Answer:

B) 60

Step-by-step explanation:

<u>Given:</u>

<A = 2x
<B = 60
<A and <B are supplementary angles (they add up to 180)

<u>Equation:</u>

<A + <B = 180

2x + 60 = 180

2x = 180 - 60

2x = 120

x = 60

When Brad was born, his Grandma put, $1,500 in a new account for him. Since then, the balance of the account, has grown by 6.5%

marin [14]

Answer:

$969.04

Step-by-step explanation:

now at age of 18 Brad has 1500 * 1,065^18

at age of 21 he will have 1500 * 1,065^21

if he waits the difference will be 1500 * 1,065^21 - 1500 * 1,065^18 = $969.04

write a linear equation that intersects y=x^2 at two points. Then write a second linear equation that intersects y=x^2 at just o

Liula [17]

We know that $y = x^2$ is a parabola, concave up, with vertex in the origin $(0,0)$

So, we may use three horizontal lines for our purpose: any horizontal line above the x axis will intersect the parabola twice. The x axis itself intersects the parabola once on the vertex, while any horizontal line below the x axis won't intercept the parabola.

Here's the examples:

The horizontal line $y = 4$ intercepts the parabola twice: the system $y = x^2,\ y = 4$ is solved by $x^2=4 \implies x = \pm 2$
The horizontal line $y=0$ intercepts the parabola only once: the system is $y=x^2,\ y=0$ which yields $x^2=0\implies x=0$ which is a repeated solution
The horizontal line $y=-5$ intercepts the parabola only once: the system is $y=x^2,\ y=-5$ which yields $x^2=-5$ which is impossible, because a squared number can't be negative.

A craft store has 5 yards and 2 inches of ribbon. The cost of the ribbon is calculated per inch. How many inches of

suter [353]

Answer:

182

Step-by-step explanation:

5 yards = 5*3 = 15 feet

15 feet = 15 * 12 = 180 inches.

There are 2 more inches in the ribbon. 180 + 2 = 182 inches.
