4x + 2y = -1
5x – 3y = 7
Answer:
4x-2y=-1 multiply by 3
5x-3y=7 multiply by 3
12x+6y=-3
10x-6y=14 add them
so =22x=11
x=1/2
5(1/2)-3y=7
2.5-3y=7 take 2.5 to the other side
-3y=4.5
y=-3/2
therefore x=1/2 and y=-3/2

What is the height of the triangular base? Show your work.
and What is the approximate amount of cardboard used to make the candy box?
Answer:
Hope it helps :)
Step-by-step explanation:
The volume of a triangular prism shaped box is 2,400 cubic centimeters.
Base of the triangle = 16cm
Sides of the triangle = 17cm
Length of the box = 20cm
Triangular prism
A triangular prism is a three-sided prism made of a triangular base and a corresponding side.
A. To find the height of the base = 3 x the volume divided by the base area = 15cm.
B. The approximate amount of card board used to make the candy box:
Using the lateral prism as the sides will be:
Lateral area = Perimeter of triangle X height of the prism
Lateral area = (16 + 17 + 17) X 20
Lateral area = 50 X 20
Lateral area = 1,000 cm2
Therefore, the answer is 1000cm2.
A row of 12 desks measures 27 feet. How many feet long is each desk? *

To buy a car, Rachel
borrowed $3,000 at
946 interest per
year for 3 years
How much money
did she have to pay
back?
Answer: (3000)*(0.09)*(4) = $1,080.00
Step-by-step explanation:
When money is borrowed, interest is charged for the use of that money over a certain period of time. The amount of interest charged depends on the amount of money borrowed, the interest rate and the length of time for which the money is borrowed.
Principal is the amount of money borrowed. The interest rate is given as a percent. Time is the length of time in years for which the money was borrowed.
Interest = Principal * Rate * Time which is also written as I = P*R*T
Principal = $3,000, Interest rate = 0.09 and Time = 4
Raquel had to pay back $3,000 in principal plus $1,080 in interest for a total of $4,080.00
(3000)*(0.09)*(4) = $1,080.00

An observer (O) spots a plane flying at a 55° angle to his horizontal line of sight. If the plane is flying at an altitude of 21,000 feet, what is the distance (x) from the plane (P) to the observer (O)? A right triangle is shown with angle O marked 55 degrees, hypotenuse marked x, and height marked 21,000 feet. 20,793 feet 25,636 feet 28,793 feet 36,585 feet.
Angle of elevation is angle measured from horizontal line to line of sight, The distance from the plane to the observer is 25,636 feet approx
What is angle of elevation?You look straight parallel to ground. But when you have to watch something high, then you take your sight up by moving your head up. The angle from horizontal line to the point where you stopped your head is called angle of elevation. See the figure where angle OPD is the angle when observer saw the plane. It is measured from the horizontal line OD.
Refer to the attached figure.
It is given that we have
Length of PD = |PD| = 21,000 feet
Angle ∠OPD = 55°
Assuming length of OP = |OP| = x feet, we get the sin ratio as
[tex]sin(55^\circ) = \dfrac{|PD|}{|OP|} = \dfrac{21000}{x}\\\\x = \dfrac{21000}{\sin(55^\circ)} \approx 25636.27 \approx 25636 \: \rm feet[/tex]
(tan 55° was calculated from online calculator)
Thus,
The distance from the plane to the observer is 25,636 feet approx.

y = 2x – 6
y = –4x + 3
Answer:
x = 3/2 | y = -3
Step-by-step explanation:
Given equations:
y = 2x - 6. . . .(i)y = -4x + 3. . . . (ii)Substituting from equation (i) for y:
==> 2x - 6 = -4x + 3
==> 2x + 4x = 6 + 3
==> 6x = 9
dividing both sides by 3:
==> 2x = 3
==> x = 3/2
Substituting 3/2 for x in equation (i):
==> y = 2(3/2) - 6
==> y = 3 - 6
==> y = -3
[tex] - 4x + 3 = 2x - 6 \\ 6x = - 9 \\ 2x = - 3 \\ x = - 1.5[/tex]

During the month of February, Lerato sends one SMS per day to relatives. Calculate how much this activity costs her in rands
Considering a linear function, it is found that this activity costs 240 rands.
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, we suppose that:
There is a fixed cost of 100 rands, hence b = 100.Each SMS costs 5 rands, hence m = 5.Hence, the cost of sending x messages is given by:
y = 5x + 100.
February has 28 days, hence:
y = 5(28) + 100 = 240
This activity costs 240 rands.

30
Step-by-step explanation:
All straight line equations are in the form:
[tex]y=mx+c[/tex]
Where m is the gradient and c is the y-intercept
In this equation +30 is the y-intercept
Answer:
The y-intercept is 30 in this equation
Step-by-step explanation:
This equation is in slope-intercept form.
Slope intercept form includes two things, (you can probably already guess)
It includes the slope of the line and the y-intercept
In all slope-intercept form equations the 20x would be the slope and the 30 would be the y-intercept

This is the graph of the function f(x) = k(3). The value k is a constant. Based on the graph, what is the value of k
By using the graph, we will see that k = 1.85
How to find the value of K?
Here we have the exponential function:
f(x) = k*(3)^x
And we want to find the value of k.
To find it, we need to use one point on the graph. the only one easy to read is the one for x = 3, we can see that when x = 3, f(x) = 50.
Then we have:
f(3) = 50 = k*(3)^3 = k*(3*3*3) = 27*k
Solving that for k we get:
50 = 27*k
50/27 = k = 1.85
