Step-by-step explanation:

From the question we are told that:

Parabola  focus co-ordinates

[tex]F=(-4, -5)\\Directrix is y = -1[/tex]

Generally the equation for standard form of Parabola is mathematically given by

[tex](x - h)^2 = 4p(y - k)[/tex]

where p≠ 0

Generally the equation for Directrix of Parabola is mathematically given by

[tex]y=k-p\\y=-1[/tex]

Generally the equation for Focus of Parabola F is mathematically given by

[tex]F=(h, k + p).[/tex]

[tex]F=(-4, -5)[/tex]

Therefore

[tex]k-p=-1[/tex]

[tex]k=-1+p[/tex]

Given

[tex]k+p=-5[/tex]

[tex]-1+p+p=-5[/tex]

[tex]2p=-4[/tex]

[tex]p=-2[/tex]

Therefore

[tex]k-p=-1[/tex]

[tex]k-(-2)=-1[/tex]

[tex]k=-3[/tex]

Generally the equation for standard form of Parabola is mathematically given by

[tex](x - (-4))^2 = 4(-2)(y - (-3))[/tex]

[tex](x - (-4))^2 = -8(y - (-3))[/tex]

[tex]Where p<0[/tex]

Answer:

No, 5 isn't a solution to 7x - 4 + x = 12

Step-by-step explanation:

7x - 4 + x = 12

combine common x-values

8x - 4 = 12

add

8x = 16

solve for x

x = 2

Answer:

No, 5 is not the solution...

Step-by-step explanation:

7x-4+x=12

7x+x=12+4

Answer:

2x - 7y = -34.

Step-by-step explanation:

As the line we want is perpendicular to y= -7/2 x + 9 it's slope will be

-1 /(-7/2) = 2/7.

Now we find the point of intersection ofn the 2 given  lines:

x    + y = 10

3x - 4y = -12

Multiply the first equation by -3:

-3x - 3y = -30

Now add this last equation to the second one:

-7y =  -42

y = 6

Plug y = 6 into the first equation:

x + 6 = 10

x = 4.

So the point of intersection is (4, 6) and the equation we want passes through this, so using the point-slope form of  straight line we have:

y - 6 = 2/7(x - 4)

7y - 42 = 2(x - 4)

7y - 42 = 2x - 8

2x - 7y = -42 + 8

2x - 7y = -34

Answer:

y=(2/7)x+(7/3)

Step-by-step explanation:

y=-7/2(x)+9

y=mx+c

Therefore, slope of line y is -7/2

Because line y perpendicular to the required line

Therefore, slope of the required line is 2/7

x+y=10 ........(1)

3x-4y = -12 ......(2)

(1) x 4:

4x+4y =40 ......(3)

(3) + (2)

4x+4y+3x-4y=28

x=4

by substituting x=4 into (1), we have

y=10-4=6

Therefore, the point that the line intersects is (4, 6)

let y=(2/7)x+c be the required equation

(4, 6):

6=(2/7)4+c

c=21/4

therefore, the required equation is y=(2/7)x+(7/3).

How to know if the side lengths can form a triangle:

Add together two of the lowest numbers. If it is greater than the largest number, it can form a triangle.

13. Yes, these side lengths can form a triangle.

-- 4 + 5 = 9.

-- 9 is greater than 7, the largest length.

14. No, these side lengths can't form a triangle.

-- 2 + 3 = 6

-- 6 is equal to 6, not greater than.

15. Yes, these side lengths can form a triangle.

-- 2 + 4 = 6

-- 6 is greater than 5, the largest number.

16. Yes, these side lengths can form a triangle.

-- Don't get confused when you see that there are two side lengths that are the same (it means that this is an isosceles triangle); the rules still apply.

-- 2 + 8 = 10

-- 10 is greater than 8, the largest number.

17. Yes, these side lengths can form a triangle.

-- 5 + 6 = 11

-- 11 is greater than 9, the largest number.

18. Yes, these side lengths can form a triangle.

-- 4 + 5 = 9

-- 9 is greater than 8, the largest number.

It is 15 cm I have the answer on my homework

Answer:

$3072

Step-by-step explanation:

The compound interest formula for the amount paid on the loan P = P₀(1 + rt/100) where P₀ = loan amount = $32,000, r = rate = 4.8 % per annum and t = time

For the 3 year loan, t = 3, So,

P = P₀(1 + rt/100)

P = $32,000(1 + 4.8 × 3/100)

P = $32,000(1 + 14.4/100)

P = $32,000(1 + 0.144)

P = $32,000(1.144)

P = $36608

For the 5 year loan, t = 5, So,

P' = P₀(1 + rt/100)

P' = $32,000(1 + 4.8 × 5/100)

P' = $32,000(1 + 24/100)

P' = $32,000(1 + 0.24)

P' = $32,000(1.24)

P' = $39680

So, the amount more Miranda pay for the 5 year loan than the 3 year loan is P' - P = $39680 - $36608 = $3072

In 3 years Miranda would pay $36,832.72.

In 5 years Miranda would pay $40,453.53.

This question is an illustration of multiplication of fractions. The amount of eaten by Leroy's brother is [tex]\frac 16[/tex]

Given that:

[tex]L = \frac 14[/tex] ----- The left over

[tex]F = \frac 23[/tex]  ----- The fraction eaten by Leroy's brother

The fraction of the whole cake (B) eaten by Leroy's brother is:

[tex]B = L \times F[/tex]

So, we have:

[tex]B = \frac 14 \times \frac 23[/tex]

Cancel out common terns

[tex]B = \frac 12 \times \frac 13[/tex]

[tex]B = \frac 16[/tex]

Hence, Leroy's brother ate [tex]\frac 16[/tex] of the whole cake

No, this is not a correct amount. The correct amount is $203.88

Step-by-step explanation:

The computation of the credit card amount is shown below:

Given that

The credit card is $220.87

But if we calculate the credit card amount, so it would be

Answer: C

Step-by-step explanation:

All the numbers are 78, 80, 83, 84, 84, 86, 89, 91, 95, 100. That’s because for each row, you take the number in the first column, and create each score by putting one of the numbers in the second column next to the first number. The median is the number in the middle if you were to put them out in order. I already listed the numbers in order, and the middle numbers are 84 and 86, so the find the middle of those, you add them together and divide by 2. You get 85, a.k.a. option C.
