Answer:
59 is D

because with the point (-3,7) you substitute it into the equation, making it: 7=4x+b. solve for b. then you have y=4x+19. work out the algebra in the possible choices and whatever equals y=4x+19 will be the answer. in this case, its D.

60 is C

same as above, you do the algebra of the equation. bring the one over after doing distribution with the 4 and voila!

61 is A

a relatively easy one, all you do is the the slope -4 where m goes, and 3 where b goes. y= -4x+3

62 is C.

this one requires more work.

chose one of the points, in this case (2,7) and put them into the equation.

but wait, you need a slope!

you get that use the formula (y2-y1)/(x2-x1) which will be

(7-5)/(2-3) which will be

-2.

now you have y-7= -2(x-2)

voila!

63 is C. y= 1/2x+3

64 is B. (3, -5)

66 is B. negative. the line goes \ ( not / which is positive)

67 would be A. because it is positive and the I and the E are in the right places.

70 is C. 2/3. as before, remember we can but the points into this equation and have (6-4)/(3-0) which = 2/3

71 is D. y= 3x+10

72 is C. a third degree monomial

**Answer:**

158.2/106 = 1.49245283 grams per mL

**Step-by-step explanation:**

**Answer:**

**Step-by-step explanation:**

He has owned a dog for 9 years, and this time is one year less than twice as long as he has owned a cat.

So, we can express this like:

Solving for :

Therefore, he has owned a cat for 5 years.

your friend has owned a cat for 17 years, because 9 times 2 subtracted by 1 equals 17

30 cm

15 cm

15 squared cm

**Answer:**

**The correct answer is D. 15 squared centimeters.**

**Step-by-step explanation:**

**1. Let's review the data given to us for solving the question:**

Base one = 10 centimeters

Base two = 5 centimeters

Height = 2 centimeters

**2. Let's find out the area of the trapezoid, using the following formula:**

Area = 1/2 (Base one + Base two) * Height

Replacing with real values:

Area = 1/2 (10 + 5) * 2

Area = 1/2 (15 * 2) = 1/2 (30)

Area = 15 centimeters ²

**The correct answer is D. 15 squared centimeters.**

c) which yard has more room for my kids play in.

d) Which yard requires more fence to enclose?

**Answer:**

a) yard 1: 220yd^2 yard 2: 225yd^2

b) yard 1: 64yd. yard 2: 60yd

c) yard 2

d) yard 1

**Step-by-step explanation:**

area=base×height

perimeter=2×base+2×height

**Answer:**

a) 220 yd for the OLD HOUSE

a) 225 yd for the CURRENT HOUSE

b) 64 for the OLD HOUSE

b) 60 for the CURRENT HOUSE

c) the CURRENT HOUSE has more room for the kids (the area is bigger (area=space inside)

d) the OLD HOUSE requires more fence, because the perimeter is bigger (perimeter=the outside of the square)

Hope this helped!

186 minutes is 3 hours and 6 minutes. As a decimal this is 3.1 hours and as a mixed number it is 186/60.

The 250 **pounds **of food will last for 20.83 days.

An **equation **is a combination of different **variables**, in which two mathematical **expressions **are equal to each other.

Given that,

Initial **quantity **of food = 250 pounds,

Since, mountain **climbers **begin to eat 12 pounds per day,

Let the food will **last **for x days,

The **equation **can be **written **as,

12x = 250

x = 20.833

The **food **will **last **for 20.83 days.

To know more about **Equation **on:

#SPJ5

Use the equation y=mx+b where m is the slope (how much it increases each time) and b is the y intercept (starting point).

Your equation would be: y=12x+0 because they eat 12 pounds each day and they start out having eaten 0 pounds.

To solve the equation, plug in the total amount of food for y and use algebra to solve for x:

250=12x

(divide by 12)

(250/12)=x

X=20.833

Their food would last approximately 20 days. (Make sure you round if required)
