You seemed to have gotten the equation wrong, but don't worry I'll help you
===================================================================
First you simplify the equation
4=(-1)(-3)+b
(A negative times a negative is a positive)
4 = 3 + b
(Flip the equation)
b + 3 = 4
--------------------------------------
Then you subtract 3 from each side
b+3-3=4-3
b = 1 is your answer
===================================================================
y = -1x - 7 is wrong as well
To find the answer just add -4 on each side for y+4=-1(x-3)
y+4+-4=-x+3+-4
y = -x - 1 is the answer
To graph, plot points on Y-intercept of -1 and place another point at (-2,1)

Let T be total number of milligrams of vitamin C in our salad.

We have been given that there are s milligrams of vitamin C per milliliter of spinach, B mg per milliliter of berries, and D mg per milliliter of dressing.

Let us find how much mg of vitamin C our each ingredient of salad will have.

We have been given that a salad contains 300 milliliters of spinach, 200 ml of berries, and 42 ml of dressing.

$\text{Mg vitamin C in 300 ml spinach}=300\cdot\text{s mg}$

$\text{Mg vitamin C in 200 ml berries}=200\cdot\text{B mg}$

$\text{Mg vitamin C in 42 ml dressing}=42\cdot\text{D mg}$

To find total milligrams of vitamin C in our salad we will add milligrams of vitamin C in each of three ingredients of salad.

$T=(300s+200B+42D)\text{ mg}$

Therefore, our desired expression will be $T=(300s+200B+42D)\text{ mg}$ .

How do you do this algerbra problem 2/3x-8=9

Zigmanuir [339]

Write the division as a fraction
2/3x - 8 = 9
Multiply both sides of the equation by 3
2x-24=27
Move the constant to the right and change the sign
2x=27+24
Add the numbers
2x=51
Divide both sides by 2
2x/2=51/2
X= 25.5

Answer:

x = 2.24

Step-by-step explanation:

I will ASSUME that the 15 represents the angle in degrees

We can make a similar triangle by adding the purple lines as shown.

Any triangle inscribed in a circle with one side as a diameter is a right triangle.

We know it is similar triangle because it shares two common angles, the right angle and the 75° angle at the far right. Then

z = 2Rsin15 = 2(16.7)sin15

x = zsin15 = 2(16.7)sin²15 = 2.237375756799...

What function is shown in the graph above?

Verizon [17]

By definition of linear functions and the comparison with the attached figure, the function that represents the graph is y = (7/15) · x + 4, - 6 ≤ x ≤ 9.

<h3>What kind of function represents the graph?</h3>

Graphically speaking, linear functions represent lines and we see that the line seen in the figure presents two bounds, the points (- 6, 0) and (9, 7). Linear functions are characterized by slope and intercept:

y = m · x + b (1)

Slope

m = (7 - 0)/[9 - (- 6)]

m = 7/15

Intercept

b = 4

By definition of linear functions and the comparison with the attached figure, the function that represents the graph is y = (7/15) · x + 4, - 6 ≤ x ≤ 9.
