Determine the slope and y -intercept for each line shown. Then write the equation of the line (will give Brainliest)
Answer:
1.
[tex]y=\frac{1}{4}x+2[/tex]
m= [tex]\frac{1}{4}[/tex]
b= 2
2.
[tex]y=-\frac{1}{3}x+1[/tex]
m= [tex]-\frac{1}{3}[/tex]
b= 1
3.
[tex]y=3x+4[/tex]
m= 3
b=4
Step-by-step explanation:
1. The line intersects the y-axis at the point (0,2) therefore its y-intercept is b=2.
The line rises up 1 unit on the y-axis for every 4 units on the x-axis therefore the line has a slope of m=1/4.
Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that [tex]y=\frac{1}{4}x+2[/tex]
2. The line intersects the y-axis at the point (0,1) therefore its y-intercept is b=1.
The line down up 1 unit on the y-axis for every 3 units on the x-axis therefore the line has a slope of m= -1/3.
Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that [tex]y=-\frac{1}{3}x+1[/tex]
3. The line intersects the y-axis at the point (0,4) therefore its y-intercept is b=4.
The line rises up 3 units on the y-axis for every 1 unit on the x-axis therefore the line has a slope of m=3.
Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that [tex]y=3x+4[/tex]
Trapezoids A and B are similar. Find the values of x and y.
Step-by-step explanation:
when 2 shapes are similar, it means that all their angles are the same compared with each other.
and all distances (incl. side lengths) if one shape correlate to the corresponding distances in the other shadow by the same ratio or factor.
we have one side (30 m in A and 50 m in B), where we have both measures.
we see that the ratio to "go" from A to B is 30/50 = 3/5.
that means a distance in A is the same distance in B multiplied by 3/5.
and that factor is the same also for every other side.
therefore,
x = 15 m × 3/5 = 3 m × 3 = 9 m
y × 3/5 = 18 m
3y = 90 m
y = 30 m
A parabola opens to the left. Which could be the equation of the parabola? (x – 4)2 = 4(y 3) (x – 4)2 = –4(y 3) (y – 4)2 = 4(x 3) (y – 4)2 = –4(x 3).
The equation of a leftward parabola is [tex]\rm (y - 4)^2 = -4(x+ 3)[/tex]. Then the correct option is D.
What is the parabola?It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called the focus, and the non-movable line is called the directrix.
The parabola is open to the left.
We know that the equation of the parabola will be in square form.
a. [tex]\rm (x - 4)^2 = 4(y +3)[/tex]
This is an equation of an upward parabola.
b. [tex]\rm (x - 4)^2 = -4(y+ 3)[/tex]
This is an equation of a downward parabola.
c. [tex]\rm (y - 4)^2 = 4(x+ 3)[/tex]
This is an equation of a rightward parabola.
d. [tex]\rm (y - 4)^2 = -4(x+ 3)[/tex]
This is an equation of a leftward parabola.
Thus, the correct option is D.

7a - 8 - 12a + 4 (please give steps)
Answer:
The answer will be -5a-4
Step-by-step explanation:
Subtract 7a-12a=-5a
Add -8+4=-4
which makes the answer -5a-4
Hope this helps:)
Answer:
a = -4/5
Step-by-step explanation:
7a - 8 - 12a + 4
First, you want to put like terms together. You can rearrange the terms because of the Commutative Property.
7a - 12a - 8 + 4
I will put parentheses around the negative numbers, so it is easier to see the negative numbers.
7a (- 12a)( - 8) + 4
Now you combine the Like Terms
7a-12a and -8+4
- 5a - 4
Now you need to get the term with a all by itself on the other side of the equals sign. You can do this by adding the term over to the other side.
-5a - 4
+5a +5a
Now you have
- 4 = 5a
To get the final answer you need to get a all by itself. You can do this by dividing 5 on both sides.
-4/5=5a/5
So you get
-4/5 = a
as your final answer.

Answer:
104 m²
Step-by-step explanation:
Area of the quadrilateral
= width × length
= 10 m × 8 m
= 80 m²
Area of the triangle
= ½ × base × height
= ½ × 8 m × 6 m
= 24 m²
Total area of the shape
= Area of the quadrilateral + Area of the triangle
= 80 m² + 24 m²
= 104 m²

A rectangles perimeter is 124 ft. its length is 2 ft shorter than THREE TIMES its width. use an equation to find the rectangles length and width
Its width is___
its length is____
Answer:
Length will be 46 ft and width will be 16 ft
Explanation:
Let the width be x.
then the length will be 3x - 2
using the rectangle perimeter formula:
2( length + width )
2(x + 3x-2) = 124
2(4x-2) = 124
8x - 4 = 124
8x = 128
x = 16 ft

184.6cm³ up you are rounding to the nearest tenth 184.56cm³ if you are rounding to the nearest hundredth
It's a hemisphere instead of a sphere so the formula is 2/3×π×r³ which gives us the equation of 2/3×π×4.45³ snd the reason we use 4.45 is because the diameter is 8.9 so we have to divide that by 2 to get the radius which is 4.45

4x + 2y = -12 3x + y = -10 please help system by substitution.
Answer:
(-4, 2)
Step-by-step explanation:
4x+2y=-12
3x+y=-10
Start by dividing the first equation by 2 to simplify it...
2x+y=-6
Then, subtract -2x from both sides to isolate y...
y=-2x-6
Substitute -2x-6 for y in the second equation...
3x-2x-6=-10
Combine like terms...
x-6=-10
Add 6 to both sides
x-6+6=-10+6
x=-4
Plug -4 in for x to solve for y:
3(-4)+y=-10
-12+y=-10
Add 12 to both sides
-12+12+y=-10+12
y=2
(x,y)=(-4,2)

Step-by-step explanation:
Use the Distributive Property in order to solve.
Distributive Example:[tex]a(b+c)=ab+ac[/tex]
Using the property into the equation:
[tex]3(3y-9)=3(3y)-3(9)=9y-27[/tex]
[tex]9y-27=0[/tex]
Add 27 to both sides:
[tex]9y=27[/tex]
Divide each side by 9:

Write an equation in slope-intercept form for the line with slope 2 and y-intercept 5. Then graph the line.
Answer:
y = 2x + 5
Step-by-step explanation:
Slope-intercept form: y = mx + b
where:
m is the slopeb is the y-intercept (when x = 0)Given: a line with a slope of 2, and y-intercept of 5
Equation: y = 2x + 5
y-intercept: (0, 5)Randomly select y-values that will help you graph the equation:
when y = -9:
-9 = 2x + 5 [subtract 5 from both sides]
-9 - 5 = 2x
-14 = 2x [divide both sides by 2]
-14 ÷ 2 = 2x ÷ 2
-7 = x
coordinate: (-7, -9)
when y = -5:
-5 = 2x + 5 [subtract 5 from both sides]
-5 - 5 = 2x
-10 = 2x [divide both sides by 2]
-10 ÷ 2 = 2x ÷ 2
-5 = x
coordinate: (-5, -5)
when y = -1:
-1 = 2x + 5 [subtract 5 from both sides]
-1 - 5 = 2x
-6 = 2x [divide both sides by 2]
-6 ÷ 2 = 2x ÷ 2
-3 = x
coordinate: (-3, -1)
when y = 3:
3 = 2x + 5 [subtract 5 from both sides]
3 - 5 = 2x
-2 = 2x [divide both sides by 2]
-2 ÷ 2 = 2x ÷ 2
-1 = x
coordinate: (-1, 3)
With these coordinates, graph them on a coordinate plane and draw a straight line through them. That should be the graph of the equation.
The hypotenuse of a right triangle measures 11 cm and one of its legs measures 9 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
5.5 cm
Step-by-step explanation:
Recall the Pythagorean Theorem which states that [tex]a^2+b^2=c^2[/tex] for a right triangle with side lengths [tex]a[/tex] and [tex]b[/tex], with a hypotenuse of [tex]c[/tex]:
[tex]a^2+b^2=c^2\\\\9^2+b^2=11^2\\\\81+b^2=121\\\\b^2=30\\\\b=\sqrt{30}\\\\b\approx5.5[/tex]
Therefore, the measure of the other leg is about 5.5 cm
