dimulka [17.4K]3 years ago
4 0

Answer:

5

Step-by-step explanation:

Subtract 1 from both sides. The equation becomes 2.5d + 6.25 = 3.75d

Subtract 2.5d from both sides. The equation becomes 6.25 = 1.25d

Divide 1.25 from both sides. You get 5 = d

How do I find the domain n range of this graph​
motikmotik

Domain = {-3, 2}

Range = All real numbers

We can represent the range in interval notation as (-\infty, \infty) which is basically saying -\infty < y < \infty. The range is all real numbers due to the arrows meaning the graph extends up and down forever. So any y value is possible.

Notice with the domain we only have 2 valid x values -3 and 2. No other x values are allowed. Normally we use an interval of some kind to set up the domain, but we only have a set of values instead. The curly braces indicate "set".

Write the slope intercept form of the equation through the given point with the given slope.
Sholpan [36]

Answer:

y = 3x - 4

Step-by-step explanation:

With the slope and a point, I can make an incomplete slope-intercept equation and solve for the y-intercept.

y=3x+b\\\\2=3(2)+b\\\\2=6+b\\\\2-6=6-6+b\\\\-4=b

The equation is:

y=3x-4

Hope this helps!
