PLEASE NO LINKS I REALLY NEED THIS ANSWERED On a math test, Larissa was asked to find the points where the following equations intersect.

y = x2+ x – 4
y = -2x + 6

Which line did Larisa make a mistake, please explain
Her work is show below

Answer:

In y=mx+b form, m is the slope. In this case, m=5, therefore the slope is 5.

Answer:

x= 5

pythagorean theorem 3^2+4^2=5^2

And it is a 3-4-5 triangle

Answer:

square root 6

Step-by-step explanation:

Answer:

9 yards

Step-by-step explanation:

The Pythagorean theorem: [tex]a^2+b^2=c^2[/tex]

Where a and b are legs, and c is the hypotenuse.

The hypotenuse is the side opposite from the right angle in the right triangle.

The hypotenuse would be AC, measured 15 yards, because it is opposite from the right angle. BC, the unmeasured side would be a leg. I can call that the "b" leg and AB, the 12 yard side the "a" leg.

Substitute the measures into the theorem to get: [tex]12^2+?^2=15^2[/tex]

[tex]144+?^2=225 ; ?^2=81; ?=\sqrt{81} =9[/tex]

Answer:

19 just add them toghether 7+5+4+3=19 (m)

Answer:

7/10 or 70% or 0.7

Step-by-step explanation:

4 black, 10 red

10+4=14

now you put it over the total marbles

14/20=7/10

i don't know how your teacher wants you to give the answer but it is 7/10 or 0.7 or 70%

Answer:

6 is the answer

Step-by-step explanation:

Answer:

75

Step-by-step explanation:

Answer:

75,000,000

Step-by-step explanation:

first what we do is we do 10^5 which could also be seen as

10*10*10*10*10=100,000

now we times that by 3

100,000*3=300,000

and now divide by 4

300,000÷4=75,000

now times 75,000 by 10^3 (10*10*10=1,000)

75,000*1,000=

75,000,000

75,000,000 is your answer

Answer:

The lateral surface area of the rectangular prism is 204 square feet

Step-by-step explanation:

The remaining part of the question is attached

Solution

Lateral surface area of a rectangular prism is

Height of the prism * perimeter of the base of the prism.

Substituting the given values, we get-

Lateral surface area of a rectangular prism  =

[tex]0.5 *12 * 2(12+5)\\0.5*12*2*17\\0.5*408 \\204[/tex]

The lateral surface area of the rectangular prism is 204 square feet

Step-by-step explanation:

the correct answer is the third one

They make it all so complicated with all of the complex lines doing their own thing, though this is somewhat straight forward once you see it.

With the Domain, these are the x values that the line covers.

For this, it would be -5 ≤ x ≤ 4, because all of the x values are between these two values.

With the Range, these are the y values that the line covers.

For this, it would be -4 ≤ x ≤ 5, because all of the y values are between these two values.

With the X-Intercepts, these are the x values the line crosses for when the y value is 0.

For this, it would be -3 and -1.

With the max, it is the highest point within a graph, for where the y value is the greatest.

For this, it would be x = 4 at the coordinate (4, 5).

SSS po (side-side-side)

Answer:

50

Step-by-step explanation:

In a right angled triangle :

Ratio of the leg Adjacent an angle to the hypotenus can be obtained using the Cosine trigonometric ratio

For an angle of 23° and and adjacent leg of 46

Cos 23 = adjacent / hypotenus

Adjacent / hypotenus = 0.92

46 / hypotenus = 0.92

Hypotenus = 46 / 0.92

Hypotenus = 50

Answer:

31/36

Step-by-step explanation:

1/9 + 3/4 = convert the denominators with finding a common multiple of 9 first = 9 x 4 = 36

9 x 4 = 36  and 4 x 9 = 36

?/36

Then convert the numerators with the numbers you bolded

1 x 4 = 4

and 3 x 9 = 27

= 4/36 + 27/36 = 31/36

Answer:

C

Step-by-step explanation:

Answer: 7 miles per hour

Step-by-step explanation:

This is a fraction equal to 28 miles divided by 4 hours.

We want a unit rate where 1 is in the denominator, so we divide top and bottom by 4.

28 miles ÷ 4

____________

4 hours ÷ 4

= 7 miles

__________

1 hour

=

7 miles

_________

hour

= 7 miles per hour

Answer:

7 miles in 1 single hour

Step-by-step explanation:

28 / 4 = 7

21 / 3 = 7

14 / 2 = 7

7 / 1 = 7

Answer:

-1 and 6 are x intercepts, -4 is y-intercept, -8 is vertex and -2 is axis of symmetry

Answer:

anddddd i just realized i answered the question wrong, the guy above me is correct. good luck.

Answer:

The area if the triangle is 15 yd^2

Step-by-step explanation:

The formula to find the area if a triangle is base × height ÷ 2. So for this question it is 10×3÷2=15

180 - 64= 116

116 divided by 4 = 29

x=29

Have a good day:>

Answer:

x = 29

Step-by-step explanation:

Supplementary angles add up to 180 degrees:

4x+64 = 180

Subtract 64 from both sides:

4x+64-64 = 180-64

4x = 116

Divide both sides by 4:

4x/4 = 116/4

x = 29

Given:

Jerome ate 1/2 of the sandwich , Kevin ate 1/3 of the sandwich, and Seth ate the rest.

To find:

The ratio of jerome's share to kevin's share to seth's share.

Solution:

Jerome ate 1/2 of the sandwich. So,

Jerome's share = [tex]\dfrac{1}{2}[/tex]

Kevin ate 1/3 of the sandwich. So,

Kevin's share = [tex]\dfrac{1}{3}[/tex]

Seth ate the rest. So,

Seth's share = [tex]1-\dfrac{1}{2}-\dfrac{1}{3}[/tex]

                     = [tex]\dfrac{6-3-2}{6}[/tex]

                    = [tex]\dfrac{1}{6}[/tex]

The ratio of jerome's share to kevin's share to seth's share is:

[tex]\dfrac{1}{2}:\dfrac{1}{3}:\dfrac{1}{6}[/tex]

To simplify the ratio multiply the ratio by 6.

[tex]\dfrac{1}{2}\times 6:\dfrac{1}{3}\times 6:\dfrac{1}{6}\times 6[/tex]

[tex]3:2:1[/tex]

Therefore, the ratio of jerome's share to kevin's share to seth's share is 3:2:1.

The right answer is 13mm

Answer:

d

Step-by-step explanation:

Answer:

volume = 24,501.42

Step-by-step explanation: the way i did it:

first find the radius, 34 divided by 2 = 17π

then multiply the radius by itself 17 x 17 = 289

after, multiply 289 by 27 to get 7,803

then multiply 7803 by 3.14 to get 24,501.42

Hope this is correct!

(p.s.) if you do it on a calculator and use the pi symbol (π) the answer would be 24,513.84

Answer:

The slope is 1

Step-by-step explanation:

Take any two points from the graph and plug it into the equation y1-y/x1-x. I took the point (0,3) and (1,4). Plug these two points in to get 4-3/1-0. Simplify to get 1/1 which is equal to 1. Therefore, the slope is 1.

If this answer helps please mark as brainliest

Answer:

The slope is 1

Step-by-step explanation:

There are multiple ways to find the slope on a graph. You can either take two points from the line and do it the normal way (y1-y2/x1-x2), or you can look at the graph and see how much it "rises and runs" from one point to the next point. Since this is a pretty simple graph that is the method I used. Count how many units the line goes up and to the right from one point to the next, and remember the phrase "rise over run" for organizing the fraction. In this one, it rises one and runs one, so 1/1, and that's 1. I hope I could help.
