A linear equation has more than one intercept. what can you conclude about the graph of the equation?

1 answer:

5 0

A linear equation of the form :

y = mx+b

can have at the most ONE x-intercept and at the most ONE y-intercept

I can conclude that this linear equation DOESN'T pass through the origin (O) and that it intercepts the x-axis as well as the y-axis

When given points (1,1) and (2,2), what is the slope ?

scoray [572]

Answer:

$m=1$

Step-by-step explanation:

Slope can be calculated using following formula

$m=\frac{y_2-y_1}{x_2-x_1}$ ----------- (1)

<u>Here</u>

$(x_1, y_1)=(1, 1) \ \ and \ \ (x_2, y_2) = (2, 2)$

Substitute values in equation (1)

$m=\frac{2-1}{2-1}$

$m=1$

A recipe requires 1/5 cup of sugar and 1/2 cup of flour. How many times as much flour is required for the recipe as sugar?

Damm [24]

Answer:

2.5 times

Step-by-step explanation:

To compare the two quantities, find a common denominator.

1/5 is 2/10 of sugar.

1/2 cup of flour is 5/10 of flour.

There is almost 3 times as much flour as sugar. 5/ 2 = 2.5. It is 2.5 times as much.

By definition, (fog)(x) = f(g(x))So if g(2) = 3 and f(3) = 16, then (fog)(2) =

marusya05 [52]

Answer:

$(f\circ g)(2)=16$

Step-by-step explanation:

By definition composite function would be:

$(f\circ g)(x)=f(g(x))$

Then, if g(2)=3 and f(3)=16, therefore for f(g(x)):

$\begin{gathered} (f\circ g)(x)=f(g(2))=f(3) \\ \text{Hence,} \\ (f\circ g)(2)=16 \end{gathered}$
