Right angles will be formed because in drawing
the perpendicular lines they all form right angles
to begin with. With several more draw it will
still be the same as if you are drawing one
the answer is -right angles
Your question answers itself. You solve by graphing.
I like to subtract one side of the equation from the other, so the solutions are where the graph crosses the x-axis (the resulting function value is zero).
It can be useful to find the "turning point" of each absolute value expression (where its value is zero) and graph that and some points on either side.
8 ounces* 20 days= 160 ounces
160 ounces divided by 16 ounces in a pound= 10 pounds
She will have fed tiny 10 pounds of dog food in 20 days.
Answer:
a) 1.
Step-by-step explanation:
Supongamos que el primer número entero positivo es a tal que a ∈ Z⁺.
Luego, el conjunto de los cinco enteros positivos se puede expresar como
A = {a; a+1; a+2; a+3; a+4}
Dada la condición del problema, se debe cumplir que
a + (a+1) + (a+2) = (a+3) + (a+4)
⇒ 3a + 3 = 2a + 7
Resolviendo la ecuación resulta
a = 4
Luego, el conjunto A nos resulta
A = {4; 5; 6; 7; 8}
Puede concluirse que sólo un conjunto cumple con esta condición.
Answer:
The number is 7. If you divide -28 by -4 you get 7, 7×-4=-28
