Answer:

-5 = x

Step-by-step explanation:

7(4x + 9) - 10 = -87 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: + \: 10 \: \: \: \: + 10 \\ \\ \frac{7(4x + 9)}{7} = -\frac{77}{7} \\ \\ 4x + 9 = -11 \\ \: \: \: \: \: \: -\: 9 \: \: \: \: \: - \: 9 \\ \\ \frac{4x}{4} = -\frac{20}{4} \\ \\ x = -5

** The above answer is written in reverse, which is the exact same result.

I am joyous to assist you anytime.

Use the functions f(x) = 4x − 5 and g(x) = 3x + 9 to complete the function operations listed below.
JulijaS [17]
A:

(f+g)(x)=f(x)+g(x)

(f+g)(x)=4x-5+3x+9

(f+g)(x)=7x+4

B:

(f•g)(x)=f(x)•g(x)

(f•g)(x)=(4x-5)(3x+9)

(f•g)(x)=12x^2-15x+36x-45

(f•g)(x)=12x^2+21x-45

C:

(f○g)(x)=f(g(x))

(f○g)(x)=4(3x+9)-5

(f○g)(x)=12x+36-5

(f○g)(x)=12x+31

A the slope of f(x) is greater than the slope of g(x)
Komok [63]

To find the slope of g(x), use the slope formula(m):

m=\frac{y_2-y_1}{x_2-x_1}        And plug in two points, I will use:

(0, 2) = (x₁, y₁)

(5, 4) = (x₂, y₂)

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{4-2}{5-0}

m=\frac{2}{5}

You could do the same to find f(x) by finding two points and using the slope formula, or you could use this to tell visibly:

m=\frac{rise}{run}

Rise is the number of units you go up(+) or down(-) from each distinguished point

Run is the number of units you go to the right from each distinguished point

If you look at the graph, you can see the points (0, -1) and (3, 1). From each point, you go up 2 units and to the right 3 units (you can make sure by using another point). So the slope of f(x) is  \frac{2}{3}

Whichever line looks more vertical(and is positive) has the greater slope. So the slope of f(x) is greater than the slope of g(x). The answer is option A

Mindy and Troy combined ate 99 pieces of the wedding cake. Mindy ate 3 pieces of cake and Troy had 1/4 of the total cake.
Allushta [10]

It doesn't give the entire question,  Do they want to know how many pieces were in the total cake?  If so, I think it would be 384.  You subtract the 3 pieces that Mindy ate and that leaves 96 that Tony had which was supposed to be 1/4 of the cake.  Dividing the cake into 4 sections of 96 and multiplying would give you 384.


If they want to know how many slices of cake were left after Tony ate the fourth (96 slices), it would be 288
