k = 4

Step-by-step explanation:

k is the difference of y-intercepts (where the lines intersect with the y-axis). So, subtract the y-intercept of f(x) from the y-intercept of g(x).

Answer: 29 weeks

Step-by-step explanation:

From the question, we are informed that Caroline bakes cookies in batches of 24 and that she bakes 3 batches of cookies per week. The amount of cookies baked per week will then be:

= 24 × 3

= 72 cookies

The number of weeks that would take her to bake 2,088 cookies will be:

= 2088 / 72

= 29 weeks

Answer:

To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to calculate the discriminant, which is b^2 - 4 a c. When discriminant is greater than zero, the roots are unequal and real. When discriminant is equal to zero, the roots are equal and real.

ANSWER:

when the value of (b^2-4ac) is positive, then the roots are real and distinct.

when it is 0 the roots are equal and if it is negative than its root is not real.

Given:

Total distance covered by Jamie = [tex]6\dfrac{1}{2}[/tex] miles

She ran every day = [tex]\dfrac{1}{6}[/tex] miles

To find:

The number of days in which she go for running.

Solution:

Total distance covered by Jamie [tex]=6\dfrac{1}{2}[/tex] miles

                                                       [tex]=\dfrac{6\times 2+1}{2}[/tex] miles

                                                       [tex]=\dfrac{12+1}{2}[/tex] miles

                                                       [tex]=\dfrac{13}{2}[/tex] miles

She ran every day = [tex]\dfrac{1}{6}[/tex] miles

Now,

[tex]\text{Required number of days}=\dfrac{\text{Total distance covered}}{\text{Distance covered each day}}[/tex]

[tex]\text{Required number of days}=\dfrac{\dfrac{13}{2}}{\dfrac{1}{6}}[/tex]

[tex]\text{Required number of days}=\dfrac{13}{2}\times \dfrac{6}{1}[/tex]

[tex]\text{Required number of days}=39[/tex]

Therefore, the required number of days is 39.

-66d-21 Answer

Answer:

Angle A

Step-by-step explanation:

subtract 3x and 5x

you get 2x

-5-3=

you get -8

divide -8/2x

x=-4

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Sum of the measures is equal to 180° .

So :

[tex]Angle \: \: A + Angle \: \: B + Angle \: \: C = 180 \\ [/tex]

Thus :

[tex](5x - 5) + (3 x + 3) + (5x) = 180 \\ [/tex]

Collect like terms

[tex]13x - 2 = 180[/tex]

Add sides 2

[tex]13x - 2 + 2 = 180 + 2[/tex]

[tex]13x = 182[/tex]

Divide sides by 13

[tex] \frac{13x}{13} = \frac{182}{13} \\ [/tex]

[tex]x = 14[/tex]

_________________________________

[tex]Angle \: \: B = 3x + 3[/tex]

[tex]Angle \: \: B = 3(14) + 3[/tex]

[tex]Angle \: \: B = 42 + 3[/tex]

[tex] Angle \: \: B = 45°[/tex]

Answer: 2.5 meters long

Step-by-step explanation:

Given:

In triangle ABC, [tex]\angle A=90^\circ, AB=1\text{ units}, AC=8\text{ units}[/tex].

To find:

The length of BC.

Solution:

Pythagoras Theorem : In a right angled triangle,

[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]

In triangle ABC, angle A is right angle, so BC is hypotenuse.

Using Pythagoras theorem, we get

[tex]BC^2=AC^2+AB^2[/tex]

[tex]BC^2=(8)^2+(1)^2[/tex]

[tex]BC^2=64+1[/tex]

[tex]BC^2=65[/tex]

Taking square root on both sides.

[tex]BC=\pm\sqrt{65}[/tex]

But side cannot be negative, so [tex]BC=\sqrt{65}[/tex].

Therefore, the length of BC is [tex]\sqrt{65}\text{ units}.[/tex]

Using the Pythagorean Theorem, the length of BC is: 8.1 units.

Recall:

Pythagorean Theorem holds true when solving a right triangle that has side c as hypotenuse and side a and b as the other legs, thus: c² = a² + b².

Triangle ABC is shown in the diagram below, where:

Applying the Pythagorean Theorem, the length of BC is solved as follows:

BC = √(1² + 8²)

BC = 8.1 units

Step-by-step explanation:

2 2/5 = 12/5

-2 2/5= -12/5

To change a mixed number to an improper fraction, take the bottom number or denominator and times by the whole number and then add the top or numerator. So 5*2=10+2=12 put that on top of the denominator you already have or 5

Answer:

y=22.1

Notice how 24.7 and 11.7 are 1.3 times larger than the corresponding sides in the smaller triangle. Therefore, 17 times 1.3 should give us our y value.

17 x 1.3=22.1

22.1=y

Step-by-step explanation:

Answer: y= -3x + 2

Step-by-step explanation:

y=mx+b

m= y2-y1 / x2-x1 = -1 - 5 / 1 - (-1)= -6/2 = -3

y=-3x+b

pick a point and solve for b by plugging in the x and y values of that point.

y=-3x+2

Answer:

The first one

Step-by-step explanation:

1. 36/-3 = -12

2.-4-(-16) =12

3.(-3)(-4) = 12

The first one is the only one which doesn't equal 12. It equals -12 and that's why it doesn't belong.

Answer:

Width of rectangular piece = x = 8 inches

Step-by-step explanation:

Perimeter of rectangular piece = 62 inches

Let width of rectangular piece= x

and length of rectangular piece = x+15

We need to find width i.e value of x

The formula used for perimeter of rectangle is: [tex]Perimeter=2(Length+Width)\\[/tex]

Putting values in formula and finding Width:

[tex]Perimeter=2(Length+Width)\\\\62=2(x+x+15)\\62=2(2x+15)\\62=4x+30\\62-30=4x\\4x=32\\x=\frac{32}{4}\\x=8[/tex]

After solving we get value of x = 8

So, Width of rectangular piece = x = 8 inches

Missing Options:

A. Erica's graph is incorrect, because the slope  should be greater than 9.5.

B. Erica's graph is incorrect, because the y-intercept should be greater than 9.5.

C. Erica's graph is correct, because the slope  should be less than 9.5.

D. Erica's graph is correct, because the y–intercept  should be less than 9.5.

Answer:

A. Erica's graph is incorrect, because the slope  should be greater than 9.5.

Step-by-step explanation:

Given

Clive:

[tex]d = 9.5h[/tex]

Erica:

[tex]m = 9[/tex] --- slope

[tex]b =0[/tex] --- y intercept

First, we need to determine the equation of Erica's earnings using

[tex]d = mh + b[/tex]

Where

m = slope = 9

b = y intercept = 0

So, the equation becomes

[tex]d = 9 * h + 0[/tex]

[tex]d = 9h + 0[/tex]

[tex]d = 9h[/tex]

This implies that Erica earns 9 dollars per hour

For Clive:

[tex]d = 9.5h[/tex]

This means that Clive earns 9.5 dollars per hour

From the question, we understand that Erica earns more than Clive.

So, we can conclude that Erica's graph is incorrect because the slope must be greater than 9.5.

When the slope is greater than 9.5, then she earns  more than Clive.
