What is the slope?
Answers
Step-by-step explanation:
given,
points = (7,0) & (3,6)
we know,
slope = y_2 - y_1 / x_2 - x_1
now,
→ 6 - 0/3-7
→ 6/-4
→ -1.5 or 3/-2
therefore , slope of line is -1.5 OR In the form of fraction it is 3/-2.

What is an equation of the line that passes through the point (−1,−3) and is parallel to the line 6x-y=1?
Answers
Answer:
y = 6x + 3
Step-by-step explanation:
6x - y = 1
6x -1 = y
Slope = 6
Point (-1,-3)
y-intercept = -3 - (6)(-1)
= -3 + 6 = 3
y = 6x + 3
Which equation reveals the minimum or the maximum value of f(x) without changing the form of the equation?
A f(x) = (x – 1)2 + 2
6 f(x) = x2 – 2 – x + 1
© f(x) = x2 – 2x + 1
D f(x)= (x - 1)(x - 1)
Answers
Answer:
A): f(x) = (x – 1)² + 2
Step-by-step explanation:
The quadratic function, f(x) = (x – 1)² + 2 is in vertex form: y = a(x - h)² + k, where:
The vertex of the graph is (h,k).The value of a determines whether the graph opens up or down. If a is positive, the graph opens up and the vertex is its minimum point. If a is negative, then the graph opens down, and the vertex is its maximum point. The value of h determines how far left or right the parent function is translated. The value of k determines how far up or down the parent function is translated.The function, f(x) = (x – 1)² + 2, provides the pertinent information that allows us to determine the parabola's minimum value, as the value of a is a positive, which implies that the parabola is upward facing, and the vertex, (1, 2) is the minimum point.

The three inside angles need to equal 170 when added together.
When two sides are the same which is shown by the little lines through the sides the two bottom angles are the same.
1. X = 170-80-80 = 20
2. X = 180-75-75 = 30
3. X = 180-70 = 110/2 = 55
Step-by-step explanation:
1) x+80°+80°=180°
x=180°-160°
x=20°.
2) as it is a isosceles triangle, y =75°.
x+75°+75°=180°
x=180°-150°
x=30°.
3) 2x+70°=180°
2x=110°
x=55°.
hope all these helps you.
A passenger train leaves the train depot 2 hours after a freight train left the same depot. The freight train is traveling 20mph slower than the passenger train. Find the rate of each train, if the passenger train overtakes the freight train in threehours.
Answers
Answer:
50 (mph) = rate of passenger train
Step-by-step explanation:
Let the rate of the freight train = R
Let the rate of the passenger train be R + 30
The freight train has been traveling for 2 + 3 = 5 hours
And the passenger train has been traveling for 3 hours
And they have traveled the same distance when the passenger train overtakes the freight train
So using rate * time = distance we have that
R(5) = (R + 20) 3 simplify
5R = 3R + 60 subtract 3R from both sides
2R = 60 divide both sides by 2
R = 30 (mph) = rate of freight train
R + 20 = 50 (mph) = rate of passenger train

Solve for h in terms of g and u
4u²(2u²) /g = -2u²h -gh²/2 +h
Answers
9514 1404 393
Answer:
h = (1 -2u² ± √(1 -4u²-12u⁴))/g
Step-by-step explanation:
This is a quadratic in h, so there are two solutions.
Written in standard form, the given equation is ...
(-g/2)h² +(1-2u²)h -8u⁴/g = 0
The quadratic formula tells you the solution for h is ...
h = (-(1 -2u²) ±√((1 -2u²) -4(-g/2)(-8u⁴/g)))/(2(-g/2))
h = (2u² -1 ± √(4u⁴ -4u² +1 -16u⁴))/-g . . . . . simplify
h = (1 -2u² ± √(1 -4u²-12u⁴))/g . . . . . . . . collect terms

Step-by-step explanation:
7b = 84
We can break down 7b as 7 x b
7 x b = 84
We divide both sides by 7:
7 x b ÷ 7 = 84 ÷ 7
b = 12

The perimeter of a rectangle is 28cm it’s length is more than 10cm more than it’s widith which equation can be used to find the dimensions
Answers
P = 2((10 + x) + x)
The perimeter of a rectangle is the sum of the length and width multiplied by 2
P = 2(l + w)
[to simplify the expression]
P = 2 × (l + w)
[using x to represent the width]
w = x
l = x + 10
P = 2 × ((10 + x) + x)
P = 2((10 + x) + x)
