Answer:

a) y = 0 +3x

b) 3; the line rises 3 units for each unit to the right

c) (0, 0); the line crosses the y-axis at y=0

Step-by-step explanation:

a. The y-intercept is the point on the y-axis where the line crosses. That point is (0, 0). The y-coordinate there is the value of b in the equation.

The slope is the ratio ...

m = rise/run

The points marked are separated by 3 units vertically for each 1 unit horizontally. Points on the right are above those on the left, so the "rise" is positive for a positive "run".

m = 3/1 = 3

Then the equation is ...

y = 0 + 3x

b. The slope is 3. It is the ratio of rise to run.

c. The y-intercept is 0. It is the y-coordinate of the point where the line crosses the y-axis.

In the figure, AngleRQS Is-congruent-to AngleQLK. 3 lines are shown. Lines S P and K N are parallel. Line R M intersects line S

stepan [7]

Answer:

x=108

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m∠RQS≅m∠QLK -----> by corresponding angles

m∠KLM+m∠QLK=180° -----> by supplementary angles (consecutive interior angles)

we have that

m∠RQS=x° ----> given problem

m∠QLX=x°

m∠KLM=(x-36)° ----> given problem

substitute

$(x-36)\°+x\°=180\°\\2x=180+36\\2x=216\\x=108$

The answer is going to be 2*sqrt(5). You have to split it into perfect squares for it to be simplified... so in this case, I had sqrt(4*5) because sqrt(4) can be simplified... so your answer would be sqrt(4)*sqrt(5) or 2sqrt(5)

The tape diagram shows that there are 155 155155 poems in a collection. A tape diagram with one tape split into 6 equal parts. T

madam [21]

The percentages in this problem are defined as follows:

155 poems: 100% of 155 poems.

31 poems: 20% of 155 poems.

186 poems: 120% of 155 poems.

<h3>How to calculate the percentages?</h3>

A percentage is calculated as the division of the number of desired outcomes by the number of total outcomes, which is then multiplied by 100% to convert the proportion to a percentage.

From the tape diagram given at the end of the answer, the total number of outcomes is given as follows:

155 poems.

Hence the percentage of 155 poems is of:

155/155 x 100% = 100%.

The percentage of 31 poems is of:

31/155 x 100% = 20%.

The percentage of 186 poems is of:

186/155 x 100% = 120%.

<h3>Missing Information</h3>

The tape diagram is given by the image shown at the end of the answer.
