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.

Answer:

Step-by-step explanation:

Solving the equation

Multiplying both sides by 7 to clear fractions

Answer:

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:

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.

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]

Answer:

Answer:

The answer is C

.......

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)

Hope this helps

Answer:

The answer would be A. It is the population PER YEAR, so it would not be C or D because the population change is only negative, and -2,500,000 people/year is way too much. It must be A, -83,333 people/year. Hope I helped!

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

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

Have a good day! <3

Answer:

28 years

Step-by-step explanation:

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

[add 6 to each side]

3x = x+56

[subtract x from each side]

2x = 56

[divide each side by 2]

x = 28

Answer:

Step-by-step explanation:

(x + 1)/2 = 6

x + 1 = 12

x = 11

(y -10)/2 = -6

y - 10 = -12

y = -2

(11, -2)

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°.
