m=1 or m=-3

Step-by-step explanation:

when m=1,

(1+1)sq+1=5

4+1=5

5=5

True statement

when m=-3,

(-3+1)sq+1=5

(2)sq+1=5

4+1=5

5=5

True statement

Step-by-step explanation:

Answer:

X = 45

Step-by-step explanation:

a^2 + b^2 = c^2

60^2 + a^2 = 75^2

3,600 + a^2 = 5,625

- 3,600            - 3,600

____________________

    a^2= 2025

square root them

a^2 = a

2025 = 45

so x =45

Answer:

-2

Step-by-step explanation:

since the base are the same you add the exponent.

4x+2 + 2x-1= -3x-17

4x+2x +3x =-17-2+1

9x =-18

x=-2

Answer:

5

Step-by-step explanation:

it would be 5. x is 5 so if it is wrong sorry its best e a while since i done that kind of math

Answer:

Step-by-step explanation:

Answer:

1/20

Step-by-step explanation:

Simple probability is found by counting all the results which fit requirements and dividing by all possible results.

To find probability of two results in a row, multiply chance of first result by chance of second result.

Since you are replacing the marble before the second draw, we don’t have to figure out the various changes in odds for the different possible first draws. It’s just that simple.

There are 5 black marbles

There are 4 red marbles

There are always 20 marbles in all

5/20*4/20=1/4*1/5=1/20

By coincidence, the same as the chance of drawing the white marble in one draw.

Answer:

y = 2x + 24

Step-by-step explanation:

Slope-intercept form equation => y = mx + b

m = slope = change in y / change in x

b = y-intercept

✔️using two pairs of values form the table, (-6, 12) and (-5, 14):

Slope (m) = (14 - 12)/(-5 -(-6))

m = 2/1

m = 2

✔️To find b, substitute (x, y) = (-6, 12) and m = 2 into y = mx + b.

12 = 2(-6) + b

12 = -12 + b

12 + 12 = b

24 = b

b = 24

✔️To write the equation, substitute m = 2 and b = 24 into y = mx + b:

y = 2x + 24

Answer:

[tex]x + 4[/tex]

Step-by-step explanation:

The question have missing details.

Because, the question says she collected some cans "after picnic"; This means that she has some cans "before picnic"

So, we assume that she has x bags of can before the picnic.

[tex]After\ Picnic = 4[/tex]

So, the total number of bags collected is:

[tex]Total = Before + After\ Picnic[/tex]

[tex]Total = x + 4[/tex]

If x is 5, then she took 9 bags of can to the recycling center

If x is 2, then she took 6 bags of can to the recycling center

If x is 0, then she took 4 bags of can to the recycling center

Answer:

Step-by-step explanation:

The nth term:  [tex]a_n=a_1+d(n-1)[/tex]

So:

    a₄ = a₁ + 3d

18 =  a₁ + 3d   ⇒   3d =  18 - a₁

    a₇ = a₁ + 6d

39 = a₁ + 6d

39 = a₁ + 2(18 - a₁)

39 = a₁ + 36 - 2a₁

39 = 36 - a₁

a₁ = -3

3d = 18 - (-3)

3d = 21

d = 7

So the nth term:

                            [tex]a_n = -3 + 7(n-1)\\\\a_n=-3 +7n - 7\\\\a_n = 7n - 10[/tex]

Another way

10 is not included so open bracket

Answer:92.4

Step-by-step explanation:

4x+7x=132

10x=132

x=132/10

x=13.2

4x=4×13.2

=52.8

5x=7×13.2

=92.4

Answer:

-2

Step-by-step explanation:

Answer:

4.

Step-by-step explanation:

28 = 2*2*7

48 = 2*2*2*2*3

72= 2*2*2*3*3

So the HCF = 2*2 = 4.

Answer:

hcf stand's for

highest common factor

and must be prime numbers

so the answers 3

Answer:

A=90

B=18

C=111

D=39

E=35

Step-by-step explanation:

Given:

The given function is:

[tex]y=-32x^2+90x+3[/tex]

To find:

The range of the given function.

Solution:

We have,

[tex]y=-32x^2+90x+3[/tex]

It is a quadratic function because the highest power of the variable x is 2.

Here, the leading coefficient is -32 which is negative. So, the graph of the given function is a downward parabola.

If a quadratic function is [tex]f(x)=ax^2+bx+c[/tex], then the vertex of the quadratic function is:

[tex]Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)[/tex]

In the given function, [tex]a=-32,b=90,c=3[/tex].

[tex]\dfrac{-b}{2a}=\dfrac{-90}{2(-32)}[/tex]

[tex]\dfrac{-b}{2a}=\dfrac{-90}{-64}[/tex]

[tex]\dfrac{-b}{2a}=\dfrac{45}{32}[/tex]

The value of the given function at [tex]x=\dfrac{45}{32}[/tex] is:

[tex]y=-32(\dfrac{45}{32})^2+90(\dfrac{45}{32})+3[/tex]

[tex]y=\dfrac{2121}{32}[/tex]

The vertex of the given downward parabola is [tex]\left(\dfrac{45}{32},\dfrac{2121}{32}\right)[/tex]. It means the maximum value of the function is [tex]y=\dfrac{2121}{32}[/tex]. So,

[tex]Range=\left\{y|y\leq \dfrac{2121}{32}\right\}[/tex]

[tex]Range=\left(-\infty, \dfrac{2121}{32}\right ][/tex]

Therefore, the range of the given function is [tex]\left (-\infty, \dfrac{2121}{32}\right ][/tex].

Answer: 100

Step-by-step explanation:

The formula for the area of a trapezoid is (B1+B2)/2*h

so substitute:

(8+12)/2*10

20/2*10

10*10

100

Answer:

100 sq inches

Step-by-step explanation:

Simply use the formula for finding the area:

[tex]\frac{1}{2} * (sum of parallel sides) * height\\= \frac{1}{2} * (8 + 12) * 10\\= \frac{1}{2} * 20 * 10\\= 100 sq. inches[/tex]

Answer:

True

Step-by-step explanation:

[tex]11^2=121\\12^2=144\\121<131<144[/tex]
