Step-by-step explanation:
y = b + 5x
(10,1)
Solve for b. Brainliest!
Answer:-49
Step-by-step explanation:(10,1)= (x,y) so we can see that x=10 and y=1. Now you put them in the equation 1=b+5*10. Then you get 1=b+50 and you put 50 to the left side and it becomes negative. 1-50=b . Therefore b=-49
Answer:
Step-by-step explanation:
y = 5x + b ⇒ b = y - 5x
(10, 1)
b = 1 - 5(10) = 1 - 50 = - 49
b = - 49

Answer:
5. a^3 + b^3 = (a+b)^3 - 3ab(a+b)
Step-by-step explanation:
(a+b)^3
= (a+b) (a+b) (a+b)
={(a+b) (a+b)} (a+b)
={a(a+b) + b(a+b)} (a+b)
=(a^2 + ab + ab + b^2) (a+b)
=(a^2 + b^2 + 2ab) (a+b)
=a^2(a+b) + b^2(a+b) + 2ab(a+b)
=a^3 + a^2b + ab^2 + b^3 + 2a^2b + 2ab^2
=a^3 + b^3 + 3a^2b + 3ab^2
=a^3 + b^3 + 3ab(a+b)
(a+b)^3 = a^3 + b^3 + 3ab(a+b)
(a+b)^3 - 3ab(a+b) = a^3 + b^3
a^3 + b^3 = (a+b)^3 - 3ab(a+b)
Hope this helped!

The slope of a line is -4, and the y-intercept is -3. What is the equation of the line written in slope-intercept form?
y = -4x - 3
y = 4x - 3
y = -4x + 3
Answer:
y= -4x+-3 = y=-4x-3
The rest are wrong.
Hi there! :)
We are given the slope of the line and its y-intercept.
So, we write the equation in slope-intercept form (y=mx+b)
m is the slope of the line, and b is the y-intercept.
y=mx+b
y=-4x-3
Hence, that's the equation (Option A)
Hope it helps. Use the comment section to clarify your doubts.

In 2003, the average attendance per game for a football team was about (1 × 104) + (9 × 103) + (9 × 102). What is this number in standard form?
show work
Answer:
1.99 * 10^4
Step-by-step explanation:
Here, we want to write the addition in standard form
= (1 * 10^4) + (9 * 10^3) + (9 * 10^2)
= 10,000 + 9000 + 900
= 19,900
so the number in standard form is;
1.99 * 10^4
What are the domain and the range of this function?
If log (100ab^2) is expressed as a function of log b, the result would be:
1). 2 log a + 2 log b
2). 100 log a + 2 log b
3). 2 + log a + 2 log b
4). 2 + 2 log a + 2 log 6
Answer: Choice (3)
2 + log(a) + 2*log(b)
======================================================
Work Shown:
The log rules we'll use are
log(xy) = log(x)+log(y)log(x^y) = y*log(x)log(10) = 1, where the log is base 10So,
c = log(100ab^2)
c = log(100) + log(a) + log(b^2) ......... use log rule 1
c = log(10^2) + log(a) + log(b^2)
c = 2*log(10) + log(a) + 2*log(b) ......... use log rule 2
c = 2*1 + log(a) + 2*log(b) .................... use log rule 3
c = 2 + log(a) + 2*log(b)
Note: The use of rule 3 assumes that all logs shown are in base 10, which is the default assumed base. Rule 3 doesn't work for any general base. The more generalized rule is [tex]\log_b(b) = 1[/tex]. If b = 10, then we get rule 3 above.

0.2x + 1 = 1.6x + 3.1
What value of x satisfies the equation above?
Answer:
x = -1.5
General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
0.2x + 1 = 1.6x + 3.1
Step 2: Solve for x
Subtract 0.2x on both sides: 1 = 1.4x + 3.1Subtract 3.1 on both sides: -2.1 = 1.4xDivide both sides by 1.4: -1.5 = xRewrite: x = -1.5Step 3: Check
Plug in x to verify it's a solution.
Substitution: 0.2(-1.5) + 1 = 1.6(-1.5) + 3.1Multiply: -0.3 + 1 = -2.4 + 3.1Add: 0.7 = 0.7(x,3) and (7,-5) given m= -8/7
Answer:
(0, 3)Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
[tex]m[/tex] - slope
[tex]b[/tex] - y-intercept
Given
[tex]m=-\dfrac{8}{7}[/tex]
and point [tex](7;\ -5)[/tex]
Substitute the value of the slope and the coordinates of the point ot the equation of a line:
[tex]-5=-\dfrac{8}{7\!\!\!\!\diagup}\cdot7\!\!\!\!\diagup+b[/tex] cancel 7
[tex]-5=-8+b[/tex] add 8 to both sides
[tex]-5+8=-8+8+b[/tex]
[tex]3=b\to b=3[/tex]
Therefore we have the equation of the line:
[tex]y=-\dfrac{8}{7}x+3[/tex]
Substitute (x, 3) to the equation:
[tex]3=-\dfrac{8}{7}x+3[/tex] subtract 3 from both sides
[tex]3-3=-\dfrac{8}{7}x+3-3[/tex]
[tex]0=-\dfrac{8}{7}x[/tex] divide both sides by (-8/7)
[tex]0=x\to x=0[/tex]

Anna's college tuition payment is automatically
withdrawn from a separate checking account used only
to pay tuition. At the beginning of the year, the balance
in this account was $13,287.48. After withdrawals each
month for a year, the balance is $1,449.84. How much is
Anna's college tuition payment each month? Estimate to
show that your answer is reasonable.
Answer: $986.47
Step-by-step explanation:
The total tuition fee for the year is;
= 13,287.48 - 1,449.84
= $11,837.64
The payment per month will therefore be;
= 11,837.64/12 months
= $986.47

Quadrilateral ABCD has coordinated A(-4,3)B(-3,6)C(0,8)D(-2,5). Prove that quadrilateral ABCD is a parallelogram.
Answer:
The plotted dots connect to create a parallelogram with two sets of parallel lines in the second quadrant
Step-by-step explanation:
This might be a little tricky to explain but I will try my best.
A parallelogram is a four-sided plane rectilinear figure with opposite sides parallel.
The first pair of numbers is in the second quadrant the second set is also in the second quadrant a little bit up and to the right. The third set in the line a little up, the last set is again in the second quadrant and a little further down and near the middle.
Sorry if the answer isn't what you had hoped for, feel free to ask questions about it and I'll explain the best I can.

What is the equation of the line perpendicular to y=-1/5x -2 and contains the point (2, -10)?
Answer:
y= 5x-20
Step-by-step explanation:
I didn't understand if I had to find the perpendicular line or parallel haha.
You’re welcome :)
Answer:
y = 5x -20
Step-by-step explanation:
for the line to be perpendicular it must have the inverse slope
therefore m = 5
no substitute the point (2, -10) in for (x, y) respectively to find the y intercept
-10 = 5(2) + b
-10 = 10 + b
b = -20
the equation will be y = 5x -20
