RE
You just looked at the graph of this system of equations.
Why will the lines never intersect?
y = -x +5
y=-x-3
Answers
Answer:
The lines never intersect because the lines are parallel.
Step-by-step explanation:
Given system of linear equations is:
y = -x +5
y=-x-3
The slope-intercept form of a line is:
[tex]y = mx+b[/tex]
Here b is the y-intercept and the co-efficient of x is the slope of the line
Comparing the given equations with slope intercept form we get that the slope of both lines is -1
Both lines have the equal slope which means that the lines are parallel.
Parallel lines NEVER intersect each other.
Hence,
The lines never intersect because the lines are parallel.
What is the equation of the line that goes through (-3,-1) and (3,3)?
A. 3x + 2y = 15
B. 3y + 2x = 15
C. 3x − 2y = 3
D. 2x − 3y = -3
Answers
Answer:
Option D
Step-by-step explanation:
m= y2-y1/x2-x1
m=3-(-1)/3-(-3)
m=4/6
m=2/3
y=m*x+c
y=2/3*x+c
sub (3,3)
3=2/3*3+c
3-2=c
1=c
Therefore y=2/3*x+1
y-2/3*x=1
Times by 3
3y-2x=3
2x-3y=-3
Therefore Option D

LaTanya will walk (3 mi/hr) her bike from her house to the
bike shop, which is 1.5 mi from her house, to get the bike
fixed. She expects to wait 30 min for the repair. Then she
will ride (10 mi/hr) her bike home. How long will it take
her to get home?
A)2.12 hr
B)2hr
C)1.15
D)4hr
Answers
Answer:
1.15 hr
Step-by-step explanation:
Given that:
To get bike fixed :
Speed = 3 miles per hour
Distance = 1.5 miles
Time taken = distance / speed
Time taken = 1.5 / 3 = 0.5 hour
Waiting time for repair = 30 minutes = 0.5 hours
Return home :
Speed = 10 miles per hour
Distance = 1.5 miles
Time taken = distance / speed
Time taken = 1.5 / 10 = 0.15 hour
Total time : (0.5 + 0.5 + 0.15) = 1.15 hr
Write the vertex form equation for the graph shown.
Answers
Answer:
The vertex form equation for the given graph is y = -(x - 2)² + 2
Step-by-step explanation:
The vertex form of the quadratic equation is y = a(x - h)² + k, where
a is the coefficient of x²(h, k) are the coordinates of the vertex pointFrom the given figure
∵ The graph is a parabola the graph of the quadratic equation
∵ Its maximum point is (2, 2)
∴ Its vertex is (2, 2)
→ By using the facts above
∴ h = 2 and k = 2
→ Substitute h, k in the form of the equation above
∴ y = a(x - 2)² + 2
→ To find a substitute x and y in the equation by a point on the curve
∵ The point (0, -2) lies on the parabola
∴ x = 0 and y = -2
→ Substitute them in the equation
∵ -2 = a(0 - 2)² + 2
∴ -2 = a(-2)² + 2
∴ -2 = a(4) + 2
∴ -2 = 4a + 2
→ Subtract 2 from both sides
∴ -4 = 4a
→ Divide both sides by 4
∴ -1 = a
→ Substitute it in the equation above
∴ y = -1(x - 2)² + 2
∴ y = -(x - 2)² + 2
∴ The vertex form equation for the given graph is y = -(x - 2)² + 2
Is triangle ABC a right triangle?
no, because none of the slopes of the line segments forming the legs are opposite reciprocals
no, because none of the slopes of the line segments forming the legs are equal
yes, because BC is perpendicular to AC
yes, because AB is perpendicular to AC
Answers
Answer:
yes because BC is perpendicular to AC
Step-by-step explanation:
BC slope is 6/2 which is 3
AC slope is -3/9 which reduces to -1/3
3 and -1/3 are opposite reciprocals and therefore the lines are perpendicular
Answer:
C yes, because BC is perpendicular to AC
Step-by-step explanation:
If the lengths of two sides of a right triangle are 5 and 12 units, what is the least possible length, in units, of the third side? Express your answer in simplest radical form.
Answers
(leg)^2 + (leg)^2 = (hypotenuse)^2
(5)^2 + (12)^2 = (h)^2
25 + 144 = (h)^2
169 = (h)^2
sqrt{169} = sqrt{(h)^2}
-13 = h
13 = h
We reject h = -13 because length is a distance and distance cannot be negative.
So, h = 13 units is the answer.

The formula B = 2HL can be used to determine the number of bricks, B, needed to build a wall of height H and length L.
What is the height of a wall built 28 feet long and requires 1736 bricks?
Answers
9514 1404 393
Answer:
31 feet
Step-by-step explanation:
Fill in the given numbers and solve for the missing value.
B = 2HL
1736 = 2H(28)
1736/56 = H = 31
The wall is 31 feet high.
Answer:
N = 7·L·H
2310 = 7·30·H
2310 = 210·H (now, divide both sides by 210)
2310 ÷ 210 = 11
H = 11 feet

Step-by-step explanation:
Nate tosses a ball up a hill for his dog to chase. The path of the ball is modeled by the function y=- 1 4 x^ 2 + 33 5 x. , where x is the ball's horizontal distance from Nate in feet and y is the ball's height in feet. The hill is modeled by the line y = 1/5 * x . How far does the ball travel horizontally before it hits the ground? (in feet, round to tenth place if necessary )
Answers
Answer:
The ball's horizontal distance from Nate in feet when the ball hits the ground is 25.6 feet
Step-by-step explanation:
The given equation that represents the path of the ball is y = -1/4·x² + 33/5·x
The equation of the that models the hill is y = 1/5 × x = 1/5·x
Where, x represents the ball's horizontal distance from Nate in feet and y represents the ball's height in feet
To find the point of contact, we equate both equations to find the common solutions as follows;
-1/4·x² + 33/5·x = 1/5·x
-1/4·x² + 33/5·x - 1/5·x = -1/4·x² + 32/5·x = 0
-1/4·x² + 32/5·x = 0
0 = 1/4·x² - 32/5·x
1/4·x² - 32/5·x = 0
x·(1/4·x - 32/5) = 0
x = 0 or 1/4·x - 32/5, and x = 32/5 × 4 = 128/5 = 25.6
The ball's horizontal distance from Nate in feet = x = 25.6 feet
The ball's horizontal distance from Nate in feet when the ball hits the ground is 25.6 feet.

Answer:

Step-by-step explanation:
It can be useful to graph the equation and plot the points. Alternatively, you can evaluate the equation at the offered points.
Right away, you will notice that x must be even if y is to be an integer. The first point is the y-intercept, which the equation tells you is (0, 5). Then the only remaining candidate point is (10, 0), which also satisfies the equation:
0 = (-1/2)(10) +5 = -5 +5
