Answer:

gradient = 1

Step-by-step explanation:

calculate the gradient using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (2, 0) ← 2 points on the line

m = [tex]\frac{0-(-2)}{2-0}[/tex] = [tex]\frac{0+2}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1

[tex]\underline{\underline{\large\bf{Solution:-}}}\\[/tex]

[tex]\longrightarrow[/tex]By observing the graph of the line , we can observes that it intersects x- axis at 2 and y -axis at -2 i.e., it passes through (2,0) and (0,-2) respectively.

[tex]\textsf{The gradient of a line passing through two}[/tex][tex]\sf{given \: points \:(x_1,y_1) \:and \:(x_2,y_2) \: is \:given \: by - }[/tex]

Answer:

vanilla=$5 and fruit juice=$3

Step-by-step explanation:

let $x and $y denote the cost of vanilla thickshake and fruit juice respectively.

Now,

$x=$y+2$ (Given)-----(i)

3×$x + 5×$y =30

3×($y+$2)+5×$y=30 (From equation i )

3×$y +$6 + 5×$y = 30

8×$y + $6 = $30

8×$y= $24

.: $y =$3

Then,

From i

$x =$y+$2

=$3+$2

There are 11.9% of the total cost of the loan did her finance charges comprise, the correct option is D.

The total finance charge is the amount of money a consumer pays for borrowing money on a credit card.

Given

Chelsea made monthly payments for four years before her $13,440 loan was paid off.

The loan had an interest rate of 5. 86%, compounded monthly.

Chelsea paid $156. 60 in service charges.

The percentage of the total cost of the loan did her finance charges comprise is;

[tex]\rm\dfrac{ 13,440(\dfrac{0.0586}{12})}{(1-(1+\dfrac{0.0586}{12})^{-48}})= 15,109.44 \\\\15,109.44 + 156.60 = 15,266.04\\\\ 15,266.04 - 13,440.00 = 1,826.04 \\\\=\dfrac{1,826.04}{15,266.04}\\\\ =11.96\ Percentage[/tex]

Hence, there are 11.9% of the total cost of the loan did her finance charges comprise.

Answer:

Step-by-step explanation:

am trying to find the answer

Perimeter: h + h + g +g = P or 2h + 2g = P

P = 2h + 2g

68.4 = 2(4.7) + 2g

68.4 = 9.4 + 2g

59 = 2g

g = 29.5

Answer:

Therefore, they can buy

6.36 bats and 12.72gloves

Step-by-step explanation:

Let us represent:

The number of bats purchased = b

The number of gloves purchased = g

We are told in the question that:

The number of bats they will purchase is half the number of gloves

b = 1/2g

b = g/2

g = 2b

The teams plan to purchase bats that cost $60 each and gloves that cost $25 each. they will purchase. If they have $700, how many of each can they buy?

Hence:

$60 × b + $25 × g = $700

= 60b + 25g = 700

We substitute 2b for g

60b + 25(2b) = 700

60b + 50b = 700

110b = 700

b = 700/110

b = 6.3636363636

b = 6.36 bats

Therefore, the number of bats they can buy = 6.36 bats

Remember:

g = 2b

b = 6.36

Hence,

g = 2 × 6.36

g =12.72

Therefore, the number of gloves = 12.72 gloves

Answer:

y = -4

Step-by-step explanation:

Since x and y vary inversely, we have:

xy=k

For x= -2 and y = -8, we have:

⇒  -2×-8=k

⇒  k= 16

For x= -4, we have :

⇒  -4y=16

⇒  y= 16/-4

⇒  y=  -4

[RevyBreeze]

Answer:

y = -4

Step-by-step explanation:

The equation for inverse variation is

xy = k where k is a constant

x=-2 and y = -8  so we can find k

-2 * -8 = k

16 = k

The equation is xy = 16

Know we want to find y when x = -4

-4 *y =16

Divide each side by -4

-4y /-4 = 16/-4

y = -4

Given that Jordan started at her home at point h she ran to the bank library post office at point B the café and then back to her home The coordinates the position in the miles of each of these locations with respect messenger tell which is located at the origin.

The total distance travelled will be the magnitude in miles from point h to B plus the magnitude in miles from point B to the cafe plus magnitude in miles from cafe back to point B plus the magnitude in miles from point B back to point h.

That is,

If the displacement from point h to b = x

And from B to the cafe = y

Then the total distance travelled will be

Distance = 2x + 2y

Problem 1

Slope = 3/4

Y intercept = -5

You have the right idea for the slope, but I would use a slash as shown above to indicate a fraction. It looks like you're subtracting 3 and 4 based on what you typed in. Though that might be the division symbol (it's a bit blurry so I can't see it fully/clearly)

Answer:

[tex]Profit = \$117.7[/tex]

Step-by-step explanation:

Given

Selling Price of:

[tex]Cookies = \$4.01[/tex]

[tex]Brownie = \$4.1[/tex]

[tex]Cake = \$30.54[/tex]

Quantities Sold:

[tex]Cookies = 13[/tex]

[tex]Brownies = 5[/tex]

[tex]Cake = 3[/tex]

Cost Price:

[tex]Cookies = \$1.79[/tex]

[tex]Brownie = \$0.63[/tex]

[tex]Cake = \$6.71[/tex]

Required

Determine the profit

First, we need to calculate the total cost price:

Total Cost Price = Item Cost Price * Quantity ---- For each

i.e.

[tex]Total\ Cost\ Price = \$1.79 * 13 + \$0.63 * 5 +\$6.71 * 3[/tex]

[tex]Total\ Cost\ Price = \$23.27 + \$3.15 +\$20.13[/tex]

[tex]Total\ Cost\ Price = \$46.55[/tex]

Then, the total selling price

Total Selling Price = Item Selling Price * Quantity ---- For each

[tex]Total\ Selling\ Price = \$4.01 * 13 + \$4.1 * 5 + \$30.54 * 3[/tex]

[tex]Total\ Selling\ Price = \$52.13 + \$20.5+ \$91.62[/tex]

[tex]Total\ Selling\ Price = \$164.25[/tex]

Profit is calculated as thus:

[tex]Profit = Total\ Selling\ Price - Total\ Cost\ Price[/tex]

[tex]Profit = \$164.25 - \$46.55[/tex]

[tex]Profit = \$117.7[/tex]

Answer:

Step-by-step explanation:

Flat Raise: With a flat raise, you will determine how much additional money you would be getting as a flat sum, which adds to your annual salary. You can also figure out weekly, bi-weekly, or semi-monthly pay by dividing the yearly amount by the appropriate period. But if math isn’t your strong suit, our pay raise calculator will automatically determine that for you.

For example, let’s say that your gross annual wages are $30,000, with weekly payments of $577 going your way. You currently have 33 hours per week on average, and your employer proposes to give you a flat raise of $1,200. You want to determine how much their weekly pay will be and how much more you will ultimately receive. Add their current gross wages to the Current Pay with the Pay Period set to Annual. Insert the Flat Raise amount of $1,200 and press “Calculate.” You’ll get a new weekly payment of $600 with a total difference of $23.
