solve for x 2x+5=17 plzhelp
x = 6
you have to work out the problem and what ever you do to one side, you do to the other
Answer:
x=6
Step-by-step explanation:
2x+5=17
Subtract 5 from both sides;
2x+5-5=17-5
Simplify
2x=12
Divide both sides by 2;
2x/2=12/2
Simplify;
x=6

the graph of h is the graph of f(x)=x^2 translated 4 units left and 7 units down. Write the function H in vertex form.
Answer:
f(x)=a(x - h)2 + k
Much like a linear function, k works like b in the slope-intercept formula. Like where add or subtract b would determine where the line crosses, in the linear, k determines the vertex of the parabola. If you're going to go up 2, then you need to add 2.
The h determines the movement horizontally. what you put in h determines if it moves left or right. To adjust this, you need to find the number to make the parentheses equal 0 when x equals -2 (because moving the vertex point to the left means subtraction/negatives):
x - h = 0
-2 - h = 0
-h = 2
h = -2
So the function ends up looking like:
f(x)=a(x - (-2))2 + 2
Subtracting a negative cancels the signs out to make a positive:
f(x)=a(x + 2)2 + 2
Step-by-step explanation:
The translated value of the function is h ( x ) = ( x + 4 )² - 7
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x²
we can obtain the function h(x) by first translating it 4 units to the left, which gives us f(x + 4), and then translating it 7 units down, which gives us f(x + 4) - 7. Therefore, the function h(x) can be written as:
h(x) = f(x + 4) - 7
To write this in vertex form, we need to complete the square. First, we have:
h(x) = f(x + 4) - 7
h(x) = (x + 4)² - 7
This is the vertex form of the equation for h(x). The vertex of the parabola is at the point (-4, -7), which is obtained by setting x + 4 = 0 in the equation above.
The value of the vertex is -7, which is obtained by subtracting 7 from the squared term.
Therefore, the vertex form of the equation for h(x) is:
h ( x ) = ( x + 4 )² - 7
Hence , the transformed function is h ( x ) = ( x + 4 )² - 7

Answer:
9.) I 5/14 * 4/13 10.) H 45
Step-by-step explanation:
For 9.) the probability the first time to get a red marble is 5/14 because there are 5 red marbles and 14 total marbles. The probability the second time she picks, if a green one was chosen, one is 4/13 because one green marble needs to be missing and because one marble is missing 14-1=13 so there are 13 total marbles. You would multiply the two probability (5/14 and 4/13) to find the probability of drawing two green marbles in a row
For 10.) I found that 2/5= .4 and 5/8= .625 so I multiplied both fractions by 200
.4 * 200= 80
.625 * 200= 125
These are the numbers of games both people won
Subtract the two and you get 125-80= 45 which is how many more games Tyrell would win.

The top of the Washington Monument is a triangular pyramid with a triangular base. Each triangular face is 24 feet high with a base that is 16 feet wide. The lateral faces of the pyramid are covered with white marble. About how many square feet of marble cover the lateral faces of the pyramid
Answer:
3944ft^2
Step-by-step explanation:
o 4 triangular faces of the pyramid will have total area
= 4 ×12 × base × height = 4 × 12 × 34 × 58ft^2 = 3944ft^2
So 3944ft^2 of marble cover the faces of the pyramid.

The American Civil War (also known by other names) was a civil war in the United States from 1861 to 1865, fought between northern states loyal to the Union and southern states that had seceded to form the Confederate States of America. The principal cause of the war was the status of slavery in the United States, especially in the territories. After Abraham Lincoln won the November 1860 presidential election on an anti-slavery platform, an initial seven slave states declared their secession from the country to form the Confederacy. War broke out in April 1861 when secessionist forces attacked Fort Sumter in South Carolina, just over a month after Lincoln's inauguration. An additional four slave states joined the Confederacy in the following two months. The Confederacy grew to control at least a majority of territory in those eleven states (out of the 34 U.S. states in February 1861), and it claimed the additional states of Kentucky and Missouri by assertions from native secessionists fleeing Union authority. These states were given full representation in the Confederate Congress throughout the Civil War. The two remaining slave states, Delaware and Maryland, were invited to join the Confederacy, but Delaware declined and nothing substantial developed in Maryland due to intervention by federal troops. The Confederate states were never diplomatically recognized as a joint entity by the government of the United States, nor by that of any foreign country. The states that remained loyal to the U.S. were known as the Union. The Union and the Confederacy quickly raised volunteer and conscription armies that fought mostly in the South for four years. Intense combat left between 620,000 and 750,000 soldiers dead, along with an undetermined number of civilians. The Civil War remains the deadliest military conflict in American history, and accounted for more American military deaths than all other wars combined until the Vietnam War.

Step-by-step explanation: it would be josh has 2 jars of jelly
The number of coins in the red jar is 83 and the number of coins in the red jar is 110.
How to find the equation of the words problem?The blue jar has 27 more coins than the red jar. There are total of 193 coins.
The number of coins in each jar can be calculated as follows:
Using equation,
let
x = coins in the red jar
Therefore,
coins in the blue jar = 27 + x
Therefore,
total coins in the jars = x + 27 + x
193 = x + x + 27
193 - 27 = 2x
166 = 2x
divide both sides by 2
x = 166 / 2
x = 83
Therefore,
number of coins in the red jar = 83
number of coins in the blue jar = 83 + 27 = 110
