$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \:y-6 = 3(x + 2)$

____________________________________

$\large \tt Solution \: :$

Equation of line in point - slope form :

$\qquad \tt \rightarrow \:y-y_1 = m(x - x_1)$

$\tt \:m = slope=3$

$\tt y_1 = y \: \: coordinate \: \: of \: \: point = 6$

$\tt \:x_1 = x \: \: coordinate \: \: of \: \: point = - 2$

Here :

$\qquad \tt \rightarrow \:y - 6 = 3(x - ( - 2))$

$\qquad \tt \rightarrow \:y - 6 = 3(x + 2)$

A children's birthday party at a indoor play center cost $50 to rent the space and 6.25 per child. Gina wants to spend no more t

scZoUnD [109]

Answer:

The number of children (n) that can attend the birthday party can be expressed as;

n≤8

Step-by-step explanation:

Step 1

We can use the expression below to calculate the total cost of the party as shown;

C≥F+(V×n)

where;

C=total cost of Gina is willing to spend

F=fixed cost for the rent

V=cost per child

n=number of children at the party

In our case;

C=$100

F=$50

V=$6.25

n=n

replacing;

100≥50+(6.25×n)

6.25 n+50≤100

6.25 n≤100-50

6.25 n≤50

n≤50/6.25

n≤8

The number of children (n) that can attend the birthday party can be expressed as;

n≤8

Answer:

Step-by-step explanation:

The picture is a bit blurry, but from what i can see, i'd say C (whichever one has -4 x 3 x 1 under the square root.)

So for this, you need to know the quadratic formula, which is:

$\frac{-b ± \sqrt{b^{2} -4ac} }{2a}$

*ignore the weird capital A, it keeps coming up when i try to use the ± symbol

They have given you the equation of a quadratic, so the first thing you have to do is rearrange it, so that $x^{2}$ comes first.

So now we have the equation: 3 $x^{2}$  - 2x +1

*the quadratic formula uses a, b and c, but they are specific. a is always the coefficient of $x^{2}$ , b is always the coefficient of x and c is always the constant (number without an x)

So, i can find that, in this case:

a = 3 b= -2 c=1

Now substitute each of those values it into the original quadratic equation:

$\frac{-(-2) ± \sqrt{(-2)^{2} -4(3)(1)} }{2(3)}$

*again, ignore the weird capital A.

That's how you find the answer, which from what i can tell in the picture is C.

Hope that helped : )

Plz help me ASAP I will give Brainliest if right. What is the probability that he gets a number less than 4 or A multiple of 4?

mezya [45]

Answer:

5/8

Step-by-step explanation:

The sectors are labeled 1,2,3,4,5,6,7,8

Numbers less than 4: 1,2,3

Multiples of 4: 4,8

We are looking for 1,2,3,4,8 = 5 choices

P (1,2,3,4,8) = Number of choices/ total

= 5/8
