What is the slope of this line?
Answer:
A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .
A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .
If a line is horizontal the slope is zero. This is a constant function.
If a line is vertical the slope is undefined (see below).
42 = y + 15 whats y? y == __
Solution
[tex]y=27[/tex]
Step-by-step explanation:
Subtract [tex]15[/tex] from both sides of the equation:
[tex]42=y+15[/tex]
[tex]42[/tex][tex]-15=y+15[/tex][tex]-15[/tex]
Simplify:
Subtract the numbers:[tex]42-15=y+15-15[/tex]
[tex]27=y+15-15[/tex]
Subtract the numbers:[tex]27=y+15[/tex][tex]-15[/tex]
[tex]27=y[/tex]
Move the variable to the left:[tex]27=y[/tex]
[tex]y=27[/tex]
[tex]y=27[/tex]
(16/25)-3/2 help me solve
Answer:
-43/50
(decimal) = -0.86
Step-by-step explanation:
Find the LCD which is 50.
16/25 will be multiplied by 2 (because 25 x 2 = 50) so it will then equal 32/50
3/2 will be multiplied by 25 (2 x 25 = 50) = 75/50
subtract them which will give you -43/50

.- Sí 159.6 gramos de Fe2O3 liberan 67.2 litros de CO2 ¿cuántos litros de CO2 se liberan si reaccionan 45 gramos de Fe2O3? de acuerdo a la siguiente reacción: Fe2O3 (s) + 3 CO (g) 2 Fe (s) + 3 CO2 (g)
Answer:
45 g de oxido de hierro (III) liberarán 18.9 L de CO₂
Step-by-step explanation:
La reaccion quimica es la siguiente:
Fe₂O₃ (s) + 3CO (g) → 2Fe (s) + 3CO₂ (g)
1 mol de oxido de hierro (III), reacciona con 3 moles de monoxido de carbono para liberar 3 moles de CO₂ y 2 moles de Fe sólido.
Pasamos la masa de F₂O₃ a moles:
159.6 g . 1 mol /159.7g = 1 mol de oxido
Entonces, aplicamos la regla de tres:
1 mol de oxido produce 3 moles de dioxido de carbono, indudablemente eso será lo que formemos de producto, por lo tanto 3 moles de CO₂ estan ocupando 67.2 litros.
Ahora calculamos los nuevos moles:
45g . 1 mol /159.7 g = 0.282 moles
Aplicamos la regla de tres:
Si un mol de oxido produce 3 moles de CO₂
0.282 moles producen (0.82 . 3 ) = 0.845 moles de CO₂
Como tenemos menos moles de gas, el volumen ocupado sera mayor, hacemos la regla de tres:
Si 3 moles de CO₂ ocupan 67.2 litros
0.845 moles ocuparan (0.845 . 67.2/ 3 ) = 18.9 litros

Solve the following equation:
1.3(a + 2) + 5.6 = 17.3
Answer:
a=7
Step by step Explanation:
Step 1: Simplify both sides of the equation.
1.3(a+2)+5.6=17.3
(1.3)(a)+(1.3)(2)+5.6=17.3(Distribute)
1.3a+2.6+5.6=17.3
(1.3a)+(2.6+5.6)=17.3(Combine Like Terms)
1.3a+8.2=17.3
1.3a+8.2=17.3
Step 2: Subtract 8.2 from both sides.
1.3a+8.2−8.2=17.3−8.2
1.3a=9.1
Step 3: Divide both sides by 1.3.
1.3a 9.1
1.3 = 1.3
a = 7
