The first question where you have to write an equation it would be y=2/3x-5
these are the ones that you have to solve for y:
1. y=-3x
2.y=3
3. y=3/2x+5
I recommend you use desmos to graph them, it's pretty useful

Worth 15 points please help
How do you solve this? Please helppp what’s the answer???
Answer:
I won't be able to give you a numerical answer but that's not what your question's asking anyway. Just put a dot at the coordinates (0,-3) and one at (-2,3) and connect them. That's your first line. For the second question put a dot at the intersections (0,1) and one at (-4,-3) and connect them. You should be able to find a point where the two lines intersect. That's the point you need. If you still can't find it, then continue the lines or message me at riztofu on insta. I'll solve your question then.

Her time biking was 5 hours longer than her swimming time. She ran for 4 hours 50 minutes. How long did it take her to complete all three parts of the race? Use the model to help you organize your thinking.
Answer: 12 hrs 40 mins
Step-by-step explanation:
The swimming time was 1 hour 25 minutes.
Her biking time was 5 hours longer than the swimming time so it was:
= 1 hr 25 mins + 5 hours
= 6 hours 25 mins
Her running time was 4 hrs 50 mins.
Add them all up to find the amount of time ran. First add up the minutes:
= 25 + 25 +50
= 1 hr 40 minutes
Hours = 1 + 6 + 4
= 11 hours
Total:
= 11 + 1 hr 40
= 12 hrs 40 mins

Find the measure of the angle indicated in bold
Answer:
x=5
Step-by-step explanation:
hey there
the angles given are corresponding angles meaning that they are congruent
so we set up an equation
23x-5=21x+5
step 1 subtract each side by 5
5-5 cancels out
-5-5=-10
now we have
23x-10=21x
step 2 subtract each side by 23x
21x-23x=-2x
now we have
-2x=-10
step 3 divide each side by 2
-10/-2=5
so we can conclude that
x=5

Directions: Identify the rise, run, and slope of the line below.
Answer:
rise= -2 run= -4 slope= -1/2
Step-by-step explanation:
slope= rise/run
since rise=-2 and run=-4, slope=-2/4, but we have to simplify, so slope=-1/2
In the equation f(x)=5(x+3)2-10 what does the 5 do?
Answer:
you have to distribute the five to all the numbers within the parathetisis
Step-by-step explanation:
so it would be f(x)= 5x+15 and then the rest
Answer:
Do the distributed property with the numbers in the paranthesis so it would b

Step-by-step explanation:
it sounds about right to me. I'm not the best with math
Answer:
C
Step-by-step explanation:
∠ 5 and ∠ 8 are adjacent angles and are supplementary, sum to 180° , then
∠ 8 + ∠ 5 = 180°
∠ 8 + 45° = 180° ( subtract 45° from both sides )
∠ 8 = 135° → C
A culture of bacteria has an initial population of 980 bacteria and doubles every 9 hours. Using the formula P_t = P_0\cdot 2^{\frac{t}{d}}P t =P 0 ⋅2 d t , where P_tP t is the population after t hours, P_0P 0 is the initial population, t is the time in hours and d is the doubling time, what is the population of bacteria in the culture after 13 hours, to the nearest whole number?

If m<4 = 112 degrees, write the measure of EVERY angle in the diagram.
Answer:
m1 = 112 vertical angle
m2 = 180- 112= 68
m3 = 68 vertical with m2
m5 = 112 corresponding with m1
m6 = 68 corresponding with m2
m7 = 68 vertical with m6
m8 = 112 vertical with m5

(1.7 x 103) + (3.5 x 103) = 0
Answer:
5200
Step-by-step explanation:
First solve 10^3 which will give you 1000 then multiply it by 1.7 to get 1700. Then multiple the answer for 10^3, which is 1000, by 3.5 to get 3500. The add the two answers together to get the answer. Which is 1700+3500=5200.

- 3 < n < 6
use trig to determine the value of x for the right triangle. Round answer to nearest tenth. Show work and explain
Answer:
15.4
Step-by-step explanation
From the diagram, we are given;
Adjacent = 12
Hypotenuse=x
Angle of elevation =39°
Using the SOH CAH TOA identity
Cos 39 = 12/x
x = 12/cos39
x = 13/0.7771
x = 15.44
Hence the value of x to nearest tenth is 15.4
The dimensions of a trapezoid are shown below. Which equation could you use to find the Area of the Trapezoid?
Answer:
See Explanation
Step-by-step explanation:
No trapezoid is attached; so, I will solve on a general note
The area of a trapezoid is:
[tex]Area = \frac{1}{2}(Sum\ of\ parallel\ sides) * Height[/tex]
Using the attached image as a point of reference;
The parallel sides are: AD (6cm) and BD (12cm)
The height is 4cm
So, the area is:
[tex]Area = \frac{1}{2} * (6cm + 12cm) * 4cm[/tex]
[tex]Area = 18cm * 2cm[/tex]
[tex]Area = 36cm^2[/tex]
What is the total surface area of the rectangular prism?
Answer:
Total surface = 102.4 cm^2 (second answer in the list of options)
Step-by-step explanation:
Notice that we need to add the surface of 4 rectangles, two have smaller sizes than the other two. A pair of rectangles are 7.2 cm x 4 cm = 28.8 cm^2, while the other pair has 7.2 cm x 2 cm = 14.4 cm^2
There are also two equal bases each one of size 4 cm x 2 cm = 8 cm^2
Now we add two of each of the individual surfaces discussed above to complete the total surface area:
2 * 28.8 + 2 * 14.4 + 2 * 8 = 102.4 cm^2
which agrees with the second answer option provided.
