C+a=630

a=630-c

2c+5a=2910 using a found above in this we have:

2c+5(630-c)=2910

2c+3150-5c=2910

-3c+3150=2910

-3c=-240

c=80

So 80 children attended the concert.

Janelle graphed a line through (−6, 5) that had a slope of −79. What is the y-coordinate of a point on the line that has an x-co
jeyben [28]

Answer:

The value of the y-coordinate is -706

Step-by-step explanation:

The equation of a straight line is;

y = mx + c

where m is slope and c is t-intercept

Given the slope, we can write the equation as;

y = -79x + c

we need to get c

Just put in the x and y values of the given point

X = -6 and y = 5

5 = -79(-6) + c

5 = 474 + c

c = 5-474 = -469

So the complete equation of the line would

be ;

y = -79x - 469

To get the y-coordinate of the point, just insert the x value into the equation;

y = -79(3) - 469

y = -237 - 469 = -706

kenny6666 [7]

Answer:

The required probability is, \simeq 0.06729

Step-by-step explanation:

Of 24 employees at a local supermarket, 13 work as cashiers  and 11 stock shelves. If 4 employees are selected at random to work overtime, then

P( all 4 are cashiers) = \frac{^{13}{C}_{4}}{^{24}{C}_{4}}

                                 \simeq 0.06729
