Answer:
b)42, x=-2
Step-by-step explanation:
Answer:
The option 'b' is correct.
Step-by-step explanation:
Given the function
[tex]f\left(x\right)\:=\:10x^2\:+\:40x\:+\:42[/tex]
Determining the y-intercept
The y-intercept can be obtained by setting the value x = 0
[tex]y\:=\:10x^2\:+\:40x\:+\:42[/tex]
[tex]y\:=\:10\left(0\right)^2\:+\:40\left(0\right)\:+\:42[/tex]
[tex]= 0+0+42[/tex]
[tex]=42[/tex]
Therefore, the y-intercept is:
(0, 42)Determining the axis of symmetry
Given the equation
[tex]y=\:10x^2\:+\:40x\:+\:42[/tex]
For a parabola in standard form [tex]y=ax^2\:+\:bx\:+c[/tex]
the axis of symmetry is the vertical line that goes through the vertex
[tex]x=\frac{-b}{2a}[/tex]
so
The axis of symmetry for [tex]y=ax^2\:+\:bx\:+c[/tex] is [tex]x=\frac{-b}{2a}[/tex]
[tex]a=10,\:b=40[/tex]
[tex]x=\frac{-b}{2a}[/tex]
[tex]x=\frac{-40}{2\cdot \:10}[/tex]
[tex]x=-2[/tex]
Therefore, the option 'b' is correct.

In circle C what is angle 2
Answer:
33 degrees.
Step-by-step explanation: Half of a circle is 180 degrees. If we view the half of circle with angle C on it we can see the other part of the half of circle is 147 degrees. Since we know half a circle is 180 degrees, we subtract our known variable from 180 to get our unknown angle C, 33 degrees.

9x - 60 = 18 + бх
What value of x makes this equation true?
Answer: x=26
Step-by-step explanation: first you would subtract 6 from both sides.
Next, you would add 60.
Lastly, you would divide both sides by 3.
So your answer is 26.
Answer:
x=26
Step-by-step explanation:
step 1: simplify both sides of the equation
step 2:subtract 6x from both sides
step3:add 60 to both sides
step4:divide both sides by 3

Step-by-step explanation:
find the points where the graphs of y=1-x and y=x-3 intersect algebraically
Answer:
The point of intersection is (2, -1).
Step-by-step explanation:
At the point of intersection both equations have same value of x and y.
y = x - 3
y = 1 - x
Since the 2 right sides are both = y:
x - 3 = 1 - x
x + x = 1 + 3
2x = 4
x = 2.
Substituting for x in equation 1:
y = 2 - 3 = -1.

An apprentice baker made 40 liters of 60% sugar syrup instead of 40 liters of 45% sugar syrup. How much syrup should she drain and replace with distilled water so that the resulting solution is 40 liters of 45% syrup? Will award brainliest!
Answer:
10 liters
Step-by-step explanation:
let sugar in x liters of 60 % sugar syrup be equivalent to sugar in 40 liters of 45 % sugar syrup.
x×60 %=40×45%
60x=40×45=1800
x=1800/60=30
40-30=10
so 10 liters of 60 % sugar syrup be replaced with 10 liters of distilled water to make 40 liters of 45 % sugar syrup.
Answer: The baker needs to pour off 10 liters of the solution and replace it with 10 liters of distilled water.
.6(40) = 24. .45(40) = 18 24-18 = 6 6 = .6(10) 10 liters must be substituted.
Step-by-step explanation:
The original 60% solution contains 24 L syrup and 16 L water.
A 45% solution must contain 18 L syrup and 22 L water.
The difference in syrup is 6 L. 10 L of the 60% solution contains 6 L syrup.
After pouring off 10 L, the remaining 30 L will contain 18 L syrup and 12 L water.
By adding 10 L water, the resulting solution is 18 L syrup and 22 L water.
18/40 = .45 which is the desired 45% syrup.

Answer:
108:72
Step-by-step explanation:
Answer:
The missing value in the ratio that will appear next is: 108 and the ratio is 108:72
Step-by-step explanation:
The pattern of equivalent ratios is given in the picture.
The ratios are equivalent which means that the simplest form of ratio will be same for all ratios in the pattern.
So,
[tex]\frac{18}{12} = \frac{36}{24} = \frac{54}{36} = \frac{72}{48} = \frac{90}{60} = \frac{3}{2}[/tex]
This means that the simplest form of ratio for upcoming in the pattern will be 3/2
Let x be the missing value in ratio
Then
[tex]\frac{x}{72} = \frac{3}{2} \\x = \frac{3}{2} * 72\\x = 108[/tex]
Hence,
The missing value in the ratio that will appear next is: 108 and the ratio is 108:72

Step-by-step explanation:
Solve for x first then solve for y.
If you can make my answer brainliest that would be much appreciated. Thanks!
The x- and y-intercepts of the linear equation
2x + 3y = 12 are (6, 0) and (0, 4).
What is a linear equation?A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Given, A linear equation 2x + 3y = 12.
To obtain the x-intercept we'll make y = 0 in the equation which is,
2x + 3(0) = 12.
2x = 12.
x = 6.
So, The x-intercept is (6, 0).
To obtain the y-intercept we'll make x = 0 in the equation which is.
2(0) + 3y = 12.
3y = 12.
y = 4.
So, The y-intercept is (0, 4).

Find the measure of Angle DBE then find the measure of ∠ABD?
Answer:
m<DBE =50°
m<ABD=150°
Step-by-step explanation:
Because of Straight Angles, All the angles will add up to 180 degrees
Let x be m<DBE
40+x+70+20=180
x+130=180
x=50
m<DBE will be 50 degrees
To find the m<ABD, we add m<FBA, m<FBE, m<DBE.
70+50+30=150
m<ABD = 150
Answer:
angle DBE=
Step-by-step explanation:
We know that angle ABE is a right angle because 70+20=90. Therefore angle CBE is also a right angle.
Now, 90-40=50 (angle DBE's measure)
Based on this, we can know that 20+70+50=140. Angle ABD is 140 degrees.
