Answer:

Each term in an algebraic expression is separated by a + sign or J sign. In , the terms are: 5x, 3y, and 8. When a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient. In the term 5x, the coefficient is 5.

A coefficient is a number that is next to a variable. Let’s say the variable is x and the equation is 3x+4. The coefficient would be 3 because it is the number next to the variable. The constant is a number that is not associated with the variable. The constant in the equation above would be 4.

10. Not sure what the question is. Looks like it could be to write 9/5 in decimal form? In that case, we have 1/5 = 0.2, so 9/5 = 9*0.2 = 1.8

11. $52.\overline{23}=52.232323\ldots$ . If we round to 5 decimal places, the approximate value is 52.23232

12. By long division, we can show that $\dfrac{4.3}9=0.4777\ldots$ . In repeated decimal notation, that's $0.4\overline7$

Which equation has a graph that is a parabola with a vertex at (–1, –1)?

Artist 52 [7]

Answer:

$y=(x+1)^2-1$

which agrees with the last option listed.

Step-by-step explanation:

We use the vertex form of a parabola:

$y-y_v=a(x-x_v)^2$

which with the information we have becomes:

$y-y_v=a(x-x_v)^2\\y-(-1)_v=a(x-(-1))^2\\y=a(x+1)^2-1$

Therefore the equation that corresponds to such vertex (-1, -1) is the last one listed among your given answer options.

$y=(x+1)^2-1$
