Answer:

eqn of line

5x-y=-9

Step-by-step explanation:

Answer:

y = 5x + 9

Step-by-step explanation:

Assuming you require the equation.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 5 , thus

y = 5x + c ← is the partial equation

To find c substitute (- 1, 4) into the partial equation

4 = - 5 + c ⇒ c = 4 + 5 = 9

y = 5x + 9 ← equation of line

Answer: The length of JF = 16 units.

Step-by-step explanation:

Given: In triangle DEF, segment DJ is a perpendicular bisector of side EF.

i.e. DJ is perpendicular to EF and DJ divides EF into two equal parts EJ and JF. [The perpendicular bisector is a line that is perpendicular to a line segment and splits it into two congruent segments.]

If  EJ is 3y-8 and JF is 7y-40.

Then, [tex]3y-8=7y-40[/tex]

[tex]\Rightarrow\ 7y-3y=40-8\\\\\Rightarrow\ 4y=32\\\\\Rightarrow\ y=8 \text{ [Divide both sides by 4]}[/tex]

JF= 7(8)-40 =56-40= 16 units

Hence, the length of JF = 16 units.

Answer:

x = 6

y = [tex]3\sqrt{2}[/tex]

Step-by-step explanation:

Thats a 45 45 90 triangle, one of my favorite and you'll come to miss it later because of how easy it is.

See the file provided for the trick

Because [tex]3\sqrt{2}[/tex] falls where a 1 is in the diagram that means y is also [tex]3\sqrt{2}[/tex] because you multiply [tex]3\sqrt{2}[/tex] by 1, and to get x you'll multiply the value we're given, [tex]3\sqrt{2}[/tex], by the value in the spot in the given diagram, [tex]\sqrt{2}[/tex].

[tex]3\sqrt{2}[/tex] ×[tex]\sqrt{2}[/tex]

Note; a radical multiplied by itself is the value in the radical

Therefore,

[tex]3\sqrt{2}[/tex] ×[tex]\sqrt{2}[/tex] = 3(2) = 6

Thus x = 6

The explanation for this;

[tex]\sqrt{2}[/tex] * [tex]\sqrt{2}[/tex] = [tex]\sqrt{2}^2[/tex]

And if you square a square root you have its square root times its square root squared, which if it was [tex]\sqrt{4}^2[/tex] it'd ultimately be [tex](2)^2[/tex] which is 2x2 which equals 4

Answer:

Step-by-step explanation: The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.

Answer:

Paste is the answer if I remember

So first of all you count all the blocks, so it will be 16 blocks (4x4) sideways and horizontal.

A = 16/4 marked blocks = 25%

B = 16/8 marked blocks = 50%

C = 16/6 marked blocks = ?

D = 16/10 marked blocks = 62,5%

So answer would be A

Answer:

10 to 8

Step-by-step explanation:

1) Try to simplify all of the answer choices

2) Divide all of the numbers by 2

3) Then you'll find that 10 to 8 is equal to 5 to 4

Answer:

5

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

Given:

The inequality is

[tex]2n+8>12[/tex]

To find:

The solution of the given inequality.

Solution:

We have,

[tex]2n+8>12[/tex]

Subtract 8 from both sides.

[tex]2n+8-8>12-8[/tex]

[tex]2n>4[/tex]

Divide both sides by 2.

[tex]\dfrac{2n}{2}>\dfrac{4}{2}[/tex]

[tex]n>2[/tex]

It means, the value of n is greater than 2.

Therefore, the solution of given inequality is n > 2.

11?

Step-by-step explanation:

Answer:

probaly about ten or 11 five four times is 20 and they are 22

Step-by-step explanation:

5 + 5 +5 +5=20

then you would do 2 x 4 since five is four times

2 x 4 = 8

so i would round up

Answer:

Step-by-step explanation:

  Step one:

Given that membership is $9 and the cost per visit is $1

let the number of visits be x

and the total cost be y

the total cost  for the situation is modeled as

y=mx+c-----equation of a line

   Step two:

given that x=23, we can solve for the totals cost as

by substituting we have

y=1*23+9

y=23+9

y=32

The total cost for 23 visits is $32
