Find the x-intercept and y-intercept of the line.
4x + 5y = -20
-intercent:
10
Answer:
y-intercept is (0, -4)
x-intercept is (-5, 0)
Step-by-step explanation:
Remember the x-intercept and the y-intercept are the points on the graph where the line crosses the x-axis and the y-axis respectively.
We can find the x intercept and the y intercept a couple of ways. One way is to graph the line, which I will do later. The other way is to do a little math.
The equation of a line in y-intercept form is
[tex]y = mx + b[/tex]
where b = the y-intercept
In our equation above and solving for y we get the y-intercept is -4
[tex]4x + 5y = - 20 \\ 5y = - 4x - 20 \\ y = - \frac{4}{5} x - 4[/tex]
Doing more algebra and solving for x we get the x intercept is negative 5.
[tex]y = - \frac{4}{5} - 4 \\ y + 4 = - \frac{4}{5} x \\ x = - \frac{5}{4} y - \frac{20}{4 } \\ x = - \frac{5}{4} y - 5[/tex]

CAN SOMEONE HELP ME WITH THIS QUESTION!!!
Answer:
E
Step-by-step explanation:
let a, b, c represent the number of students in 6th, 7th, 8th grade
ratio of students : teachers = 28 : 1
There are 82 teachers , so 28 × 82 = 2296 students
Then
a + b + c = 2296 , that is
828 + b + c = 2296 ( subtract 828 from both sides )
b + c = 1468 → E

find the measure of the indicated angle
Answer:
∠ E = 57°
Step-by-step explanation:
Since DF = EF then the triangle is isosceles with 2 base angles congruent , so
∠ E = ∠ D = 4x + 1
The sum of the 3 angles in the triangle = 180°
Sum the 3 angles and equate to 180
4x + 1 + 4x + 1 + 5x - 4 = 180 , collect like terms
13x - 2 = 180 ( add 2 to both sides )
13x = 182 ( divide both sides by 13 )
x = 14
Then
∠ E = 4x + 1 = 4(14) + 1 = 56 + 1 = 57°
Write the equation of the line in fully simplified slope intercept form
Answer:
y = 6x - 5
Step-by-step explanation:
In order to determine the slope-intercept form, y = mx + b, of the given line:
You need to find the slope (m) and determine the y-intercept (b).
Given the points (1, 1) and (0, -5):
Let (x1, y1) = (1, 1)
(x2, y2) = (0, -5)
Use the following formula for slope:
m = (y2 - y1)/(x2 - x1)
m = (-5 - 1)/(0 - 1)
m = -6/-1
m = 6
The slope of the line is 6.
Next, the y-coordinate (b) of the point, (0, b ) is the y-intercept of the line where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.
Looking at the graph, you'll see that the line crosses at point (0, -5). We used this point earlier to solve for the slope. Hence, the y-coordinate, b = -5, is the y-intercept.
Given the slope, m = 6, and the y-intercept, b = -5:
The linear equation in slope-intercept form is: y = 6x - 5.

A circle has a radius of \blue{3}3start color #6495ed, 3, end color #6495ed. An arc in this circle has a central angle of 340^\circ340
∘
340, degrees.
What is the length of the arc?
Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi and enter your answer as a decimal.
Answer:
length of arc ≈ 17.8 (to the nearest tenth)
Step-by-step explanation:
To find the length of the arc we use the formula for finding length of an arc.
length of arc = ∅/360 × 2πr
where
∅ = central angle
r = radius
∅ = 340°
r = 3
length of arc = ∅/360 × 2πr
length of arc = 340/360 × 2 × π × 3
length of arc = 340/360 × 6π
length of arc = 2040π/360
length of arc = 204π/36
length of arc = (204 × 3.14)/36
length of arc = 640.56/36
length of arc = 17.7933333
length of arc ≈ 17.8 (to the nearest tenth)
