Solve the system of equation. Write the solution as a coordinate point.

Answers

We can just substitute y = 4x+1 in the second equation.

[tex]6x-2(4x+1)=-3\\6x-8x-2=-3\\6x-8x-2+3=0\\-2x+1=0\\-2x=-1\\x=\frac{1}{2}[/tex]

We know the value of x, substitute x in any equations to get the y-value.

[tex]4x+1=y\\4(\frac{1}{2})+1=y\\2+1=y\\3=y[/tex]

The value of y is 3 and the value of x is 0.5 aka 1/2

Since you want the solution as a point then It's below here.

John's garden is 12ft long and 15ft wide. How
long is John's garden in yards?

Answers

Answer:

4 yards long

Step-by-step explanation:

John's garden is 12 ft long and 3 ft go into a yard. With this information you then divide 12 by 3 to see how many yards would go into the 12. 12/3=4

Answer:

Step-by-step explanation:

3ft = 1yd

They only want to know how long in yards not the rest so

12ft = ?yds

So set up the problem.

12/3 = x/1

Solve

1(12) = 12

12 divided by 3 = 4

John's garden is 4yds long

Which set of data points represents an exponential function?

Answers

Answer:

Step-by-step explanation:

In the data set in option D, the x-values are equally spaced, (i.e. [tex] \delta x = 1 [/tex], however, the x-value are not equally spaced. This rules out the possiblity of the data set in option D being a linear function.

To confirm if it's an exponential function, let's examine if the data set has a "constant multiplying factor", n, that takes us from one y-value to a successive y-value.

Thus:

What do we multiply ⅑ with that will give us the next successive y-value, 1?

Thus, let n be the constant multiplying factor we are looking for.

Therefore:

⅑ × n = 1

Solve for n. Multiply both sides by 9

n = 9.

If we multiply the second y-value which is 9, by 9, wwe will get the next successive y-value, which is 81.

This means the data set has a constant multiplying factor of 9.

Therefore, the data set in option D represents an exponential function.

A. 9 + 5t
B. 5 ▪ t + 9
C. (9 + 5)t
D. (5 × t) + 9
E. 5 + 9t

Answers

Answer:

9 + 5t

Step-by-step explanation:

Nine more means 9 plus (9+)

after the 9+, it says 5 times the number of t. That means 5*t, or 5t.

putting them together, you get 9+5t

Answer:

A. 9 + 5t

sophia scored 92 percent in a math test. If the test had 50 questions, how many did she get right?

Answers

Answer:

Sophia got 46 questions right.

Step-by-step explanation:

Heres why:

In order to find how much she got right, we put 92% over 100 and make it a fraction so that would be 92/100.

Now, she had 50 questions. So, we will put that over 1. So that would look like this: 50/1.

Finally, we multiply: 92/100 times 50/1.

This equals 4600/100 which equals 46

SO: Sophia got 46 questions right! Hope this helps and plz mark brainliest if you want to! :)

The completed construction of a regular hexagon is shown below. Explain why AACF is a
30°-60°-90° triangle. Show a picture, please!

Answers

Answer:

You can prove that angle C is 30°. This is because we know that angle B is 120° also, and interior angles add to 180°, which makes angle BCF 60°. Then we can divide this by 2 as angle BCF is bisected by AC, so, therefore, angle ACF is 30° as 60 ÷ 2 = 30.

You can then prove angle A is 90°. First, we can find angle BAC because it is part of a triangle, and angles in a triangle add to 180°. This means we can do 30 + 120 = 150, and 180 - 150 = 30° which is angle BAC. Then we do 120 - 30 = 90, as the whole of angle BAF is 120°.

Answers

Answer:

f(x) = 19

Step-by-step explanation:

f(x) = 2x2 + 1

f(x) = 2(3)2 + 1

f(x) = 2(9) + 1

f(x) = 18 + 1

f(x) = 19
