Find solutions to the linear equation y=−10x+30.

1 answer:

4 0

Answer: x=-y-30/10

1) subtract 30 from both sides

y−30=−10x

2) divide both sides by -10

-y-30/10=x

3) switch sides

x=-y-30/10

∆JKL~∆MNO and J/K MN =2/3 find the length of NO if KL=12.

Gre4nikov [31]

Answer:

Therefore the length of NO is 18 units.

Step-by-step explanation:

Given:

∆JKL~∆MNO and

$\dfrac{JK}{MN}=\dfrac{2}{3}$

KL = 12.

To Find :

the length of NO = ?

Solution:

Δ JKL ~ Δ LMN ….{Given)

If two triangles are similar then their sides are in proportion.

$\dfrac{JK}{MN} =\dfrac{KL}{NO}=\dfrac{JL}{MO} \textrm{corresponding sides of similar triangles are in proportion}\\$

Substituting the values we get

$\dfrac{2}{3} =\dfrac{12}{NO}\\\\NO=\dfrac{36}{2}=18\\\\NO=18\ unit$

Therefore the length of NO is 18 units.

Question 3 1) What is the slope of the line? YA 1 AX

Kipish [7]

Answer:

Slope: 2

Step-by-step explanation:

Taking any two points on the slope: (0,1) & (1,3)

where (0,1) is (x1,y1) and (1,3) is (x2,y2)

Substituting into the slope formula as below:

$\frac{y2-y1}{x2-x1}$

= (3-1)/(1-0)

= 2/1

= 2

Hence, the slope is 2

Ben's car gets between 18 and 21 miles per gallon of gas. If his car's tank holds 15 gallons, what is the range of distance that

kipiarov [429]

Answer:

Step-by-step explanation:

Ben's car gets between 18 and 21 miles per gallon of gas. If his car's tank holds 15 gallons, it means that the least distance that Ben can drive on one tank of gas would be

18 × 15 = 270 miles.

Also, the most distance that Ben can drive on one tank of gas would be

21 × 15 = 315 miles.

Therefore the the range of distance that Ben can drive on one tank of gas is between 270 miles and 315 miles. If d represents the distance, then the range is

270 ≤ d ≤ 315)
