The area of a rectangular
driveway is 2x2 + 15x + 25.
The width of the driveway is
x + 5. What is the length of
the driveway?

Answer:

1,2,4

Step-by-step explanation:

Okay so basically in a triangle, the sum of any two sides should be greater than the third remaining side. So if we had a triangle with sides A, B, and C, A+B>c, A+C>B, and B+C>A. If you look at 1,2, and 4, 1=2=3 which is less than 4. That is why that is not a triangle.

Answer:

[tex]y=-3x-8[/tex]

Step-by-step explanation:

Linear equations are typically organized in slope-intercept form:

[tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis)

1) Plug the slope (m) into the equation

We're given that the slope is -3. Plug -3 into the equation

[tex]y=-3x+b[/tex]

2) Solve for the y-intercept (b)

To solve for b, plug the given point (-1,-5) into the equation as (x,y).

[tex]-5=-3(-1)+b\\-5=3+b[/tex]

Subtract 3 from both sides

[tex]-5-3=3+b-3\\-8=b[/tex]

Therefore, the y-intercept is -8. Plug -8 back into our original equation as b

[tex]y=-3x-8[/tex]

I hope this helps!

Sol➜

We have, tan(A + B) = √3

⇒ tan(A + B) = tan60°

∴ A + B = 60° -----[i]

Again, tan(A - B) = 1/√3

⇒ tan(A - B) = tan30°

∴ A - B = 30° -----[ii]

Now, Adding [i] and [ii], we get

A + B + A - B = 60° + 30°

2A = 90° ⇒ A = 45°

Putting the value of A in [i], we have

45° + B = 60°

∴ B = 60° - 45° = 15°

Hence, A = 45° and B = 15°.

Answer:

[tex] \displaystyle A = {45}^{ \circ} \\ B = {15}^{ \circ}[/tex]

Step-by-step explanation:

we are given two equation and condition

[tex]\displaystyle \begin{cases}\tan(A+B)=\sqrt{3} \\ \tan(A - B) = \dfrac{1}{ \sqrt{3} } \end{cases}( {0}^{ \circ} < A+B < {90}^{ \circ} ) \: \text{and} \: A > B[/tex]

let's work with first equation

recall unit circle so A and B should be in Q:I

[tex] \displaystyle \: A+B = \arctan( \sqrt{3} )[/tex]

[tex] \displaystyle \: A+B = {60}^{ \circ} \cdots \: \text{I}[/tex]

let's work with second equation:

[tex] \displaystyle \: \tan(A - B) = \frac{1}{ \sqrt{3} } [/tex]

[tex] \displaystyle \: A - B = \arctan(\frac{1}{ \sqrt{3} } )[/tex]

[tex] \displaystyle \: A - B = {30}^{ \circ} \cdots \: \text{II}[/tex]

now let's use elimination method to figure out A and B

to do so combine equation I and II

[tex] \displaystyle \underline{\begin{array}{c c c}A+B = {60}^{ \circ} \\ A - B = {30}^{ \circ} \end{array}} \\ 2A = {90}^{ \circ} [/tex]

divide both sides by 2:

[tex] \displaystyle \: \frac{2 A}{2} = \frac{ {90}^{ \circ} }{2} \\ A = {45}^{ \circ} [/tex]

substitute the value of A to the second equation:

[tex] \displaystyle \: {45}^{ \circ} - B = {30}^{ \circ} [/tex]

cancel 60° from both sides:

[tex] \displaystyle \: - B = { - 15}^{ \circ} [/tex]

divide both sides by -1

[tex] \displaystyle \: B = {15 }^{ \circ} [/tex]

hence,

[tex] \displaystyle \: A = {45}^{ \circ} \\ B = {15}^{ \circ} [/tex]

Answer:Look at the 2nd significant digit that the number has.

In a decimal, the first significant digit is the first non-zero digit. The 2nd significant digit is the digit after the first.

if it is less than 5 then round the number down by removing the rest of the number after the 1st significant digit and filling in with zeros;

if it is 5 or more then round the number up by adding one on to the 1st digit and removing the rest of the number and filling in with zeros.

Step-by-step explanation:

8726 rounds up to 9000, because the 2nd significant digit is a 7.

73.283 rounds down to 70 because the 2nd significant digit is a 3.

152 rounds up to 200 because the 2nd significant digit is a 5.

0.003826 rounds up to 0.004 because the 2nd significant digit is an 8.

0.60828 rounds down to 0.6 because the 2nd significant digit is a 0.

Step-by-step explanation:

Answer:

1-2a is the largest for   -1 > a > -2.41

a^2 is the largest for  -2.41 > a.

Step-by-step explanation:

We want to find the expression with the largest value.

Remember that the sign is important here, because:

1 is larger than -10

So we will look at the expressions that, when evaluated in a negative number, give a positive number.

The only two options in the case:

a < -1

are:

1-2a

and

a^2

So we have a linear equation and a quadratic equation.

We know that quadratic equations grow a lot faster than linear equations for all values larger than 1 (or minus one, because the sign does not matter).

if -1 < a < 1, a quadratic function grows really slow, but this is not the case.

So from now, we can guess that a^2 is larger.

But let's solve it graphically.

Let's define two functions:

f(a) = 1 - 2*a

g(a) = a^2

Now we can graph these two, and look at the region a < -1, and see which one is larger.

in the image, you can see that there is a small region from:

-1 > a > -2.41

Where the linear equation is larger, and for:

a < -2.41

The quadratic equation is larger.

Answer:

m∠ECD = 145°

m∠FCA = 35°

m∠PDF = 70°

Step-by-step explanation:

For ∠ECD:

- You can find this angle using supplementary angles. ∠ECD and ∠ECB are supplementary, meaning they add to 180°. Since the measure of ∠ECB is provided, you can subtract that from 180° to get m∠ECD:

  180 - 35 = 145°, so m∠ECD = 145°

For ∠FCA:

- You can solve this problem using the Vertical Angles theorem. It states that vertical angles are congruent. ∠FCA's vertical angle pair is ∠ECB, which is 35°, so you can deduce that m∠FCA = 35°

For ∠PDF:

- You can find the measure of this angle by using supplementary angles like for ∠ECD. ∠PDC is supplementary to ∠PDF, and it's value is given. so you can find PDF by subtracting the value of ∠PDC from 180:

  180 - 110 = 70°; m∠PDF = 70°

Answer:

A=330

Step-by-step explanation:

im not sure which is the length width height

but if length is 10

width is 3/5

height is 15

A=2(wl+hl+hw)=2·(0.6·10+15·10+15·0.6)=330

then the area would be 330

Answer:

f(x) = -4x + 80

Step-by-step explanation:

You are given two points,

(5, 60) and (10, 40)

in order to get the equation, let's use the form slope-intercept form

m = (y1 - y2) / (x1 - x2)

m = (60 - 40) / (5 - 10)

m = 20/-5

m = -4

Get the x intercept

y = mx + b

60 = (-4)(5) + b

b = 60+20

b = 80

so the equation is

y = -4x + 80

f(x) = -4x + 80

Answer:

c

Step-by-step explanation:

f(x)=-4x+80

Answer:

  b, c, d -- (all but the first)

Step-by-step explanation:

The key take-away regarding what relation is or is not a function is the following: a function has no repeated x-values.

The x-values in the table are -3, -1, 0, 2, so any suggested ordered pair with one of those as an x-value cannot be added to the table. The only such pair in the list is the first one (-3, 4). It cannot be added. All of the remaining three pairs can be added and the relation will remain a function.

Answer:

Bryce is wrong in step 1 because he did not distribute 3 over 5/3

Explanation

Given the steps taken by bryce as shown, we are to find where he made an error

[tex]\qquad\begin{aligned} \dfrac83&=3\left(c+\dfrac53\right)\\\\ \\ \dfrac83&=3c+\dfrac53&\green{\text{Step } 1}\\\\ \\ 1&=3c&\blue{\text{Step } 2}\\\\ \\ \dfrac13&=c&\purple{\text{Step } 3}\\\\ \end{aligned}[/tex]

Given the expression;

[tex]\dfrac83&=3\left(c+\dfrac53\right)\\\\ \\[/tex]

Step 1:Expand the bracket using the distributive law;

8/3 = 3c + 3(5/3)

Simplify

8/3 = 3c + 15/3

Step 2: Subtract 15/3 from both sides

8/3 - 15/3 = 3c+15/3-15/3

(8-15)/3 = 3c

-7/3 = 3c

Step 3: Multiply both sides by 1/3

-7/3 * 1/3 = 3c * 1/3

-7/9 = c

Swap

c = -7/9

From the calculation, we can see that Bryce is wrong in step 1 because he did not distribute 3 over 5/3 thereby making his solution incorrect

Answer:

5 is the median

Step-by-step explanation:

Median

Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
