2))

substituting the value of x = 2 in equation 2

           = 2 * (2)^2 -5

           = 3

Answer:

18/3 or 6

Step-by-step explanation

9/1 and 9 is the same thing and because we are multiply fractions you add the 9/1 so it makes 9/1 x 2/3.

9/1 x 2/3 = 18/3

18/3 = 6

Hope it makes sense!  

Answer:

Ans: 5.94

Step-by-step explanation:

according to bodmas,

we should solve division first then

multiply it with 9.

So,

= 9 × 2/3

= 9 × 0.66

= 5.94 ~ 6(approx)

Answer:

factoring out the 1/2 (that is the coefficient of the variable) would require you to divide the equation by one half, which is the same as multiplying by two. After doing this, the answer can be expressed as:

1/2 (d+12)

Answer:

d

Step-by-step explanation:

in order for it to be a triangle the angles have to add up to equal 180

5+75+100=180 so its not a

10+80+90=180 so its not b

20+60+100=180 so its not c

45+45+45=135 so its d because the angles dont add up to 180

50+50+80=180 so its not e

Answer:

D

Step-by-step explanation:

To be a triangle, you have to have 180 degrees. if you add up all of the sides, it should give you 180. If it doesn't, it isn't a triangle. I hope that helped! :)

Answer:

112 degrees

Step-by-step explanation:

Since the two sides opposite of angle 1 and 2 are congruent, as shown by the double tic marks, the angles are conguent. The total sum of all angles must be 360 degrees, so we know 90 degrees was given, as well as 46 degrees. That's 136 degrees together, subtract that from 360 and you get 224. Angles 1 and 2 are congruent so both add to 224, therefore each angle is 112 degrees.

Answer:

C. a= 4, b= 2

Step-by-step explanation:

In a parallelogram, opposite sides are equal.

So, 4a+1 = 2a+9

On solving, we get, a= 4

Similarly, 6b= 11b-10

On solving, we get, b= 2

Answer:

answer: option C: a=4,b=2

explanation:

opposite sides of a parallelogram are equal so,

QP =RS

6b=11b-10

I. e 6b-11b = -10

I. e. -5b = -10

I. e. - b = -10/2

I. e -b = -2

by removing minus sign from both the sides...

b =2

again opposite sides of a parallelogram are equal so,

QR =PS

4a + 1 = 2a + 9

I. e 4a- 2a = 9 - 1

I. e 2a = 8

I. e a = 8/2

therefore a= 4

so the answer is a=4 and b= 2
