in triangle ABC shown, DE || AC. What is the length of AC?
Answer:
AC = 20
Step-by-step explanation:
Δ BDE and Δ BAC are similar, so the ratios of corresponding sides are equal, that is
[tex]\frac{AC}{DE}[/tex] = [tex]\frac{BA}{BD}[/tex] , substitute values
[tex]\frac{AC}{8}[/tex] = [tex]\frac{10}{4}[/tex] ( cross- multiply )
4AC = 80 ( divide both sides by 4 )
AC = 20
In the triangle ABC if DE is parallel to AC then the length of AC is 12 units.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Given that the triangles ABC and BDE are similar triangles.
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
Let us form a proportional equation by comparing the proportional sides.
AC/DE=AD/BD
AC/8= 6/4
Apply cross multiplication
AC=48/4
Divide numerator and denominator by 4.
AC=12
Hence, in the triangle ABC if DE is parallel to AC then the length of AC is 12 units.

Use the figure to find the measures of the numbered angles.
1 = 61° because it is a corresponding angle to angle 6
2 = 119° because it is an alternate exterior angle to angle 7
3 = 61° because it is an alternate angle to angle 1
4 = 119° because it is an alternate angle to angle 2
5 = 119° because it is an alternate angle to angle 7
6 = 61° because is is an alternate angle to 61°
7 = 119° because it and 61° are supplementary angles (total 180° together)
Answer:
1 = 61° because it is a corresponding angle to angle 6
2 = 119° because it is an alternate exterior angle to angle 7
3 = 61° because it is an alternate angle to angle 1

Is (6, 1) a solution to the inequality 11x + 3y > 4?
Answer:
Yes (6,1) is a solution to the inequality
Step-by-step explanation:
Plug in the coordinate point and check:
11(6)+3(1)>4?
66+3>4?
69>4
Since 69 is indeed greater than 4, then (6,1) is a solution to the inequality.

Step-by-step explanation:
Graph the equation y=-x^2-12x-35y=−x 2−12x−35 on the accompanying set of axes. You must plot 5 points including the roots and the vertex.
please help and explain I'm very confused and I have no idea what to do.
The graph of y=-x^2-12x-35 is attached and it has x intercepts at x=-7 and x=-5 and vertex is at (6, -107).
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
To graph the equation y=-x^2-12x-35, we can start by finding the x-intercepts (or roots) and the vertex of the parabola.
To find the x-intercepts, we can set y=0 and solve for x:
0 = -x² - 12x - 35
Using the quadratic formula, we get:
x=-b±√b²-4ac/2a
x=12±√144-140/2(-1)
x=12±√144-140/(-2)
x=12±2/(-2)
The x-intercepts are approximately x=-7 and x=-5
To find the vertex, we can use the formula x=-b/2a to get the x-coordinate, and then substitute it into the equation to get the y-coordinate:
x = -b / 2a = -(-12) / 2(-1) = 6
y = -x² - 12x - 35 = -(6)^2 - 12(6) - 35 = -107
So the vertex is at (6, -107).
Hence, the graph of y=-x^2-12x-35 is attached and it has x intercepts at x=-7 and x=-5 and vertex is at (6, -107).

Step-by-step explanation:
Substitute the value (p(11)) into the function and evaluate by solving. Do not forget to follow the order of operations. The order of operations is the steps one must do operations in an equation in order to get a valid result, they are the following,
1. Parenthesis
2.Exponent/Radicals
3.Multiplication/Division
4.Addition/Subtraction
[tex]p(x)=5(x^2+1)+16[/tex]
Substitute,
[tex]p(11)=5((11)^2+1)+16[/tex]
Simplify,
[tex]p(11)=5(121+1)+16[/tex]
[tex]p(11)=5(122)+16[/tex]

0.9x+2.3x = -6.4 Find x on both sides of the problem, a little confused... Would we combine the like terms on the left side?
Answer:
-2
Step-by-step explanation:
0.9x+2.3x = -6.4
Add the two values of the left side of the equation together
3.2x = -6.4
Divide both sides of the equation by 3.2
x = -6.4 / 3.2
x = -2

solve 2x + 3y = 4 - 2x - y = -8
Answer:
y = -2 and x = 5
Step-by-step explanation:
2x + 3y = 4
-2x - y = -8
Since this is a system of equations, we can either substitute or subtract. I will be subtracting.
2x + 3y - 2x - y = 4 - 8
2y = -4
y = -2
Now that we have y, we will plug it in for the first equation and solve.
2x + 3(-2) = 4
2x - 6 = 4
+ 6 + 6
2x = 10
x = 5
