Can someone help me understand this!!!

Mathematics
1 answer:
otez555 [7]4 years ago
4 0

Answer:

7b, 8a

Step-by-step explanation:

using the equation y=m(x)+b, m(x) is the slope, and b is the y intercept. Oky so for 7, its a slope of negative 2, and it has a y-intercept of 5, and if you look at graph b a  slope of -2 and would be a y-intercept of 5.

looking at equation a, its a Quadric function, f(x)=x^2, but it doesn't match the graph... strange because the graph for that equation would look like the image included. Hopefully this helps!

Please help I'm so confused! I need the surface area. Thank you
kondaur [170]

Answer:

The answer is : 23.25 in ²

Step-by-step explanation:

There are 3 triangles with the same lengths: height = 5in and base = 5 in

There is one triangle: height = 4.3 in base = 5 in

Formula

Area = height x base / 2

For the triangles

Area = 5 in x 5 in /2 = 25 /2 = 12.5 in²

For the triangle

Area = 4.3 x 5 /2 = 21.5 /2 = 10.75 in²

Total surface area = 12.5 + 10.75 = 23.25 in²

What property is used to rewrite (x + 2)(y + z) as y (x + 2) + z (x + 2)
andreyandreev [35.5K]

Answer:

<u>Distributive Property</u>

Step-by-step explanation (if you were to show the steps):

(x+2)(y+z)   <u>(first expression)</u>

xy + xz + 2y + 2z <u>(Distributive Property of Multiplication)</u>

yx + 2y + zx + 2z <u>(use the Commutative Property of Addition and Commutative Property of Multiplication to group xy (also known as yx) and 2y together, and to group xz (also known as zx) and 2z together)</u>

y(x + 2) + z(x + 2) <u>(use factoring to get the rewritten expression at the end)</u>
