Answer:
this is a function
Step-by-step explanation:
3x - 2y = 8
2x + 2y = -8
Answer:
(0, - 4 )
Step-by-step explanation:
3x - 2y = 8 → (1)
2x + 2y = - 8 → (2)
Adding (1) and (2) term by term will eliminate the y- term
5x + 0 = 0
5x = 0 , then
x = 0
Substitute x = 0 into either of the 2 equations and solve for y
Substituting into (2)
2(0) + 2y = - 8
0 + 2y = - 8
2y = - 8 ( divide both sides by 2 )
y = - 4
solution is (0, - 4 )
25% of 94?
please explain!
Answer:
23.5Step-by-step explanation:
25% of 94
[tex] = 94 \times \frac{25}{100} [/tex]
[tex] = 94 \times \frac{1}{4} [/tex]
= 23.5 (Ans)
Answer:
25% of 94 is 23.5
Step-by-step explanation:
step 1: Convert the problem to an equation using the percentage formula: P% * X = Y.
step 2: take your percent then turn it into a decimal like 10% is 0.10
step 3: then multiply your decimal by your whole number like 0.10 * 65 to get your answer

[tex] \sf = \frac{3 + 2}{3} + \frac{4 \times 2 + 3}{4} + \frac{6 \times 3 + 5}{6} [/tex]

-3x + b = 6x
solve for x
Answer:
x = 1/9(b)
Step-by-step explanation:
Step 1: Subtract 6x from both sides.
[tex]-3x + b - 6x = 6x - 6x[/tex] [tex]-9x + b = 0[/tex]Step 2: Subtract b from both sides.
[tex]-9x + b - b = 0 - b[/tex] [tex]-9x = -b[/tex]Step 3: Divide both sides by -9.
[tex]\frac{-9x}{-9}= \frac{-b}{-9}[/tex] [tex]x = \frac{1}{9}b[/tex]Therefore, [tex]x = \frac{1}{9}b[/tex].

In the previous activity, you found an equation with a negative unit rate, y = -50x – 100. This equation gave the depth of a submarine, y, given time, x. It assumes that the submarine starts at a depth of 100 feet, and then starts descending at a rate of 50 feet per minute. In this activity, you will graph the equation.
Part A
Graph the equation y = -50x – 100 by going to your math tools and opening the Graph tool. Set the scale of the y-axis to range from -150 to 50, and set the x-values to range from -5 to 10. Paste a screenshot of your graph in the answer field.

What is the equation of the linear model in point-slope form that includes the point (-3, 1) and has a slope of 3?
Please show work for brainliest
Answer:
A) You would use the two points that are closest to the graphed line
(2,7) and (8,13)
B) Slope = change in Y over the change in X:
Slope = (13-7) / (8-2) = 6/6 = 1
Slope = 1
c) Point slope is written as y -y1 = m(x-x1) where m is the slope y1 is the first Y value and x1 is the first x value.
Equation is: y-7 = x-2
d) To rewrite y -7 = x-2 in slope intercept form, you need to isolate y.
To isolate Y add 7 to both sides:
y = x +5
Step-by-step explanation:
The equation of line which passes through point (-7,-2) and having slope 3 is y = 3x + 10.
What is Algebraic expression ?
Algebraic expressions are numbers expressed using letters or alphabets without specifying their values. Algebra taught us how to express unknown values using letters such as x, y, and z. There can also be a single value that is placed before and multiplied by a variable in an algebraic expression in addition to these letters, which are called variables.
Here, it is given that line passes though point (-3,1) and having slope of 3.
Now, Let us find the equation of the line using point-slope equation of line :
(y-y₁) = m(x-x₁)
Substituting all the values in above equation to get the equation of line :
(y-1) = 3(x-(-3))
y -1 = 3x + 9
y = 3x + 9 + 1
y = 3x + 10
Therefore, the equation of line which passes through point (-7,-2) and having slope 3 is y = 3x + 10.

4(y-2)=-0.6(y+0.3 what is the answer and how to do it
Answer:Solution for 0.3(y-2)+0.4y=0.3y-0.6 equation:
0.3(y-2)+0.4y=0.3y-0.6
We move all terms to the left:
0.3(y-2)+0.4y-(0.3y-0.6)=0
We add all the numbers together, and all the variables
0.4y+0.3(y-2)-(0.3y-0.6)=0
We multiply parentheses
0.4y+0.3y-(0.3y-0.6)-0.6=0
We get rid of parentheses
0.4y+0.3y-0.3y+0.6-0.6=0
We add all the numbers together, and all the variables
0.4y=0
y=0/0.4
y=0
