Answer:
x=2.5&.5
Step-by-step explanation:
The quadratic formula is (-b+or-sqrt(b^2-4ac)/2a
12+or-sqrt((-12^2)-4(4)(5))
12+or-sqrt(144-80)
12+or-sqrt(64)
(12+8)/8 and (12-8)/8
x=2.5 and x=.5
Answer:
<em>firstly</em><em> find</em><em> the</em><em> gradient</em><em> given</em><em> by</em><em> the</em><em> equation</em>
<em>m=</em><em>y2-y1</em><em>/</em><em>x2-x1</em>
<em>in this </em><em>case</em><em> </em><em>x1 </em><em>is </em><em>-</em><em>1</em><em>2</em><em>,</em><em>x2 </em><em>is </em><em>-</em><em>1</em><em>7</em><em>,</em><em> </em><em>y1 </em><em>is </em><em>-8 </em><em>and </em><em>y2 </em><em>is</em><em>-</em><em>1</em><em>6</em>
<em>m=</em><em>-</em><em>1</em><em>6</em><em>+</em><em>8</em><em>/</em><em>-</em><em>1</em><em>7</em><em>+</em><em>1</em><em>2</em>
<em> </em><em> </em><em> </em><em>=</em><em>-</em><em>8</em><em>/</em><em>-</em><em>5</em><em> </em><em>or1.</em><em>6</em>
<em>then</em><em> </em><em>use </em><em>the </em><em>equation</em>
<em>y-y1</em><em>=</em><em>m(</em><em>x-x1</em><em>)</em>
y+8=1.6(x+12)
y+8=1.6x+19.2
y=1.6x+11.2

Answer:
We verified that the equation 
has both sides equal.
Step-by-step explanation:
We need to solve and verify:
Solving:
Converting into improper fractions
Converting division sign into multiplication and reversing 3/2 i.e
Now simplifying
So, We verified that the equation has both sides equal.
Answer: You have to find the unit rate so you divide 7.50 by 3 which is 2.50 so for 1 pound it is 2.50, 2 pounds is 5, 3 pounds is 7.50, 4 pounds is 10, and 5 pounds is 12.50
Step-by-step explanation:
