write the equation in standard form of the line that passes through the point (1,26) and has a slope of -0.4
katovenus [111]
The beginning formula that you start with is y=m(x)+b
after the problem is written into the formula your ready to start.

It should look like this:

26y=-0.4(1)+b

to get the entire formula you've gotta find the
y-intercept or "b"

to start solving multiply the "m" by the "x" A.K.A:

-0.4×1

you should come up with the answer -0.4 since everything multiplied by 1 is still the same thing depending on if its positive or negative

after you've finished solving the multiplication part the equation should look slightly different like this:

26y=-0.4+b

the next step is the get "y" by itself since right now is a variable.

also you should always remember what ever process of simplifying by the same number to get rid of it in a "y=m(x)+b" equation should be done the same to the other side

take a look at the "-" sign in front of 0.4 this would mean that you are going to do the oppisite opperation to cancel it out so you would be adding the same number to either side. after adding the -0.4 to itself that would leave "b" by itself the problem should now look like this:

(26y+0.4)=b

forget about the y for now and focus on the (26+0.4)
you should get 26.4=b

insert this into the original equation of "y=m(x)+b" and this should look like this:

y=-0.4(x)+12.4

A cell phone company charges a monthly fee of $10 for the first 1600 text messages and 30 cents for each additional text message
Tomtit [17]
1875 messages because she already sended 1600 messages which is $10 so u subtract 10 from 92.50 which equals 82.50 which divided by .30 is 275 messages and 275 plus 1600 is 1875.

Does 2 1/3-1 3/4 need require renaming
ANEK [815]

Answer:

\frac{7}{12}

Step-by-step explanation:

2 \frac{1}{3}  - 1 \frac{3}{4}

The fractions above are known as mixed numbers (that is, fractions that contain the combination of a whole number and proper fraction). The mixed numbers can equally be renamed as improper fractions. However, renaming can only occur the the mixed numbers are being transformed as below:

\frac{7}{3}  -  \frac{7}{4}

The transformation occur through a simple approach thus: for the first mixed number; 2 1/3 = 2 multiplied by 3 plus 1 divide by 3 equals 7/3. Similarly, mixed number 1 3/4 is transformed by this: 1 multiplied by 4 plus 3 divide by 4 equals 7/4.

Simplifying further to arrive at final result implies,

\frac{7}{3}  -  \frac{7}{4}

Take the LCM of the denominators (4 × 3 =12) and simplify thus:

=   \frac{28 - 21}{12}

=  \frac{7}{12}
