Answer:

x intercept = (-5,0)

y intercept = (0,7)

Step-by-step explanation:

Answer:

One

Step-by-step explanation:

When you count the units from one point to another, the answer is one. The units are one to the right then one up. 1/1

Step-by-step explanation:

slope =1

since the intercepted part of X_ axis and y_ axis are equal

so , the line make 45 angle with x_ axis

slope = tan O =1

Result, Rachel can be certain that the temperature is suitable for her cake.

Rachel cannot be certain that the temperature displayed on the oven is suitable for cooking her cake.

The manufacturer's claim of a 5% error on the displayed temperature means that the actual oven temperature can be off by 5% in either direction. To calculate the range of possible actual temperatures, we need to find 5% of 310°C. 5% of 310 = (5/100) * 310 = 15.5°C This means that the oven temperature could be 15.5°C higher or 15.5°C lower than the displayed temperature.

To find the maximum possible temperature, we add the error to the displayed temperature: 310°C + 15.5°C = 325.5°C Since the maximum possible temperature is slightly above 325°C, Rachel cannot be certain that the temperature is suitable for cooking her cake, as it needs to be cooked at a temperature below 325°C. It's important for Rachel to consider using an alternative thermometer or verifying the actual temperature with the oven manufacturer to ensure the cake is cooked at the desired temperature.

Answer:

x = 8

y = 3

Step-by-step explanation:

11x - 20y = 28

3x + 4y = 36

11x - 20y = 28

11x = 20y + 28

x = [tex]\frac{20}{11}[/tex]y + [tex]\frac{28}{11}[/tex]

3x + 4y = 36

3 ( [tex]\frac{20}{11}[/tex]y + [tex]\frac{28}{11}[/tex] ) + 4y = 36

[tex]\frac{104}{11}[/tex]y = [tex]\frac{312}{11}[/tex]

y = 3

x = [tex]\frac{20}{11}[/tex]y + [tex]\frac{28}{11}[/tex]

x = [tex]\frac{20}{11}[/tex] ( 3 ) + [tex]\frac{28}{11}[/tex]

x = 8

Answer:

$65.50

Step-by-step explanation:

Cost of Abe's ticket = $32.75

Tickets for children age 12 and under was of that price.

This means Abe's brother also paid $32.75 for tickets

Cost of Abe's brother tickets = $32.75

How much did Abe have to pay to get himself and his little brother into the park?

Total cost of the tickets = $32.75 + $32.75

= $65.50

OR

Total cost of the tickets = $32.75 × 2

= $65.50

Two triangles, ABC and DEF, similar. <ABC = 101° and <BCA = 39°. Find the angle of FDE!

40°

The sum of all triangle angle is 180°

101 + 39 = 140°

180 - 140 = 40°

So, the angle of FDE is 40°

Answer:

Step-by-step explanation:

Asymptotes 3

g(x) = [tex]\frac{3x}{x^2-3x-10}[/tex]

Factors of denominator will be,

x² - 3x - 10 = x² - 5x + 2x - 10

                 = x(x - 5) + 2(x - 5)

                 = (x + 2)(x - 5)

Therefore, factored form of g(x) will be,

g(x) = [tex]\frac{3x}{(x + 2)(x - 5)}[/tex]

Asymptotes 4

h(x) = [tex]\frac{(x-5)}{x^{2} + 14x + 40}[/tex]

      = [tex]\frac{x-5}{x^{2}+10x+4x+40}[/tex]

      = [tex]\frac{x-5}{x(x+10)+4(x+10)}[/tex]

      = [tex]\frac{x-5}{(x+10)(x+4)}[/tex]

Given:

[tex]x^2+kx-98=0[/tex]

One of the two roots of the given equation is double  the additive inverse of the other.

To find:

The value of k.

Solution:

Let two roots of the given equation are [tex]\alpha[/tex] and [tex]\beta[/tex].

According to the question,

[tex]\beta=2(-\alpha)[/tex]        (Additive inverse of [tex]\alpha[/tex] is [tex]-\alpha[/tex])

[tex]\beta=-2\alpha[/tex]

If [tex]\alpha[/tex] and [tex]\beta[/tex] are roots of the quadratic equation [tex]ax^2+bx+c=0,[/tex] then

[tex]\alpha+\beta=-\dfrac{b}{a}[/tex]

[tex]\alpha\beta=\dfrac{c}{a}[/tex]

We have,

[tex]x^2+kx-98=0[/tex]

Here, a =1, b=k and c=-98.

[tex]\alpha+\beta=-\dfrac{k}{1}[/tex]

[tex]\alpha-2\alpha=-k[/tex]           [tex][\because \beta=-2\alpha][/tex]

[tex]-\alpha=-k[/tex]

[tex]\alpha=k[/tex]           ...(i)

Now,

[tex]\alpha\beta=\dfrac{c}{a}[/tex]

[tex]\alpha(-2\alpha)=\dfrac{-98}{1}[/tex]          [tex][\because \beta=-2\alpha][/tex]

[tex]-2\alpha^2=-98[/tex]

Divide both sides by -2.

[tex]\alpha^2=49[/tex]

Taking square root on both sides.

[tex]\alpha=\pm \sqrt{49}[/tex]

[tex]\alpha=\pm 7[/tex]

Using (i), we get

[tex]k=\pm 7[/tex]

Therefore, the value of k is either -1 or 1.

Answer:

x=72/11

Step-by-step explanation:

Answer: y - $50 = $5*(x - 3)

Step-by-step explanation:

We know that each ticket is sold at $5.00

The band initially had an amount of money M.

We know that after selling 3 tickets, the band had $50

We can write this as:

M + 3*$5.00 = $50

M + $15 = $50

M = $50 - $15 = $35

We want to write the equation for the account in the point-slope form.

We know that the slope will be equal to the cost of a single ticket, and we already have the point:

x = 3

y = $50

Then we can write:

y - $50 = $5*(x - 3)

This is the equation we wanted to find.

Answer:

y = 2

3y - 9 = - 3 ( add 9 to both sides )

3y = 6 ( divide both sides by 3 )

y = 2
