Find the equation of the line that goes through the point (4, -3) and has a slope of 0.
Answer:
y = - 3
Step-by-step explanation:
A line with a slope of 0 is horizontal and parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (4, - 3 ) with y- coordinate - 3, then
y = - 3 ← equation of line
Paul and Tammy went out to dinner and the total of their meals was $37.85. Paul spent $12.55 less than what Tammy spent. How much did Paul spend?
Answer:
Paul spent $12.65
Step-by-step explanation:
Create a system of equations where p is how much Paul spent and t is how much Tammy spent.
p + t = 37.85
p = t - 12.55
Solve by substitution:
p + t = 37.85
(t - 12.55) + t = 37.85
2t - 12.55 = 37.85
2t = 50.4
t = 25.2
Find how much Paul spent by plugging in 25.5 as t into p = t - 12.55
p = t - 12.55
p = 25.2 - 12.55
p = 12.65
So, Paul spent $12.65

Answer:
80
Step-by-step explanation:
x + (2x-60) = 180
combine like terms
3x - 60 =180
add 60 to both sides
3x = 240
divide both sides by 3
x = 80
plug it back in to check
80 + (2(80) - 60 = 180
80 + (160 -60) = 180
80 + (100) = 180
180 = 180
Look at the right-angled triangle ABC.
32°
The square fits exactly inside the triangle.
Work out the sizes of angles x, y and z.
Answer:
∠x = 90°
∠y = 58°
∠z = 32°
Step-by-step explanation:
he dimensions of the angles given are;
∠B = 32°
Whereby ΔABC is a right-angled triangle, and the square fits at angle A, we have;
∠A = 90°
∠B + ∠C = 90° which gives
32° + ∠C = 90°
∠C = 58°
∠x + Interior angle of the square = 180° (Sum of angles on a straight line)
∠x + 90° = 180°
∠x = 90°
∠x + ∠y + 32° = 180° (Sum of angles in a triangle)
90° + ∠y + 32° = 180°
∠y = 180 - 90° - 32° = 58°
∠y + ∠z + Interior angle of the square = 180° (Sum of angles on a straight line)
58° + ∠z +90° = 180°
∴ ∠z = 32°
∠x = 90°
∠y = 58°
∠z = 32°

From the figure below, Prove that segment JP is parallel to segment LM.
1. Slope of JP
(Write answer as a fraction. Ex 5/6. No spaces)
2. Slope of LM
(Write answer as a fraction. Ex 5/6. No spaces)
3. The two segments are Parallel or Perpendicular?
(spell out the correct
answer. No caps needed)
Answer:
1. Slope of JP is 2/3
2. Slope of LM is 2/3
3. The two segments are Parallel.
Step-by-step explanation:
1. Slope is easy to find out if you have a graph. Rise/Run is how I remember it. The only thing you have to do is count. If you count from P to J Down 2 unites, and left 3 units you get your answer.
2. Slope LM is the exact same as Slope PJ because they are parallel.
3They are parallel because they both have the same slope.
The length of each of the legs of an isosceles triangle is represented by the
expression 6x – 2 inches. The length of the base of the isosceles triangle is
represented by the expression 3x + 1 inches. The perimeter of the isosceles
triangle is 42 inches. What is the length of the base?
Answer:
10 inches
Step-by-step explanation:
6x-2+6x-2+3x+1=42
12x-4+3x+1=42
15x-3=42
15x=45
x=3
Plug x=3 into 3x+1
3*3+1
9+1=10
Length of base is 10 inches
A puppy’s weight increased from 12 pounds to 15 pounds. By what percentage did the puppy’s weight increase?
=======================================================
Work Shown:
A = old value = 12 pounds
B = new value = 15 pounds
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (15-12)/12 ] * 100%
C = (3/12)*100%
C = 0.25*100%
C = 25%
The positive C value indicates a percent increase
So effectively, we find the difference or change in weight (B-A) and divide it over the original weight (A). That leads to 0.25 which converts to 25%
Note that,
25% of 12 = 0.25*12 = 3
This says that the puppy gained 3 pounds, which is the value of B-A
Since the puppy gained 3 pounds, the new weight is 12+3 = 15 pounds
-----------
As an alternative, we could divide the two values B over A to find that
B/A = 15/12 = 1.25
Then subtract 1 from this result: 1.25 - 1 = 0.25 = 25%

Isabella is bouncing a rubber ball that has a density of 1.5 g/cm3 . The rubber ball has a volume of 113 cm³.
What is the mass of the rubber ball?
Answer:
The mass of the rubber ball is 169.5g
Step-by-step explanation:
we know that
The density is equal to the ratio of the mass by the volume
D=m/V
Solve for m
m=D*V
In this problem we have
V=113 cm^3
D=1.5 g/cm^3
substitute
m.1.5*113=169.5g

The ordered pairs (20, -29.5),(21, -31), and (22, -32.5) are points on the graph of a linear equation. Which
of the following graphs show all of the ordered pairs in the solution set of this linear equation?
The graph that contains the 3 points is the bottom right graph.
Which line contains the 3 points?We want to see which of the graphs contains the 3 ordered pairs:
(20, -29.5),(21, -31), and (22, -32.5)
So we just need to look at the graphs and see which one has these points, notice that as x increases y decreases, so we have a decreasing line.
The slope of the decreasing line is:
a = (-31 + 29.5)/(21 - 20) = -1.5
The graph with this slope is the last one (bottom right, the other decreasing line has a slope of -1). So that is the correct option.
