I believe C is right, he is adding 5 words each month, although I could be wrong.

Answer:

Option (c) is correct.

Total after m months , his typing speed will be (180+5m) words per minute.

Step-by-step explanation:

Given: Donald can currently type 180 words per minute, and

believes that with practice he can increase his typing speed by 5 words per minute each month.

We have to express the given statement mathematically and choose the correct answer from the given options.

Since, Donald is able to type 180 words per minute currently.

And given his typing speed increases 5 words per minute each month.

If he typed for m months he can write 5m words.

So, Total after m months , his typing speed will be (180+5m) words per minute.

4ab +10b

Step-by-step explanation:

Perhaps you want to simplify the expression.

$(2.5ab+14b)-(-1.5ab+4b)=2.5ab+14b+1.5ab-4b\\\\=ab(2.5+1.5)+b(14-4)=\boxed{4ab+10b}$

What is the initial value in the function 2x + 3y = 6?

Galina-37 [17]

THE INITIAL VALUE IN THE FUNCTION ARE X=0 AND Y=2 OR X=3 AND Y=0.

Step-by-step explanation:

The initial value of the line segment is the value at which X=0 .

X=0 means nothing but a Y-intercept.

Now set X=0, in the function 2x+3y=6

2(0)+3y=6.

3y=6.

Therefore Y=2

so (0,2) is one point on the graph or line segment.

similarly considering X=3 in the line segment and that means Y=0.

Y=0 indicates X-intercept.

substituting X=3 in the function

2(X)+3(0)=6

2X=6

Therefore X=3

so (3,0) is another point on the line segment or graph.

An equation is shown below: 1 over 2 multiplied by x plus 3 over 2 equals 2 to the power of x What is the solution to the equati

Alborosie

Answer:

First option is correct. The solution of the equation is x=1.

Step-by-step explanation:

The given equation is

$\frac{1}{2}x+\frac{3}{2}=2^x$

The value of x, which satisfy the above equation is the solution of the given equation.

Put x=1 in the given equation.

$\frac{1}{2}(1)+\frac{3}{2}=2^{1}$

$\frac{1+3}{2}=2$

$\frac{4}{2}=2$

$2=2$

Since left hand side is equal to right side, therefore first option is correct.

Put x=2 in the given equation.

$\frac{1}{2}(2)+\frac{3}{2}=2^{2}$

$\frac{2+3}{2}=4$

$\frac{5}{2}=4$

Since left hand side is not equal to right side, therefore second option is correct.

Put x=4 in the given equation.

$\frac{1}{2}(4)+\frac{3}{2}=2^{4}$

$\frac{4+3}{2}=16$

$\frac{7}{2}=16$

Since left hand side is not equal to right side, therefore third option is correct.

Put x=8 in the given equation.

$\frac{1}{2}(8)+\frac{3}{2}=2^{8}$

$\frac{8+3}{2}=256$

$\frac{11}{2}=256$

Since left hand side is not equal to right side, therefore fourth option is correct.
