1 mile = 1.6 kilometers

 multiply 40 mph by 1.6 = 64

car's rate = 64 kilometers per hour


multiply kilometers per hour by 4 = 256

 car will travel 256 kilometers in 4 hours

Ignacio earns 5 percent simple interest annually on his savings account. How much interest will he earn each month on $1250?. .
Len [333]
Find the interest earned in 1 year and divide it by 12 (number of months per year)

simple interest=principal times rate times time

so we have 1250 principal (amount invested)
rate is 5% or 0.05
time is 1 year

in 1 year, he earns 1250 times 0.05 times 1 or $62.5 per year
divide by 12
62.5/12=5.2083333333333333333333333333333
earns about $5.21 per month in interest

Identify the slope and y-intercept of the line whose equation is given. write the y-intercept as an ordered pair. y = negative 2
PSYCHO15rus [73]

The line having the equation, y = -2x + 5, has a slope = -2, and y-intercept = (0, 5). Thus, <u>option A</u> is the best choice.

The slope of a line is the tangent of the angle that the line makes with the positive side of the x-axis.

The y-intercept of a line is the point at which the line intersects the y-axis.

The standard form of a line is <u>y = mx + b</u>, where m represents the slope of the line, and b represents its y-intercept.

In the question, we are asked to identify the slope and the y-intercept of the line whose equation is y = -2x + 5.

Comparing the given equation of the line, y = -2x + 5, with the standard equation of a line, y = mx + b, we can say that,

m = -2, and b = 5.

Representing b as an ordered pair, we get (0, 5), as b represents the y-intercept which is a point on the y-axis, where the x-coordinate is always equal to zero.

Thus, we get the slope = -2, and the y-intercept = (0, 5).

The option representing the answer is <u>option A</u>.
