Answer:

I think Rose isn't correct.

Answer:

Rosa is incorrect because if we substitute b, for the number 4. The answer is not equal to 10.

Step-by-step explanation:

(3+9b)-2b=10

(3+9*4)-2*4=10

(3+36)-8=10

39-8=10

31=10

It is incorrect because the numbers are not the same.

Answer:

Step-by-step explanation:

Both sides of the equation are exactly same.

It means regardless the value of x the equation is true.

The equation has infinitely many solutions.

As both sides are equal

There present infinite number of solutions

Answer:

A = (5, 4)

B = (4, 3)

C = (5, 2)

D = (6, 3)

Step-by-step explanation:

Before I do anything, I will write the figure's coordinates for ABCD

A = (2, 3)

B = (1, 2)

C = (2, 1)

D = (3, 2)

Now, a translation means adding and or subtracting the x and y coordinates within the ordered pairs.

3 units right means add 3 units to the value of coordinate x. Coordinate x will always be for any horizontal movement (left and right).

1 unit up means add 1 unit to the value of coordinate y. Coordinate y will always be for any vertical movement (up and down).

Make these adjustments to each ordered pair:

A = (2 + 3, 3 + 1)

A = (5, 4)

B = (1 + 3, 2 + 1)

B = (4, 3)

C = (2 + 3, 1 + 1)

C = (5, 2)

D = (3 + 3, 2 + 1)

D = (6, 3)

Unfortunately I cannot graph the points for you, but if you mark each ordered pair I've given and then connect them together with lines, it will be graphed.

Answer:

The first Option is equivalent to the equation.

Step-by-step explanation:

1) Expand by distributing term.

[tex]15x + 15 - 7x[/tex]

2) Collect like terms.

[tex](15x - 7x) + 15[/tex]

3) Simplify.

[tex]8x + 15[/tex]

Hence, 8x + 15 is equivalent to this equation.

Answer:

Scale factor: 2.5

Step-by-step explanation:

Scale factor is the ratio between corresponding measurements. And a pre image is basically an (original image) while an image is the translated version of the original.

I'm not sure what the best way to explain my answer is, but you can either multiply or divide to find the answer.

4 x 2.5 = 10

8 x 2.5 = 20

10 x 2.5 = 25

5 x 2.5 = 12.5

10/4 = 2.5

20/8 = 2.5

25/10 = 2.5

12.5/5 = 2.5

The football hits the ground at 6.53 seconds

The height function of the football is given as:

[tex]f(t) = -4.9t^2 + 30t + 13[/tex]

When the football hits the ground, f(t) = 0 i.e. the height of the football is 0.

So, we have:

[tex]-4.9t^2 + 30t + 13 = 0[/tex]

Using a calculator, we have:

[tex]t = \{-0.41, 6.53\}[/tex]

The value of time (i.e. t) cannot be negative.

So, we have:

[tex]t = 6.53[/tex]

Hence, the football hits the ground at 6.53 seconds

Step-by-step explanation:

The volume of a trapezoidal prism is 471.5 m³.

An open, flat object with four straight sides and one pair of parallel sides is referred to as a trapezoid or trapezium.

A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases. The legs of a trapezium can also be parallel. The parallel sides may be vertical, horizontal, or angled.

The altitude is the measurement of the angle perpendicular to the parallel sides.

The area of a trapezoid is (1/2)×(sum of the two parallel sides)×height.

We know volume of a trapezoidal prism is [(1/2)×(b₁+b₂)×h}×H.

Therefore, The volume of this trapezoid is,

= (1/2)×(24 + 19)×21 m³.

= (1/2)×(43)×21 m³.

= 471.5 m³.

Step-by-step explanation:

Here, we want to get the number of times the graph of the function intersects the x-axis

Mathematically we need to know the number of roots the function has

We can get this by the use of the discriminant

This is:

D = b^2 - 4ac

b is the coefficient of x which is 0 here

a is the coefficient of x^2 which is 1 here

c is the last number which is 2

So;

D = 0^2 -4(1)(2) = 0-8 = -8

the discriminant value is negative

This means there are no real roots

x-y plane is used for real numbers and thus since there are no real roots, the graph of the equation will not intersect any point on the x-axis

Answer:

w > -1

Step-by-step explanation:

Hello There!

We want to simplify this expression to be more specific we want to isolate the variable (w) using inverse operations

So we want to get rid of the 8 in 8w

8w is the same as 8 times w (multiplication)

The inverse of multiplication is division so to get rid of the 8 we want to divide by 8 but remember whatever we do to one side we want to do to the other side. So we divide each side by 8

-8/8 = - 1

8w/8=w

we're left with w > -1

Total pencils: 17

Total rulers: 15

Step-by-step explanation:

"I will buy 15 pencils."

15 * 8p = £1.20

15 pencils

"Then I will buy as many rulers as possible."

£5 - £1.20 = £3.80

£3.80/30p = 12 remainder 20p

12 rulers

"With my change, I will buy more pencils.”

20p/8p = 2 remainder 4 p

2 pencils
