Answer:

y=2x+5

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(13-25)/(4-10)

m=-12/-6

m=2

y-y1=m(x-x1)

y-25=2(x-10)

y=2x-20+25

y=2x+5

Answer:

[tex]x=90\\y=-40[/tex]

Step-by-step explanation:

Let's set up a system of equations using the given information.

x+y=50

x-y=130

We can solve this system using elimination. In this case, we can eliminate x by subtracting the two equations.

[tex]x-x+y-(-y)=50-130\\x-x+y+y=50-130[/tex]

[tex]2y=-80[/tex]

Divide both sides by 2.

[tex]y=-40[/tex]

Then, plug -40 in for y to solve for x:

[tex]x+y=50\\x+(-40)=50\\x-40=50\\\text{Add 40 to both sides}\\x=90[/tex]

Therefore..

[tex]x=90\\y=-40[/tex]

Answer:

It will 26 weeks to save for the cruise starting from a balance of $140

(It will take 30 weeks in total, if you start saving from $0)

Step-by-step explanation:

let x = number of weeks

Given starting balance = $140

⇒ 140 + 35x = 1050

⇒ 35x = 1050 - 140

⇒ 35x = 910

⇒ x = 910 ÷ 35

⇒ x = 26

Answer:

l = 81

w = 27

Step-by-step explanation:

l = 3x (x2)

w = x (x2)

l = 6x (has two sides so we x2)

w = 2x

6x + 2x = 8x

8x = 216

x = 27 (divide both sides)

w = 27

l = 27 x 3 = 81 (length is 3x bigger than width)

81 + 81 + 27 + 27 = 216

Answer:

2[7x(y – 2) – 6(3y – 4)]

Step-by-step explanation:

If you go down the answer choices and find the solution, this one matches.  Look at picture for better explaining.

The expression will be equal to 2[7x(y-2) - 6 (3y - 4)].

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The given expression will be solved as:-

=    2  [  7x(  y-2 ) -  6 ( 3y - 4 ) ].

=   14x ( y - 2 ) - 12 ( 3y - 4 ) ]

=   14xy  -  28x -  36y  -  48

Therefore expression will be equal to 2[7x(y-2) - 6 (3y - 4)].

Answer:

-4, 9, -1

Step-by-step explanation:

x³ - 4x² - 41x - 36

= x²(x + 4) - 8x² - 41x - 36

= x²(x + 4) - 8x(x + 4) - 9x - 36

= x²(x + 4) - 8x(x + 4) - 9(x + 4)

= (x + 4)(x² - 8x - 9)

= (x + 4) (x - 9)(x + 1)

so the zeros of f(x) are: -4, 9, -1

Answer:

150

Step-by-step explanation:

∠2 and ∠4 are vertically opposite angles and they are congruent.

The required value of the given sum is given as 4.8. Option B is correct.

Given that,
To estimate the sum of 3.62 + 1.16 by rounding each addend to the nearest tenth.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.

Here,
Given expression,
= 3.62 + 1.16
Round the values to the nearest tenth,
= 3.6 + 1.2
= 4.8

Thus, the required value of the given sum is given as 4.8. Option B is correct.

Answer:

Step-by-step explanation:

We know that angles BAD and DAE are supplementary, so the measure of angle DAE is 180-133=47 degrees.

Because of this, we can determine that angle ADE measures 180-82-47=51 degrees.

Now, since triangles ADE and BCE are similar, we can say that the measure of angle ABC is 47 degrees and the measure of angle BCE is 51 degrees.

Finally, to find the measure of angle ADC, we can notice that its the supplement of angle ADE, meaning ADC measures 180-51=129 degrees.

Answer:

Inconsistent

4x + 2y = 6   and   4y = -8x + 4

Step-by-step explanation:

Inconsistent: parallel lines, no solutions

Consistent dependent: same line, infinite solutions

Consistent independent: intersects at one point, one solution

Therefore, the pair of lines are INCONSISTENT.

Both lines have negative slopes.  As they are parallel, the slopes will be the same for both lines.

Therefore, solution is:

4x + 2y = 6   and   4y = -8x + 4

Because:

4x + 2y = 6  ⇒  y = -2x + 3

4y = -8x + 4  ⇒  y = -2x + 1

Both lines have same slope of -2

Considering that it has an angle of 90º degrees, the triangle is classified as:

B. right

In this problem, two angles are 40º and 50º. Since the sum of the angles is of 180º, we have that:

x + 50 + 40 = 180

x = 90º.

Hence, it is a right triangle, and option B is correct.

Answer:

Ric is 7 years old.

Step-by-step explanation:

Choose variables for everyone's ages. I'll choose [tex]r[/tex] for Ric's age, [tex]p[/tex] for Paul's age, and [tex]t[/tex] for Tom's age.

Since Ric's age is half of Paul's age, we can write this equation:

[tex]r=\frac{1}{2}p[/tex]

Since Tom is two years younger than Paul, we can write this equation:

[tex]t=p-2[/tex]

Since the sum of all their ages is 33 years, we can write this equation:

[tex]r+p+t=33[/tex]

Since we know [tex]t[/tex] and [tex]r[/tex] in terms of [tex]p[/tex], we can replace them in the equation above as follows:

[tex]r+p+t=33\\(\frac{1}{2}p)+p+(p-2)=33[/tex]

Now we can solve for [tex]p[/tex] to find [tex]r[/tex] later:

[tex](\frac{1}{2}p)+p+(p-2)=33\\\frac{5}{2}p-2=33\\\frac{5}{2}p=35\\5p=70\\p=14[/tex]

Now that we know that [tex]p=14[/tex], we can substitute 14 for [tex]p\\[/tex] in the equation[tex]r=\frac{1}{2}p[/tex]:

[tex]r=\frac{1}{2}p\\r=\frac{1}{2}(14)\\r=7[/tex]

Ric is 7 years old.
