Answer:

3(7) - 4 = 17

Step-by-step explanation:

Substitute 7 for x and solve.

Answer:

x=3

y=-1

Step-by-step explanation:

first multiply the 2nd row by 2 so you will get

4x-4y=16

4x+2y=10

then subtract the 2nd row from the first row and so you will get

-6y=6

then solve for y in the above equation

y=-1

then substitute y=-1 into any 2 equations .

i picked the first 1

4x-4 × -1=16

then solve for x .

you will get

x=3

Answer:

134.62

Step-by-step explanation:

Answer: A

Explanation:

Step 1: Use the linear graph to create an equation using slope-intercept form. The y-intercept is (0,-6) because that's where the line passes the y-axis. The slope is 1/2 and that's pretty self-explanatory if you know how to find slope. The equation would be y=1/2x-6.

Step 2: Because we are looking for a line perpendicular to the linear graph, the y-intercept and slope needs to be different. If they're perpendicular, they need to intersect, so the slope needs to be the reciprocal of the original slope, 1/2. The reciprocal is -2. Your equation would be y=-2x+b, and since we don't know the y-intercept, we would leave it as b.

Step 3: Plug in the given ordered pair, (-3,-2), to get -2=-2(-3)+b. You would result with -2=6+b. Subtract 6 to both sides and you would get b=-8.

Answer:a and d

Step-by-step explanation:

Answer:

16 x 0,75

(0,75 = 3/4) so you could take 3 x 16 = 48 and then take 48/4 and the answer should be 12 but the percent is 75%

Answer: n=3

Step-by-step explanation:

Understand that you need to set up a proportion before you can try to solve the question through guessing. In this case, YZ would be proportional to XY as EF is proportional to DE. You would write this as: EF/DE=YZ/XY.

Now you want to write an equation. In order to do this remember to multiply by your proportion. Here’s my equation:

5/4(4n+4)=7n-1. Now distribute:

5n+5=7n-1. Now simplify:

6=2n. Now simplify again:

n=3

Hope this helps you with your big ideas math hw!

The value of is n=3

5/4(4n+4)=7n-1.

Now distribute:

5n+5=7n-1.

Now simplify:

6=2n.

n=3

Answer:

A. [tex] PR = 80.6 yd [/tex]

B. Perimeter = 190.6 yd

Step-by-step explanation:

A. Distance between P(10, 50) and R(80, 10):

[tex] PR = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] PR = \sqrt{(80 - 10)^2 + (10 - 50)^2} [/tex]

[tex] PR = \sqrt{(70)^2 + (-40)^2} [/tex]

[tex] PR = \sqrt{4,900 + 1,600} [/tex]

[tex] PR = \sqrt{6,500} [/tex]

[tex] PR = 80.6 yd [/tex] (nearest tenth)

B. Distance around the park = Perimeter = PR + PQ + QR

PR = 80.6 yd

PQ = |50 - 10| = 40 yd

QR = |80 - 10| = 70 yd

Perimeter = 80.6 + 40 + 70

Perimeter = 190.6 yd

Answer:

Step-by-step explanation:

It literally says $500 on the table hope this helps :D

Hope this helps :D Please hit the crown if you want me to help you on the last one then tell me and make a new question !!!!!!!!!!!!

Answer:

500, x times 500 = y

Step-by-step explanation:

Question 1: $500, if you look at the table underneath the section for "one" compute it says 500 in the cost section.

Question 2: X times 500 = Y (since for every "x" (computer) there is $500 "y" (cost))

Answer:

B. $39550

Step-by-step explanation:

The expression for the function is not well-formatted, find the correct format in the solution bellow

Step one:

given data

We are told that the function of the cost is

[tex]C(t) = 0.04t^3- 0.1t^2 + 5.5t[/tex]

instantaneous rate c(t) is the value obtained when we plug in 100 for t in the function above

substituting we have

[tex]C(t) = 0.04(100)^3- 0.1(100)^2 + 5.5(100)\\\\\C(t) = 0.04*1000000- 0.1*10000 + 5.5*100\\\\C(t) = 40000-1000+550\\\\C(t) = 39550[/tex]

$39550

Answer:

A = Hard to do, B = Easiest, C = Pretty Easy, D = Hard

Step-by-step explanation:

Step 1:

5x - 2y = -18

x - 8y = 80

__________

Step 2:

4(5x - 2y) = (-18)4

20x - 8y = -72

__________

Step 3:

20x - 8y = -72

x - 8y = 80

__________

Step 4:

21x = ?

Also, this equation isnt a substitution question, the way to solve this is by using elimination, you can tell because the values are lined up perfectly, sub. is used when y/x, is on the bottom left or right, and the other is on the opposite.

Answer:

500

Step-by-step explanation:

each computer is 500 dollars

Answer:

500

Step-by-step explanation:

Divide each cost by the number of computers

500 ÷ 1 = 500

1,000 ÷ 2 = 500

1,500 ÷ 3 = 500

2,000 ÷ 4 = 500

Answer:

[tex]\left(x-10\right)-\left(2x-5\right)^2=-4x^2+21x-35[/tex]

Step-by-step explanation:

As we have to subtract [tex]\left(2x\:-\:5\right)^2[/tex] from [tex]\left(x-10\right)[/tex]

so

[tex]\left(x-10\right)-\left(2x\:-\:5\right)^2[/tex]

solving and simplifying the polynomial in standard form

[tex]\left(x-10\right)-\left(2x-5\right)^2[/tex]

[tex]\mathrm{Remove\:parentheses}:\quad \left(a\right)=a[/tex]

[tex]=x-10-\left(2x-5\right)^2[/tex]

[tex]=x-10-\left(4x^2-20x+25\right)[/tex]      ∵ [tex]\left(2x\:-\:5\right)^2=\:4x^2-20x+25[/tex]

[tex]=x-10-4x^2+20x-25[/tex]

[tex]=-4x^2+21x-35[/tex]

We know that standard form means that the terms of the expression are ordered from biggest exponent to lowest exponent.

Thus, a simplified polynomial in standard form is:

[tex]\left(x-10\right)-\left(2x-5\right)^2=-4x^2+21x-35[/tex]
