Answer: x = -3
Step-by-step explanation:
2y + x = -15
y = 2x
2y = 2(2x) = 4x
4x + x = -15
5x = -15
x = -3

Carolina is mowing the lawn for a summer job. For each cutting job, she charges an initial fee of $ 8 plus $ 6 for each hour of work. 1-Write an equation (in the form y = mx + b) to represent this problem. 2-If Carolina is paid a total of $ 32, how many hours did she work?
Answer:
F(t) = 8 + 6(t)
Step-by-step explanation:
6*4 = 24
32-24 = 8
so her initial fee is $8
so function is:
F(t) = 8 + 6(t)
Answer:
1. y = 6x + 8
2. 4 hours.
Step-by-step explanation:
x is each hour of work.
y is the total that Carolina is paid.
y = mx + b
32 = 6(x) + 8
Subtract 8 from both sides.
6x = 32 - 8
6x = 24
Divide both sides by 6.
x = 4
Carolina is works 4 hours to be paid 32.
6.8 x + 9.3 6.8 x + 9.3 equals -9.4 + 3.4 (2 minus 5x)
Answer:
x=-0.5
Step-by-step explanation:
6.8x + 9.3= -9.4 + 3.4 (2-5x)
6.8x + 9.3 = -9.4 + 6.8 - 17x
6.8x + 9.3 = -2.6 - 17x
22.8x = -11.9
x = -0.5
solve for the x value of the x intercept of the line 5x-y=-5

Multiply and simplify. y^3 . y^5 . y^-2 .y
A. y^-4
B. 1/y^4
C. y^-5
D. 1/ y^3
Answer:
y^7
Step-by-step explanation:
y^3 . y^5 . y^-2 . y
= y^3 . y^5 . y^-2 . y^1
= y^( 3 + 5 - 2 + 1 )
= y^( 3 + 5 + 1 - 2 )
= y^( 9 - 2 )
= y^7

Answer:
V = 1020.5 yd³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h( r is the radius and h the height )
Here r = 5 and h = 13 , then
V = π × 5² × 13
= 3.14 × 25 × 13
= 1020.5 yd³
You have a box with 5 blue marbles, 4 red marbles, and 9 yellow marbles. You are going to pull out one marble, record its color, put it back in the box and draw another marble. What is the probability of pulling out a blue marble followed by a yellow marble?
Answer:
I think it's 45/196.
Step-by-step explanation:
Not sure though, no explanation.
The probability of pulling out a blue marble followed by a yellow marble 25% or 0.25 .
What is probability ?
Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.
Based on the given conditions, formulate 9 ×9÷((9 + 5 + 4) ×(9 +5 +4))
Calculate the product or quotient = [tex]\frac{81}{(9 +5 + 4) * (9 + 5 + 4)}[/tex]
Calculate the sum or difference= [tex]\frac{81}{(14 + 4) * (9 +5+4)}[/tex]
Calculate the sum or difference = [tex]\frac{81}{18 * (9+5+4)}[/tex]
= [tex]\frac{81}{18 * (14 + 4)}[/tex]
=[tex]\frac{81}{18 * 18}[/tex]
Calculate the product or quotient = [tex]\frac{81}{324}[/tex]
Cross out the common factor = [tex]\frac{1}{4}[/tex]
get the result 25% or 0.25
Therefore, The probability of pulling out a blue marble followed by a yellow marble 25% or 0.25 .

A clock is divided into two equal parts.
(1) 1 - 6
(2) 7 - 12
When the hour hand is on (1), then the time is "after"
When the hour hand is on (2), then the time is "before"
From the attached clock, we have:
(1) The hour hand on 9
(2) The minute hand 1 unit above 9 i.e. 46 minutes
(1) implies that, the time is before 9 i.e. past 8
(2) implies that the minutes is (60 - 46) before 9 or 46 minutes after 8
In (1) and (2) above, we have two interpretations.
1: (60 - 46) minutes before 9
This gives:
14 minutes before 9
2: 46 minutes past 8
i.e. 8 : 46

Find the equation of the circle with a center at (2,-1) and a radius of square root of 12
Answer:
[tex]x^{2}[/tex]+ [tex]y^{2}[/tex] -4x+2y-7=0
Step-by-step explanation:
Given that, center at (2,-1)
let a = 2, b = -1
radius, r = [tex]\sqrt{12}[/tex]
As we know the equation circle is, [tex](x-a) ^{2}[/tex]+[tex](y-b) ^{2}[/tex] = [tex]r^{2}[/tex] when radius and center point is given.
By this formula , we can get,
[tex](x-2) ^{2}[/tex]+[tex](y-(-1)) ^{2}[/tex] = [tex]\sqrt{12} ^{2}[/tex]
[tex]x^{2}[/tex] -4x +4 + [tex]y^{2}[/tex] + 2y + 1 = 12
[tex]x^{2}[/tex]+ [tex]y^{2}[/tex] -4x+2y-7=0
This is the answer.

8x−2=−11+7x +2
Please help me!!
Answer:
x=-7
Step-by-step explanation:
8x - 2 = -11 + 7x + 2
First, separate the terms: move x to one side
subtract 7x from both sides
8x -7x - 2 = -11 + 7x -7x + 2
x - 2 = -11 + 2
Now get x by itself by adding 2 to both sides
x - 2 +2 = -11 + 2 +2
x = -11 + 4
simplify
x = -7
you're welcome

4 cards are taken out of a standard deck (52 cards). What is the probability that the 4th card is a red face card, or a jack given that the jack of diamonds is the first card selected, the queen of hearts is the second card selected, and the third card is the 3 of diamonds?
Answer:
3/49
Step-by-step explanation:
We need to subratact 1 from numerator (as the queen is a red faced card) and 3 from the demonitor as all of them are red cards
Two angles which are on opposite sides of the transversal and between the parallel lines and do not share the same vertex. They are congruent.
Answer:
Interior angles are congruent.
Step-by-step explanation:
We see that angles 3,4,5,6 are between the two parallel lines . These angles are called interior angles.
Angles 3,6 are opposite and do not share the same vertex.
Similarly angles 4 and 5 do not share the same vertex.
They are congruent.
If we look closely we see that angles 3 &4 and angles 5&6 are supplementary angles.
i.e they together make up the 180 degrees on the straight line.
On the outer sides of the parallel lines angles 1&2 and angles 7 & 8 are exterior angles
which also make supplementary angles on the parallel lines.
From the diagram we see that
∠ 5= ∠7
and
∠6 = ∠ 8
as the corresponding angles are equal
∠8=∠3
∠7=∠4
As they are opposite angles
Similarly
∠1=∠6
∠2=∠5 ( opposite angles)
From above
∠5=∠7
but ∠7= ∠4
therefore
∠ 5= ∠4-----------------A
Also
∠6 = ∠ 8
but ∠8=∠3
therefore
∠6=∠8----------------------B
From An and B we conclude interior angles are congruent

Jade has tax deducted from her income at the rate of 24%.
Last month, after tax had been deducted, $1786 of her income remained.
Calculate her income last month before the tax was deducted.
Answer:
$2350
Step-by-step explanation:
Let Jade's total income be X
Therefore,the tax deducted was 24%x
Forming an equation:
X= 24%x + 1786
X = 0.24x + 1786
Collecting like terms
x - 0.24x = 1786
0.76x =1786
x= 1786 ÷0.76
X= $2350
