1 answer:

5 0

Answer:In the equation y = mx + b for a straight line, the number m is called the slope of the line. Let x = 0, then y = m • 0 + b, so y = b. The number b is the coordinate on the y-axis where the graph crosses the y-axi

A train travels at 100 milers per hour. An equation can be written that compares the time (t) with the distance (d). Define the

Alenkasestr [34]

Answer:

The domain is t ≥ 0

The range is D ≥ 0

Step-by-step explanation:

$rate = \frac{distance}{time}$

D(t) = 100t + d₀

t is the time measured in hours.

d₀ is the initial position of the train.

We can assume the distance they go is not negative so...

The domain is t ≥ 0

The range is D ≥ 0

$\displaystyle\\(x-4)^2=49\\\\(x-4)^2-49=0\\\\(x-4)^2-7^2=0\\\\(x-4-7)(x-4+7)=0\\\\(x-11)(x+3)=0\\\\x-11 = 0~~~\text{or}~~~x+3=0\\\\x-11=0~~~\implies~~~\boxed{x_1=11}\\\\x+3=0~~~\implies~~~\boxed{x_2=-3}\\\\\boxed{\bf The~solutions~are:~~x =11~~\text{or}~~x =-3}$

Ricardo spends 8/9 hr. reading the paper. He spends 1/4 of the time reading world news and splits the remaining time equally bet

lapo4ka [179]

Total time spent reading is = 8/9 hour

He spends 1/4 of the time reading world news. That is = 1/4 * 8/9 = 2/9 hour

Splits the remaining time equally. Remaining time = 8/9 - 2/9 = 6/9

Splitting it equally = 6/9 divided by 2 = 6/9 * 1/2 = 3/9 = 1/3

Time spent reading comic is = 1/3 hour

I hope this helps.

The distance in kilometers in scientific notation $2.03 \times 10^3 km$

<h3>Scale factors</h3>

Scale factors are values or constants multiplied with a variable

If Alvin and Simon raced a distance of $2.9 \times 10^2$ kilometers and they need to race 7 times that distance in a kilometer, the distance traveled will be:

Distance travelled = $7(2.9 \times 10^2)$
Distance travelled = $2.03 \times 10^3 km$

Hence the distance in kilometers in scientific notation $2.03 \times 10^3 km$
