Answer:
y = -3x - 7
Step-by-step explanation:
turn into slope-intercept form:
9x + 3y = 8: subtract 9x to isolate y
3y = -9x + 8: divide by three to isolate again
y = -3x + 8/3 (line): Substitute y and x and replace 8/3 with b
-4 = -3(-1) + b: distribute
-4 = 3 +b: isolate b by subtracting 3
-7 = b
Substitute for b in original equation
y = -3x - 7
Answer:
y=-3x-7
Step-by-step explanation:
First you need to change the equation to slope intercept form. so the equation becomes y=-3x+8/3. now you change it point slope, y-y1=m(x-x1), y--4=-3(x--1), which also becomes y+4=-3(x+1), now you multiply. -3 times x and 1 which makes the equation, y+4= -3x+-3, then subtract from each side since its a positive number. so now the equation y= -3x-7

Your friend states that he has quarters and dimes in his pocket that total to $5.00. He
also states that there are 6 more quarters than dimes. If there are 26 coins altogether,
how many quarters and dimes are there?
Need help!!
Answer: There are 16 quarters and 10 dimes.
Step-by-step explanation:
Let x = Number of quarters
y= Number of dimes.
As per given,
x+y = 26 (i)
x= y+6 (ii), substitute this in (i), we get
y+6+y= 26
⇒2y+6=26
⇒ 2y = 26-6=20
⇒ 2y =20
⇒ y =10 [Divide both sides by 2]
Put this in (ii), x= 10+6 =16
So there are 16 quarters and 10 dimes such that 16 (0.25)+10(0.10)= $5 .

The fraction 6/20 can also be simplified to 3/10, which is the same as 0.3 in decimal form.
To calculate 6 divided by 20, you simply perform the division operation. Divide the numerator (6) by the denominator (20):
6 ÷ 20 = 0.3
The result of 6 divided by 20 is 0.3. This means that if you divide 6 into 20 equal parts, each part will be 0.3.
In decimal form, the fraction 6/20 is equivalent to 0.3. Decimal notation is useful when dealing with fractions that don't easily simplify into whole numbers. In this case, the division results in a decimal less than 1, representing a fraction that is less than a whole. The fraction 6/20 can also be simplified to 3/10, which is the same as 0.3 in decimal form.

What are the properties used to solve 4(x+3)=20
Answer:
Multiproperty
Step-by-step explanation:
To solve this problem, we use different properties to arrive at our answer.
Given expression;
4(x + 3) = 20;
First we use the distributive property to expand;
4x + 12 = 20
Now use subtraction property by adding (-12) to both sides;
4x + 12 + (-12) = 20 + (-12)
4x = 8
you can now divide by 4,
x = 2

Answer:
There are no solutions.
Step-by-step explanation:
6−4n<−1−4n
Step 1: Simplify both sides of the inequality.
−4n+6<−4n−1
Step 2: Add 4n to both sides.
−4n+6+4n<−4n−1+4n
6<−1
Step 3: Subtract 6 from both sides.
6−6<−1−6

Answer:
2) [tex]\frac{1}{\sqrt[6]m^{5}}[/tex]
Step-by-step explanation:
As per the laws of indices:
[tex]\frac{x^{a} }{x^{b} } = x^{a - b} \\\\and \\ \\(x^{a})^b = x^{ab}[/tex]
Therefore:
2-(1/3) = 5/3
So m ^(5/3)
5/3 multiplied by -1/2 = -5/6
so m^(-5/6)
Another law of indices:
[tex]x^{\frac{a}{y} } = \sqrt[y]{x^{a} }[/tex] and when there is something raised to a negative fraction do the reciprocal.
