Answer:

c = -3

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

$4(-2)=4*\frac{-c-11}{4}$

Cancel multiplied terms that are in the denominator

$4(-2)=-c-11$

Multiply the numbers

$-8=-c-11$

Add 11 to both sides of the equation

$-8+11=-c-11+11$

Simplify

$3=-c$

Divide both sides of the equation by the same term

$\frac{3}{-1}=\frac{-c}{-1}$

Simplify

$c=-3$

syeda has finished 20% of her math assignment. The assignment includes 50 problems how many problems has syeda completed?

Nostrana [21]

Answer:

10 problems

Step-by-step explanation:

This is the answer because:

1) We have to solve for what 20% of 50 is since she finished 20% of her test:

20% of 50 = 10

$\frac{2}{10}$ × $\frac{50}{1}$ = $\frac{100}{10}$ = 10

Therefore, the answer is 10 problems.

Hope this helps! :D

Answer:

See below

Step-by-step explanation:

f(x) is quadratic function and g(x) is linear (since AP in the right column).

Find the equation of the function f(x), use the points on the graph:

f(x) = ax² + bx + c

c = 5 as the y-intercept is (0, 5)
a(-1)² + b(-1) + 5 = 0 ⇒ a + 5 = b
a(5²) + b(5) + 5 = 0 ⇒ 25a + 5b + 5 = 0 ⇒ 25a + 5a + 25 + 5= 0 ⇒ a = -1 ⇒ b= 4

The function is:

f(x) = -x² + 4x + 5

Find the equation of g(x)

Find the slope of g(x):

m = (1 - 7)/(-1 + 4) = -2

Use (-4, 7) to find its equation:

y - 7 = -2(x + 4)
y = -2x + 7 - 8
y = -2x - 1

<h3>See the required comparison below</h3>

The y-intercepts:

f(x) ⇒ 5,
g(x) ⇒ -1
-5 < - 1

Values at x = 3:

f(3) = -3² + 4(3) + 5 = 8
g(3) = -2(3) - 1 = - 7
8 > 7

Average rate of change in the interval [2,5]:

f(x) ⇒ (0 - 9)/(5 - 2) = -3
g(x) ⇒ (-11 + 5)/ (5 - 2) = -2
-3 < -2

Max of function in the interval [-5, 5];

f(x) ⇒ 9, vertex of the function
g(x) ⇒ g(-5) = -2(-5) - 1 = 9, taken the least point of x as it is a decreasing function
9 = 9
