–19w + 11 = –17w − 19
w=
Please help, will mark brainliest to correct answer!
Answer:
w = 15
Step-by-step explanation:
We have an expression and are asked to solve for w.
-19w + 11 = -17w - 19
Subtract 11 from both sides :
-19w = -17w - 30
Add 17w to both sides :
-2w = -30
Divide -2 from both sides to isolate w :
w = 15

Solve 12x-5>-2 please
Answer:
[tex]x > \frac{1}{4} [/tex]
Step-by-step explanation:
[tex]12x - 5 > - 2[/tex]
Lets add +5 in both the sides.
[tex] = > 12x - 5 + 5 > - 2 + 5[/tex]
[tex] = > 12x > 3[/tex]
Now lets divide 12 on both the sides.
[tex] = > \frac{12x}{12} > \frac{3}{12} [/tex]
[tex] = > x > \frac{1}{4} [/tex]
f(x)=6^x for x=2 help please
9514 1404 393
Answer:
f(2) = 36
Step-by-step explanation:
Put 2 where x is and do the arithmetic.
f(2) = 6^2
An exponent of 2 means 6 is a factor two times.
f(2) = 6×6
f(2) = 36
Answer:
36
Step-by-step explanation:
To evaluate f(x) = 6^x at x = 2, substitute 2 for x:
f(2) = 6^2 = 36
Select all the functions that have no real number solution.
4x^2 + 100 = 0
3x^2 - 9 = 0
x^2+ 1 = 0
6x^2 - 216 = 0
x^2 - 49 = 0

Find the value of the variable(s). If your answer is not an integer, leave it in simplest radical form.
x=10/3 x=10,y=30/3 x=30.y=10/3
Answer:
Use the fact that sin(x) = opp/hyp and tan(x) = opp/adj
where opp=opposite, hyp=hypotenuse, adj=adjacent and recall sin(30)=1/2 and tan(30) = 1/sqrt(3)
sin(30) = 1/2 = 17/y
y = 17(2) = 34
tan(30) = 1/sqrt(3) = 17/x
x = 17sqrt(3)
So the answer is (d)
Note that you could have also use the Pythagorean theorem to find x instead of using tan(30).

3 cups of tea and 4 cups of coffee costs £3.45 in total.
4 cups of tea and 1 cup of coffee costs £2.65 in total.
How much would it costs to buy one cup of each in total?
Answer:
A) 3T + 4C = 3.45
B) 4T + 1C = 2.65 We'll multiply this by -4
B) -16T -4C = -10.60 then we'll add A)
A) 3T + 4C = 3.45
-13T = -7.15
Tea is .55
and coffee is
A) 3 * .55 + 4C = 3.45
4C = 3.45 -(3 * .55)
4C = 1.80
coffee is .45

Determine whether the expression is a polynomial. If it is a polynomial, find the degree
and determine whether it is a monomial, binomial, or trinomial.
2x^-3-4x+1
Answer:
hello again !
this isn't classified as a polynomial because polynomials do not contain variables raised to a negative number, such as this, which is raised to -3.

A whole pizza is cut into 8 pieces and you eat 2 of the 1/8 pieces, how much (in a fraction) is left over? 3/8
4/6
2/8
6/8
Answer:
6/8 is left
Step-by-step explanation:
Hope this helps!! Can I get brainliest please??? :)
8 pieces = 8/8
8/8 - 1/8 - 1/8 = 6/8

Write an equivalent expression by distributing the "-−" sign outside the parentheses: -(-4.2w-7x-5.4)
Answer: 4.2*w + 7*x + 5.4
Step-by-step explanation:
Here we need to remember how the product of different signs works, here is the rule:
(+)*(+) = (+)
(+)*(-) = (-)
(-)*(+) = (-)
(-)*(-) = (+)
Now we want to distribute the negative sign in the equation:
"-(-4.2w-7x-5.4)"
We can write this as:
-(-4.2w-7x-5.4) = (-1)*(-4.2w-7x-5.4)
Now we can distribute the "-1"
Then we get:
(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4)
We have 3 cases where we need to use the "(-)*(-) = (+)" rule, then we get:
(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4) = 4.2*w + 7*x + 5.4
What is the mean of the values in the dot plot?
Enter your answer in the box.
Answer:
The mean is 46.
Step-by-step explanation:
To find the mean of these points add the values together. So that's one 40, two 41's, one 45, two 48's, three 49's and one 50.
40 + (2 * 41) + 45 + (2 * 48) + (3 * 49) + 50
Multiply what's in the parentheses.
40 + 82 + 45 + 96 + 147 + 50
Add, going from left to right
122 + 45 + 96 + 147 + 50
167 + 96 + 147 + 50
263 + 147 + 50
410 + 50
460
Now, divide that by how many dots there were (10).
460/10
The mean of the values in this dot plot is 46.

Simplify the expression -(6 - 4p)
Hey there!
The answer to your question is [tex]-6+4p[/tex]
Given:
[tex]-(6-4p)[/tex]
First, we distribute the negative sign to both terms ([tex]6[/tex] [tex]and[/tex] [tex]-4p[/tex]) This would make the [tex]6[/tex] negative and the [tex]-4p[/tex] positive, so we have:
[tex]-6[/tex] [tex]and[/tex] [tex]4p[/tex]
Add them together and we get:

What is a slope in mathematical terms
Answer:
"The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x)."
Answer:
It is how steep a linear graph/function is.
Step-by-step explanation:
It is the m in the formula y=mx+b. The bigger the member the steeper.
