Determine the number of solutions you will have for the system 4y + x = 16 and y = 4 – x.

Equaling both equations, it is found that the **correct option** that states the **number of solutions **you will have for the system is:

The **equations **are:

[tex]4y + x = 16 \rightarrow x = 16 - 4y[/tex]

[tex]y = 4 - x \rightarrow x = 4 - y[/tex]

**Equaling **both equations **for x,** we have that:

[tex]16 - 4y = 4 - y[/tex]

[tex]3y = 12[/tex]

[tex]y = \frac{12}{3}[/tex]

[tex]y = 4[/tex]

[tex]x = 4 - y = 4 - y = 0[/tex]

Hence, the system has **one solution**, which is (0,4), and **option d **is correct.

**Answer:**

A

**Step-by-step explanation:**

The answer is A because is it asking for a 3 in the hundredths place of the difference. Difference means subtraction. And you can find the hundredth spot in the second place over from the decimal

(ex. 1.23, hundredth place is a 3)

So then you do the math and find the differences.

14.56-9.33=5.23, which has a 3 in the hundredth place.

3x+5y−7x+6=12

The** value of x **from the equation is** x = (5y - 6)/4**

**Given** the equation 3x+5y−7x+6=12

collect the l**ike terms;**

Johnny Inneger saved $100 to buy a guitar. Then he bought one for $80. Johnny lost patience learning to play it and decided to sell it to his friend Michael Michael had also saved $100 Michael really wanted the guitar, so he paid Johnny $90 for it. After johnny saw his favorite guitar player in a concert, he wanted to buy back the guitar. He bought it back from Michael for $95. Now Michael has offered Johnny 585 for the guitar. Johnny is deciding whether he will accept the offer. if he does will he have lost any money on the guitar? If so, how much?

No he hasn’t lost money he still has $15 left.

if you take the initial 100-80=20

then 20+90 is 110

take 110-95 you get 15.

if he accepts michael’s offer he will be gaining 600.

if you take the initial 100-80=20

then 20+90 is 110

For Part A

Set f(x) = 0

Factor the Quadratic

Set the factors = 0

Solve each factor for x to find your x intercepts

For Part B

You need to use the coefficients in your Quadratic

List them

a = 2 , b = -3 and c = -5

Since a is positive, your parabola opens up

Find the x coordinate of the vertex it is -b/2a

One you get the x coordinate, plug it into to your Quadratic to get f(x) your y coordinate of the vertex

For Part C

You can plot the vertex, both x intercepts on a coordinate grid

Problem Situation: Ben buys a table for $240. He also buys 6 chairs that all cost the same amount. His total cost is $720. What is the price of one chair? Use the drop-down menus to complete parts A and B below.

The price of **one chair** Ben bought is $80 and he bought 6 chairs in total.

A numerical expression is a mathematical statement written in the form of numbers and unknown **variables**. We can form numerical expressions from statements.

Given, Ben buys a table for $240. He also buys 6 chairs that all cost the same amount.

Assuming each chair costs $**x **and his total cost is $720.

∴ **240 + 6x = 720**.

6x = 720 - 240.

6x = 480.

x = 80

Recall that y = mx+b is the slope intercept form of any linear equation

m = slopeb = y interceptThe given equation has m = 4/5 as the slope. Flip the fraction to get 5/4 and then flip the sign to get -5/4

The original slope is 4/5 and the perpendicular slope is -5/4. Note how the slopes multiply to -1.

The slope for the answer is -5/4 and the y intercept for the answer is -8

Therefore, the perpendicular line is **y = (-5/4)x - 8**

Find the value of sin D rounded to the nearest hundredth, if necessary.

**Answer:**

0.22

**Step-by-step explanation:**

So in this problem, we have to find the hypotenuse first, since sine is opposite over hypotenuse.

We can do this using the pythagorean theorem (you can search it if you don't know). Or, we can just remember this as one of our pythagorean triplets (9,40,41). The last side will be 41.

We have to find the value of sin(D)
