Answer:
A) y = -1/2x + 2
Step-by-step explanation:
The line is negative, so you will have a negative slope
The line is crossing the y- axis at 2 so the y- intercept is 2.
Now do rise over run or rise/run
The lines rise is 2 and the run is 4
2/4 = 1/2 and since the line is negative the slope is negative -1/2
y = -1/2x + 2
Hope this helps ya!!

Solving systems of equation using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
3x = y + 2
3x + 2y = 5
Step 2: Rewrite Systems
3x = y + 2
Subtract 2 on both sides: 3x - 2 = yRewrite: y = 3x - 2Step 3: Redefine Systems
y = 3x - 2
3x + 2y = 5
Step 4: Solve for x
Substitution
Substitute in y: 3x + 2(3x - 2) = 5Distribute 2: 3x + 6x - 4 = 5Combine like terms: 9x - 4 = 5Isolate x term: 9x = 9Isolate x: x = 1Step 5: Solve for y
Define equation: 3x + 2y = 5Substitute in x: 3(1) + 2y = 5Multiply: 3 + 2y = 5Isolate y term: 2y = 2Isolate y: y = 1Bob's Gift Shop sold 750 cards for Mother's Day. One salesman, Bella, sold 2% of the cards sold for Mother's Day. How many cards did Bella sell?

The sides of a square field are 28 meters. A sprinkler in the center of the field sprays a circular area with a diameter that corresponds to a side of the field. How much of the field is not reached by the sprinkler? Round your answer to the nearest hundredth. Use 3.14 for π.
Answers
Answer:
168.24784 m²
Step-by-step explanation:
Area of the square:
28 x 28=784 sq. m.
Area of the circle:
π(r²)=π(14)²=196π
=615.75216
Area not covered by the sprinkler:
784-615.75216=168.24784 m²
Answer:
The sprinkler does not reach 168.56 m² of the field.
Step-by-step explanation:
Find the circular area sprayed by the sprinkler.
A = πr² Use the formula.
A = π(14)² Substitute. Use 14 for r.
A ≈ 3.14 × 14² Substitute. Use 3.14 for π.
A ≈ 3.14 × 196 Evaluate the power.
A ≈ 615.44 Multiply.
The area of the circular area is about 615.44 ft².
Find the area of the square field.
A = s² Use the formula.
A = 28² Substitute. Use 28 for s.
A = 784 Evaluate the power.
The area of the square field is 784 m².
Find how much of the field is not reached by the sprinkler. Subtract the circular area sprayed by the sprinkler from the area of the square field.
784 − 615.44 = 168.56
Use the graph below for this question: A 6 4 3 What is the average rate of change from x = -1 to x = -2? (1 point) 2 - 2 4 -1
Answers
Answer:
- 2
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 2, - 1 ] , then
f(b) = (f(- 1) = 5 ← corresponding value of y (- 1, 5 )
f(a) = f(- 2) = 7 ← corresponding value of y (- 2, 7 ) , thus
average rate of change = [tex]\frac{5-7}{-1-(-2)}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2

Step-by-step explanation:
the formula to find the surface is A= 2 π r h + 2 π r 2
where r is the radius and h the height. you subsitute it with your value.
r = 9 yd and h = 11 yd
so, A= 2 π r h + 2 π r 2 = 2 x π x 9 x 11 + 2 x π x 9^2 ≈ 1130.97336 yd

The way to get the answer is...
is over of=percent over 100
so for this situation it would look like this...
[tex]\frac{x}{40}[/tex] = [tex]\frac{45}{100}[/tex]
Cross multiply and you will get...
1800 = 100x
get x by itself, so divide 100 by both sides
So you get
x=18

Which pair of triangles MUST be similar?
A. Triangle 5 has a 25 degree angle and a 75 degree angle. Triangle 6 has a 25 degree angle and a 70 degree angle.
B. Triangles 1 and 2 each have a 40 degree angle.
C. Triangle 7 has a 40 degree angle and a 35 degree angle. Triangle 8 has a 40 degree angle and a 105 degree angle.
D.Triangles 3 and 4 are both scalene. Each have a 65 degree angle.
Answers
Answer:
C
Step-by-step explanation:
The total measurement of a triangle is 180
Triangle 7 has a 40 degree angle and 35 degree angle.
40+35=75
180-75=105
Triangle 8 has the same angle that is 40 degrees and 105. And if you do the same math, you would get 35 for the missing angle of triangle 8

Can someone explain Slope to me? I literally have no idea what is from my teacher or from Aleks. I don't get what y1 and y2 are and i don't get what rise or run is. I have no idea how to get slope (brainliest for whoever explains a function too)
Answers
Yeah, I know Alex sucks. SO slope is the change in Y over x. So to find slope for ex. is lets use points (8,4) and (6,5) the equation to find slope is Y2-Y1 over X2-X1 or Y2-Y1 / X2-X1 and that basically the y's on the points you have. In this case it will be 4 and 5 since y always comes second or after the x. What I like to do is this X1(8), Y1(4) and X2(6), Y2(5). After you have that set up you just put them in the equation it will be 5-4/6-8 which is -1/2 use calculator. So Y is the y-axis and X is the x-axis.
Function is when every input(x) has only one output(y) . For example if we have the table
X,1 , 4 , 5, 9, 10 this is not a function because the -3 has both 9 and 10 for an output.
Y,2, 6 ,6, -3 , -3
A function will look more like this
1 2 3 4 5 6
2 4 6 8 10 12 every output has only one input

determine the x value for the vertex and whether this value is a maximum or a minimum
a. maximum at x = -1.25
b. maximum at x = 1.25
c. minimum at x = -1.25
d. minimum at x = 1.25
Answers
Answer: D
Explanation:
Use the vertex formula, -b/2a. Because the quadratic formula is ax^2+bx+c, -b would be 5 in this case and a would be 2 in this case. Plug the numbers in and you get 5/4. The AOS or vertex would be 5/4 or 1.25. Because the a-value is a positive in this equation, the parabola would have a minimum.
