8a2 + 6a = 5
how do I do this?

Answers

Answer 1

Answer: $8a^2 + 6a = 5 \n \n8a^2 + 6a -5 =0\n \n\Delta = b^(2)-4ac = 6^(2)-4*8* (-5)=36 +160=196\n \na_(1)=(-b-√(\Delta ))/(2a) =(-6- √(196))/(2*8)=(-6- 14)/(16)= (-20)/(16)=- (5)/(4)=-1(1)/(4)\n \na_(2)=(-b+√(\Delta ))/(2a) =(-6+√(196))/(2*8)=(-6+14)/(16)= (8)/(16)= (1)/(2)$

The graphs of f(x) and g(x) are shown below:If f(x) = (x + 7)^2, which of the following is g(x) based on the translation?

g(x) = (x + 9)^2
g(x) = (x + 5)^2
g(x) = (x − 9)^2
g(x) = (x − 5)^2

Answers

The function that is based on the translation is g(x) = (x + 5)^2

How to determine the translation?

The function f(x) is given as:

f(x) = (x + 7)^2

The function f(x) is translated 2 units right to get function g(x)

This means that:

g(x) = f(x - 2)

So, we have:

f(x - 2) = (x -2 + 7)^2

Evaluate

f(x - 2) = (x + 5)^2

This gives

g(x) = (x + 5)^2

Hence, the function that is based on the translation is g(x) = (x + 5)^2

If you can choose one scoop of ice cream and one topping, how many different sundaes can you make?A. 3
B. 2
C. 5
D. 6
E. 8

Answers

Answer:

Step-by-step explanation:

What is the answer??????

Final answer:

Calculate the total number of sundae combinations by multiplying the number of ice cream scoop choices by the number of topping choices. The specifics are not provided in the question, so the answer varies.

Explanation:

The number of sundae combinations you can make will be determined by the total number of ice cream flavors and the total number of toppings you have to choose from. If we consider each flavor and each topping as a single option, this becomes a problem of counting combinations. The general rule is that if you have 'n' options for one thing (like ice cream scoops) and 'm' options for another thing (like toppings), you multiply them together for the total number of combinations. So far the exact options are not specified in your question, so the correct answer could be any of the options you've provided depending on the specifics of cone and topping choices.

What is the perimeter of a rhombus-shaped street sign with a 35-cm side? A. 280 cm
B. 140 cm
C. 1,225 cm
D. 70 cm

Answers

A rhombus has a total of 4 sides. All sides are equal. The formula of getting the perimeter of a rhombus is:
Perimeter = 4 * S
Perimeter = 4 * 35 cm
Perimeter = 140 cm.

So the perimeter of a rhombus-shaped street sign that has a 35-cm side is equal to (B) 140 cm.
