(Level 4) In a bag of orange, red, and yellow, 60% are orange, and 10% are red. There

1 answer:

3 0

The answer is 22 orange marbles. Let me explain. Since 60% are orange and 10% are red, the rest, 30% is yellow. So we learn that every 10% equals to 2 marbles. If you add 60% + 50% = 110%

90% = 18

And we have to add 4 more because 10%×2.

So the total comes to 18+4= 22.

The function of f(x) is to be graphed on a coordinate plane f(x) {-x x<0 1. X>0}

serg [7]

Answer:

The graph is attached

Step-by-step explanation:

Here the given function is

$f(x) = \left \{ {{-x}, x < 0 \atop {1}, \\ x > 0} \right.$

Now consider

y = -x

The graph is a line at 45° to the negative x axis.

But as x <0, so it shall be a line only in the second quadrant.

Also for f(x) = 1

It a horizontal line passing through y axis at 1.

But as x > 0, So we have the line only to the right of y axis.

The graph is attached.

slamgirl [31]

Answer:

D p^2 +3p -10

Step-by-step explanation:

(p+5) (p-2)

FOIL

First p*p = p^2

Outer -2*p = -2p

Inner 5*p = 5p

Last -2 *5= -10

Add them together

p^2 -2p+5p -10

p^2 +3p -10

Write the equation of a circle with a center at<br> (2, -9) and a radius of 7<br> Helpppp

siniylev [52]

Answer:

$x^2+y^2+14y+36=0$

Step-by-step explanation:

Given that,

Center = (2,-9)

Radius of the circle, r = 7

We need to find the equation of a circle with a center at (2, -9) and a radius of 7. It can be given by :

$(x-h)^2+(y-k)^2=r^2$

Put h = 2, k = -9 and r = 7 So,

$(x-2)^2+(y-(-9))^2=7^2\\\\x^2+4-4x+y^2+81+18y=49\\\\x^2+y^2+14y+85-49=0\\\\x^2+y^2+14y+36=0$

Hence, this is the required solution.

The sum of two numbers is 44 and the difference is 14. What are the numbers?

Fudgin [204]

Answer:

Hope it may help u

Step-by-step explanation:

The sum of two numbers is 44 and their difference is 14. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.

The sum of x and y is 44. In other words, x plus y equals 44 and can be written as equation A:

x + y = 44

The difference between x and y is 14. In other words, x minus y equals 14 and can be written as equation B:

x - y = 14

Now solve equation B for x to get the revised equation B:

x - y = 14

x = 14 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 44

14 + y + y = 44

14 + 2y = 44

2y = 30

y = 15

Now we know y is 15. Which means that we can substitute y for 15 in equation A and solve for x:

x + y = 44

x + 15 = 44

X = 29

Summary: The sum of two numbers is 44 and their difference is 14. What are the two numbers? Answer: 29 and 15 as proven here:

Sum: 29 + 15 = 44

Difference: 29 - 15 = 14
