Answer: =3.5x Slope:

3.5

y-intercept:

0

Step-by-step explanation:

y=-3.5x-10 is an inverse proportional.

Given that, the given equation is y= -3.5x-10.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

Put x=0, 1, 2, 3, and 4 in the given equation.

When x=0

y=-10

When x=1

y=-3.5(1)-10

=-3.5-10

=-13.5

When x=2

y=-3.5(2)-10

=-7-10

=-17

When x=3

y=-3.5(3)-10

=-10.5-10

=-20.5

Here, x increases and y decreases, it is inverse proportionality

Therefore, y=-3.5x-10 is an inverse proportional.

Answer: $259.20

Step-by-step explanation: Divide $32.40 by 3 to get $10.80. Then multiply $10.80 by 24 (2 years).

Answer:

$259.20

Step-by-step explanation:

32.4·4=129.6

129.6·2=259.2

Additional info

Twelves months in one year so 12÷3=4

Two years so 129.6·2

Just in case you were wondering how I got 4 and 2

Answer:

9°

Explanation:

So, since the arrow is pointing to a RIGHT angle, you have to know the right angle's degree is 90° so set up an equation.

11x - 9 = 90

Now you solve it. Here's a step by step:

11x - 9 = 90

Add nine to nine and ninety. Since the nine in this equation is negative, it'll cancel it out. Now here's what you have left to solve:

11x = 99

Divide -11 from 11 and 99.

x = 9

If you feel like you're wrong, fill it in!

11(9) - 9 = 90

11 x 9 = 99

99 - 9 = 90

There you go!

Answer:

Since the Airbus A300 model airplane was made to scale, measuring 36 centimeters, while the real airplane measures 54 meters, to determine the scale ratio between both planes, the following calculation must be performed:

36cm = 0.36m

0.36 = 1

54 = X

54 x 1 / 0.36 = X

150 = X

Therefore, the scale ratio between the model and the real plane is 150:1.

Yes, the reaction is balanced.

Among the reactants, we have

• 8 carbon

• 20 hydrogen

• 26 oxygen

and among the products,

• 8 carbon

• 16 + 10 = 26 oxygen

• 20 hydrogen

Answer:

Simple Answer... Yes it is balanced.

Answer:

  d.  The triangles are not similar

Step-by-step explanation:

The angle between the given sides is the same, so we need to compare the side ratios. In ΔQRS, we have ...

  QR/RS = 4/15

In ΔVTU, we have ...

  VT/TU = 8/32 = 1/4 ≠ 4/15

The triangles are not similar because corresponding sides are not proportional.

Answer:

1. y = 4x - 4

2. y = x + 2

3. y = -2x - 4

4. y = -x + 2

Step-by-step explanation:

Slope-intercept form is y = mx+b. As we know, m is the slope and b is the y-intercept. We need to find the slope and y-intercept and put them in the equation. Slope is rise over run, so we just count up then over until we get to an intersection. For the y-intercept, we look where the line crosses the y-axis.

41.803 is 42 rounded to the nearest whole number because when you go past .5 you round to the nearest highest number, but when your below .5 then you round to the nearest lowest number.

Answer: 41.803 rounded to the nearest whole number would be 42. Whenever you go over .5 you round to the nearest highest number. For example, 41.6 would also be rounded to 42.

[tex]\boxed{\boxed{\pink{\sf Yes \ it\ is \ one\ to \ one \ function .}}}[/tex]

A function is said to be be one-to-one ( injective) if every y-value has only one corresponding x-value. The given function is ,

[tex]\bf \implies f(x) = 2x^3-5\\\\\bf\implies y = 2x^3-5 [/tex]

Here I have made the graph of " Desoms Graphing calculator. "

Now ,on plotting its graph we see that every y-value has only one corresponding x-value . Hence , ihe given function is a injective function that is one to one function.

Answer:

49m^4 - 25

Step-by-step explanation:

The simpler expression can simply be found by expanding

The kind of expansion we have here is the difference of two squares

(a + b)(a-b) = a^2 - b^2

Thus, we have it that;

(7m^2-5)(7m^2 + 5)

=

49m^4 - 25

Answer:

Francisca was supposed to divide by 1/3, instead of subtracting by 1/3.

Step-by-step explanation:

She was completing the equation correctly until she subtracted 1/3 instead of dividing both sides. It should have been 5 divided by 1/3 or 15/3 divided by 1/3.

Answer:

= 1.072727 games per day

Step-by-step explanation:

This is a fraction equal to

118 games ÷ 110 days

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 110

118 games ÷ 110

110 days ÷ 110

=

1.072727 games

1 day

=

1.072727 games

day

= 1.072727 games per day
