1 answer:

4 0

Answer:

10x + 7 = 85

8 packs

Step-by-step explanation:

Let's let packs = x

10 shirts in a pack = 10x

So we know that since he has 7 packs already, that can be our y-intercept in this equation

This will leave us with 10x + 7

And since we can't have a partial amount of packs, we round up to 8 total packs

Hope this helps

What is the equation, in standard form, of a parabola that models the values in the table?
serg [7]

Answer:

Equation of parabola is: y=4x^{2} +3x-6

Step-by-step explanation:

By plotting a rough graph with the values given we get an opening upward parabola.

Standard equation for a parabola opening upwards is given by:

y=ax^{2}+bx+c

We can solve for a,b,c by substituting the given values of x and y.

Putting x=0 and y=-6 in the above equation,we get:

c = -6

Putting x=-2 and y=4, we get:

4a-2b=10  ---------1

Putting x=4 and y=70, we get:

16a+4b=76 --------2

Solving equation 1 and 2, we get

a=4 and b=3

Hence y=4x^{2} +3x-6

What is the smallest integer that can be divided by the product of a prime number and 7 while yielding a prime number?
11111nata11111 [884]

Answer:

(D). 28

Step-by-step explanation:

We have been given that the smallest integer that can be divided by the product of a prime number and 7 while yielding a prime number.  

We know that smallest prime is 2. The product of 2 and 7 is 14.

Let us divide our given numbers by 14.

(A) 7.

\frac{7}{14}=\frac{1}{2}

The quotient is not a integer or prime number.

(B). 14

\frac{14}{14}=1

We know that 1 is not a prime number.

(C) 24.

\frac{24}{14}=\frac{12}{7}

The quotient is not a integer or prime number.

(D). 28

\frac{28}{14}=2

Since 2 is a prime number, therefore, 28 is the smallest integer that can be divided by the product of a prime number and 7 and yield a prime number.

TS = 4x - 7

x = -7/4

SV = 5x -15

x = -15/5

= -3

TV = -7/4 + -3

= -3 3/4

= -4.75
