Substitute y = 2x - 15 to the second equation:
4x + 3(2x - 15) = -5 use distributive property
4x + (3)(2x) + (3)(-15) = -5
4x + 6x - 45 = -5 add 45 to both sides
10x = 40 divide both sides by 10
x = 4
Substitute the value of x to the equation y = 2x - 15:
y = 2(4) - 15 = 8 - 15 = -7
<h3>Answer: (4, -7)</h3>
Well
You want to calculate the interest on $1000 at 3.5% interest per month after 3 year(s).
The formula we'll use for this is the simple interest formula, or:
Where: P is the principal amount, $1000.00.
r is the interest rate, 3.5% per month, or in decimal form, 3.5/100=0.035.
t is the time involved, 3....year(s) time periods.
Since your interest rate is "per month" and you gave your time interval in "year(s)" we need to convert your time interval into "month" as well.
Do this by multiplying your time, 3 year(s), by 12, since there's 12 months in 1 year.
So, t is 36....month time periods.
To find the simple interest, we multiply 1000 × 0.035 × 36 to get that:
The interest is: $1260.00

Answer: The height of a triangle is the perpendicular segment that joins the base with its opposite vertex.
Step-by-step explanation:
The base can be any side of the triangle.
Answer:
x+6=y and 3x=12
Step-by-step explanation:
Let x be the distance traveled by Bryan and let y be the distance traveled by Sam then the first equation would be:
x+6=y (x plus 6 is equal to y, Bryan's distance plus 6 is equal to Sam's distance) and the second one is:
3x=12 (3 times x is 12, 3 times the distance travelled by Bryan is 12)
So our statements/equations are:
x+6=y and
3x=12 (we dont write this as x=4 as it asks us to give the statements we got from the information given, we only start simplifying once it tells us to solve)
The number -5 would go to the left of a number scale. Typically because all negatives move to the left of zero on the number scale.
