Multiply 2 digit numbers with area models. 26x74

9514 1404 393

Answer:

  3

Step-by-step explanation:

The square root function (√) only gives positive values, so graphs 1 and 4 make no sense.

When x = -3, the y-value is 0, consistent with graph 3.

Step-by-step explanation:

3b - 3.76 = 1.34

3b = 3.76+ 1.34

3b = 5.1

b= 5.1/3

= 1.7

Answer: A

Step-by-step explanation:

Replace x by 3, and y by 2

Answer:

Step-by-step explanation:

x = 3 , y = 2

• Y= x - 1

• 2 = 3-1

• 2 = 2

Answer: 7 miles per hour

Step-by-step explanation:

3 1/2 miles = 7/2 miles

1/2 hours= 30 minutes

So,

In 30 mins, travelled 7/2 miles

In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles

In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.

Hence, the speed is 7 miles per hour.

Answer:

The slope is undefined.

Step-by-step explanation:

If the x value stay the same between a set of points, the slope of the line will be undefined.

Answer:

10 and 12

Step-by-step explanation:

10 and 12

if I divide 3 and 6 by 3 I get 1/2

if I divide 5 and 10 by 5 I get 1/2

1/2 is the first one listed

I cannot reduce 10/12 and get 1/2, I get 5/6

Answer:

-2 is the only answer

Step-by-step explanation:

You know the answer can't be a positive number because a positive multiplied by a positive is a positive number. It is not 0 because 0 X anything is 0. -16 x 16 is way to high. But, -2 x 2 = -4

There are no real solutions

Option F is correct.

An imaginary number is a number that, when squared, has a negative result. Essentially, an imaginary number is the square root of a negative number and does not have a tangible value.

Given equation

[tex]x^{2} =-4[/tex]

Apply square root on both sides of the equation

[tex]\sqrt{x^{2} } =\sqrt{-4}[/tex]

[tex]x=2i[/tex]

2i is imaginary number.

There are no real solutions

Hence, Option F is correct.

Answer:

a₂₁ = 41

Step-by-step explanation:

The nth term of an AP is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 1 and d = a₂ - a₁ = 3 - 1 = 2 , then

a₂₁ = 1 + (20 × 2) = 1 + 40 = 41

Step-by-step explanation:

in essence, these 2 points are the Hypotenuse of a right-angled triangle. the legs are the coordinate differences between the 2 points creating the 3rd point of that triangle at (-10, 7) : the x coordinate of one point, and the y coordinate of the other.

now, we are looking for the midpoint. this midpoint cuts the original line/hypotenuse in half creating a scaling factor of 1/2.

when we create now a similar triangle based on that "half- Hypotenuse", we need to use the same scaling factor also on the legs (the coordinate differences).

so, when we cut the coordinate differences also in half, we get the coordinates for the midpoint on the main line.

xm, ym are the coordinates of the midpoint.

xm = (x1 + x2)/2 = (-10-3)/2 = -13/2 = -6.5

ym = (y1 + y2)/2 = (-6+7)/2 = 1/2 = 0.5

so, the midpoint is (-6.5, 0.5)

Answer:

Step-by-step explanation:

Find the zeroes of the function f ( x ) = x 2 + 12 x + 32

First, because it's a polynomial, factor it f ( x ) = ( x + 8 ) ( x + 4 )

Then, set it equal to zero 0 = ( x + 8 ) ( x + 4 )

Set each factor equal to zero and the answer is x = − 8 and x = − 4 .

Answer:

D) [0, ~)

Step-by-step explanation:

Domain of a Function:

the domain of a function is the set of values of x, the independent variable, that are responsible for the graph of the function.

For Example:

suppose, we have a function:

f(x) = 3x - 1

and it's domain is {1, 2, 3}

that means, the corresponding value of f(x) to these 3 values of x will be DEFINED, I.e., they exist and can be plotted on a graph.

The given function:

Therefore, for the given function, it's domain will be those values of x(the ones plotted on the horizontal line), that give some value to the function ,i.e., for which we can draw it's graph.

and since the graph starts from x = 0 and continues towards infiinity

(the arrow on the curve shows that the graph continues and hasn't yet come to a stop.)

So, that way we got [0, ~). ^^

-24/7=7/7y

y=3.428571

Answer:

y=-4

Step-by-step explanation:

-18=7y+6

-24=7y

y=-24/7(3.428571429)

Answer: 2285.71

Step-by-step explanation:

Rearranging the simple interest formula, we have P = A / (1 + rt), where P is the Principal, r is the annaul rate and t is the time period.

r = R/100 = 5%/100 = 0.05 per year.

Solving the equation:

P = 3200 / ( 1 + (0.05 × 8)) = 2285.7142857143

Answer:

Grandma deposited 8,000

Step-by-step explanation:

I = 3200

r = 5 %

t = 8 years

[tex]P =\dfrac{I*100}{r*t}\\\\P = \dfrac{3200*100}{8*5}\\\\P= 8000[/tex]

Plug in -3 for f(x) into the first equation.

-3 = x^2 - 5x + 3

x^2 - 5x + 6 = 0

Factor!

(x - 3)(x - 2) = 0

Set each binomial equal to 0 to get the x-value of the point.

x = 3

x = 2

Plug each x-value back into the first equation (the answer should be -3, though it's always good to check) to get the y-value.

(3)^2 - 5(3) + 3

9 - 15 + 3

-6 + 3

-3

(2)^2 - 5(2) + 3

4 - 10 + 3

-6 + 3

-3
