Plot and connect the points A(1,-5), B(-4,-3), C(3,-3), and find the area of the triangle it forms.
Answer:
7 square units
Step-by-step explanation:
Two of the points are on the horizontal line y = -3, so it is convenient to call that the "base" of the triangle. The length of the base is the difference in the x-coordinates of its end points:
b = 3 -(-4) = 7
The height is measured perpendicular to the base, so is the vertical distance from the line y=-3 to the third point. That distance is the difference between -3 and the y-coordinate of point A:
-3 -(-5) = 2
The triangle has a base of length 7 and a height of 2. Its area is ...
A = 1/2bh
A = 1/2(7)(2) = 7 . . . . square units
I am stuck on this question it was can you add 4+2x to get 6x
Answer:
No you can't.
Step-by-step explanation:
4 is an integer, and 2x isn't so you can't add them together. If 4 was 4x or 2x was 2, then you'd get 6, but you can't add them. Hope this helps :)

Find a line that is perpendicular to y = 2/5x-1 that goes through (3,6)
Answer:
[tex]\sf y=-\frac{5}{2}x+\frac{27}{2}[/tex]
Step-by-step explanation:
given equation:
[tex]\sf y = \frac{2}{5} x -1[/tex]
using the formula: y = mx + b
Here, we can determine 2/5 is the slope
if perpendicular: -1/m → -1/2/5 → -5/2
using the formula:
[tex]\sf y - y1 = m ( x - x1)[/tex]
[tex]\sf y - 6 = -\frac{5}{2} ( x - 3 )[/tex]
[tex]\sf y - 6 = -\frac{5}{2} x - \frac{15}{2}[/tex]
[tex]\sf y = -\frac{5}{2} x + \frac{15}{2} +6[/tex]

Draw a line representing the "rise" and a line representing the "run" of the line. State
the slope of the line in simplest form.
Solution:
Rise and run stated in graph below.
To find the slope of the line, we need to use the formula "Rise/Run".
Looking at the graph, we can tell that
The rise is 3 unitsThe run is 12 unitsWhen rise/run used:
Rise/Run = 3/12 = 1/4Thus, the slope is 1/4.

The Equation of L1, is y=5x+1
The Equation of L2, is 2y-10x+3=0
Show that these two lines are parallel
Parallel lines are lines that have equal slope
It is true that the two lines are parallel
How to show that the lines are parallel
The equations of the two lines are given as:
y = 5x + 1 and 2y - 10x + 3 = 0
Both equations are linear equations, and a linear equation is represented as:
y = mx + b
Where m represents the slope.
For equation L1, the slope is:
m = 5
For equation L2, we have:
[tex]2y - 10x + 3 = 0[/tex]
Divide through by 2
[tex]y - 5x + 1.5 = 0[/tex]
Make y the subject
[tex]y = 5x - 1.5[/tex]
This means that the slope of equation L2 is also 5
When the slopes are equal, then the lines are parallel
Hence, the two lines are parallel

Hanna must spend no more than $40 at the bookstore. She is planning on buying
a book for $16 and some magazines, m, for $4 each. Which inequality represents
Hanna's situation?
a.) 4m + 16 > 40
b.) 4m + 16 < 40
c.) 16m + 4 > 40
d.) 16m + 4 < 40
Answer:4m+16<40
Step-by-step explanation:
m=magazines
She's planning on buying a number of magazines (m) with a cost of $4 so it would be "4m".
She's planning on buying a book for $16 also so
4m+16
She wants to have a price all under 40 so
4m+16 < 40
Prepare an amortization schedule for a three-year loan of $57,000. The interest rate is 8 percent per year, and the loan calls for equal annual payments. How much interest is paid in the third year? How much total interest is paid over the life of the loan?
To repay this loan in three years we must make annual payments of $23,560.
How to calculate how much we should pay annually?To calculate the payments that we must make each year, taking into account the 8% interest, we must carry out the following operations:
$57,000 ÷ 3 = 19,000To calculate the interest equivalent to 8%:
$57,000 ÷ 100 = $570$570 × 8% = $4,560So, to calculate the total per year that we must pay, we must add both values:
$19,000 + $4,560 = $23,560Finally, to know how much we pay in total for the interest on the loan, we multiply the value of the interest by the years that the loan lasted:
$4,560 × 3 = $13,680
