Answer:
B. Graph D
Step-by-step explanation:
Start with the vertex formula for each, <em>y</em><em> </em><em>=</em><em> </em><em>a</em><em>(</em><em>x</em><em> </em><em>-</em><em> </em><em>h</em><em>)</em><em>²</em><em> </em><em>+</em><em> </em><em>k</em><em>,</em><em> </em>where (<em>h</em><em>,</em><em> </em><em>k</em>) → (<em>2</em>, <em>0</em>) is the vertex, plus, -h gives you the OPPOSITE terms of what they really are, and k gives you the EXACT terms of what they really are. So, insert the vertex into the Vertex Equation FIRST, y = (x - 2)². We reason why there is no <em>k</em><em> </em>is because it is represented by 0. So, squaring this monomial will give us <em>x</em><em>²</em><em> </em><em>-</em><em> </em><em>4x</em><em> </em><em>+</em><em> </em><em>4</em><em>.</em><em> </em>Ta Da!

C^2-10c+24 this is the answer. You have to use foil.
Answer:
Step-by-step explanation:
It's $3.90 for every 30 meters. Or $0.13 for every meter.
b is two fifths of c, so we make this a ratio with c = 1.
The ratio of b:c is 2/5 : 1
We also have 4a = 3c, rewrite this ratio so c is 1 by dividing both sides by 4,
so we get the ratio of a to c as 3/4 : 1
Now we get the a:b:c ratio of 3/4 : 2/5 : 1 now we can change the fractions to whole numbers, first by multiplying the 3 numbers by 4 to get get rid of the denominator of 4 in a:
3 : 8/5 : 4
Now multiply the 3 numbers by 5 to remove the denominator of 5 in b:
15 : 8 : 20
Now we can check using the equations:
b is 2/5 of c: 20 x 2/5 = 40/5 = 8 This is true.
4a = 3c: 4(15) = 3(20) = 60 = 60, this is also true.
The ratios is 15 : 8: 20
Answer:
x = 12
Step-by-step explanation:
5x - 30 = 2x + 6
3x = 36
x = 12
