Step-by-step explanation:

56⋅x>616−224

56⋅x>616-224

Simplify :

56⋅x>392

56⋅x>392

Dividing by the variable coefficient :

x>

392

56

x>39256

Simplify :

x>7

x>7

Joe is at the ice cream shop, and his house is 10 blocks north of the shop. The park is 10 blocks south of the ice cream shop. W
Furkat [3]

Answer:

The distance between the ice cream shop and Joe's house is the same as the distance between the ice cream shop and the park. So Joe is not closer to the park or his house, he is in the middle.

Step-by-step explanation:

We consider that the ice cream shop is the zero value in the number line. We assume that going north is positive (right side of the number line) and going south is negative (left side of the number line).

The house position is 10 block north of the ice cream shop, so it is represented by the integer 10.

The park is 10 blocks south of the ice cream shop, so it is represented by the integer -10.

The lower absolute value of the integer, the closer position from the ice cream shop.

If we calculate the absollute value of the House position:

|10|=10

Then, we calculate the the absollute value of the Parkposition

|-10|=10

In conclusion, the distance between the ice cream shop and Joe's house is the same as the distance between the ice cream shop and the park. Joe is in the middle.

Step-by-step explanation:

AC⊥BC

BD=BC=x

  • (x+5)²+x²=7²
  • x²+10x+25+x²=49
  • 2x²+10x- 24=0
  • x²+5x-12=0
  • x=1.8

BC= 1.8 cm

Area of ABC= 1/2*1.8*7= 6.3 cm²

For an exponential regression equation in the form y=ab^x which of the following values of b will cause y to get smaller as x ge
sdas [7]

Answer:

d) 0.798

Step-by-step explanation:

Since we know that an exponential function is in form: y=a*b^x, where,

a= Initial value,

b = For growth b is in form (1+r), where r is rate in decimal form.

b = For decay or regression b is less than 1 and in form (1-r), where r is rate in decimal form.

Upon looking at our given choices we can see that options a, b and c are in form 1+r, while choice provided in option d is less than 1 and in form 1-r, therefore, option d is the correct choice.
