Answer:

y=3/4x+2

Step-by-step explanation:

you have the plot (0,2) so you add 2 to the end of the equation

from that plot you have to find how to get to plot (4,5) right? you move right 3 points and then move up 4 to get the plot (4,5). you put that as the x variable

leaving you with y=3/4x+2

Quadriatic formula 2w^2-28w=-98

alina1380 [7]

To apply the quadratic formula, the right side must be equal to 0.

$2w^2-28w=-98 \\ 2w^2-28w+98=0$

Now you can apply the quadratic formula $\frac{-b\±\sqrt{b^2-4ac}}{2a}$ to find the solution for w.

$\frac{-(-28)\±\sqrt{(-28)^2-4(2)(98)}}{2(2)} = \frac{28\±\sqrt{784-784}}{4} = \frac{28}4 = \boxed{7}$

(The quadratic formula is highly unnecessary in this problem, however. You could easily divide all values by 2 to get w²-14w+49=0, which factors into (w-7)²=0, for which 7 is the only solution which puts a factor of the quadratic equal to 0.)

Given ∠A= 210° and ∠B= 4 radians, which angel is bigger? justify your response.

8090 [49]

Answer:

∠B

Step-by-step explanation:

To convert from radians to degrees, multiply the radians by 180°/π

⇒ ∠B = 4 × 180°/π

⇒ ∠B = 229.2° (nearest tenth)

As 229.2° > 210° then ∠B is bigger than ∠A

Which inequality does the graph represent?<br>1. x>17<br>2.x<17<br>3.x<_17<br>4.x>_17

TiliK225 [7]

Answer:

1. x > 17

Step-by-step explanation:

When the point on the graph is an open circle you are going to be using < or > as an open circle means greater than or less than

Immediately we can eliminate number 3 and 4

When the line is going in the direction of the right than the inequality sign will face the variable (x)

the numbers are getting larger meaning that x is greater than the constant (17)

Hence, your answer is x > 17

Extra notes:

when the point on the graph is a closed circle ( filled in ) then you will use ≤ or ≥ as a closed circle means greater than or equal to or less than or equal to

How would the following problem be represented using colored tiles? -7 + (-3) seven red tiles plus three blue tiles seven red ti

Lelechka [254]

Answer:

Ok, we have the equation:

-7 + (-3)

Both numbers are negative, so the solution of this will be:

-7 + (-3) = -7 - 3 = -10.

Now, how we can represent it with tiles?

First we need to define, which tiles are the ones representing negative numbers?

We can use:

Red = positive

Blue = negative.

Then:

-7 is represented with seven blue tiles

-3 is represented with tree blue tiles

then:

(-7) + (-3)

will be represented with seven blue tiles, plus tree blue tiles.

When we add them, we have a total of 10 blue tiles, and as blue tiles represent negative numbers, 10 blue tiles is equal to -10.
