you need to state the value of bo
Answer: f(-9)= 243
Step-by-step explanation:
f(x) = 4x²+7x -18
f(-9) = 4(-9)²+7(-9)-18
= 4(81) -63-18
= 324- 81
= 243

Answer:
Measure of fourth angle of quadrilateral is:
100
Step-by-step explanation:
We know that the sum of angles in a quadrilateral is 360°
Three of the angles of a quadrilateral are 120 48 and 92
we have to find the sum of the fourth angle of the quadrilateral
Let measure of fourth angle be x
120+48+92+x= 360
i.e. 260+x = 360
Subtracting both sides by 260, we get
x= 100
Hence, Measure of fourth angle of quadrilateral is:
100

Answer:
if your looking for z it is 5/8k+2.375

Answer:
Step-by-step explanation:
Please, include the instructions.
I'm assuming you want to solve this system of linear equations for z and w, assuming that k is an unknown constant.
Use the method of elimination by addition and subtraction. To eiiminate w, multiply all four terms of the first equation by 10, obtaining:
10 z + 10w - 30 = 10k
6z - 10 w = 80
Then 16z - 30 - 80 = 10k, or
16z -110 = 10k, Simplifying this, we get:
10(k + 11)
z = ---------------
16
Substituting this expression for z into the first equation, we get:
(10/16)(k + 11) + w - 3 = k. We must solve this for w:
-(10/16)(k + 11) + w - 3 = k), or
-(10/16)(k + 11) - w + 3 = -k
Then -(10/16)(k + 11) + 3 + k = w
and so the solution, in terms of the unknown constant k, is
10(k + 11)
( --------------, -(10/16)(k + 11) + 3 + k )
