Step-by-step explanation:
Area of a triangle: .5(b*h)
which means that
.5(4(x-1)*(2x+5))=30
mulitply the two equations
(4x-4)(2x+5) = 8x²+12x-20
distribute the 1/2
.5(8x²+12x-20)
4x²+6x-10 = 30
divide both sides by 2
2x²+3x-5= 15
move everything to one side
2x²+3x-20=0
not sure if you need to solve it but x= 2.5 or x= -4

A bag contains yellow balls, pink balls and green balls only.
The ratio yellow balls : pink balls : green balls = 7:3:5.
There are 42 yellow balls in the bag.
Work out the total number of balls in the bag.
What’s the answer
Answers
Answer:
90
Step-by-step explanation:
M1 for ( ) 42/7 [x(7+3+5)] soi by 6
=90
Assuming there are only 42 yellow balls in the bag. The total number of balls in the bag is 90 balls.
Total number of ballsFormulate
42×(3+5+7)÷7
Reduce the fraction
42÷7×(3+5+7)
6×(3+5+7)
Hence:
Total number of balls=6×15
Total number of balls=90 balls
Inconclusion the total number of balls in the bag is 90 balls.

If the initial point of a vector V is (-1,2) and the terminal point of vector V is (-4,5) then the component form of the vector is
Answers
Answer:
The components form of the vector is:
V = [-3,3]
Step-by-step explanation:
The initial point is V(i) = (-1,2) and the final point V(f) = (-4,5). If we want to get the components form, we just need to subtract each component of the points.
a = -4-(-1) = -4+1 = -3
b = 5-2 = 5-2 = 3
a represents the x-componet and b the y-component of the vector.
Therefore, the components form of the vector is:
V = [a,b]
V = [-3,3]

Jed is pouring water into a container at a constant rate of 8.25 ounces per second. There are already 24.75 ounces of water in a container. How many
ounces of water will be in the container after 5 seconds?
29.75 ounces
33 ounces
49.5 ounces
66 ounces
Answers
Answer:
66 ounces
Step-by-step explanation:
24.75 + (8.25 x 5) = 24.75 + 41.25 = 66
Answer:
66 ounces
Step-by-step explanation:
To solve this, set up a fraction. Let "x" be the ounces of water after 5 seconds.
[tex]\frac{8.25}{1}=\frac{x}{5}[/tex]
Step 1: Switch sides
[tex]\frac{x}{5}=\frac{8.25}{1}[/tex]
Step 2: Apply rule: [tex]\frac{a}{1}=a[/tex]
[tex]\frac{x}{5}=8.25[/tex]
Step 3: Multiply both sides by 5
[tex]\frac{5x}{5}=8.25\cdot \:5[/tex]
Step 4: Simplify
[tex]x=41.25[/tex]
Now we have found the ounces of water in the container after 5 seconds, but already, there are 24.75 ounces before the ounces after 5 seconds. So to find the total add the given data to the found result
Step 1: Add 24.75 to 41.25
[tex]24.75 + 41.25 = 66[/tex]
Therefore, there are 66 ounces after 5 seconds when 24.75 ounces are already in the container.

Write an equation of a line that passes through the point (2.3) and is parallel to the line y = 3/2 x + 5
Answers
Answer:
y = (3/2)x
Step-by-step explanation:
Parallel lines have the same slope only the constant in the slope intercept equation changes.
to find the new slope intercept, b, plug in the point (2, 3) and m = 3/2
3 = (3/2)(2) + b
3 = 3 + b
b = 0
The parallel line is
