Susie could make more so she is correct and we know this because Max would only make $540, but Susie would make $630.

a rental car agency charges 190 per a week plus .25 per mile to rent a car. How many miles can you travel in one week for 370

alekssr [168]

Let m represent the number of miles traveled. If the whole budget amount of 370 is spent, then ...

... 190 + 0.25m = 370

... 0.25m = 280

... m = 280/0.25 = 1120

For 370, you can travel 1120 miles.

Find the angle measure that makes the statement true. Sin 25° = Cos ____ °

givi [52]

Since the sine and cosine functions are cofunctions, they are complementary. The format for this is that sinx=cos(90-x). This works for secant and cosecant and tangent and cotangent. So, sin25°=cos65°.

Write a system of linear inequalities so the points (1, 2) and (4, -3) are solutions of the system, but the point (-2, 8) is not

Verizon [17]

Answer: $\left \{ {{y\leq -\frac{5}{3}x + \frac{11}{3}} \atop {y < 8}} \right$

<u>Step-by-step explanation:</u>

(1, 2) and (4, -3)

First, find the slope (m): $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

m = $\frac{-3-2}{4-1}$

= $-\frac{5}{3}$

Next, choose ONE of the points and input the point and slope into the Point-Slope formula: y - y₁ = m(x - x₁)

y - 2 = $-\frac{5}{3}$ (x - 1)

y - 2 = $-\frac{5}{3}x$ + $\frac{5}{3}$

y = $-\frac{5}{3}x$ + $\frac{11}{3}$

Then, determine which inequality symbol will result in (-2, 8) being False (since it is not a solution):

y ___ $-\frac{5}{3}x$ + $\frac{11}{3}$

8 ___ $-\frac{5}{3}(-2)$ + $\frac{11}{3}$

8 ___ $\frac{1}{3}$

8 > $\frac{1}{3}$

so ≤ makes the statement False

⇒ y ≤ $-\frac{5}{3}x$ + $\frac{11}{3}$

****************************************************************

If you need a "system" of inequalities, then you need another equation.

There are infinite possibilities. Graph the points to see what works.

y < 8 or x > -2 are two examples.

---> I just realized that the system can be simpler than what I did above:

$\left \{ {{x>-2} \atop {y < 8}} \right$

PLEASE HELP ME 15 POINTS<br> what is the value of a<br> what is the value of b

jeyben [28]

Answer:

1st shape: a=60, b=120

Step-by-step explanation:

in the center of the shape, you can draw a circle. 1/6 of a circle is 60. so a is 60. to find b, add the 2 a’s (60+60) and you will get 120. the total amount of a quadrilateral is 360. so 360-120 is 240. u need to divide that by 2 and u will get 120.

i don’t know the second one :(
