Answer:
The answer is 0.60b + 0.30w = 150; 60 + 0.30w = 150
Step-by-step explanation:
Wei can purchase 300 balloons.
The model used for the problem is .
Step-by-step explanation:
Let the number of white balloons = x
The cost of blue balloons and white balloons are 60 cent = $0.6 and 30 cents = $0.3 respectively.
Wei purchased 100 blue balloons and have $150 to buy both balloons
Answer:
1/2
Step-by-step explanation:
the dilation factor should be 1/2
- if u count the dots on the sides of the preimage there are 2 dots that's the length
- if u count the dots on the real image it's 4
- therefore 2/4 to it's lowest term is 1/2
- so 1/2 is the scale factor

Answer:
y = 6x +2
Step-by-step explanation:
It is useful to start with the point-slope form of the equation for a line when you are given a point and a slope.
y -k = m(x -h) . . . . line with slope m through point (h, k)
y -(-22) = 6(x -(-4))
y +22 = 6x +24 . . . simplify
y = 6x +2 . . . . . . subtract 22
Hello!
*Solve the equation:
<span>**Separating the coefficients
</span><span>a = 3, b = -7 e c = 6
</span><span>***Calculating the value of the discriminant
</span>
Δ = b² – 4ac
Δ = (-7)² – 4.3.6
Δ = 49 – 72
Δ = - 23
p.s.: <span>Δ <0. When the discriminant is less than zero, there are no real roots.</span>
