Franco scored 9 3/5 in a gymnastics cam petition. Which point on the number line represents his score.

Answer:

[tex]H'(-3,-18)\\\\J'(3,-9)\\\\K'(-15,-3)\\\\L'(15,-15)[/tex]

Step-by-step explanation:

We know the coordinates of the polygon HJKL:

H(-1,-6), J(1,-3), K(-5,-1), and L(5,-5)

We know that the polygon HJKL is dilated using the scale factor 3. This means that, to find the coordinates of the vertices of polygon H'J'K'L', we need to multiply the x-coordinate and the y-coordinate of each vertex by this scale factor.

Then:

[tex]H'=(-1(3),-6(3))=(-3,-18)\\\\J'=(1(3),-3(3))=(3,-9)\\\\K'=(-5(3),-1(3))=(-15,-3)\\\\L'=(5(3),-5(3))=(15,-15)[/tex]

Divide the numerator by the denominator to get a decimal. Then move the decimal 2 places to the right and add the percent sign.

Answer:

-¼ = Slope

[0, 2] = y-intercept

y = -¼x + 2

Step-by-step explanation:

Your y-intercept is [0, 2] and your x-intercept is [8, 0] (not all the time your x-intercepts will be endpoints)]. Simply do rise\run until you hit another endpoint, starting from your y-intercept. As you can see, you go two blocks south, then eight blocks over east, since in this case, you are moving by increments of 2. If you were to recreate this graph in increments of 1, you would see that the simplification of -2\8, is -¼. That is why the rate of change is -¼. Do you understand?

Step-by-step explanation:

x(2x + 4x² - 5 – 3x)

1. Distribute the x

2x² + 4x³ - 5x - 3x²

2. Combine like terms

4x³ - 5x – x²

3. Write the expression in order of descending powers of x

[tex]\boxed{\mathbf{4x^{3} - x^{2} - 5x}}[/tex]

Step-by-step explanation:

Given the system of equations:

[tex]\left \{ {{y=\frac{4}{5}x-3 } \atop {y=-7}} \right.[/tex]

You can apply the Substitution method.

You need to substitute the second equation which gives the value of the variable "y" into the first equation and solve for the variable "x", then:

[tex]y=\frac{4}{5}x-3\\\\-7=\frac{4}{5}x-3\\\\-7+3=\frac{4}{5}x\\\\-4=\frac{4}{5}x\\\\(-4)(5)=4x\\\\x=\frac{-20}{4}\\\\x=-5[/tex]

Answer:

(x+7) is not a factor

Step-by-step explanation:

we know that

If (x+7) is a factor of f(x)

then

For [tex]x=-7, f(-7)=0[/tex]

Verify

we have

[tex]f(x)=x^{3}-3x^{2} +2x-8[/tex]

Substitute x=-7

[tex]f(-7)=(-7)^{3}-3(-7)^{2} +2(-7)-8[/tex]

[tex]f(-7)=-343-147 -14-8[/tex]

[tex]f(-7)=--512[/tex]

[tex]-512\neq 0[/tex]

therefore

(x+7) is not a factor

Answer:

12

Step-by-step explanation:

g(1.5) is 8 - 3(1.5), or 8 - 4.5, or 3.5.

Then substitiute 3.5 for x in h(x) = 2x + 5:  h(g(1.5)) = h(3.5) = 7 + 5 = 12

Your question asks what the value of h(g(1.5)) is.

To find the answer to your question, we're going to need to solve g(x) first, then plug in the answer from g(x) to h(x).

Lets solve:

We're going to plug in 1.5 to our "x" variables in the g(x) equation.

Your equation should look like this:

[tex]g(x)=8-3(1.5)[/tex]

Now, you solve:

[tex]g(x)=8-3(1.5)\\\\g(x)=8-4.5\\\\g(x)=3.5[/tex]

You should get 3.5

Once you're done solving g(x), we would plug in the answer we got from the G(x) equation into our h(x) equation.

Your equation should look like this:

[tex]h(x)=2(3.5) + 5[/tex]

Then, you solve:

[tex]h(x)=2(3.5) + 5\\\\h(x)=7+5\\\\h(x)=12[/tex]

Once you're done solving, you should get 12

This means that the value of h(g(1.5)) is 12.

12 should be your FINAL answer.

Let the number of hours driven equal x.

You would multiply the number of hours by his speed, so you would have 50x

You would then want to subtract that from the total miles to see how many more miles he needs to drive.

The answer would be E. y = 470 - 50x

Answer:

The distance between both points would be 14.

Step-by-step explanation:

The y coordinate or -8 stays the same for both points on a coordinate grid. However the x coordinate changes from -4 to 10, which is 14 places away on a coordinate grid. Therefore the distance between these two points is 14.

Answer:

14

Step-by-step explanation:

Use the distance equation:

d² = (x₂ − x₁)² + (y₂ − y₁)²

d² = (10 − -4)² + (-8 − -8)²

d² = 14² + 0²

d = 14

Answer:

[tex]{\huge \boxed{X<-2}}[/tex]

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

Expand.

4(1-3x)-14=-12x-10

4(2x+3)-9x=-x+12

-12x-10>-x+12

Add by 10 from both sides of equation.

-12x-10+10>-x+12+10

Simplify.

-12x>-x+22

Add by x from both sides of equation.

-12x+x>-x+22+x

Simplify.

-11x>22

Multiply by -1 from both sides of equation.

(-11x)(-1)<22(-1)

Simplify.

11x<-22

Divide by 11 from both sides of equation.

11x/11<-22/11

Simplify, to find the answer.

-22/11=-2

x<-2 is the correct answer.

I hope this helps you, and have a wonderful day!

Answer: A is correct (x+2)/(x-1)

Step-by-step explanation:

Divide the top and bottom by 2, to simplify

[2(x^2+x-2)]/[2(x^2+2x+1)]

The 2's cancel each other out, since 2/2 would be 1.

Now factor (x^2+x-2)/(x^2+2x+1)

[(x+2)(x-1)]/[(x-1)(x-1)]

Now you can cancel out one of the (x-1) on top and bottom. All that's left is (x+2)/(x-1) which is your answer. Hope this helps!

Answer:

[tex]f(x) = (4\sqrt{5})^{x}[/tex]

Step-by-step explanation:

The exponential function looks like the following: [tex]f(x) = b^{x}[/tex].

If the function passes through the point (2, 80), then:

[tex]f(x) = b^{x}[/tex] → [tex]80 = b^{2}[/tex]

Solving for 'b':

[tex]b = \sqrt{80}[/tex] →[tex]b=4\sqrt{5}[/tex]

Then, the equation of exponential function that passes through the point (2, 80) is: [tex]f(x) = (4\sqrt{5})^{x}[/tex]

Answer:

A.

Only function g is even

Option: A is the correct answer.

  A.   Only function g is even.

Here by looking at the graph we observe that the graph of function g satisfies the condition of even function.

( whereas the graph of function f is not symmetric about the y-axis and hence function f is not even )

     Hence,  the function g is an even function.

Answer:

6 units

Step-by-step explanation:

We require to calculate the absolute value so as to consider the measure both ways, that is

AB = | 1 - (- 5) | = | 1 + 5 | = 6

BA = | - 5 - 1 | = | - 6 | = 6

Reading from top to bottom. Answers are as follows:

1. 7(2)^t

2. 3000(0.93)^t

3. 300(1.015)^t

4. 300(0.985)^t

We know that the exponential function is given by:

             [tex]f(x)=ab^x[/tex]

where a is the initial amount.

and b is the change in the amount and is given by:

[tex]b=1+r[/tex] if the function is increasing by a rate of r

and [tex]b=1-r[/tex] if the function is decreasing by a rate of r.

a)

The initial amount of fish in the trout are: 7

i.e. a=7

Also, the population doubles every year.

This means that that b=2

Hence, the population after t years is given by the function P(t) as:

[tex]P(t)=7(2)^t[/tex]

b)

The original amount of the machine is: $ 3,000

i.e. a=3,000

Also, the value of machine decreases by a rate of 7%

i.e.

[tex]r=7\%\\\\i.e.\\\\r=0.07[/tex]

Hence, we have:

[tex]b=1-r\\\\i.e\\\\b=1-0.07\\\\i.e.\\\\b=0.93[/tex]

Hence, the function which represent the price of the machine after t years i.e. P(t) is given by:

[tex]P(t)=3000(0.93)^t[/tex]

c)

The initial population of colony of ants i.e. a=300.

The number of ants increases at a rate of 1.5% every month.

i.e. [tex]r=1.5%\\\\i.e.\\\\r=0.015[/tex]

i.e.

[tex]b=1+r\\\\i.e.\\\\b=1+0.015\\\\i.e.\\\\b=1.015[/tex]

Hence, the function P(t) which represents the population of ants after t months is given by:

[tex]P(t)=300(1.015)^t[/tex]

d)

The initial infected cells i.e. a=300

The infected cells are decaying at a rate of 1.5% per minute.

i.e.

[tex]r=1.5%\\\\i.e.\\\\r=0.015[/tex]

Since, there is a decay hence,

[tex]b=1-r\\\\i.e.\\\\b=1-0.015\\\\i.e.\\\\b=0.985[/tex]

Hence, the function P(t) which represents the number of infected cells after t minutes is given by:

[tex]P(t)=300(0.985)^t[/tex]

For this case we have that a quadratic equation is of the form:[tex]ax ^ 2 + bx + c = 0[/tex]

Where:

a: is the main coefficient because it accompanies the quadratic variable.

b: It is the linear coefficient

c: It is the constant term.

Then, a quadratic function with a main coefficient of "3" and a constant term of "-12" is:

[tex]f (x) = 3x ^ 2 + 11x-12[/tex]

Answer:

Option B

[tex]f (x) = 3x ^ 2 + 11x-12[/tex]

Answer:

If this question is on Edg, then it is B, & B is Correct.

Answer:

y+5 = -3(x-1)  point slope form

y = -3x-2 slope intercept form

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/ (x2-x1)

m = (7--5)/(-3-1)

   = (7+5)/(-3-1)

   = 12/-4

   = -3

The slope is -3

Then we can use point slope form to write an equation

y-y1 = m(x-x1)

y--5 = -3(x-1)

y+5 = -3(x-1)

This is in point slope form

Distribute

y+5 = -3x+3

Subtract 5 from each side

y+5-5 = -3x +3-5

y = -3x-2

This is in slope intercept form

Answer:

A

Step-by-step explanation:

A function maps one member in the domain ( x values ) to exactly one member in the range (y values ).

A is the only diagram representing this characteristic.

first off, we know the angles at vertices C and F are right-angles, meaning both triangles are right-triangles.

we also know that sides AC = DF and BC = EF.

now, for right-triangles, if the two shorter legs are congruent in both triangles, the triangles are congruent by the Leg Leg theorem, namely LL.
