Hi there!

I believe your answer is:
"Line y = −2x + 3 intersects line y = x − 5."
»»————- ★ ————-««
Here’s why:
- When the system of equations are graphed, they would intersect at a point.
- This means that there is a solution to the system. The solution is
. - While the statement that the lines intersect the x-axis is true, the question asks the statement that describes the <em>solution</em>.
- The solution is the point of intersection between the two lines.

Hope this helps you. I apologize if it’s incorrect.
Answer:
9. a = -1
10. b = 20
Step-by-step explanation:
The term "cross multiplying" is used to describe the appearance of the result of multiplying both sides of the equation by the product of the denominators. The result is the left numerator is multiplied by the right denominator, and the right numerator is multiplied by the left denominator. The property of equality that supports this is the multiplication property of equality, which tells you the values of the variables are unchanged if you multiply both sides by the same thing. That multiplier is chosen so that it cancels the denominators.

<h3>10.</h3>
_____
<em>Additional comments</em>
Here are the answer checks:
9. (2(-1) -5)/(3(-1)-4) = (2(-1)-3)/(3(-1)-2) ⇒ -7/-7 = -5/-5 . . . yes
10. (10 -2)/(10 -6) = (10 +2)/(10 -4) ⇒ 8/4 = 12/6 . . . yes

Sometimes this method of solving the problem will result in extraneous solutions. Those will generally be values of the variable that make one or more of the denominators be zero. You must be careful to exclude those values from any possible solution set.
Answer:
i agree with jada
Step-by-step explanation:
i agree with jada because 12 inches are in 1 foot so you need 12 constantly to compare inches and feet
Answer:
Part A
Eagle = 6 lbs * 60%
= 6 * 0.6
= 3.6 pounds
Bear = 105 lbs * 25%
= 105 * 0.25
= 26.25 pounds
3.6 + 26.25 = 29.85 pounds
Part B
Percent Increase = Change/Original * 100
= 10/105 * 100
= 9.52%
Answer:
Step-by-step explanation:
y = 3x + 4, and
y = x + 2
------------------
Use the vale of y in the 2nd equation in the first:
y = 3x + 4
x + 2 = 3x + 4
-2x = 2
x = -1
Use this value of x (-1) in either equation to find y:
y = x + 2
y = -1 + 2
y = 1
==========
(-1,1)
