Answer:

y-intercept- (0,-5)

 x-intercept  ( 1 , 0 ) , ( − [tex]\frac{5}{3}[/tex] ,0)

Step-by-step explanation:

y-intercept- (0,-5)

 x-intercept  ( 1 , 0 ) , ( − [tex]\frac{5}{3}[/tex] ,0)

Answer:

If by 3x2 you meant 3(2), then the y-intercept is 1.

Step-by-step explanation:

We need to start by simplifying the equation.

y = 3(2) + 2x - 5

y = 6 + 2x - 5

y = 2x + 6 - 5

y = 2x + 1

The "2x" part tells us the growth rate, or slope, of the line, and the "+ 1" is the y-intercept.

Answer:

(2, -3), (3, -3)

Step-by-step explanation:

y = x^2 - 5x + 3

y = -3

x^2 - 5x + 3 = -3

x^2 - 5x + 6 = 0

(x - 3)(x - 2) = 0

x - 3 = 0 or x - 2 = 0

x = 3 or x = 2

We are given y = -3.

Answer: (2, -3), (3, -3)

Answer:

(2, -3) , (3, -3)

Step-by-step explanation:

One is asked to find what values of the parameter (x) will yield the result (f(x)=-3) if the function (f(x)) is the following,

[tex]f(x)=x^2-5x+3[/tex]

Set this equation up, and solve to find the value of (x) that satisfies this requirement:

[tex]f(x)=x^2-5x+3=-3[/tex]

Inverse operations,

[tex]x^2-5x+6=0[/tex]

Factor, rewrite the quadratic equation as the product of two linear equations,

[tex](x-2)(x-3)=0[/tex]

Therefore the solutions are the following, the (x-coordinate) represents the input, and the (y-coordinate) represents the output.

(2, -3), (3, -3)

Answer:

1/45

Step-by-step explanation:

P(Y,Y) = 2/10 x 1/9

= 1/45

Answer: Step-by-step explanation:

57 - 10x = 45

-10x=-12

x=1.2

- 3y + 10x = -5

-3y+10=-5

-3y=-15

y=5

Answer:

1) 57 - 10x = 45 answer: x=−51/5

2) - 3y + 10x = -5 answer: x=3/10y+−1/2 or y=10/3x+5/3

Step-by-step explanation: Hope this help :D

Answer:

a=12

Step-by-step explanation:

We must use SOH, CAH, TOA

SOH= Sin0=opp/hyp

CAH=Cos0=adj/hyp

TOA= Tan0=opp/adj

Since we have opposite and hypotenuse we use Sin ratio, in this case,

sin30°= [tex]\frac{a}{24}[/tex]

[tex]\frac{1}{2}[/tex]=[tex]\frac{a}{24}[/tex] we cross multiply

[tex]\frac{2a}{2}[/tex]=[tex]\frac{24}{2}[/tex]divide both sides by 2 to get a by itself

a=12

Answer:

a = 12

Step-by-step explanation:

To find a, we will use the trigonometric ratio of Sin, since the opposite side of the angle given needs to be found out and the hypotenuse is given;

Sin(30) = [tex]\frac{a}{24}[/tex]

Sin(30) * 24 = a

12 = a

Answer:

324/540 cats and dogs should be expected to be given away

Step-by-step explanation:

First, write the fraction of the cats on the spinner plus the dogs on the spinner.

[tex]\frac{4}{10} + \frac{2}{10} = \frac{6}{10}[/tex]

Now, we have to make the denominator 540 but we have to make it equal so you divide.

540 ÷ 10 = 54

So, our fraction should look like this.

[tex]\frac{x}{540}[/tex]

Now, multiply 6 × 54 = 324

[tex]\frac{324}{540}[/tex] is our answer

Have a great day!

The dog or cat toys are expected to be given away = 378

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.

If the spinner is spun 540 times throughout the day.

Total fraction of the cat and dogs together,

= 5/10+2/10

=7/10

Divide the 540 into 10 equal parts,

= 540/10

=54

let 'x' dog or cat toys are expected to be given away

So, x/540 = 7/10

x= 54*7

x= 378.

Hence, dog or cat toys are expected to be given away = 378/540
