Answer:
1/2 or 0.5 (same value, different form)
Step-by-step explanation:
Ok...since I can't actually graph it, we can make a table out of it....
x y
7 -1
9 0
From -1 to 0, we add 1 (this is for the y section)
From 7 to 9, we add 2 (this is for the x section)
Now all we have to do is divide the y with the x
y/x = 1/2
The slope will be 1/2 (fraction form) 0.5 (decimal form)
Hope this helped!
Answer:
28 miles
Step-by-step explanation:
308/11 = 28 miles per gallon of gas
Given:
Base of a right triangle = 7 in
Height of a right triangle = a
Hypotenuse = 16 in
To find:
The length of side a.
Solution:
Using Pythagoras theorem:



Subtract 49 from both sides.


Taking square root on both sides, we get
a = 14.4
The length of side a is 14.4 in.
Answer:
Joseph tenía 240 soles
Step-by-step explanation:
Tenemos lo siguiente
Cantidad total = Cantidad gastada + Cantidad restante.
Sabemos que Cantidad gastada = 3/5 Cantidad restante y que Cantidad restante = Cantidad gastada + 60.
Sea x la cantidad gastada e y la cantidad restante. Tenemos las ecuaciones

Reemplazando la segunda en la primera, tenemos que
(aquí simplemente distribuímos la multiplicación.
Restando 3/5 x a ambos lados, tenemos que

Multiplicando por 5 y dividiendo por dos ambos lados, tenemos que

Es decir, Joseph gastó 90 soles. Entonces y = 90+60 = 150 soles.
Es decir, en total, Joseph tenía 150+90= 240 soles.
Our polynomial is

We can tell from -28 that the binomials are one positive and one negative.
We can use a factoring chart. What adds to make +3x and multiplies to make -28.

To get a negative 28, we can multiply -4 and positive seven, which add together after being multiplied by x to get +3x. Therefore, you are left with (x+7) and (x-4).
