Answer:

k = 3.5

Step-by-step explanation:

0.1 (10k - 15) =2

Distribute

1k - 1.5 = 2

Add 1.5 to each side

k -1.5 +1.5 = 2+1.5

k = 3.5

Answer:

(-2,3)

Step-by-step explanation:

Dont get fooled by the whole equation given to you the main part you should be looking at is (x+2) and (y-3) this gives you the answer for the x coordinate and y coordinate.

x+2 = 0

x = -2

y-3 = 0

y = 3

So now you have both coordinates x and y which is (-2,3)

Quick reasoning: pick the ratio and start adding both values as many times as you reach the value you need: You start with 11:5, add once, you get 22:10; add again, you get 33:15. Add one final time, you get 44:20.

More rigorous: You want to see how many times the length fit in the ratio: that means dividing the length by the first term of the ratio, or 44/11 = 4. At this point you multiply the second term by the number you just found, ie 5x4= 20.

Answer:

x = 62

Step-by-step explanation:

The triangle is isosceles. That means two sides are equal. The angles opposite those equal sides are also equal.

Every triangle has 180 degrees.

The unmarked angle is also x.

x + x + 56 = 180             Combine the left

2x + 56 = 180                 Subtract 56 from both sides

2x = 180 - 56

2x = 124                         Divide by 2

2x/2 = 124/2

x = 62

Explanation:

y = mx + b Calculate the slope, m, from the given point values, solve for b by using one of the point values, and check your solution using the other point values.

A line can be thought of as the ratio of the change between horizontal (x) and vertical (y) positions. Thus, for any two points defined by Cartesian (planar) coordinates such as those given in this problem, you simply set up the two changes (differences) and then make the ratio to obtain the slope, m.

for the slope, m.

A line has the general form of y = mx + b, or vertical position is the product of the slope and horizontal position, x, plus the point where the line crosses (intercepts) the x-axis (the line where z is always zero.) So, once you have calculated the slope you can put any of the two points known into the equation, leaving us with only the intercept 'b' unknown.

for example, answer choice A would be 5^(3+-5) which is 5^-2.

the only choice that does not equal 5^-2 is D because it equals 5^2

Answer:

9 < x < 21

Step-by-step explanation:

Given 2 sides of a triangle then the 3rd side x is in the range

difference of 2 sides < x < sum of 2 sides , that is

15 - 6 < x < 15 + 6 , so

9 < x < 21

[tex]p-5(p+4) = p-(8-p)\\\\\implies p-5p - 20 = p-8+p\\\\\implies -4p-2p = 20 -8 \\\\\implies -6p = 12 \\\\\implies p = -2[/tex]

Answer:

3y = 2x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3y = 2x - 5 ( divide terms by 3 )

y = [tex]\frac{2}{3}[/tex] x - [tex]\frac{5}{3}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{2}{3}[/tex]

Parallel lines have equal slopes , then

y = [tex]\frac{2}{3}[/tex] x + c ← is the partial equation

To find c substitute (6, 5 ) into the partial equation

5 = 4 + c ⇒ c = 5 - 4 = 1

y = [tex]\frac{2}{3}[/tex] x + 1 ( multiply through by 3 to clear the fraction )

3y = 2x + 3 ← equation of parallel line

Answer:

5w + 15

$45

Step-by-step explanation:

(6)*(5) + 15 = $45

The amount of money Nayeli would have saved in W weeks is given by the equation A = 5W + 15

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

After one week of saving, Nayeli will have:

$15 + $5 = $20

After two weeks of saving, Nayeli will have:

$20 + $5 = $25

Continuing this pattern, we can find that after six weeks of saving, Nayeli will have:

$15 + 6($5) = $45

So, after six weeks of saving, Nayeli will have $45.

Amount saved = starting amount + (amount saved per week) × (number of weeks)

Amount saved = $15 + ($5)W   be equation (1)

So, the expression that represents the amount of money Nayeli would have saved in W weeks is

A = $15 + ($5) W

Hence , the equation is A = 5W + 15
