Answer: 2x

Step-by-step explanation: 18+2(x-7)=4+M. First distribute 2 to (x-7), then you will be left with 18+2x-14=4+M. You can further simplify the left side of the equation by subtracting 14 from 18, now you are left with 2x+4=4+M. Subtract 4 from both sides to solve for M, 2x=M.

To find the x-intercepts of a parabola with given vertex and y-intercept, we can use the vertex form of the equation. Substituting the given values, we find the value of a, and then substitute the values again to find the x-intercepts. The x-intercepts of this parabola are approximately (0.55, 0) and (1.45, 0).

To find the x-intercepts of a parabola, we need to find the values of x when y is equal to zero. Starting with the equation of the parabola in vertex form, y = a(x-h)^2 + k, where (h,k) is the vertex, we can substitute the given values for the vertex (1,1) into the equation. This gives us y = a(x-1)^2 + 1. Next, we substitute the y-intercept (-3) into the equation, so we have -3 = a(0-1)^2 + 1. Solving for a, we get a = -2.

Now we can substitute a and the given values into the equation again to find the x-intercepts. Plugging in a = -2, we have 0 = -2(x-1)^2 + 1. Simplifying this equation and solving for x, we get x = 1 ± √(3/2). Rounding to the nearest hundredth, the x-intercepts are approximately (0.55, 0) and (1.45, 0).

Step-by-step explanation:

Givens

Let Phoebe = P

Let Andy = A

Let Polly = Po

Total = 270

Equations

P = 3*A

A = 2*Po

P + A + Po = 270

Solution

P + 2Po + Po = 270

P = 3*A                                       But A = 2Po. Substitue 2Po for A

P = 3(2*Po)                                 Combine the right

P = 6Po                                      Substitute 6Po for P  

6Po + 2Po + Po = 270               Combine the left

9*Po = 270                                 Divide by 9

9Po/9 = 270/9                           Do the division

Po = 30

Answer:

[tex]a=0.1\\b=0.85[/tex]

Step-by-step explanation:

In this problem we are calculating the relative frequency conditional by columns.

Therefore the sum of the frequencies of each column must be equal to 1.

Then we use this condition to calculate the values of a and b

So:

[tex]0.9 + a = 1\\a = 1-0.9\\a = 0.1[/tex]

[tex]b +0.15 = 1\\b = 1-0.15\\b = 0.85[/tex]

Finally

[tex]a=0.1\\b=0.85[/tex]

Answer:

Values of a and b are:

a=0.1

and b=0.85

Step-by-step explanation:

As we can clearly see from the table that sum of each column is equal to 1.0

i.e. 0.9+a=1.0

and b+0.15=1.0

Hence, a=1.0-0.9

              = 0.1

and b=1.0-0.15

        =0.85

Hence, Values of a and b are:

a=0.1

and b=0.85

Answer:

x=6

x=2

Step-by-step explanation:

Fortunately for us, the function is written in factorized terms, so it is easier to find its roots.

The roots are the values for the 'x' variables that makes the functions goes to zero.

They are x=6 and x=2, any of those value make the function equals zero, or in other words, they are the points of interception with the 'y' axis.

To obtain these value

lets study the following condition

(x-6) * (x-2)=0

The above is accomplish when (x-6)=0 or (x-2)=0

We have two independent equations from where we obtain that x=6 and x=2

Answer:

y = 4x + b, where b is any number

Step-by-step explanation:

Adrian, you need to share the possible answer choices.

Every line parallel to y = 4x + 1 has the slope 4.

This is true for any y-intercept, that is, for any b in y = mx + b.

Final answer:

An equation of a line parallel to y=4x+1 would have the same slope of 4 and can be expressed as y=4x+b, where b is any y-intercept not equal to 1.

Explanation:

An equation of a line parallel to the line represented by y=4x+1 would have the same slope as the given equation. This is because parallel lines have identical slopes. In the equation y=4x+1, the slope is 4, as this is the coefficient of x. Therefore, any line that has a slope of 4 will be parallel to y=4x+1. The general form for such a parallel line would be y=4x+b, where b is the y-intercept, which can be any number different than 1 to ensure the lines are not the same.

Answer:

Segment JK is a chord in circle H

Line LM is a secant to circle H

Step-by-step explanation:

* Lets revise some definition in the circle

- The radius of the circle is a line segment drawn from the center of  

 the circle to a point on the circumference of the circle

- The chord of a circle is a line segment whose endpoints lie on the

 circumference of the circle

- The secant is a line intersect the circle in two points

- The tangent is a line touch or intersect the circle in one point

* Now lets solve the problem

- In circle H

∵ JK is a segment in circle H

∵ Point J lies on the circumference of circle H

∵ Point K lies on the circumference of circle H

∴ Segment JK is a chord in circle H

∵ LM is a line

∵ LM intersect circle H in two points L and M

∴ Line LM is a secant to circle H

Answer:

It is f(x) = -x^2 + 2x + 4.

Step-by-step explanation:

As it has a maximum the coefficents of x^2 will be negative.

f(x) = -x^2 + 2x + 4

The y-intercept occurs when x = 0 so

y-intercept = 0 + 0 + 4 = 4.

-

ANSWER

[tex]f(x) = - {x}^{2} + 2x + 4[/tex]

EXPLANATION

The graph of the function that will have a maximum and a y-intercept of 4 is

[tex]f(x) = - {x}^{2} + 2x + 4[/tex]

To check for the y-intercept, we put x=0 into the function.

[tex]f(0) = - {0}^{2} + 2(0)+ 4[/tex]

This implies that,

[tex]f(0) = 4[/tex]

We can see that the coefficient of the quadratic term is -1.

Since the coefficient of the quadratic term is less than zero, the graph will have a maximum point.

Answer:

- Discontinuity at (-1,6)

 - The zero is at (-7,0)

Step-by-step explanation:

Given the function [tex]f(x)=\frac{x^2 + 8x + 7}{x+1}[/tex], you need to factor the numerator. Find two number whose sum be 8 and whose product be 7. These are 1 and 7, then:

[tex]f(x)=\frac{(x+1)(x+7)}{(x+1)}[/tex]

Then, the denominator is zero when [tex]x=-1[/tex]

Therefore, [tex]x=-1[/tex] does not belong to the Domain of the function. Then, (-1,6) is a discontinuity point.

Simplifying, you get:

[tex]f(x)=x+7[/tex]

You can observe that a linear function is obtained.

This function is  equal to zero when [tex]x=-7[/tex], therefore the zero of the function is at (-7,0).

ANSWER

Discontinuity:

[tex]x = - 1[/tex]

Zero:

[tex]x = - 7[/tex]

EXPLANATION

The given rational function is

[tex]f(x) = \frac{ {x}^{2} + 8x + 7 }{x + 1} [/tex]

We factor function to obtain:

[tex]f(x) = \frac{(x + 1)(x + 7)}{x + 1} [/tex]

This function is not continuous when

[tex](x + 1) = 0[/tex]

The function is not continuous at

[tex]x = - 1[/tex]

When we simplify the function, we get;

[tex]f(x) = x + 7[/tex]

The zero(s) occur at

[tex]x + 7 = 0[/tex]

[tex]x = - 7[/tex]

Answer:

3:2

Step-by-step explanation:

To answer questions like this I would makeup an age for Alan

Like say Alan is 10 years old

John is 3 times the age of 10 so he is 30

Ralph is twice the age of 10 so he is 20

so 30/20 can be simplified to 3/2

There are other ways to solve it but that is how I would solve it

I hope it helped you

Answer:

3:2 or 3/2

Step-by-step explanation:

Let Alan's age be x

So according to the assumed variable, John's age will be three times of Alan's age

John's Age = 3x

Similarly,

Twice of Alan's age = 2x

so, Ralph's age = 2x

Since we have to find the ratio of John's age to Ralph's age that will be equal to

3x : 2x

which can also be written as:

3:2 or 3/2 ..

Answer:

f(x)=-1(x+4)(x-3)

or  f(x)=-(x+4)(x-3)

Step-by-step explanation:

We see zeros at x=-4 and x=3.

So the factors are (x+4) and (x-3).

So we have a function that looks like

f(x)=A(x+4)(x-3).

y=A(x+4)(x-3)

I see the point (1,10) is on the curve.

So that means

10=A(1+4)(1-3)

10=A(5)(-2)

10=A(-10)

A=-1

So the function is f(x)=-1(x+4)(x-3)

or                          f(x)=-(x+4)(x-3)

Answer:

The height of the trapezoid is [tex]4.5\ ft[/tex]

Step-by-step explanation:

we know that

The area of a trapezoid is equal to

[tex]A=\frac{1}{2}(b1+b2)h[/tex]

In this problem we have

[tex]A=33.75\ ft^{2}[/tex]

[tex]b1=5\ ft[/tex]

[tex]b2=10\ ft[/tex]

substitute in the formula and solve for h

[tex]33.75=\frac{1}{2}(5+10)h[/tex]

[tex]67.5=15h[/tex]

[tex]h=67.5/15=4.5\ ft[/tex]

Answer:

[tex]h=4.5\text{ feet}[/tex]

Step-by-step explanation:

We have been given that a plot of land has an area 33.75 square feet. Jackson wants to put a 4-foot by 4 foot shed on the land. Jackson wants to put a 4-foot by 4 foot shed on the land. He can only do this if the height of the trapezoid is at least 4.5 feet.

We will use area of trapezoid to find the height of trapezoid.

[tex]\text{Area of trapezoid}=\frac{1}{2}(a_1+a_2)\times h[/tex], where,

[tex]a_1\text{ and }a_2=\text{ Parallel sides or bases of trapezoid}[/tex],

[tex]h=\text{Height}[/tex].

We can see that parallel sides are 5 feet and 10 feet. We have been given that area of trapezoid is 33.75 square feet.

[tex]33.75\text{ feet}^2=\frac{1}{2}(\text{ 5 feet + 10 feet})\times h[/tex]

[tex]33.75\text{ feet}^2=\frac{1}{2}(\text{ 15 feet})\times h[/tex]

Switch sides:

[tex]2\times\frac{1}{2}(\text{ 15 feet})\times h=2\times 33.75\text{ feet}^2[/tex]

[tex]\text{ 15 feet}\times h=67.50\text{ feet}^2[/tex]

[tex]\frac{\text{ 15 feet}\times h}{\text{ 15 feet}}=\frac{67.50\text{ feet}^2}{\text{ 15 feet}}[/tex]

[tex]h=4.5\text{ feet}[/tex]

Since the height of trapezoid is 4.5 feet, therefore, Jackson can put a 4 foot by 4 foot shed on the land.

Answer:  THIRD OPTION.

Step-by-step explanation:

We need to remember that we can create a perfect square trinomial by squaring a binomial:

[tex](a\±b)^2=a^2\±2ab+b^2[/tex]

Then we need need to pick the coefficient of the x term of the given expression, divide it by 2 and square it:

[tex](\frac{3}{2})^2=\frac{9}{4}[/tex]

Therefore, the number that should be added to the given expression  in order to create a perfect square trinomial is:

[tex]\frac{9}{4}[/tex]

To solve this you must use a proportion like so...

[tex]\frac{part}{whole} = \frac{part}{whole}[/tex]

65 is a percent and percents are always taken out of the 100. This means that one proportion will have 65 as the part and 100 as the whole

We want to know out of what number is 78 65%. This means 78 is the part and the unknown (let's make this x) is the whole

[tex]\frac{78}{x} =\frac{65}{100}[/tex]

Now you must cross multiply

78*100 = 65*x

7800 = 65x

To isolate x divide 65 to both sides

7800/65 = 65x/65

120 = x

This means that 65% of 120 is 78

Then the piece is cut into two pieces.

Let's call x the length of the first piece  of cable and call z the length of the second piece of cable.

So we know that

[tex]x + z = 136[/tex]

and

[tex]x = 3z-16[/tex]
