Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation. (-7,-6); y=-5x+2
Answer:
The equation in the slope-intercept form is
y = -5x - 41
Step-by-step explanation:
The given equation in the question is;
y = -5x + 2
The equation of a straight line graph can be written in the form;
y = mx + c
where m is the slope and c is the intercept
From here, we can see that the slope m is -5
Since the line is parallel to the new line we are trying to write its equation, it means that they have the same value of intercept.
Hence, the slope of the new line is also -5
Now, we can write the equation of the new line as;
y = -5x + c
we need to get the value of c here however
To get the value of c, we need to input the value of x and y
From the graph, x = -7 and y = -6
Substituting these values, we have;
-6 = -5(-7) + c
-6 = 35 + c
c = -6 -35
c = -41
So the equation of the new line will be;
y = -5x - 41
find the domain and range of the function represented by the graph
Answer:
Domain = {0,-1,-2,-3}
Range = {0,0,0,0}
Step-by-step explanation:
the domain is the set of inputs (x-values)
the range is the set of output (y-values)
The range is all 0 because the coordinates are (0,0) (-1,0) (-2,0) (-3,0)

Calculate and find the slope of the line
Answer:
1
Step-by-step expansion:
ok so this slope is going up at a whole rate of 1
the slope of this graph is 1
Answer:
The slope is just 1. y=x
Step-by-step explanation:
No matter how you look at it, it goes up one over one. Or you could do it the hard way and take two points and do the slope equation but you'll still get one.
Four lab rats stage a daring escape in broad daylight, eventually establishing a colony behind the laboratory's parking garage. After one month, the population of the colony has risen to eight rats. After two months, the population is sixteen; after three months, thirty-two, and so on. If the pattern continues, how many months will it take for the colony population to reach 1,024 rats?
Answer: 9 months
Step-by-step explanation:
It's a pattern of multiplying by 2.
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
64 x 2 = 128
128 x 2 = 256
256 x 2 = 512
512 x 2 = 1,024

Ava turtle is half as old as her parrot in 10 years her turtle will be 3/4 as old as her parrot .write the equation to represent this situation.How old is avas turtle
Answer:
13
Step-by-step explanation:
I think the turtle would be 13 and 1/3 because we know that the turtle is half as old as the parrot. So if we divide 10 by 3/4 we can get how old the turtle is now
The system of the equation is :
[tex]2x=y\\3y-4x=10[/tex]
Thus, the age of the ava's turtle is 5 years.
Given:
Ava's turtle is half as old as her parrot.
The turtle will be 3/4 as old as her parrot in 10 years.
Let us assume the age of the turtle is x years and the age of the parrot is y years.
According to the first statement, the variables can be related as:
[tex]{x}=\dfrac{y}{2}\\2x=y[/tex]
According to the second statement, the variables can be related as:
[tex]\begin{aligned}x+10&=\dfrac{3}{4}(y+10)\\4(x+10)&=3(y+10)\\4x+40&=3y+30\\4x-3y&=-10\\3y-4x&=10\end{aligned}[/tex]
Thus, the system of the equation is :
[tex]2x=y\\3y-4x=10[/tex]
By solving the above system of the equation, we get x=5 and y=10.
Thus, the age of the ava's turtle is 5 years.

Part A: Determine mVHT.
Part B: Determine mZQTS.
Part C: Determine m ZZHQ.
Answer:
Part A:
m∠VHT = 152°
Part B:
m∠QTS = 152°
Part C:
m∠ZHQ = 28°.
Step-by-step explanation:
Part A:
The given parameters are;
m∠HXU = 113°
Segment BQ and segment UD intersect at m∠XAT = 95°
We have that m∠HXU + m∠HXS = 180° (Angles on a straight line)
Therefore;
m∠HXU = 180° - m∠HXS = 180° - 113° = 67°
m∠HXU = 67°
m∠XAT + m∠XAH = 180° (Angles on a straight line)
m∠XAH = 180° - m∠XAT = 180° - 95° = 85°
m∠XAH = 85°
In triangle XAH, we have;
m∠XAH + m∠HXU + m∠XHA = 180° (Angle sum property of a triangle)
∴ m∠XHA = 180° - (m∠XAH + m∠HXU) = 180° - (85° + 67°) = 28°
m∠XHA = 28°
m∠VHT + m∠XHA = 180° (Angles on a straight line)
m∠VHT = 180° - m∠XHA = 180° - 28° = 152°
m∠VHT = 152°
Part B:
m∠QTS ≅ m∠VHT (Corresponding angles are congruent)
∴ m∠QTS = 152° (Substitution property)
Part C:
m∠ZHQ ≅ m∠XHA (Reflexive property)
∴ m∠ZHQ = 28°.

Note. There is no option of statements to choose.Solving the equation
1/7 + 3/7(3x - 5) = -4Multiplying both sides by 7 to clear fractions
7*1/7 + 7*3/7(3x - 5) = - 7*41 + 3(3x - 5) = -289x - 15 = - 299x = 15 - 299x = - 14x = - 14/9Answer:
x = -14/9
Step-by-step explanation:
1/7 + 3/7(3x - 5) = -4
~Subtract 1/7 to both sides
3/7(3x - 5) = -29/7
~Multiply 7 to both sides
3(3x - 5) = -29
~Simplify left side
9x - 15 = -29
~Add 15 to both sides
9x = -14
~Divide 9 to both sides
x = -14/9

Answer:
28 years

youngest brother's age = x
middle brother's age = x+2
oldest brother's age = x+4
3(x-2) = (x+2)+48
[simplify]
3x-6 = x+50

Dexter read 11 science fiction books and 5 history books. Lena read 9 science fiction books and 4 history books. Compare the students' ratios of science fiction books to history books. 1. Determine the ratios' form: science fiction books to history books 2. Write the ratios as fractions: Dexter: 11 5 ; Lena: 9 4 3. Rewrite with a common denominator. 4. Compare. 5. Answer the question. Determine which shows the correct comparison of the ratios for this problem.
Answer:
1. [tex]Dexter = 11:5[/tex] [tex]Lena = 9:4[/tex]
2. [tex]Dexter = \frac{11}{5}[/tex] [tex]Lena = \frac{9}{4}[/tex]
3. [tex]Dexter = \frac{44}{20}[/tex] [tex]Lena = \frac{45}{20}[/tex]
4. [tex]\frac{45}{20} > \frac{44}{20}[/tex]
Step-by-step explanation:
Given
Dexter
[tex]Science\ Fiction = 11[/tex]
[tex]History = 5[/tex]
Lena
[tex]Science\ Fiction = 9[/tex]
[tex]History = 4[/tex]
Solving (1): Write as ratio
Represent Science Fiction with S and History with H
For Dexter;
[tex]Ratio = S : H[/tex]
[tex]Dexter = 11:5[/tex]
[tex]Lena = 9:4[/tex]
Solving (2): Write ratio as fraction
[tex]Fraction = \frac{S}{H}[/tex]
[tex]Dexter = \frac{11}{5}[/tex]
[tex]Lena = \frac{9}{4}[/tex]
Solving (3): Write as a common denominator
[tex]Dexter = \frac{11}{5}[/tex]
Multiply by [tex]\frac{4}{4}[/tex]
[tex]Dexter = \frac{11}{5} * \frac{4}{4}[/tex]
[tex]Dexter = \frac{44}{20}[/tex]
[tex]Lena = \frac{9}{4}[/tex]
Multiply by [tex]\frac{5}{5}[/tex]
[tex]Lena = \frac{9}{4} * \frac{5}{5}[/tex]
[tex]Lena = \frac{45}{20}[/tex]
Solving (4): Compare both fractions
By comparison;
[tex]\frac{45}{20}[/tex] is greater than [tex]\frac{44}{20}[/tex]
So, we have:
[tex]\frac{45}{20} > \frac{44}{20}[/tex]
