Answer:

The statement is false.

Step-by-step explanation:

The system of equations is given by,

$-5x+y= -2$

$3x+5y= -12$

On substituting (0,-2) in the equations, we get,

$-5\times 0+(-2)=0 -2=-2$

$3\times 0+5\times (-2) = 0-10=-10\neq -12$

Since, we see that,

The point (0,-2) does not satisfy the equation $3x+5y= -12$ .

Thus, the statement is false.

Four players scored all of the points for their team in a basketball game. Player A scored 35 of the points, Player B scored 8%,

Player C scored 0.15 = 15% of the total.
Player D scored 17/100 = 17% of the total.
The total of the given percentages is 8 + 15 + 17 = 40, so Player A must have scored 60% of the total.

In order least to greatest, they are
Player B, Player C, Player D, Player A.

Evan and Brayden want to know if they have more X Box games than Reid and Bryce do

luda_lava [24]

Answer:

Step-by-step explanation:

Evan has 43 and Brayden has 42. Reid has 76 and Bryce has 23. Which pair of boys has more? How much more do they have?

Reid and Rryce have more. If you add 43 and 42 you get 85 and when you add 76 and 23 you get 99. So now subtract 99 and 23 which is 76.

PLEASE HELP MATH QUESTION !!! Explain!

When we say two quantities $x$ and $y$ are proportional to one another, there are two ways we could mean this.

- If $x$ is *directly* proportional to $y$ , then we mean that as $x$ changes, $y$ changes in the same direction. In other words, if $x$ is in/decreased, then $y$ also in/decreases. The rate of in/decrease doesn't have to be one-to-one; for example, we could have $x$ increase by 1 unit while $y$ would proportionally increase by 5 units. In this case, we'd have $y=5x$ .

- On the other hand, if $x$ is *inversely* proportional to $y$ , then a change in $x$ results in a change in $y$ that goes in the opposite direction. A common example involves taking a rectangle of constant area and adjusting the width $x$ and length $y$ . If the rectangle has an area of 5 square units, then we could have $x=5$ and $y=1$ , or we could have $x=4$ and $y=\dfrac54$ , or $x=3$ and $y=\dfrac53$ , or any combination of $x$ and $y$ such that $xy=5$ is satisfied.

In both cases, we call 5 the "constant of proportionality".

On to your exercises:

(1a) Looks like $a$ stands for number of apples. Then we're told that the cost $c=2.3a$ , which means that for every apple, the cost increases by 2.3 dollars. So the constant of proportionality is 2.3. In the language of proportionality, we could then say that the cost of apples is directly proportional to the number of apples by a factor of 2.3.
