I really need help on this one too please!

The solution is: solve of the equation x²- 7x-34=10 is: x = 11 or,  x = -4.

Here, we have,

given that,

the equation is: x squared - 7x-34=10

now, we have to solve this.

so, we have,

x squared - 7x-34=10

or, x²- 7x-34=10

or, x²- 7x - 44 = 0

or,  x²- 11x + 4x - 44 = 0

or, x(x-11) + 4(x-11)

or, (x-11) (x + 4) = 0

so, we get,

either , x = 11 or, x = -4

Hence, The solution is: solve of the equation x²- 7x-34=10 is: x = 11 or,

x = -4.

Answer:

[tex]Codes= 512[/tex]

Step-by-step explanation:

Given

[tex]Switches = 9[/tex]

[tex]Controls = 2[/tex] ------- on or off

Required

Determine the number of codes to be programmed

Since each switch has any of the on or off controls (i.e on or off), then:

The first switch can be coded in any of the 2 controls

The second switch can be coded in any of the 2 controls

The third switch can be coded in any of the 2 controls

Up till the ninth switch

So, we have that:

[tex]Codes= 2 * 2 *2*2*2* 2 *2*2*2[/tex]

[tex]Codes = 2^9[/tex]

[tex]Codes= 512[/tex]

Hence, there are 512 possible codes

Step-by-step explanation:

Zaire has made par or better on 12 holes out of 15 that he has played.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

If the ratio of holes with par or better to total holes played is equal to 0.8, it means that Zaire has made par or better on 80% of the holes he has played.

Let's set up an equation to solve for the number of holes with par or better:

N/15 = 0.8

To solve for N, we can cross-multiply:

N = 15 x 0.8

N = 12

Therefore, Zaire has made par or better on 12 holes out of 15 that he has played.

Step-by-step explanation:

The length of Priya’s run was 2.5 times Tyler’s run.

Given

Priya ran 1 1/2 miles today, and Tyler ran 3 3/4 miles.

To determine how many times the length of Priya’s run was Tyler’s run following all the steps given below.

Let, the distance covered by Priya be x and Tyler be y.

Priya ran 1 1/2 miles today.

Then,

[tex]\rm = 1 \dfrac{1}{2}\times x\\\\= \dfrac{2\times 1+1}{2}\times x\\\\= \dfrac{2+1}{2}\times x\\\\=\dfrac{3x}{2}[/tex]

Tyler ran 3 3/4 miles.

[tex]\rm = 3 \dfrac{3}{4}\times y\\\\= \dfrac{4\times 3+3}{4} \times y\\\\= \dfrac{12+3}{4} \times y\\\\= \dfrac{15y}{4}[/tex]

On comparing both the distance

[tex]\rm \dfrac{3}{2} \times x= \dfrac{15}{4}\times y\\\\x = \dfrac{5y}{2} \\\\x = 2.5y[/tex]

Hence, the length of Priya’s run was 2.5 times Tyler’s run.

Answer:

20 shirts

Step-by-step explanation:

We are told she paid 80 dollars for general supplies. It costs her 2 dollars to make each t shirt.

Total cost of production is;

80 + 2t

Where t is number of t-shirts.

We are told that She charges 6 dollars per shirt.

This means that total revenue from sales is; 6t

Now,in economics or business, break even point is the point where revenue and total cost are equal.

Thus, break even point will be at;

80 + 2t = 6t

6t - 2t = 80

4t = 80

t = 80/4

t = 20 shirts
