X + 3 = y

Try substitute every number with the equation above.

Sub x=-4 and y=-1,
-4 + 3 = -1

-1 = -1

Sub x=-3 and y=0
-3 + 3 = 0

0 = 0

Sub x=-2 and y=1
-2 + 3 = 1

1 = 1

Sub x=-1 and y=2
-1 + 3 = 2

2 = 2

Hope it helps!

What is the surface area of a sphere with a radius of 11 units

Otrada [13]

Answer: A≈1519.76³ Units

Step-by-step explanation:

A=4πr²

r = 11

11²=121

121 * 3.14 = 379.94

379.94(4) = 1519.76

A≈1519.76³ Units OR

A=4πr2=4·π·112≈1520.53084

This table gives points on a line. What is the equation of the line?

vitfil [10]

Answer:

y = -2x + 5

Step-by-step explanation:

Assuming this is linear, the slope would be constant. For every 1 x, y decreases by 2. This means that the slope is -2.

y = -2x + b

Now all we need is the y-intercept.

If we plug in the first point (1,3), we get:

3 = -2*1+b

3 = -2+b

b = 5

This is the y-intercept.

y = -2x + 5

Jerome is going to draw a marble from the bag shown below, replace it, and then draw another marble. What is the probability tha

alexira [117]

Marbles in a bag: 3 green, 4 yellow, 5 blue, 8 pink.

Event A - get a green or yellow marble
Event B - get a pink marble

Events A and B are independent because we draw a marble from a bag with 20 marbles in both cases.
$P(A)= \frac{3+4}{3+4+5+8}= \frac{7}{20} 
\\P(B)= \frac{8}{3+4+5+8}= \frac{8}{20} = \frac{2}{5}$

Probability of combined events is
$P(A) \times P(B)=\frac{7}{20} \times \frac{2}{5} =\frac{7}{50}$

Len walks 3/10 mile in the morning. He walks 2/5 mile in the afternoon to a friends house. Len says that he walks a total of 5/1

andre [41]

No he walks 7/10 of a mile
you have to make 2/5 have a common denominator with 3/10
so 2×2=4 (numerator)
2×5=10 (denominator)
4/10+3/10= 7/10
since you only add the numerator because the denominator makes it a like term
