Answer:
x= -6
y= -5
Step-by-step explanation:
(x,y) = (-6, -5)
Answer:
(-6,-5)
x=-6
y=-5
Step-by-step explanation:
9x-7y=-19
5x-3y=-15
When solving with elimination, you multiply both equations by a number to get two terms to cancel each other out.
We can try to get the y's to cancel out. The LCD of 7 and 3 is 21, so we multiply one equation by 3 and another by -7 (to get one -21y and one 21y)
{9x-7y=-19}*3=
27x-21y=-57
{5x-3y=-15}*(-7)=
-35x+21y=105
Now, we combine the two equations.
27x-21y=-57
-35x+21y=105
-8x=48
Now, solve for x.
-8x=48
x=-6
Now we can plug x into one of the original equations to get y.
I will use 9x-7y=-19.
9(-6)-7y=-19
-54-7y=-19
Add 54 to both sides.
-7y=35
y=-5
We can put these values into an ordered pair: (-6,-5).
A triangle is 4 cm wider than it is tall. The area is 16 cm2. Find the height and the base.

Hello!
To find the angles of this triangle, we would look at the markings and angle measurements that are already on the triangle.
We see on the top triangle that the sides are congruent. That means angle 1 and 2 are the same. To find those angles, we would subtract 55 from 180, then divide by 2.
180 - 55 = 125
125 ÷ 2 = 62.5
Angle 1: 62.5
Angle 2: 62.5
We see angle 3 is opposite of 55. These two angles are congruent by the vertical angles theorem.
Angle 3: 55
On the bottom left of the bottom triangle, we see the angle 105 that is supplementary to the angle 4. These angles are supplementary angles, in which they will add up to 180. To find angle 4, we subtract 105 from 180.
180 - 105 = 75
Angle 4: 75
We know that triangles' angles add up to 180, so to find angle 5, we subtract angle 3 and angle 4 from 180, and we can do this because of the Triangle Angle Sum Theorem.
180 - 55 - 75 = 50
Angle 5: 50
Angle 1: 62.5
Angle 2: 62.5
Angle 3: 55
Angle 4: 75
Angle 5: 50

Form quadratic functions using the following properties: f(2)=f(4)=0 and f(3) = -2
Answers
9514 1404 393
Answer:
f(x) = 2x^2 -12x +16
Step-by-step explanation:
The zeros tell you the factored form is ...
f(x) = a(x -2)(x -4)
Then f(3) is ...
f(3) = -2 = a(1)(-1) = -a
a = 2
So the factored function is ...
f(x) = 2(x -2)(x -4)
Expanded to standard form, we get ...
f(x) = 2x^2 -12x +16

What is the asymptote for the function?
I tried to do it but I can’t
Answers
Answer:
Horizontal Asymptote → y = 17
Step-by-step explanation:
Given function is f(x) = [tex]\frac{2}{5}(16)^{x+13}+17[/tex]
Here, the parent function is g(x) = [tex]\frac{2}{5}(16)^x[/tex]
Parent function has a horizontal asymptote as y = 0
If the function g(x) is shifted 13 units left and 17 units up, new function will be f(x) = [tex]\frac{2}{5}(16)^{x+13}+17[/tex]
When the parent function is shifted 17 units up, horizontal asymptote shifts 17 units upwards.
Therefore, horizontal asymptote of the image function becomes y = 17.

__________________
We have the expression 80 less than x. X has no artifical value therefore we do nothing with it. Based off of the wording of the sentence, it says that the total of this unknown number is 80 less than x. Meaning the 80 has been subtracted by x to get this unknown number. Therefore,

Able is carving a rectangular pyramid clock out of green quartz. The length of the rectangle base is 14 cm and the height of the clock is 9cm. If the clock needs to have a volume of 168cm3 what is the width of the base
Answers
Answer:
14cm
Step-by-step explanation:
Volume of the pyramid = Base area × height/3
V = BH/3
Base area = 14×width
Height= 9cm
Volume = 168cm³
Substitute into the formula
168 = 4w×9/3
36w = 168×3
36w = 504
w = 14cm
Hence the width of the pyramid is 14cm

Answers
Answer: 457.3
Step-by-step explanation:
[tex]V=\frac{lwh}{3}[/tex]
[tex]V=\frac{14*14*7}{3}[/tex]= 457.3
Answer:
V= 1568 in^3
Step-by-step explanation:
B = 14^2 = 196
896 = 14^2 + 2(14) (l)
896 = 196 + 28 (l)
700 = 281 l
25 = l
7^2 + b^2 = 25^2
49 = 625
24
1/3 (196)(24) = 1568

Answers
Answer:

Point C is the centroid.
Property of centroid: the medians are divided in 2:1 ratio from the vertices.
SD = 21SC = 2/3*21 = 14Answer:
SC = 14 units
Explanation:
Centroid of a triangle refers to the point where it's 3 median intersect. It's the centre point of the triangle.
the point of intersection divides all three median into two parts. the parts are in ratio 2 : 1. The part of the median starting from the vertex to the midpoint is 2/3rd of the median.
SD = 21
SC = 2/3 of 21
= 2/3 × 21
