Answer:

The answer is z = -2

Step-by-step explanation:

You combine like terms.

Then subtract 7z from both sides.

Add 10 to both sides.

Then divide both sides by -14. (28/-14)

Which then equals to -2

25 loonies i think but im not so sure

Answer:

The answer is 5/25 you just switch it

Answer:

number is 5

Step-by-step explanation:

The reciprocal of a number n is [tex]\frac{1}{n}[/tex] , thus

n - [tex]\frac{1}{n}[/tex] = [tex]\frac{24}{5}[/tex]

Multiply through by 5n to clear the fractions

5n² - 5 = 24n ( subtract 24n from both sides )

5n² - 24n - 5 = 0 ← in standard form

(n - 5)(5n + 1) = 0 ← in factored form

Equate each factor to zero and solve for n

n - 5 = 0 ⇒ n = 5

5n + 1 = 0 ⇒ 5n = - 1 ⇒ n = - [tex]\frac{1}{5}[/tex]

However, n > 1 , thus n = 5

That is the number is 5

Answer:

Total Amount spent on all the cards = $ 42.3

No of cards  = 16 .

Step-by-step explanation:

The cost is calculated by multiplying the number of items with their costs. As we have different costs for each card we will add the costs of different cards to get the total costs.

Janet buys 3 postcards for $1.05.

Janet spends 3* $1.05= $ 3.15

Rosie buys five postcards for $1.75

Rosie spends 5 * $ 1.75= $ 8.75

Tanya buys eight postcards for $3.80

Tanya spends 8 * $3.80 = $ 30.4

Total Amount spent on all the cards = $ 3.15+$ 8.75+$ 30.4= $ 42.3

No of cards = 3 + 5+ 8= 16 cards were bought .

Answer:

B. y=3/4x+6

Step-by-step explanation:

tttttttttttttt

Answer: B

Step-by-step explanation: the y-intercept is always the b in the equation y=mx+b. in this case it’s 6. Then you look at the rise and the run. its 3/4 because you go up 3 units, and to the right 4 units, to get to the next coordinate point.

Answer:

(f - g)(x) = -x² + 3x + 7 ⇒ D

Step-by-step explanation:

In the expression x - a, you will subtract a from x

Let us solve the question using this fact

∵ f(x) = 3x + 1

∵ g(x) = x² - 6

→ We need to find (f - g)(x), which means subtract g from x

∵ (f - g)(x) = (3x + 1) - (x² - 6)

→ The negative sign before (x² - 6) will change their signs

∵ - (x² - 6) = -(x²) + -(-6)

→ Remember (-)(+) = - and (-)(-) = (+)

∴ - (x² - 6) = -x² + 6

→ Substitute it in (f - g)(x)

∴ (f - g)(x) = 3x + 1 - x² + 6

→ Add the like terms

∴ (f - g)(x) = 3x - x² + (1 + 6)

∴ (f - g)(x) = 3x - x² + 7

→ Re-arrange the terms from the greatest power of x

∴ (f - g)(x) = -x² + 3x + 7

Answer:⬇️

Step-by-step explanation:

Reorder 5 5 and 5x 5 x . Using the slope-intercept form, the slope is 5 . The equation of a perpendicular line to y=5x+5 y = 5 x + 5 must have a slope that is the negative reciprocal of the original slope.

Step-by-step explanation:

Answer:

72773100000%

Step-by-step explanation:

"Percent" means "per 100" or "over 100". So, to convert 727731000 to percent we rewrite 727731000 in terms of "per 100" or over 100.

Multiply 727731000 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.

7277310001×100100=72773100000100

72773100000/100 is 72773100000 over 100 and means 72773100000 per 100. 72773100000 "per 100" means 72773100000 "percent" or 72773100000%

Therefore, we have shown that

727731000 = 72773100000%

Simplified Conversion:

Multiply by 100 and add the percent sign %

727731000 × 100 becomes 72773100000%

Shortcut Conversion:

Move the decimal point 2 places to the right and add the percent sign %

727731000 becomes 72773100000%

Step-by-step explanation:

Answer: Each fundraiser need to raise $ 135.59  in order to purchase the new net and equipment.

Step-by-step explanation:

Money required = $ 842.36

Donation amount = $ 300.00

Amount left to arrange  =  (Money required - Donation amount )

= $ (842.36- 300.00)

=  $ 542.36

Number of fundraisers = 4

Money required to arrange by each fundraiser = (Amount left to arrange) ÷4

= $ (542.36÷4)

= $ 135.59

Hence, each fundraiser need to raise $ 135.59  in order to purchase the new net and equipment.

Answer:

C

Step-by-step explanation:

perpendicular lines intersect at a 90 degree angle, meaning it is not answer choice A.

B is incorrect because perpendicular lines intersect, so they can not be parallel.

C is correct because parallel lines never intersect, so perpendicular lines can never be parallel to each other.

D is incorrect because perpendicular lines only intersect at one point and create four consistent right angles.

Answer:

 1728000

Step-by-step explanation:

You always work from the parenthesis first because of order of operation. You have 12( because 2 times 6) then mulitply 12 times 10. You get 120 then you multiply it but itself 3 times. 120 x 120 x 120= 1728000

Answer:

Step-by-step explanation

(2×6)×10^3

(12)10^3

(12)1000

=12,000

= 2x = 9

= x = 9 ÷ 2 ( transposing ×2 from LHS to RHS changes ×2 to ÷2 )

= x = 4.5

Therefore , x = 4.5 .
