Help!!!
I need the answer please

Given b equals -3, determine if it is a solution to 4b - 6 = - 18.

So, we have our given which is b = -3, and we are asked to determine if it a solution to the above equation.

To do this, we can plug -3 in for b and see if it works out.

Work:

Plug in -3 for b.

4(-3) - 6 = - 18

-12 - 6 = -18

-12 - 6 = - 18

Thus, b = -3 is a viable solution for the equation of 4b - 6 = -18.

Answer:

f(n) = 120 * (1/2)^n

Step-by-step explanation:

First the first number is 120, so we get y = 120, then 60/120 = 1/2

So we no the r, or constant rate is 1/2.

After that, we can finish our equation by doing

f(n) = 120 * (1/2)^n

or

y = 120*(1/2)^x

The explicit formula for the given geometric sequence is:

[tex]a_n = 120 \times 0.5^{n-1}[/tex]

We have,

To find an explicit formula for the geometric sequence 120, 60, 30, 15, ...,

we need to determine the common ratio, denoted by 'r'.

To find the common ratio, we divide any term in the sequence by its preceding term.

Let's choose the second and first terms:

r = 60 / 120 = 0.5

Now that we have the common ratio 'r', we can express the nth term of the geometric sequence using the explicit formula:

[tex]a_n = a_1 r^{n-1}[/tex]

where '[tex]a_n[/tex]' represents the nth term of the sequence, '[tex]a_1[/tex]' is the first term, 'r' is the common ratio, and 'n' is the position of the term we want to find.

Using the given sequence, '[tex]a_1[/tex]' is 120, and 'r' is 0.5.

Plugging these values into the formula, we have:

[tex]a_n = 120 \times0.5^{n-1}[/tex]

Therefore,

The explicit formula for the given geometric sequence is:

[tex]a_n = 120 \times 0.5^{n-1}[/tex]

Answer:

1/27

Step-by-step explanation:

3 times 3 times 3 = 27

as a fraction it would be 1/27

Answer:

[tex]\frac{1}{27}[/tex]

Step-by-step explanation:

When finding the power of a fraction you need to set both the numerator and denominator to the power.

(1/3)³ = 1³/3³

3³ = 27

1³/3³ = 1/27

First we, Subtract the 16 from 2x ( which we can't do) so we change the equation to 16 - 2x = 4y

Second we, solve for x.  x = −2y + 8, We divide both sides by 2,

-2y/-2= y ( The two -2s cancle each other ) 8/2= 4

x = 4

Next we, solve for y. y = 4 −x/2y, we multiply both sides by 2y,

4 * 2y = 8y ( LOL ) -x/2y * 2y = -x

NOW WE have 8y - x

IDK anything beyond this I'm SORRY T.T

The pie chart that represents the people who prefer dogs will have an angle of 172.8 degrees. The correct option is C.

A circular statistical visual with slices illustrating numerical proportion is called a pie chart. Each slice's arc length in a pie chart corresponds to the quantity it represents.

The data for the pie chart is given below:-

Dogs          24

Cats           18

Hamsters   5

Fish            3

Total number is = 24 + 18 + 5 + 3 = 50

Angle = 360 / 50 = 7.2

The pie chart that represents the people who prefer dogs will be calculated as:-

Dogs = 7.2 x 24 = 172.8 degrees.

The pie chart is attached with the answer below.

Answer:

y= 5x +9

Step-by-step explanation:

Slope- intercept form:

y= mx+c, where m is the gradient and c is the y-intercept.

Parallel lines have the same gradient. Since the gradient of the given line is 5, the gradient of the unknown line is also 5. Hence, m=5.

y= 5x+c

To find the value of c, substitute a coordinate.

When y= -6, x= -3,

-6= 5(-3) +c

-6= -15 +c

c= 15 -6 (+15 on both sides)

c= 9 (simplify)

Thus, the equation of the line is y=5x+9.

So the answer is no solution .

Answer:

biobooks = 204

mathbooks = 68

Step-by-step explanation:

the bio textbooks make up 3 parts

the math textbooks make up 1 part

the denominator therefore is 4

so biobooks = 272 * 3/4

and mathbooks = 272 * 1/4 (272 : 2 : 2)

note that calculating the mathbooks 1st is easier, bc you can then multiply by 3 to get the biobooks.

add both numbers up to proof that the sum is 272

Answer:

Graph A

Step-by-step explanation

I look at the y-intercept first, and the y-intercept is -4, so looking at each graph you can see both A and D have y-intercepts of -4, since the line intercepts, or goes through the y-axis (the vertical line of the graph) at -4.

Then, you look at the variable that's changing, which is -5x. Since it's a negative, A is the graph that is negatively decreasing, because of its position on the graph. The line is going down, starting in the negative side.

Four more than some number                 C) b+4

An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc.

Let's analyze each statement separately:

- Four less than an unknown value --> this means that we have to subtract 4 to an unknown value. Calling  the unknown value, it means we have to write y-4

- Quotient of a variable and four --> this means we have to divide a variable by 4. Calling  the unknown variable, it means we have to write

z/4

- Some number to the power of four --> this means that we have to write the power of a number, in the form , where m in this case is equal to 4. Calling  the unknown number, it means we have to write a⁴

- Four times an unknown value --> this means that we have to multiply an unknown value by 4. Calling  our unknown values, we have to write 4x

- Four more than some number --> this means we have to add 4 to an unknown number. Calling  the unknown number, it means we have to write b + 4

Answer:

y + 1/2 = 3(x - 2)          This matches the 3rd answer choice.

Step-by-step explanation:

Use the point-slope formula for the equation of a straight line that passes through the point (h, k) and has a slope of m:

y - k = m(x - h) becomes:

y + 1/2 = 3(x - 2)          This matches the 3rd answer choice.

The equation of the line will be y + 1/2 = 3(x – 2). Then the correct option is C.

The equation of line is given as

y = mx + c

Where m is the slope and c is the y-intercept.

The slope is 3. Then the equation of line will be

y = 3x + c

If the equation is passing through (2, -1/2). Then we have

-1/2 = 3(2) + c

    c = -6 - 1/2

Then the equation will be

        y = 3x – 6 – 1/2

y + 1/2 = 3(x – 2)

Then the correct option is C.
