Answer:
-x + 23
Step-by-step explanation:
you add like terms together, so 2x - 3x = -x
then 15+8 is 23
so you're left with -x+23
F(x)=x^2 - 4x; find f (5)
Answer:
f(5) = 5
Step-by-step explanation:
F(x)=x^2 - 4x
Let x = 5
F(5)=5^2 - 4*5
= 25 - 20
= 5

What is the value of x?
Answer:
x=23
Step-by-step explanation:
A and D are equal to eachother so you write the equation (x-4)=19. To solve all you have to do is add 4 to each side and you will get the answer of x=23
Simplify ^3 sq try (-0.05)^24
Answer:
As
[tex]\sqrt[3]{\left(-0.05\right)^{24}}=0.05^8[/tex]so option D is correct.
Step-by-step explanation:
Given the expression
[tex]\sqrt[3]{\left(-0.05\right)^{24}}[/tex]
[tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a}=a^{\frac{1}{n}}[/tex]
[tex]\sqrt[3]{\left(-0.05\right)^{24}}=\left(\left(-0.05\right)^{24}\right)^{\frac{1}{3}}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc}[/tex]
[tex]=\left(-0.05\right)^{24\cdot \frac{1}{3}}[/tex]
[tex]=\left(-0.05\right)^8[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(-a\right)^n=a^n,\:\mathrm{if\:}n\mathrm{\:is\:even}[/tex]
[tex]=0.05^8[/tex]
Hence, the simplification will be:
[tex]\sqrt[3]{\left(-0.05\right)^{24}}=0.05^8[/tex]
Therefore, option D is correct.
Answer:B.(-0.05)^8

Given the diagram below, find the value of x and find m<2
Answer:
x= 15, m<2= 50
Step-by-step explanation:
5x+55 and 2x+100 are equal
5x+55=2x+100
5x=2x+45
3x=45
x=15
Plug it into 5x+55
5(15)+55 = 130
^That angle and <2 are supplementary, so they need to= 180
130+ m= 180
m<2= 50
Find m/1 and m/2 and it is 130 percent on the other side just look at the pick I can’t explain it
Answer:
angle 1 = 50
angle 2 = 130
Step-by-step explanation:
well, angle 2 and 130 are equal to one another since they're alternate exterior angles.
Angles 1 and 2 are supplementary angles, which equals 180 degrees.
due to angle 2 and 130 being equal, 2 is 130.
subtract 130 from 180 and it gives you 50, which is the answer to angle 1.

What is the equation for the points (-2,3) (1,9) on a graph
9514 1404 393
Answer:
y -9 = 2(x -1) . . . point-slope formy = 2x +7 . . . . slope-intercept form2x -y = -7 . . . . standard formStep-by-step explanation:
Perhaps you want the equation of the line that goes through these two points.
The slope of the line can be found using the formula ...
m = (y2 -y1)/(x2 -x1)
m = (9 -3)/(1 -(-2)) = 6/3 = 2
We can use one of the points to write the equation in point-slope form:
y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)
For slope 2 and point (1, 9) the equation is ...
y -9 = 2(x -1) . . . . equation in point-slope form
__
We can eliminate parentheses and get y by itself to put the equation into slope-intercept form.
y -9 = 2x -2
y = 2x +7 . . . . . . equation in slope-intercept form
__
With a little further rearranging, we can put this into standard form. We can get that by adding -7-y to both sides of the equation.
2x -y = -7 . . . . . equation in standard form
Which is the equation of a line that has a slope of 1/2 and passes through point (2, -3)?
y = 1/2x - 4
y = 1/2 X-2
y = 1/2 x + 2

Frank is going to an amusement park that costs $36.00 to get into. Treats, like cotton candy, caramel apples, and funnel cakes cost $4.00 each. Frank does not want to spend more than $52.00 in all. Solve for x, where x equals the number of $4.00 treats Frank can buy.
4x + $36.00 ≤ $52.00
Answer: x=<4
Step-by-step explanation:
Nola spent $13 on a personal pizza and some wings. If the personal pizza cost $4 and each basket of wings cost $3 then how many baskets of wings did he buy?
Subtract the price of the pizza from the total then divide by the cost of a basket:
13 -4 = 9
9/3 = 3
He bought 3 baskets of wings.

Find the slope of the line that passes through the points (1, 1) and (7, 5).
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=5-1/7-1
m=4/6
m= 2/3
The slope is 2/3
Answer:
2/3
Step-by-step explanation:
To find the slope of a line between two points, you would use the formula
Δ[tex]\frac{y}{x}[/tex]
[tex]\frac{y2-y1}{x2-x1}[/tex] is also the same thing
so, [tex]\frac{5-1}{7-1} = \frac{4}{6} = \frac{2}{3}[/tex]

Step-by-step explanation:
A nutrition bar includes fat and protein in the ratio of 3:5. There are a total of 24 grams of fat and protein combined in the bar. If there are 9 calories per gram of fat and 4 calories per gram of protein, how many calories from fat and how many calories from protein are in the nutrition bar?
Let, amount of fat is 3x .
So, amount of protein is 5x .
It is given that sum of fat and protein is 24 grams.
3x + 5x = 24
8x = 24
x = 3 grams
Amount of fat is, F = 3×3 = 9 grams .
Amount of protein is, P = 5×3 = 15 grams.
Calories in fat, F = 9×9 = 81 calories .
Calories in protein, P = 15×4 = 90 calories .
Therefore, calories from fat and protein is 81 and 90 respectively.
Hence, this is the required solution.

A rectangular picture frame is 3inches wide by 5 inches long.
Tamara needs a larger picture frame that is 12 inches wide, how
long must the picture frame be so that is proportional to the
smaller frame?
Answer:
20in
Step-by-step explanation: If the smaller frame is 3 by 5in long then the larger frame will by 12 by 20in becuase 3*4=12 so 5*4=20
3/4=12/40
Answer: 20 inches long.
Step-by-step explanation:
The Rectangular frame which Tamara already has is 3 inches by 5 inches. The larger one happens to be 12 inches by X inches. We can find the scale of the new Frame by dividing the new value we are provided with by the initial one. In this case, 12 (large frame) divided by 3, or 4. This means that the dimensions of the large Frame are 4 times greater than the smaller one. If this is to be the case, the length is 4 times larger than the original, and 5 x 4 = 20.
