Answer:
8
Step-by-step explanation:
y = 2x^2 -10
Let x = -3
y = 2( -3)^2 -10
y = 2 (9) -10
y = 18-10
y = 8
Answer:
45
Step-by-step explanation:
2:3
use the x
2x+3x=225
5x=225
divide both sides by 5
x=45

To find the x-intercept, substitute in 0 for y and solve for x.<span>x−2⋅0=5
</span>Multiply <span><span>−2</span><span>-2</span></span> by <span>00</span> to get <span>00</span>.<span><span>x+0=5</span><span>x+0=5</span></span>Add <span>xx</span> and <span>00</span> to get <span>xx</span>.<span>x=<span>5
</span></span>To find the y-intercept, substitute in 0 for x and solve for y.<span><span>(0)</span>−2y=<span>5
</span></span>Solve the equation.<span>y=−<span><span>5/2</span></span></span>
