What is the slope and y-intercept of y = 3x – 1
Answer:
The slope is 3, and y-intercept is -1.
Step-by-step explanation:
All slope - intercept equations are written in the form y = mx + b. m represents the slope and b represents the y-intercept. Therefore, the slope is 3 and the y-intercept is -1.
the slope of the line is 3, and the y-intercept is -1
In the equation y = 3x - 1, the coefficient of x (the number multiplied by x) is 3. This coefficient represents the slope of the line.
Therefore, the slope of the line y = 3x - 1 is 3.
To find the y-intercept, we can observe that the equation is in the form y = mx + b, where b represents the y-intercept. In this case, the y-intercept is the constant term, which is -1.
Therefore, the y-intercept of the line y = 3x - 1 is -1.
In summary, the slope of the line is 3, and the y-intercept is -1. These values provide information about the steepness of the line and where it intersects the y-axis.

Actually Welcome to the Concept of the Trigonometry.
Since we know that, Cosine of an Angle is equal to Adjacent side divided by the Hypotenuse of the triangle.
Thus we get as,
Cos 45° = Adjacent / Hypotenuse
Cos 45° =
[tex] \frac{1}{ \sqrt{2} } [/tex]
so we get as,
[tex] \frac{1}{ \sqrt{2} } = \frac{20}{x} [/tex]
so the distance between the totem pole and the ems is the shadow is x, so we get a
[tex]x \: = 20 \sqrt{2} [/tex]
x = 20(1.41)
x= 28.28 metres.

Line KR bisects JKM. If mJKR = 81°, what is the mJKM?
Answer:
[tex]m\angle JKM = 162^\circ[/tex]
Step-by-step explanation:
Angle Bisector
An angle bisector is a ray that divides an angle into two congruent angles, each having a measure exactly half of the original angle.
We are given ray KR bisects angle JKM.
This means angle JKM is divided into two congruent angles JKR and RKM. We know:
[tex]m\angle JKR = 81^\circ[/tex]
Thus, the measure of angle JKM is twice the measure of JKR. Therefore:
[tex]m\angle JKM = 2*81^\circ= 162^\circ[/tex]
[tex]\mathbf{m\angle JKM = 162^\circ}[/tex]

Answer:
100, because 180 - 50 - 90 = 40
The vertical angles theorem is applied, so now angle DCE is 40
And since CE = ED, its isosceles triangle, so base angles are equal, so 40 and 40.
180 - 80 = 100 = Angle E.

There are 70 students in a school band . 40% of them are sixth graders , 20% of them are seventh graders , and the rest are eighth graders . what percentage of the band members are eighth graders?
Answer:
40% of the band members are eighth graders.
Step-by-step explanation:
There can only be a total of 100%. The problem already gives us the percentages of sixth graders and seventh graders, and it tells us that there are only eighth graders left. Subtract the sum of 40 and 20 from 100 to get your answer.
100% - (40% + 20%) = 40%

Well multiplication is the inverse of additon. And when multiplying you add the exponents.
So when dividing you subtract the exponents
-2t^2+4t+30 in vertex form
Answer:
- 2(t - 1)² + 32
Step-by-step explanation:
Given
- 2t² + 4t + 30
Use the method of completing the square to express in vertex form.
The coefficient of the t² term must be 1, so factor out - 2 from the first 2 terms.
= - 2(t² - 2t) + 30
To complete the square
add/subtract ( half the coefficient of the t- term)² to t² - 2t
= - 2(t² + 2(- 1)t + 1 - 1) + 30
= - 2(t - 1)² + 2 + 30
= - 2(t - 1)² + 32
