35x^2-27x-18 = (7x - 9)(5x +2)

F(x) = 1/2x^2 is a variation of the basic graph y = x^2 (the squaring function).

The graph of the squaring function has the shape of a parabola that opens up.  Its vertex is at (0,0).

The graph of F(x) = (1/2)x^2 has the same shape, but is compressed vertically by a factor of (1/2).   The vertex of F(x) = (1/2)x^2 is still (0,0).  That eliminates the first 2 possible answers.  Note that F(1) = (1/2)(1)^2 = 1/2.  The point (1, 1/2) is on the third graph, but not on the fourth.  Thus, the third graph is correct.

Only the third graph (option C) represents the graph of [tex]F(x) = \frac{1}{2} x^2[/tex]

The given function is:

[tex]F(x) = \frac{1}{2} x^2[/tex]

This graph is of the form [tex]y = ax^2[/tex] and it takes the shape of a parabola with center at (0, 0)

Only two of the graphs shown among the options have the center at the origin (0, 0), but only one is scaled by 0.5

I only get one (2, 11)

to find the points which are solutions, substitute the x-coordinate into the equation and if the value obtained equals the y-coordinate of the point then it is a solution

(7, 16) : y = (3 × 7 ) + 5 = 21 + 5 = 26 ≠ 16

( - 2, 1): y = (3 × - 2) + 5 = - 6 + 5 = - 1 ≠ 1

(2, 11) : y = (2 × 3) + 5 = 6 + 5 = 11

( - 7,16 ): y = (3 × - 7) + 5 = - 21 + 5 = - 16 ≠ 16

[tex]\sqrt{63} = \sqrt{9*7} = \sqrt{3*3*7}  = 3\sqrt{7}[/tex]

The simplified form of √(63) after removing all perfect squares from inside the square root is 3√(7).

To simplify the square root of 63 and remove perfect squares, we start by finding the prime factorization of 63. The prime factorization of 63 can be obtained by dividing the number by its smallest prime factor, which is 3, and then continuing the process for each quotient until we get a prime number. The prime factorization of 63 is:

63 = 3 * 3 * 7.

Now, we look for any perfect square factors within the square root of 63. In this case, the perfect square factor is 3 * 3 (3 squared). We can remove this perfect square from the square root, leaving us with:

√(63) = √(3 * 3 * 7).

Since we removed one pair of 3's (3 * 3), the simplified square root of 63 becomes:

√(63) = 3√(7).

Answer:

c = 3 oil changes

Step-by-step explanation:

The fixed rate for oil change is $ 40

The surplus rate for miles outside the radius is $ 2.25

Josh lives 7 miles of the radius

Therefore an equation for c: The largest number of oil changes that can be scheduled and maintained within the budget for the year is:

[tex]\\40c + 2.25 * 7c = 200\\c (40 + 2.25 * 7) = 200\\c =\frac{200}{40 + 2.25 * 7}\\c = 3,578\\c = 3[/tex] oil changes

Therefore, with the budget set Josh can make a maximum of 3 oil changes per year

Answer:

The answer is 3

Step-by-step explanation

mileage fee for each oil change: 7(2.25) = $15.75

service call + mileage fee = total for each oil change

$40 + $15.75 = $55.75

c = number of oil changes

55.75c = total amount for all oil changes

55.75c ≤ 200

c ≤ 3.59

Therefore, the greatest number of oil changes that Josh can schedule without exceeding his budget is 3.

Answer:

Option C

Step-by-step explanation:

given two equations

6m-5n= 14   ... i

2m+2n= -10  ...ii

We can solve this by elimination.

For elimination consider the coefficients of m.

They are 6 and 2, with LCD 6

You multiply 2nd equation by 3 to have

6m+6n =-30 ... iii and

6m-5n  = 14  ... i

Subtract i from iii

11n = -44

Divide by 11 to get n

n = -4

Substitute in I equation

6m-5(-4) =14

6m +20 = 14

subtract 20

6m =14-20 =-6

divide by 6

m =-1

Hence answer is m=-1 and n=-4

Option C is the answer.

Answer:

[tex]r(x)=(4x)^7[/tex]

Step-by-step explanation:

For example,

If we wanted to horizontally compress [tex]y=x^2[/tex], we would multiply by 4 to get [tex]y=(4x)^2[/tex], and

if we wante to horizontally expand [tex]y=x^2[/tex], we would multiply by [tex]\frac{1}{4}[/tex] to get [tex]y=(\frac{1}{4}x)^2[/tex]

Since this question asks for horizontal compression, we multiply the [tex]x[/tex] of the function by 4. So the function we need is [tex]f(x)=(4x)^7[/tex]. The second choice is correct.

[tex]f(x)=3x+5,\ g(x)=-2x^2-5x+3\\\\(f+g)(x)=f(x)+g(x)=(3x+5)+(-2x^2-5x+3)\\\\=3x+5-2x^2-5x+3=-2x^2+(3x-5x)+(5+3)=-2x^2-2x+8\to\boxed{C.}[/tex]

Answer:

You need annual gross pay of 20000.

Step-by-step explanation:

Suppose, your annual gross pay is  [tex]x[/tex]

You estimate that the net pay will be 65% of your gross pay. So, the annual net pay will be:  [tex]x*65\% = 0.65x[/tex]

As there are 52 weeks in 1 year, so your weekly net pay will be:  [tex]\frac{0.65x}{52}[/tex]

Given that, you will need 250 per week after taxes to get by. So, the equation will be......

[tex]\frac{0.65x}{52}=250\\ \\ 0.65x= 52*250=13000\\ \\ x=\frac{13000}{0.65}=20000[/tex]

So, you need annual gross pay of 20000.

First we have to change 7 1/5 into an improper fraction. 7 1/5 converted to an improper fraction is 36/5. Now, to divide this by 1/8, we need to multiply it by 8 (multiplying by the reciprocal). 36/5 * 8/1 = 288/5. In simplest form, this is 57 3/5.

The division problem 7 1/5 divided by 1/8 is solved by converting the mixed number to an improper fraction, converting the division problem to a multiplication problem by multiplying by the reciprocal, and then simplifying the resulting fraction. The final answer is 57.6.

To solve the problem 7 1/5 divided by 1/8, we first need to convert the mixed number 7 1/5 into an improper fraction. We do this by multiplying the whole number 7 by the denominator of the fraction 5 and then adding the numerator 1. So, 7 * 5 + 1 = 36.

So, 7 1/5 becomes 36/5. Now, we have 36/5 divided by 1/8.

When we are dividing by a fraction, we need to multiply by its reciprocal. The reciprocal of 1/8 is 8/1. So the problem becomes 36/5 multiplied by 8/1.

When multiplying fractions, we simply multiply the numerators and the denominators together. So, 36 * 8 = 288 and

5 * 1 = 5. Therefore, our answer is 288/5. Lastly, when we simplify this, it becomes 57.6.

Add 4 to both sides of the equation:

[tex]x^2+4x=4[/tex]

Add half the coefficient of [tex]x[/tex] to both sides of the equation.

[tex]x^2+4x+(2)^2=4+(2)^2[/tex]

The Left Hand Side of the equation is now a perfect square.

[tex](x+2)^2=4+4[/tex]

[tex](x+2)^2=8[/tex]

Take the square root of both sides

[tex]x+2=\pm \sqrt{8}[/tex]

[tex]x=-2\pm 2\sqrt{2}[/tex]

Hence the correct answer is option C

Given equation is [tex]x^2+4x-4=0[/tex]

we get: a=1, b=4, c=-4

plug these values into quadratic formula:

[tex]x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]x=\frac{-4 \pm \sqrt{4^2-4(1)(-4)}}{2(1)}[/tex]

[tex]x=\frac{-4 \pm \sqrt{16-4(-4)}}{2}[/tex]

[tex]x=\frac{-4 \pm \sqrt{16+16}}{2}[/tex]

[tex]x=\frac{-4 \pm \sqrt{32}}{2}[/tex]
