Answer:
<u>Slope = 3</u>
Step-by-step explanation:
The slope is the Rise/Run
Given the two points (-1,-4) and (2,5) we can calculate both the Rise and the Run:
Rise = (5 - (-4)) = 9
Run = (2 - (-1)) = 3
Slope is Rise/Run
(9/30) = 3
It is the "m" in y = mx + b
The actual equation is y = 3x + 1. Use one of the 2 points and solve for b to find that it equals -1.
y = 3x - 1 for (2,5)

Step-by-step explanation:
Answer:
The value of y = 70°
Step-by-step explanation:
∵ The measure of the major arc = 160 + 60 = 220°
∵ The measure of the circle is 360°
∴ The measure of the minor arc = 360 - 220 = 140°
∵ y is the angle between a chord and a tangent
∵ The chord subtended by the arc of measure 140°
∵ y is subtended by the arc of measure 140°
∵ Angle of tangent subtended by an arc,
its measure = half the measure of the subtended arc
∴ The measure of y = 1/2 the measure of the subtended arc
∴ y = 1/2 × 140 = 70°
I did my math and I think 41 minuets but are u adding or subracting
Alright, so a food truck owner samples 100 people on two separate days. There are our totals in the graph. The question is asking for how many burgers will the food truck sell, so try to focus only on the burgers, not the other food items.
On day 1, 33 people liked burgers.
On day 2, 42 people liked burgers.
33/100, and 42/100.
75 people out of 200 like burgers.
In the second part, its saying we should use 900, in place of the 200. So, what we do is divide 900 by 200, to see what we should multiply 75 by. Remember: Whatever you do to the top, you have to do to the bottom.
We get 4.5. So, 75*4.5=337.5
It's asking for a whole number, so we'd use 338. We round up because it is a .5, not a .4.
So, based on the samples, about how many burgers will the food truck sell?
338.
