Subtract 8.5.

Answers

Answer 1
Answer:

Subtract 8.5 from both sides to solve equation.

What is a expression? What is a mathematical equation?

  • A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.
  • A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correctanalysis, observations and results of the given problem.

We have the following equation -

y + 8.5 = 17.2

y + 8.5 - 8.5 = 17.2 - 8.5

y = 8.7

Therefore, Subtract 8.5 from both sides to solve equation.

Answer 2
Answer:

Answer:

Subtract 8.5

Step-by-step explanation:

To solve the equation, y has to be isolated (only y will be on one side of the equation)

To do this, we have to get rid of the 8.5, so it has to be subtracted from both sides.

So, the correct answer is subtract 8.5

Find the area of the circle. Use 3.14 for pi.Question 1 options:


113.04 in2


56.52 in2


256.34 in2


1017.36 in2

Answers

Answer:

The answer is 254.34in².

Step-by-step explanation:

Given that the diameter is 2 times the radius. So the radius will be 9 in. Next, you have to find the area of circle, A = π × r² :

A = π × r²

Let π = 3.14, r = 9,

A = 3.14 × 9²

A = 254.34 in²

A rectangle has vertices (−5, 6), (−1, 6), (−1, 3), and (−5, 3). It is first dilated by the rule (x, y)→(7x, 7y) and then translated 10 units down. What are the coordinates of the image?A(−35, 32), (−7, 32), (−7, 11), (−35, 11)


B(−45, 42), (−17, 42), (−17, 21), (−45, 21)


C(−105, 42), (−77, 42), (−77, 21), (−105, 21)


D(−35,−28), (−7,−28), (−7,−49), (−35,−49)

Answers

Final answer:

By first dilating and then translating the given coordinates of the rectangle, we obtain the final coordinates as (−35, 32), (−7, 32), (−7, 11), (−35, 11). The correct answer is A.

Explanation:

The process of dilation involves multiplying the x and y coordinates of each vertex of the rectangle by a certain factor. In this case the factor is 7, which gives us the following set of coordinates after dilation: (−35, 42), (−7, 42), (−7, 21), (−35, 21). After the dilation, the rectangle is then translated down 10 units, which involves subtracting 10 from each of the y-coordinates. Following the translation, the final set of coordinates of the rectangle is (−35, 32), (−7, 32), (−7, 11), (−35, 11). Therefore, the correct answer is A.

Answers

Answer:

f(x) = 8·1.25^x

Step-by-step explanation:

An exponential function has the form ...

... f(x) = a·b^x

Then f(0) = a. Your graph shows f(0) = 8.

The base "b" can be found from any other point on the graph. You have marked the point (1, 10), so we can find "b" from ...

... f(1) = 10 = 8·b^1 = 8b

... 10/8 = b = 1.25 . . . . . . . divide by the coeffiicient of b

Now, we know the exponential function is ...

... f(x) = 8·1.25^x

Answer:

The correct answer is f(x) = 8·1.25^x
