Answer:

14d + 12c + 3

Step-by-step explanation:

1) Add the same variables; if you see d, or c variable add or subtract them like this:

16d + 5d - 7d = 14d

20c - 8c = 12c

3 is left alone b/c there’s no any other number to add/subtract for 3.

also I know whether to add or subtract b/c the addition or subtraction sign would be before the number: ex; - 2, - 3x, + 5d, + 5

2) your equation should look like this....

14d + 12c + 3

Answer:

12c + 14d - 4

Step-by-step explanation:

16d + 20c + 5d -7 - 8c - 7d + 3

Simplify the expression

__________________________

To solve, we need to first take in mind the fact that there are different like terms within this expression. Like terms are numbers or values that end in different symbols, such as variables or exponents. Since we are filled with variables such as c and d. We can do as followed :

Combine the "d" like terms :

16d + 5d - 7d

21d - 7d

14d

Combine the "c" like terms :

20c - 8c

12c

Combine the constants :

-7 + 3

-4

Now add all of the values together to get the final expression.

12c + 14d - 4

Darya [45]

Answer:

The rule is y = -7x + 5

→ Other values of x;

  • -9

→ Other values of y;

  • 5
  • -2
  • -9
  • -12
  • 28
  • 68
  • -170

Step-by-step explanation:

» Take points (1, -2) and (3, -12) from the table.

☑ General equation of a line is y = mx + c

  • m is the slope
  • c is y-intercept

✍<u> </u><u>F</u><u>o</u><u>r</u><u> </u><u>s</u><u>l</u><u>o</u><u>p</u><u>e</u><u>,</u><u> </u><u>m</u><u> </u>:

{ \tt{slope =  \frac{ - 12 - 2}{3 - 1} }} \\  \\ { \tt{slope =  \frac{ - 14}{2} }} \\  \\ { \tt{m =  - 7}}

✍<u> </u><u>For</u><u> </u><u>y-intercept</u><u>,</u><u> </u><u>c</u><u> </u>:

{ \tt{y = mx + c}}

» Taking point (1, -2):

{ \tt{ - 2 = (1 \times  - 7) + c}} \\ { \tt{c =  - 2 + 7}} \\ { \tt{c = 5}}

{ \boxed{ \tt{y =  - 7x + 5}}}

Find the missing side of this triangle, round to the nearest tenth if needed PLEASE HELP WILL MARK BRAINLIEST
serious [3.7K]

Answer:

The value of x:

  • x\:\approx \:8 in

Step-by-step explanation:

Given

b=4.8 in

c=9.3 in

a = x

we have to determine 'x'.

As the given triangle is a right-angled triangle.

Pythagorean Theorem:

For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as

c=\sqrt{a^2+b^2}

so

a=\sqrt{c^2-b^2}

as

  • b=4.8 in
  • c=9.3 in
  • a = x

substituting the values

x=\sqrt{9.3^2-4.8^2}

x\:\approx \:8 in

Thus, the value of x:

  • x\:\approx \:8 in
