3(2c + 5) = 39
What is the answer ?
Answer:
c=1
Step-by-step explanation:
Simplifying
3 + 2c = 5
Solving
3 + 2c = 5
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 2c = 5 + -3
Combine like terms: 3 + -3 = 0
0 + 2c = 5 + -3
2c = 5 + -3
Combine like terms: 5 + -3 = 2
2c = 2
Divide each side by '2'.
c = 1
Simplifying
c = 1
Answer:
= 4
Step-by-step explanation:
Subtract 15 from both sides of the equation
6+15=39
6+15−15=39 − 5
Simplify
6=24
Divide both sides of the equation by the same term
(6=24)/6
Simplify
=4
Order from least to greatest.
68%, 0.687, 20
Answer:
20, 68%, 0.687
Step-by-step explanation:
If 20 were to be a percentage, then it'll be less than 68% and 0.687. Since the 7 in 0.687 is greater than 5, you would round up when the question says so. 0.687 is greater than 68%; if you move the decimal 2 times to the right, then 0.687 would be 68.7%. Therefore the order from least to greatest is 20, 68%, 0.687.

Can someone tell me why is nobody helping me with my question I be POSTING 4 TIMES PLEASE YALL Help me please
Answer:
x = 4
y = 5
Step-by-step explanation:
4x = x + 12
^(subtract x from both sides)^
3x = 12
^(divide both sides by 3)^
x = 4
3y = 15
(divide both sides by 3)
y = 5
Angles 1 and 2 are supplementary. If angle 1 measures (2x +2)°, and angle 2 measures (x - 5)° what is the measure of each angle?
Answer:
angle 1 is = 124 angle 2 is = 56
Step-by-step explanation:
supplementary angles always add up to 180 so you can set up the equation (2x+2)+(x-5)=180 to find x. After solving you get x = 61 and then once you have x you plug it into the 2 equations you got for the angles to solve for 1 and 2.

slope: -25, y-intercept=0
slope = -1/4, y-intercept = 50
slope = 1/2, y-intercept = 25
I need help with the question!!
Answer:
slope = -1/4, y-intercept = 50
Step-by-step explanation:
x=0 y=50
x=100 y= 25
y= mx+b
b= 50
25= 100 m +50
100m = - 25
m= -1/4
where m is the slope and b is the y intercept

ok sweetheart so basicaly what u do is...
Sample Response: Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator
Answer:
This is what it says to include in your response..." Each base has a negative exponent" and "Both powers should be in the denominator".
Step-by-step explanation:
This is the Exact sample response,
Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator.
Roy has $30 in a savings account. The interest rate is 10% per year and is not
compounded. How much will he have in 4 years?
Answer:
$43.92
Step-by-step explanation:
1st year:
30 x 10% = 3
30 + 3 = 33
2nd year:
33 x 10% = 3.3
33 + 3.3 = 36.3
3rd year:
36.3 x 10% = 3.63
36.3 + 3.63 = 39.93
4th year:
39.93 x 10% = 3.99
39.93 + 3.99 = 43.92
Which conic section is represented by the following equation?
5x^2 – x + 5y^2 – 3y + 4 = 0
circle
ellipse
parabola
hyperbola
Answer:
3 rd one
Step-by-step explanation:
The conic section represented by the given equation is Circle.
What is Circle?Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.
Standard form of a circle is,
(x - h)² + (y - k)² = r²
where, (h, k) is the center of the circle and r is the radius of the circle.
Expanding, we get,
x² - 2hx + h² + y² - 2ky + k² = r²
x² - 2hx + y² - 2ky + (h² + k² - r²) = 0
The given equation is,
5x² – x + 5y² – 3y + 4 = 0
This is same as the standard form of the circle.
Hence the given equation is that of a circle.

Write a linear function f with the values f(3)=2 and f(0)=6
Answer:
for f(3)=2 is y=(2/3)x
Step-by-step explanation:
y=ax
and plug x and y into the parent function.
Answer:
f(x) = -⁴/₃x + 6Step-by-step explanation:
f(0) = 6 means y-intercept b = 6
So we have:
f(x) = mx + 6 and f(3) = 2
So:
2 = m×3 + 6
3m + 6 = 2
3m = 2 - 6
3m = -4
m = -⁴/₃
Therefore the function:
f(x) = -⁴/₃x + 6Help me ??????????????????
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
(h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = - 2x² - 12x - 16
To complete the square the coefficient of the x² term must be 1
Factor out - 2 from - 2x² - 12x
f(x) = - 2(x² + 6x) - 16
add/ subtract ( half the coefficient of the x- term )² to x² + 6x
f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16
= - 2(x + 3)² + 18 - 16
= - 2(x + 3)² + 2 ; y = 2
