fill in the table below by finding the value of the function y = -2x + 3 at each of the inputs x = -1, x = 0, and x = 1.
Answer:
y=-2(-1)+3 y=5
y= -2(0)+3 y=3
y= -2(1)+3 y=1
0 > 3x - 3 - 6
what is answer
Answer:
x < 3
(*￣3￣)╭
Answer:
The answer is x < 3.
Step-by-step explanation:
1) Simplify 3x - 3 - 6 to 3x - 9.
[tex]0 > 3x - 9[/tex]
2) Add 9 to both sides.
[tex]9 > 3x[/tex]
3) Divide both sides by 3.
[tex] \frac{9}{3} > x[/tex]
4) Simplify 9/3 to 3.
[tex]3 > x[/tex]
5) Switch sides .
[tex]x < 3[/tex]
Therefor, the answer is x < 3.
Find the value of x. Round to the nearest tenth.
Use this to find the value of x: tan (x) = 4/3
Using tan(x) = 4/3
X = arctan(4/3)
X = 53.1 degrees
Answer:
Step-by-step explanation:
tan x = 4/3
tan x=1.333333
divide both sides by tan
x=1.33333/tan
x=tan inverse of 1.33333
x=53.130
x=53.13 to the nearest tenth

The measure of one base angle of an isosceles triangle is 35 degrees. What is the measure of the vertex angle?
Answer:
110 degrees
Step-by-step explanation:
The measures of the two base angles of an isosceles triangle are the same so 180 - 2(35) = 110 which is the vertex angle.

Answer: T(x) = 18x + 65
Step-by-step explanation:
T(x) = A(x) + B(x)
T(x) = 10x + 50 + 8x + 15 [Plug in the number for A(x) and B(x)]
T(x) = 10x + 8x+ 50 + 15
T(x) = 18x + 65

find the particular solution to the exact differentiable equation dy/dx=(2e^x)-cosx passing through the point (0,3)
Answer:
y = 2eˣ - sin x + 1
Step-by-step explanation:
dy/dx = 2eˣ - cos x
(0, 3)
Integrate dy/dx to find the original function.
y = 2eˣ - sin x + CSolve for C by substituting the point given.
3 = 2e⁰ - sin(0) + C 3 = 2 - 0 + C 1 = CNow we can substitute C into the original function.
y = 2eˣ - sin x + 1This is the particular, or explicit, solution to the differentiable equation.

Segments AB,DC, and EC intersect at point C. Angle DCE measures 148. Find the value
Answer:
x = 16°
Step-by-step explanation:
We can see that AB is a straight line. The sum of angles on a straight line adds up to 180°
∠ACD + ∠DCE + ∠ECD = 180° (sum of angles on a straight line)
∠ACD = x, ∠DCE = 148, ∠ECD = x
substituting the respected values for the angles gives:
x + 148 + x = 180
2x + 148 = 180
subtracting 148 from both sides:
2x + 148 - 148 = 180 - 148
2x = 32
Dividing both sides by 2, to get x:
2x/2 = 32/2
x = 16°

The ratio of girls to boys in a swimming club was 2 : 4. There were 14 girls. How many total members were there in the club?
Answer:
42
Step-by-step explanation:
the ratio 2:4 can be reduced to 1:2,
where the number of girls corresponds to the 1 and the number of boys corresponds to the 2.
If there are 14 girls, then there must be 28 boys (14 x 2 = 28).
Now to get the total number we need to add the total number of boys and girls together.
So 14 + 28 = 42
Hope it helps :)
Answer:
32
Step-by-step explanation:
14 + 28 = 32
2 x 7 = 14

What should be added to both sides of the equation below to complete the square?
x?
+ 6x = -8
O-4
O-2
O-9
09
Answer:
Step-by-step explanation:
x² + 6x = 8
Coefficient of the x term: 6
Divide it in half: 3
Square it: 3²
Add 3² to both sides of the equation to complete the square and keep the equation balanced:
x² + 6x + 3² = 8 + 3²
(x+3)² = 17
