Marla has $20 to spend on a bed for her dog. The bed she likes is priced at $18.50, and the sales tax is 6%. Does Marla have eno

ugh money for the total cost of the bed? Explain your reasoning.

Yes, because 6% tax of $18.50 is $1.11 and if you add the tax to the amount of the bed the total cost will be $19.61

Find the x-intercept and y-intercept of the line. <br> 3x + 5y = −15

insens350 [35]

Answer:

The x intercept is (-5,0)

The y intercept is (0,-3)

Step-by-step explanation:

To find the x intercept we set y=0 and solve for x

3x+5y = -15

3x+0 = -15

3x = -15

Divide by 3

3x/3 = -15/3

x = -5

The x intercept is (-5,0)

To find the x intercept we set x=0 and solve for y

3x+5y = -15

0+5y = -15

5y = -15

Divide by 5

5y/5 = -15/5

y = -3

The y intercept is (0,-3)

A1 Plumbing Service charges $35 per hour plus a $25 travel charge for a service call. Good Guys Plumbing Repair charges $40 per

AlladinOne [14]

A1 = 35x+25

Good guys = 40x

35x+25 = 40x

subtract 3x x from each side

25 = 5x

divide each side by 5

x = 25/5 = 5

so 5 hours they would be the same cost, anything over 5 hours and A1 would be better

so X>5 for A1 to be the better price

The average value of a function f over the interval [−2,3] is −6 , and the average value of f over the interval [3,5] is 20. Wha

Xelga [282]

Answer:

The average value of $f$ over the interval $[-2,5]$ is $\frac{10}{7}$ .

Step-by-step explanation:

Let suppose that function $f$ is continuous and integrable in the given intervals, by integral definition of average we have that:

$\frac{1}{3-(-2)} \int\limits^{3}_{-2} {f(x)} \, dx = -6$ (1)

$\frac{1}{5-3} \int\limits^{5}_{3} {f(x)} \, dx = 20$ (2)

By Fundamental Theorems of Calculus we expand both expressions:

$\frac{F(3)-F(-2)}{3-(-2)} = -6$

$F(3) - F(-2) = -30$ (1b)

$\frac{F(5)-F(3)}{5-3} = 20$

$F(5) - F(3) = 40$ (2b)

We obtain the average value of $f$ over the interval $[-2, 5]$ by algebraic handling:

$F(5) - F(3) +[F(3)-F(-2)] = 40 + (-30)$

$F(5) - F(-2) = 10$

$\frac{F(5)-F(-2)}{5-(-2)} = \frac{10}{5-(-2)}$

$\bar f = \frac{10}{7}$

The average value of $f$ over the interval $[-2,5]$ is $\frac{10}{7}$ .

Please help ill give brainiest answer

trapecia [35]

Answer:

1: AAS, RQC 2: ASA, SRP

Step-by-step explanation:

(1) We are shown that two angles and one side are congruent in the order of AAS. Make sure you write the letters in terms of the corresponding angles. The angles and sides are congruent because the problem labels it for us. For example, B,A,C=R,Q,S. Answers: AAS, RQC.

(2) We are shown that two angles and one side are congruent in the order of ASA. Make sure you write the letters in terms of the corresponding angles again. For example, P,Q,R=P,S,R. The angles are congruent because the problem labels it for us. Side PR is congruent to side PR by reflexive property. Answers: ASA, SRP.

I hope this helped :) Good luck
