In math, slope<span> is the ratio of the vertical and horizontal changes between </span>two points<span>on a surface or a line. The vertical change between </span>two points<span> is called the rise, and the horizontal change is called the run. The </span>slope<span> equals the rise divided by the run: . This simple equation is called the </span>slope formula<span>.</span>
X-intercepts are points where the graph intersects the x-axis, i.e. when y=0.
Substitute y=0 and solve for x:
y=x^2-3x+2
0=x^2-3x+2
0=(x-2)(x-1)
By the zero product property, we deduce x-2=0 or x-1=0, i.e. x=1 or x=2.
x = -21
explanation: a trick i used was just do -3 times 7 and get my answer -21. if you are unsure if the answer is right just check your work with a calculator. -21 divided by 7 is -3 so -21 is the value of x. please mark brainliest !!
Answer:
C
HOWEVER: "Less Than" is usually depicted as a dashed line at the border. and there MUST be an OR between these two equations to include all of the blue area. An "and" there would exclude the area between the edge lines.
Step-by-step explanation:
2x + y < 10
y < -2x + 10
3x + 2y < 12
2y < -3x + 12
y < -1.5x + 6
Considering the situation described, we have that:
a. x = 65 - 8 = 57.
b. You won the game, as you scored 137 and your friend 130.
<h3>What is the equation for the situation after five frames?</h3>
Your friend's score is of 65, and your score of x is 8 less than your friend, hence the equation is:
x = 65 - 8 = 57.
<h3>What are the final scores?</h3>
Your friend score doubled, hence his/her final score is:
2 x 65 = 130.
Your score increased by 80, hence your final score is:
57 + 80 = 137.
You won the game, as you scored 137 and your friend 130.
