I DONT UNDERSTAND PLZZZ HELP

Answer:

Step-by-step explanation:

Function

We can see all 3 graphs have y-intercept of -2

Since the slope is negative, it is decreasing function, therefore possible options are A or C

Checking x-intercept and comparing with same of A and C

As we see it matches Option C, which is the answer

Answer:

d = 4

Step-by-step explanation:

Answer:

d = 4

Step-by-step explanation:

–24 + 12d = 2(d – 3) + 22

–24 + 12d = 2d - 6 + 22

–24 + 12d = 2d + 16

–24 + 12d - 2d = 16

12d - 2d = 16 + 24

10d = 16 + 24

10d = 40

d = 4

Answer:

r minus 38 equals to 134 this might be m not certain

The correct equation is, [tex]r-38=134[/tex] and Rajesh have 172 crystals .

Let us consider that, Rajesh had r  crystals.

Mariana had 134  crystals in her collection.

Since, Rajesh has 38 more crystal than Marina . So , if we subtract 38 from crystals Rajesh have then both have equal number of crystals.

So,     [tex]r-38=134[/tex]

Now, find crystals present in Rajesh collection.

                   [tex]r-38=134\\\\r=134+38=172[/tex]

Thus, Rajesh have 172 crystals .

Answer:

34 degrees

Step-by-step explanation:

If ABD = 64, and CBD is 30, we can use PWP( Part Whole Postulate)

Step 1.CBD + ABC = ABD

Step 2. Substitute

30 + ABC = 64

Step 3. Isolate ABC

34 = ABC

ABC is 34 degrees

9514 1404 393

Answer:

  34°

Step-by-step explanation:

It should be fairly intuitive that the two smaller angles add to give the value of the larger one. (Even if it's not, the angle sum theorem tells you this is true.)

  ∠ABC + ∠CBD = ∠ABD

  ∠ABC + 30° = 64°

  ∠ABC = 34° . . . . . . . . . subtract 30° from both sides of the equation

Store Z

1 - Find out what the price per can is at each store

Store X

4 cans for $2.38

2.38price/4can(s) = price per can

Store x is $0.598/can

Store Y

5 cans for 3.00

$3.00/5

$0.60/can

Comparing these to store Z; store Z is still the better deal.

Answer:

x = 2

Step-by-step explanation:

(Square both sides)

20 - 8x = x^2

(Solve 20 - 8x = x^2)

x = 2 , x = 10

x = 10 is false, so the answer is x = 2.

Answer:

x=2

Step-by-step explanation:

√20-8x=x

2√5-2x=x (by simplfing redical expression)

4(5-2x)=x^2 (square both side)

20-8x=x^2

20-8x-x^2=0

-x^2-8x+20=0

x^2+8x-20=0

x=2

Note:There is a another answer x=-10 But it's wouldn't fit out with this equation

Answer:

h(n) = - 2n - 13

Step-by-step explanation:

Given

m = - 2n - 13, that is

h(n) = - 2n - 13

Step-by-step explanation:

Factor out the common terms from the given terms:

[tex]x^2-4x=0[/tex]

You can factor out x from both:

[tex]x(x-4)=0[/tex]

Rewrite, setting each equal to 0:

[tex](x)(x-4)=0\\\\x=0\\\\x-4=0[/tex]

Simplify the second equation by solving for x:

[tex]x-4=0\\\\x-4+4=0+4\\\\x=4[/tex]

Therefore, x=0 or x=4

Answer:

all real numbers

Step-by-step explanation:

The graphs of positive and negative x^2 parabolas will always have a domain of all real numbers.  Even though you only have a portion of the graph and see a "restriction" on your domain values, it is incorrect to assume that the domain is limited to what you can see.  As the branches of the parabola keep going up and up and up, the values of x keep getting bigger and bigger and bigger.  Again, this is true for all + or - parabolas.      .......

Answer:

a. h(t) = 5t + 10

b. 70

c. h(5) = 35 means that in 5 seconds, it will be 35 feet above ground.

Step-by-step explanation:

a. Since the elevator is already 10 feet of the ground, u have to add that in the equation. And since it's 5 feet per second, 5 will be a multiplier so:

h(t) = 5t + 10

b. We have the equation already and in the equation it said that "t" represents the seconds so just replace 1 with 12:

h(12) = 5(12) + 10

h(12) = 60 + 10

h(12) = 70

c. Refer to b that we just did if u will, "t" represents seconds so h(t) becoming h(5) means 5 seconds. So h(5) = 35 means that in 5 seconds, it will be 35 feet above ground.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

[tex]-x + 2y = 4[/tex]

a) writing the equation in the slope-intercept form

We know that the slope-intercept form of the equation of the line is

[tex]y=mx+b[/tex]

where m is the slope of the line

so writing the equation in the slope-intercept form

[tex]-x + 2y = 4[/tex]

[tex]2y=4+x[/tex]

[tex]y=\frac{1}{2}x+2[/tex]

b) Identify the slope of the line represented in part a

As the equation in slope-intercept form is

[tex]y=\frac{1}{2}x+2[/tex]

Here,

m = slope = 1/2     ∵ [tex]y=mx+b[/tex]

c) What is the slope of the line perpendicular to the line in steps a and b

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

As the slope = 1/2

So the slope of the perpendicular line will be: -2

d. Write the equation of the perpendicular line in slope-intercept form.

Therefore, the point-slope form of the equation of the perpendicular line that goes through (-2,1) is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = -2 and the point (-2,1)

[tex]\:y-1=-2\left(x-\left(-2\right)\right)[/tex]

[tex]y-1=-2\left(x+2\right)[/tex]

Add 1 to both sides

[tex]y-1+1=-2\left(x+2\right)+1[/tex]

[tex]y=-2x-3[/tex]

Answer:

[-7, 6]

Step-by-step explanation:

The range is the y values that the equation/line covers.

The line's lowest point is -7 and the line's highest point is 6. The value is defined at both -7 and 10 since there is a closed circle in both locations- so we use brackets.
