Answer:
1.a part, share, or number considered in comparative relation to a whole.
1/3 = 2/6
2.If a proposition is true, then we say it has a truth value of "true"; if a proposition is false, its truth value is "false". For example, "Grass is green", and "2 + 5 = 5" are propositions. The first proposition has the truth value of "true" and the second "false".
3.
Don't confuse cross multiplication with cross cancellation. You use cross cancellation to make multiplying fractions easier. Set the two cross products equal to each other. 1 · 2 = 2 and 0.5 · f = 0.5f.
I know it is a triangle so 12×7=84÷2=42
Answer:
y=5/4x-11
Step-by-step explanation:
tenemos un punto (4,-6) y una pendiente equal a 5/4.
usa la ecuación y=mx+b (m es la pendiente, b es el y interceptar)
porque sabemos la pendiente es 5/4, ahora mismo la ecuación es:
y=5/4x+b
en el punto, x=4, y=-6
podemos sustituir los números en la fómula para resolver b
-6=4(5/4)+b
-6=5+b
-11=b
entonces,
la ecuación de la recta es y=5/4x-11

Answer:
g(x) = -4x^2 +(45/2)x +6
Step-by-step explanation:
A function is scaled horizontally by replacing x with x/k, where k is the expansion factor. Here, we want to expand the graph horizontally by a factor of 2, so the new function will be f(x/2).
g(x) = f(x/2) = -16(x/2)^2 +45(x/2) +6
g(x) = -4x^2 +(45/2)x +6
