Find the slope of the line on the graph.

Mathematics

1 answer:

Rasek [7]3 years ago

The slope should be -1/2, because the line goes down 1 unit and then right 2 units.

Also it would be y = -1/2x+1 in y=mx+b.

which is the equation for the linear function f in the form f(x) = mx + b that has the given values? f(-2) = - 8, f(3) = 7

Xelga [282]

The information we have is:

$\begin{gathered} f(-2)=-8 \\ f(3)=7 \end{gathered}$

So we can find that two coordinates are ( -2,-8 ) and ( 3,7 ) so we can use the equation to find the slope so:

$\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{7-(-8)}{3-(-2)} \\ m=\frac{15}{5} \\ m=3 \end{gathered}$

So the equation now will be:

$y=3x+b$

So we can replace one coordinate to find b so:

$\begin{gathered} 7=3(3)+b \\ 7=9+b \\ 7-9=b \\ -2=b \end{gathered}$

So the final equation is:

$y=3x-2$

In triangle QRS QT=5 and TS=22 what is RT? Explain!!

Anton [14]

Answer:

$\large\boxed{RT=\sqrt{110}\approx10.49}$

Step-by-step explanation:

ΔTQR and ΔTRS are similar (AA). Therefore the sides are in proportion:

$\dfrac{RT}{QT}=\dfrac{TS}{RT}$

We have QT = 5m ans TS = 22m. Substitute:

$\dfrac{RT}{5}=\dfrac{22}{RT}$ cross multiply

$RT^2=(5)(22)$

$RT^2=110\to RT=\sqrt{110}$

Which numbers are integers and which are not 71,-9,-42/7,-94.8,19/5

Liula [17]

Answer:

Step-by-step explanation: integers are whole numbers , it could be positive or negative.

Therefore 71 and - 9 are integers

- 42/7 written in this form is a Rational number , but when divided , it will give -6 which is an integer.

-94 . 8 is not an integer

19/ 5 is not an integer, it is a rational number
