Answer:

The measure of angle BCD is 68.5\°

Step-by-step explanation:

step 1

Find the value of x

we know that

m -----> form a straight line

substitute the values

(3x+4)\°+(6x-8)\°+(7x-20)\°=180\°

(16x-24)\°=180\°

16x=180\°+24\°

16x=204\°

x=12.75\°

step 2

Find the measure of angle BCD

m

substitute the value of x

m

A line has a slope of a and has a y-intercept of (0,b). Which equation represents this line?
Papessa [141]

Step-by-step explanation:

General line equation: y = mx + c, where m is the slope of the line and c is the y-intercept.

We have y = ax + b.

=> y - b = ax

=> y - b = a(x - 0).

The answer is option A.

Alexus [3.1K]

Answer:

\dfrac{\$1000+\$20x}{x} \leq \$25

Minimum 200 people other than the 2 charity representatives.

Step-by-step explanation:

Given that:

The venue can hold a maximum of 500 people.

Cost of venue = $1000

Per person cost for food = $20

Two charity representatives get to attend the dinner for free.

To find:

The inequality and to determine how many people must come to keep costs at most $25.

Solution:

Let the number of people attending the dinner = x

Cost of food for x people = \$20x

Total cost = $1000 + \$20x

Cost per person = Total cost divided by Number of people attending the dinner.

As per question statement:

\dfrac{\$1000+\$20x}{x} \leq \$25\\\Rightarrow 1000+20x\leq25x\\\Rightarrow 1000 \leq 5x\\\Rightarrow x\geq 200

Therefore, the answer is:

Minimum 200 people other than the 2 charity representatives should attend the dinner.

I di not understand these any help greatly appreciated thank you
Rzqust [24]

Answer:

Step-by-step explanation:

First you need to convert it to a linear expression.

3x - y = 4

+3x        +3x

-1y = 3x + 4

---  ----- -----

-1     -1    -1

y = -3x -4

6x - 2y = 7

-6x         -6x

-2y = -6x + 7

----    -----   -----

-2       -2     -2

y = 3x - 3.5

-3x - 4 = 3x - 3.5

+3x         +3x

-4 = 6x - 3.5

+3.5       +3.5

-0.5 = 6x

-----   -----

6         6

-0.5

------ =  x

6
