Answer:
d) x-intercepts are –3 and –5; vertex is (–4, 1)
Step-by-step explanation:
parabola are the vertex findings -4
we find these using formula m +n / 2
m+ n = -3 -5 / 2 = -4
m+n / 2 = -8/2 = -4
xv = -4
plug in -4 to find yv
(x+5)
(-4 + 5)
yv = 1

Step-by-step explanation:
Solution:
a. when e = 11 and f = 7
[tex] \\ \: \: \frac{e + 5}{4f - 4} [/tex]
[tex] \\ = \frac{11 + 5}{4 \times 7 - 4} [/tex]
[tex] \\ = \frac{11 + 5}{28 - 4} [/tex]
[tex] \\ = \frac{16}{24} [/tex]
[tex] \\ = { \cancel \frac{16}{{24}}}[/tex]
[tex] \\ = \frac{2}{3} [/tex]
b. when e = -1 and f = -4
[tex] \\ \: \frac{e + 5}{4f - 4} [/tex]
[tex] \\ = \frac{{ - 1 + 5} }{4( - 4) - 4} [/tex]
[tex] \\ = \frac{ - 1 + 5}{ - 16 - 4} [/tex]

The weight of the of an object to is equal to 3/4 of its own weight plus 3/4 of a pound.
How much does the object weigh? Explain.
Answer:
[tex]x=\frac{3}{7} lbs[/tex]
Step-by-step explanation:
[tex]x=\frac{3}{4}(x)+\frac{3}{4}[/tex]
[tex]x+\frac{3}{4}(x)=\frac{3}{4}[/tex]

suppose triangle ABC is reflected over the y-axis. if the distance between point B and the y-axis is 5, what is the distance between the y-axis and B'.
A. 5 units
B. 10 units
C. 2.5 units
D. 1.25 units
Needs to be answered quickly
Answer:
A. 5 units
Step-by-step explanation:
When you reflect any shape over the y-axis, each point's distance from the y-axis will stay the same after it's reflected. Hopefully this helps!
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)

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.

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

escribe el enunciado de las siguientes expresiones algebraicas
Answer:
la familia es cristiana por algebraicasfind 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°
