The answer is 8 and 13

<span>
y = ax + b
y = 4, x = 1 </span>⇒ 4 = a + b
y = 6, x = 3 ⇒ 6 = 3a + b

Solve the system of equation:
a + b = 4
3a + b = 6
______
b = 4 - a
3a + b = 6
______
3a + 4 - a = 6
2a + 4 = 6
2a = 6 - 4
2a = 2
a = 2/2 = 1
b = 4 - a = 4 - 1 = 3

So, the function rule is: y = x + 3

Thus, if x = 7, then y = 7 + 3 = 10
If x = 10, then y = 10 + 3 = 13

x y
1 4
3 6
4 7
5 8
7 10
10 13

What are the zeros of the graphed function y = (x + 3)(x + 5)? –5 and –3 5 and 3 –8 and 5 0 and 5

Sati [7]

Answer:

Answers are: (x+3)(x+5) = 0

So first zero: x+3 = 0 so x = -3

Second zero: x+5 = 0 so x = -5

so zeros are: x = -5 and -3

Can somebody help me find the surface area of this

-Dominant- [34]

Answer:

G. 7600 $cm^{2}$

Step-by-step explanation:

Step 1: Deconstruct the shape

2 rectangles with dimension of 50 cm x 20 cm

2 rectangles with dimension of 40 cm x 20 cm

2 rectangles with dimension of 40 cm x 50 cm

Step 2: Find surface area of the shapes

2(50 x 20) = 2000 $cm^{2}$

2(40 x 20) = 1600 $cm^{2}$

2(40 x 50) = 4000 $cm^{2}$

Step 3: Add the surface areas together

2000 + 1600 + 4000 = 7600 $cm^{2}$

Therefore the surface area is 7600 $cm^{2}$ and the answer is G.
