Answer:

The two lines are neither

Step-by-step explanation:

∵ The equations of the lines are

∵ In the 1st equation a = 8 and b = 1

∴ m1 = [tex]\frac{-8}{1}[/tex] = -8

∴ The slope of the 1st line is -8

∵ In the 2nd equation a = 4 and b = 3

∴ m2 = [tex]\frac{-4}{3}[/tex]

∴ The slope of the 2nd line is [tex]\frac{-4}{3}[/tex]

→ By using the facts above

∵ m1 ≠ m2

∴ The two lines are not parallel

∵ m1 × m2 = -8 × [tex]\frac{-4}{3}[/tex] = [tex]\frac{32}{3}[/tex]

∴ m1 × m2 ≠ -1

∴ The two lines are not perpendicular

∴ The two lines are neither parallel nor perpendicular

Answer:

and? obviously bc 3 isnt a even number so then the answer wont be even

Answer:

A, B, E

Step-by-step explanation:

The slope is the same (1/4x)

it is a translation given the y intercept moved it 5 units

they are both positive

Answer:

A. [tex] \sqrt {38}[/tex]

Step-by-step explanation:

Since the given point lie between 6 and 7 and is close to 6.

Therefore, the given point represents the [tex] \sqrt {38}[/tex].

Slope is the change in y over the change in x:

Slope = (-7 - 1) / (2 - 5)

Slope = -8/-3

Slope = 8/3

Answer:

The amount of time Jill spent to do her homework  

= 9 1/2 hours. which equals to  570 minutes.

Which means, the amount of times Jack needed to do his is  

= 570 minutes x 1.5

= 855 minutes which equals to 14 1/4 hours

hope this helps

Answer:

Step-by-step explanation:

1) Time spent by Jack = Time spent by Jill * 1  1/2

                                [tex]= 9\frac{1}{2}*1\frac{1}{2}\\\\=\frac{19}{2}*\frac{3}{2}\\\\=\frac{19*3}{2*2}\\\\=\frac{57}{4}\\\\=14\frac{1}{4} hours[/tex]

2) Time spent by Jill = Time spent by Jack ÷  1 1 /2

                                 = 18 1/4 ÷ 1 1/2

                                 = 73/ 4 ÷ 3/2

                                 [tex]= \frac{73}{4} * \frac{2}{3}\\\\=\frac{73}{2}*\frac{1}{3}\\\\=\frac{73*1}{2*3}\\\\=\frac{73}{6}\\\\=12\frac{1}{6} hours[/tex]

3) Third number = Sum of three numbers - Sum of two numbers

Sum of two numbers = [tex]8\frac{2}{3}+8\frac{1}{6}\\[/tex]

                                   [tex]= \frac{26}{3} +\frac{49}{6}\\\\=\frac{26*2}{3*2}+\frac{49}{6}\\\\=\frac{52}{6}+\frac{49}{6}\\\\=\frac{52+49}{6}\\\\=\frac{101}{6}\\[/tex]

Third number = 22 8/15 - 101/6

                       [tex]= \frac{338}{15}- \frac{101}{6}\\\\= \frac{338*2}{15*2}- \frac{101*5}{6*5}\\\\= \frac{676}{30}- \frac{505}{30}\\\\= \frac{676-505}{30}\\\\= \frac{171}{30}\\\\=5 \frac{21}{30}\\\\= 5 \frac{7}{10}[/tex]

Answer:

Answer:

[tex]-2^{\circ}\text{F}[/tex]

Step-by-step explanation:

Let [tex]x[/tex] be the temperature on the first day

Second day temperature

[tex]x+7[/tex]

Third day temperature

[tex]x+7-10[/tex]

Fourth day temperature was [tex]1^{\circ}\text{F}[/tex]

[tex]x+7-10+6=1\\\Rightarrow x+3=1\\\Rightarrow x=1-3\\\Rightarrow x=-2^{\circ}\text{F}[/tex]

On the first day the temperature was [tex]-2^{\circ}\text{F}[/tex]

Answer:

30

Step-by-step explanation:

We can ignore the fact they are similar altogether. It's known that all 3 angles of a triangle add up to 180, so:

180=102+48+m

180=150+m

30=m

Answer:

A. 30 degrees

Step-by-step explanation:

They are similar aka the same or congruent and since you know all three angles you just match them up.

Answer:

2/5 mile

Step-by-step explanation:

Let's give the total distance the variable x.

1/4x = 1/10

x = 4/10

x = 2/5

Answer:

Step-by-step explanation:

first, you would want to find the common denominator

3/8 (salads) = 3/8

1/4 (sandwiches) = 2/8

add them together to find out how much students and eating either salads or sandwiches

3/8 + 2/8 = 5/8

this means 5/8 of 24 students are eating either salads or sandwiches

24 students = 24/24 as a fraction

find the common denominator of 5/8 and 24/24

24/24 = 24/24

5/8 = 15/24

the final answer would be that 15 students out of 24 are eating a lunch other than a salad or sandwich

The number of people eating lunches other than salads or sandwiches is 3.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, In a cafeteria, 5/8 of the students are eating salads, and 1/4 are eating sandwiches.

So, The number of people eating salads is (5/8)×24 = 15.

And the number of people eating sandwiches is (1/4)×24 = 6.

Therefore, The number of people eating lunches other than salads or sandwiches is (24 - 15 - 6) = 3.

Answer:

x = 11, lucky you, this stuff is easy

Step-by-step explanation:

110 - 11 = 99

9 x 11 = 99

99 + 11 = 110

Answer:

x = 11

Step-by-step explanation:

9x + 11 = 110

- Pass the 11 to the other side of the equation (grouping similar terms) and then perform the following operation:

9x = 110 - 11

9x = 99

- Now we have to obtain x by dividing 9 on both sides of the equation:

(9/9)x = 99/9

x = 99/9, which is divisible by 11.

Answer:

x = -1/9

Step-by-step explanation:

[tex]\frac{18}{x} = -2[/tex] multiply by 1/18 to cancel out

[tex]x = -2(\frac{1}{18} )\\x = -\frac{2}{18} \\x = -\frac{1}{9}[/tex]

Hey there!

18/x = -2

Multiply both sides by x

-2x = 18

Divide both of your sides by -2

-2x/-2 = 18/-2

Cancel out: -2x/-2 because it gives you 1

Keep: 18/-2 because it helps us solve for our answer

x = 18/-2

18/-2 = 18 divided by -2 ➡️ -9

Thus your answer is: x = -9 ✅

Good luck on your assignment and enjoy your day!

Step-by-step explanation:

1000 ml to 1 L

(786 ml) / (1000 ml) = 0.786 L

0.786 L liquids of liter did the scientist to use for this experiment

Division is the process of splitting a number or an amount into equal parts.

here, we have,

A scientist used 786 milliliters of an liquid for an experiment.

we know,

1000 ml to 1 L

so, we get,

(786 ml) / (1000 ml) = 0.786 L

Hence, 0.786 L liquids of liter did the scientist to use for this experiment.

Answer:

y = 360x+200

Step-by-step explanation:

We will use the concept of finding the equation of a line using two coordinates (x1,y1) and (x2,y2)

If after 3 months, ethan has 560 dollars in his savings, and after 6 months, he has 920 dollars, this can be represented as coordinate points (3,560) and (6,920)

The equation of a line in point slope form is expressed as;

y = mx+c

m is the slope = ∆y/∆x = 920-560/6-3

m = 360/3

m = 120

Get the intercept;

Substitute m = 120 and any of the points to get c, using the point (3,560)

x = 3, y = 560

560 = 120(3)+c

560 = 360+c

c = 560-360

c = 200

Get the required equation by substituting m and c into y = MX+c

y = 360x+200
