Answer:
f(10) = -130
Step-by-step explanation:
f(x) = -x² - 3x
f(10) = -(10)² - 3(10)
f(10) = -100 - 30
f(10) = -130
Write the equation for the line whose slope is -1/4 and goes through the point (-2,6)
Answer:
[tex]y = -\frac{1}{4} + \frac{11}{2}[/tex]
Step-by-step explanation:
use y = mx + b where:
y = y-coordinate = 6
m = slope = -1/4
x = x-coordinate = -2
b = y-intercept = what we're solving for to complete the equation
plug the values into the equation
[tex]6 = -\frac{1}{4}(-2) + b[/tex] multiply [tex]-\frac{1}{4}[/tex] and 2
[tex]6 = \frac{1}{2} + b[/tex] subtract [tex]\frac{1}{2}[/tex] from both sides
[tex]b = \frac{11}{2}[/tex]
now we plug m and b into the equation and leave x and y as variables to get the final equation:
[tex]y = -\frac{1}{4} + \frac{11}{2}[/tex]
13x - (10x + 11) + 6 = 13

A company is paying a local radio station to run its commercials. The cost for running commercials is a one-time campaign fee and also a per-second fee for the air time of each commercial. The cost can be modeled by the equation y = 250 + 100x, where x is seconds.
What is the slope, and what does it represent? (1 point)
Group of answer choices
250; it represents the one-time campaign fee
100; it represents the per-second fee of air time
100; it represents the one-time campaign fee
250; it represents the per-second fee of air time
Answer:
The answer is B.
Step-by-step explanation:
100; it represents the per-second fee of air time
What would be the solution to the system of equations: y= -x + 4 y= 3x
Answer:
Step-by-step explanation:
The value of y is given in equation 2
Putting value of y = 3x in equation 1
Y = - x + 4
3x = - x + 4
Bringing like terms on one side
3x + x = 4
4x = 4
x = 4/4 = 1
Now putting value of x = 1 in equation 2
Y = 3x
Y = 3(1) = 3
1/3x + y = 6
-x - 2y = -9

Step-by-step explanation:
Anna&katie together have $60.Anna has $9 more than twice Katie's amount how much money does each have? Write a system and use substitution to solve
Answer:
Ana had $17 and Katie had $43.
Step-by-step explanation:
Since Ana and Katie together have $60, you can express this as follows:
x+y=60, where:
x is the amount that Ana has
y is the amount that Katie has
Also, Anna has $9 more than twice Katie's amount, which can be expressed as:
x=2y+9
The system is:
x+y=60 (1)
x=2y+9 (2)
Now, you can replace (2) in (1) and solve for y:
2y+9+y=60
3y=60-9
3y=51
y=51/3
y=17
Finally, you can replace the value of y in (2) to find x:
x=2(17)+9
y=34+9
y=43
According to this, the answer is that Ana had $17 and Katie had $43.
thanks if you can help or just try it's appreciated.
Answer:
a l parallel n alt angle
b j parallel k corresponding angle
a: b = 1:7
a:c= 4:1
How many times bigger is b than c?
Answer:
a / b = 1/7
b = a x 7
a / c = 4 /1
a = c x 4
b = a x 7
= c x 4 x 7
= c x 28
b is 28 times bigger than c
b is 28 times bigger than c. The conclusion is obtained by rearranging the equations.
What exactly are ratio and proportion?A ratio is an ordered pair of integers a and b, expressed as a/b, where b cannot be zero. A proportion is an equation that sets two ratios equal to each other.
The given ratio;
a: b = 1:7
a:c= 4:1
Rearrange the given ratio we obtained;
b = a × 7
a = c × 4
Put the value of a in b get;
b= c × 4 × 7
Hence, b is 28 times bigger than c.

Parallelogram A B C D is shown. The length of A B is (9 x minus 14) inches and the length of D C is (3 x + 4) inches. In parallelogram ABCD, what is DC? 3 in. 9 in. 13 in. 19 in.
Given:
In a parallelogram ABCD, AB=(9x-14) inches and DC=(3x+4) inches.
To find:
The measure of DC.
Solution:
We know that opposite sides of a parallelogram are equal.
In the parallelogram ABCD, AB and DC are opposite sides. So,
[tex]AB=DC[/tex]
[tex]9x-14=3x+4[/tex]
[tex]9x-3x=14+4[/tex]
[tex]6x=18[/tex]
Divide both sides by 6.
[tex]x=\dfrac{18}{6}[/tex]
[tex]x=3[/tex]
Now,
[tex]DC=3x+4[/tex] inches
[tex]DC=3(3)+4[/tex] inches
[tex]DC=9+4[/tex] inches
[tex]DC=13[/tex] inches
The measure of DC is 13 in.
Therefore, the correct option is C.

BREATHING IN THE DARK, LYING ON ITS SIDE
Answer:
The ruins of the day
Painted with a scar
And the more I straighten out
The less it wants to try
The feelings start to rot
One wink at a time
Oh oh
Forgiving who you are
For what you stand to gain
Just know that if you hide
It doesn't go away
When you get out of bed
Don't end up stranded
Horrified with each stone
On the stage
My little dark age
Picking through the cards
Knowing what's nearby
The carvings on the face
Say they find it hard
And the engine's failed again
All limits of disguise
The humor's not the same
Coming from denial
Oh oh
I grieve in stereo
The stereo sounds strange
I know that if you hide
It doesn't go away
If you get out of bed
And find me standing all alone
Open-eyed
Burn the page
My little dark age
I grieve in stereo
The stereo sounds strange
You know that if it hides
It doesn't go away
If I get out of bed
You'll see me standing all alone
Horrified
On the stage
My little dark age
Giddy with delight
Seeing what's to come
The image of the dead
Dead ends in my mind
Policemen swear to God
Love's seeping from the guns
I know my friends and I
Would probably turn and run
If you get out of bed
Come find us heading for the bridge
Bring a stone
All the rage
My little dark age
I grieve in stereo
The stereo sounds strange
I know that if you hide
It doesn't go away
If you get out of bed
And find me standing all alone
Open-eyed
Burn the page
My little dark age
All alone
Open-eyed
Burn the page
My little dark age

Answer:
The age of man is 42 years and the age of his son is 10 years.
Answer: Father 42 and son 10
Let the age of the father is x years and that of the son is y years.
Then by the given question,
x-2=5(y-2)
or, x-5y=-10+2
or, x-5y=-8
or, x=5y-8
x+2=3(y+2)+8
or, x-3y=6+8-2
or, 5y-8-3y=12
or, 2y=12+8
or, y=20/2
or, y=10
then x=5y-8=50-8=42
Then, the age of father is 42 yrs. and the age of sun is 10 yrs.
