Answer:
A. C = (d-ab)/a
Step-by-step explanation:
a(c + b) = d
a(c + b)/a = d/a
c + b = (d/a)
c = (d/a) - b
a(c + b) = d
ac + ab = d
ac = d - ab
ac/a = d/a - ab/a
c = (d/a) - b
The dimensions of a right triangle are shown in the diagram.
What is the length of the missing side, to the nearest tenth of a centimeter?
Answer:
18.4 cm
Step-by-step explanation:
For this problem, you would use Pythagorean Theorem or a^2+b^2=c^2. Don't forget that the c in the formula is always your hypotenuse or the longest side of the triangle. The a and the b are always the legs of the triangle. (It doesn't matter which leg is which letter) The hypotenuse is also always across from the 90 degree angle. Picture the 90 degree angle as an arrow pointing to the hypotenuse. In this case, the hypotenuse (or c) is 20.7 cm. Now all you have to do is plug and chug! I hope this helps you and thanks for asking your question!!

Answer:
x2 y-32
Step-by-step explanation:
Answer:
[tex]y=224-16x[/tex]
Step-by-step explanation:
Stare at the table for a bit. if you look at the y you can tell that the difference between two rows is the same, and it's equal to 32: every time x increases by 2, y decreases by 32; it means that if x increased by 1, y would decrease by 16. At this point we can write the equation as [tex]y=q-16x[/tex] To find q there are 2 ways: one is to plug the value from any line in place of y and x, or, more elegant, is to backtrack the table: if y goes down by 32 when x raises by 2, it emans that if x decreases by 2, y will go up by 32. And 192+32 is 224, our q value.

Solve the system of equations by elimination:4p + 4q = 44p - 4q = 28
Answer:
p =9
q =2
Step-by-step explanation:
4p + 4q = 44 -----------(I)
4p - 4q = 28 -------------(II)
Add the equations and thus q will be eliminated and we can find the value of p.
(I) 4p + 4q = 44
(II) 4p -4q = 28 {Now add}
8p = 72
p = 72/8
p= 9
Plugin p = 9 in equation (I)
4*9 + 4q =44
36 + 4q = 44
4q = 44 - 36
4q = 8
q = 8/4
q = 2
help pls need help show your solution and then graph
Answer:
Step-by-step explanation:
We can use the quadratic formula or factor, This looks hard to factor so we should use the quadratic formula.
ax^2 + bx + c
so
a=4
b=-9
c=2
you can try it by hand or use this:
https://www.calculatorsoup.com/calculators/algebra/quadratic-formula-calculator.php
you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)
so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis

The sum of two numbers is 88. The larger number is 16 more than the smaller number. What is the smaller number?
Answer: please mark me brainliest
28
Step-by-step explanation:
you half 88 you get to 44 and then you add 16 that is 60. 88 subtract 60 is 28
Solve the following equation

X-5=0
X=5 is the answer
Factorise -x^2-20x-100
Answer:
(x+10)(x+10) or (x+10)^2
Step-by-step explanation:
Divide by -1 first
a=1
b=20
c=100
Since a*c whose sum is b...
1*100=100
10*10=100 and adds to 20
The answer is (x+10)(x+10) or (x+10)^2

Name the
alternate
interior angle
with angle 5.
==================================
Explanation:
We can think of lines L and M as sort of train tracks. Inside the train tracks we have the interior angles of: 3, 4, 5, 6
Angles 3 and 6 are one pair of alternate interior angles. They are on alternate sides of the transversal line N.
The other pair of alternate interior angles are 4 and 5
Alternate interior angles are only congruent when L and M are parallel.
Answer:
Angle 4
Step-by-step explanation:
I believe it's on the opposite side of the transversal so yee

graph the line y=3(x+3)+4
Answer:
Check out the image below the explanation.
Step-by-step explanation:
1. First, let's simplify the equation.
[tex]y = 3(x) + 3(3) + 4[/tex] [tex]y = 3x + 9 + 4[/tex] [tex]y = 3x + 13[/tex]2. Since the equation is y = 3x + 13:
The y-intercept is 13.For every 1 unit we go to the right, we go 3 units up.Now, here's the graph!
2.9. What is the equation of a line parallel to 3x + 4 = y and passing through
(4,-2)?
A. 3x + 10 = y
B. 3x – 14 = y
C. -*-=y
D. --*x+10=y
Hello! (:
3x+4=y
We want to convert it into slope-intercept form:
y=mx+b
Our equation looks like this:
y=3x+4
Now, parallel lines have the same slope. So if one line has a slope of 3, the line parallel to it has a slope of 3 as well.
Now, we have the slope and a point, so we write the equation in point-slope form:
y-y1=m(x-x1)
y-(-2)=3(x-4)
y+2=3x-12
y=3x-12-2
y=3x-14
Hence, that is the required equation, Hope it helps you!
