The line y=-3x - 8 is graphed below. What additional line would create a system of equations with a solution of (-4,4)?
Answer
A y = 2x + 10
By= 3x + 1
C y = 3x - 9
Dy - 3x + 6
Answers
Answer:
Choice D
Step-by-step explanation:
For this one I would find if the point lands on the line.
Choice A:
What we have to do is to plug in -4 for x and 4 for y.
[tex]y=2x+10\\(4)=2(-4)+10\\4=-8+10\\4\ne2[/tex]
The point is not on this line so this cannot be it.
Choice B:
We pug what we know again.
[tex]y=\frac{1}{3}x+1\\(4)=\frac{1}{3}(-4)+1\\(4)=-\frac{4}{3}+1\\4\ne-\frac{1}{3}[/tex]
The point is not on this line so it can't be it.
Choice C:
We pug in what we know again.
[tex]y=3x-9\\(4)=3(-4)-9\\(4)=-12-9\\4\ne-21[/tex]
The point is not on this line so it can't be it.
The next one has to be it, but we'll check it just in case.
Choice D:
We plug in what we know again.
[tex]y= \frac{1}{2}x+6\\(4)=\frac{1}{2}(-4)+6\\(4)=-2+6\\4=4[/tex]
The point is on this line so this is the line.

Step-by-step explanation:
You have $90 in your bank account. each week you plan to deposit $6 from your allowance and $10 from your paycheck. The equation b=90+(10+6)w gives you the amount b in your account after w weeks from now will you have $195 in your bank account
Answers
Answer: After 6.5625 (or 6 1/2) weeks
Step-by-step explanation: You have to replace b with the 195.
195 = 90 + (10+6)w
Subtract 90 from both sides to get
105=(10+6)w
Simplify
105=16w
Divide both sides by 16 to get 6.5625, or 6.5

2y + 9y + 14x - 7x
11y + 7x
Answer:
11y+7x

Answers
Answer:
55%
Step-by-step explanation:
Percentage of regular coffees = [tex]\frac{33}{60}[/tex] × 100%
= 55%
Answer:
55%
Step-by-step explanation:
To find the percentage of regular coffees, divide 33 by 60, and multiply that by 100:
(33/60) x 100
0.55 x 100
= 55
So, 55% were regular

Mental Math Determine whether each statement is always, sometimes, or never true.An absolute value function of the form f(x) = c|x| is symmetric about the y-axis.
Answers
The statement that "an absolute value function of the form f(x) = c|x| is symmetric about the y-axis" is always true.
How to determine whether each statement is always, sometimes, or never true?The function is given as
f(x) = c|x|
The parent absolute value function is represented f(x) = |x|
Also, the parent absolute value function is symmetric about the y-axis.
This is also true for all functions that take the form f(x) = c|x| where c does not equal 0
Hence, the statement that "an absolute value function of the form f(x) = c|x| is symmetric about the y-axis" is always true

Jose is a botanist studying production of coconuts by two different groups of his
coconut palms. He noticed that Group 1 of trees produced 25 percent more coconuts
than Group 2 did. Based on Jose's observation, if Group 1 produced 165 coconuts,
how many coconuts did Group 2 produce?
Answers
Answer: 132
Step-by-step explanation:
Since we are informed that Group 1 of trees produced 25 percent more coconuts than Group 2 did and that Group 1 produced 165 coconuts, the number of coconuts that Group 2 produce will be:
= [100 / (100 + 25)] × 165
= 100/125 × 165
= 0.8 × 165
= 132
Group 2 produced 132 coconuts.

The hare challenged the tortoise to a rematch race. This time, the hare ran the same speed of 15 meters per second the whole race. The hare didn't even take nap this time. To be nice, the hare gave the tortoise a head start. The tortoise started 200 meters ahead. The tortoise ran 7 meters per second. Create a system of equations to model this situation.
Answers
Answer:
[tex]\left \{ {{h=15s} \atop {t=7s+200}} \right.[/tex]
Step-by-step explanation:
Let [tex]h[/tex] be equal to the number of meters the hare travels.
Let [tex]t[/tex] be equal to the number of meters the tortoise travels.
Let [tex]s[/tex] be equal to the number of seconds that pass.
The hare travels at a speed of 15 meters per second, which means [tex]15s[/tex] represents the number of meters the hare travels depending on the number of seconds that pass.
[tex]h=15s[/tex]
The tortoise travels at a speed of 7 meters per second, which means [tex]7s[/tex] represents the number of meters the tortoise travels depending on the number of seconds that pass.
[tex]t=7s[/tex]
However, because the tortoise got a 200-meter head start, we need to add 200 meters to our equation.
[tex]t=7s+200[/tex]
Here is our system of equations:
[tex]\left \{ {{h=15s} \atop {t=7s+200}} \right.[/tex]

If the measure of angle DBC = (12x - 3), the measure of angle DBE = (5x + 12), and the measure of angle EBC = (3x + 13), find the measure of angle EBC.
Answers
Consider the below figure attached with the question.
Given:
m∠DBC = (12x - 3), m∠DBE = (5x + 12), m∠EBC = (3x + 13).
To find:
The measure of ∠EBC.
Solution:
From the figure, it is clear that,
[tex]m\angle DBC-m\angle DBE=m\angle EBC[/tex]
Putting the given values, we get
[tex](12x-3)-(5x+12)=(3x+13)[/tex]
[tex]12x-3-5x-12=3x+13[/tex]
[tex]7x-15=3x+13[/tex]
[tex]7x-3x=15+13[/tex]
[tex]4x=28[/tex]
Divide both sides by 4.
[tex]x=7[/tex]
Now,
[tex]m\angle EBC=(3x+13)^\circ[/tex]
[tex]m\angle EBC=(3(7)+13)^\circ[/tex]
[tex]m\angle EBC=(21+13)^\circ[/tex]
[tex]m\angle EBC=34^\circ[/tex]
Therefore, the measure of angle EBC is 34 degrees.
