The line x - y = 5 passes through points (-5,0) and (0,5)
the line in slope intercept form is y = x + 5 and plug in the point to see if the equation is true.

Can I get some help

butalik [34]

4x + 2x -5(x - 3) = 18

4x + 2x - 5x - 15 = 18

4x + 2x - 5x = 18 + 15

4x + 2x - 5x = 33

4x - 3x = 33

x = 33

I'm not sure my answer is right or wrong

I hope it's helpful!!

C is the center of the circle. Find the area of the segment shown in the figure,

Semmy [17]

Answer: A 28.50 sq. u

Step-by-step explanation:

In the given figure , radius of the circle : r= 10 u

Central angle made by Arc ED: $\theta$ = 90° ( right angle )

Now , the area of the segment is given by :-

Area of segment = Area of sector (ECD) - Area of triangle(ECD) (i)

Formula : Area of right triangle = 0.5 x Base x Height

Area of sector = $\dfrac{\theta}{360^{\circ}}\times\pi r^2$

Using above formulas in (i) and substituting corresponding values , we get

Area of segment =

$\dfrac{90^{\circ}}{360^{\circ}}\times\pi (10)^2-0.5\times10\times10\\\\=\frac{1}{4}(3.14)(100)-50\\\\=78.5-50=28.5\ sq.u$

Hence, the correct answer is A 28.50 sq. u

west deposited $15,000 in a savings account earning 2.5% simple interest what was the total interest earned at the end od 8 year

Lelechka [254]

2.5% of 15,00$ would be 375$. Assuming the "simple interest" is yearly, you would multiply 375 by 8, which is 3000$ :P (Another way to solve this would be to multiply the 2.5 by 8, which would be 20. and 20% of 15,000$ would also be 3,000$)

I don’t get how to solve it plz help!!

Shtirlitz [24]

This function is consist of two subfunction with different domains.

f(-1) means x= -1 ≤ 1 and we will use subfunction -x+2 => f(-1)=-(-1)+2= 1=2=3

f(3) means x=3 > 1 and we will use subfunction x∧2-4x+6 =>

f(3)= 3∧2-4*3+6= 9-12+6=3

Good luck!!!

An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 160 engines

abruzzese [7]

Answer:

Test statistic Z = 2.1097

Step-by-step explanation:

Step(i):-

Given that size of the sample 'n' = 160

Given that mean of the Population(μ) = 5.3pounds/square inch

The Standard deviation of the population(σ) = 0.6

Mean of the sample(x⁻) = 5.4

Level of significance =0.1

Step(ii):-

Test statistic

$Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{5.4-5.3}{\frac{0.6}{\sqrt{160} } }$

Z = 2.1097

Final answer:-

Test statistic Z = 2.1097
