What number is represented by 4x2+17x+2if x=10?
Answer:
4x²+17x+2=52
Step-by-step explanation:
Step-by-step explanation: The given equation is 4x2 +17x+2. Here, lets substitute the value of x = 10. So, the equation simplifies to 4× (10)²+17(10)+2 , = (4 x 100) + 170 + 2 = 400 + 170 + 2 = 572 So, at x = 10, 4x²+17x+2=52

Is the relationship shown by the data linear? If so, model the data with an equation.
A. The relationship is linear; y + 7= 1/2(x - 5).
B. The relationship is linear; y - 5= -1/2(x + 7).
C. The relationship is not linear.
D. The relationship is linear; y – 5 = 2(x + 7).
Answer:
D. The relationship is linear; y – 5 = 2(x + 7).
Step-by-step explanation:
The correct answer is:
The relationship is linear, and the equation is
y-5 = 2(x+7).
Explanation:
To determine if the relationship is linear, we find the slope between each pair of points. Slope is given by the formula:
The slope between the first two points is given by:
The slope between the second pair of points is given by:
The slope between the third pair of points is given by:
Since the slope is the same throughout the data, the relationship is linear and the slope is 2.
To write the equation, we use point-slope form, which is:
y-y₁ = m(x-x₁)
Using the first point, we have:
y-5 = 2(x--7)
y-5 = 2(x+7)
The answer is The relationship is linear; y - 5 = 2(x + 7).

So I have this question I cannot figure out 3w+w2+1=10−w
Answer:
Answer: w is 1.6 or. -5.6
Step-by-step explanation:
• I guess the question asks to find the value of w
[tex]{ \rm{3w + {w}^{2} + 1 = 10 - w }}[/tex]
• arrange the equation in a quadratic equation format. i.e; ax² + bx + c = 0
[tex]{ \rm{ {w}^{2} + (3w + w) + 1 - 10 = 0 }} \\ \\ { \rm{ {w}^{2} + 4w - 9 = 0 }}[/tex]
• let's solve the equation using the quadratic formular
[tex] \hookrightarrow \: { \tt{w = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a} }} \\ [/tex]
a is 1b is 4c is -9• Substitute following the mathematical operation rules:
[tex]{ \rm{w = \frac{ - 4 \pm \sqrt{ {4}^{2} - (4 \times 1 \times - 9) } }{(2 \times 1)} }} \\ \\ { \rm{w = \frac{ - 4 \pm \sqrt{52} }{2} }}[/tex]
• split the result:
[tex]{ \rm{either \: \{w = \frac{ - 4 + \sqrt{52} }{2} \} \: \: or \: \: \{w = \frac{ - 4 - \sqrt{52} }{2} \} }} \\ \\ { \rm{either \: \{w = 1.6 \} \: \: or \: \: \{w = - 5.6 \}}}[/tex]

The length of a rectangle is 5cm more then the width. the perimeter of the rectangle is 38cm.find the length and width of the rectangle?
Answer:
Length - 12
Width - 7
Step-by-step explanation:
38 = 2((5+x) + x)
38 = 10 +4x
28=4x
x=7
7+5=12
Given : The length of a rectangle is 5cm more then the width. The perimeter of the rectangle is 38cm. Find the length and width of the rectangle?
Solution : According to the question, here we are given that the length if the rectangle is 5m more than its breadth and so the perimeter of the rectangle is 38cm. So, for this let's check the steps below
Let's assume the breadth be B
So, as we got that length is 5cm more than Breadth which is B + 5cm
Perimeter is 38cm
★ Perimeter = 2(Length + Breadth) ★
Perimeter = 2(B + 5cm + B) 38cm = 2(2B + 5cm) 38cm/2 = 2B + 5cm 19cm - 5cm = 2B 2B = 14cm B = 7cmFinding Length
Length = B + 5cm = 7cm + 5cm = 12cm
Finding Breadth
Breadth(Width) = B = 7cm
Therefore, Width is 7cm whereas Length is 12cm
The total cost of a pizza and 3 drinks is $19. The price of the pizza is $10 and each drink is the same price, d. 6) Which model represents the situation?
The total cost of pizza and drinks, is an illustration of a linear function.
The model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]
The given parameters are:
[tex]\mathbf{Total =19}[/tex]
[tex]\mathbf{1\ pizza =10}[/tex]
[tex]\mathbf{1\ drink =d}[/tex]
The cost of 3 drinks will be 3d

Substitute 19 for Total
[tex]\mathbf{10 + 3d = 19}[/tex]
Rewrite the above equation as:
[tex]\mathbf{3d + 10 = 19}[/tex]
Hence, the model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]

45. Anela and Jacob plan to attend a concert in Brady.
Anela will drive 375 km to Brady at a constant speed
of 75 km/hr, stopping one time for a 30-minute break.
Jacob will start 600 km from Brady and will drive at a
constant speed of 90 km/hr for 2 hours. He will take a
1-hour break and then drive to Brady at a constant
speed of 70 km/hr. To the nearest 0.1 hour, Jacob must
leave how much earlier than Anela in order for them to
arrive in Brady at the same time?
B. 2.5
C. 3.1
D. 3.5
Jacob must leave 3.5 hours earlier than Anela to arrive at same time.
What is speed?The distance traveled by an object in relation to the amount of time it takes to travel that distance is one way to define speed. Simply put, it is a measurement of an object's speed without providing direction. The term "velocity" refers to the speed at which we can obtain direction.
Given Anela distance to Brady = 375 km
speed of Anela = 75 km/hr
time taken by Anela is distance/speed
time taken by Anela = 375/75 = 5 hours
total time taken by time taken by Anela = 5 hours + 30 minute
30 minutes = .5 hours
total time taken by time taken by Anela = 5 hours + 0.5 = 5.5 hours
Jacob distance to Brady = 600 km
distance covered in 2 hours with speed 90 km/hr
= speed x time = 90 x 2 = 180 km
distance left = 600 - 180 = 420 km
time taken for 420 km at speed 70 km/hr
= 420/70 = 6 hours
total time taken by Jacob = 2 + 1 + 6 = 9 hours
difference in time of Jacob and Anela = 9 -5.5 = 3.5 hours
Hence Jacob should leave 3.5 hours early.
