Domain is set of all x-values. You are supposed to focus on the x-axis instead.

From the graph, the point starts from x = -5 and ends on x = 5. That means no values would exist after x = 5 or before x = -5.

Hence, the domain starts from -5 to 5.

Answer

-5≤x≤5

9966 [12]

Answer:

Step-by-step explanation:

P(A) = 4/52 = 0.07692 which is bigger than 5%

5% = 0.05

0.07 is above 5% which is surprising.

The P(Spade A) = 1/52 = 0.01923 which is under 2% which meets your criteria.

A combined total of 39000 is invested in two bonds that pay 5% and 6.5% simple interest. The annual interest is 235500 how much

dolphi86 [110]

Answer:

$12000 at 5%

$27000 at 6.5%.

Step-by-step explanation:

Let x represent amount invested at 5% and y represent amount invested at 6.5%.

We have been given that a combined total of 39000 is invested in two bonds. We can represent this information in an equation as:

$x+y=39000...(1)$

We are also told that the annual interest rate is 2355.00. We can represent this information in an equation as:

$0.05x+0.065y=2355...(2)$

Upon substituting equation (1) in equation (2), we will get:

$0.05x+0.065(39000-x)=2355$

$0.05x+2535-0.065x=2355$

$-0.015x+2535=2355$

$-0.015x=2355-2535$

$-0.015x=-180$

$\frac{-0.015x}{-0.015}=\frac{-180}{-0.015}$

$x=12000$

Therefore, an amount of $12,000 is invested at 5%.

Upon substituting $x=12000$ in equation (1), we will get:

$12000+y=39000$

$y=39000-12000$

$y=27000$

Therefore, an amount of $27,000 is invested at 6.5%.

Jinny is selling bracelets for $4.00. So far, she has earned $296.00. She needs to earn more than $472.00 in order to meet her g

Darya [45]

She needs more then 472 and has 296 so she still needs 176 because 472-296=176
Each bracelets is 4 so then 176/4 is 44
1. She needs to sell 44 more bracelets,45 if she needs more than 472
2 the inequality would be x>=44 bracelets
