Answer:
Let's solve for x.
2x+3y=6
Step 1: Add -3y to both sides.
2x+3y+−3y=6+−3y
2x=−3y+6
Step 2: Divide both sides by 2.
2x 2 =
−3y+6
2 x= −3
2 y+3
Answer:
x= −3 2

Find the range of f(x) = –2x – 5 for the domain {–2, –1, 1, 2}.
A. {–1, –3, 7, 9}
B. {1, 3, 5, 7}
C. {–1, –3, –7, –9}
D. {–1, –3, 3, 5}
Answer: C) [-1,-3,-7,-19]
Step-by-step explanation:
Range = {-2(-2) - 5, -2(-1) - 5, -2(1) - 5, -2(2) - 5} = {4 - 5, 2 - 5, -2 - 5, -4 - 5} = (-1, -3, -7, -9}
Answer:
-2(-2)-5= -1 -2(-1)-5=-3 -2(1)-5=-7 -2(2)-5=-9... A. {-1, -3, 7, 9}
Step-by-step explanation:
By substituting each value of the domain of x in the function and solving it we will get the range of the function for respective domain
The given function is :
f(x) = -2x - 5
For x = -2 , f(x) is:
f(-2) = (-2*-2) - 5 = 4 - 5 = -1
For x = -1, f(x) is :
f(-1) = (-2*-1) - 5 = 2 - 5 = -3
For x = 1 , f(x) is
f(1) = (-2*1) - 5 = -2 -5 = -7
For x = 2, f(x) is
f(2) = (-2*2) - 5 = -4 -5 = -9
The range is -1 , -3 , -7 , -9
Hope this helps ..!!

Answer:
b, d
Step-by-step explanation:
When you're taking the cube root, the thing you're taking the cube root of is best expressed as a cube.
You know that 2^3 = 8 and 3^3 = 27, so any other representation of 8 or 27 is irrelevant to the problem.
The appropriate choices are the second and fourth ones (B, and D).
what is the degree of the function f(x)=x⁴-5x+8+x²?
First put it in decreasing power according to x.
x^4-5x+8+x^2
=x^4+x^2-5x+8
Now this question is asking what is the highest degree of x you see in this function.
4 of course.
Therefore the answer to his question is degree of 4.

I’m studying and I have trouble with this problem and I need an explanation. Please help me! Thank you
Answer:
Step-by-step explanation:
Im going to assume they want x+108.
You have 2 expressions sitting on a line, so when added to each other they must = 180
So add and set up an equality
x+108+x+78=180
Combine like terms
2x+186=180
Solve
2x+186=180
-180 -180
2x+6=0
-6 -6
2x=-6
________
2
x=-3
Substitute X for -3
-3+108=
105.

PLZZZ HELP ME...I AM FAILING THIS CLASS..if you can help me with ANY of these please do...i need all the work of how you got that answer..thankyou so much!!!
Answer:
Step-by-step explanation:
Hi! I'm lazy but I'll explain number two so you get the concept. 2x + y =10
Well, It says x = 5. When a number is next to another number like this: 5(6), it means multiplication. Same when a number and a letter are together like this: 2x. So that means it's 2 times 5, since 5 = x. 2 times 5 is 10. So what plus 10 equals 10 (10 + y = 10) The answer now is obviously 0. So that's how you do those equations! Hope u understand lol :>
y = 5х – 7
—3х – 2 y = -12
[tex]-3x-2(5x-7)=-12\\-3x-10x+14=-12\\-13x=-26\\x=2\\\\y=5(2)-7\\y=10-7\\y=3[/tex]
Answer:
[tex](x, y) = (-\frac{29}{2}, -12)[/tex]
Step-by-step explanation:
[tex]-12 = 5 x ( -\frac{29}{2} ) - 7 - 3 x ( -\frac{29}{2} ) - 2 x (-12) = -12[/tex]
plz answer. Its urgent. thanks
Answer:
[tex] a = \dfrac{5}{18} [/tex]
[tex]b = -\dfrac{1}{18}[/tex]
Step-by-step explanation:
You need to rationalize the fraction.
[tex] \dfrac{1}{5 + \sqrt{7}} = a + b\sqrt{7} [/tex]
[tex] \dfrac{1}{5 + \sqrt{7}} \times \dfrac{5 - \sqrt{7}}{5 - \sqrt{7}} = a + b\sqrt{7} [/tex]
[tex] \dfrac{5 - \sqrt{7}}{25 - 7} = a + b\sqrt{7} [/tex]
[tex] \dfrac{5 - \sqrt{7}}{18} = a + b\sqrt{7} [/tex]
[tex] \dfrac{5}{18} - \dfrac{1}{18}\sqrt{7} = a + b\sqrt{7} [/tex]
[tex] a = \dfrac{5}{18} [/tex]
[tex]b = -\dfrac{1}{18}[/tex]
A plant currently measures 5.5 inches tall and will grow at a rate of 1 inch per week. Andrew wants to graph this information for his Science Fair project. If x represents the number of weeks and y represents the height of the plant, which choice below correctly describes the y-intercept in this relationship?
(5.5, 0)
(0,1)
(0, 5.5)
(1, 5.5)
Answer:
0, 5.5
Step-by-step explanation:
when they ask for a y-intercept, x is always zero, so now we eliminate two of the answers, and we will only have (0, 1) or (0, 5.5). At the beginning of the question it said a plant is currently at 5.5, so it started as 5.5 (0, 5.5)
so THE ANSWER IS (0, 5.5)
